Abstract:
The present disclosure provides an electrostatic protection circuit and a display panel, wherein the electrostatic protection circuit includes a first voltage reference unit configured to divide a voltage between an array substrate row driving signal line and a common electrode line once; a second voltage reference unit configured to divide the voltage between the array substrate row driving signal line and the common electrode line twice; and a charge releasing unit that adjusts charge distribution between the array substrate row driving signal line and the common electrode line based on reference voltages provided by the first voltage reference unit and the second voltage reference unit.
