Relay driving of conductive segments in displays
First Claim
1. A method of displaying an image on a display including a plurality of lines of display pixels, each display pixel being associated with a common electrode, the method comprising:
- applying a first signal to the common electrode associated with each of a plurality of display pixels in a first group of display pixels, the first group including one or more of the plurality of lines of display pixels, wherein the first signal is an alternating current signal;
scanning a first set of the lines of display pixels of the first group while not applying a second signal to the common electrode associated with each of a plurality of display pixels in a second group of display pixels, the second group including one or more of the plurality of lines of display pixels different from the first group, wherein the second signal is an alternating current signal;
applying the second signal to the common electrode associated with each of the plurality of display pixels in the second group;
scanning a second set of the lines of display pixels of the first group while the first and second signals are being applieddiscontinuing application of the first signal; and
scanning a third set of the lines of display pixels of the second group while the second signal is being applied.

Abstract
Multiple Vcom segments of display screens can be driven in a relay fashion, such that the driving of different Vcom segments overlaps. For example, a Vcom signal can be applied to a first segment of Vcom, and lines of display pixels in the first segment can be scanned. When scanning nears the end of the first segment, a Vcom signal can be applied to the next segment of Vcom before scanning in the first segment ends. For example, when the second-to-the-last line of display pixels in a segment of Vcom is scanned, the next Vcom segment can be driven with a Vcom signal. Likewise, when scanning in the next segment of Vcom begins, the Vcom signal can continue to be applied to the first segment of Vcom until a few lines of display pixels in the next segment have been scanned.
