Anti-peep system and method for automatically adjusting backlight angle of display screen based on angle of human eyes and screen

Abstract

The invention discloses an anti-peep system and a method for automatically adjusting a backlight angle of a display screen based on an angle of human eyes and the screen. The system comprises a mobile phone body, the display screen and a circuit board, wherein the display screen and the circuit board are installed in the mobile phone body. The circuit board is provided with a mobile phone central processing unit (CPU), a microprocessor chip, a vision sensor and an angle sensor. The display screen is connected with the mobile phone CPU through a backlight source. The mobile phone CPU is connected with the vision sensor and the angle sensor through the microprocessor chip. According to the system and the method, through inductive measurement for the angle of the user eyes and the screen, a vision angle of the human eyes and the screen is obtained, an angle of an emergent light of the backlight source of the mobile phone is calculated according to the vision angle, and a liquid crystal molecular angle of the display screen is correspondingly deflected and is in fit with the vision angle of the human eyes. Compared with the prior art, the system and the method can effectively solve the problem that due to the fact that a visual angle of an existing mobile phone screen is large, privacy of the mobile phone is easy to peep by other persons.

Description

technical field [0001] The invention belongs to smart phones, and in particular relates to an anti-peeping system and method for automatically adjusting the backlight angle of a display screen based on the angle between human eyes and the screen. Background technique [0002] The viewing angle of the mobile phone screen refers to the angle at which users can clearly observe all content on the mobile phone screen from different directions. Since the light source of the mobile phone screen has a certain directionality after refraction and reflection, color distortion will occur when viewing beyond this range. The viewing angle determines the viewing range of the mobile phone user to the screen and the best viewing angle. If it is too small, the user will slightly deviate from the front of the screen, and the picture will lose color. With the rapid development of communication technology and display technology, the viewing angle of mobile phone screens is getting larger and l...
