Abstract

Provided are a 2D / 3D switching apparatus and a display device. The 2D / 3D switching apparatus comprises a switching layer (4) which comprises a cylindrical lens grating and a cavity body enclosed by a cylindrical curved surface of the cylindrical lens grating and a cover body; a liquid storage tank (2) used for storing a transparent liquid, the refractive index of the transparent liquid being identical to that of the material of the cylindrical lens grating; and a vacuum pump (5) which is connected to the cavity body of the switching layer and the liquid storage tank, respectively, and is used for pouring the transparent liquid from the liquid storage tank into the cavity body of the switching layer or pouring the transparent liquid from the cavity body into the liquid storage tank. Compared with a 2D / 3D switching apparatus in the prior art, the switching apparatus provided is simple in structure and is easy to achieve.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a 2D / 3D switching device and a display device including the 2D / 3D switching device. Background technique [0002] With the advancement of digital image processing technology and equipment manufacturing level, 3D display has become a popular trend in the display industry. The basic principle of the current 3D display is "parallax produces stereo", through certain facilities or technologies, the viewer can see different images in both eyes, that is, the left eye only sees the left eye image, and the right eye only sees the right eye image, and the left eye only sees the right eye image. The eye diagram and the right eye diagram are taken from two angles of a certain space scene. The left eye diagram and the right eye diagram are collectively called a stereo image pair. The human brain will fuse the two images seen by the two eyes. Thus producing a 3D effect. [0003] In ...
