A 3D light field display system

Abstract

The embodiment of the invention provides a 3D light field display system. The 3D light field display system includes a 2D image generation apparatus and a composite grating, wherein the 2D image generation apparatus is used for projecting a 2D image to the composite grating; the composite grating is a grating structure at the slit of a slit grating, and the grating structure is provided with a cylindrical lens; and the composite grating is used for providing a light field with a stereo effect for the 2D image projected by the 2D image generation apparatus to form a 3D image. By setting the composite grating with the cylindrical lens at the slit of the slit grating, the 3D light field display system can solve the problem that the resolution is reduced when a current 3D light field display system increases the visual angle, thus guaranteeing that increase of the pitch does not cause reduction of resolution while increasing the viewing angle, and at the same time can improve the display luminance of the 3D image, compared with a traditional slit grating.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of light field display, and in particular, to a 3D light field display system. Background technique [0002] With the rapid development of science and technology, naked-eye 3D display has become the mainstream development trend of the display industry. Among them, naked-eye 3D display devices based on slit gratings or cylindrical lens gratings can construct viewpoints of three-dimensional objects at different positions in space. Due to the advantages of low cost and simple structure, naked-eye 3D display devices based on slit gratings or cylindrical lens gratings have a high degree of commercialization. [0003] Such as figure 1 The naked-eye 3D display system based on the slit grating 102 is shown, wherein the slit grating 102 plays a role of controlling light, and can guide the light emitted by the pixels on the 2D display screen 101 to different positions in space. figure 1 The vie...
