The maximum brightness of the LCD display, usually by a cold cathode ray tube (backlight) to determine Zhijiang full color led display, brightness values ??are generally in the 200 ~ 250 cd / m2 room. LCD brightness is slightly lower, you will feel the screen dark. Through years of experience Zhijiang full color led display, LCD monitors on the market today brightness generally are 250cd / m2, more than 24 inches of the display will have a slightly higher Zhijiang full color led display, but will remain at 300 ~ 400 cd / m2 Rooms, though technically possible to achieve higher brightness, but that does not mean luminance value as high as possible, because high brightness of the display has the potential to hurt the viewer's eyes Specifically, LED junction temperature is due to two factors caused by: 1. Internal quantum efficiency is not high, that is, when electrons and holes recombine and generate a photon can not be 100% of Zhijiang full color led display, commonly referred to as the "current leakage" leaving the PN zone carrier recombination rate decreases. Leakage current times voltage is this part of the power, which is converted into heat, but this part does not account for the main component, because the internal photon efficiency is close to 90%. led display _ 金锐光 electricity (Online) _ Zhijiang led display provided by Yichang Technology Co. 金锐光.
