Full Color Display White LED

Outdoor full color LED display supplier ^ "full color display | White LED" ^ Xi'an LED display Our LED display professional production quality assurance points 1) light emitting device I choose a solid color full-color LED. 2) IC I choose Toshiba's integrated circuit chip TB drive with a constant current, and ensure consistency Screen display. 3) taking into account the impact of all integrated circuit currents margin, but also must consider the climate and environment. Our choice of working environment temperature screening index of integrated circuits based in -30 ℃ to 60 ℃, and continued for 72 hours. 4) All IC powered through aging, to ensure the reliability of its products. Because until after the integrated circuit has a period of instability is not powered on, aging screening can make it through the period of instability, tested, and truly determine its advantages and disadvantages. 5) temperature storage can avoid aging IC bonding process problems. 6) Switching Power Supply a) Our selection of famous company's products. b) has excellent electrical properties; c) having excellent temperature characteristics; d) overvoltage, overload protection function; e) suddenly loses power, reenergizing no counter electromotive force of impact; f) have a good filtering; g) temperature index is -30 ℃ to 60 ℃. h) 7) drive module i) using Toshiba constant current source driver circuit; j) the circuit board, "three" Process; k) module temperature aging treatment process continued for 72 hours; 8) control system l) Screen drive control module uses segment; m) "three prevention" technology processing; n) the use of large-scale programmable gate array device to significantly reduce the number of components on the module, in order to improve reliability; o) module temperature Aging Process , ambient temperature 60 ℃ and continued for 72 hours. 9) Power electrical intelligent control p) power load balancing function; q) electric power soft-start and soft-shutdown control function; r) power anomaly, the system overload, power protection.
