1. A method of updating rows of pixels in a display panel, the method comprising:
- assigning rows of pixels in the display panel to one of a plurality of update sets, each update set including a sequence of rows such that each row in the sequence is separated from a next row in the sequence by at least one row;
applying a common voltage to a set of electrodes in the display panel, the common voltage adapted to switch between two voltage levels; and
updating the pixels in the rows of an update set each time the common voltage applied to the set of electrodes switches voltage levels, wherein at least one row in one of the plurality of update sets updates before another row in the same update set updates a second time.

Abstract
Methods and apparatus for switching the voltages supplied to the electrodes of pixels disposed within a liquid crystal display device. By reducing the frequency associated with an alternating voltage supplied to a first set of liquid crystal electrodes, the power required to drive the liquid crystal display device can be reduced. At the same time, a reordered schedule for updating rows of pixels in the liquid crystal display device can provide improved image quality.

8. A display apparatus, comprising:
one or more display driver circuits communicatively couplable to an array of display pixels in a display panel, the one or more display driver circuits capable of assigning rows of pixels in the display panel to one of a plurality of update sets, each update set including a sequence of rows such that each row in the sequence is separated from a next row in the sequence by at least one row, applying a common voltage to a set of electrodes in the display panel, the applied voltage adapted to switch between two voltage levels, and updating the pixels in the rows of an update set each time the voltage applied to the electrodes switches voltage levels, wherein at least one row in one of the plurality of update sets updates before another row in the same update set updates a second time. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
