Embodiment 1

[0033] This embodiment provides an anti-peeping structure, including:

[0034] at least one transmissive region for transmitting light impinging thereon;

[0035] And at least one peep-proof area, the peep-proof area includes a peep-proof device, and the peep-proof device is used to perform peep-proof treatment on the light incident on it.

[0036] Anti-peeping processing means that the viewing angle is very small, and the display content can only be seen clearly from a certain angle, and it is blurred from other angles.

[0037] In the anti-peeping structure of this embodiment, at least one anti-peeping area and at least one transmission area are set, and the anti-peeping area can perform anti-peeping treatment on the light incident on it, such as changing the direction, polarization direction, brightness, etc. of light, while its Without affecting the transmission of light in the transmission area, using the anti-peeping structure of the present invention in a display devic...

Embodiment 2

[0039] Such as Figure 1-3 As shown, the present embodiment provides an anti-peeping structure 1, including:

[0040] at least one transmissive area 12 for transmitting light impinging thereon;

[0041] And at least one peep-proof area 11, the peep-proof area 11 includes a peep-proof device 110, and the peep-proof device 110 is used to perform peep-proof treatment on the light incident on it.

[0042] That is to say, at least one peep-proof area 11 and at least one transmission area 12 are set in the anti-peeping structure 1 of this embodiment, the anti-peeping area 11 can prevent peeping, and it does not affect the light transmission of the transmission area 12 at the same time. The anti-peeping structure 1 of the present invention is used in a display device to realize anti-peeping display in a part of the display area of ​​the display screen, and normal display in another part of the display area of ​​the display screen. The anti-peeping structure 1 of the present inventi...

Embodiment 3

[0049] Such as Figure 1-3 As shown, the present embodiment provides a display panel 2 which includes the anti-peeping structure 1 of the second embodiment.

[0050] That is, the anti-peeping structure 1 can be arranged on the surface of the display panel (on cell), or it can be arranged in the display panel 2 and become a part of the display panel 2 .

[0051] Preferably, the anti-peeping structure 1 is arranged on the light emitting side of the display panel 2 .

[0052] That is to say, the anti-peeping structure 1 is set on cell, which is a relatively preferred setting method, so that it is convenient to flexibly control the anti-peeping structure 1 when touched.

[0053] Preferably, the display panel includes any one of an OLED panel, an electronic paper display panel or a liquid crystal display panel, and the anti-peeping structure is arranged on the light-emitting side of the display panel. Preferably, the display panel 2 is a touch display panel.

[0054] The display...

Abstract

The invention provides an anti-peeping structure, a display panel, a backlight module and a display device, which belong to the field of display technology and can solve the problem that existing display devices cannot realize anti-peeping in part of the display area. The anti-peeping structure of the present invention includes at least one transmission area for transmitting light incident thereon; and at least one anti-peeping area, the anti-peeping area includes an anti-peeping device for Provides a privacy treatment for the light that hits it. The anti-peeping structure of the present invention is provided with at least one anti-peeping area and at least one transmission area. The anti-peeping area can perform anti-peeping treatment on light without affecting the transmission of light in the transmission area. The anti-peeping structure of the present invention When used in a display device, anti-peeping can be realized in a part of the display area of ​​the display screen. The anti-peeping structure of the present invention is applicable to various display panels, backlight modules and display devices.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to an anti-peeping structure, a display panel, a backlight module and a display device. Background technique [0002] With the advancement of technology, portable display devices are becoming more and more popular. For example, people usually use mobile phones or tablet computers to read, study or communicate with text messages when they are riding or waiting for a bus. The content displayed on the mobile phone or tablet computer may be peeped by the neighbors, and the information may be leaked, resulting in the privacy not being protected and causing inconvenience to the user. At present, the privacy of one's own privacy is usually protected by pasting anti-spy sheets on the display device in the market. [0003] The inventors have found at least the following problems in the prior art: the anti-peeping display of the display device in the prior art is aimed at the en...
