Driving circuit, driving current control method and processor

A driving circuit, a driving current control method and a processor provided by the invention relate to the technical field of light-emitting diode driving. The driving circuit is used for driving a passive light-emitting diode matrix circuit which includes a plurality of light-emitting diodes distributed in a matrix. The driving circuit includes a current source, a processor, and a control circuit. The processor is used for making the current source output the same current in each preset duration of the same period so that the light-emitting diodes lighted up in the period are of the same brightness, and the processor can make the current source output at least two currents of different amplitude in a preset duration. By making the current source output at least two currents of different amplitude in a preset duration, the problem in the prior art that the design of the driving circuit needing to output a driving current of any amplitude is very complicated is solved. 本发明提供的驱动电路、驱动电流控制方法及处理器，涉及发光二极管驱动技术领域。其中
