Abstract:
A display device is provided. The display device comprises: a display panel; a collimation optical element located on a light emission side of the display panel and configured to modulate a first light emitted from the display panel into a collimated second light and emit the collimated second light; and a light modulation element located on a light emission side of the collimation optical element and configured to adjust an emission angle of the second light from the light modulation element. The first light emitted from the display panel is modulated into the collimated second light by the collimation optical element, the emission angle of the second light emitting from the light modulation element is adjusted by the light modulation element, such that the direction of the emission light of the display device is controllable.
