Problems solved by technology

However, due to the introduction of the scattering screen 6 in this solution, the transmittance of the image will be reduced, and the image will also be distorted due to the scattering of the scattering screen; therefore, such a solution for eliminating moiré is not ideal

Embodiment Construction

[0021] Elimination of moiré in the present invention is achieved by setting the included angle between the direction of the grating marks (hereinafter referred to as the direction of the grating) and the pixel arrangement direction of the display. After repeated experiments, it is found that the angle change between the direction of the grating and the pixel arrangement direction of the display will affect the width of the generated moiré. In this way, the angle between the direction of the grating and the direction of the pixels of the display can make the width of the moiré very small so that the human eyes cannot distinguish it at a predetermined angle, and the reduction or elimination of the moiré can be achieved by using these two methods.

[0022] Overlay two rasters, as in image 3 shown. A series of intersections can be seen from the figure. These points are connected one by one, no matter horizontally, vertically or obliquely, stripes in different directions will be...

Abstract

The invention discloses a three-dimensional display device, including a display and an optical grating arranged in front of the display. The width of Mohr ripple produced between the optical grating and the display is too tiny for human to distinguish through setting up the included angle in pixel array direction between the optical grating and the display so as to eliminate and reduce the Mohr ripple produced between the optical grating and the display. The technical proposal of the invention is adopted to achieve the three-dimensional display device, thus greatly decreasing and even eliminating Mohr ripple without any additional expense and significantly improving the three-dimensional display quality.

Description

technical field [0001] The invention relates to the field of stereoscopic display, in particular to a stereoscopic display device which eliminates moiré. Background technique [0002] Displays currently on the market are mainly flat displays. With the progress and development of science and technology, three-dimensional display technology should emerge. The application of the three-dimensional display technology enables people to see three-dimensional pictures with naked eyes through the three-dimensional display without wearing stereoscopic glasses. Existing naked-eye three-dimensional displays are mainly developed based on binocular parallax, mainly grating-type 3D stereoscopic displays; Light-emitting display (OLED, etc.) is made by adding a grating. The grating can be divided into a cylindrical grating and a slit grating. The cylindrical grating is also called a cylindrical lens grating or a cylindrical lens. The slit grating is also called a visually impaired baffle o...
