Abstract: A display module, a display apparatus, and a vehicle are provided. The display module includes a backlight component, and a display component located at a side of the backlight component facing toward a light-emitting direction of the display module. The backlight component includes a first light guide structure, a light regulating structure, and a polymer liquid crystal film. The first polarizer is located at a side of the polymer liquid crystal film facing away from the backlight component. The polymer liquid crystal film is located at a side of the light regulating structure facing away from the first light guide plate and includes a polymer liquid crystal layer, and an electrode layer located at each of at least one side of the polymer liquid crystal layer. The display module has a sharing mode where the electrode layer is not energized and an anti-peeping mode where the electrode layer is energized.

Abstract: The present disclosure provides a display panel, display device and display method. Under a wide viewing angle display mode, a first signal is applied to a first electrode and a second electrode, and a long axis of liquid crystal molecules and a long axis of dye molecules are perpendicular to a plane of a first substrate. A relatively large included angle is formed between a polarization direction of emergent light of a first display device and the long axis of the dye molecules. A second signal is applied to the first electrode and the second electrode under a narrow viewing angle display mode, and a long axis of liquid crystal molecules and a long axis of dye molecules form an included angle of 30 to 60 degrees together with the plane of the first substrate.
