PEL, short for “Picture Element,” is where the word “pixel” originates.

On a digital display device, a pixel is the smallest graphical unit that makes up a digital image or graphic.

On a smartphone, monitor, or TV screen, a huge image is created by assembling lots of pixels into a mosaic. Hence, the image quality improves as the number of pixels on the screen that represent colors increases.


Each pixel consists of three primary colors Red (R), Green (G), and Blue (B).  To create a broad spectrum of hues, pixels combine the amount of light and colors represented by each subpixel.
