Dandong HD LED electronic display LED outdoor electronic display Jinzhou, Yingkou, Fuxin outdoor LED large screen outdoor LED electronic screen high-definition display, Dandong, Jinzhou, Yingkou LED outdoor electronic display outdoor LED large screen HD Dandong, Fuxin outdoor display LED electronic display LED outdoor electronic display Jinzhou outdoor LED large screen display Yingkou, Fuxin outdoor display how to control and improve how LED full color display quality control and improve the quality of full-color LED display? What to reflect full-color LED display dedicated LED is an important indicator of quality? First LED devices as the most critical components of full-color LED display, for three reasons: First, LED full-color machine is used in the largest number of key components, will use the thousands to tens of thousands per square meter LED; secondly, LED is to determine the performance of the entire body of the optical display screen, the audience directly impact assessment display; again, LED display share in the overall cost of the largest proportion, ranging from 30% to 70%. LED selection is determined by more than 50% of the entire display quality. If you fail to choose a good LED, other components of the display can not compensate for even the best display quality defects. Reflecting the full-color LED electronic screen HD LED outdoor electronic display outdoor important indicator LED large screen LED outdoor display special quality are: First, the failure rate due to the full-color display by a group of thousands or even hundreds of thousands of red, green, blue three types of LED elements dots composed of any color LED display failures will affect 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). Second, 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. Third, 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 the auxiliary material packaging process determines the level of 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. Fourth, the brightness of the 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. Five full-color display consistency is composed of numerous red, green and blue LED composed of primitive spell, the brightness of each color LED, the wavelength of consistency determines the entire screen brightness uniformity, consistency balance sex, 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.
