Description
Technical field
The invention belongs to field of electronic display, relate to the sub-display screen array of a kind of orderly controlledization LED electrical.
Background technology
LED display screen is a kind of novel information displaying media developed rapidly in the whole world in the 80's of 20th century, the lattice module composition large-area displays screen that it utilizes light emitting diode to form, there is the features such as reliability is high, long service life, adaptive capacity to environment are strong, cost performance is high, use cost is low, shoot up as one of the main product of flat pannel display, be widely used in the field of information display such as billboard, public display screen.
LED (Light Emitting Diode), light emitting diode is a kind of can be the solid-state semiconductor devices of visible ray by electric energy conversion.The heart of LED is the wafer of a semiconductor, and one end of wafer is attached on a support, and one end is negative pole, and the other end connects the positive pole of power supply, makes whole wafer by epoxy encapsulation.When electric current acts on this wafer by wire time, electronics will be pushed to the P district that its PN ties, and in P district, electronics is with hole-recombination, then will send energy with the form of photon, from making LED luminous.LED electroluminescent lamp can be divided into the polytypes such as monochromatic electroluminescent lamp, dual color light emitting lamp, three-colour light-emitting lamp, surface electroluminescent lamp, flashing lamp, voltage-type electroluminescent lamp.General brightness electroluminescent lamp, high brightness electroluminescent lamp, super brightness electroluminescent lamp etc. can be divided into again according to electroluminescent lamp intensity.
LED display screen (LED panel) is the display screen that a kind of lattice module be made up of semiconductor light-emitting-diode forms, it is the mode that the light on and off situation by controlling semiconductor light-emitting-diode shows, select the light on and off of corresponding light emitting diode according to various information such as the word that will show, figure, image, animation, video, video signals, thus realize the object of the various information of display.LED display screen has that antidetonation is shock-resistant, speed of photoresponse is fast, energy-conservation, luminescence efficiency is high, long service life, flexible in configuration, rich color and to advantages such as indoor and outdoor adaptive capacity to environment are strong, constantly perfect along with LED manufacturing technology, obtain very large popularization at home and abroad, be widely used in various indoor, the outdoor display screens such as large-scale theater, store, the gateway in hotel and the nameplate of toilet.
Realize good driving and display frame, not only need only to light LED, and need to realize LED array according to orderly the lighting of distribution.
