What are the Necessary LED Screen Components?

1.LED lights and chips

LED Lamp is a key component of the LED display panel. It is necessary to use LED products with reliable quality and mature packaging. The selected LED products must have good stability, small dispersion, HBM greater than 4000V, small attenuation amplitude, strong withstand voltage, high brightness, wavelength, and angle consistency, good light distribution effect, and resistance to temperature difference, humidity and ultraviolet rays.

3. Switching power supply
The power supply of the display screen adopts the certified switching power supply module of the famous brand.The power supply must undergo strict testing, screening and aging.Ensure that it fully meets the requirements of international safety and quality certification to meet the requirements of long-term stable and reliable operation of the display screen.

5, Control card

LED control card, also known as LED display controller, can receive image and video signals from computer, and then be responsible for showing the information it receives on the display
Synchronous LED Control System : enable the display to show real-time contents of the controlled computer. Asynchronous LED Control System : you can first edit the content on the computer and then send it to the receiving board.
(1) The asynchronous system mainly controls the screen via WIFI / 4G, but you can also control the screen via computer.
(2) One of the most obvious differences is that you cannot play the real-time content through asynchronous control system.
(3) If the total pixel count is less than 230W, both control systems can be chosen. However, if the number is greater than 230W, it is recommended that you can only select Syn control method.
The commonly used brands in the Chinese market are Novastar , Colorlight, HDplayer, Linsn, C-power, etc..

7.Driver IC device

When purchasing LED display accessories driver chip ic device, the driver circuit should choose the constant current driver chip of international famous brand. In a wide temperature range, maintaining high-precision constant current output and high reliability can significantly improve the uniformity and reliability of the display.For smooth functioning of the entire LED system, choosing quality LED display parts holds a lot of importance.
Main materials of the display system should be certified by CE, FCC, UL, CCC, ISO9000, etc.
The reliable supporting facilities materials and professional R & D design technology, will be able to reduce the failure rate of the display, and will greatly improve the reliability and stability of the LED display.
