Outdoor Dual basic colors/monochrome display system is special for the use at various types of outdoor public places (the bulletins or ads at plazas, expressways, sportsgrounds, bus stations, residential quarters, etc). It adopts distributed scan and modularize design to improve the stability and dependability of the system. The display board specifications have many degrees of displaying density and many types of pixel tube including PH10, PH14, PH16, PH20, PH25 and PH31.5 (highway display board). Each luminous point has 256 grades of gray scale for red and green respectively, which constitute 65536 colors.
