Abstract: High Resolution Image Download MS PowerPoint Slide Light-field 3D display by super-multiviews is considered as a practical strategy to realize true 3D displays with enhanced depth cues. However, the limited space-bandwidth products pose challenges in providing an adequate number of viewpoints, while keeping a high 3D resolution. In this paper, a general strategy of “dual-view groups” is introduced into a super-multiview display, which provides 3D scenes efficiently to the binocular position. Specifically, we adopt the metagratings to modulate incident light into a dual-view group radiation pattern. Each view group is composed of super-multiviews with an angular interval of 0.45°. Such a narrow angular interval ensures that a single eye can receive multiple views simultaneously. Furthermore, by combining a multidirectional backlight module, a 15.6 in. metagrating matrix, and an LCD display, we experimentally demonstrated the proposed dual-view groups super-multiview (DVG-SMV) display can provide 3D images with correct depth cues and smooth motion parallax. The information density reaches 860.5 ppd (pixel per degree). The proposed DVG-SMV display exhibits the advantages of improved information density and accurate depth cues, which make it suitable for personal consumer electronics such as personal computers, tablets, and other applications.
