Abstract

A display device (100) includes a row driver (520) configured to provide a row voltage, and a row electrode (320) connected to the row driver (520). A column driver (530) is configured to provide N column voltage levels to a column electrode (330). Further, a common electrode driver (570) is configured to provide M common voltage levels to a common electrode (170). A pixel (CDE) is connected between the column electrode (330) and the common electrode (170); and a controller (515) is configured to control timing of application of the N column voltage levels relative the M common voltage levels to provide NM effective pixel voltage levels across the pixel (CDE).
