Reporters obtained the following quote from the background information supplied by the inventors: "The invention relates to a light emitting device, especially to a wafer-type light emitting device having a precisely coated wavelength-converting layer.
"In a conventional light emitted diode (LED) configuration, it is typical that a fluorescent layer is coated on the LED to convert the wavelengths of emitted lights. As a result, the fluorescent layer is also called a wavelength-converting layer. However, since the amount of the fluorescent layer that is coated is difficult to control precisely, the thickness of the fluorescent layer often becomes too thin or too thick, and hence the production of LEDs will have a lower yield and a higher cost. Consequently, a light emitting device having a precisely coated wavelength-converting layer is needed so as to improve the yield and to lower the production cost."
In addition to obtaining background information on this patent, VerticalNews editors also obtained the inventors' summary information for this patent: "The invention relates to a wafer-type light emitting device having a substrate, one or more light emitting semiconductors formed on the substrate, one or more frames provided over the one or more light emitting semiconductors, and one or more wavelength-converting layers applied on the one or more light emitting semiconductors and confined by the one or more frames, wherein the wafer-type light emitting device is diced into a plurality of separate, individual light emitting units.
"Additional advantages and other aspects of the invention will be readily apparent from the following detailed description setting forth the principles of the invention with reference to the accompanied drawings."
