Stereoscopic display device and stereoscopic display method

【Technical field】

The present invention relates to a display device and a display method, in particular to a stereoscopic display device and a stereoscopic display method.

【Background technique】

Display technology has developed rapidly in recent years, and stereoscopic display is an important development direction. Among the existing stereoscopic display technologies, one type requires the audience to wear specific equipment (such as polarized glasses) to watch. This type of technology has been widely used commercially. For example, the well-known stereoscopic movie uses this technology. The technology is relatively mature, but it will bring an extra burden to the audience. Another type of technology to achieve stereoscopic display is Autostereoscopic Display Apparatus. This type of display device is usually composed of a display substrate and micro-optical components (such as parallax barriers or lens arrays). The image corresponding to a certain field of view is displayed on the corresponding pixel, or the image corresponding to a certain field of view is displayed at different times, and the function of the micro-optical component is to project the image corresponding to a certain field of view to the corresponding viewshed in space. When the viewer's left and right eyes are respectively located in the appropriate field of vision, they will see different images, and then synthesize and perceive stereoscopic vision in the brain. Chinese patent application CN87106723 introduces an autostereoscopic display device, the principle of which will be briefly introduced below with reference to FIG. 1 .

FIG. 1 is a schematic partial top view of a stereoscopic display device 90 in the prior art, which includes a display substrate 91 and a lens array 92. The display substrate includes pixels 91a of group A and pixels 91b of group B staggered. The A group of pixels 91a and the B group of pixels 91b respectively display images of the same thing taken from two viewing angles. The lens array 92 refracts the light emitted from the group A pixels 91 a to the first viewing area 8A, and refracts the light emitted from the B group pixels 91 b to the second viewing area 8B. When the two eyes of a person are respectively located in the first viewing area 8A and the second viewing area 8B, the two eyes will see images taken from two viewing angles, thereby presenting a stereoscopic image in the mind. Please refer to FIG. 2. FIG. 2 is another stereoscopic display device 90' in the prior art. In order to allow multiple people to watch the displayed content at the same time, the A group of pixels 91a' and the B group of pixels 91b' in the figure respectively display two Images of the same thing taken from different perspectives. The lens array 92' refracts the light emitted from the group A pixels 91a' to the first viewing area group having a plurality of first viewing areas 8A'; A second viewing group for domain 8B'.

However, in actual products, due to design and technical limitations, micro-optical components cannot project 100% of the image corresponding to a certain field of view to the corresponding field of view group in space, plus all possible problems in the manufacturing process Therefore, in actual viewing, the human eye in a certain field of view will also see images that should correspond to other groups of fields of view. Please refer to FIG. 3 . FIG. 3 is a schematic diagram of a comparison between an image originally received by the display device shown in FIG. 1 and an image projected to each viewing area. The image 70 has a white circle 701 on the gray background 702; the image 75 has a white square 751 on the gray background 752; after the display device 90 receives the information of the image 70 and the image 75, the A group of pixels display the image 70 Projected to the first viewing area 8A, the image 75 displayed by group B pixels is projected to the second viewing area 8B; ideally, the images observed by human eyes in the viewing areas 8A and 8B should be consistent with the images 70 and 75 respectively, but due to Part of the light in the image of the group B pixels dissipates to the viewing area 8A, and part of the light in the image of the A group of pixels dissipates to the viewing area 8B. The image observed by the human eye in the viewing area 8A except the gray background 712 and the white circle 711 In addition, an additional light gray square 713 will be seen; in addition to the gray background 752 and the white square 761 on the image observed by the human eye in the field of view 8B, an additional light gray circle 763 will also be seen. This phenomenon is often called ghost image or crosstalk. The final impact of ghosting or crosstalk is to reduce the quality of the stereoscopic image, causing discomfort to the user, and even headaches and dizziness.
