Problems solved by technology

[0005] With the gradual thinning of electronic products, existing stereoscopic display devices have the problem that when the size of the display panel is larger, the thickness of the stereoscopic display device becomes thicker.

Embodiment Construction

[0055] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0056] Please refer to figure 1 and figure 2 , which are respectively a three-dimensional schematic diagram of an embodiment of the stereoscopic display device disclosed in the present invention and the basis figure 1 Side view of a stereoscopic display device. The stereoscopic display device 100 includes a pixel array 102 and a lens array 104 . The pixel array 102 includes a plurality of sub-pixel units 31, a plurality of sub-pixel units 32, and a plurality of sub-pixel units 33, wherein the plurality of sub-pixel units 31, the plurality of sub-pixel units 32, and the plurality of sub-pixel units 33 can sequentially intersect along the first direction F permutations (such as figure 1 shown), and one sub-pixel unit 31 , one sub-pixel unit 32 and one sub-pixel unit 33 can form one pixel 50 . In this embodiment, the pixel ...

Abstract

Disclosed is a three-dimensional display device which includes a pixel array and a lens array. The pixel array includes a plurality of sub-pixel units. The lens array includes a plurality of lenses. Each lens includes a center face, an incident face, a first light emergent face and a second light emergent face, wherein the first light emergent face and the second light emergent face are in face symmetry relative to the center face and are different in centers of curvature. In the same lens, the incident face receives light sent by the N sub-pixel units, and the first light emergent face and the second light emergent face emit light received by the incident face so that a plurality of viewpoints are formed at a viewpoint end, wherein N is larger than or equal to 4 and is an integer. Because light emitted by the first light emergent face and the second light emergent face is arrayed in a staggered manner, the curvature of the lens array is larger than that of a common lens array with non-staggered array and thus the focal distance is comparatively small. Therefore, the three-dimensional display device has a thinning design.

Description

technical field [0001] The invention relates to a display device, in particular to a stereoscopic display device. Background technique [0002] At present, there are mainly two methods for stereoscopic display devices to display stereoscopic images. One is that the viewer must wear special glasses to watch the display device, so that the images received by the left eye and the right eye are different, or the images received by the left eye and the right eye are different. Three-dimensional images are produced by alternating eye images. This method requires the viewer to wear additional glasses to see the three-dimensional images, which is inconvenient to use. [0003] The other is a naked-eye display device. This method is to use the grating principle for the display device, so that the viewer does not need to wear any additional devices to make the images seen by the left eye and the right eye different and generate a three-dimensional image. It is currently used in printe...
