Scope note:

The smallest units of an electronic display of digital imagery. In a black and white display this unit registers as either on or off. With a color display, the number of colors that may be displayed are limited by the screen's 'pixel depth,' measured in bits. The resolution of computer displays is also measured in pixels: the higher the number of pixels, the greater the resolution of the image displayed.
