ABSTRACT:
A method of transferring organic material from a donor element onto a substrate of an OLED device, includes providing a linear laser light beam which is moved relative to the donor element and substrate and which has a predetermined number of laser modulatable channels, each of which when activated causes laser light to illuminate the donor element which heats to a sufficient level to vaporize organic material and transfer such material onto a substrate; and selecting the pattern of activated laser modulatable channels such that only a portion of the OLED device receives organic material during a single relative motion pass of the linear laser light beam to the donor element and substrate.
