Control method and a control apparatus for a naked eye 3D display apparatus and a naked eye 3D display apparatus

A control apparatus for a naked eye 3D display apparatus, comprising:

• a database creation unit for obtaining multiple position coordinates within the visual area of the naked eye 3D display apparatus, such that a maximum distance between any two neighboring position coordinates of the multiple position coordinates within the visual area is not more than the width of user's eye;
• determining a viewpoint corresponding to each of the multiple position coordinates according to display pictures viewed at the multiple position coordinates, and creating a database for a corresponding relationship between user's position and viewpoints where user's left eye and the right eye are located according to the multiple position coordinates and the viewpoints corresponding to the multiple position coordinates;
• a human face recognition camera for detecting the position of a user;
• a viewpoint determination unit for determining, by querying the database, 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 timing controller for turning on sub-pixels corresponding to the determined viewpoints at which the left eye and right eye of the user are located, in a display panel of the naked eye 3D display apparatus and turning off other sub-pixels in the display panel.
