Abstract
An in-situ vacuum method for fabricating, at least in part, an OLED device that is moisture- or oxygen-sensitive, such method including providing into a vacuum coater a receiver element which will form part of the OLED device; providing into said vacuum coater a donor support element and coating such donor support element to produce a donor element with one or more layers required to produce all or part of the OLED device; positioning the coated side of the donor element in material transferring relinquish to the receiver element to be coated; and applying radiation to the d nor element to selectively transfer in vacuum one or more layers from the donor element to the receiver element.
Claims14
An in-situ vacuum method for fabricating, at least in part, an OLED device that is moisture- or oxygen-sensitive, such method comprising the steps of:
- a) providing into a vacuum coater a receiver element which will form part of the OLED device;
- b) providing into said vacuum coater a donor support element and coating such donor support element to produce a donor element with one or more layers required to produce all or part of the OLED device;
- c) positioning the coated side of the donor element in material transferring relationship to the receiver element to be coated within said vacuum coater;
- and
- d) applying radiation to the donor element to selectively transfer in vacuum one or more layers from the donor element to the receiver element.
An in-situ vacuum method useful in fabricating a full-color display formed of a number of OLED devices, such display being moisture- or oxygen-sensitive, such method comprising the steps of:
- a) providing into a vacuum coater a receiver element which will form part of the display;
- b) providing into said vacuum coater a plurality of donor support elements and coating such donor support elements with materials and wherein each of the donor support elements has at least one different material for providing a different output color from a corresponding OLED device;
- c) sequentially positioning the coated side of each of the donor elements in material transferring relationship to the receiver element to be coated;
- and
- d) sequentially applying radiation to the positioned donor elements to selectively transfer in vacuum one or more layers from each of the donor elements to corresponding OLED devices formed in the receiver element.
