FAQ

Led display and led lighting What is the difference?

Application areas are different. Led display mainly in: government square, leisure square, bustling business center, advertising information release card, commercial street, railway station, sports venues (UNILUMIN Universiade) and so on. Led lighting is mainly home, mall, roads and other lighting

LED display power supply how to configure how many units with the plate is calculated.

According to the unit board power calculation, P10 monochrome in general 10 to 12 blocks, indoor monochrome 12, indoor color 6, full color, then ask the unit board manufacturers, a board of how much power. And then calculate their own bar.

What is the thickness of the led display?

The thickness of less than 75mm, with the aluminum. Can also be thinner but the material is not easy to find.

LED display more than the size of the area must be 380v

LED display itself only need low-voltage DC power supply, whether it is 380V or 220V need to go through the buck and rectifier, which is the screen does not matter. Whether it is to use 380V or 220V depends entirely on the load balance of the power grid considerations, which depends not only on the size of the display, but also on the local grid capacity. In general, LED is weak devices, even if the display area and then large, the total power is also less than where to go, so you can use 220V single-phase power supply, but the power supply cable cross-sectional area to be larger, but the power circuit Much simpler.

LED display screen appears black? How to solve?

see whether the motherboard was burned signs, the general motherboard above the capacitor above the fever and a little black charred situation, the motherboard may be burned the situation.
