CHARGE SHARING METHOD FOR REDUCING POWER CONSUMPTION AND APPARATUSES PERFORMING THE SAME

摘要

A charge sharing method, device, and system is disclosed. For example, a charge sharing method for a display driver is disclosed. The method includes: receiving a first row of data for a first row of source lines; receiving a second row of data for a second row of source lines; for each source line of at least a first group of the source lines, determining whether a change amount between data for that source line from the first row of data and data for that source line from the second row of data is above a threshold; and performing selective charge sharing based on the determinations.

1. A charge sharing method for a display driver that uses Z-inversion, the method comprising:
receiving a first row of data for a plurality of source lines; receiving a second row of data for the plurality of source lines; for each source line of the plurality of source lines, determining whether a change amount between data for that source line from the first row of data and data for that source line from the second row of data is above a threshold; and controlling whether to perform charge sharing among a first group of source lines of the plurality of source lines based on the determinations for that first group of source lines.
