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

Upstairs are said that the P10, if you do not use the P10 it I tell you how to calculate the power of a board. Generally you take a lamp beads 0.02A to count, a board on the total lamp beads * 0.02, if the board is 4 sweep with the band / 4,8 sweep of the 8, the static is not removed to get a board of power

Q: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.

Q:LED display applications are what

Securities trading, financial information, airport flight dynamic information display, port, station passengers, sports venues information display, road traffic information display, dispatch command center information display.

Q: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.

Q: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. It is recommended to take professional maintenance to detect the next. Under normal circumstances the motherboard is burned fan will not go to the. User self-test under.

Q:How to identify the quality of led display quality

Control card is basically 99% of the led display manufacturers are outsourced, the industry is better that is the celebration, superstar, de Puda, Nova, Carter these are used in full-color display more Some, relatively stable stability is better.

Q:Production of LED display the basic raw materials which ah?

LED display (LED panel): LED is light emitting diode, LED abbreviation, referred to as LED. It is a kind of control by the semiconductor light-emitting diode display, the approximate look is by a lot of usually red light-emitting diodes, light off the light to show the characters. Used to display text, graphics, images, animation, market, video, video signals and other information display screen.

Q:IPS screen and LED screen difference

LED is the light-emitting diode, so the so-called LED screen is the concept of confusion, in fact, LCD panel with LED as a backlight, but also useful as a backlight CCFL, CCFL is cold cathode fluorescent tube,

Q:16: 9LED What is the approximate size of the display?

16: 9 is only a proportional form, the specific size to be determined according to the area of the display. You display 16 meters long, 9 meters high, is 16: 9 ratio; display length of 10 meters, 5.6 meters high, is also the ratio of 16: 9. So there is no specific size!

Q:LED display power can not be displayed properly

In the process of using the control system, the occasional LED display will encounter a black screen phenomenon. The same phenomenon may be caused by a variety of different reasons, even the process of blacking the screen will be due to different operations or because of different environments vary. For example, it may be a power of the moment is black, it may be black during the loading process, it may be black after the completion of the transmission and so on.
