What Is AM-TFT LCD Technology?
The MicroTouch flat-panel displays use active-matrix thin-film
transistor (AM-TFT) liquid crystal display (LCD) technology.
With AM-TFT LCD technology, a flat-panel display shows a video
image by using a matrix (rows by columns) of tiny liquid crystal cells.
The cells create the pixels (picture elements) that make up the image.
To be more exact, a cell actually exists for each color of each pixel on
the display. Each pixel is made up of three colors, or sub-pixels (red,
green, and blue).
Each cell has a thin-film transistor switch to turn a pixel on or off.
The ability to turn on a single pixel and turn off its neighboring pixels
results in an image with exceptional contrast and sharpness. Also, the
thin-film transistors let the system address and control each sub-pixel
individually. The result is a fast response time in displaying the image.
Video Resolution on a Flat-Panel Display
Flat-panel displays, unlike CRTs, are optimized to run at one
resolution. A flat-panel display has discrete points on the display that
determine the exact location of a pixel. Each flat-panel display has an
exact number of pixels associated with it. There is a one-to-one
mapping between the number of pixels and the video addressability,
sometimes called resolution.
Native Video Resolution (1024 x 768)
A flat-panel display is intended to be used only at the resolution
dictated by the number of pixels on the panel. For example, the 13.8"
and 15.0" Profile and ChassisTouch monitors have 1024 pixels across
the screen and 768 lines of pixels down the screen. Therefore, these
flat-panel displays can accurately display one resolution (1024 x 768)
at full screen.
