DISPLAY DEVICE AND METHOD FOR CONTROLLING DISPLAY DEVICE

摘要

A display device has a display panel and a backlight unit. The backlight unit includes first and second light source units, and a control unit that outputs a drive signal to the light source units to drive the first and second light source units during first and second drive periods in one frame period respectively. The control unit drives the light source units so that the one frame period has an overlapped period, in which the first and second drive periods overlap. The control unit outputs PWM signals to turn the light source units on and off to the light source units respectively. The control unit shifts a phase of the PWM signal to be outputted to the first light source unit and a phase of the PWM signal to be outputted to the second light source unit from each other.
