Sinolight outdoor LED display is designed to be used outdoor under complex weather and environment .We devise temperature control system which can balance the influence from bad weather and ensure our products working normally, In the control part we use super-scale FPGA and reach 1024-grade grey control. Through hardware Gamma 128-grade,software Gamma unlimited regulation, RGB 128-grade colour-match adjustment, luminosity intensity equilibrium calculation, blur control calculation ,intelligence control technology ,we achieve luminosity self-adjustment and white balance self-repair Sinolight outdoor display integrates photoelectron ,micro-electronics ,computer, information technology and mechanism technology ,special cabinet structure has the advantages of light weight ,easy assembly and idisassembly ,high stability ,and strong visibility
