What is a TFT-LCD?
A TFT is a type of active matrix LCD. TFT technology is used in applications in the medical, commercial, industrial, marine, military, transportation, financial, marketing, and hospitality industries. A display made with TFT (thin film transistor) technology is a liquid crystal display (LCD) that has a transistor for each pixel. Having a transistor at each pixel allows the current that triggers pixel illumination to be switched off and on more quickly. In other words, the amount of current needed to control each pixel is small, which allows for a quick response time.
Glossary of Terms
Active area The viewing area of the LCD glass, the dimensions of the conductive area.
Active matrix display A type of display that uses thin film transistors to individually control each pixel. These displays offer wide viewing angles, fast response times, and high contrast ratios.
Aspect ratio Aspect ratio describes the dimensions of an image by comparing the width and the heigth of an image.
Backlight LCDs are illuminated by the use of separate light sources, or backlights, that are built into the back of the LCD unit. The most commonly used backlights are LED (light emitting diodes), EL (electro luminescence), or CCFL (cold cathode fluorescent lighting).
Luminance Luminance refers to the amount of visually effective light emitted by the light source of a panel. The luminance is often measured in candelas per square meter (cd/m2), or nits.
CCFL (cold cathode fluorescent lighting) CCFL, or cold cathode fluorescent lighting, is a type of fluorescent backlighting. Often, this technology is replaced with advanced LED technology.
Color saturation Color saturation refers to the measurement of a color's purity. High saturation images appear vivid in color while low saturation images are more flat and dull.
Contrast ratio The contrast ratio compares the brightest part of an image with the darkest part of an image, in the form of a ratio; for example, 1000:1. A high contrast ratio is a desired characteristic of display specs.
DVI (Digital visual interface) A digital visual interface (DVI) is used to convert analog signals into digital signals to ensure compatibility of both analog and digital monitors.
DDI (Display data channel) Display data channel (DDC) is the VESA standard adaptor between a video adapter and a monitor.
Inverter An inverter's job is to convert direct current (DC) to alternating current (AC).
LCD (liquid crystal display) A liquid crystal display (LCD) is a commonly used display; the advanced technology has many benefits over CRT panels, such as longer lifespan, lower power consumption, and more efficient technology.
LVDS (low-voltage differential signaling) LVDS is an electrical signaling system that runs at very high speeds over twisted-pair copper cables.
NTSC (National Television Systems Committee) The National Television System Committee (NTSC) is the body defining the television video signal format used in the United States.
Physical dimensions This refers to the outside dimensions of the display module, including height, width, and length.
Polarizer A polarizer is a film inside an LCD. In conjunction with other films, polarizer films manipulate light for maximum output.
Power consumption Measured to determine the power usage of a particular device. Power consumption is measured in watts.
Resolution Resolution, or display resolution, applies to the number of columns and rows of pixels created in a display (e.g. 1080x960, a panel's resolution is written as width x height). A 10" display can have the same resolution as a 15" display.
TFT (Twisted film transistor) A thin film transistor (sometimes called active-matrix) is a technology that provides the best resolution in the current panel technologies.
TN (twisted nematic) This display consists of a nematic liquid crystal place between two panels of glass (inside the display). A twisted nematic display is structured in a way to utilize polarized light.
Viewing Angle Viewing angle is the term used to describe the maximum angle in which data on a display screen can be viewed while still maintaining good visual clarity.
