TFT- LCD Operating mechanism

The structure of TFT-LCD is that Liquid Crystal is being filled between C/F Glass & TFT Glass. One Pixel consists of 3 sub-Pixels(R,G,B)and according to the number of the pixels, Display Resolution (SVGA,XGA,etc) is determined.

The TFT Matrix consists of Data Line(Carrying display data signal),Gate Line(Carrying signal for turn On/Off the TFT).Each TFT, on each sub-pixel, controls the amount of Applying Voltage between C/F glass electrode & TFT glass electrode for the Liquid Crystal.

The Applying Voltage changes the Direction of Liquid Crystal which changes direction of the Light. Transmittance rate of the Polarized Light, polarized by Polarizer, is controlled by Applying Voltage. As a conclusion, Displayed Light is now under-control of Display Data Signal.
