Abstract

The invention discloses a dynamic grating for 2D-to-3D (two-dimension to three-dimension) conversion and a control method of the dynamic grating. The dynamic grating comprises a first control layer, a second control layer, a grating material and a control module. The first control layer comprises a first transparent substrate and a first transparent electrode. The second control layer comprises a second transparent substrate and a second transparent electrode. The second transparent electrode is a planar electrode and is arranged on the upper surface of the second transparent substrate. The grating material is arranged between the first control layer and the second control layer. The control module controls voltage between the first transparent electrode and the second transparent electrode and is used for adjusting the dynamic grating to be in a transparent state to realize a 2D display effect or adjusting the dynamic grating to have a nontransparent area and become a light and shade alternate grating to realize a 3D display effect. The dynamic grating for 2D-to-3D conversion has the advantages that the structure is simple, the cost is low, the 2D display and the 3D display can be simultaneously realized in different areas on a screen, the conversion switching between 2D and 3D is easy to realize and the using effect of display devices is improved.

Description

technical field [0001] The invention relates to the field of stereoscopic display, in particular to a dynamic grating for 2D / 3D conversion. Background technique [0002] Due to the development of display technology, 3D technology will become the mainstream of future display, and 3D stereoscopic display technology can be mainly divided into glasses-wearing and naked-eye types. Glasses-wearing 3D display can be realized through active shutter glasses and passive polarized glasses; naked-eye 3D display can be divided into parallax-shielding grating, lenticular lens and directional backlight. At present, 3D image resources are relatively scarce. If the mutual conversion between 2D and 3D modes can be realized according to the format of the displayed image, the use efficiency of the display device can be improved. Compared with a stereoscopic display device with only a single stereoscopic display function, a 2D / 3D switchable stereoscopic display device can allow users to freely ...
