Features and Benefits Contro circuit and RGB chip are integrated in a package of 5050 components, form a compete contro of pixe point. Buit-in signa reshaping circuit, after wave reshaping to the next driver, ensure wave-form distortion not accumuate. Buit-in eectric reset circuit and power ost reset circuit. Each pixe of the three primary coor can achieve 256 brightness dispay, competed 16777216 coor fu coor dispay, and scan frequency not ess than 400Hz/s. Cascading port transmission signa by singe ine. Any two point the distance more than 5m transmission signa without any increase circuit. When the refresh rate is 30fps, ow speed mode cascade number are not ess than 512 points, high speed mode not ess than1024 points. Send data at speeds of 800Kbps. The coor of the ight were highy consistent, cost-effective.. Appications Fu-coor modue, Fu coor soft ights a amp strip. LED decorative ighting, Indoor/outdoor LED video irreguar screen. Genera description is a inteigent contro LED ight source that the contro circuit and RGB chip are integrated in a package of 5050 components. It interna incude inteigent digita port data atch and signa reshaping ampif ication drive circuit. Aso incude a precision interna osciator and a 12 votage programmabe constant curre -nt contro part, effectivey ensuring the pixe point ight coor height consistent. The data transfer protoco use singe NZR communication mode. After the pixe power-on reset, the DIN port receive data from controer, the first pixe coect initia 24bit data then sent to the interna data atch, the other data which reshaping by the interna signa reshaping ampification circuit sent to the next cascade pixe through the DO port. After transmission for each pixe,the signa to reduce 24bit. pixe adopt auto resha -ping transmit technoogy, making the pixe cascade number is not imited the signa transmission, ony depend on the speed of signa transmission. LED with ow driving votage, environmenta protection and energy saving, high brightness, scattering ang e is arge, good consistency, ow power, ong ife and other advantages. The contro chip integrated in LED above becoming more simpe circuit, sma voume, convenient instaation.
