  • Patent number: 10679580
    Abstract: The present disclosure provides a pixel circuit, a driving method thereof and a display panel. In the pixel circuit, the storage module stores a written data signal at a first node, and then the potential of the second node is controlled according to the stored data signal, so that the pixel circuit outputs a driving signal for driving a pixel unit to emit light under the control of key nodes (i.e. the first node and a second node) to achieve normal light emission of the pixel. When the pixel circuit is applied in a display device, the data signal stored by the storage module may replace a data signal input from a data line when a still picture is displayed.

Additionally, the pull-down sub-circuit is configured, under control of power signals, to pull down the voltage level at the output port. For the display-touch panel with full-in-cell touch sensors, the voltage level at output port can be effectively reduced to avoid mutual interference between drive signals and touch-control signals.
