Abstract: Subject matter disclosed herein relates to improving a contact diameter of an adhesive/sealing material on surfaces of substrates by altering rheological properties of the adhesive/sealing material. An electrowetting display device comprises a first substrate and a second substrate, a first fluid and a second fluid disposed between the first substrate and the second substrate, wherein the first fluid is immiscible with the second fluid. An adhesive/sealing material comprising UV curable epoxy glue is in contact with the second fluid and couples the second substrate to the first substrate. The adhesive/sealing material further comprises silica particles in a range of 1-6% mass fraction of silica that alter rheological properties of the UV curable epoxy glue.

Abstract: Subject matter disclosed herein relates to arrangements and techniques that provide for improving contact between spacers of a first substrate of an electrowetting display device and pixel walls of a second substrate of the electrowetting display device by providing an adhesive between the spacers and the pixel walls. An electrowetting display device comprises a first substrate including a plurality of pixel walls and a second substrate including a plurality of spacers. A first fluid is disposed between the first substrate and the second substrate within the pixel walls. A second fluid is disposed on the first fluid, wherein the first fluid is immiscible with the second fluid. An adhesive couples the spacers to the pixel walls.

Abstract: A meltable ink which is solid at room temperature, which ink is suitable for use in an indirect printing process, in which printing process the ink is transferred, by the use of an inkjet printhead, to a transfer element, whereafter the ink is transferred to a receiving material under pressure from the transfer element, the ink having a composition such that it is pressure-transferable at a temperature between a bottom temperature limit and a top temperature limit, wherein the ink has a deformation energy of less than 20×105 Pa.s at a temperature equal to said top temperature limit.

Abstract: A method of printing a receiving material with hot melt ink using an intermediate element having a surface containing an elastomer with a surface tension in which the polar part thereof is less than or equal to 20 mN/m, wherein the receiving material is brought into contact with the intermediate element in such manner that the ink transfers from the intermediate element to the receiving material, and wherein the elastomer has a hardness of less than 80 Shore A, a thermal conductivity coefficient greater than 0.15 W/mK, and in absorption of less than 10%, and a tan? of less than 0.3.
