Whats the difference between TFT and LCD?
The terms TFT and LCD are often used together and interchangeably, but there is a subtle difference. TFT is a type of LCD output, but much better than the original LCD. LCD stands for Liquid Crystal Display, and TFT for Thin Film Transistor. The TFT display technology was developed by IBM. The original old style LCD monitors had a slow refresh rate and were prone to blur moving items on screen, while the much better TFT has a faster refresh rate for a better display. TFT monitors are often called flat panel displays, and they are slowly but surely replacing the old style “glass” or cathode ray tubes (CRTs) on people’s desktops. Nearly all LCD monitors today use TFT technology. TFT monitors are better than LCD because they use a separate tiny transistor for each pixel on the display, and because each transistor is so small, the amount of charge needed to control it is also very small. This is what enables the very fast refresh (re-draw) of the display, as the pixels are switched on and
