Problems solved by technology

[0007] Although adopting multi-viewpoint autostereoscopic display technology can improve the defect of viewer's dizziness caused by the parallax inversion phenomenon (or be called improving viewing comfort), one of the improvements is to sacrifice the obtained 3D image resolution and brightness for the most part. The second is that it can only alleviate the dizziness of the viewer caused by parallax inversion, but it cannot be eradicated. The third is that it greatly increases the complexity of the entire process from the system including image acquisition to terminal display. And it makes it almost impossible to be compatible with the glasses-type dual-viewpoint 3D display and even the traditional 2D display system that has been developed and popularized in the early stage

Embodiment Construction

[0020] Below, the technical solution of the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments.

[0021] As a first embodiment of the present invention, Figure 2a It is a schematic diagram of the principle of an ordinary dual-viewpoint autostereoscopic display device using a slit grating. Different from the traditional design, a vacant isolation pixel is inserted between each group of adjacent sub-image pixels of the left and right eye viewpoints arranged in a staggered manner, which is changed from the "RLRLRL..." pixel arrangement of the prior art to The pixel arrangement is "RL RL RL...", the human eyes watch the image displayed on the image display screen through each slit of the slit grating at the position shown in the figure, and the sight lines of the left and right eyes fall on the corresponding viewpoints accurately On the sub-image pixels, a normal 3D image is viewed.

Abstract

The invention discloses a grating-type autostereoscopic display device, which includes an image display screen and a grating module arranged in front of the image display screen, wherein: the image display screen arranges the image display pixels in an order of right and left viewpoints in a periodic staggered order, and A vacant isolation pixel is inserted between each group of viewpoint pixel arrangement periods. The invention can not only fundamentally eliminate the dizziness phenomenon, but also be compatible with the existing glasses-type dual-viewpoint 3D program sources.

Description

technical field [0001] The invention relates to the technology of displaying autostereoscopic images on a display screen, in particular to a grating type autostereoscopic display device. Background technique [0002] For 3D display technology, the naked-eye stereoscopic display technology without wearing special glasses is the ultimate development direction, and the grating autostereoscopic display technology is a relatively mature and feasible technical means to achieve naked-eye stereoscopic display, and the grating autostereoscopic display is the most The simple one is the dual-viewpoint autostereoscopic display technology, and the dual-viewpoint autostereoscopic display technology can directly use a large number of dual-viewpoint 3D program sources based on the glasses-type stereoscopic display method, and has strong compatibility. [0003] However, there is a 50% probability of abnormal viewing areas in the dual-viewpoint autostereoscopic display technology. These abnor...
