Liquid crystal lens and display device

Abstract

The invention discloses a liquid crystal lens and a display device. The liquid crystal lens comprises an upper substrate, a lower substrate, a liquid crystal layer, a first transparent electrode, a second transparent electrode and a control unit; the first transparent electrode is a planar electrode; the second transparent electrode is divided into a plurality of electrode sets, and each electrode set comprises a plurality of sub electrodes which are parallel to one another and extend in the vertical direction. Under a three-dimensional display mode, the control unit exerts first voltage on the sub electrodes in all the electrode sets, liquid crystal molecules in areas corresponding to all the electrode sets in the liquid crystal layer are controlled to generate deflection to form columnar lens structures in one-to-one correspondence with the electrode sets, and the three-dimensional display function is achieved. Under a curved-surface display mode, the control unit exerts second voltage on the sub electrodes in all the electrode sets, liquid crystal molecules in areas corresponding to all the electrode sets in the liquid crystal layer are controlled to generate deflection to form microprism structures, difference of the equivalent optical path of light rays in all the microprism structures is controlled so as to compensate the optical path difference between the position of a viewer and all the microprism structures, and curved-surface display is achieved.

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...
