The GOB is an LED display made using GOB (GLUE ON THE BOARD) technology. The GOB process is an innovative technology in the LED industry. It combines optical thermal conductive nanometer filling materials with LED light panels. After encapsulation and matte dual surface treatment, it achieves a matte effect on the surface of the LED display and enhances the performance of the LED display. Protective technology. This module has significant advantages and value in the application of indoor small-pitch LED displays.
