Anti-peep device and manufacturing method thereof, and display device

Abstract

The invention discloses an anti-peep device and a display device. The anti-peep device includes a transparent substrate, multiple first electrodes on the substrate, a transparent insulation body on the substrate, and multiple second transparent electrodes which are formed at concave portions of the insulation body and partially surround the first electrodes, wherein the insulation body has the multiple concave portions in one-to-one correspondence with the first electrodes, openings of the concave portions face the substrate, the first electrodes are arranged in the concave portions, the widthof cross sections of the concave portions tapers in a direction away from the substrate, the sealing space is defined among the insulation body, the second electrodes and the substrate, the electrophoretic solution is accommodated in the sealing space, the electrophoretic solution includes reflective charged particles, and the reflective charged particles are suitable for attaching to the secondelectrodes when a first electric field is applied between the first electrodes and the second electrodes. The anti-peep device is advantaged in that the anti-peep effect can be realized, and user experience is improved.

Description

technical field [0001] Embodiments of the present disclosure relate to an anti-peeping device, a manufacturing method thereof, and a display device with the anti-peeping device. Background technique [0002] With the rapid development of display technology, the light output angle of existing displays is very large, and the maximum light output angle even reaches 178°, such as the ADS display screen. Such a large viewing angle brings consumers an excellent user experience in some applications such as TV product applications, but in some applications such as personal mobile products or special applications, it will cause leakage of personal information or privacy. [0003] In response to this problem, anti-peeping devices for displays have been proposed, such as the anti-peeping film of 3M Company, in order to achieve the convergence of display angles. However, the existing anti-peeping devices have problems such as inconvenient to carry, inability to switch between the anti-...

AI Technical Summary

Problems solved by technology

However, the existing anti-peeping devices have problems such as inconvenient to carry, unable to switch between the anti-peeping mode and non-peeping-proof mode, and the brightness of the display in the anti-peeping mode is not enough.
