  • Patent number: 10444489
    Abstract: 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.

  • Patent number: 10108004
    Abstract: 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.

  • Patent number: 9581804
    Abstract: 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.

  • Publication number: 20160091709
    Abstract: An electrowetting display device includes a picture element. There is a surface for receiving incident radiation for entering picture element. A first fluid and a second fluid immiscible with the first fluid are usable to provide a display effect. At least one of the first fluid or the second fluid are susceptible to deterioration by exposure to radiation of at least one predetermined wavelength. A support plate is located between the surface and at least one of the first or second fluids. The support plate includes a layer including a radiation filter configured to filter radiation of the at least one predetermined wavelength.
