Embodiment Construction

[0040] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0041] A specific embodiment of the present invention is a method for controlling a 3D display device. The 3D display device includes a display panel for displaying 2D images and a grating structure for cooperating with the display panel to form a 3D display effect, wherein the control method includes:

[0042] In the first period of time when a frame of image is output, the first control signal is output, so that the user's left eye can see the first effect of the first view on the display panel through the grating structure, and the user's right eye can see the first effect of the first view through the grating structure. viewing the first effect of the second view on the display panel;

[0043] In the second period of time when a fram...

Abstract

The invention provides a 3D display device, a control method and control device of the 3D display device. The control method includes the following steps that: first control signals are outputted at a first time period of the output of one frame of image, and therefore, the left eye of a user can observe a first effect of a first view on a display panel through a grating structure, and the right eye of the user can observe a first effect of a second view on the display panel through the grating structure; and second control signals are outputted at a second time period of the output of one fame of image, and therefore, the left eye of the user can observe a second effect of a first view on the display panel through the grating structure, and the right eye of the user can observe a second effect of a second view on the display panel through the grating structure. With the control method of the invention adopted, the left eye and right eye of the user can see more image information, and therefore, the PPI (pixel per inch) of a 3D display effect can be improved.

Description

technical field [0001] The present invention relates to the technical field of 3D display, in particular to a control method of a 3D display device, a control device and a 3D display device. Background technique [0002] With the advancement of science and technology, the use of 3D stereoscopic display technology in real life is becoming more and more common. Since naked-eye 3D technology can watch 3D effects without using 3D glasses, it has better promotion and application prospects, and has become the research focus of many stereoscopic display manufacturers. [0003] Existing glasses-free 3D technologies mainly include three types: light barrier type, lenticular lens type and pointing light source type. Among them, for the light barrier type 3D display device, the PPI (pixelsperinch, the number of pixels per inch, that is, the unit of image resolution) is relatively low, which affects the 3D display effect. Contents of the invention [0004] The purpose of the technic...
