In the mixed light on, because of its three instrument chip design and structure, cell plate, so that the distance is very small chip body, 5.0 unit board, mixing light can be carried out in the same bracket cup, led the three chips different from ordinary in different led the wholesale unit board, in light of the poor performance mixed. In a closer look, then paste the screen there with good viewing. In contrast is due to its structure for the three and one, smd will be small, the result is to have a small area of ??luminous form, p4 cell plate, and with large black areas, its screen contrast is very high. Many causes of display pixels out of control, the most important reason is that "LED failure." LED main cause of failure can be divided into two aspects: First LED its poor quality; the second is to use improper methods. Through analysis we summarize the correspondence between the LED failure modes and between the two main reason. p5.0 unit board | Cell Board | Gao Jin photoelectric provided by Jinan Optoelectronics Technology Co., Ltd.
