Poor power supply or power supply has been aging: Many inferior computer power, could easily lead to poor computer circuit or power capacity to keep up led display control software, when the system is busy, the display screen will appear, especially the phenomenon of jitter. Also, if the computer's power supplies aging, it is likely to cause the same problem. Put too close to the speakers: the speaker magnetic field effect generated can interfere with the normal operation of the display, the display screen jitter generation and cross color and other magnetic interference. Caused by a virus: Some computer viruses will disrupt the screen display, for example: character upside down, shake the screen, flip the display graphics. Everywhere online screen jitter script full color led display, is enough to make you move after the head as big as a cow. Graphics Card Problem: closely monitor and graphics card, the computer screen can be considered a failure not because of graphics cards, such as: bad graphics. However, based on LED lamp shell radiating power size and the use of premises led display, there will be different options. There are the following cooling methods: aluminum fins: This is the most common cooling method, as part of the housing aluminum fins to increase the cooling area. Thermal plastic case: a thermally conductive material at the time of filling plastic injection molding, plastic housing increased thermal conductivity, heat capacity. Air hydrodynamics use of the lamp envelope shape, to create a convection air, which is the lowest-cost way to enhance heat dissipation. Fan lamp shell reinforced with long life and efficient internal cooling fan, low cost led display price and good effect. But some want to change the fan is in trouble, not suitable for outdoor, this design is more rare. The use of a heat exchanger tube heat exchanger tube technology, the heat conduction from the LED chip to the housing fins. In large lamps, such as street lamps is a common design. Surface radiation heat treatment lamp shell surface radiation heat treatment done, the simplest is to smear Hua Wei Sheng Zhi heat radiation paint, radiant heat mode can be removed from the surface of the lamp envelope.
