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.
