Claim 0:
1. A drive circuit, comprising:
a first module, generating display data based on image information;
a second module, generating a display signal based on the display data and a plurality of clock signals;
a third module, outputting a constant current based on the display signal; and
a fourth module, configured to provide a reference current to the third module, wherein
the fourth module comprises: a reference voltage generation module, a bias module, a current generation module, and a pre-charging module, wherein the reference voltage generation module is configured to provide a reference voltage to the bias module, the bias module is configured to provide a bias current to the current generation module and provide a bias voltage to the pre-charging module, and the current generation module is configured to provide a reference current to the third module; and
any two adjacent clock signals of the plurality of clock signals differ by M complete clock cycles, 0≤M<1.
