  • Electrowetting display pixels with quantum dots
    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.

  • Resist structure of an electrowetting element
    Patent number: 10054785
    Abstract: An electrowetting element comprises a first fluid and a second fluid immiscible with the first fluid. A first support plate comprises a first substrate; an electrode; and a layer in contact with at least one of the first fluid or the second fluid. A second support plate comprises a second substrate. One of the first support plate or the second support plate comprises a resist structure protruding in a direction towards the other one of the first support plate or the second support plate. The resist structure comprises a polymer nanocomposite material.

  • ELECTROWETTING DISPLAY DEVICE
    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.
