Abstract: An electrowetting display device includes a plurality of pixels and a packaged integrated circuit that includes an output pin configured to electrically connect to a display driver, a rendering engine configured to output an initial luminance value for a first pixel in a plurality of pixels, and a memory controller. The memory controller includes a first frame buffer storing a current luminance value for the first pixel, a second frame buffer, and a front-end interface controller configured to encode a next luminance value. The next luminance value is at least partially determined by the initial luminance value for the first pixel. The memory controller includes a back-end interface controller configured to transmit a data signal through the output pin to the display driver to cause the display driver to apply a driving voltage to the first pixel. The driving voltage is at least partially determined by the current luminance value.

Abstract: An electrowetting element comprising a first support plate, a second support plate and a first and second fluid located between the first support plate and the second support plate, the second fluid immiscible with the first fluid. The first support plate comprises a wall extending along at least part of a perimeter of the electrowetting element and an electrode comprising a first electrode portion having a first electrode portion area and a second electrode portion having a second electrode portion area larger than the first electrode portion area. The first electrode portion is closer to the second support plate than the second electrode portion. The first electrode comprises a first edge portion and a second edge portion positioned further from an inner surface of a wall in a direction substantially perpendicular to the inner surface of the wall than the first edge portion.

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 of driving an electrowetting display device having at least one display element for displaying a display effect during a display period. The method determines a change in the display effect. Depending on the change, the display may be driven using a first driving scheme or a second driving scheme. The second driving scheme applies a voltage indicative of the display state a different number of times during the display period than the first driving scheme.
