Background
An LED display (LED display) is a flat panel display, which is composed of small LED module panels and is used to display various information such as text, images, and video.
LED, i.e. light emitting diode (abbreviated). It is a diode made of a compound of gallium (Ga) and arsenic (As), phosphorus (P), nitrogen (N), indium (In) by controlling the display mode of a semiconductor light emitting diode, and can radiate visible light when electrons and holes are recombined, and thus can be used to manufacture a light emitting diode.
In circuits and instruments as indicator lights or to form text or numerical displays. The gaas diode emits red light, the gan diode emits green light, the sic diode emits yellow light, and the ingan diode emits blue light. The display screen manufactured by putting red and green LED wafers or lamp tubes together as a pixel is called a three-color or two-primary-color screen, and the display screen manufactured by putting red, green and blue LED wafers or lamp tubes together as a pixel is called a three-primary-color screen or a full-color screen.
The LED electronic display screen integrates the microelectronic technology, the computer technology and the information processing, and has the advantages of bright color, wide dynamic range, high brightness, long service life, stable and reliable work and the like. The LED display screen is widely applied to commercial media, cultural performance markets, stadiums, information dissemination, news distribution, security trading and the like, and can meet the requirements of different environments.
