  • Patent number: 10373571
    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.
