Abstract:
A method of fabricating a multicolor display, said method comprising:depositing a dielectric layer over a transparent substrate; depositing a green phosphor layer over said dielectric layer; depositing an etch-stop, dielectric layer over said green phosphor layer; depositing a red phosphor layer over said etch-stop, dielectric layer; patterning via angle-dry etch to create a mesa-structure having first, second and third mesas, wherein each mesa has at least two angled side walls; etching to remove said red phosphor from said first mesa; etching to remove said green phosphor from said second mesa; depositing a transparent conductive coating over said two dimensional mesa structure to form contacts on said mesas; depositing an isolation dielectric over said mesa structure; etching windows in said isolation dielectric, wherein the placement of said windows corresponds to the position of the transparent conductive depositing a blue OLED structure over said isolation dielectric such that said blue OLED contacts said transparent conductive coating through said windows; depositing a reflective conductive coating over said blue OLED to form contacts on said blue OLED.
