A driving circuit and a method for driving a display panel are proposed. The driving circuit includes: a clock controller; a scan signal driver for generating a first scan signal and a second scan signal; a data signal driver for receiving a source data signal, and generating a first data signal, and generating a second data signal based on the first data signal. A gray level value corresponding to the first data signal is different from a gray level value corresponding to the second data signal. The present invention is able to reduce color shift.
