Visual angle setting system and method for liquid crystal display screen

The present invention provides a viewing angle setting method for setting an electronic device LCD viewing angle. The method comprising: obtaining recognition reference; receiving preset LCD viewing angle; identified with reference to the above-described face recognition to match faces in the image pickup apparatus for electronic equipment currently captured; calculated recognition angle vertical line of the center of the face and eyes, the center of the connection between the LCD screen and the LCD screen between; calculated according to the angle of the LCD and the received viewing angle of liquid crystal molecules deflection required angle; deflection angle is calculated according to the voltage applied to the liquid crystal molecules in the liquid crystal display needs; and to the bus voltage is applied to both sides of the LCD screen according to the voltage value to change the viewing angle of the LCD screen. The present invention also provides a viewing angle setting system. The present invention can set the LCD viewing angle according to the individual needs of users.
