Abstract

액정 표시 장치의 후방 광원 장치와 일반 조명 장치의 광원으로 사용될 수 있는 면 광원 장치로서, 가스방전 및 형광체 발광의 원리를 이용한 면 광원 장치가 개시되어 있다.As a surface light source device that can be used as a light source of a rear light source device of a liquid crystal display device and a general lighting device, a surface light source device using the principle of gas discharge and phosphor emission is disclosed.

표시 장치의 광원으로서는 균일하고 고휘도의 광원이 요구되지만, 전극의 설치 방식이나 방전 경로가 편향되게 형성되어 전체적으로 불균일한 광선 방출이 일어나며 전극이 쉽게 열화되는 문제가 있었다.Although a uniform and high brightness light source is required as a light source of the display device, there is a problem in that the electrode installation method and the discharge path are formed to be deflected so that uneven light emission occurs overall and the electrode is easily deteriorated.

이와같은 문제를 해결하기 위하여, 복수의 와이어 또는 그물망 형태의 제1전극과 박막층의 유전체를 절연시킨 제2전극을 사용하며, 유전층의 내측으로 형광막을 형성시키고, 주로 수은과 네온 가스를 포함하는 가스혼합물을 충전시켜 가스 방전과 형광체 발광의 원리를 이용하여 면 광원 장치를 구성하였다. 이에 의해 경량화되고 균일한 고휘도와 고효율을 나타내며 수명이 연장된 면 광원 장치가 달성되도록 하였다.In order to solve this problem, a plurality of wire or mesh type first electrodes and a second electrode insulated from the dielectric of the thin film layer are used, and a fluorescent film is formed inside the dielectric layer, and the gas mainly contains mercury and neon gas. The mixture was charged to construct a surface light source device using the principles of gas discharge and phosphor emission. As a result, a surface light source device having a light weight, uniform high brightness and high efficiency, and an extended lifetime is achieved.

이와 같은 면 광원 장치는 액정 표시 장치 등의 후방 광원 또는 일반 조명 장치로 사용될 수 있다.Such a surface light source device may be used as a rear light source or a general lighting device such as a liquid crystal display device.
