Patent ID: 7098060

Claim:
A method for producing a full-color, subpixellated organic electroluminescent (EL) device comprising: a) providing a substrate, b) depositing an anode layer onto said substrate, c) establishing a plurality of discreet wells in sets of three on said substrate, wherein said discreet wells are formed by circumscribing walls to form said wells, wherein each well defines a subpixel and each set of three wells defines a pixel, d) depositing a buffer layer onto said anode layer in each of said wells, e) depositing an unpatterned EL host polymer layer selected to produce blue light in each of said wells, f) depositing a first patterned dopant layer selected to produce red light in a first well in at least one of said set of three wells without prior surface treatment of said walls of said well, g) depositing a second patterned dopant layer selected to produce green light in a second well in at least one of said set of three wells without prior surface treatment of said walls of said well, h) depositing a cathode layer, thereby producing a full-color, subpixellated electroluminescent device.
