    Abstract: An inverter control circuit is used to control a switch and a transformer in front of a light-emitting unit and then adjust the driving power for the light-emitting unit and modify the luminant state of the light-emitting unit and comprises: a first control unit and a second control unit both having equivalent electronic elements. The first control unit and the second control unit have a signal generator and a signal synthesizer circuit. According to a signal fed back by the light-emitting unit and a dimming signal, the first signal generator outputs first working signals via the signal synthesizer circuit of the first control unit to determine the turn-on time of the switch. According to the first working signals and via the signal synthesizer circuit of the second control unit, the second signal generator outputs second working signals to the switch to determine the resonance frequency of the transformer.

    Abstract: A backlight module actuation method aims to modulate a unsaturated luminance cycle in a dimming cycle for a backlight module in the condition of a saturated luminance. An oscillation amplitude time series of the duty cycle of a transformer at the rear end is set according to the dimming cycle to form a switch kinetic energy in the unsaturated luminance cycle. The switch kinetic energy can eliminate the parasite capacitance generated when the backlight module is in the condition of the saturated luminance.

    Abstract: An inverter for boosting rotational image displaying gain has a driving module to output a plurality of driving signals of the same frequency and same phase to synchronously drive a plurality of voltage transformation modules. The driving signals have a duty cycle consisting high luminance cycles and low luminance cycles. The driving module has a time sequence control means to code the driving signals that drive the voltage transformation modules as the high luminance cycles corresponding to the image display time of a front end display panel. The transformation time difference between the preceding image and the following image of the display panel is coded as the low luminance cycles. Thereby the rotational image displaying gain of the display panel can be enhanced.
