Inverter for boosting rotational image displaying gain

An inverter, comprising:

• a driving module to output a driving signal;
• and
• a plurality of voltage transformation modules to receive the driving signal and transform an input power to a high voltage output power to drive a discharge lamp connecting to a rear end;
• wherein the driving signal of the driving module has a same frequency and a same phase to synchronously drive the voltage transformation modules, the driving signal having a duty cycle consisting of high luminance cycles and low luminance cycles, so that the voltage transformation modules operate continuously without interruption to drive the discharge lamp in a dim-bright-dim manner as a result of the duty cycle of high luminance cycles and low luminance cycles the driving module including a time sequence control means which codes the driving signal that drive the voltage transformation modules corresponding to image display time of a front end display panel, the display panel having a transformation time difference between a preceding image and a following image that is coded as the low luminance cycles.
