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.
