Abstract: Subject matter disclosed herein relates to improving luminance and reducing color shifts in electrowetting displays. The electrowetting display comprises a plurality of electrowetting elements separated by partition walls and spacers. The spacers and/or partition walls are reflective. When incident light that enters a pixel or subpixel is reflected and encounters a spacer and/or partition wall, the light is reflected such that the reflected light exits the pixel or subpixel into which the incident light entered. This improves luminance and reduces color shifts of the electrowetting display.

Abstract: A method for fabricating an electrowetting display may include forming pixel electrodes on a support plate; depositing a first layer on the pixel electrodes; etching portions of the first layer to form pixel walls that partition pixel regions; depositing a second layer on the pixel electrodes and the pixel walls; etching portions of the second layer to form spacers on tops of the pixel walls; and depositing a hydrophobic layer to at least partially cover the pixel electrodes.

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: An electrowetting display device may comprise pixels that include: a hydrophobic layer portion disposed on a first electrode, electrowetting fluids overlying the hydrophobic layer portion, and a thin film transistor (TFT) that is in electrical contact with the first electrode. The electrowetting display device also comprises a display control circuit in electrical contact with a drain or a source of the TFT of each of the pixels to provide a drive voltage to the drain or the source of the TFT of each of the pixels, and a reset control circuit in electrical contact with the drain or the source of the TFT of each of the pixels to provide a reset voltage pulse to the drain or the source of the TFT of each of the pixels. A magnitude of the reset voltage pulse may be based, at least in part, on the drive voltage.

Abstract: An apparatus comprising an electrowetting display element comprising a radiation filter, a first support plate, a second support plate, a first fluid and a second fluid immiscible with the first fluid. The apparatus comprises at least one processor and at least one memory comprising computer program instructions operable to, with the at least one processor: determine, based on an input signal indicative of a characteristic of an input to the apparatus, that a predetermined condition for reduction of an exposure of the first fluid to incident light is satisfied; and, in response, generate an output signal to control the electrowetting display element to configure the first fluid in a retracted configuration with the first fluid at least partly overlapped by the radiation filter and with both the first fluid and the second fluid in contact with a surface of the first support plate.

Abstract: An electrowetting display device may comprise rows and columns of pixels. Each of the pixels may include a thin film transistor (TFT) that is switchable to select each of the pixels using active matrix addressing. The electrowetting display device may further comprise source lines connected to the TFT of each of the pixels; gate lines connected to the TFT of each of the pixels; and a supplemental capacitor disposed between each of the gate lines and a ground and having a capacitance approximately equal to an equivalent capacitance of a group of pixels that are interconnected with one another on one of the gate lines, wherein the group of pixels are a subset of the rows and columns of pixels.
