Abstract

The embodiment of the invention provides a liquid crystal lens, a display device and a control method thereof, and relates to the technical field of display. When the liquid crystal lens is applied to the display device, a 3D display effect compatible with landscape and portrait modes can be realized. The liquid crystal lens comprises a first base plate, a second base plate, a liquid crystal layer, a first electrode layer, a second electrode layer and a public electrode layer, wherein the liquid crystal layer, first electrode layer, second electrode layer and public electrode layer are positioned between the first and second base plates; the first electrode layer comprises a first strip electrode, the second electrode layer comprises a second strip electrode, the first strip electrode and second strip electrode are vertical without electric connection; and the first electrode layer and public electrode layer are used for driving the liquid crystal layer to form a first lens unit, and the second electrode layer and public electrode layer are used for driving the liquid crystal layer to form a second lens unit.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal lens, a display device and a control method thereof. Background technique [0002] With the continuous development of display technology, 3D (three-dimensional) display is favored by consumers for its real and vivid expressive force, elegant and elegant environmental appeal, and strong and shocking visual impact. Early 3D display devices require viewers to wear corresponding 3D glasses, so that their wide application is limited by places and equipment. The glasses-free 3D display device developed in recent years overcomes the defects of the early 3D display device and has attracted wide attention. [0003] There are two main ways to realize naked eye 3D: slit grating type and cylindrical lens grating type. Since the slit grating loses at least half of the brightness of the device, the cylindrical lens grating is superior to the slit grating type in terms of br...
