Method of making an OLED device

摘要

A method of making an OLED device includes forming a color filter array over one surface of a substrate; forming by an evaporation process an anode over the second surface of the substrate and a hole-transporting layer over the anode; moving one or more coated donor elements into a transfer position relative to the hole-transporting layer and transferring emissive material from the donor elements onto the hole-transporting layer to form a light-emitting layer which is capable of emitting white light; and coating by an evaporation process a cathode over the light-emitting layer.
