Embodiment Construction

[0026] The specific implementation manners of the three-dimensional display device provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] The film thickness and area size and shape of each layer in the drawings do not reflect the true proportion of the three-dimensional display device, but are only intended to schematically illustrate the content of the present invention.

[0028] A three-dimensional display device provided by an embodiment of the present invention, such as figure 2 As shown, it includes: a display panel 10, and a three-dimensional grating 20 disposed on the base substrate 101 on the light-emitting side of the display panel 10; wherein,

[0029] The three-dimensional grating 20 is divided into a plurality of alternate light-transmitting regions a and light-shielding regions b, and an electrochromic layer 201 is arranged at each light-shielding region b of the three-dimension...

Abstract

The invention discloses a three-dimensional display device. The three-dimensional grating is directly arranged on the base substrate on the light-emitting side of the display panel. An electrochromic layer is arranged in the light-shielding area. The electrochromic layer is in a light-shielding state when a voltage is applied, and a light-transmitting state when no voltage is applied. In the three-dimensional display mode, dark stripes can be formed in the light-shielding area, and dark stripes can be formed in the light-transmitting area. Form bright stripes to realize three-dimensional display function. In the three-dimensional display device provided by the embodiment of the present invention, the original underlying substrate of the three-dimensional grating is omitted, and the three-dimensional grating is directly arranged on the substrate substrate on the light-emitting side of the display panel, thereby reducing the overall thickness of the module, and because the saving By removing the underlying substrate of the three-dimensional grating, the loss of the transmissivity of the display device can also be reduced.

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, with the continuous development of liquid crystal display technology, three-dimensional display technology has attracted much attention. Three-dimensional display technology can make the picture three-dimensional and realistic. The information is superimposed and regenerated to form an image with a stereoscopic effect. [0003] At present, 3D display technology is mainly divided into naked-eye and glasses-based implementation methods. Among them, glasses-based 3D display technology requires wearing special glasses, which is inconvenient to carry. Therefore, more attention is paid to the development of naked-eye 3D display in tablet and mobile phone products. Currently, naked-eye 3D display methods mainly include barriers and lenticular lenses, and lenticular lenses are generally not compatible...
