Abstract
The present invention discloses an interface circuit of a display panel and a display panel. The interface circuit of the display panel is connected with a source driver, comprising: a constant current source; a first resistor; a first triode, a gate electrode connected to a first signal input terminal, a source electrode connected to a first terminal of the constant current source, and a drain electrode connected to a first input terminal of a receiving circuit, wherein, the first input terminal of the receiving circuit is connected to a first voltage of the source driver via the first resistor; a second resistor; a second triode, a gate electrode connected to a second signal input terminal, a source electrode connected to a second terminal of the constant current source, and a drain electrode connected to a second input terminal of the receiving circuit, wherein, the second input terminal of the receiving circuit is connected to the first voltage of the source driver via the second resistor. The present invention can effectively reduce the power consumption in a differential signal circuit.
