Abstract

The present invention provides a 3D grating, a color filter substrate, a display device and a control method thereof. The 3D grating includes: a first transparent electrode layer, a second transparent electrode layer, and a layer formed on the first transparent electrode layer and the second transparent electrode layer. An electrochromic material layer between two transparent electrode layers; wherein, the first transparent electrode layer includes a strip electrode pattern; the strip electrode pattern includes strip electrodes arranged at equal intervals and connected to the strip electrode pattern The electrode lines of each strip electrode; the electrochromic material layer is opaque in the electric field and transparent in the non-electric field. In the present invention, by controlling the applied voltage state of the first transparent electrode layer and the second transparent electrode layer, the 3D grating can be made transparent as a whole to realize 2D display or partially opaque as a grating to realize naked-eye 3D display. Sampling the 3D grating provided by the present invention can make the structure of the corresponding display device simple, and the 2D / 3D switching process is easy to realize.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a 3D grating, a color filter substrate, a display device and a control method thereof. Background technique [0002] Due to the development of display technology, 3D technology has become the mainstream of future display. At present, there are mainly two types of conversion methods for existing 2D / 3D stereoscopic display devices: the first type is to realize 2D through mechanical movement of lens sheets on the display panel. / 3D conversion, but this kind of device that realizes the principle of mechanical conversion is relatively large, and is easily affected by vibration, humidity, dust and other factors and is not easy to control. The other is to use liquid crystal lenses to produce different refractive indices for ordinary light (o light) and extraordinary light (e light), change the polarization direction of light, and finally realize the conversion of 2D / 3D display effect. ...
