Abstract
The invention provides a low power multiplexer configuration in a display panel and a display panel and an electronic device using the same. The multiplexer conducts one of source output signals into to red (or green or blue) sub-pixels under control of control signals. In every time a frame is scanned or changed, the red (or green or blue) sub-pixels driven by the source output signal via the multiplexer are always in the same signal polarity, so the multiplexer consumes low power because voltage swing rates in source output signals are very low or almost zero.
