The thin-film transistor liquid crystal display (TFT-LCD) is a cutting-edge display, which screens picture information by adjusting the amount of light permitted.

TFT is a circuit formed with semiconductor films on a thin glass substrate to control liquid crystals. This circuit plays a vital role in controlling each pixel, the basic unit of a picture image.

The color filter displays a color image by coating the pixel (red, green and blue) on a glass substrate.
