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 brightness is not enough because of what are the reasons: Note: The above is the common cause of the LED screen dark screen, starting from the basic situation, one by one investigation, if the above can not solve your problem, please contact the warranty.

Q:LED display screen appears black? How to solve?: Of course, the above is basically caused by the hardware, then the software is the most likely is the computer suddenly poisoned, the solution is to financial security mode, and then a full anti-virus on the computer, and then use 360 security guards to repair the system

Q:Production of LED display the basic raw materials which ah?: Circuit board, light-emitting diode, 138,245D, 4953, driver IC, capacitor, resistance, mask, bottom shell, bracket, magnetic column, waterproof glue, waterproof pad, pin, cable, power cord, power supply , Box, steel structure, control system (synchronous receiving card, send card, adapter board; asynchronous card)

Q:Comparison between LED display and DLP splicing: LED is a light-emitting diode, is a solid-state semiconductor devices, it can be directly into the energy of light energy.

Q:16: 9LED What is the approximate size of the display?: Ie the effective screen is the diagonal size representation. And the aspect ratio of 16: 9 is that we say widescreen, the unit is inches. From this we can calculate the scale factor. (The old TV used in the ratio of 4: 3 also we said the narrow screen)

Q:LED outdoor display which part of the composition: Banking, securities markets, construction markets, auction houses, industrial enterprise management and other public places. With media display, information release, traffic guidance, creative display and other purposes.

Q:LED display applications are what: The development of modern information display technology, the formation of the CRT, LCD, PDP, LED, EL, DLP series of information display products, look at all kinds of display products, each have their own strengths and appropriate Market application requirements. With the LED material technology and technology to enhance the LED display to highlight the advantages of a flat panel display one of the mainstream products, and in many areas of social economy has been widely used,

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 electronic display and P have anything to do: The above-mentioned P4 indicates that the dot pitch is 4mm and P10 indicates that the pixel distance is 10mm. In addition, the best visual distance = point spacing / (0.3 ~ 0.8), for example, the dot pitch 16mm display, the best visual distance on this is 20 to 54 meters, the distance from the station closer to the nearest distance , And will be able to distinguish one of the pixels of the display, grainy stronger, stand far away, the human eye can not tell the details of the details.
