BLACK GLUE LED DISPLAY SCREEN AND PROCESSING METHOD THEREFOR

摘要

A black glue LED display screen and a processing method therefor. The black glue LED display screen comprises a circuit board (10) and LED light-emitting chips (20) mounted on the surface of the circuit board (10), and further comprises a black glue layer (30) covering the surface of the circuit board (10). The seams of the LED light-emitting chips (20) are filled with the black glue layer (30), and the upper surface of the LED light-emitting chips (20) is flush with the black glue layer (30) to form a flat surface. According to the black glue LED display screen, the LED light-emitting chips (20) are protected by the black glue layer (30), the consistency in color on the surface of the spliced display screen is ensured, the black glue layer (30) is flush with the upper surface of the LED light-emitting chips (20) so that the visual angle of the display screen is expanded, a moiré pattern phenomenon is avoided, and the display effect of the LED display screen is improved.
