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パッケージング技術は基本的にSMD技術であるが、SMDスクリーンを補強・強化する。特殊な透明エポキシ樹脂の層が、組み立てられたSMDモジュールの表面に均一に塗布される。硬化後、この接着剤は高硬度、高透過率の保護層を形成し、すべてのLED、はんだ接合部、リード線を包み込み、保護膜を形成する。
