The invention provides a display module, a display device and a peep-proof control method of the display device, which are applied to the field of display and are used for solving the problem of loss caused by peeping of the display device by people except a user. The display module comprises a backlight module used for emitting light and providing a backlight source. The dimming panel is arranged on the light emitting side of the backlight module and can be switched between a non-peep-proof state and a peep-proof state, and the peep-proof direction of the dimming panel is the first direction. And the display panel is used for displaying a picture to be displayed. The peep-proof film layer is arranged on the light emitting side of the backlight module and used for collimating light rays emitted to the peep-proof film layer, so that the scattering angle of the light rays is narrowed in the second direction. The second direction is perpendicular to the first direction. 本发明提供了一种显示模组、显示装置及显示装置的防窥控制方法，应用于显示领域，为解决显
