Electrowetting element including a compound comprising a plurality of colorant moieties and a linker. The plurality of colorant moieties includes a first colorant moiety having a first net dipole and a second colorant moiety having a second net dipole. The plurality of colorant moieties are linked by and disposed around the linker so that the first net dipole and the second net dipole at least partially cancel each other.

Electrowetting element

Electrowetting apparatus including at least one compound selected from the group consisting of: wherein each of R, R, Rand Ris independently an alkyl group. In examples a fluid includes a dye compound selected from: 

Carrier fluid compounds and dye compounds for electrowetting apparatus

An electrowetting display comprises a support plate on which individual electrowetting pixels separated from one another by pixel walls are formed. The individual electrowetting pixels include an electrode layer on the support plate, a dielectric barrier layer on the electrode layer, a hydrophobic layer on the dielectric barrier layer, and quantum dots between the hydrophobic layer and the electrode layer. The quantum dots may utilize blue or white light illuminating the pixels to emit longer-wavelength colors such as red and green. Such a feature may enhance or replace functionality of color filters.

Dye compounds for an electrowetting element

A method of manufacturing an electrowetting device includes dispensing a first liquid on a surface of a support plate and dispensing a second liquid to adjoin the first liquid. The first liquid is a solution. A first portion of the first liquid transfers into the second liquid to form a first layer of liquid and a second layer of liquid substantially immiscible with the first layer. The first layer comprises a second portion of the first liquid and the second layer comprises the second liquid and the first portion.

Method of preparing a compound

An electrowetting display device has first and second fluids which are immiscible with each other and a first and a second support plate, a surface of the second support plate being located for being adjoined by the second fluid. An electrode which contacts the second fluid forms part of a protrusion and is separated from the surface of the second support plate.

Electrode configurations for an electrowetting display device

A display apparatus includes an electrowetting display device with a first support plate, a second support plate and first and second fluids immiscible with each other in a space between the support plates. The first support plate has a display region comprising multiple display areas, each display area being associated with an electrode, the coverage of the first fluid over the display areas being independently controllable.
