Description

 Eye 3D display method and eye 3D display device

 Embodiments of the present invention relate to a tree eye 3D display method and a tree eye 3D display device. Background technique

 At present, the common eye 3D display device is roughly divided into a parallax barrier type and a lens grating type. The most basic method is that the odd and even pixels of the display screen respectively display two parallax images of the left and right eyes (this is called two viewpoints). The eye 3D display technology), through the action of the parallax barrier or the lens grating, presents a plurality of mutually alternate left and right viewing zones, wherein the left viewing zone corresponds to the left parallax image and the right viewing zone corresponds to the right parallax image . When the left eye of the user is located in the left viewport and the right eye is located in the right viewport corresponding to the left viewport, the left eye of the user can see the corresponding left eye image, and the right eye can see the corresponding right eye image, the left eye image and The right eye image is a pair of stereo image pairs so that the brain can fuse them into a 3D image.

 For the two-view display, the user is more likely to be in the "dead zone" of the 3D display, that is, the user's left eye is in the right viewport and the right eye is in the left viewport, and the left eye sees the right eye image while the right eye sees the left eye. image. Therefore, the user not only does not see the 3D stereoscopic image, but also causes visual fatigue. The two-point eye 3D display method has a 50% chance of appearing in the dead zone.

 In order to solve this problem, on the basis of two viewpoints, a multi-view eye 3D display with more than two viewpoints appears. Due to the increase in the number of viewpoints, the number of 3D "dead zones" of the eye is greatly reduced under the same conditions, and the more the number of viewpoints, the fewer the number of 3D "dead zones" of the eye. .

 However, the more the number of viewpoints of the display, the higher the manufacturing cost of the display, the smaller the 3D resolution, and the 3D display dead zone cannot be completely eliminated. Summary of the invention

 Step S101: Input a monochrome picture signal to a sub-pixel group for displaying an edge view, where the edge view is one of two side edge views of each view group of the plurality of view groups;

 Step S102, inputting a viewpoint image signal to each sub-pixel group other than the sub-pixel group to which the monochrome picture signal is input.

 In the prior art, there are a plurality of ways in which each sub-pixel is combined to form a plurality of sub-pixel groups. According to a certain combination of sub-pixels in the prior art, sub-pixels at different positions are combined into a plurality of sub-pixel groups, the number of sub-pixel groups is the same as the number of viewpoints, and each sub-pixel group is correspondingly displayed. An image of a viewpoint. After passing through the parallax barrier or the lens grating, the light emitted by each sub-pixel group forms a plurality of clearly imaged viewing areas at a distance from the display screen.

 Illustratively, the number of viewpoints is four at this time. As shown in FIG. 1 , a plurality of viewing zones respectively corresponding to the first viewpoint may be clearly presented in front of the user, and multiple viewing zones corresponding to the second viewing point correspond to the third A plurality of viewing zones of the viewpoint and a plurality of viewing zones corresponding to the fourth viewpoint.

The third viewing zone collectively refers to the plurality of viewing zones corresponding to the fourth viewing point as the fourth viewing zone. The images displayed in the above viewing zones are images obtained by shooting different angles of a certain scene, and each angle has a certain angular difference. Two adjacent viewing zones in the four viewing zones can be combined to allow the user to see the desired 3D display.

For convenience of description, the first viewing zone, the second viewing zone, the third viewing zone, and the fourth viewing zone, which are sequentially adjacent in FIG. 1, are named as one viewing zone group 2. When the user’s right eye is located in the first viewport, the second viewport, In either of the third viewing zones, the left eye must be positioned adjacent to another viewing zone within the same viewing zone group that can cooperate with one of the three viewing zones to form a 3D effect. As shown in FIG. 1, when the right eye of the user is located in the second viewing zone, the left eye must be positioned in the third viewing zone adjacent to the second viewing zone, and the user can view the ideal 3D display effect.
