Example Embodiment

[0016] The invention includes a display panel (LCD or LED), a slit grating and multiple baffle structures. Wherein, the slit grating is a vertical flat plate installed in front of the display panel, and each grating unit is divided into a transparent part and an opaque part. For each eye, it blocks a part of the screen, so that the light of the pixel belonging to the left viewpoint all enters the field of view of the left eye, and the light of the pixel belonging to the right viewpoint all enters the field of view of the right eye. However, due to the shading effect of the opaque part of the slit grating, the displayed image is darker. According to the type of display panel, the multiple baffle structures, if applied to LCD type displays, can be placed in the liquid crystal layer in the display panel, specifically located on the black matrix between two pixels. It is smaller than the thickness of the liquid crystal layer; if it is applied to an LED display, it can be placed in...

Abstract

The invention belongs to the technical field of visual patterns, and provides three-dimensional display equipment which can be used for expanding the naked eye free three-dimensional display visual area range, lowering the crosstalk degree of different viewpoints within the range and improving the 3D display effect. According to the technical scheme, the visual area expanding low-crosstalk free three-dimensional display device comprises a slit grating mounted on the front portion of a display panel and a sloping baffle, each optical grating unit of the slit grating is divided into a transparent part and a nontransparent part, the nontransparent parts block one part of the display panel, the sloping baffle has a certain height, an included angle is kept between the sloping baffle and the display panel, light of pixels which belong to a left viewpoint is made to shoot into a left eye vision field, and light of pixels which belong to a right viewpoint is made to shoot into a right eye vision field. The visual area expanding low-crosstalk free three-dimensional display device is mainly applied to design and manufacture of visual pattern display devices.

Description

technical field [0001] The invention belongs to the field of visual image technology, and relates to naked-eye 3D autostereoscopic display technology, in particular, to a low-crosstalk autostereoscopic display device with extended viewing area. Background technique [0002] The most effective channel for human beings to obtain information is through vision. Since the human eyes see the real three-dimensional scene in nature, it has always been the goal pursued by human beings to be able to reproduce the real three-dimensional scene on the screen. With the improvement of two-dimensional image compression, transmission, and display technology, the next goal for human beings to pursue the reproduction of real natural scenery is to reproduce the three-dimensional information of the scenery. Stereoscopic information reproduction technology will definitely become the next hot spot in the development of information technology after voice, data, and plane image services. Stereosco...
