Problems solved by technology

[0005] The above-mentioned 3D display principle is only a false 3D display method, and there are intractable defects such as display adjustment and vergence mismatch, dizziness and display dead zone.
[0006] At present, there are also studies on true 3D display technology, such as holographic three-dimensional display, but the display device using this principle has a complex structure and is currently difficult to commercialize

Abstract

The invention provides a 3D (three-dimensional) display device and a display drive method thereof. The 3D display device comprises a display panel for outputting a two-dimensional display image, a depth data extraction device and a refractive index adjusting device, wherein the depth data extraction device is used for acquiring depth data of each pixel unit of the current frame of the outputted display image of the display panel; the refractive index adjusting device is arranged on a light emitting side of the display panel and used for refracting the light transmitted by the display panel through each pixel unit, so that the refractive index of the refracted light passing by the refractive index adjusting device is in direct proportion to the depth data. The display device is provided with the depth data extraction device and the refractive index adjusting device, so that the display light of the display image outputted by the display panel is refracted, the refractive index is in direct proportion to the depth value of the corresponding pixel unit when in two-dimensional display, thus for the display picture of the current frame, objects in different distances can be seen by a viewer, a stereoscopic impression can be generated, and a real three-dimensional display effect can be presented.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a 3D display device and a display driving method thereof. Background technique [0002] The difference between 3D display and 2D display is to use various methods to bring visual depth perception to the viewer, so that it can naturally or unnaturally obtain the third-dimensional information in the picture. This perception method is true 3D and false to the human eye. 3D difference. Therefore, for 3D stereoscopic imaging technology, it is very important to restore the real physical depth of field in 3D stereoscopic space, and it is also the most critical factor for human eyes to perceive 3D stereoscopic images. [0003] In the current 3D display devices, the commonly used display principle is not true 3D. Usually, the stereograms of the real scene are obtained by simulating the human eyes, and then the stereograms are displayed on the display device, and then the viewer'...
