Problems solved by technology

[0004] The inventors have found that there are at least the following problems in the prior art: in the existing stereoscopic display devices, no matter whether the slit grating or the lens grating is used, the grating structure needs to be attached to the light-emitting surface side of the display device. This attachment process increases the preparation process and production cost to a certain extent; at the same time, because the accuracy of the attachment process is also limited, the rate of poor attachment is relatively high

Embodiment 1

[0026] Such as figure 1 As shown, the present embodiment provides a polarizer, which includes a polarizer original film layer 1, and a grating layer 2 arranged on the light-emitting surface side of the polarizer original film layer 1, and the grating layer 2 has a plurality of alternately arranged The light-shielding area b and the light-transmitting area a, the light-shielding area b is provided with a photochromic layer for changing to a light-shielding state when light is irradiated; the light-transmitting area a is provided with a light-transmitting layer.

[0027] Since the polarizer in this embodiment has a grating layer 2, the function of naked-eye 3D display can be realized by pasting the polarizer layer on the light-emitting surface side of the display panel. The grating layer 2 is separately provided on the light-emitting surface side of the display panel, thereby saving the process flow of preparing a naked-eye 3D display device and improving production efficiency; ...

Embodiment 2

[0039] This embodiment provides a display device, which includes the polarizer described in Embodiment 1. Therefore, when there is light irradiation, the photochromic layer is in a light-shielding state, and the display device displays a 3D image at this time; when there is no light irradiation, the photochromic layer is in a light-transmitting state, and the display device displays a 2D image at this time .

[0040] It should be noted that the nature of the illumination is different from the light of the backlight of the display device, otherwise the display device can only realize 2D display or 3D display, and cannot realize switching between 2D and 3D.

[0041] In the display device of this embodiment, a synchronous light source control module is further included, and the synchronous light source control module is used to emit light of a single wavelength to control the opening and closing of the grating layer 2 . Among them, the synchronous light source control module dir...

Abstract

The invention provides a polarizer sheet and a display device, belongs to the technical field of display, and can solve the problems of low yield and complex process caused by attachment of an existing optical grating layer to the emergent surface side of a display panel. The polarizer sheet comprises a polarizer sheet original film layer, and an optical grating layer arranged on the emergent surface side of the polarizer sheet original film layer, wherein a plurality of shading regions and light transmission regions are alternatively arranged on the optical grating layer; photochromic layers used for shading light during irradiation are arranged in the shading regions; light transmission layers are arranged in the light transmission regions. The polarizer sheet is applied to the display device and can realize 2D and 3D image switching display.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a polarizer and a display device. Background technique [0002] Currently, the commonly used displays all adopt two-dimensional display, which cannot intuitively express the depth information of the scene. With the development of computer information technology and display technology, three-dimensional display technology has become a research focus in the field of display. Because it can completely reproduce the three-dimensional space information of the scene, the viewer can see the objects floating out of the screen and extending into the depth. , three-dimensional images suspended in the air. [0003] Autostereoscopic display technology refers to a display technology in which a stereoscopic effect can be observed through the naked eyes of the viewer without wearing any auxiliary viewing tools. Among many stereoscopic display technologies, grating autostereoscopi...
