Compared with the traditional LED display, LED projecting a small spacing feature is smaller dot pitch. In practice, the smaller the dot pitch, the higher the pixel density, suitable viewing distance is more recent, on the contrary, is suitable farther viewing distance. Small pitch LED screen in order to achieve the best visual effects, led unit board, has the best line of sight, the user can perform simple calculations, there is an established formula that best viewing distance = spacing /0.3~0.8 . The smaller the dot pitch, the higher the cost of a small pitch LED display, so the actual purchase, the monochrome led unit board, the user should consider their own cost, demand, application and other factors. For example: In order to meet the needs of the stage scene, the display needs to be moved in the live scene mosaic style. If staff negligence or other reasons, a large-screen display signal input line took place in the middle of release, in the conventional control scheme, the occurrence of loose housing from the beginning to the end of the signaling cascade, all display It will be no signal. If you add the hot backup program summary, p4 led unit board in the control system to improve the stability of the display from the material selection, the various aspects of Linyi led unit board, hardware design, system control programs, etc. into account. We need to have an experienced, powerful R & D team. p10 led unit board _led cell plate _ Gao Jin photoelectric provided by Jinan Optoelectronics Technology Co., Ltd. Gao Jin. Jinan Gao Jin Optoelectronics Technology Co., Ltd. (www.gjlled.cn) strong, credible, in Jinan, Shandong liquid crystal device industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Gao Jin photoelectric and you hand into the brilliant, for a better future!
