  • Anti-peep display device and anti-peep method
    Patent number: 11966107
    Abstract: An anti-peep display device includes a display module and an anti-peep module disposed on the display module. The anti-peep module includes the following features. The first light incident surface faces the display surface, the second and third light incident surfaces are located on opposite sides of the first light incident surface, the first condensing portion is disposed corresponding to the second light incident surface and the first light source, the second condensing portion is disposed corresponding to the third light incident surface and the second light source, the first and second condensing portions convert beams of the first and second light sources into anti-peep beams with a beam angle less than 10 degrees, and the optical microstructures reflect the anti-peep beams and exit the anti-peep beams from the light guide plate. The present invention also provides an anti-peep method applicable to the anti-peep display device.
