20130256603 | LIQUID COMPOSITION FOR DEPOSITION OF ORGANIC ELECTROACTIVE MATERIALS - Compositions are provided for improved liquid deposition of electroactive material onto low surface energy layers. The liquid composition includes at least one organic electroactive material in a liquid medium. The liquid medium includes (a) at least 20% by volume, based on the total volume of the liquid medium, of a first solvent and (b) at least 1% by volume, based on the total volume of the liquid medium, of a liquid organic additive. The liquid medium pins on the underlying layer as determined by a dynamic receding contact angle test. The first solvent retracts on the underlying layer as determined by the dynamic receding contact angle test. | 10-03-2013 |
20120077043 | TRANSPARENT COMPOSITE CONDUCTORS HAVING HIGH WORK FUNCTION - There is provided a transparent composite conductor. The composite conductor has a first layer that includes a transparent conductive material and a second layer that includes a fluorinated acid polymer. | 03-29-2012 |
20110222222 | ELECTRONIC DEVICES AND PROCESSES FOR FORMING THE SAME - An electronic device includes an array. In one embodiment, a process for forming an electronic device includes the array, which includes electronic components, can include printing one or more layers as a series of segments onto a workpiece. In one embodiment, a process includes printing a layer onto the workpiece and at least one exposed portion of the chuck. In still another embodiment, a printing head is greater than 0.5 mm from the workpiece. In a further embodiment, “hybrid” printing can be used to help form a thicker layer having a relatively thinner width. In a further embodiment, processes can be used to reduce the likelihood of a stitching defect, nonuniformity of a layer across an array, or a combination thereof. A printing apparatus can be modified to achieve more flexibility in liquid compositions, temperatures or other conditions used in printing a layer. | 09-15-2011 |
20110183268 | PROCESS FOR MAKING CONTAINED LAYERS AND DEVICES MADE WITH SAME - There is provided a process for forming a contained second layer over a first layer, including the steps:

20110163271 | ELECTRICALLY CONDUCTIVE POLYMER COMPOSITIONS - The present invention relates to electrically conductive polymer compositions, and their use in organic electronic devices. The electrically conductive polymer compositions include (i) an intrinsically conductive polymer having at least one monomer unit which is a pyridine-fused heteroaromatic and (ii) a fluorinated acid polymer. | 07-07-2011 |
20100291721 | PROCESSES FOR FORMING ELECTRONIC DEVICES INCLUDING SPACED-APART RADIATION REGIONS - Processes for forming an electronic device include forming a first radiation region, a second radiation region spaced apart from the first radiation region, and an insulating region. The insulating region can have a first side and a second side opposite the first side. The first radiation region can lie immediately adjacent to the first side, and the second radiation region can lie immediately adjacent to the second side. Within the insulating region, no other radiation region may lie between the first and second radiation regions, and the insulating region can include an insulating layer that includes a plurality of openings. A process for forming the electronic device can include patterning an insulating layer. | 11-18-2010 |
