Driving circuit of optoelectronic equipment and driving method thereof

The invention is suitable for the technical field of electronics and provides a driving circuit of optoelectronic equipment and a driving method thereof. The driving circuit comprises a first series-to-parallel conversion chip and a second series-to-parallel conversion chip, wherein the first series-to-parallel conversion chip is connected with a singlechip through a three-wire bus and is used for converting serial data output by the singlechip into parallel data and outputting the parallel data to the section control end of the optoelectronic equipment; and the second series-to-parallel conversion chip is used for converting the serial data spilled by the first series-to-parallel conversion chip into the parallel data and outputting the parallel data after the conversion to the position gate end of the optoelectronic equipment to control the data of the display section of the optoelectronic equipment. According to the invention, multiple series-to-parallel conversion chips are connected between the singlechip and a digital tube, and the serial-in-parallel-out conversion of data is completed through the series-to-parallel conversion chips, thereby achieving the control of the driving optoelectronic equipment by only using the three-end bus, reducing the occupancy rate of the I/O (input/output) port of the singlechip so that more control tasks can be completed at the limited I/O port of the singlechip, simplifying a circuit and improving the reliability of the circuit.
