The present disclosure relates to an LED driving technique. The present disclosure provides a technique of measuring a time for reaching a forward voltage of a currently driven LED by comparing a forward voltage sensed in a previous scan line and an LED voltage sensed in a current scan line and for compensating for an ON period of a PWM (pulse width modulation) signal by the measured time for reaching the forward voltage.
