FAQ
- How do I choose the dot pitch of the LED display?
- Uses: Widely used in railway, civil aviation, sports venues, conference halls, highways, squares, large shopping malls, banks, securities markets and a variety of transportation, water conservancy, electricity monitoring and control.
- What is the thickness of the led display?
- Full-color screen 150-180mm, monochrome will be smaller, 60-90
- 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 a board dark light how is it?
- Visual power cable, unit board between the 26P cable and power module indicator light is normal. The following are the same as the "
- Led display brightness is not enough because of what are the reasons
- If the screen is a very small piece of time is sometimes very dark, the unit is usually a problem, or drive IC problems, to replace. If the entire LED screen has become very dark, if the circuit board control system problems, it is recommended to restore the factory mode. If it is caused by the graphics driver, it is recommended to update or reinstall the driver.
- 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)
- Comparison between LED display and DLP splicing
- LED display is an advanced digital information products, it successfully combines the computer technology, network communication technology, image processing technology, embedded control technology, with a flexible display area and resolution (modular can be arbitrarily assembled),
- LED display power can not be displayed properly
- If the display interface definition does not match the provided HUB board, a black screen will appear. Please check if there is a loose, open or short circuit in your jumper. If you have the ABCD and other signals one by one correspondence, please check the OE signal is connected correctly.
