pistematriisinäytöt

Pistematriisinäytöt, also known as dot matrix displays, are a type of electronic visual display. They consist of a grid of tiny lights, typically LEDs (light-emitting diodes), that can be turned on or off independently. By selectively illuminating these points, patterns and characters can be formed, creating legible text and simple graphics.

The resolution of a pistematriisinäyttö is determined by the number of points in its grid, often expressed as a width by height. For example, a 5x7 pistematriisinäyttö has five columns and seven rows of LEDs. Individual characters are formed by activating specific points within this matrix to create a recognizable shape.

These displays were widely used in early electronic devices, particularly in calculators, digital watches, and early personal computers. They were also common in public information systems like digital scoreboards and electronic signs due to their robustness and relatively low cost compared to early graphical displays.

While largely superseded by more advanced display technologies such as LCD (Liquid Crystal Display) and OLED (Organic Light-Emitting Diode) for consumer electronics, pistematriisinäytöt are still found in some specialized applications where their durability, visibility in direct sunlight, and low power consumption are advantageous. They continue to be employed in industrial equipment, automotive dashboards, and certain point-of-sale systems.
