Abstract
본 발명은 표면의 거칠기가 우수한 고품질 Glass를 이용한 Projection Display( LCD Projection TV, DLP 등)Projection Reflection Mirror의 제조공법 개발에 관한 내용이다. The present invention relates to the development of a manufacturing method of a projection display mirror (LCD projection TV, DLP, etc.) using a high-quality glass with excellent surface roughness.
Description
본 발명은 Glass의 표면 품질을 대폭 개선한 Glass를 이용한 Projection Display에 사용되는 Reflection Mirror 개발에 관한 내용이다. 현재 Reflection Mirror에 사용중인 Glass원판은 표면의 거칠기가 SPa(Non filtering data)=0.07~0.34micro 수준이며 이에 따라서 DLP와 같은 고화질 Display의 경우 화면의 왜곡을 발생시킨다. 본 발명은 Glass의 표면의 거칠기를 SPa=0.05micro이하의 Glass를 이용하여 Reflection Mirror를 형성하는 것이다. The present invention relates to the development of a reflection mirror used in a projection display using glass which has greatly improved the surface quality of glass. Currently, the glass original plate used for reflection mirror has surface roughness of SPa (Non filtering data) = 0.07 ~ 0.34micro, which causes distortion of high-definition display such as DLP. The present invention is to form a reflection mirror using the glass roughness of the surface of the glass using SPa = 0.05 micrometer or less.
본 발명이 이루고저하는 기술적인 과제는 다음과 같다. Technical problems to be solved by the present invention are as follows.
다음 그림은 현재 Projection Mirror에 사용중인 Glass원판의 표면 거칠기를 나타낸 것이다. The following figure shows the surface roughness of the original glass plate used for the projection mirror.

본 발명은 위의 그림에서와 같이 표면의 거칠기가 SPa (Non Filtering) 0.05micro이하이며 20x20 mm2의 면적에서 Glass의 굴곡이 존재하지 않는 Glass를 사용하는 것이다.In the present invention, as shown in the above figure, the surface roughness is less than 0.05 microns of SPa (Non Filtering), and the glass does not exist in the area of 20x20 mm2.
본 발명은 위 그림 2의 표면 품질을 지닌 Glass를 이용하여 Projection Mirror를 만드는 방법이다.다음 그림은 Prjection Mirror(52inch)의 구조를 나타낸 것이다. The present invention is a method of making a projection mirror using the glass having the surface quality of Figure 2. The following figure shows the structure of the Prjection Mirror (52 inch).
