Patent number: 7670450Abstract: A thermal transfer donor element is provided which can include a support, light-to-heat conversion layer, interlayer, and transfer layer. When the donor element is brought into contact with a receptor and imagewise irradiated, an image is obtained which is free from contamination by the light-to-heat conversion layer. In order to enhance the lifetimes of the transferred material, thermal treatments such as annealing are applied to the receptor before transfer, to the transfer layer after transfer, or a combination of them. The construction and process of the donor element is useful in making colored images including applications such as color proofs, color filter elements, and organic light emitting diode displays and devices.Type: GrantFiled: July 31, 2006Date of Patent: March 2, 2010Assignee: 3M Innovative Properties CompanyInventors: Sergey A. Lamansky, Erika Bellmann, Ha T. Le, John S. Staral, John P. Baetzold

Publication number: 20020158574Abstract: The present invention provides electronic displays and lamps that include a plurality of organic electroluminescent devices that emit polarized light. Displays can be made that include devices that emit the same or nearly the same polarization of light of different colors. For example, a full color pixilated display can be made that emits polarized light. Polarizing filters can be combined with such a display to reduce glare or increase display contrast without significantly reducing the intensity of the emitted light. Displays can also be made that include devices that emit different polarizations of light of the same or different colors. Tunable color of single color polarized light emitting lamps and backlights can also be made.Type: ApplicationFiled: April 27, 2001Publication date: October 31, 2002Applicant: 3M Innovative Properties CompanyInventors: Martin B.
