An LED display consists of hundreds of tiny LEDs (light emitting diodes) mounted directly on a flat panel. Each LED is essentially a miniature lightbulb that emits colored light when a particular voltage is applied to it. Clusters of red, green, and blue LEDs are grouped to create the full-color pixels needed to produce an image. Since the LEDs themselves produce the pixels, the size of the LEDs and the distance between them (known as “pixel pitch”) determines the resolution of the display. Displays with very small LEDs and a fine pixel pitch will produce higher resolutions than displays with bigger LEDs and a large pixel pitch. However, these higher-resolution displays are also dramatically more expensive.
Some LED displays come with a mounting system built in, while others require the use of a separate mount. The narrow profile of LED displays allows for virtually limitless mounting options, including freestanding, wall-mounted, ceiling mounted, curved, and more.
