Problems solved by technology

[0003] However, for users, the current naked-eye display technology makes users feel the obvious 3D effect only by observing holographic stereoscopic display images or videos from one or more fixed orientations and angles, while observing from other orientations and angles. Can't feel the obvious 3D effect

Abstract

The invention discloses a mobile terminal and a method for holographic three-dimensional display self-adaptive to free views of multiple users. The terminal comprises a tracking and positioning device, an angular adjustment circuit and a multi-area holographic three-dimensional display screen, wherein the tracking and positioning device is used for obtaining position information of at least two observers and a number of observers; the angular adjustment circuit is used for computing a ray casting angle and three-dimensional pictures of viewpoints of a left eye and a right eye which are corresponding to the position information of each observer; the multi-area holographic three-dimensional display screen is provided with a plurality of user-defined pixels, and each user-defined pixel comprises sub display areas which have the same number as the observers, and is used for adjusting the ray casting angle of each sub display area, so that each user-defined pixel is provided with the corresponding sub display area for each observer, and ray emitted by the corresponding sub display area is corresponding to the ray casting angle of the corresponding position information to project the corresponding three-dimensional pictures of the viewpoints of the left eye and the right eye. According to the mobile and the method, the positions and the number of the observers are firstly determine, and then the holographic three-dimensional display is carried out, so that the holographic three-dimensional display self-adaptive to the free views on the holographic three-dimensional display terminal is implemented, and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a mobile terminal and a method for adaptively realizing holographic stereoscopic display with a free viewing angle. Background technique [0002] At present, stereoscopic (3D or three-dimensional) display technologies mainly include glasses-wearing and glasses-free naked-eye display technologies. Although the wearable glasses-type display technology is mature, it is necessary to wear special glasses to watch 3D videos or images, which brings a lot of inconvenience to people. Therefore, naked-eye display technology is widely used for its convenient viewing method. According to the display principle, it can be divided into three-dimensional, integrated imaging, holographic and parallax barrier display technologies. The traditional imaging method is to synthesize several sub-viewpoint pictures into one frame of images, and display them on the LCD screen at the same...
