Liquid crystal lens and stereoscopic display device

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...

AI Technical Summary

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.
