Problems solved by technology

[0004] However, the optimal viewing distance of the current naked-eye 3D display is fixed after the production is completed. If the user wants to watch the 3D effect without crosstalk, the viewing distance cannot be changed arbitrarily.

Embodiment Construction

[0028] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] figure 2 It is a schematic diagram of a naked-eye 3D display device provided by an embodiment of the present invention. The naked-eye 3D display device includes a grating 30 and a display panel 10 arranged oppositely, and a distance adjustment structure 20 is arranged between the grating 30 and the display panel 10 , the distance adjusting structure 20 is used to adjust the distance between the grating 30 and the display panel 10 .

[0030] The naked-eye 3D display device provided by the embodiment of the present invention can adjust the distance between the grating and the display panel by setting a distance adjustment structure between the grating and the displa...

Abstract

The invention provides a naked-eye 3D display device. The naked-eye 3D display device comprises an optical grating and a display panel opposite to the optical grating. A distance adjusting structure is arranged between the optical grating and the display panel. The distance adjusting structure is used for adjusting the distance between the optical grating and the display panel. According to the naked-eye 3D display device, the distance adjusting structure is arranged between the optical grating and the display panel, so that the distance between the optical grating and the display panel is adjusted, the best viewing distance of the naked-eye 3D display device is changed, and a user can watch 3D videos at different viewing distances with no crosstalk.

Description

technical field [0001] The invention relates to the display field, in particular to a naked-eye 3D display device. Background technique [0002] The display devices used in daily life generally adopt two-dimensional display, which cannot intuitively represent the depth information of the scene. With the development of computer information technology and display technology, three-dimensional display technology has become a research focus in the field of display. The working principle of three-dimensional (3D) display technology is: for the same scene, the left eye and right eye of the viewer receive images respectively, and the position difference generated by the interpupillary distance between the two eyes of the viewer is reflected in the left eye and the right eye of the viewer. Two slightly different images will appear on the retina of the right eye. This difference is called "binocular parallax", and the two different images form a "stereoscopic image pair". After the...
