3D display device and method

Abstract

The invention provides a 3D display device and method. The 3D display device comprises a display panel and a grating panel, wherein the display panel is used to display left-eye and right-eye images, and the grating panel is arranged in the light output side of the display panel to form a grating. The 3D display device further comprises a human eye position tracking unit and a display panel adjusting unit and / or a grating panel adjusting unit, the eye position tracking unit is used to track position information of the human eyes, the display panel adjusting unit adjusts the relative position of the left-eye and right-eye images displayed by the display panel according to the position information of the human eyes, and the grating panel adjusting unit adjusts the position and / or width of an opening area of the grating panel according to the position information of the human eyes and the arrangement manner of the left-eye and right-eye images displayed by the display panel. The 3D display device can ensure that an observer can watch 3D images when the position of the observer changes.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a 3D display device and a 3D display method. Background technique [0002] 3D display technology can enable viewers to see stereoscopic images, which can improve the realism of the display. The specific implementation principle of 3D display technology is to display two images at the same time or successively, which are respectively received by the left and right eyes of the viewer, and the images received by the left and right eyes of the viewer are processed in the brain into a A three-dimensional layered image screen, so that the viewer can have a three-dimensional effect, which is the so-called 3D display. [0003] Existing 3D display devices can be divided into two types. The first type requires additional 3D glasses to realize 3D display, while the other type does not need 3D glasses and can realize naked-eye 3D display. [0004] figure 1 It is a schematic ...

AI Technical Summary

Problems solved by technology

[0005] the above figure 1 The naked-eye 3D display device shown can realize 3D display, but it has the following problems in practical applications: the grating formed by the grating panel 2 is a fixed grating, and when the viewer is at a specific position, the left and right eyes of the viewer can respectively see the display panel 1 Left-eye and right-eye images are displayed, but if the viewer's position changes, such as when the viewer is walking around, there will be "crosstalk" in the images the viewer sees

Taking the left eye as an example, the so-called "crosstalk" means that through the opening area of ​​the grating formed by the grating panel 2, the left eye cannot see the left eye image displayed on the display panel 1, but sees the right image displayed on the display panel 1. eye image, or see the left eye image and the right eye image displayed on the display panel 1 at the same time; thus in this case, the viewer cannot watch the 3D image
