LEDmatriisinäytöt

LEDmatriisinäytöt, also known as LED matrix displays, are electronic visual display devices that use a matrix of light-emitting diodes (LEDs) to form images or text. These displays are composed of a grid of individual LEDs, where each LED can be independently controlled to emit light. By activating specific LEDs in a pattern, a visible image or character can be created.

The resolution of an LED matrix display is determined by the number of LEDs arranged in its grid, often expressed as rows by columns. For instance, an 8x8 LED matrix has 64 individual LEDs. The size of each LED and the spacing between them also influence the overall size and visual quality of the display. These displays are commonly used in a wide range of applications due to their brightness, energy efficiency, and versatility.

Common applications include digital signage, scoreboards in sports arenas, information boards in public transportation, automotive taillights and turn signals, and as components in embedded systems and DIY electronics projects. The ability to display dynamic content, such as scrolling text, animations, and simple graphics, makes them highly effective for conveying information or attracting attention. Control is typically managed by a microcontroller or a dedicated driver circuit that sends signals to illuminate the LEDs in the desired pattern.
