Specifically, led electronic display, LED junction temperature is due to two factors caused by: 1. Internal quantum efficiency is not high Yidu led electronic display, which is when the electrons and holes recombine and generate photons are not 100%, often referred to as the "leakage current" PN area leaving the carrier recombination rate decreases. Leakage current multiplied by voltage is power in this section when the sun led electronic display, which is converted into heat, but this part does not account for the main component, because the internal photon efficiency is close to 90%. To keep the humidity in general humidity between 30% to 80%, the display can work, but once the indoor humidity above 80%, it will produce condensation inside the monitor. Its internal power transformers and other coils are also easy to produce leakage after wet, and even may cause a short circuit wiring; and the high-pressure part of the display is easy to produce discharges; machine components susceptible to rust, corrosion, serious cause circuit short-circuit plate. Therefore, LCD monitors must pay attention to moisture, long time do not monitor, power work regularly for some time, so that the heat generated when the monitor is working to drive out the moisture inside the machine.
