P4 full color LED large screen installation Zweig Shenzhen Optoelectronic Technology Co., Ltd. was established in July 2013, is located: Shenzhen Bao'an District, paddy field community Jie Jia Po 21. Zweig photoelectric is a research, production, marketing, project implementation and after-sales service for the integrated enterprise, is one of the largest providers of LED products application system solutions currently. The company products include: LED outdoor full color display, LED indoor full color display, LED brick screen, LED bus screen, LED traffic screen, LED color screen, LED rental display, LED advertising screen high-definition, LED high-definition dot pitch screen, LED indoor screen, outdoor billboards, DLP laser fusion screen, LED display application development, indoor appearance of stickers and other products. Shenzhen Zweig photoelectric indoor look sticker Advantages 1, loss of efficiency due to the full-color display by a group of thousands or even hundreds of thousands of red, green, and blue LED pixels composed of dots, any color LED failure will affect monitor the overall visual effect. In general, according to industry experience in LED display will begin to assemble the failure rate of aging 72 hours before shipment should not exceed ten thousandths (of a failure of the LED device itself causes). 2, the antistatic ability LED is a semiconductor device, sensitive to static electricity, caused by static electricity can easily fail, it is essential to monitor the life of antistatic ability. Generally speaking, LED's body static mode test failure voltage of not less than 2000V. 3, the attenuation characteristics of red, green and blue LED have increased working hours with the brightness attenuation characteristics. LED chip's strengths and weaknesses, the quality and level of packaging technology auxiliary material determines the LED decay rate. Typically, 1000 hours, 20 mA at room temperature after the lighting test, the red LED attenuation should be less than 10%, blue, green LED attenuation should be less than 15% of red, green and blue attenuation consistency full-color LED display the future impact of large white balance screen, and then display fidelity affect the display. 4. Brightness LED brightness is an important determinant of the display's brightness. LED brightness higher, the greater use of current margin of power savings, keeping LED stable good. LED has a different angle, the brightness has been set in the chip case, the smaller the angle, LED is the light, but the viewing angle of the display is smaller. General should be chosen to ensure that the 100-degree LED display sufficient perspective. Different for different point spacing and line of sight of the display, you should find a balance in brightness, angle and prices. 5. Consistency full-color display is composed of numerous pixels of red, green and blue LED composed spell, each color LED brightness, wavelength determines the consistency of the entire screen brightness uniformity, consistency balance , color consistency. Generally, display devices require manufacturers and suppliers to provide 1 5nm wavelength range: the range of 1.3 brightness LED, these indicators can be component suppliers were graded by color separation machine reach. Voltage is generally not required consistency.
