A kind of liquid crystal lens and display device

Abstract

The invention discloses a liquid crystal lens and a display device, comprising an upper substrate, a lower substrate, a liquid crystal layer, a first transparent electrode, a second transparent electrode and a control unit; wherein, the first transparent electrode is a planar electrode; the second transparent electrode Divided into a plurality of electrode groups, each electrode group includes a plurality of sub-electrodes arranged in parallel and extending along the vertical direction. In the three-dimensional display mode, the control unit applies the first voltage to the sub-electrodes in each electrode group to control the deflection of the liquid crystal molecules in the regions corresponding to each electrode group in the liquid crystal layer to form a lenticular lens structure corresponding to the electrode group one-to-one, realizing three-dimensional Display function. In the curved surface display mode, the control unit applies a second voltage to the sub-electrodes in each electrode group to control the deflection of the liquid crystal molecules in the liquid crystal layer corresponding to each electrode group to form a microprism structure, and control the light to flow in each microprism structure The difference in the equivalent optical path of the prism is used to compensate the difference in optical path from the position of the viewer to each microprism structure, so as to realize the curved surface display.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal lens and a display device. Background technique [0002] In recent years, curved display has become a high-end product in the display field due to its advantages such as arc shape, wider viewing angle, embracing feeling and conformity to human visual structure. However, curved surface display products produced by physical methods also have unavoidable disadvantages, for example, it is inconvenient to hang on the wall and easily damaged when bent. At present, there are already display products that use liquid crystal lenses to realize naked-eye three-dimensional (3D) display, but there is no device that uses flat display to realize the combination of curved surface and 3D. Contents of the invention [0003] In view of this, an embodiment of the present invention provides a liquid crystal lens and a display device, which are used to realize the combination of t...
