Abstract
A display device includes a display panel and a light guide unit. The display panel includes a plurality of display units, and the plurality of display units generates a plurality of display light beams with different wavelengths, respectively. The light guide unit receives the display light beams from the plurality of display units. The light guide unit includes a plurality of input diffraction regions which change traveling directions of the display light beams, respectively, a light guide region that guides the display light beams with the changed traveling directions, and an output diffraction region which directs the guided display light beams to a predetermined direction.
Claims20
A display device comprising:
- a display panel including a plurality of display units, wherein the display units generates a plurality of display light beams with different wavelengths, respectively;
- and
- a light guide unit which receives the display light beams from the display units,
- wherein the light guide unit includes:
- a plurality of input diffraction regions which changes traveling directions of the display light beams, respectively;
- a light guide area which guides the display light beams with the changed traveling directions;
- and
- an output diffraction region which directs the guided display light beams to a predetermined direction.
A display device comprising:
- a first display panel which generates a first display light beam with a first wavelength;
- a second display panel which generates a second display light beam with a second wavelength;
- a third display panel which generates a third display light beam with a third wavelength;
- and
- a light guide unit which receives the first to third display light beams from the first to third display panels,
- wherein the light guide unit includes:
- first to third input diffraction regions which change traveling directions of the first to third display light beams, respectively;
- a light guide region which guides the first to third display light beams with the changed traveling directions;
- and
- an output diffraction region which directs the guided first to third display light beams to a predetermined direction.
