Abstract

액정 표시 장치의 후방 광원 또는 일반 조명용으로 사용되는 평판형 면 광원 장치가 개시되어 있다.Disclosed is a flat surface light source device used for a rear light source or general illumination of a liquid crystal display device.

이와 같은 광원 장치는 발광면이 전체적으로 균일한 광도를 갖는 것이 바람직하다. 균일한 광도를 얻으려면 기본적으로 방전이 균일하게 발생되도록 하는 것이 선결되어야할 요건이다.It is preferable that such a light source device has a uniform luminous intensity on the light emitting surface as a whole. In order to obtain uniform brightness, it is basically a requirement to make the discharge occur uniformly.

이를 위한 평판형 면 광원 장치는, 투명한 재료로 이루어지며 밀폐가능한 용기, 상기 밀폐 용기의 상판과 하판의 내부에 도포된 형광막, 좌우 양면의 내부에 전체 길이에 걸쳐 설치된 전극 또는 복수의 전극, 전극에 부착된 유전체, 밀폐 용기 내에 충진되는 회가스 및 수은 가스, 및 하판 외부에 형성되는 반사막을 포함하여 구성된다.A flat surface light source device for this purpose is a container made of a transparent material, a sealable container, a fluorescent film applied to the inside of the top and bottom of the sealed container, an electrode or a plurality of electrodes installed over the entire length inside the left and right sides, the electrode And a dielectric film attached to the ash, ash gas and mercury gas filled in the sealed container, and a reflective film formed on the outside of the lower plate.

이와 같은 면 광원 장치는 주로 액정 표시 장치의 후방 광원으로 사용된다.Such a surface light source device is mainly used as a rear light source of the liquid crystal display device.
