摘要： A display device is provided with a display panel on which a plurality of display pixels are provided; a backlight illuminating the display panel; and a display panel driver driving the display panel. The display panel driver externally receiving image data and a clock signal for controlling timings of receiving the image data. The display panel driver includes a backlight controller generating a PWM-modulated drive signal to drive the backlight. The frequency of the PWM-modulated drive signal is dependent on a frequency-divided clock signal generated by frequency dividing of the clock signal externally received. The frequency-divided clock signal is generated so that the frequency of the PWM-modulated drive signal is kept constant when the frequency of the clock signal externally received is switched.
