The LED module is to arrange the LED (light emitting diode) together according to a certain rule and then encapsulate it, plus some waterproof treatment products, that is, the LED module. The front surface of the quadrilateral module may be provided with a decorative structure for blurring the splicing boundary of the module. LED module COB light source LED surface light source utility model from the visual and optical point of view, let the straight line form a short line of misalignment, using the linearity of the vision, the human eye can not take into account the misalignment when scanning from top to bottom (or moving in the left and right direction) Strips will inevitably form countless dislocations of discontinuous short line segments, thus completely eliminating the LED display mosaic phenomenon caused by the gap between the modules.
If the new screen is installed and powered on, it may be that the control card settings are not scanned correctly, or the cable is not inserted correctly (check the cable from the control card to the first board), and the wrong 5V power supply will also cause this problem.
Solution: 1. The heat dissipation of the LED display must be done. We must consider the heat dissipation of the LED display during engineering design. Yinhan Zhixian fully considers that the poor heat dissipation will cause the color difference of the LED display from the design point. problem. 2. First prepare the phosphor powder cake, and then paste the cake on the surface of the chip through the paste method to achieve LED packaging 3. When buying phosphors, we must choose famous brands, and we must make samples many times before making goods in batches. 4. AB glue solidifies and releases at 120-130 degrees/30-40 minutes. If it exceeds 150 degrees or it is baked for a long time, it will turn yellow.
There are too many factors that affect the price of LED displays, and this question cannot be answered correctly. Inquiry basically needs to set the following requirements in order to know the relatively reliable estimated price.
