Problems solved by technology

However, because the traditional multi-view stereoscopic display 10 uses the vertical fence barrier 30 to produce a three-dimensional effect, the lateral resolution of the traditional multi-view stereoscopic display 10 is greatly reduced.
In addition, due to the interaction between the display panel 20 and the vertical barrier barrier 30, severe interference fringes will be generated, which will lead to adverse interference in stereoscopic image viewing.

Abstract

The invention provides a multiple visual field stereo display, containing plural equivalent pixels and at least one oblique fence protective screen; wherein the equivalent pixels also contains plural first, second, third and fourth visual angle secondary pixels. The first, second, third and fourth visual angle secondary pixels of the equivalent pixels form a line from left to right in recursive sequence of first, second, third and fourth visual angle secondary pixels; the oblique fence protective screen is provided with plural transparent areas and plural shielding areas, the transparent areas and the shielding areas are in long strip and oblique parallel arrangement, and the arrangement direction of the transparent area is not parallel or vertical to the line. The length-width ratio of the equivalent pixels of the stereo display of the invention is more close to 1, and the transparent area of the oblique fence is provided with an oblique angle, thus improving the lateral resolution of the multiple visual field stereo display, causing the present image picture to be more delicate and reducing interference ripple generated by the display panel and the fence protective screen.

Description

【Technical field】 [0001] The invention relates to a multi-view stereoscopic display, in particular to a multi-view stereoscopic display with oblique fence barriers. 【Background technique】 [0002] As shown in FIG. 1 , when a person's eyes are looking at an object, the left eye L and the right eye R receive images 7 and 8 at different angles and positions respectively, and then synthesize and recognize them into a three-dimensional image through the brain 5 . If a display can respectively display the images seen by the left eye L and the right eye R when the viewer looks at an object 6, and accurately transmit the images to the left eye L and the right eye R respectively, then it can be perceived through synthesis by the brain 5 to stereoscopic images. Therefore, if the image information of different angles of an object can be displayed on the display as the images seen by the corresponding left and right eyes respectively, and are accurately transmitted to the left and righ...
