Abstract
본 발명은 백라이트형 LCD의 신규한 도광판을 개시한다.The present invention discloses a novel light guide plate of a backlit LCD.
종래의 편판형 도광판은 광원측에서 멀어질수록 광량이 감소되어 균일한 휘도를 제공하지 못하는 문제가 있었다.The conventional plate-shaped light guide plate has a problem in that the amount of light decreases as it moves away from the light source side, thereby failing to provide uniform luminance.
본 발명에서는 도광판의 상부에 오목한 인입부를 형성하여 광선의 확산을 촉진함으로써 별도의 확산판 없이도 균일한 휘도를 제공하도록 하였다.In the present invention, a concave lead portion is formed on the light guide plate to promote diffusion of light, thereby providing uniform luminance without a separate diffuser plate.
