Using AGDisplays for component design, assembly and integration allows customers to have complete control over the designed unit, down to selecting preferred interface signal.

This service saves customer time and money by alleviating the need to personally design a safe unit; AGDisplays allows customers to take a hands-off, worry-free approach, if needed. Further, AGDisplays sources all components needed, so customers no longer are required to shop, price compare and track lead times for various design components.

coverglass design & integration

AGDisplays’ cover glass design and integration service for customers looking to improve optical clarity as well as increase LCD strength. We offer different material substrates that each provide unique benefits to your LCD. On top of cover glass solutions, we offer to integrate a variety of optical coating solutions with the cover glass for added benefit and performance.

Cover glass options may be enhanced or treated for increased strength; they promote sunlight readability, ruggedize display, protect from EMI interference and enhance optical functionality. Futhermore, quality cover glass coatings can influence and control transmittance, resistance, absorbance and reflectance.

A cover glass substrate is integrated with a specific bonding method: OCA, optical or tape bond. Each bonding method has exclusive specifications. Depending on environment and application, an LCD will benefit from one of these methods. To learn more about bonding, scroll to see the FAQs for our OCA, Optical and Tape Bonding Services.

Our optical coating selections feature focused properties per coating, including anti-reflection, anti-glare, oleophobic/hydrophobic, transparent conductive coatings.

Depending on design specifications and the application environment, AGDisplays personally works with your team to distinguish which cover glass options are best for your LCD design. We aim to build a better suited quality design for improved LCD protection and performance.

Anti-Reflective (AR) treatment reduces ghost images, which are often produced in builds that have multiple reflective surfaces. These coatings are all dielectric single or multilayers and are designed for low reflectance and high transmittance in the UV, visible, and near IR spectral bands. Operating temperature for this coating is typically ≥300°C, and reflectance is as low as 0.05%; the surface is durable and easy to clean.

Anti-Glare (AG) reduces glare on a screen to increase readability. This film is matte, meaning it will not reflect ambient light. It also reduces fingerprints and smudges, preserving high reflection, even as smudges may occur. Along with low reflection and high resolution, the film also provides an added layer of display durability.

Oleo/hydrophobic treatment resists dirt, water, grease and oil to prolong and enhance glass performance. Oil resistant (Oleophobic) coating reduces adherence of finger-prints and smudges to help maintain pristine image quality even after repeated cleaning. This optical coating provides mechanical protection and repelling properties while achieving < 0.5% photopic reflection and high throughput. It offers resistance to severe abrasion and scratches. Overall, this allows surfaces to be easy-to-clean, and repeated removal of fingerprints while employing durability properties to prevent abrasion and scratches.

Transparent conductive coatings are high durable coatings that can be used in electro-magnetic shielding and electrical heating display applications. These coatings allow for low reflectance and are specific in their applications. Consult an AGD expert for more information on transparent coating.

EMI shielding integration

What is EMI? EMI (electromagnetic interference) is the disruption of operation of an electronic device when it is in the vicinity of another electronic device. Each electronic device emits an electromagnetic field; when emissions cross, it may interfere with normal operations of the electronic device.

AGD’s EMI Shielding Integration service is for customers who need to block electronic interference between their LCD and the equipment that may negatively affect it. EMI shielding provides “immunity” for electronic components that are susceptible to EMI interference. Typical EMI shielding integrations involve installing a metal box to protect the vulnerable unit.

AGDisplays has several mesh and film solutions that allow for a passive LCD installation that will not intrude on electrical components or power consumption. Our film solutions allow optimum optical performance while providing a high level of protection.

AGDisplays offers various EMI solutions to our customers so we can meet any specification. Level of protection is custom, based off of customer need.

high bright integration

If you find your screen is dull and colorless, upgrading to high powered LEDs will breathe new life into your unit, allowing for a vibrant and long-lasting display. AGDisplays provides advanced high bright (1000+ nits) LED rails with high-output, low consuming to enhance display color and contrast; maximize efficiency and lifetime of your panel by upgrading to a stable design including high bright LED rails and a constant current LED controller.

