| description | The invention provides a side-in type backlight module, a display device, and a method for controlling the display device to realize real-time switching of normal display and anti-peep display. The side-in type backlight module includes a light guide plate and a light source; the orthographic projection of the emitting light emitted by the light source on the backlight surface of the light guide plate is vertical to a first light-emitting surface of the light source, and the emitting light inclines toward the direction close to the backlight surface of the light guide plate; multiple screen dots are embedded on the backlight surface of the light guide plate; each screen dot includes a first reflecting part; the first reflecting parts have first surfaces facing to the light source; the first surfaces are constructed into cambered surfaces raising toward the direction away from the light source; and the tangents of the cambered surfaces to the closest dots of second light-emitting surfaces of the light guide pl |
