Problems solved by technology

However, for a display device with a wide viewing angle mode, the anti-peep performance in the direction of the up and down viewing angles is poor, so that the display device cannot achieve good anti-peeping performance in all viewing angle directions.

Embodiment Construction

[0022] In order for those skilled in the art to better understand the technical solution of the present invention, the privacy film provided by the present invention, its manufacturing method and display device will be described in detail below with reference to the accompanying drawings.

[0023] figure 1 A schematic structural view of a privacy film provided in Embodiment 1 of the present invention, as shown in figure 1 As shown, the anti-peeping film includes: a main structure 11 and a light gathering structure 12 located in the main structure 11 . The refractive index of the main structure 11 is different from that of the light converging structure 12, so that the incident light is converging and emitted.

[0024] In this embodiment, the refractive index of the main structure 11 is greater than the refractive index of the light converging structure 12 . Specifically, the width of the light incident side close to the main structure 11 of the light converging structure 12 ...

Abstract

The invention discloses a peep-proof membrane, a manufacture method and a display device. The peep-proof membrane comprises a main body structure and a light ray convergence structure. The refractive index of the main body structure and the refractive index of the light ray structure are different in order to make the incident light to emit after convergence. In the schemes of the peep-proof membrane and the display device, the light convergence structure is positioned in the main body structure, the refractive index of the main body structure and the refractive index of the light ray convergence structure are different, which enables the incident light to emit after convergence, improves the peep prevention from the upper visual angle and the lower visual angle and realizes the fact that the display device has good peep-proof performances from all visual angles.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a privacy film, a manufacturing method thereof, and a display device. Background technique [0002] As mobile display devices, such as notebooks, tablet computers, smart phones, etc. are more and more widely used, some groups require privacy protection on mobile display devices due to their privacy. [0003] At present, the anti-spy film is usually an ultra-fine louver-type anti-spy film, which has good anti-peep performance in left and right viewing angles, and can be widely used in display devices with narrow vertical viewing angles. However, for a display device in a wide viewing angle mode, the anti-peep performance in the up and down viewing angle directions is relatively poor, so that the display device cannot achieve better anti-peeping performance in all viewing angle directions. Contents of the invention [0004] The invention provides an anti-peeping film, a manufac...
