Problems solved by technology

The arrangement period of the spacers is the same as or similar to the arrangement period of the pixel units on the display panel. Therefore, there is periodic interference between the spacers and the pixel units, and the image generated by the pixel units arranged in an array passes through the spacers. Moiré patterns will be formed in the image. Obviously, this moiré pattern has a great impact on the display effect of the image, which will destroy the appreciation of the image, affect the visual effect, and cause the viewer's discomfort. Moiré appears in the three-dimensional display device. Streaks will cause color distortion, or cause other colors that should not appear in parts of the image, or cause problems such as mixed light and dark lines in the display area, which will bring serious deviations to the display effect and affect the appreciation of the viewer.

Embodiment approach 1

[0037] Such as figure 2 versus image 3 As shown, the stereoscopic display device provided by the embodiment of the present invention includes a liquid crystal lens 1 and a display panel 2. The liquid crystal lens 1 is arranged on the light emitting side of the display panel 2. The display panel 2 includes a plurality of pixel units 21, and each pixel unit 21 extends along the One direction and a second direction are arranged. The first direction is perpendicular to the second direction. Therefore, the pixel units 21 arranged in the first direction and the second direction form a pixel array. The liquid crystal lens 1 includes a first substrate 11 and a The second substrate 12 is filled with liquid crystal molecules 14 between the first substrate 11 and the second substrate 12 to form a liquid crystal layer, the spacer 13 is arranged between the first substrate 11 and the second substrate 12, and the display panel 2 is provided with a display area and In the non-display area, i...

Embodiment approach 2

[0058] Such as Figure 5 As shown, the three-dimensional display device provided in this embodiment is substantially the same in structure as the three-dimensional display device provided in the first embodiment. The difference is that each spacer 13b corresponds to at least one pixel unit 21b, and the gap between two adjacent spacers 13b is The linear distance value is greater than the maximum side length of the pixel unit 21b, and the spacers 13b are arranged along the fourth direction, which is parallel to the first direction or parallel to the second direction. Compared with the prior art, this embodiment provides The arrangement of the spacers 13b becomes sparse, which reduces the arrangement density of the spacers 13b, which is beneficial to improve the moiré phenomenon. The spacers 13b can be arranged in the first direction or the second direction. When the spacers 13b are set, It should be ensured that the linear distance between two adjacent spacers 13b is greater than ...

Embodiment approach 3

[0069] Such as Figure 8 versus Picture 11 As shown, the structure of the stereoscopic display device provided in this embodiment is substantially the same as the stereoscopic display device provided in the second embodiment. The difference is that each pixel unit 210c includes 4 sub-pixels 2110c, and each sub-pixel 2110c and Arranged in the second direction to form an array arrangement, the pixel unit 210c has a fifth side length, a sixth side length, a seventh side length, and an eighth side length, wherein the fifth side length and the sixth side length are parallel and equal, and the seventh side length The length of the side is parallel and equal to the length of the eighth side, and the length of the fifth side is L 1 , The seventh side length is L 2 , And L 1 2 , The maximum side length is L 2 , The linear distance between two adjacent spacers 1130c is greater than the maximum side length of the pixel unit 210c, namely L 2 , Reducing the arrangement density of the spacer...

Abstract

The invention belongs to the technical field of stereoscopic display, and in particular relates to a stereoscopic display device, which includes a display panel and a liquid crystal lens arranged on the light-emitting side of the display panel. The display panel includes a plurality of pixel units, and each of the pixel units is arranged along a first direction and a second direction perpendicular to the first direction to form a pixel array. The liquid crystal lens includes a plurality of spacers, each of the spacers is arranged in a certain direction, and there is an arrangement difference between the arrangement period of the spacers and the arrangement period of the pixel unit, and the arrangement difference can be eliminated Periodic interference between the spacers and the pixel array eliminates moiré and improves visual effects. The invention also relates to a liquid crystal lens. The spacer arrangement period of the liquid crystal lens is different from the arrangement period of the pixel units. When the liquid crystal lens is used to display a stereoscopic image, the phenomenon of moiré is eliminated and the viewing effect is improved.

Description

Technical field [0001] The present invention belongs to the field of stereo display technology, and particularly relates to a liquid crystal lens and a stereo display device having the liquid crystal lens. Background technique [0002] Such as figure 1 As shown, the stereoscopic display device includes a liquid crystal lens 1'and a display panel 2'. The liquid crystal lens 1'is arranged on the light-emitting side of the display panel 2'. The liquid crystal lens 1'includes a first substrate 11' and a second substrate 12' which are arranged oppositely. , The first substrate 11' and the second substrate 12' are filled with liquid crystal molecules 14' to form a liquid crystal layer. The thickness of the liquid crystal layer, also called the cell thickness, has a great influence on the light adjustment effect of the liquid crystal. Therefore, in the manufacturing process of the liquid crystal lens 2', ensuring the uniformity of the cell thickness is the basis for realizing high-qual...
