대화면 액정 화상 투영기용 다층 배열 엘이디 광원 및 조명광학계 설계 = Optical Design of a Multilayer LED Array Light Source and Illumination Optics for a Large-Screen LC Projection Display System

다국어 초록 (Multilingual Abstract)

A double-layer LED array together with an illumination optical system is proposed as a possible light source for LC projection display systems for large screens, up to $8m{\times}6m$ (400 inches diagonal). The heat dissipation problem of the LED array is solved by arranging the LEDs in double layers, and thermal analysis shows its effectiveness. The light from the LEDs in the back layer can be transmitted through the front layer without significant loss by arranging the LEDs in non-overlapping positions in the two layers and inserting suitable microlenses between the two layers and holes in the first layer. Together with the double-layer LEDs, an illumination optical system is designed to illuminate liquid crystal panels with good uniformity and appropriate matching with the projection optics.
