Abstract

The embodiment of the invention provides a peep-proof film and a display device, relates to the technical field of peep-proof display, and can solve the problem that the light emitting angle of a display panel is large. The peep-proof film is arranged on the light emitting side of the display panel, the display panel comprises a black matrix, and the peep-proof film comprises: a substrate; a transparent dielectric layer which is positioned on the substrate, the surface, close to the substrate, of the transparent dielectric layer is provided with a plurality of grooves which are recessed towards the side away from the substrate and are arranged at intervals; and a plurality of light absorption structures which are used for absorbing light rays irradiated to the light absorption structures,wherein the light absorption structures are arranged in the groove and are in contact with the substrate, and at least one part of the vertical projections of the light absorption structures on the substrate is overlapped with at least one part of the vertical projection of the black matrix on the substrate. The peep-proof film and the display device are used in the peep-proof display device.

Description

technical field [0001] The present application relates to the technical field of anti-peeping display, in particular to an anti-peeping film and a display device. Background technique [0002] With the development of display technology, the light output angle of the display mode of the current display device is very large, and the ADS (Advanced Super Dimension Switch, advanced super dimension field switching technology) display mode can even reach 178°. When users use it in public places or need to In the scenario of privacy protection, there is a risk of personal information and privacy leakage, resulting in poor user experience. Contents of the invention [0003] Embodiments of the present application provide an anti-peeping film and a display device, which can solve the problem of a large light emitting angle of a display panel. [0004] In order to achieve the above object, the embodiments of the present application adopt the following technical solutions: [0005] I...
