Abstract

Provided are a display device, a backlight source, and an automobile. The display device includes a view angle control panel; in a sharing mode phase, a same voltage is provided for the first electrode and the second electrode; in a privacy mode phase, a first voltage is provided for the first electrode, and an alternating voltage signal is provided for the second electrode, where a high voltage of the alternating voltage signal is greater than the first voltage, and a low voltage of the alternating voltage signal is less than the first voltage; in a transition phase, the first voltage is provided for the first electrode, and a voltage signal with gradually changing duty cycles is provided for the second electrode; where the transition phase is located between the sharing mode phase and the privacy mode phase.
