Abstract

본 발명은 액정표시장치 모듈의 백라이트로 사용되는 LED 판넬에 관한 것으로서, 사각틀채 형상의 샤시하부에 PCB가 구비되고 상기 샤시 상부에 확산판과 구비되며, 상기 샤시 내부 측벽과 상기 PCB 상부에 반사판을 형성하되 상기 PCB 상부의 반사판은 요철 형상이 구비되고 상기 요철 형상의 반사판의 요부에 LED가 구비되어 고아의 난반사를 증가시켜 상기 LED가 형성되지 않은 부분의 상측과 상기 LED가 형성되는 부분의 상측 즉 저휘도를 갖는 부분과 고휘도를 갖는 부분의 휘도차이가 감소됨으로써 균일한 휘도가 유지되어 LCD모듈의 공정수율 및 소자동작의 신뢰성을 향상시킬 수 있는 잇점이 있다.The present invention relates to an LED panel used as a backlight of a liquid crystal display module, wherein a PCB is provided at a lower portion of a chassis having a rectangular frame shape, and is provided with a diffusion plate on the chassis, and a reflection plate is provided on the chassis inner sidewall and the PCB. The reflecting plate formed on the upper part of the PCB is provided with an uneven shape and an LED is provided on the recessed part of the uneven shape reflecting plate to increase the diffuse reflection of the orphan, so Since the luminance difference between the low luminance portion and the high luminance portion is reduced, uniform luminance is maintained, thereby improving process yield and reliability of device operation of the LCD module.
