Impact display performance of several key parameters 1. Power. LED is a very energy-efficient light-emitting device. LED device determines the power consumption of the power consumption of LED full color display. 2. attenuation characteristics. There will be inconsistent with the display brightness down and after the phenomenon of color LED full color display to work long hours. 3. brightness. Brightness is the basic indicator LED full-color display. ② chromaticity consistency. Colors of the LED full color LED display device depends LED wavelength, wavelength range too wide, color differences will be larger, it will affect the display color consistency. In general, red, green, and blue color wavelength range each require less than 5nm. ③ angle consistency. LED full color display is composed of one angled LED devices composed of inconsistencies seriously affect the LED devices angle will be the display brightness, color consistency of different angles. LED devices (especially the oval light) red, green and blue luminance uniformity with viewing angle variation curve also seriously affect the display brightness at different angles, color consistency. All full-color display parameters, this parameter is an indicator of the most difficult to reach. High-low LED full color display major differences in this. 5. The failure rate. An important indicator LED full color display is LED blind spot rate, which depends entirely on the quality of LED devices (excluding display production process Weld, weld, poor contact and other effects). LED devices in the factory should be subject to various types of sample tests, including room temperature, lighting, temperature and humidity, thermal shock and other series of tests to ensure product stability, consistency and continuity. In general, for full-color display high-quality LED devices 1000 hours failure rate should be less than a million. 6. refresh rate. Refresh rate is an important indicator of the display is a display stability characterizing parameter higher the refresh rate, the more stable the display screen. Usually the display refresh rate 300HZ, with general camera does not appear scanning line; if asked to use a professional camera does not appear scanning line, 600HZ refresh rate requires more, many control systems can do more than 1000HZ. 7. Control system. Control systems are also an important part of the impact of the company LED display 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 Taiwan Opto red tube or pipe + Swaziland pure 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.
