TFT LCD

TFT stands for thin-film-transistor. It consists of pixels, which are arranged vertically and horizontally. Pixels in the horizontal and vertical alignment determine the resolution of the display. let’s take an example, suppose you have an 1800×740 resolution display, that means, it has 1800 pixels aligned horizontally and the 740 vertically. Each pixel has three subpixels RED, GREEN, BLUE.

But do you know how does TFT LCD generates different colours? Answer for this is divided into four layers that are as follows:

1. Polarization layer

2. Thin Film Transistor

3. Liquid Crystal

4. RGB Colour filter
