Abstract:
A source driver of a display panel includes a channel state signal generator, first switches, and second switches. The channel state signal generator generates first and second channel state signals that are each activated for a respective time period depending on adjustable state length data. The first switches are opened for uncoupling channel output signals from source lines of the display panel when the first channel state signal is activated. The second switches are closed for coupling together the source lines of the display panel for charge sharing when the second channel state signal is activated.
