Abstract
A display module and a method for driving the same, a display apparatus, and a vehicle are provided. The display module includes a backlight component, and a display component and a light-adjusting component that are 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 and a light regulating structure. The light-adjusting component includes first and second electrodes, and a first liquid crystal. The display module has a sharing mode and an anti-peeping mode. In the sharing mode, the first electrode and the second electrode are not energized, and the first liquid crystal is in a wide viewing angle state. In the anti-peeping mode, the first electrode and the second electrode drive the first liquid crystal to be in a narrow viewing angle state.
