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: A pixel structure includes a light emitting diode chip and a light blocking structure. The light emitting diode chip includes a P-type semiconductor layer, an active layer, an N-type semiconductor layer, a first electrode, and K second electrodes. The active layer is located on the P-type semiconductor layer. The N-type semiconductor layer is located on the active layer. The N-type semiconductor layer has a first top surface that is distant from the active layer. The first electrode is electrically connected to the P-type semiconductor layer. The light blocking structure is located in the light emitting diode chip and defines K sub-pixel regions. The active layer and the N-type semiconductor layer are divided into K sub-portions respectively corresponding to the K sub-pixel regions by the light blocking structure. The K sub-pixel regions share the P-type semiconductor layer.

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.
