Problems solved by technology

[0005] However, if Figure 1b As shown, the light emitted by each sub-pixel of the display panel 10 will pass through the array of black matrix 12 and grating 11 respectively. Since the spatial frequencies of black matrix 12 and grating 11 are close, the light passing through black matrix 12 is the same as the light passing through grating 11. The vibration frequency is relatively close, so it is easy to interfere and form light and dark stripes, resulting in visual block, that is, as Figure 1c Moiré shown, reducing the effect of stereoscopic display

Embodiment 1

[0086] In order to eliminate the moiré generated between the grating 11 and the diagonal dark state (a-c) of the black matrix 12 . There is θ between the grating 11 and the lateral X direction of the display panel 10 to satisfy the formula:

[0087] | α - θ | > arccos P 2 [ n 2 ( A 3 × sin α ) 2 + B 2 ] - ( A 2 × sin ...

Embodiment 2

[0104] In order to eliminate the moiré generated between the grating 11 and the black matrix 12 in the lateral dark state (a-b). There is θ between the grating 11 and the lateral X direction of the display panel 10 to satisfy the formula:

[0105] θ > arccos P 2 ( n 2 A 2 + B 2 ) - A 2 B 2 2 nAB P 2 ; - - - ( 3 )

[0106] Among them, the sam...

Embodiment 3

[0110] In order to eliminate the moiré generated between the grating 11 and the longitudinal dark state (b-c) of the black matrix 12 . There is θ between the grating 11 and the lateral X direction of the display panel 10 to satisfy the formula:

[0111]

[0112] Among them, the sampling process of moiré pattern is as follows: Figure 7 As shown, there are multiple intersection points (indicated by dots) between the vertical dark state (b-c) of the black matrix 12 and the grating 11 . Select (0, 1, 2, 3...) sampling points from the above intersection points to sample the moiré pattern. There is a moiré pattern of a certain width between each sampling point and fixed point d (an intersection adjacent to the sampling point).

[0113] For example, when the sampling frequency of moiré is n=1, the moiré generated between fixed point d and sampling point 0 can be sampled, and it can be obtained that there is a moiré pattern with a width of W1 between fixed point d and sampling p...

Abstract

The embodiment of the invention provides a 3D (three-dimensional) display device and belongs to the technical field of displaying. The moire pattern phenomenon of the 3D display device is reduced compared with that of a glass-free 3D display device in the process of displaying. The 3D display device comprises a display panel and an optical grating; the display panel comprises a plurality of first display units and a plurality of second display units; each first display unit comprises m sub-pixels, and each second display unit comprises m sub-pixels, wherein the sub-pixels are arranged along the direction Y; the optical grating comprises a plurality of optical structures which are arranged in parallel; preset included angles are formed between the optical structures and the direction X of the display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a stereoscopic display device. Background technique [0002] The stereoscopic display device has the characteristics of a large amount of information and can reproduce all the three-dimensional information of the actual scene, so that the viewer can directly see the distance and depth of each object in the image from the display device, so the viewer can obtain a more comprehensive and intuitive view. Information. Therefore, with the rapid development of stereoscopic display technology, there is an increasing demand for stereoscopic display devices. Traditional stereoscopic display devices require viewers to wear auxiliary tools such as polarized glasses, complementary color glasses, or liquid crystal switching glasses. Although they have good stereoscopic effects, they are not suitable for public places, especially for advertising displays. Therefore, the naked-eye stereoscop...
