Abstract
An anti-interference display panel includes a source driving chip, a switching signal line, a multiplexer, and an anti-interference signal line. The source driving chip is configured to generate a data signal. The switching signal line is configured to transmit a switching signal. The multiplexer is configured to receive the data signal and the switching signal, and is configured to output the data signal according to the switching signal. The anti-interference signal line is configured to transmit an anti-interference signal. An equivalent resistor and an equivalent capacitor are formed on the anti-interference signal line, and resistance of the equivalent resistor is approximate to resistance of a load resistor coupled to the switching signal line, and capacitance of the equivalent capacitor is approximate to capacitance of a load capacitor coupled to the switching signal line. A voltage of the anti-interference signal falls when a voltage of the switching signal rises, and rises when the voltage of the switching signal falls.
