RELAY DRIVING OF 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 a plurality of lines of display pixels, wherein the first signal is an AC signal;
scanning a first set of the lines of display pixels of the first group while not applying an AC 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 a plurality of lines of display pixels different than the first group;
applying a second signal to the common electrode associated with each of the plurality of display pixels in the second group, wherein the second signal is an AC signal;
scanning a second set of the lines of display pixels of the first group while the first and second signals are being applied;
discontinuing 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.
