Abstract

본 발명은 화상 표시장치에 관한 것으로, 픽셀(pixel) 단위로 화상이 표시되는 단판식 평판 패널(평판 표시소자)을 이용한 화상 투사 표시 장치의 화질을 향상시킬 수 있도록 하는 화상의 분할과 쉬프트(shift)기술에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image display apparatus, and more particularly, to an image display apparatus, which is capable of improving the image quality of an image projection display apparatus using a single plate type flat panel (flat panel display element) ) Technology.

종래의 화상 투사 표시장치는 다면 평판이나 다면 프리즘을 이용해서 파면 분할법으로 화상의 분할과 쉬프트를 수행하여 격벽을 제거한 화상이 스크린에 결상되도록 하고 있다.The conventional image projection display device divides and shifts an image by a wavefront division method using a multi-faceted flat plate or a multi-faceted prism so that an image obtained by removing a partition wall is formed on a screen.

그러므로, 다면 광학소자의 면 경계부위에서 발생하는 산란광에 의한 화질의 저하가 초래 되었으며 다면 광학 소자의 제작이 어렵고, 다면 광학 소자가 렌즈게에 종속되어 설계를 어렵게 하였다.Therefore, the image quality is degraded due to the scattering light generated on the surface boundary of the multi-layer optical element, and it is difficult to manufacture the multi-layer optical element and the multi-layer optical element is dependent on the lens gate.

본 발명은 평판 패널에서 출력된 화상 이미지의 광을 평판의 복굴절판을 이용해서 진폭분할법으로 2개로 분할하고 그중 하나의 광을 임의의 방향으로 적절하게 이동시켜 원화소를 복제한 화소를 원화소와 독립된 위치에 독립하여 투사함으로써, 원화소와 복제된 화소가 화상을 표시하게 되여 화상 관측시 실질적으로 관측되는 화소를 배가시킬 수 있도록 하며, 산란광에 의한 화질의 저하를 근본적으로 제거하고 또한 평판 광학 소자 채용으로 제작과 설계를 용이하게 한 화상 투사 표시장치를 제공한다.The present invention relates to a method and apparatus for dividing a light image of an image output from a flat panel into two by amplitude division using a planar birefringent plate, moving one of the light appropriately in an arbitrary direction, The pixels that are replicated with the original pixels display an image so that the pixels substantially observed at the time of image observation can be doubled and the deterioration of the image quality due to the scattered light can be fundamentally eliminated, An image projection display device that facilitates fabrication and design with adoption.
