The viewing angle of the anti-peep film is usually the middle of the screen, with a viewing angle of 30 to 45 degrees on the left and right sides. The angle outside the viewing angle is an invisible angle (area); the smaller the viewing angle, The larger the anti-spy angle, the better the anti-spying effect.
