Problems solved by technology

[0003] The naked-eye stereoscopic display device has the advantages of not having additional peripherals such as glasses, allowing users to watch in a more free environment; however, the display area of ​​the current naked-eye stereoscopic display technology is relatively fixed, and viewers can only watch in the stereoscopic viewing area. to a more suitable stereo image
Obtain the audience's position through the tracking device, and then modify the view information of the stereoscopic image arrangement in real time, so that the audience can always see the correct stereoscopic effect, but it will introduce the influence of crosstalk

Abstract

The invention discloses a three-dimensional display device, a control method of the three-dimensional display device and a controller. The three-dimensional display device comprises a tracking device for obtaining an watching position, a controllable light splitter, a driving circuit and a display panel, wherein the controller is used for obtaining the watching position according to the tracking device so as to calculate the offset of the controllable light splitter and controlling the driving circuit to move the controllable light splitter according to the calculated offset. According to the invention, the limitation of the watching zone is eliminated, and the parallel movement of the watching zone relative to the screen is implemented.

Description

technical field [0001] The invention relates to the field of stereoscopic display, in particular to a stereoscopic display device, a control method and a controller thereof. Background technique [0002] A stereoscopic display device uses the parallax feature of human eyes to present a stereoscopic image with spatial depth information, and usually synthesizes multiple views with parallax through a pixel arrangement algorithm and outputs them to a stereoscopic display. This disparity map is directly transmitted to the left and right eyes of the viewer, and then a stereoscopic image is synthesized. [0003] The naked-eye stereoscopic display device has the advantages of not having additional peripherals such as glasses, allowing users to watch in a more free environment; however, the display area of ​​the current naked-eye stereoscopic display technology is relatively fixed, and viewers can only watch in the stereoscopic viewing area. to a more suitable stereoscopic image.
