Abstract: A method of making an OLED device, including providing a substrate having a first electrode and a conductive bus line provided over the substrate and organic EL media provided over the first electrode and over the conductive bus line; forming a radiation absorbing structure associated with the conductive bus line; exposing the radiation absorbing structure to radiation to produce heat sufficient to ablate a portion of the organic EL media thereby forming an opening in the organic EL media; and forming a second electrode over the organic EL media, and through the opening in the organic EL media thereby forming an electrical connection between the second electrode to the conductive bus line.

Abstract: A method of forming a pattern of electrical conductors on a receiving substrate (110) comprises forming metal nanoparticles of a conductive material. A donor substrate (45) is formed. A layer of release material (75) is deposited on a first side of the donor substrate. The metal nanoparticles are deposited on the release material. The metal nanoparticulate layer are placed in contact with the receiving substrate. A pattern is written on a sandwich formed by the donor substrate and the receiving substrate, causing metal nanoparticles from the nanoparticulate layer (90) to anneal and transfer to the receiving substrate to form the pattern of electrical conductors on the receiving substrate.

Abstract: A donor element for transferring organic material to form an OLED device includes a transparent support, a first metallic layer responsive to radiation which passes through the transparent support to produce heat, a second metallic layer that is reactive to moisture or oxygen or both provided over the first metallic layer, and an organic layer having transferable organic material disposed over the second metallic layer which, in response to radiation absorbed by the first metallic layer, will cause the organic material to be transferred to an OLED device.

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.

Abstract: A method of transferring organic material from a donor element to a substrate includes providing a radiation source; and selecting the power of the radiation applied to the donor element by the radiation source to cause the transfer of organic material to the substrate wherein the time that one or more positions of the donor element receives radiation is greater than 1 millisecond.
