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). Â To create a broad spectrum of hues, pixels combine the amount of light and colors represented by each subpixel.
