Title: DATA INDEPENDENT CHARGE SHARING FOR DISPLAY PANEL SYSTEMS
Abstract:
A display panel subsystem includes a timing controller configured to employ a charge sharing scheme during a current display data polarity period by using a row completion signal to invoke charge sharing for groups output channels included in a display panel. The timing controller determines the polarity state setting of the source drivers of the display panel during a polarity period and generates a charge sharing enable signal responsive to receiving a row completion signal. During charge sharing, for each source driver having the same polarity state setting during the polarity period, the charge sharing enable signal operates to connect output of a source driver to the output of one or more source drivers included in a group of source drivers with a common polarity state.
