Problems solved by technology

In this structure, due to the mismatch between the slanted line of sight formed by the slanted grating and the shape of the rectangular pixel, it will cause crosstalk between the parallax sub-images seen by the human eye, which will bring more ghosts (Ghost) phenomenon, and the image display quality will be improved.

Embodiment Construction

[0020] It should be noted that, if there is no conflict, the embodiments of the present invention and various features in the embodiments can be combined with each other, and all are within the protection scope of the present invention.

[0021] Such as figure 1 As shown, in the existing naked-eye stereoscopic display, the lens grating 02 is generally located in front of the display panel 01 (that is, the side close to the viewer), and the display panel 01 is placed on the focal plane of the lens grating 02, and the display panel 01 The emitted light is split by the lens grating 02 to form parallel light in various viewing directions and enters the human eye. The human eye can easily find the moiré fringes appearing on the display screen, which affect the viewing effect.

[0022] The present invention expands the placement position of the display panel beyond the equivalent focal plane of the lens grating through the lens grating with aberration, so that the light emitted by t...

Abstract

The invention provides a stereo display device and relates to the technology field of photoelectricity. The stereo display device is capable of weakening moire pattern and improving stereo display effect. The stereo display device comprises a display panel and a transmission grating, wherein the display panel and the transmission grating are arranged in parallel. The transmission grating comprises a plurality of lens units. Each lens unit is provided with aberration. The distance H between the display panel and the transmission grating is equal to F plus or minus delta, wherein the F is the equivalent focal length of each lens unit and the delta is adjustment threshold. The stereo display device is suitable for the display device manufacturing field.

Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to a stereoscopic display device. Background technique [0002] Naked-eye stereoscopic display technology provides different perspective images for both eyes through refraction in the horizontal direction through parallax barrier gratings or lens gratings. An image with complete depth information can be obtained under the condition of naked eyes to realize a stereoscopic display effect. [0003] However, the display panels used in the naked-eye stereoscopic display technology, whether it is a liquid crystal display panel or a plasma display panel, have pixel units arranged at equal intervals in the horizontal and vertical directions, and each pixel unit forms equal intervals in the horizontal and vertical directions. Opaque stripes, that is, black matrix. The grating structure used, whether it is a parallax barrier grating or a lens grating, is an optical device arranged i...
