Led electron shows screen is collect microelectronics technology, photoelectron technology, computer technology, information processing technology the large indication system at an organic whole. It with its colourful, dynamic range is wide, brightness is tall, life is long, character of service is stabilized and become the person above average in indication media with each passing day, wide application is released at transmission of advertisement, negotiable securities, information, news wait for a respect, it is current the very advanced indication media on international.
Led electron displays screen (Ledpanel) it is to carry certain control kind, the indication screen that the array of Led parts of an apparatus that is used at showing all sorts of information such as signal of character, graph, image, animation, prices, video, kinescope forms.
Of indication method evolve into the history
Traditional Bai Jideng, cannot overcome its power consumption is big, the blemish with brief life, advertisement of box of lamp of neon lamp, advertisement, planar fascia although color is bright beautiful, but change is drab, cannot broadcast video image ad more; Although magnetism reprint can borrow computer to go all out fit simple pattern, but oneself does not have glow cause, nightly use effect is poor. In last few years, as the rapid development of microelectronics technology, automation technology, computer technology, produce the reachs new material newlier application of craft, make the development that the brightness of LED chip, life got advance rapidly, make its application field increasingly extensive thereby, LED shows screen market gets great progress. After 93 years, the occurrence that glow of freeboard bright blue, gules, green is in charge of, make implementation true color shows screen becomes a fact, what screen gets people show to love outdoor, special the application that waits for a domain in stadium house, advertisement, news is wide with each passing day. From future development trend looks, have a few kinds of medium of video effect at present, each has his strong point of its performance dominant position:
Cathode is in charge of (Crt) or quartz is in charge of (Dv) large TV: Cost is very high, can accomplish 37 inches only normally, bulk is about to be restricted greatly again, or else needs to exceed big picture and when be being used indoors, effect ideal.
Chromatic liquid crystal shows (Led) : Same cost costly, circuit is complex, area cannot too big, and the effect that suffers a perspective is very big, can inspect angle very small, but picture exquisite, visual perception is good.
Image is umbriferous equipment (Projector) : Small, definition differs brightness (the picture gets light inhomogenous) , the advantage is installation convenient, safeguard simple.
TV wall (Tv-wall) : The surface has minute of secant, there is an eyewinker to feel on the vision, the effect on the brightness when applying outdoor is poor, unwell at showing a character, but fruit of effectiveness for a given period of time of appearance of indoor expression TV is good.
