Dot-matrix display

A 16×2-character dot-matrix display, where each character is made from a grid of 5×7 dots

A dot-matrix display is a low-cost electronic digital display device that displays information on machines such as clocks, watches, calculators, and many other devices requiring a simple alphanumeric (and/or graphic) display device of limited resolution.[1]

The display consists of a dot matrix of lights or mechanical indicators arranged in a rectangular configuration (other shapes are also possible, although not common) such that by switching on or off selected dots, text or graphics can be displayed. These displays are normally created using LCD, OLED, or LED technology.[2][3] A dot-matrix display controller converts instructions from a processor into signals that control the individual dots in the matrix so that the required display is produced.
