Patent ID: 7645478

Claim:
A method of preparing a display, the method comprising: patterning a set of zinc oxide channel thin film transistor row and column drivers on a display substrate; patterning a set of zinc oxide channel pixel thin film transistors on the display substrate, the pixel thin film transistors being in electrical contact with the thin film transistor row and column drivers; and forming a set of organic light emitting diodes on the display substrate, each organic light emitting diode comprising a first electrode, a second electrode, and a light-emitting material positioned between the first electrode and the second electrode, wherein the forming of at least one organic light emitting diode comprises providing a first electrode in electrical contact with at least one pixel thin film transistor; preparing a first donor sheet comprising a first donor substrate and a first thermal transfer layer comprising a first light-emitting material; transferring the first thermal transfer layer from the first donor sheet, wherein the first thermal transfer layer is transferred adjacent to the first electrode; and depositing a second electrode, wherein the first thermal transfer layer is positioned between the first electrode and the second electrode.
