Five full-color LED display elements:
   1.the full-color display by a group of thousands or even hundreds of thousands of red, green, and blue LED pixels composed of dots, the failure of any color LED display 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).
   2.LED is a semiconductor device, sensitive to static electricity, caused by static electricity can easily fail, it is essential for the life of the display antistatic ability. Generally speaking, LED's body static mode test failure voltage of not less than 2000V.
   3.the attenuation characteristic
   Red, green and blue LED have working time and increases brightness decay 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, the brightness of each color LED, the wavelength of consistency determines the entire screen brightness uniformity, consistency of white balance, color consistency sex. 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.
Since the LED is angled, so full-color LED display also has a directional point of view, that when viewed at different angles, its brightness is incremented or decremented. Thus, the red, green, and blue LED angle consistency will seriously affect the consistency of different angles, white balance, directly affecting the display of video color fidelity. To do the red, green and blue LED brightness variations at different angles to match the consistency, we need to package the lens design, raw material selection on strict scientific design, depending on package vendor technology. No matter how good the display method in the direction of balance, consistency is not good if the angle of LED, the entire screen white balance effect different angles will be bad. Consistency characteristic angle LED devices available LED Tester angle measured for the high-end display is particularly important.
