Claim Text:
1. A driving circuit, for driving a display panel to display an image; the display panel comprising a plurality of display units and a plurality of scanning lines; each scanning line connected to a plurality of display units; the scanning lines configured to transmit scanning signals provided by a scan driving circuit to the display units; the display units being activated to display the image, based on the scanning signals; the driving circuit comprising: a clock signal generating unit, configured to generate clock signals, each of the clock signals comprising a plurality of first levels and a plurality of second levels, wherein the first levels and second levels are alternately output, a potential of each first level is different from a potential of each second level, transitions from each first level to each second level are for triggering the scan driving circuit to generate the scanning signals, the transitions from each first level to each second level are defined as effective signal edges of the clock signals, and an interval between adjacent effective signal edges is defined as a clock time interval; and a control unit, configured to control the clock time intervals of each clock signal to be non-identical, the clock time intervals comprising a first clock time interval and a second clock time interval, the second clock time interval being longer than the first clock time interval; and the control unit further configured to control the clock time interval to be the second clock time interval at least once during a process of displaying one frame of image by the display panel, wherein the clock signal generating unit comprises: an initial pulse generating module configured to generate an initial pulse; a clock signal generating module configured to generate the clock signal based on the initial pulse; and a reset signal generating module configured to generate a reset signal, wherein the reset signal is for controlling the initial pulse generating module to output the initial pulse again after a third preset time duration; and wherein the control unit is connected to the reset signal generating module, and is configured to control the reset signal generating module to generate the reset signal at least once during the process of displaying one frame of image by the display panel, to make the clock time interval of the clock signal output from the clock signal generating module to be equal to the second clock time interval.
