Abstract
A signal regulator module includes a floating current regulator, a signal sensor, and a feedback controller. The floating current regulator is electrically coupled to a driving circuit and the light sources of a display panel for regulating the driving signals based on a feedback signal in a photo couple means. The signal sensor is electrically coupled to the floating current regulator for generating a corresponding voltage signal based on the driving signal through a photo couple means. The feedback controller is electrically coupled to the signal sensor and the floating current regulator for generating the feedback signal based on the voltage signal and outputting the feedback signal to the floating current regulator.
