 Dawning DS802 LED Sending Card,D802 LED Receiving Card

Dawning LED Card are specialized in R&D, manufacture and marketing of embedded software and hardware which is applied in LED photoelectric display, lighting etc. Our own R&D produced fullcolor led control system has been widely used in stage background, industrial and mining enterprises, station and dock, large square, city traffic and other places that create considerable social and economic benefits.

With more and more LED screen widely used, ‘blurry screen’, ‘dirty screen’ such ‘can’t calibrate’ problems has become a bottleneck that directly reduce LED screen working life and increase practice cost as well as restrict the development of LED industry. With 3 years unremitting effort, Dawning successfully developed ‘luminance and chrominance correction system’. The led card ‘Online full-color LED screen luminance correction and color gamut optimization method’ has obtained national invention patent which can make 14bit pixel correction for LED chips luminance and wavelength attenuation. This has filled a blank of internal market and will completely improve current LED display screen effect as well as promote our production export capability.

All LED Controller comply with ROHS,CE,FCC certification. The correction function of Dalian Dawning R&D control system is a core technology in LED application. In LED planar display, luminance and color gamut double targets correction at present is an unsolved technology difficulty in domestic.
