Embodiment Construction
[0020] attached figure 1 It is a cross-sectional view of an embodiment of a grating 2D / 3D switchable display device of the present invention in a 2D display mode. Refer to attached figure 1 , the device consists of an anamorphic lenticular lens grating and a liquid crystal display 09, and its sub-pixel horizontal width parameter is 0.0090mm. Wherein, the deformed cylindrical lens grating includes a colorless and transparent first liquid 01, a colorless and transparent second liquid 02, a colorless and transparent elastic film 03, a first support plate 11, a second support plate 12, a colorless and transparent first liquid A container 04, a second container 05, a first pipe 06, a second pipe 07, a piston 08 and a pulling rod 10 connected to the piston. Both the first container 04 and the second container 05 contain the immiscible first liquid 01 and the second liquid 02, the elastic film 03 isolates the first liquid 01 and the second liquid 02 in the first container, and the ...

The invention provides a grating two-dimensional / three-dimensional (2D / 3D) switchable display device. The device mainly comprises a deformation columnar lens grating and a 2D display, wherein two types of transparent liquid which cannot be mixed and dissolved are filled in the deformation columnar lens grating; the refractive indexes of the two types of transparent liquid are different and the densities are similar or the same; the two types of transparent liquid are separated by a transparent elastic thin film; two surfaces of the elastic thin film are supported by a plurality of transparentsupporting boards; the deformation of the elastic thin film is realized and controlled by driving the liquid to flow under an external force under the supporting of the supporting boards; and the deformation of the elastic thin film comprises a planar shape and a columnar shape. When the device is switched to a 2D mode, the elastic thin film is deformed into the planar shape and the deformation columnar lens grating is free from a function of a lens and used for 2D displaying; and when the device is switched to a 3D mode, the elastic thin film is deformed into the columnar shape and the deformation columnar lens grating has the function of the lens and is used for 3D displaying.
Description
technical field [0001] The device of the present invention relates to a display device, more specifically, to a display device switchable between a two-dimensional (2D) mode and a three-dimensional (3D) mode. Background technique [0002] The grating 3D display device is a stereoscopic display device in which viewers can watch 3D images without wearing auxiliary equipment, and it is composed of a flat display and a grating. Multiple parallax images are synthesized into a stereoscopic image with sub-pixels as a unit according to a certain rule and displayed on a flat-panel display. The flat-panel display is precisely coupled with the grating. The light propagates in different directions. When the viewer is located in a suitable viewing area, the left and right eyes see different parallax images. According to the principle of binocular parallax, the viewer can watch images with a three-dimensional effect. Common gratings include slit grating and cylindrical lens grating, amon...
