Abstract

본 발명은 액정표시장치 모듈의 백라이트로 사용되는 LED 판넬에 관한 것으로서, LED 판넬은 LED들이 일정간격으로 탑재되어 있는 PCB와 확산필름을 사각 틀체형성의 샤시 양측면에 설치하고, 그 사이에 중간 확산판을 설치하며, 상기 중간 확산판에서 LED와 대응되는 위치인 고휘도 부분에는 흰색 도료막을 도포하고, LED들 사이의 공간인 저휘도 부분에는 홀을 형성하며, 샤시 내측의 공간을 투명한 실리콘층으로 메워 LED판넬을 형성하였으므로, 도료막과 투명 실리콘층 및 홀의 측벽에서 광이 난반사되고 홀에서는 광 투과가 용이하여 고휘도 부분과 저휘도 부분의 휘도차가 감소되어 균일한 휘도를 유지할 수 있어 LCD 판넬의 화면의 질을 개선할 수 있다.The present invention relates to an LED panel used as a backlight of a liquid crystal display module, wherein the LED panel is installed on both sides of the chassis of the rectangular frame forming the PCB and the diffusion film on which the LEDs are mounted at regular intervals, between the intermediate diffusion plate A white coating film is applied to the high brightness portion corresponding to the LED in the intermediate diffusion plate, a hole is formed in the low brightness portion between the LEDs, and the space inside the chassis is filled with a transparent silicon layer. Since the panel is formed, light is diffusely reflected from the paint film, the transparent silicon layer, and the sidewalls of the hole, and light is easily transmitted through the hole, so that the luminance difference between the high luminance portion and the low luminance portion is reduced to maintain uniform luminance. Can be improved.
