  • DRIVING DEVICE AND DRIVING METHOD THEREOF
    Publication number: 20190200428
    Abstract: A driving device and a driving method are provided. The driving device includes at least one driving signal generator, respectively coupled to at least one light emitting diode string, respectively, and respectively generates at least one driving signal to drive the light emitting diode string. At least one detection device is coupled to a detection point of the respective light emitting diode string and the respective driving signal generator, and compares the detection voltage of the corresponding light emitting diode string on the detection point with the detected voltages on the detection points of a plurality of remaining light emitting diode strings. Each of the driving signal generators determines whether to generate the driving signal according to the detection result of the corresponding detection device.
