Three-dimensional multi-view display device and manufacturing method

Abstract

According to the three-dimensional multi-view display device and the manufacturing method, the three-dimensional multi-view display device sequentially comprises a display screen, a three-dimensional multi-view display grating and a multi-view three-dimensional window in the light direction, and the three-dimensional multi-view display grating is composed of a first layer of steering grating and a second layer of pixel grating. The steering grating is an inclined grating, a blazed grating or a continuous gray grating; the pixel grating corresponds to each pixel on the display screen and diffracts red, green and blue light emitted by each pixel of the display screen to a multi-view area of the multi-view three-dimensional window, so that three-dimensional multi-view display is realized. The three-dimensional multi-view display double-layer grating can be produced and copied on a large scale, can be widely used in the field of three-dimensional display screens, and is a core key technology with an important prospect in the field of three-dimensional display screens.

Description

technical field [0001] The present invention relates to a three-dimensional display grating, especially a three-dimensional multi-viewpoint display device and a manufacturing method, especially a combination of a steering grating and a pixel grating, which can be used as a means of three-dimensional display and applied to various screens for three-dimensional display. Stereoscopic display, including mobile phone screens, computer screens, and other display screens, realizes the effect of multi-viewpoint stereoscopic display. Background technique [0002] Three-dimensional display has always been the goal pursued by modern science and technology, especially the use of mobile phones, computers, televisions, and large display screens to produce three-dimensional display effects is an important and promising direction. [0003] The current mobile phone screens, computer screens, etc. are all two-dimensional displays. In the future, three-dimensional display screens may be develo...

Problems solved by technology

[0008] The problem is that each point on the screen of the mobile phone is projected to a different viewpoint, so it is necessary to use different density gratings. It is difficult to achieve high efficiency, polarization-independent, and broadband, which can meet the requirements of red, green and blue three-color light of screen pixels. It is very difficult to make blazed gratings or gratings with continuous grayscale changes, and the processing process is very difficult. Precise control ensures that the processed continuous grating has good performance
