What is a TFT?
Short for Thin Film Transistor, a type of LCD flat-panel display screen, in which each pixel is controlled by from one to four transistors. TFT screens are sometimes called active-matrix LCDs.


What are the benefits of a TFT display?
A TFT display delivers crisp text, vibrant color and an improved response time for visual applications at the best resolution of all the flat-panel techniques, but it is also the most expensive.


What sets the TFT apart for other LCDs?
TFT displays use a separate tiny transistor for each pixel on the display. Because each transistor is so small, the amount of charge needed to control it is also small. This allows for very fast re-drawing of the display, as the image is re-painted or refreshed several times per second.


What are the differences between TFT and Color STN?
TFT displays utilize active matrix technology and feature transistors on every pixel. Color STN (CSTN) is a passive matrix graphic LCD with a color filter. It only has one transistor per each pixel row and column and features a lower refresh rate than TFTs.
