Abstract

A driving device and an operation method thereof are provided. The driver device includes a source driver circuit, an output switching circuit, and an equalization control circuit. Two input ends of the output switching circuit are coupled to two output ends of the source driver circuit. Two output ends of the output switching circuit are coupled to two data lines of an LED display panel. The equalization control circuit checks whether sub-pixel data of the two data lines meets a predetermined condition. A plurality of sub-pixels located on a current display line of the LED display panel are reset in a reset period. In a data scanning period after the reset period, the equalization control circuit determines whether to control the output switching circuit to perform an equalization operation on the two data lines according to the checking result.
