Patent number: 7892382Abstract: An electroluminescent device, and a method of making an electroluminescent device that includes one or more color conversion elements is disclosed. In one embodiment, the method includes forming an electroluminescent element on a substrate, where the electroluminescent element is capable of emitting light in a narrow band. The method further includes selectively thermally transferring a plurality of color conversion elements to the electroluminescent element. In another embodiment, the method includes forming an electroluminescent element on a substrate, where the electroluminescent element is capable of emitting UV light. The method further includes selectively thermally transferring a plurality of color conversion elements to the electroluminescent element.Type: GrantFiled: November 16, 2004Date of Patent: February 22, 2011Assignee: Samsung Mobile Display Co., Ltd.Inventors: Erika Bellmann, Vadim Savvateev, Martin B.

Patent number: 7759042Abstract: Laser induced thermal imaging (LITI) donor films, and methods of preparing them, having a substrate, a light-to-heat conversion layer, and a pattern-directing layer. The pattern-directing layer can include patterns of self-assembled monolayer regions, hydrophilic and hydrophobic regions, positively or negatively charged regions, or a series of raised or recessed features. It can also be used to generate charge patterns and magnetic patterns. The pattern-directing layer causes patterning of a transfer layer applied to it, resulting in a templated transfer layer. When imaged, the LITI donor film transfers at least a portion of the templated transfer layer to a permanent receptor while maintaining the pattern substantially intact in the transferred portion.Type: GrantFiled: September 11, 2009Date of Patent: July 20, 2010Assignee: 3M Innovative Properties CompanyInventors: Martin B. Wolk, John E. Potts, Yingbo Li, Khanh T. Huynh

Patent number: 7678526Abstract: Radiation curable thermal transfer elements including a substrate and a light-to-heat conversion layer overlaying the substrate, and processes to make the thermal transfer elements. The light-to-heat conversion layer is derived from a radiation curable material capable of being cured by exposure to radiation at a curing wavelength and an imaging radiation absorber material not substantially increasing radiation absorbance at the curing wavelength. The radiation curable transfer elements can be used in processes for making organic microelectronic devices.Type: GrantFiled: May 2, 2008Date of Patent: March 16, 2010Assignee: 3M Innovative Properties CompanyInventors: Robin E. Wright, Khanh T. Huynh, Leslie A. Kreilich, Lan H. Liu, Rachel K. Swanson, Richard L. Walter, Martin B Wolk, Stephen A. Johnson, William A. Tolbert

Publication number: 20100006211Abstract: Laser induced thermal embossing (LITE) films used to make microreplication tools, liners, and products such as laser induced thermal imaging (LITI) donor films. The LITE tools or liners have a microstructured surface selectively imposed upon them as determined by an area of imaging the LITE films against one or more microreplication tools. An orientation between the laser imaging lines and LITE films can be selected to produce various microreplication patterns on the tools. The LITE tools can be made having a structure on structure pattern including a microstructured pattern with a nanostructured surface. The LITE liners can be combined with other films to form products. The LITE films can also be coated with a transfer layer to form a LITE donor film with a structured transfer layer.Type: ApplicationFiled: August 19, 2009Publication date: January 14, 2010Inventors: Martin B Wolk, Mieczyslaw H. Mazurek, Khanh T. Huynh, John P. Baetzold, Yingbo Ll, Audrey A. Sherman, Wendi J. Winkler

Patent number: 7534543Abstract: A thermal transfer donor element is provided which includes a support, light-to-heat conversion layer, interlayer, and thermal transfer layer. When the donor element is brought into contact with a receptor and imagewise irradiated, a portion of the transfer layer is transferred to the receptor. The relative surface texture of the layers can be at least partially controlled, prior to imaging of the donor element, for desired effects in the resulting receptor device. 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 displays.Type: GrantFiled: August 2, 2005Date of Patent: May 19, 2009Assignee: 3M Innovative Properties CompanyInventors: Leslie A.
