Embodiment Construction

[0034] The present disclosure will now be specifically described with reference to the following examples. It is noted that the following descriptions of some embodiments are presented herein for purposes of illustration and description only. It is not intended to be exhaustive or to be limited to the precise forms disclosed.

[0035]Traditional anti-peeping privacy devices typically utilize privacy protectors (eg, privacy filters manufactured by 3M). The privacy protector includes vertically arranged extremely fine microstructures, each of which is set perpendicular to the display screen. Once the privacy protector is installed on the display device, the display device can only operate in the privacy mode, and cannot switch between the privacy mode and the non-privacy mode. Display devices with privacy protectors have limited viewing angles. This design becomes very inconvenient for the user when the display needs to be shared with another person.

[0036] Therefore, the ...

Abstract

The present application discloses an anti-peeping device for switching the viewing angle of a display panel between a first viewing angle and a second viewing angle. The anti-peeping device comprises: a base substrate (61); a first liquid crystal layer (10) located on the base substrate (61); Two liquid crystal layers (20); a first controller, which is configured to control the first liquid crystal layer (10) to switch between light transmission and light blocking in a plurality of first regions (R1) separated from each other, while the first Other regions of a liquid crystal layer (10) are light-transmitting; and a second controller configured to control the second liquid crystal layer (20) in light-transmitting and Switching between light-blocking, while other areas of the second liquid crystal layer (20) are light-transmitting.

Description

technical field [0001] The present invention relates to display technology, and more particularly, to an anti-peeping device for switching the viewing angle of a display panel between a first viewing angle and a second viewing angle, a display device, a method for operating a display device, and manufacturing an anti-peeping device device method. Background technique [0002] Display devices such as mobile phones, desktop computers, and notebook computers have evolved to provide many functions. A user may use a display device to access various information including private information. For example, a user may use a display device to access bank accounts, pay bills, make online purchases, and access various password-protected websites. Users can be exposed to identity theft and privacy violations when they access private information in public places. Therefore, in recent years, privacy protection has become the focus of research and development of display technology. Con...
