Problems solved by technology

[0005] In order to solve the problem of low resolution of multi-viewpoint autostereoscopic display, domestic and foreign enterprises and R&D institutions have proposed many methods and devices for improving resolution, for example: the patent "autostereoscopic display device" ( Publication No. CN101836460) utilizes different polarized light on birefringent prisms with different refractive indices to display images from different viewpoints in time-sharing to form stereoscopic vision. , time-sharing display driver, high frame rate display device, etc.
The patent "Multi-view autostereoscopic display with improved resolution" (publication number CN101518095) applied by South Korea's Samsung Electronics Co., Ltd. uses directional backlight to display images from different viewpoints in time-sharing to form stereoscopic vision; Directional backlight, time-sharing backlight drive, high frame rate display devices, etc.
[0006] The above multi-viewpoint autostereoscopic display devices with improved resolution can keep the resolution of the display panel from dropping, but they are all realized by time-sharing display, which requires a display panel with a high frame rate and more complicated light sources. The equipment is complicated and the cost is high.

Embodiment 1

[0031] see figure 1 , the present invention discloses a multi-viewpoint autostereoscopic display device, the stereoscopic display device includes a display panel 10 and an image splitting device 20, and the display panel 10 and the image splitting device 20 are configured according to a set manner.

[0032] The image-splitting device 20 includes a plurality of image-splitting units arranged in parallel, the horizontal width of the image-splitting unit is k times the width of half a sub-pixel, k is an odd number, and each row is sequentially offset by half a sub-pixel in the same direction; The units are arranged at intervals; the color components of the viewpoint image pixels are located in the sub-pixels of the adjacent pixel rows that span the sub-image units.

[0033] Let d be the grid pitch of the image-splitting unit of the image-splitting device, and the bevel angle be θ. The configuration of the display panel and the image-splitting device is: (1) tanθ=R / T, where T is ...

Embodiment 2

[0037] In this embodiment, the stereoscopic display device includes a display panel and an image splitting device, and the display panel and the image splitting device are configured in a preset manner. see figure 2 , the sub-pixel aspect ratio is 3, T=3, R=0.5, then the slope is 1 / 6; the horizontal width of the sub-image unit is 9 and a half times the sub-pixel width, d / cos θ=9*w, then the number of viewpoints v =9. The viewpoint matrix is ​​arranged at intervals across the sub-image units, the first row is arranged circularly in the order of 0, 2, 4, 6, 8, 1, 3, 5, 7, and the second row is arranged in the order of 1, 3, 5, 7, 0, The sequence of 2, 4, 6, 8 is arranged circularly. The R, G, and B color components of the viewpoint image pixels are located in the sub-pixels of three adjacent rows across the image division unit.

[0038] see image 3 , assuming that the serial numbers of the R, G, and B color components are 0, 1, and 2 in sequence, and the serial number of the...

Abstract

The invention discloses an automatic multiple-viewpoint stereoscopic display device. The automatic multiple-viewpoint stereoscopic display device comprises a display panel and an image dividing device which are arranged in a set manner. The image dividing device comprises a plurality of image dividing units arranged in parallel, the horizontal width of each image dividing unit is k times of the width of a half sub-pixel, the k is an odd number, the image dividing units are shifted to the same direction by the half sub-pixel line by line sequentially, the viewpoints in the lines are arranged at intervals, color components of image pixels of the viewpoints are displayed by crossing the image dividing units, the display panel displays an multiple-viewpoint composite image, the image dividing device is used for spatial image dividing, so that different viewpoint images can be viewed by eyes of people, and stereoscopic visual effects are generated. The automatic multiple-viewpoint stereoscopic display device has the advantages that overall effect of the automatic multiple-viewpoint stereoscopic display device can be improved remarkably.

Description

technical field [0001] The invention belongs to the technical field of stereoscopic display, and relates to a stereoscopic display device, in particular to a multi-viewpoint automatic stereoscopic display device. Background technique [0002] Today's mainstream 3D stereoscopic display technology still cannot free us from the shackles of special glasses, which reduces its application range and comfort. Moreover, many 3D technologies will make long-time experiencers feel nausea and dizziness. Therefore, the driving force for the sustainable development of 3D stereoscopic display falls on the cutting-edge technology of naked-eye 3D display technology. [0003] One type of autostereoscopic display device is mainly composed of a display panel and an image splitting device. The display panel is usually composed of flat panel display devices such as LCD and PDP. The image splitting device is usually composed of grating devices such as slit gratings and lenticular gratings. The di...
