Pixel of Microdisplay Having Integrated Catadioptric Light Extraction System

개구형 오목 반사경을 가지는 마이크로 디스플레이의 단위 화소가 제공된다. 광 추출부는 동일한 단결정 성장 공정을 이용하여 형성된 돌출부 및 벌크부를 가진다. 돌출부 상에는 개구형 오목 반사경이 형성되고, 중심부의 개방영역을 통해 발광체의 결정 성장이 이루어진다. 또한, 개구형 오목 반사경에서 반사된 광은 낮은 출사각을 가지고 외부로 배출된다.

description 개구형 오목 반사경을 가지는 마이크로 디스플레이의 단위 화소가 제공된다. 광 추출부는 동일한 단결정 성장 공정을 이용하여 형성된 돌출부 및 벌크부를 가진다. 돌출부 상에는 개구형 오목 반사경이 형성되고, 중심부의 개방영역을 통해 발광체의 결정 성장이 이루어진다. 또한, 개구형 오목 반사경에서 반사된 광은 낮은 출사각을 가지고 외부로 배출된다. Disclosed is a unit pixel of a microdisplay having a concave reflector with a center aperture. The light extractor has a protrusion and a bulk portion formed using the same epitaxial growth process. The concave reflector with a center aperture is formed on the protrusion, and epitaxial growth of the light-emitting body is made through the aperture concave reflector. In addition, the light rays reflected by the concave reflector with a center aperture has exit angles that are nearly perpendicular to the exit surface and are thus easily emitted to the outside.