Our LED design solutions are customized to your project’s need, with design options and flexible brightness customization. Design flexibility allows for edgelit design or direct backlight array options. Our Generation 4 LED rails provide high bright solutions while keeping a low environmental footprint. With small, powerful LEDs, our LEDs boast added protection with low power consumption.

LED backlighting is typically designed as edge-lit or in a direct backlighting arrangement. Both types have the LEDs concentrated into a diffuser source (light guide of the display) distributing the light uniformly throughout the viewing area. With an edge-lit backlight design, LEDs are aligned along edge of the internal light guide of the LCD. The backlight array may be mounted on one, two, or all four edges, depending on the size of the display and the amount of luminance required. With this design, light from the LEDs is captured and spread across the viewing display by way of the light guide. Benefits of this design include a slimmer profile of the product, lower cost of LEDs.

In a direct backlighting arrangement, LEDs are placed in a flat array behind the light guide and the diffuser plate. Direct backlighting works as a uniform source of backlighting, like most CCFL LCDs. One of the pros of integrating a direct backlight arrangement allows for local-dimming aspect, which means the display is able to dim zones behind the dark areas of the screen in fairly specific areas to make the image really pop, drastically increasing the apparent contrast ratio providing a more accurate color adjustment and enhancing overall viewing quality. Blacks are true black and grays are more defined.

AGDisplays is on our Generation 4 LED rail, white LED model. The LED technology boasts a high bright output and a low environmental footprint. With every generation, AGDisplays provides customers with the latest innovative technology on the market.

As LED technology advances, our high-powered LED rails become smaller, allowing for integration into slimmer and lighter designs. Overall LED lifespan reaches up to 100,000 hours. LED upgrades also provide for better environmental protection against shock and vibration, extreme humidity and frigid temperatures. What’s more, our LED rail technology is environmentally safe and ROHS-compliant; they are mercury- and lead- free and have reduced EMI emissions.

Compact and rugged, LEDs are extraordinarily resistant to shock and vibration; they are free of glass and other small, breakable parts. Given the nature of the LED, there is almost no limit to shape and size in which they can be manufactured. If your new or existing panel design contains CCFL or LED backlighting, be sure to consider upgrading to the latest high bright LED technology.

Thermal design considerations are very important; integrating an LED backlight typically requires heat management. It is necessary to dissipate operating heat as efficiently as possible, keeping sensitive LED components safe from thermal damage created by dissipation of current. Inefficient heat management can damage or shorten the life of an LED backlight. AGDisplays continually inspects the value and quality of our products. With each integration of our latest generation LED technology, we also integrate high efficient heat management technology to preserve the lifespan of your LED.

NVIS design and integration

AGDisplays implements state of the art NVIS compliant LCD backlight solutions for full filter and dual mode filtered applications. Whether the need to be compliant to MIL-STD-3009 or merely compatible with NVG equipment, we offer solutions tailored to accommodate your requirements and your existing LCD unit.

NVIS compatible LCD units benefit those markets heavy in navigation, surveillance, rescue, public safety and law regulation. In Avionics, NVIS devices allow aircrews to see during night flight and aid in navigating around obstructions. Military and Defense applications use NVIS in night combat and surveillance operations. In Public Safety, NVIS aids in law enforcement, search and rescue operations, maritime public safety, and lends a hand with homeland missions. NVIS aids during training simulations, such as during flight, marksmanship, combat and group missions.

NVIS improves situational awareness at night; it dramatically reduces the possibility of collision for those in moving vehicles. AGDisplays offers a full front NVIS passive installation or a robust dual mode high bright solution for enhanced day and night use. These systems have been used for years by the police and military.

AGDisplays offers two unique NVIS solutions; one solution allows for a passive installation while we offer a second, more robust integration that allows for regular day use and NVIS-enabled filtering at night.

Displays must be visible to the unaided eye while emitting very low levels of IR (infrared). If a display emits small amounts of radiant energy within the response range of the IR-sensitive photocathode, it may degrade the performance by impairing the resolution or sensitivity of the imaging system.

NVIS-compatible illuminated displays do not interfere with NVIS and remain readable to the unaided eye. NVIS compatibility also means that enemy's NVIS system will find it difficult or impossible to detect the light source at a distance.

