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 and image 3As 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 is arranged along the first One direction and the second direction are arranged, wherein the first direction is perpendicular to the second direction, so each pixel unit 21 arranged along the first direction and the second direction forms a pixel array, and the liquid crystal lens 1 includes the first substrate 11 and the first substrate 11 arranged oppositely. The second substrate 12, the first substrate 11 and the second substrate 12 are filled with liquid crystal molecules 14 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 pro...

Embodiment approach 2

[0058] Such as Figure 5 As shown, the structure of the stereoscopic display device provided in this embodiment is substantially the same as that of the stereoscopic display device provided in Embodiment 1, the difference is that each spacer 13b corresponds to at least one pixel unit 21b, and the space between two adjacent spacers 13b The linear distance value is greater than the maximum side length of the pixel unit 21b, each spacer 13b is arranged along the fourth direction, and the fourth direction 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 along the first direction or the second direction. When setting the spacers 13b, It should be ensured that the linear distance value between two adjacent spacers 1...

Embodiment approach 3

[0069] Such as Figure 8 and Figure 11 As shown, the structure of the stereoscopic display device provided in this embodiment is substantially the same as that of the stereoscopic display device provided in Embodiment 2, except that each pixel unit 210c includes four sub-pixels 2110c, and each sub-pixel 2110c is along the first direction 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 side length is parallel and equal to the eighth side length, and the side length value of the fifth side length is L 1 , the side length of the seventh side 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, ie L 2 , reducing the...

Abstract

The invention belongs to the technical field of stereo display and particularly relates to a stereo display device which comprises a display panel and a liquid crystal lens arranged on the light-emitting side of the display panel. The display panel comprises a plurality of pixel units which are arranged in the first direction and the second direction perpendicular to the first direction to form a pixel array. The liquid crystal lens comprises a plurality of photo spacers which are arranged in a certain direction, and an arrangement difference exists between the arrangement cycle of the photo spacers and the arrangement cycle of the pixel units. The arrangement difference can eliminate the cyclic interference between the photo spacers and the pixel array, eliminate moire and improve visual effects. The invention further relates to the liquid crystal lens, the arrangement cycle of the photo spacers of the liquid crystal lens is different from the arrangement cycle of the pixel units, and when the liquid crystal lens is used for displaying stereo images, the moire phenomenon is avoided, and the watching effect is improved.

Description

technical field [0001] The invention belongs to the technical field of stereoscopic display, and in particular relates to a liquid crystal lens and a stereoscopic display device with 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', and the liquid crystal lens 1' includes a first substrate 11' and a second substrate 12' oppositely arranged. 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 known as the cell thickness, has a great influence on the light-regulating effect of the liquid crystal. Therefore, in the manufacturing process of the liquid crystal lens 2', ensuring the uniformity of cell thickness is the basis for realizing high-qua...
