AI Technical Summary

Problems solved by technology

The image resolution of the multi-viewpoint stereoscopic display is low, especially the vertical definition is reduced to 1 / 3 of the 2D image, so it is not suitable for displaying fine images and characters. In order to display high-precision 2D images and characters without loss, related technologies The staff has developed a 2D / 3D convertible grating. When playing a stereoscopic program, the grating is in a 3D state, and when playing a flat program, the grating is in a 2D state.

Embodiment Construction

[0026] A 6-viewpoint high-definition stereoscopic display is built with a 47-inch 120Hz full high-definition LCD.

[0027] Prepare a 47-inch LCD screen with a refresh rate of 120Hz and a pixel pitch of 0.5415mm. The twill grating (1) is made of cylindrical lens grating film bonded with optical glass, installed in parallel outside the LCD (3), the grating pitch of the twill grating is 0.8992mm, the inclination angle to the horizontal direction is 56.31°, and the cylinder faces inward Maintain a proper distance from the LCD (3), so that the stereoscopic image is on the focal plane of the lenticular grating. An odd-even field switching layer (2) composed of a liquid crystal switch is arranged between the diagonal grating and the LCD, the pitch of the transverse slit is 0.5415mm, and the width of the light-transmitting slit is 0.2707mm. Each image source of the 6-lens parallax sequence is cropped according to the aspect ratio of 16:9, and then non-proportionally scaled to 960*720...

Abstract

The invention discloses a high-definition automatic stereoscopic display, which comprises a stereoscopic image player, an LCD (liquid crystal display) with high refresh rate and a grating with oblique grains. An odd and even field switching layer is assorted between the grating with the oblique grains and the LCD, odd-row pixels of a stereoscopic image are combined to form an odd-field image, even-row pixels of the stereoscopic image are combined to form an even-field image, the odd-field image and the even-field image are alternately displayed on the LCD screen capable of realizing frequency doubling scanning in a point-to-point manner, longitudinal definition of the stereoscopic image can be doubled, and besides the function of displaying the stereoscopic image, high-definition planar images or characters can be directly displayed without 2D (two-dimensional) / 3D (three-dimensional) conversion.

Description

Technical field: [0001] The invention relates to an autostereoscopic display, more specifically, to a high-definition autostereoscopic display, which can be used in stereoscopic televisions, 3D game machines, 3D video advertisements, and the like. Background technique: [0002] The three-dimensional display has the characteristics of large amount of information and can reproduce all the three-dimensional information of the actual scene, so that the viewer can directly see the distance and depth of each object in the image from the display, so the viewer can obtain more comprehensive and intuitive information . Traditional stereoscopic displays require viewers to wear auxiliary tools such as polarized glasses, complementary color glasses, or liquid crystal switch glasses. Although they have a good stereoscopic effect, they are not suitable for many occasions. [0003] In recent years, the autostereoscopic technology without glasses has been actively researched, and its repre...
