A dot matrix LED display most commonly forms each character on a grid of
- 5 x 7 dots.
- 3 x 3 dots.
- 2 x 7 dots.
Explanation from PART66Online
Each character cell of a dot matrix display is a rectangular grid of individually addressed dots, and the most common size is 5 columns by 7 rows. Thirty-five dots are enough to draw capital letters, numerals and common symbols legibly, including the diagonals and curves that a seven-segment cell cannot form. A grid of 3 x 3 or 2 x 7 dots is too small to give most letters a recognisable shape.
