Zusammenfassung:A driving circuit, for driving a display panel of a display apparatus, includes a control module, a gamma-voltage generation module, and a conversion outputting module. The control module provides a first control voltage and a second control voltage which are adjustable. The first control voltage is higher than the second control voltage. The gamma-voltage generation module generates a gamma voltage according to the first control voltage and the second control voltage. The conversion outputting module converts the gamma voltage into a driving voltage and outputs it to the display panel. When the display panel is over-loaded, the control module adjusts the first control voltage and/or the second control voltage to change the gamma voltage generated by the gamma-voltage generation module, and the driving voltage outputted by the conversion outputting module is changed accordingly to adjust a curve of a panel voltage on the display panel versus time.
