Using PWM (pulse-width modulation, a technology where the intensity of the LEDs are kept constant, but the brightness adjustment is achieved by varying a time interval of flashing these constant light intensity light sources [26]), the backlight is dimmed to the brightest color that appears on the screen while simultaneously boosting the LCD ...
