Abstract: An electrowetting element comprises a first fluid and a second fluid. A support plate surface has a first surface portion lying in a first plane, and a second surface portion lying in a second plane different from the first plane. The second surface portion comprises a first side, a second side, and a third side extending from the first side to the second side. The third side is located between the first surface portion and the second surface portion, with a first part of the third side non-perpendicular to the first side. A wall corresponds with a perimeter of the surface, the wall comprising: a first wall portion extending along the first side; and a second wall portion extending along the second side.

Abstract: Instead of using a clear or a semi-transparent notch within an electrowetting display, a colored notch that is the same color of the pixel region extends from one of the pixel walls toward an opposing pixel wall of the pixel region. The colored notches follow a non-flipped arrangement within each of the pixel regions. For example, each colored notch is adjacent to the same respective pixel wall for a pixel region. In other configurations, the colored notches follow a flipped arrangement within each of the pixel regions. For example, a colored notch of one pixel region and a colored notch of another pixel region are adjacent to the same pixel wall (on opposing sides). Instead of including a separate white sub pixel for each pixel, each pixel region is at least partially covered by a white color filter and a color filter that is the color of the pixel.

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, and a dielectric barrier layer on the electrode layer. The dielectric barrier layer comprises a first portion having a first dielectric constant and a second portion having a second dielectric constant that is substantially less than first dielectric constant. A hydrophobic layer is on the first portion and the second portion of the dielectric barrier layer.

Abstract: An electrowetting element comprising a first fluid and a second fluid immiscible with the first fluid. A first support plate comprises: a first support plate surface in contact with at least one of the first fluid or the second fluid, a substrate having a substrate surface, an electrode and a ridge. The ridge comprises a substantially parallel ridge surface substantially parallel to the substrate surface and a sloping ridge surface angled relative to the substantially parallel ridge surface. A wall is located at least partly on the substantially parallel ridge surface. The ridge is configured to reduce a flow of the first fluid along an inner surface of the wall.

Abstract: A method of controlling an electrowetting element. The method includes receiving first data corresponding with a first voltage with a first magnitude, generating the first voltage and applying the first voltage to the electrowetting element. Second data corresponding with a second voltage with a second magnitude is received. It is determined that the first magnitude is smaller than the second magnitude and, responsive thereto, a third magnitude of a third voltage is determined, the third magnitude larger than the first magnitude and smaller than the second magnitude. The third voltage is generated and applied to the electrowetting element instead of the second voltage, consecutively after the first voltage is applied.

Abstract: An electrowetting element includes a first fluid and a second fluid immiscible with the first fluid, as well as a surface, wherein display effects depend on an extent that the first and second fluids adjoin the surface, in dependence on applied voltage. Operation includes receiving data representing a first display effect for display; receiving data representing a subsequent display effect for display after display of the first display effect; comparing data representing the first display effect with data representing said subsequent display effect to determine a difference indicative of a change of the extent the second fluid adjoins the surface between display of the first display effect and display of the subsequent display effect; and depending on said difference, selectively outputting data for driving the electrowetting element to display a different display effect, instead of the subsequent display effect, consecutively after displaying the first display effect.

Abstract: A method for fabricating an electrowetting display may include depositing a first material layer on a support plate; placing a first mask on the first material layer, wherein the first mask covers first portions of the first material layer and does not cover second portions of the first photoresist layer; exposing second portions of the first material layer to electromagnetic radiation; depositing a second material layer on the first mask and the exposed second portions of the first material layer; placing a second mask on the second material layer; and etching to remove portions of the second material layer and the second portions of the first material layer. Portions of the first and second material layers that remain subsequent to the etching form spacers and a grid of pixel wall extensions.

Abstract: Subject matter disclosed herein relates to arrangements and techniques that provide for controlling motion of an electrowetting oil within an electrowetting display device. An electrowetting display device comprises a substrate, an electrode on the substrate, a dielectric layer on a first portion of the electrode. The electrode extends along the substrate one of either entirely from a first end of a pixel area to a second end of the pixel area, or from the first end of the pixel area to the second end of the pixel area such that a portion of the substrate is an electrode free portion to thereby define a notch. A first fluid is disposed on a hydrophobic layer and a second fluid is disposed on the first fluid, the second fluid being immiscible with the first fluid. A dielectric constant of the dielectric layer is greater than a dielectric constant of the first fluid.

The electrowetting element includes at least one reconfiguration reducer for reducing a reconfiguration of the first and second fluids from the first configuration to a second configuration. The second configuration has the first fluid adjoining the second area and the second fluid adjoining the first area, there being a tendency for said reconfiguration to occur when maintaining said applied voltage.
