A dot-matrix display is a display device used to display information on machines, clocks, railway departure indicators and many other devices requiring a simple display device of limited resolution.

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 lights, text or graphics can be displayed. A dot matrix controller converts instructions from a processor into signals which turns on or off lights in the matrix so that the required display is produced.

Common sizes of dot matrix displays:

  • 128×16 (Two lined)
  • 128×32 (Four lined)
  • 128×64 (Eight lined)

Other sizes include:

  • 92×31 (Four or three lined)

  • A common size for a character is 5×7 pixels, either separated with blank lines with no dots (in most text-only displays), or with lines of blank pixels (making the real size 6×8). This is seen on most graphic calculators, such as Casio calculators or TI-82 and superior.
  • A smaller size is 3×5 (or 4×6 when separated with blank pixels). This is seen on the TI-80 calculator as a "pure", fixed-size 3×5 font, or on most 7×5 calculators as a proportional (1×5 to 5×5) font. The disadvantage of the 7×5 matrix and smaller is that lower case characters with descenders are not practical. A matrix of 11×9 is often used to give far superior resolution.
  • Dot matrix displays of sufficient resolution can be programmed to emulate the customary seven-segment numeral patterns.
  • A larger size is 5×9 pixels, which is used on many Natural Display calculators.
