Abstract
A method of making an OLED device comprises the steps of: providing a donor element having transferable organic material in transfer relationship with an OLED substrate; forming a substantially uniform linear laser light beam; providing a spatial light modulator responsive to the linear laser light beam and adapted to form multichannel linear laser light beams; individually modulating selected channels to form one or more laser light beam segments wherein each segment can include one or more laser light beam channels and further wherein the laser light beam segment(s) have substantially square intensity profiles in a first direction and a substantially Gaussian intensity profile in a second direction perpendicular to the first direction and are directed onto the donor element; and the donor element producing heat in response to the light from the modulated segments so as to heat transfer organic material onto selected areas of the substrate.
