Abstract

The invention discloses a three-dimensional display device, which comprises a plurality of sub-pixels and a plurality of grating structures corresponding to each sub-pixel; each grating structure is used to emit light in a specified direction, so that the emitted light of the three-dimensional display device The eyes are converged into at least two viewpoints, and the right eye is converged into at least two viewpoints. In this way, the three-dimensional display device can realize monocular focus three-dimensional display, so that the viewing distance of the three-dimensional display device can be designed as the viewing distance of the parallax three-dimensional display. When the distances are equal, it is ensured that the focusing position of the monocular is consistent with the converging position of the line of sight of the two eyes, thereby preventing the viewer from feeling dizzy when watching the three-dimensional display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a three-dimensional display device. Background technique [0002] At present, three-dimensional (Three-Dimensional, 3D) display technology has attracted much attention. It can make the picture three-dimensional and realistic. Superimposed and regenerated to form images with stereoscopic effects. [0003] When the human eye observes objects in the real environment, such as Figure 1a As shown, the focus position of one eye is the same as the convergent position of the line of sight of both eyes. When human eyes observe the picture displayed by the 3D display device, such as Figure 1b As shown, the focus position of the single eye is located on the screen M of the 3D display device, and the line of sight of the two eyes will converge to the virtual picture at a certain distance from the screen of the 3D display device due to parallax. , causing the viewer to feel dizzy...
