发明名称 OLED patterning method
摘要 A method of forming a patterned, light-emitting device that includes mechanically locating a first masking film over a substrate; forming first openings in first locations in the masking film; and depositing first light-emissive materials over the substrate through the first openings in the first masking film. Subsequent steps include mechanically removing the first masking film; mechanically locating a second masking film over the substrate in a position that prevents particulate contamination in the first locations; and forming second openings in the second masking film. The second openings are in different locations over the substrate than the first openings. The first locations are protected from particulate contamination resulting from the formation of the second openings. Additional steps include depositing second light-emissive materials over the substrate through the second openings in the second masking film; and mechanically removing the second masking film.
