A drop generator operable to selectively form a drop having a first size and a drop having a second size from liquid emitted through a nozzle associated with the drop generator. The drop having the first size and the drop having the second size travel along a drop trajectory with the first size being larger than the second size when compared to each other. Each of the drops has a drop velocity. A gas flow deflection system includes a gas flow that is directed at a deflection zone that comprises at least a portion of the drop trajectory. The gas flow in the deflection zone includes a velocity vector having a parallel velocity component and a perpendicular velocity component with the parallel velocity component and the perpendicular velocity component being defined relative to the drop trajectory.

A method of forming a liquid pattern according to liquid pattern data on a receiving medium using a liquid drop emitter that emits a continuous stream of liquid from a nozzle that is broken into drops of predetermined volumes by the application of drop forming energy pulse is disclosed comprising associating a pixel area of the receiving medium with a nozzle and a time interval during which a plurality of fluid drops ejected from the nozzle can impinge the pixel area of the receiving medium. The time interval is divided into a plurality of subintervals that are, in turn, grouped into a plurality of blocks. Each block is defined as a printing block or a non-printing block. A drop forming energy pulse is provided between each pair of consecutive blocks and between the subintervals of each printing block. No drop forming energy pulses are provided between the subintervals of the non-printing blocks. The so-formed energy pulse sequence is applied to the stream of liquid causing the formation of small print drops and large non-print drops. The liquid pattern is formed on the receiver of print drops comprised of liquid emitted during subintervals associated with printing blocks. The block configuration is designed to ensure that non-print drops have the proper volume. In an alternate set of embodiments, individual subintervals rather than blocks of subintervals are individually defined as print or non-print subintervals subject to a non-print drop rule that forces non-print drops to be formed of adequate volume for differentiation from print drops and a maximum drop rule that ensures that non-print drops are not too large to be reliably captured and guttered.

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.

Linear laser light beam for making OLEDS

A method of operating on a flexible donor sheet, before or after organic material has been transferred to such sheet, to form a rigid edge frame to facilitate its mounting, including cutting notches in each of the four corners of the sheet, and folding the four notched edge portions of the sheet and securing the folded portions to the main body of the sheet to form at least four rigid edges so as to provide a rigid edge frame which can be readily mounted in an OLED device manufacturing process.

A method of securing a flexible donor sheet, before or after organic material has been transferred to such sheet to facilitate its mounting, includes forming a plurality of spaced apart openings in the sheet adjacent to opposite edges of the sheet, and providing a rigid frame for receiving the sheet having a plurality of tabs, each one of the tabs corresponding to an opening in the sheet and arranged so that an edge portion of the sheet adjacent to the opening is placed under its corresponding tab.

Apparatus for permitting the laser transfer of organic material from a donor onto a substrate to form a layer of organic material on one or more OLED devices, wherein the donor includes a laser light-absorbing layer, and a layer with heat transferable organic material.

Laser transfer of organic material from a donor to form a layer in an OLED device

Apparatus for permitting the transfer of organic material from a donor onto a substrate to form a layer of organic material on one or more OLED devices, comprising a first fixture arranged to support the donor and substrate in a relationship relative to one another whereby there will be either a separation between portions of the substrate and the donor, or the substrate and donor will be in contact, and wherein organic material will be transferred onto portions of the substrate; a second fixture aligned with and engaging the first fixture to clamp the donor and substrate and forming a chamber relative to a non-transfer surface of the donor; means for supplying a fluid to the chamber to apply pressure to the non-transfer surface of the donor so as to ensure the position of the donor relative to the substrate; and the first fixture including a transparent portion located in relationship to the non-transfer surface of the donor to permit transmission of radiation through such transparent portion to the non-transfer surface of the donor so that heat will be produced and the organic material will transfer from the donor to the substrate.

Apparatus for transferring organic material from a donor web onto a substrate to form a layer of organic material on one or more OLED devices including a web of donor material; first and second fixtures and a structure for applying fluid to a chamber to containing the fixtures to apply pressure to the non-transfer surface of the donor web so as to ensure the position of the donor web relative to the substrate; the first fixture including a transparent portion located in relationship to the non-transfer surface of the donor web to permit transmission of radiation through such transparent portion to the non-transfer surface of the donor web so that heat will be produced and the organic material will transfer from the donor web to the substrate.

Sheet collation apparatus and method operate on a random array of seriatim sheets to effect ordered stack collation. An edge guide surface is located along a sheet support surface extending from a sheet ingress to egress. A plurality of conical rollers are configured and relatively overdriven to effect edge alignment and sheet end separations between the sheet ingress and egress.

An improved light-tight package for a roll (10) of a length (14) of web material such as photographic paper or film. The package includes an opaque leader (22) wound around the roll. Folded-over portions (48,50) of opaque tearable end disks (32,34) are held in place by tearable adhesive tape strips (44,46). The leader includes a portion adapted to initiate a tear in the tearable tape. Upon unrolling of the package by pulling the leader, the tape tears, and the end disks tear circumferentially, whereby the folded-over portions adhere to the leader when the leader separates from the roll.

A spool for holding photographic film, consisting of a core member provided with flanges between which flexible film may be wound and an elongated slot into which the end portion of a film strip may be entered and fastened. Adjacent the flanges are raised shoulders extending about the circumference of the core and above the core surface. The shoulders each gradually increase in thickness in the film-winding direction and terminate in a stepped portion corresponding to the thickness of the film. In a preferred embodiment, shoulder portions accommodate the edge portion of a full-width film, have an initial height above the surface level of said spool, and then rise gradually to an additional height approximately equal to the thickness of the film. When the full-width portion of the film is juxtaposed the spool flanges, said shoulders provide the film with a substantially level transition surface for each convolution of the full-width film, thereby avoiding imperfections on the spool-core surface.
