LCD Panel:

A TFT LCD panel contains a specific number of unit pixels often called subpixels.

Each unit pixel has a TFT, a pixel electrode (IT0), and a storage capacitor (Cs).

Generation of colors:

The color filter of a TFT LCD TV consists of three primary colors - red (R), green (G), and blue (B) - which are included on the color-filter substrate.

The elements of this color filter line up one-to-one with the unit pixels on the TFT-array substrate.

Each pixel in a color LCD is subdivided into three subpixels, where one set of RGB subpixels is equal to one pixel.