A normal incandescent, EL (electroluminescent), or LED light source interferes with NVIS because it emits significant IR radiation within the response range of NVIS. This excess IR causes interference in several ways:

  • IR reflections from the crew station canopy produce ghost images in the NVIS.
  • IR can bloom the goggles, creating a halo-like glow around the displays and reducing visibility.
  • High levels of IR activate the automatic gain control (AGC) and further degrade sensitivity and resolution.

Our more robust solution, AGDisplays designs and manufactures a custom dual mode backlighting solution for LCDs which allows excellent readability in high ambient lighting, while also providing a secondary mode in which the panel’s illumination is NVIS compliant. Our NVIS solutions are ideal for use in military, avionics and industrial applications, including limited mobile devices.

The backlighting system consists of two backlight sources that operate independently of each other. The first light source is bundled; the second light source is an NVIS compliant light source that can have Class A or B filters. All optical components fall within MIL-STD-3009. In night mode, brightness is dropped and light is filtered to allow compatibility with night vision imaging systems.

With the installation of our Generation 4 high bright LEDs, panel readability and clarity in ambient light is maximized as well as enhancing sunlight readability. In day time mode, our Gen 4 high Bright LEDs run at a stable current, displaying sharp and bright graphics, ideal for use in ambient environments.

This solution is bonded using a liquid optical bond, providing increased LCD ruggedization and improved optical features. Dual mode backlighting is compatible with various optical coatings to increase viewability, as necessary. Optical coating options include anti-glare or anti-reflective films. Durable glass provides protection from abrasions and spills.

AGDisplays offers an NVIS filtering material for devices not looking for an active enhancement. Our polymeric material has been integrated and deployed in numerous military applications.

This solution provides an impressive level of absorption in the near-infrared and stability under solar and temperature exposure, with minimal impact to the visible spectrum. This solution offers a passive installation with safe removal.

Our unique polymeric material is designed with optical performance in mind. The processes used in these optical filters allow for unequal rendering of display red chromaticity. The material is specifically designed to work with LED lighting, and preserves high visibility transmission and low radiance. AGDisplays realizes your specifications are unique, so we offer this solution in range of thicknesses to ensure it can meet your physical criteria.

OCA, optical and tape bonding

An LCD is made of a stack up of various types of materials that create and enhance certain optical properties of the LCD. Often, LCD build designs are constructed in such a fashion that air gaps are left between the layers of its components. Internal reflections are created by the air gap created between these layers. Optical quality can be greatly affected; internal reflections decrease optical clarity, along with the leaving the LCD vulnerable to contamination and moisture collection (condensation). Bonding is the process in which two or more components inside the LCD are bonded together with a type of adhesive to create a single optical index. Put simply, the air gap between the LCD and the cover glass is eliminated, therefore benefiting the LCD functionality in a matter of ways. LCDs are optically improved not only for direct sunlight environments, but in any type of ambient light conditions.

Bonding is also used in displays to ruggedize layers/components together. This creates a stronger and more durable display overall and helps dissipate temperature extremes.

LCD bonding is an adhesive process in which a specific form of adhesive is integrated into the panel stack up to provide an adhesive grip for components inside the LCD. Our bonding options increase panel ruggedization and also prolong product lifecycle, help dissipate temperature extremes and more. Benefits to the end user include enhanced product performance, increased environmental resistance, increased resistance to general wear and tear.

AGDisplays offers different types of bonding services: OCA Bond, Optical Bond, Perimeter Bond. Each service has unique benefits, depending on the need of your specification.

This method uses a liquid bonding adhesive and is the most robust solution of all of our bonding offerings. This robust solution may involve a full lamination, consisting of two outer substrates sandwiching alternating layers of adhesives and other elements. The solution creates superior LCD strength and prevents a shattering screen and less vulnerable to contamination and moisture. It also provides extended operation temperature range capability and increases touch response. The non-yellowing material provides excellent UV resistance. Laminated applications can include: EMI shielding, privacy filters, enhancement filters and security screens.

