Light Emitting Diodes
Commonly know as LEDs, Light Emitting Diodes are simple semiconductor devices that can produce light, when the correct voltage is applied to them.
LEDs are tiny light bulbs that fit into an electrical circuit board. Since LEDs are digital, they do not get hot like an incandescent bulb, also the filament does not burn out. The lifespan of an LED surpasses the short life of an incandescent bulb by thousands of hours.
A cluster of red, green, and blue diodes is driven together to form a full-color RGB pixel, perceived by the human eye as a colored dot. The pixel is the smallest unit of a picture that can be represented and controlled.
The Driver Board represents the brain of the module and is responsible for supplying the correct voltage to the LED/pixels.
The Driver Board decodes all the data that is supplied to the diode. In D3 media display systems, the TrueElement™ system supplies the processed data stream to the Driver Board.
An LED module is a self-contained collection of individual LED diodes. The pixels are spaced evenly apart on the module to form an array.
The measurement from center to center determines the pixel pitch. The pitch of the display determines the resolution of the display.
An LED display's matrix resolution represents how many pixels are on the display, usually expressed as the (H) height x (W) width. Selecting a smaller pixel pitch will increase the matrix resolution of the display ensuring a greater image quality.
