Abstract: A light-enhancement device includes a wavelength conversion member and a wavelength controlling element. The wavelength conversion member includes a light-transmissive substrate and wavelength conversion material which is disposed within the light-transmissive substrate for converting a portion of light with a first wavelength into another light with a second wavelength. The wavelength controlling element is disposed on a surface of the light-transmissive substrate for reflecting another portion of the light with the first wavelength into the light-transmissive substrate and enabling the portion of the light with the second wavelength to pass through the wavelength controlling element. A roughness of the surface of the light-transmissive substrate facing towards the wavelength controlling element is configured to be 0-1 μm.

Abstract: A display device includes a substrate, a plurality of white light-emitting units, and a color filter layer. The white light-emitting units are arranged on the substrate at intervals, and the white light-emitting units are chip scale package (CSP). The color filter layer is above the white light-emitting units. Each of the white light-emitting units includes a light-emitting diode chip and a wavelength conversion film. The wavelength conversion film directly covers a top surface and side surfaces of the light-emitting diode chip, and the wavelength conversion film converts light emitted by the light-emitting diode chip into white light.

Abstract: The present invention provides a method for fabricating a fluoride phosphor. A first solution is formed by dissolving potassium fluoride (KF) and either K2MnF6 or KMnO4 in a hydrofluoric acid solution. A second solution is formed by mixing a surfactant and a silane. The first solution and the second solution are mixed to form a precipitate. The precipitate is collected after the first solution and the second solution are mixed. The present invention also provides a fluoride phosphor represented by the following formula: K2[SiF6]:Mn4+. The fluoride phosphor has a particle size in a range of about 1 μm to about 10 μm.
