Abstract: The invention discloses a backlight apparatus including a wavelength-converting device and a light source. The wavelength-converting device includes a transparent upper barrier film, a transparent lower barrier film, a spacer layer, a filling material and a plurality of quantum dots. The spacer layer is bonded between the transparent upper barrier film and the transparent lower barrier film, and has a plurality of hollowed regions. The filling material covers the plurality of hollowed regions. The plurality of quantum dots are uniformly distributed in the filling material covering each hollowed region. The light source includes a circuit board and a plurality of semiconductor light-emitting device. The circuit board is disposed beneath the transparent lower barrier film. Each hollowed region corresponds to at least one semiconductor light-emitting device. Each semiconductor light-emitting device is electrically bonded on the circuit board, and locates beneath the corresponding hollowed region.

Abstract: The invention discloses an indicating/alarming apparatus which includes an optically transparent polymer plate, a light-shielding layer, a flexible circuit board, a plurality of light-emitting devices and a light-reflecting layer. The light-shielding layer is formed to overlay an upper surface of the optically transparent polymer plate. The plurality of light-emitting devices are soldered on the flexible circuit board. The flexible circuit board is mounted on a lower surface of the optically transparent polymer plate such that the plurality of light-emitting devices are disposed within an opening formed on the lower surface of the optically transparent polymer plate. Each light-emitting device emits a light entering from a light incident face of the opening into the optically transparent polymer plate which guides, due to total reflection, the light to exit from a top side surface, a bottom side surface, a first edge surface, a second edge surface and sites on surfaces whose total reflection is broken.

Abstract: An optical module has a support, an optical film and a buffer. The optical film has a protrusion on one edge thereof. The buffer is disposed on the support and has a corresponded notch to accommodate the protrusion.

Abstract: A reflector in a backlight module comprises a reflection layer and an electrical conduction layer. The conducting is installed on one side of a reflection layer, and is connected to the ground of the system. Thereby, when the reflector is applied to an edge-type or a direct-type backlight module, by grounding the electrical conduction layer, normal operations of devices in the backlight module will not be affected by electromagnetic interference (EMI) or electrostatic discharge (ESD).

Abstract: A backlight unit applied on a display device is disclosed. The backlight unit includes a base having a frame, an optical film, an adhesive and a shading tape. The frame has at least a recess, and the optical film has at least a flange for inserting in the recess of the frame. The shading tape locates on the frame, and the adhesive locates between the frame and the shading tape only. No adhesive exists between the optical film and the shading tape.
