Abstract: A display device includes a row driver configured to provide a row voltage, and a row electrode connected to the row driver. A column driver is configured to provide a column voltage to a column electrode. Further, a common driver is configured to provide a common electrode that includes a negative level. In addition, a controller is configured to switch the common electrode between at least two levels when all rows have a non-select level of the row voltage. The controller may be further configured to switch the common electrode at a substantially same time and with a substantially same voltage swing as a storage voltage of a storage capacitor.

Abstract: A method of controlling an electronic display having a plurality of pixels settable in a first operating level, a second operating level and an intermediate operating level, the method comprising the step of setting the pixels in a preparatory intermediate operating level immediately prior to setting the pixels in a desired intermediate operating state. At an end of a frame i?1, for example, it is possible to drive a pixel from a level P0 further towards white to reach reflection level Pn or to stop driving it, or to switch a control voltage to an apposite polarity and arrive at a lower level. Levels P1 and P2 present embodiments of preparatory intermediate levels used to drive pixels in accordance with the invention. For example, levels 2, 4, and 6 may be obtained from the preparatory level P1. Levels 3, 5, and 7 may be obtained from the preparatory level P2.
