Abstract
Description
본 발명은 LCD 백라이터용 평판 형광 램프로서 평면상에 균일한 휘도와 박형을 목적으로 한다. 즉, 종래의 평판램프에서 상하판 사이의 공간을 유지하기 위한 기둥의 역할을 하는 스페이서를 형광관으로 대처하여 자체 발광하는 격벽의 역할을 하도록 고안하여 휘도의 균일성과 제작의 간편함을 목적으로 고안되었다.The present invention is a flat fluorescent lamp for LCD backlighting, which aims at uniform brightness and thinness on a flat surface. That is, it was designed for the uniformity of luminance and simplicity of production by devising a role of a partition wall that emits light by coping with a spacer that serves as a pillar for maintaining a space between upper and lower plates in a conventional flat lamp with a fluorescent tube. .
액정디스플레이(Liquid Crystal Display; LCD)의 광원으로 사용되는 소위 LCD-백라이터로서 평판 형광 램프가 개발되고 있다. 이러한 평판램프는 면적이 작은 경우는 스페이서를 설치하지 않는 대신에 상하판 유리의 두껍게 한다. 그러나 평판램프의 면적이 커지면 상하판을 지지하기 위한 기둥의 역할을 하는 스페이서의 사용이 불가피하다. 이러한 경우 스페이서를 사용하지 않으면 램프의 내부 압력과 외부 압력의 차이로 상하판 유리가 파손된다. 이러한 스페이서는 구술형이나 삼각대 및 십자형 등이 사용되고 있다. 그러나 스페이서를 사용하더라도 유리 두께를 충분히 확보하지 않으면 유리가 파손되는 문제점이 있다. 결과적으로 평판램프가 두꺼워지고 무겁게된다. 스페이서의 용도와 함께 상판이나 하판에 격벽을 설치할 수도 있다. 그러나 이러한 경우는 격벽 부근의 휘도 저하로 격벽의 줄무늬가 평판에 나타나서 균일한 휘도를 얻을 수 없다.Flat fluorescent lamps have been developed as so-called LCD-backers used as light sources for liquid crystal displays (LCDs). When the flat lamp is small in area, the upper and lower glass plates are thickened instead of providing spacers. However, when the area of the flat lamp increases, it is inevitable to use a spacer that serves as a pillar for supporting the upper and lower plates. In this case, if the spacer is not used, the upper and lower glass are broken by the difference between the internal pressure and the external pressure of the lamp. Such spacers are dictated, tripod and cross. However, even when using a spacer there is a problem that the glass is broken if the glass thickness is not sufficiently secured. As a result, the flat lamp becomes thicker and heavier. In addition to the use of the spacer, partition walls may be provided on the upper and lower plates. However, in such a case, the stripe of the partition appears on the flat plate due to the decrease in luminance near the partition, so that uniform brightness cannot be obtained.
본 발명은 박형 구조를 갖는 평판 형광램프이다. 종래의 평판램프에서 사용하는 구슬형 등의 스페이서를 대신하여 길고 직경이 작은 다수의 형광관을 상판과 하판 사이에 일정한 간격으로 배치하여 발광하는 격벽의 역할을 한다. 평판램프를 위하여 상하판에 형광체를 도포하고 실린더형 내부에 형광체가 도포된 형광관을 격벽으로 사용하기 때문에 제작상의 별도의 기술이 요구되지 않는다.The present invention is a flat fluorescent lamp having a thin structure. Instead of a spacer such as a beads used in a conventional flat lamp, a large number of small fluorescent tubes are disposed at regular intervals between the upper plate and the lower plate to serve as a partition wall for emitting light. Since the fluorescent material is coated on the upper and lower plates for the flat lamp and the fluorescent tube coated with the fluorescent material is used as the partition wall, no separate technology is required for manufacturing.

본 발명은 액정 디스플레이(LCD; Liquid Crystal Display) 장치의 고 휘도의 LCD-백라이터를 위한 발광하는 격벽구조를 갖는 평판램프이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention is a flat lamp having a light emitting partition structure for a high brightness LCD backlight of a liquid crystal display (LCD) device.
도 1은 형광관을 격벽으로 사용한 평판형광램프의 개념도로서 상판과 하판의 분리된 사시도이다. 상판(1)과 하판(2) 사이에 다수의 형광관(3)을 일정한 간격으로 배치하여 평판램프의 격벽과 지지대 역할을 한다. 상판과 하판에는 각각 형광체가 도포된다(4, 5). 실린더형의 형광관 내부에도 형광체(7)가 도포된다. 본 발명에서의 전극 구조는 여러 가지를 채용할 수 있다. 일반적으로 균일한 방전을 위하여 전도성 재료의 전극을 유전체를 도포한 교류형 방전을 채용한다. 이러한 전극에 대한 형태는 본 발명의 사항이 아니므로 그림에 나타내지 않았다. 일반적인 평판램프와 마찬가지로 평판의 가장자리에 봉합대(6)를 설치하고 상하판을 부착한다.1 is a conceptual view of a flat fluorescent lamp using a fluorescent tube as a partition wall, and is a separated perspective view of an upper plate and a lower plate. A plurality of fluorescent tubes 3 are arranged at regular intervals between the upper plate 1 and the lower plate 2 to serve as partition walls and supports of the flat lamp. Phosphors are applied to the upper and lower plates, respectively (4, 5). The phosphor 7 is also applied inside the cylindrical fluorescent tube. The electrode structure in this invention can employ | adopt various. In general, an alternating current type discharge in which a dielectric is applied to an electrode of a conductive material is employed for uniform discharge. The shape of such an electrode is not shown in the figure because it is not a matter of the present invention. Like a general flat lamp, the suture bar 6 is installed at the edge of the flat plate and the upper and lower plates are attached.
도 2는 형광관을 격벽으로 채용한 평판램프의 상하판이 결합된 가로축 방향의 단면도이다. 상하판 사이에 일정한 간격으로 형광관이 배치되었다. 이들은 상하의 형광판을 지지하는 기둥의 역할과 방전공간을 분리하는 격벽의 기능을 한다. 또한 상하판의 형광판의 발광과 동시에 격벽 형광관 자체도 발광하므로서 휘도의 균일도를 얻는다.2 is a cross-sectional view in a horizontal axis direction in which upper and lower plates of a flat lamp employing a fluorescent tube as a partition wall are coupled. Fluorescent tubes were arranged at regular intervals between the upper and lower plates. They function as pillars for supporting the upper and lower fluorescent plates and as partition walls for separating discharge spaces. In addition, simultaneously with the emission of the upper and lower fluorescent plates, the partition fluorescent tubes themselves emit light, thereby obtaining uniformity in luminance.
본 발명은 LCD의 대화면용 고휘도의 백라이터의 용도에 적합하다. 대면적 평판램프에서 스페이서의 문제를 해결하여 가볍고 박형의 평판램프가 실현된다. 종래의 스페이서의 설치로 인한 제작상의 어려움을 피할 수 있다. 또한 격벽으로 분리된 방전 공간에서 균일한 플라즈마가 생성되고 격벽인 형관관 자체가 발광하므로 휘도의 균일도를 얻을 수 있다.The present invention is suitable for the use of a high-brightness backlighter for a large screen of an LCD. Light and thin flat lamps are realized by solving the problem of spacer in large area flat lamps. Manufacturing difficulties due to the installation of a conventional spacer can be avoided. In addition, since a uniform plasma is generated in the discharge space separated by the partition wall and the pipe tube itself as the partition wall emits light, uniformity of luminance can be obtained.
