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.
