With the continuous development of LED display industry, LED display products by the public will become increasingly familiar with, LED display diy also will become the mainstream of the entire industry. Do clear division of labor between the user and the LED display manufacturer. LED display manufacturers responsible for the development, production of semi-finished products needed for LED display LED display modules and LED unit board modules, such as, the user can follow through the line like the size of any LED display DIY. LED display DIY coming era will bring the whole industry a new round of explosive growth. We often encounter LED unit board module does not light situations Jiangsu led unit board, packaging companies, application companies as well as units and individuals use Hefei led unit board, are likely to encounter, and this is within the industry says dead lights phenomenon. Since LED lamp beads are semiconductor devices sensitive to static electricity, static electricity can easily lead to failure of Linyi led unit board, it is essential antistatic ability of the LED display life. In general, LED lamp beads body static mode test failure voltage of not less than 2000V. With increasing brightness LED lamp beads time will slowly decay. Decay rate of LED chip, auxiliary materials, packaging technology LED lamp brightness has some relevance. Generally led unit board, 1000 hours, 20 mA at room temperature after the lighting test, the red LED lamp beads attenuation should be less than 7%, blue, green LED lamp beads attenuation should be less than 10% of red, green, blue decay consistent effect on full-color LED display future great balance, and then show fidelity affect the display.
