摘要： A directional backlight unit and an image display apparatus including the directional backlight unit are provided. The directional backlight unit includes at least one light source and a light guide plate that guides light emitted by the light source. An interval between grating patterns formed on the light guide plate satisfies at least one condition of a first range and a second range in order to minimize a spreading of light caused by the grating patterns.

摘要： Provided are a lighting system, a backlight unit and a 3D image display apparatus including the backlight unit. The backlight unit includes: a lighting system configured to selectively output collimated light and diverging light, a diffraction device, and a light guide plate configured to guide the collimated light and the diverging light from the lighting system to the diffraction device. An exit direction of the collimated light from the diffraction device depends on at least one of an angle of incidence of the collimated light and the wavelength of the collimated light.

摘要： A see-through display device includes an optical coupler that couples first light input from a first direction and second light input from a second direction that is different from the first direction, the optical coupler transferring coupled light including the first light and the second light to an observer, and a shading member disposed in front of the optical coupler, the shading member transferring the second light to the optical coupler by reducing a light amount of the second light. The see-through display device limits a reflection phenomenon occurring between the optical coupler and the shading member.
