Abstract: An electrowetting element comprising: a first fluid and a second fluid immiscible with the first fluid; and a surface. The first and second fluids are switchable to a first configuration by application of a voltage, the first fluid adjoining a first area of the surface and the second fluid adjoining a second area of the surface in the first configuration. 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.

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.

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: A system and method for a display device are presented. The display device includes a first support plate. A wall is over the first support plate. The wall is associated with an electrowetting pixel. The wall is configured to allow for the propagation of light having a wavelength within a first range of wavelengths and prevents propagation of light having a second wavelength in a second range of wavelengths. A color filter is positioned over the electrowetting pixel. The color filter allows propagation of light having the wavelength within the first range of wavelengths and preventing propagation of light having the second wavelength within the second range of wavelengths.

Abstract: An electrowetting display comprises a support plate on which individual electrowetting pixels separated from one another by pixel walls are formed. Pixel walls including different layers are disposed on the first support plate and separate adjacent pixel regions from each other. The first layer of a pixel wall comprises a first material having a first color and a second layer of the pixel wall comprises a second material having a second color that is different from the first color. Instead of using black matrix to reduce photo crosstalk, the pixel walls of the different layers absorb light colors that are not intended to reach the respective pixels. A fluid is disposed between the first support plate and a second support plate and at least partially surrounds the first wall and the second wall.

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.
