Abstract

The invention provides a three-dimensional display device which comprises a displayer, a camera and a processor. The camera which is arranged on a front end face of the displayer is used for tracking human eye location information; the processor which is electrically connected with the camera is used for generating control signals according to the human eye location information; the displayer comprises a dynamic optical grating which is electrically connected with the processor; and the dynamic optical grating is used for controlling on-off of alternating voltages between different ITO (Indium Tin Oxide) electrodes and a first ITO conductive layer in the dynamic optical grating according to the control signals to enable positions of light and dark strips of the dynamic optical grating to produce adaptive changes to adapt to human eye positions to enable a left eye image which is displayed through the displayer to reach a left eye of a person through the dynamic optical grating and a right eye image which is displayed through the displayer to reach a right eye of the person through the dynamic optical grating. Accordingly, the three-dimensional display device has the advantage of achieving a 3D (Three Dimensional) image viewing effect due to the facts that the camera is utilized to track the human eye location information and then a control unit is utilized to achieve changes of the positions of the dynamic optical grating to adapt to different observation positions of human eyes according to the human eye location information.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a stereoscopic display device. Background technique [0002] In the current grating technology, after the grating is manufactured, the position of the light and dark stripes of the grating will be fixed, which brings inconvenience to our work, especially when using the parallax barrier technology to realize the stereoscopic image display, because the position of the light and dark stripes of the grating is uncontrollable, The 3D image effect can only be viewed by restricting the viewer's eyes within a specific range, which affects the application of the parallax barrier stereoscopic display technology in daily life. [0003] Therefore, it is necessary to provide a stereoscopic display device to solve the above technical problems. Contents of the invention [0004] The present invention mainly provides a stereoscopic display device, which uses a camera to track the position in...
