Title: SIMULTANEOUS DOCTOR BLADING OF DIFFERENT COLORED LIGHT EMITTING COMPONENTS
Abstract:
Methods for simultaneously forming two or more different colored material layers on a substrate. include performing surface energy patterning (SEP) to define a first, hydrophobic region and a second, hydrophilic region on the substrate, applying first and second materials on the second region, wherein the first material comprises a material having a first color, and wherein the second material comprises a material having a second color, and doctor blade coating the first and second materials simultaneously to form first and second material layers on the substrate. The methods are particularly useful for making multi-color light emitting and detecting components such as LEDs and OPDs.
