Problems solved by technology

In naked-eye 3D display, the more the number of viewpoints, the better the 3D image displayed, but as the number of viewpoints increases, the resolution will decrease. For example, if the number of viewpoints is Q, the displayed resolution will decrease to 1 / Q

Abstract

An embodiment of the invention provides a three-dimensional display system based on a cylindrical lens grating. The three-dimensional display system comprises a projector array, a cylindrical lens grating and a vertical diffusion film; the projector array comprises a plurality of projectors; the plurality of projectors are used for projecting images to the cylindrical lens grating; the cylindricallens grating is used for providing a light field with a three-dimensional effect; and the vertical diffusion film is used for diffusing light in the light field with the three-dimensional effect so as to form a three-dimensional image. According to the three-dimensional display system based on the cylindrical lens grating provided by the embodiment of the invention, the projector array comprisesa plurality of projectors, so that compared with the prior art, under the condition that the viewpoints are increased, higher resolution and wider viewing angle are achieved; and the problem of mutualrestriction of the number of viewpoints and the resolution ratio in the prior art is solved, and a 3D image with a better effect can be displayed.

Description

technical field [0001] Embodiments of the present invention relate to the field of optical display, and more specifically, to a three-dimensional display system based on a cylindrical lens grating. Background technique [0002] At present, naked-eye 3D display has become the mainstream development trend of the display industry. Among them, the naked-eye 3D display method based on lenticular lens grating has become the most commercialized display method for naked-eye 3D due to its advantages of simple structure and low cost. In order to improve the display effect, a lot of research work has been carried out around this naked-eye 3D method. [0003] figure 1 It is a schematic diagram of a naked-eye 3D display technology based on a lenticular grating and a liquid crystal display in the prior art, such as figure 1 As shown, the cylindrical lens grating plays the role of controlling light, and it can deflect the light emitted by the pixels on the 2D liquid crystal display to di...
