The company supplies products: indoor full color led display material specifications are P4, P5, P6, P7.62, P8, P10; outdoor full-color LED display material specifications are P10, P12, P16, P20, P25, P31. 25. The basic structure of LED display systems display systems can be combined by a number of mosaic display unit constitute Screen, together with an appropriate controller. So a variety of display panels with different control technology controller can be composed of many types of LED display, to meet the different environments (indoor and outdoor), different display requirements. The main part of the display unit board --- display by led lights, light board and driver circuit. Indoor screen is a variety of unit display panels, outdoor screen is each individual unit box. Scan mode has a static display board, 1 / 2,1 / 4,1 / 8,1 / 16 other five. LED display unit board is one of the core components, unit board will directly influence the display effect. Unit board quality primary care core, so that the purchase of a full-color display, when the die selection is the most important, accounting for the largest share of the project cost in the entire display. Here to talk about the first focused on the display unit panel LED die LED die brightness will directly affect the brightness of the display. If you choose to die bright enough when making the display brightness by increasing the current increase, the direct impact on the life of the display. Therefore, in the production of the display, you should select the brightness higher than the brightness of the display requirements, but can not increase the current in order to improve the brightness, remember! Another point is the uniformity of the die, directly affect the uniformity of the display, including brightness uniformity wavelength uniformity and homogeneity. When the general selection die wavelength deviation 5nm, brightness variation less than 10% will not affect the display effect, beyond this range it will affect the display effect. LED driver chips include: constant current drive and constant voltage drive. Constant current constant current drive, maximum protection from damage LED constant current driver chips typically used in Taiwan accumulated MBI5026, MBI5024, Taiwan point crystal DM13A, Japan's Toshiba TB62726, reliable quality. And the current constant current drive some domestic manufacturers of some chips, although lower prices, but the quality will have problems, so should not be optional. Currently on the market, good quality die Corey United States, Japan's Nichia, Toshiba; general quality Opto Taiwan, Taiwan's wafer source, the new century, Taiwan; China's Hangzhou Silan, Xiamen security, Dalian Road America and other well-known brands die manufacturers. LED die which is high-tech, different LED die manufacturers will be great differences in quality, they pay for. LED die is good or bad from the following comparison: brightness, consistency, failure rate, antistatic ability, attenuation characteristics, service life. The company accessories are based on the market's most stable parts, from the quality and cost considerations, the customer if not otherwise specified, we generally LED die with Taiwan wafer RGB pipe or Taiwan Opto red tube + pure Swaziland Green Chunlan die or star power with CHUANGLIAN, control systems at all levels of the system Linsn. All materials are tested after several years of the brand, so users can rest assured that use.
