Other forms: pixels

A pixel is one of the small dots or squares that make up an image on a computer screen. The more pixels there are, the more the image looks real or accurate.

Any digital image is made up of pixels, and when someone talks about the resolution of a computer monitor or TV screen, they're referring to the number of pixels. Older televisions have around 300,000 pixels, but new high-definition TVs can have more than two million pixels, which produces a very sharp, clear image. The word pixel came from pictures, or pics, and element, and was coined in 1969.
