Abstract: A backlight module including a light guide plate, a light source, a diffuse reflector and a light-splitting film is provided. The light guide plate has a light incident surface, and a light-emitting surface and a bottom surface which are respectively connected to the light incident surface and opposite to each other. The light source is disposed on one side of the light incident surface of the light guide plate. The diffuse reflector is disposed on one side of the bottom surface of the light guide plate. The light-splitting film is disposed between the light guide plate and the diffuse reflector. The light-splitting film has a substrate and a plurality of first optical microstructures disposed on one side of the substrate. An extending direction of the first optical microstructures intersects with the light incident surface of the light guide plate. A display apparatus using the backlight module is also provided.

Abstract: A white light emitting diode component capable of emitting white light includes an LED chip capable of emitting luminescent light, a first phosphor for absorbing first luminescent light of the luminescent light and emitting first emission, and a second phosphor for absorbing second luminescent light of the luminescent light and emitting second emission. A blend of the luminescent light (except for the first and the second luminescent light) and the first and the second emissions forms the white light. The first phosphor has a chemical formula of (Ca1?x?yEuxMy)Se, where x is not equal to zero, y is between zero and one, and M is composed of at least one element selected from a group consisting of Be, Mg, Sr, Ba, and Zn.

Abstract: A method for manufacturing white light source includes the steps of providing an ultra-violet light as radiation source; and preparing two kinds of phosphors each receiving the ultra-violet light and emitting light of different wavelength. One phosphor is designated to emit light covering two wavelength regimes of three primitive colors, i.e., red light (585-640 nm), green light (500-570 nm) and blue light (430-490 nm), and another phosphor is designated to emit light covering remaining wavelength regime of the three primitive colors. The phosphors are mixed in predetermined ratio such that the lights of different wavelength are combined to provide a white light.
