Abstract

The invention provides an integrated-imaging double vision 3D (Three-Dimensional) display device based on polarization gratings. The integrated-imaging double vision 3D display device comprises a display screen for displaying a microimage array, a microlens array, the polarization grating I and the polarization grating II, wherein the display screen is positioned on the focal plane of the microlens array; the horizontal central axis and vertical central axis of the display screen are respectively and correspondingly aligned to those of the microlens array. The polarization grating I is closely attached with the display screen, and the polarization grating II is closely attached with the microlens array. By virtue of the polarization grating I, light passing through the polarization grating I becomes linear polarization lights with different polarization directions, the polarization grating II has a modulation effect for the linear polarization lights, sub-image elements in two sub-microimage arrays rebuild 3D scenes to the left side or right side of the integrated-imaging image display equipment by lens elements corresponding to the sub-image elements, so that integrated-imaging double vision 3D display is realized.

Description

technical field [0001] The present invention relates to a dual-view 3D display, and more specifically, the present invention relates to an integrated imaging dual-view 3D display device based on a polarization grating. Background technique [0002] Dual-view display is a new type of display that has emerged in recent years. Its principle is to display two different pictures on a display screen at the same time, and viewers in different viewing directions can only see one of the pictures, so as to achieve One display can meet the different needs of multiple viewers at the same time. Existing dual-vision displays use parallax barriers or cylindrical lenses to separate two images, or allow viewers to wear different filters to achieve the effect of displaying only one image in a certain viewing direction. However, there is an obvious shortcoming in the existing dual-view display: the display picture is a 2D picture, and 3D display cannot be realized. [0003] Integrated imagin...
