Abstract

본 발명은 액정 공정과 같은 열처리 고정에 의한 두 판 사이의 스트레스를 최소화하여 궁극적인 대면적 평판 디스플레이를 제조하는 방법에 관한 것으로서, 그 특징은 대면적 평판 디스플레이 제조방법에 있어서, 지지용판과 평판 디스플레이의 상판과 하판을 이용하여 타일링할 때에 접착제를 부분적으로 도포하고, 나머지 부분은 충전제를 이용하는데에 있고, 그 다른 특징은 대면적 평탄 디스플레이 제조방법에 있어서, 충전시간을 단축하기 위해 접착제 도포 모양을 여러 개의 영역으로 나누어 도포하여 충전시간을 단축시키는데에 있으며, 그 또 다른 특징은 대면적 평판 디스플레이 제조방법에 있어서, 투과형일 때는 충전제가 광투과형이며 접착제와 같은 광학적 특성을 가지는 데에 있고, 그 또 다른 특징은 대면적 평판 디스플레이 제조방법에 있어서, 비투광형일때는 충전제가 광학적 접착제가 광학적 성질이 달라도 상관이 없는 평판 디스플레이 제조에서 지지용 판을 이용하고 상판과 하판을 접착제로 타일링에 의해 대면적화하는 공정 중 접착제와 상판과 하판 사이의 열적 스트레스를 줄이기 위한 방법으로 전면에 접착제를 도포하지 않고 일부만을 도포한 후 나머지 부분을 충전제로 충전하는 데에 있으므로, 본 발명은 열처리 공정에서 제품이 열에 의한 스트레스의 영향을 받아 제품이 열화되는 것을 방지하는 데에 그 효과가 있다.The present invention relates to a method for manufacturing an ultimate large area flat panel display by minimizing stress between two plates by heat treatment fixing such as a liquid crystal process, and the feature is a method for manufacturing a large area flat panel display, the support plate and the flat panel display The adhesive is partially applied when tiling using the upper and lower plates of the substrate, and the remaining portion is used for the filler. The other characteristic is the manufacturing method of the large-area flat display, in order to shorten the filling time. It is applied to shorten the filling time by dividing into several areas, and another feature of the manufacturing method of the large-area flat panel display, when the transmissive type, the filler is light transmissive and has optical properties such as adhesive. Another feature is the large area flat panel display manufacturing method. For example, in the case of non-transmissive type, the filler is thermally connected between the adhesive and the upper and lower plates during the process of using a support plate and tiling the upper and lower plates with an adhesive in a flat panel display manufacturing where the optical adhesive does not have different optical properties. In order to reduce stress, the present invention is to fill the remaining part with filler after applying only a part of the product without applying an adhesive to the front surface, and thus, the present invention prevents the product from being deteriorated by the influence of heat stress in the heat treatment process. It is effective in doing so.
