Embodiment 1

[0033] Such as Figure 1 to Figure 6 As shown, among them, Figure 4 to Figure 6 for image 3 Schematic cross-section along A-A. This embodiment provides an anti-peeping structure, including:

[0034] The anti-peeping layer 1 includes a plurality of light-transmitting parts 11 and a plurality of light-transmitting parts 12, each of the light-transmitting parts 11 and the light-proof parts 12 is annular, and all the light-transmitting parts 11 and the light-proof parts 12 are concentric distribution, and an opaque portion 12 is distributed between any two adjacent light-transmitting portions 11, the light directed to the first surface 13 of the anti-peeping layer 1 can pass through the light-transmitting portion 11, but cannot pass through the opaque portion part 12, so that at least part of the light is emitted from the second surface 14 of the anti-peeping layer 1 at a predetermined angle.

[0035] Wherein, that is to say, the anti-peeping layer 1 is formed by a light-tra...

Embodiment 2

[0077] Such as Figure 1 to Figure 6 As shown, this embodiment provides a display device, including:

[0078] The backlight module has a light incident side and a light output side;

[0079] The display structure is arranged on the light emitting side of the backlight module;

[0080] The anti-peeping structure in Embodiment 1 is arranged on the light emitting side of the backlight module.

[0081] Wherein, that is to say, based on the performance of the anti-peeping structure, disposing the anti-peeping structure in the display device can enable the display device to have an anti-peeping function in various directions, thereby improving the anti-peeping effect of the display device.

Abstract

The invention provides a peep-proof structure and a display device, belongs to the technical field of display, and can at least partially solve the problem of poor peep-proof effect of the existing display device. The peep-proof structure provided by the invention comprises a peep-proof layer including a plurality of light-transmitting portions and a plurality of opaque portions, wherein each of the light-transmitting portions and the opaque portions is in the shape of a ring, all the light-transmitting portions and the opaque portions are concentrically distributed, an opaque portion is distributed between any two adjacent light-transmitting portions, and the light directed to the first surface of the peep-proof layer can pass through the light-transmitting portions, but cannot pass through the opaque portions, so that at least part of the light is emitted from the second surface of the peep-proof layer at a predetermined angle.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to an anti-peeping structure 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 when they are riding or waiting for a bus. However, due to the large number of people on board, users The content displayed on your mobile phone or tablet computer may be peeped by neighbors, and the information may be leaked, resulting in the user's privacy not being protected and causing inconvenience to the user. [0003] In order to prevent the content displayed on the user's display device (mobile phone or tablet computer) from being peeped by the neighbors, in the display device of the prior art, a peep-proof layer is provided on the light-emitting side to prevent the content displayed on the di...
