摘要：
A display device with a pulse width modulation system in the invention includes a current measuring circuit for measuring a peak current value of a pixel, a reference current value calculating circuit for calculating a reference current value according to at least one of cumulative use time of the pixel and a degraded condition of the pixel, and an anode power supply circuit for controlling the peak current value of the pixel, aiming for the reference current value as a target.
