摘要： Embodiments of a display device are described. A display device includes a backlight unit having a light source and a liquid crystal display (LCD) module. The light source is configured to emit a primary light having a first peak wavelength. The LCD module includes a first sub-pixel having a phosphor film and a second sub-pixel having a non-phosphor film. The phosphor film is configured to receive a first portion of the primary light and to convert the first portion of the primary light to emit a secondary light having a second peak wavelength that is different from the first peak wavelength. The non-phosphor film is configured to receive a second portion of the primary light and to optically modify the second portion of the primary light to emit an optically modified primary light having a third peak wavelength that is different from the first and second peak wavelengths.

摘要： Embodiments of a display device including barrier layer coated quantum dots and a method of making the barrier layer coated quantum dots are described. Each of the barrier layer coated quantum dots includes a core-shell structure and a hydrophobic barrier layer disposed on the core-shell structure. The hydrophobic barrier layer is configured to provide a distance between the core-shell structure of one of the quantum dots with the core-shell structures of other quantum dots that are in substantial contact with the one of the quantum dots. The method for making the barrier layer coated quantum dots includes forming reverse micro-micelles using surfactants and incorporating quantum dots into the reverse micro-micelles. The method further includes individually coating the incorporated quantum dots with a barrier layer and isolating the barrier layer coated quantum dots with the surfactants of the reverse micro-micelles disposed on the barrier layer.
