Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0035] figure 1 is a schematic structural diagram of a liquid crystal lens provided by an embodiment of the present invention, as shown in figure 1 As shown, the liquid crystal lens may include: a first electrode 01, a second electrode 02 opposite to the first electrode 01, and a liquid crystal layer 03 between the first electrode 01 and the second electrode 02; A third electrode 04 is formed on the side of the electrode 01 away from the liquid crystal layer 02 .

[0036] In 3D display mode, refer to figure 2 Applying a voltage to the first electrode 01 and the second electrode 02 generates an electric field, so that the liquid crystal molecules in the liquid crystal layer 03 form a plurality of lens units, and each lens unit functi...

Abstract

The invention discloses a liquid crystal lens and a display device, belonging to the technical field of display. The liquid crystal lens comprises a first electrode, a second electrode arranged opposite to the first electrode, and a liquid crystal layer positioned between the first electrode and the second electrode; a third electrode is formed at the side, far away from the liquid crystal layer, of the first electrode; when in a three-dimensional (3D) display mode, an electric field is generated by applying voltage onto the first electrode and the second electrode, so that a plurality of lens units are formed by liquid crystal molecules in the liquid crystal layer; when the 3D display mode is switched to a two-dimensional (2D) display mode, an electric field is generated by applying voltage onto the first electrode and the third electrode, so that the liquid crystal molecules in the liquid crystal layer are deflected to an initial state; the liquid crystal molecules which are in the initial state do not have a regulating effect on incident polarized light. Compared with the related technologies, the liquid crystal lens accelerates the switching response speed of the display device when the display device is switched to the 2D display mode from the 3D display mode. The liquid crystal lens and the display device are used for 3D 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] With the rapid development of display technologies, naked-eye three-dimensional (English: Three Dimensional; 3D for short) display devices are becoming more and more popular. The naked-eye 3D display device is equipped with a liquid crystal lens on the light-emitting side of the display panel, and uses the liquid crystal lens to form several viewing areas on the light-emitting side of the display panel, so that the light emitted by different sub-pixels on the display panel falls in different viewing fields, and the viewer's The sight lines of the left eye and the right eye respectively falling in different fields of view can make the viewer feel 3D. [0003] In related technologies, a liquid crystal lens is generally composed of an upper substrate, a lower substrate, and a liquid crystal layer disposed be...
