Quality full-color LED display lamp beads key --LED

With the current LED display technology continues to innovation and development, a variety of novel LED display have entered our lives, such as the current popular full-color LED display. In the composition of full-color LED display among the thousands per square meter will have LED lamp, the LED lamp beads will directly affect the quality of full-color LED display. Next we look at LED lamp beads relevant knowledge of it. Zhengzhou LED display LED lamp beads quality indicators at four aspects. The first is the full-color LED display brightness. Brightness full-color LED display is determined by the brightness of the LED lamp, LED lamp beads brightness if higher, then use the current margin will be greater, to save power, maintaining stable LED lamp beads will have a very Great benefits. LED lamp beads have different locations different angle, in the case where the chip is determined luminance, the smaller the angle, LED is more light, but viewing angle of the display will be smaller. Followed by the LED full color display attenuation characteristics. With increasing brightness LED lamp beads time will slowly decay. LED chip, auxiliary materials, packaging technology and other determines the brightness of the LED lamp beads decay rate. Generally speaking, one thousand hours twenty milliamps lit test room temperature, the red LED lamp beads attenuation should be less than seven percent, blue and green LED lamp beads attenuation should be less than one tenth. Red, green, Blue attenuation consistency full-color LED display in the future have a significant impact balance, thereby affecting the fidelity of the display screen. Once again, antistatic ability Henan LED display LED lamp beads is due semiconductor devices sensitive to static electricity, can easily lead to failure of the phenomenon of static electricity, so antistatic ability and life LED display is relevant. Finally, the failure rate of LED full color display LED display is formed by a group of thousands or even hundreds of thousands of red, green, and blue LED lamp components. Even if the failure rate of aging lamp beads can not be more than three days to one. LED lamp beads LED display is the most used parts, which to some extent will determine the full-color LED display performance and color saturation and sharpness, a direct impact on the evaluation of the client viewer on the LED display so if we must focus on the LED display LED lamp beads when you need to buy LED display various properties.
