Abstract: A multiplexed display panel and device and a driving method for the multiplexed display panel are provided. At the moment when a switching switch is turned on, a potential of a fanout line corresponding to a data line connected to sub-pixels, into which an data signal is input, is adjusted to the same level as a potential of the data line as much as possible, and a potential difference between each fanout line and the corresponding data line is relatively small at the moment when the switching switch is turned on, so that an instantaneous current at this moment is greatly reduced without causing relatively large jump of the potential of the data line, a common electrode and back-plated indium tin oxide (ITO) greatly fluctuate, and then the surface noise generated by the display panel is turned on is greatly reduced.

Abstract: A multiplexed display panel includes sub-pixels, gate line, data lines, and a demultiplexer. The demultiplexer includes input channels each provided with switching transistors and fanout lines. Each fanout line is correspondingly connected to one data line by one switching transistor to provide one data signal to the one data line. The one switching transistor corresponding to each input channel is controlled by a same control signal. While each gate line scans one row of the sub-pixels, when a rising edge of the control signal reaches an amplitude, and at a moment when the one switching transistor is controlled by the control signal to be on, the demultiplexer is configured to make a difference between a potential reached by a rising edge of one fanout line correspondingly connected to the one data line and a potential of the one data line to be less than a preset threshold.
