摘要:
A method for forming a color organic light-emitting device including depositing a first electrode over a substrate; depositing a first emissive layer over the first electrode for producing a first colored light in response to hole-electron recombination; and selectively patternwise depositing a hole-blocking layer over the first emissive layer. The method also includes depositing a second emissive layer over the hole-blocking layer which in response to hole-electron recombination emits colored light different from the colored light emitted from the first emissive layer; depositing a second electrode over the second emissive layer; and whereby the patternwise deposition of the hole-blocking layer has been selected to substantially shift hole-electron recombination from the second to the first emissive layers.
摘要:
An in-situ method for fabricating, at least in part, an OLED device that is moisture- or oxygen-sensitive, such method comprising the steps of: providing into a controlled atmosphere coater a receiver element which will form part of the OLED device; providing into the controlled atmosphere 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; controlling the atmosphere in the controlled atmosphere coater under controlled conditions; positioning the coated side of the donor element in material transferring relationship to the receiver element to be coated; and applying radiation to the donor element to selectively transfer one or more layers from the donor element to the receiver element.

A donor element adapted for use in making an OLED device including a donor support element; a light-absorbing layer disposed over the donor support element, which in response to light, produces heat; a host material layer disposed over the light-absorbing layer; and a dopant layer disposed over the host material layer such that when the donor element is placed in a transfer relationship with the OLED device and when light is absorbed by the light-absorbing layer, heat is produced that causes the vaporization transfer of host materials and dopant materials from the light-absorbing layer to cause at least partial mixing in the OLED device.
摘要:
A method for making an organic electroluminescent display device having an array of pixels disposed on a display substrate includes providing a donor element and a display substrate that are heated to a desired temperature. Radiation-induced thermal transfer is then used to transfer organic material from the donor element to the display substrate.
