Abstract
A method includes detecting, through a processor communicatively coupled to a memory, coupling of an external display to a data processing device including an internal display, and cloning, through the processor, display data of the internal display on the external display following the detection of the coupling. The method also includes triggering, through a driver component, the processor to turn off a backlight of the internal display of the data processing device, power gate circuitry associated with rendering the display data on the internal display and/or power gate a processing pipeline associated with the rendering of the display data following the cloning. Further, the method includes maintaining, through the driver component, a touchscreen capability of the internal display even when the backlight is turned off, the circuitry associated with the rendering of the display data is power gated and/or the processing pipeline associated therewith is power gated.
