Abstract

The invention discloses a backlight module and a peep-proof display device, and relates to the technical field of display. The visual effect of the peep-proof display device can be improved without affecting the peep-proof effect of the peep-proof display device. The backlight module comprises a light guide plate, a lens, and a light source. The lens is disposed between the light source and the light guide plate. Light emitted by the light source goes into the light guide plate through the lens at the same incident angle. The light-out surface of the light guide plate is provided with a plurality of bumps, and the light-out surface of the light guide plate is a total reflection surface except the bump areas. The light-out surfaces of the bumps are parallel to the light-out surface of the light guide plate. Light going to the bumps is first reflected by the total reflection surface, and then goes out in a direction vertical to the light-out surfaces of the bumps after one-time total reflection. The backlight module provided by the invention is suitable for electronic display equipment in need of backlight.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and an anti-peeping display device. Background technique [0002] At present, when users conduct business activities or consult confidential information through electronic display products in public places, they need to ensure the security of information. Peeping film, the anti-peeping film reduces the viewing angle of the display device through the light-shielding strip on it, so that the user can only see the displayed content within the allowable range of the viewing angle. However, the shading strips on the anti-peeping film will affect the brightness of the liquid crystal panel and affect the visual effect of the anti-peeping display device. Contents of the invention [0003] The object of the present invention is to provide a backlight module and an anti-peeping display device, which are used to improve the visual effect of the anti-peeping display de...
