  • DISPLAY APPARATUS AND METHOD OF ADJUSTING BRIGHTNESS THEREOF
    Publication number: 20190228721
    Abstract: A display apparatus includes a backlight source, a display panel, and a first backlight driver and a second backlight driver respectively coupled to the backlight source. The first backlight driver is further coupled to a pulse width modulation (PWM) signal generator, and is configured to drive the backlight source to emit light through a PWM signal output by the PWM signal generator, so that a brightness value of the display panel is within a first brightness range. The second backlight driver is further coupled to the PWM signal generator, and is configured to drive the backlight source to emit light through a PWM signal output by the PWM signal generator, so that the brightness value of the display panel is within a second brightness range.
