Abstract
A display apparatus and a display method are provided. The display apparatus includes a display panel, a display film assembly, a privacy film assembly, and a light source. The display film assembly includes a first light guide plate and an optical film. The optical privacy film assembly includes a second light guide plate and a privacy film. The privacy film is configured to adjust divergent lights exiting the second light guide plate into privacy lights at a preset angle. The light source is configured to emit incident lights to be selectively irradiated to the first light guide plate or the second light guide plate, so that the display apparatus is able to switch between a normal display mode and a privacy display mode.
