Abstract: A dye for a fluid of an electrowetting element, the dye having a general formula selected from the group consisting of: (Formula I, II and III) wherein Q has the general formula: -HetlRl or -HetlRlR2; V has the general formula: -Het2R3 or -Het2R3R4; Hetl and Het2 are heteroatoms; Rl and R3 are H; R2 and R4 are any functional group; T and U are any functional group; W, X, Y and Z are H or an alkyl group; and F, G, L and M are H or an alkyl group, and with the proviso that the dye does not have the general formula: (IV). The present invention further relates to a fluid comprising a dye of the present invention, an electrowetting element and an optical display device comprising the fluid, and a use of the dye to reduce photo-bleaching.

Abstract: The present invention relates to reducing backflow in an electrowetting element for modifying a radiation beam characteristic. The electrowetting element comprises a first and a second fluid which are immiscible with each other and are switchable between a first configuration and a second configuration by application of a voltage across at least one of the first and second fluids. There is a tendency for backflow of the second fluid from the first configuration to the second configuration when the second fluid is switched to be provided in the first configuration. The electrowetting element comprises a backflow reducer arranged for reducing the backflow of the second fluid from the first configuration to the second configuration when the second fluid is switched to be provided in the first configuration.

Abstract: Dispensing method and device for dispensing A method of providing a laye r of a first fluid on an area (2) of a surface by means of a dispenser (3) having an opening (8). The method comprises the step of providing a layer of a second fluid (7) on the surface, the second fluid being immiscible with the first fluid. It also includes the step of arranging the opening of the dispenser in the second fluid above the area and the step of dispensing the first fluid (6) through the opening assisted by a third fluid (9 ) for settling on the first area, the third fluid being immiscible with the first fluid.
