Patent ID: 8013506

Claim:
A method of adjusting an emission spectrum of a fluorescent layer in a fluorescent display that absorbs an excitation light at a single wavelength and emits visible light, the method comprising: generating a first mixture by combining one or more first non-phosphor organic compounds with a first binder material, wherein the first mixture substantially transmits the excitation light and substantially absorbs a portion of a respective emission spectrum of a first phosphor material; combining the first mixture with the first phosphor material to obtain a second mixture; generating a third mixture by combining one or more second non-phosphor organic compounds with a second binder material, wherein the third mixture substantially transmits the excitation light and substantially absorbs a portion of a respective emission spectrum of a second phosphor material; combining the third mixture with the second phosphor material to obtain a fourth mixture, wherein the fourth mixture and the second mixture have respective emission spectra that are different from each other; and applying the second mixture and the fourth mixture respectively on a substrate to form at least two adjacent fluorescent stripes on the substrate, wherein the at least two adjacent fluorescent stripes are configured to form two different colored sub-pixels of a same pixel when irradiated by the excitation light.