Optical bonding increases quality and lifespan of LCD, keeping overall replacement costs low. Although our optical bonding service is the strongest bonding service we provide, the solution is reworkable through our production process. AGDisplays performs quality assurance measures and testing on each LCD to ensure specifications are met. Our facility is capable of performing low and high volume production.

Optically Clear Adhesive (OCA) bond is a dry film material that is pressure-sensitive. AGDisplays typically uses thin OCA adhesive in small frames and thin display applications. The film application allows for precise and unique processing during production. It is suitable to outdoors and harsh environments. OCA film has silicone’s core properties such low conductivity, low chemical reactivity/thermal stability and the ability to repel water. The installed film allows for excellent display readability and contrast while having anti-reflective/anti-glare features. What’s more, condensation and fogging is prevented when the air gap is eliminated. AGDisplays offers the material in varying thickness, allowing for flexibility in design builds. This option is cost effective, giving customers up to 50% cost savings versus robust bonding services.

Perimeter, or tape bonding involves using a highly adhesive tape to seal the edges of the LCD. A great benefit to using tape bonding is its ability to be retrofitted into any size LCD display. The continuous bond around the perimeter of the display distributes stress over the entire bonded area, providing static or dynamic strength. The benefits of this solution includes resistance to extreme weather, vibration dampening, reworkability, and viscoelasticity. Tape bonding is a low-cost and practical solution while still providing adequate ruggedization with a high adhesion.

passive and active film enhancement

If you find your panel display is dull or unclear, consider film enhancements for a quick and cost effective upgrade to panel performance. Film integration solutions provide benefits such as privacy options, viewability features, increased optics, LCD protection and contrast enhancement. Installing enhancement films is considered a ‘passive’ LCD enhancement which means they are installed without compromising electrical specifications or increasing power consumption.

When integrated into an LCD with a light source, films reflect and/or refracts light to create the desired benefit. Multiple films and configurations may be used in one solution. Benefits to user include quick turnover, cost effective, and no power consumption increase. Some enhancements provide a shielding layer to the front glass of your LCD, protecting it from scratches and contamination.

Evaluating and analyzing the panel's stock film stack is a crucial step in determining the most effective passive film enhancement. Our experienced technicians evaluate and suggest the best recipe available to optimize brightness. While the addition of brightness enhancement films can achieve a brightness increase, many times multiple configurations can be assessed to allow the customer several custom performances.

We maintain state-of-the-art class 1000 clean room facilities equipped with an automated laminating and temperature controlled de-laminating equipment. Our passive integration technology has a variety of benefits for your LCD in terms of performance results.

AGDisplays assures that all enhancement processes produce the desired outcome for our customers, while maintaining the integrity of the LCD panel. AGDisplays has a precise method in terms of final quality control testing. We do final QC testing on every single product that leaves our facility. Our final QC testing is how we maintain a low fallout percentage on not only our film enhancement processes, but on all of our services. Furthermore, AGDisplays employs incoming quality control testing procedures to ensure quality products. This not only guarantees us that we are receiving quality products, but it also helps us pinpoint any defects we may come across while troubleshooting.

Integrating a film enhancement solution is available on your existing display and saves you money by avoiding the purchase of a whole new unit.

Typically, the customer informs us of their desired result, and we engineer a film stack configuration to meet those specifications. Some popular enhancements are below. High bright enhancements increase brightness by 40 to 145 percent and intensify the display's contrast.

Anti-glare enhancements minimize reflections from ambient lighting, noticeably improving readability.

Anti-reflective enhancements improve the durability and lifetime of your display surface. Our anti-reflective properties increase the contrast and sharpness as well as decrease the reflection from your LCD screen, without having to increase your LCD's power consumption.

Quarter wave retarder films offer uniform birefringence increases the wide angle view performance of the panel while keeping haziness low.

Privacy films decrease viewing angles, increasing privacy and keeping information away from prying eyes. This is a great tool to keep your customers' sensitive data safe while they use ATMs, mobile devices and point of sale (credit/debit card) applications.

