DIP stands for Dual In-line Package. Its most distinctive feature is that each red, green, and blue LED lamps is an independent, “bullet-shaped” component with two pins, which are soldered through holes on the PCB board, and then a pixel housing (mask) is placed over the LED lamp. It has a low pixel density and […]

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 封装技术本质上是 SMD 技术，但它加强和强化了 SMD 屏幕。在组装好的 SMD 模块表面均匀地涂上一层特殊的透明环氧树脂。固化后，这种粘合剂会形成一个高硬度、高透光率的保护层，将所有 LED、焊点和引线包裹起来，形成一个保护性的
