본 문서는 페이즈 컨트롤 백라이트를 구현하기 위한 기술 및 장치를 설명한다. 페이즈 컨트롤 백라이트는, 이미지가 뷰어의 각각의 눈동자에 디스플레이되게 하기 위해 디스플레이의 뷰어의 각각의 눈동자에 광을 집중시키도록 구성된다. 페이즈 컨트롤 백라이트는 조명기 및 회절 격자를 포함하는 광 가이드를 포함할 수 있다. 광 가이드는 조명기로부터 광선을 수신하도록, 그리고 회절 격자를 통해 광 가이드 밖으로 광선을 회절시키도록 구성된다. 다양한 실시형태에 따르면, 뷰어의 각각의 눈동자의 공간에서의 위치에 대응하는 집중점에 회절된 광선이 수렴하게 하기 위해, 광 가이드는 광선이 광 가이드 내부에서 가이드될 때 광선의 페이즈를 변경하도록 제어될 수 있다. This document describes techniques and apparatuses for implementing a phase control backlight. A phase control backlight is configured to concentrate light to each pupil of a viewer of a display to cause images to be displayed to each pupil of the viewer. The phase control backlight can include an illuminator and a light guide that includes a diffraction grating. The light guide is configured to receive light rays from the illuminator, and to diffract light rays out of the light guide via the diffraction grating. In accordance with various embodiments, the light guide can be controlled to alter a phase of the light rays as the light rays are guided within the light guide to cause the diffracted light rays to converge to a concentration point that corresponds to a position in space of each pupil of the viewer.
