Embodiment Construction

[0029] The specific implementation manners of the curved grating structure, the display panel and the display device provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Wherein, the shape and size of each structure in the drawings do not reflect the real proportion of the curved grating structure, and the purpose is only to schematically illustrate the content of the present invention.

[0031] An embodiment of the present invention provides a curved grating structure, such as Figure 4 As shown, it includes: a plurality of grating strips arranged at intervals; the figure formed between the center points of every two adjacent grating strips is regarded as a grating period;

[0032] The width of each grating period decreases successively from the center to the edge of the curved grating structure.

[0033] Specifically, such as Figure 4 As shown, the width of each grating period is from ...

Abstract

The invention discloses a curved surface grating structure, a display panel and a display device, comprising: a plurality of grating strips arranged at intervals; a pattern formed between the center points of every two adjacent grating strips is regarded as a grating period; each grating The width of the period decreases successively from the center to the edge of the curved grating structure. Since the above-mentioned curved grating structure provided by the embodiment of the present invention arranges the grating period in this way, the best observation area can be expanded, especially in the depth direction, there is a wider observation space, so when the observer moves back and forth, also Can have a better viewing experience.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a curved grating structure, a display panel and a display device. Background technique [0002] At present, naked-eye 3D displays usually use the method of lens grating method. The basic method is to divide the display screen into two images with different angles suitable for left and right eyes, and present multiple interactive images to the viewer through the function of lens grating. The spaced left and right viewing areas allow the viewer to see different images with their left and right eyes, thereby forming a 3D effect. [0003] In order to reduce the crosstalk between the pictures of different viewpoints, the naked-eye 3D display technology can generally adopt a curved grating structure, such as figure 1 As shown, the commonly used curved grating structure includes a plurality of grating bars arranged at intervals and evenly distributed, and the distance A between the ce...
