摘要：
A converter includes a feedback part, a pulse width modulation (PWM) controller and a PWM generator. The feedback part is configured to output a feedback signal based on a driving voltage. The PWM controller is configured to output a PWM control signal based on the feedback signal and a first compensation signal. The PWM generator is configured to control the driving voltage based on the PWM control signal. The first compensation signal is determined according to an occurrence of a predetermined pattern of an input image data.
