Abstract

Embodiments of the disclosure disclose a control method and a control apparatus for a naked eye 3D display apparatus and a naked eye 3D display apparatus. The control method for a naked eye 3D display apparatus comprises the following steps of: detecting the position of a user; determining viewpoints where the left eye and right eye of the user are located according to the detected position of the user; and turning on sub-pixels corresponding to the determined viewpoints and turning off other sub-pixels. Thus, by such a control method for a naked eye 3D display apparatus of the disclosure, a user is caused to only see those display pictures corresponding to viewpoints that need to be seen, thereby solving the problem of cross-talk between multiple viewpoints existing in the prior art.

First claim

1 . A control method for a naked eye 3D display apparatus, comprising:
detecting the position of a user; determining viewpoints where the left eye and right eye of the user are located according to the detected position of the user; and turning on sub-pixels corresponding to the viewpoints and turning off other sub-pixels.

2 . The control method of claim 1 , wherein the step of detecting the position of a user comprises:
detecting the position coordinate of the user by a human face recognition technique.

3 . The control method of claim 1 , wherein, before the step of detecting the position of a user, the control method further comprises a step of creating a database, wherein the database comprises a corresponding relationship between the positions of the user and viewpoints where the left eye and the right eye of the user are located.

4 . The control method of claim 3 , wherein the step of creating a database comprises:
detecting multiple position coordinates, and determining a viewpoint corresponding to each position coordinate according to a display picture seen at each position coordinate; and creating a database according to the position coordinates and the viewpoints corresponding to the position coordinates.

5 . The control method as claimed in claim 3 , wherein the step of determining viewpoints where the left eye and right eye of the user are located according to the detected position of the user comprises: determining viewpoints where the left eye and right eye of the user are located by querying the database according to the detected position of the user.

6 . A control apparatus for a naked eye 3D display apparatus, comprising:
a position detection unit for detecting the position of a user; a viewpoint determination unit for determining viewpoints where the left eye and right eye of the user are located according to the position of the user detected by the position detection unit; and a pixel control unit for turning on sub-pixels corresponding to the viewpoints and turning off other sub-pixels.

7 . The control apparatus of claim 6 , wherein the position detection unit comprises a human face recognition module, and the position detection unit is used for detect the position coordinate of the user by the human face recognition module.

8 . The control apparatus of claim 6 , further comprising:
a database creation unit for creating a database, the database comprising a corresponding relationship between the positions of the user and viewpoints where the left eye and the right eye of the user are located.

9 . A naked eye 3D display apparatus, characterized in that, the naked eye 3D display apparatus comprises the control apparatus for a naked eye 3D display apparatus as claimed in claim 6 .

10 . The naked eye 3D display apparatus as claimed in claim 9 , characterized in that, the naked eye 3D display apparatus comprises a display panel and a grating, wherein the display panel comprises red sub-pixels, green sub-pixels and blue sub-pixels, and the grating comprises light transmission stripes, and wherein the extension direction of the light transmission stripes is parallel to the arrangement direction of sub-pixels corresponding to a single viewpoint, and along the extension direction of the light transmission stripes, the sub-pixels corresponding to a single viewpoint comprise red sub-pixels, green sub-pixels and blue sub-pixels.
