| 20100271844 | LIGHT-GUIDING STRUCTURE WITH PHOSPHOR MATERIAL LAYERS - A light-guiding structure with phosphor material layers includes a light-guiding unit, a light-emitting unit and a phosphor unit. The light-emitting unit is disposed beside an outer lateral side of the light-guiding unit. The phosphor unit is connected with the light-guiding unit and is disposed between the light-guiding unit and the light-emitting unit. In addition, the phosphor unit is formed or pasted on the lateral side of the light-guiding unit, and the light-emitting unit has a PCB substrate and a plurality of light-emitting elements electrically disposed on the PCB substrate and facing the light-guiding unit. Hence, light beams generated by the light-emitting elements of the light-emitting unit pass through the phosphor unit to form another light beams, and the light beams are guided into the light-guiding unit. Finally, the light beams are projected out from a light-exiting face of the light-guiding unit. | 10-28-2010 |
| 20110110117 | Optical member and backlight using the same - There is provided a light diffusive plate and a light guide plate, in which the generation of deflection, a cause of defective imaging, can be prevented. | 05-12-2011 |
| 20110141769 | DISPLAY DEVICE - Provided is a display device. The display device includes a circuit substrate, a light source electrically connected to the circuit substrate, the light source being disposed under the circuit substrate, and a light conversion member disposed on a light emitting surface of the light source and a side of the circuit substrate, the light conversion member converting a wavelength of light emitted from the light source. Here, the light conversion member is disposed also on a side surface of the circuit substrate and converts a wavelength of light emitted from the light source. Since the light conversion member is disposed on the side surface of the circuit substrate, the light conversion member may be aligned with the light source without interfering with the circuit substrate. Thus, the display device may effectively convert the wavelength of the light emitted from the light source to realize improved brightness and color impression. | 06-16-2011 |
