  • Patent number: 11955049
    Abstract: A display panel and a corresponding driving method are provided, including at least an N?1th stage demultiplexing subcircuit and an Nth stage demultiplexing subcircuit. The N?1th stage demultiplexing subcircuit includes at least M N?1th stage demultiplexing units, wherein M and N are both integers not less than 2. By disposing at least two stages of the demuxing subcircuits in cascade, one signal can time-sharingly multiplex to a plurality of signals and correspondingly exponentially reduce a number of signal wirings.

  • Publication number: 20240105124
    Abstract: The present application discloses a display panel and a display device. The display panel includes pixel rows, auxiliary pixel driver circuits, main pixel driver circuits, and gate electrode driver circuits. Scan signal lines of each level include auxiliary scan signal lines of a number Q. Connecting first auxiliary scan signal lines of a number Z of the auxiliary scan signal lines of a number Q to corresponding ones of the gate electrode driver circuits and setting an end of second auxiliary scan signal lines to float prevents setting a connection wire connecting two of the auxiliary scan signal lines to avoid coupling.

  • Publication number: 20230066643
    Abstract: A display panel and a display device are provided. In the display panel, at least one odd-numbered thin film transistor is sequentially turned on to charge sub-pixels of a corresponding odd-numbered row before charging sub-pixels of any one of odd-numbered rows is finished, and at least one even-numbered thin film transistor is sequentially turned on to charge sub-pixels of a corresponding even-numbered row before charging sub-pixels of any one of even-numbered rows is finished, thereby saving the number of uses of data traces and thin film transistors, as well as enhancing the timeliness of data signal transmission.

  • Publication number: 20220190085
    Abstract: A display panel and a display device are provided, which include a substrate, a plurality of data lines, a semiconductor layer, a first connecting hole, and a second connecting hole. The first connecting hole and the second connecting hole are positioned on two adjacent data lines, and the semiconductor layer in two adjacent areas has a mirror image arrangement with respect to a first direction. Therefore, connecting data signal lines to the semiconductor layer by bridging can be prevented, and problems of dense wirings, small adjustment space for pixel design, and greater crosstalk between circuits can be solved.
