Abstract: A display device and a manufacturing method thereof are provided. The display device includes a first liquid crystal panel for displaying a picture, a second liquid crystal panel for switching between a privacy mode and a sharing mode, and a back light assembly for emitting light; the second liquid crystal panel is disposed on a light-emitting side of the back light assembly; the first liquid crystal panel is disposed on a side of the second liquid crystal panel away from the back light assembly, and a spacer film is disposed between the first liquid crystal panel and the second liquid crystal panel, and is attached to the second liquid crystal panel.

Abstract: The present disclosure relates to a backlight module, a display device and a control method thereof. The display device includes a first edge, a second edge, and N display areas.

Abstract: A dual-die device, a display device and a driving method thereof are provided. The dual-die device includes: a first light emitting die for emitting light containing short-wave blue light; a second light emitting die for emitting light from which short-wave blue light is filtered out; and a control circuit. The control circuit is connected to the first light emitting die and the second light emitting die, and configured to control the first light emitting die or the second light emitting die to be turned on.

Abstract: Disclosed are a display module, a display device and a viewing-angle switching method. The display module includes a backlight module, a display panel, a lower polarizer sheet, a viewing-angle switching element and a transparent cover plate; the viewing-angle switching element and the transparent cover plate are arranged between the display panel and the lower polarizer sheet, and the transparent cover plate is arranged on a side of the viewing-angle switching element that is close to the lower polarizer sheet; the backlight module is configured to supply light that meets a preset condition, the viewing-angle switching element is configured to switch viewing-angle modes of the display module; the viewing-angle modes include; a first viewing-angle mode and a second viewing-angle mode; and a viewing-angle range of the first viewing-angle mode is smaller than a viewing angle range of the second viewing-angle mode.