BRIGHTNESS ENHANCEMENT FILM (BEF): Brightness enhancement film or BEF film can increase the brightness of liquid crystal displays through improved management of the existing light produced by the backlight. The prisms on the brightness enhancement film redirect light from the backlight toward the LCD user. Brightness Enhancement Films utilize refraction and reflection to increase the efficiency of your backlight source, regardless of the source (CCFL or LED). BEF allows light to exit the LCD at a specific angle. Light outside of this angle is reflected back into the LCD until it exits at the proper angle. Multiple Brightness Enhancement Films used in unison can absorb and reflect light from both the 0 and 90 degree absorption angles and can increase the light output while maintaining the recommended current draw of the stock LCD.

DUAL BRIGHTNESS ENHANCEMENT FILM (DBEF): Another transmissive film used to increase brightness is the Dual Brightness Enhancement Film, or DBEF, as it is commonly referred to. DBEF is a thin film reflective polarizer that captures and uses light normally lost to absorption in the bottom LCD polarizer and redirects it until allowing it to exit the LCD backlight assembly at the proper angle. Using DBEF film in conjunction with BEF film can often offer the highest yield of light output. The correct mating of BEF and DBEF films is critical when designing a film enhancement to assure the maximum return is achieved. Multiple versions of DBEF are available; this allows the correct film to be chosen for each specific application. AGDisplays stocks multiple version of this film so we can quickly identify, and implement the correct solution, resulting in less time loss during the engineering stage of development.

ENHANCED SPECULAR REFLECTOR (ESR): ESR is an acronym for Enhanced Specular Reflector; this reflective film is designed to maximize the usage and distribution of light from an LCD's light source. The ESR film is placed in the backlight cavity, providing improved bulb cavity light extraction. The ESR is a thin, 100% polymer film with a reflectivity of 98.5% across the visible spectrum; it uses hundreds of microscopically thin polymer layers that alternate in size to reflect light. Integration of the film also allows more light to be recycled, reducing the required energy needed to power the LCD. Moreover, the light distribution from the LCD's light source increases the LCD's viewing angle. This film used in conjunction with other brightness enhancing films can obtain the highest light output, especially when designing a solution for use in direct sunlight light.

LIGHT DIFFUSION FILM: Diffusion films improve LCD functionality by providing brightness uniformity throughout the active area. Light travelling through the stack up of an LCD will have no direction and be travelling in all directions. The function of the diffuser film is to redirect light in one direction, toward the next film. Employing diffuser films can provide up to 98% total light transmittance. This film also works by blending light from different lamps together, creating even intensity and distribution of the light. PRIVACY FILMS: AGDisplays uses specialized light control films to block screen images from those who are not directly in front of an LCD's viewing area; these films work but acting as blinders to those who are not in direct view of the LCD. Light control films direct light only in the direction of the user. Adding a privacy film layer protects screens from scratches and smudges, extending the life of your product. AGDisplays can help you protect your customers' information with the installation of privacy film on your panels.

touchscreen design and integration

There are multiple touch technologies on the market: resistive, surface capacitive, projected capacitive, surface acoustic wave, and infrared. Without touchscreen technology, user speed and accuracy may be insufficient and confusing.

AGDisplays designs compatible solutions for existing LCD designs or we also provide a new unit that is touch compatible. Many LCD panels are not equipped with a touch sensor. AGDisplays turns customer LCDs into touchscreens with the quick integration of a compatible touch sensor. We also perform repairs, replaces or enhances touchscreen technology.

Product application plays a major role in the type of technology needed, and each touchscreen technology has pros and cons, depending on the application’s environment. It is important to work with the AGDisplays design teams to ensure the best touchscreen match as well as safe and secure touch sensor integration.

By using AGDisplays’ Touchscreen Design and Integration service, you are integrating an intuitive platform into your unit: a mouse and keyboard is familiar to most, but touch screen comes intuitively to users even if they don’t have a computer background.

Touchscreens are quick and responsive, allowing employees to juggle multiple tasks efficiently. Touch screen requires less concentration to use than the standard mouse/keyboard combo. There is up to a 20% reduction in response time for touchscreen users versus traditional input methods.

Save money by integrating touch functionality into your existing display, instead of spending unnecessary money on a whole new LCD touchscreen unit.

