Adjusting method of visual angle of liquid crystal display, liquid crystal display and terminal

Abstract

The invention discloses an adjusting method of the visual angle of a liquid crystal display, the liquid crystal display and a terminal. The adjusting method is used for adjusting the visual angle of the liquid crystal display so as to protect individual privacy displayed on the display. The liquid crystal display comprises an adjusting module, a voltage control module and a liquid crystal molecule module, wherein a user uses the adjusting module for adjusting the visual angle of the liquid crystal display; the voltage control module is connected with the adjusting module and used for controlling an output voltage according to the visual angle input by the adjusting module; the liquid crystal molecule module is connected with the voltage control module and used for controlling arranging and turning-over of liquid crystal molecules according to the output voltage, so that the liquid crystal display is in the visual angle. By the adoption of the technical scheme, the visual angle of the liquid crystal display can be adjusted on occasions when the individual privacy needs to be protected, and the effect that content on the liquid crystal display cannot be seen by other people is achieved.

Description

technical field [0001] The invention relates to the field of electronic products, in particular to a method for adjusting the viewing angle of a liquid crystal display, a liquid crystal display and a terminal. Background technique [0002] As the screens of smartphones become bigger and bigger, functions and applications become more and more abundant, and applications such as information query, e-reading, Weibo and online payment are widely used, the security and privacy protection of personal information is very important. When using large-screen mobile phones in public places such as subways, buses, and elevators, it is easy for the information on the mobile phone to be peeped by people around, intentionally or unintentionally, seriously causing information leakage and privacy leakage. [0003] Existing solutions generally have the following two types: [0004] Solution 1: Add a polarizer with an anti-peeping film on the terminal, only the user can see the information at ...
