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.

Abstract: A gate driver on array (GOA) circuit and a display panel are provided. The GOA circuit includes multi-stage cascaded GOA units, and each GOA unit includes a bootstrap module. The bootstrap effect of the bootstrap module is utilized to increase the gate voltage of the output transistor, which can effectively reduce the rise time and fall time of the scan signal output by each GOA unit, thereby improving the charging capability of the display panel.

Abstract: A display panel and an electronic apparatus are provided. The display panel includes a substrate comprising a display section, a binding section, and a fan-out section disposed between the display section and the binding section. By disposing a first detecting module on the binding section, and a second detecting module on a side of the fan-out section adjacent to the display section to test whether the signal wires is normal, waste of back-end materials caused by broken signal wires is prevented, and product yields are increased.

Abstract: A gate driver on array (GOA) circuit and a display panel are provided. The GOA circuit provides a pull-up maintaining module including transistors T11, T12, and T13. In a pre-charge sub-phase t1 and an output sub-phase t2, a node Qb is at a high level to pull down a node P and turn off the transistor T13. A node K changes to the high level under control of the transistor T11. The transistor T12 is turned on, and the node Qb is keeping at the high level. A node Qa is keeping at the high level in the pre-charge sub-phase, and keeping at a bootstrap electrical level in the output sub-phase.

Abstract: The present application provides a liquid crystal display panel and a display device. Invalid pixels of the liquid crystal display panel include a test pixel. In this structure, when no tests are required, the test pixel is in an off state, and there is no voltage difference between a pixel electrode and a common electrode to cause rotation of liquid crystals. When a test is required, the test pixel is in an on state, and the pixel electrode is disconnected from the common electrode to cause a voltage difference, so that the liquid crystals are normally rotated.
