Abstract: A light source includes a substrate and a plurality of light emitting devices disposed on the substrate. Each of the light emitting devices is configured to generate a first light. A plurality of quantum-dot devices are respectively disposed on the light emitting devices. The quantum-dot devices are configured to convert the first light to a second light. The quantum-dot devices are configured to be attached to and detached from the light emitting devices, respectively.

Abstract: A backlight unit includes a light source which generates a first light; a quantum dots member which is spaced apart from the light source by a first distance and converts the first light into a second light; a guide member which lengthwise extends in a first direction and fixes positions of the light source and the quantum dots member; and an optical member which reflects the second light. The guide member guides the first light from the light source to the quantum dots member and guides the second light from the quantum dots member to the optical member.

Abstract: A light source unit includes a light source configured to emit a light, a first case including a first groove configured to receive the light source therein, a first sealing member disposed in the first groove and covering the light source, a second case disposed on the first case and including a first opening portion overlapping with the first groove, and a quantum dot member disposed between the first case and the second case and including a light conversion area configured to convert the light to a white light and a defect area surrounding the light conversion area. The first opening portion is disposed through the second case, a portion of the light conversion area overlaps with the first opening portion and the first groove, and the light source unit is configured such that the white light exits therefrom through the first opening portion.

Abstract: A light generation member includes a light source which includes light source units which generate a first light, a light conversion member which converts the first light to a second light, and a light diffusion member which is elongated in a first direction, in which is defined first grooves respectively corresponding to the light source units, the light diffusion member diffusing the first light generated by the light source unites and providing the diffused first light to the light conversion member. The light diffusion member is between the light conversion member and the light source in a second direction crossing the first direction, and the first grooves defined in the light diffusion member are each elongated in a third direction substantially perpendicular to the first and second directions.

Abstract: A backlight unit includes a light source unit having a light source configured to emit a first light, a quantum dot sheet configured to emit a second light having a different color from the first light, a light guide plate configured to guide a light exiting from the light source unit or the quantum dot sheet, and an optical member including a prism sheet and configured to control the light exiting from the light guide plate. The quantum dot sheet includes a polymer resin and a plurality of first and second quantum dots, which are dispersed in the polymer resin. The second light is a white light obtained by mixing a red light, green light, and a blue light, and the second light has a concordance rate with an Adobe RGB color space which is no less than by about 99.9%.
