Pixel [|pixel] A pixel, short for the term, “Picture Element” is a bunch of little dots that make up an image. Each pixel is composed of 3 colors such as red, green and blue. The screen is divided up into a matrix of millions of pixels. The smaller the pixel, the clearer the image but this requires more memory to store the color and intensity. Pixels usually come in rows or columns. On a display screen, pixels are usually made up of liquid crystals.
