Abstract:
A control system for a portable display device includes a battery power supply powering a display panel of the portable display device, a backlight controller and a video processor connected to the display panel for displaying images, an adaptive controller providing output signals to the backlight controller and the video processor, a video analyzer providing a first input to the adaptive controller, and a remaining display time estimator providing a second input to the adaptive controller, wherein the remaining display time estimator determines a remaining display time of the portable display device and controls the adaptive controller to adjust one of the backlight controller and the video processor based upon the determined remaining display time.
