LED display screen “dead pixels” (typically referring to issues such as non-illuminating, constantly lit, dimly lit, or color-shifted LED chips) are common problems. Therefore, we should first diagnose the LED display screen before taking appropriate measures.   I. Quickly Determine the Problem Type First, determine whether it’s a single damaged lamp or a regional issue: […]

GOB packaging technology is essentially SMD technology, but it reinforces and strengthens the SMD screen. A layer of special transparent epoxy resin is evenly applied to the surface of the assembled SMD module. After curing, this adhesive forms a high-hardness, high-transmittance protective layer that encapsulates all the LEDs, solder joints, and leads, creating a protective

The packaging technology used in COB screens is different from that of traditional SMD screens. SMD screen packaging process: this involves fixing LED chips inside a bracket cup, encapsulating them into individual LED beads, and then soldering the beads onto a PCB board. The surface has a grainy texture; each LED lamp is separate and