Resistive Touchscreen: This is the most common touchscreen on the market. The sensor consists of glass or acrylic panel which is coated with electrically conductive and resistive layers made with ITO (indium tin oxide). The thin layers are separated by invisible spacers. When initiating a point of contact with a resistive touch screen, the stylus/finger creates pressure and contact between the resistive circuit layers, allowing for a complete circuit. The point of contact acts as a pair of voltage dividers with connected outputs, which causes a change in electrical current and the panel can then identify the location of the touch. This touchscreen is activated with virtually any object such as a finger, a stylus, pen, etc. Resistive touchscreens are affordable, highly durable, and have a high resistance to water.

Surface Capacitive Touchscreen: In this build, sensors in the four corners of the display detect capacitive changes made by a touch. The coordinates of the position at which the finger touches the screen are identified by measuring the resulting changes in electrostatic capacity at the four corners of the panel. Protective coating protects touchscreen membrane from scratches and abrasions. A touch can only be detected when it is made with a conductive object such as a finger or hand. The protective coating of the touchscreen provides increased transmissivity. Benefits of this touchscreen includes a glass layer for brighter, sharper images and the touch allows for great contamination resistance.

Projected Capacitive Touchscreen: This touchscreen features superior optical clarity. Touches are sensed through a protective layer (such as glass shield or other substrate). Projected capacitive technologies detect touch by measuring the capacitance at each addressable electrode. When a finger or a conductive stylus approaches an electrode, it disturbs the electromagnetic field and alters the capacitance. This change in capacitance can be measured by the electronics and then converted into X,Y locations that the system can use to detect touch. There are two different sensing methods: self capacitance and mutual capacitance:

  • Self capacitance: to sense touch in a self-capacitance implementation, the electronics scan through each electrode and measures the amount of current on each electrode to establish a steady-state current. When a finger or grounded conductive stylus approaches the screen, they couple to the electrodes and increase the current draw as it creates a path to ground. By determining which row and column is closest to the touch location, and using interpolation for higher precision, a controller can determine the location of a touch.
  • Mutual capacitance: projected capacitance touchscreens intentionally create mutual capacitance between elements of columns and rows in the vicinity where each intersect the other. This allows the system electronics to measure each node (intersection) individually to detect multiple touches on the screen during one screen scan.

Surface Acoustic Wave Touchscreen: The basic principles of surface wave technology are that the surface wave energy can be attenuated by an energy (sound) absorbing material touching the surface, and that the direction of the surface wave energy can be changed or directed by patterns or ridges with specific orientation. When you touch the screen, you absorb a portion of the waves traveling across it. The received signals for X and Y are compared to the stored digital maps, the change is recognized, and a coordinate is calculated. The sensor does not use an electrical signal or use conductive coatings; it uses clear glass for extra durability and extended lifetime.

Infrared Touchscreen: The controller interface strobes the IR emitters both in the X and Y plane to provide a grid of light beams that can be broken by a finger or any touch implement. When a touch is made by a finger or touch implement, one or more beams of light in the matrix will be broken and the controller interface can tell where the touch is positioned to block those particular beams. The monitor and touch overlay are discrete, allowing for upgrades or easy replacement. This sensor performs in just about any indoor lighting environment (unlike many camera-based or vision-based systems, such as the SUR40). Infrared touch sensors scale to larger displays and is economical; it allows up to 40 simultaneous touch points. This sensor is best suited for flat panel displays and large applications, especially when weight of touch sensor is a factor.

zero pixel inspection

Many companies require documentation certifying inspections have been completed. Our service provides zero pixel inspections and certificate of conformance documents for your panel.

Dead pixel policies vary from manufacturer to manufacturer. There are thousands—if not millions—of pixels in every panel. A panel with 1080x1920 contains 2,073,600 pixels. Many companies have acceptable standards for a certain amount of allowable dead pixels—meaning you may have been sold a panel with dead pixels.

We receive panels from OEM before they reach the customer:

  • AGD inspects panels for zero pixels per customer specification
  • We inform customer of failing panels, and will perform LCD exchange with OEM, if OEM spec grade fails.

Customer may send LCD panels directly to AGDisplays for inspection:

  • AGD inspects panels for zero stuck or faulty pixel quality
  • AGD confirms and documents findings for verification
