Abstract: Methods, apparatus, systems, and articles of manufacture for applying selective adjustment of displays are disclosed herein. An example apparatus to control an operating characteristic such as a brightness of a display of an electronic device includes a face analyzer to identify a presence of a face of a user relative to the device based on image data generated by an image sensor of the electronic device, and a correlation analyzer to determine a correlation of the detected presence and a first device interaction event. In response to the correlation, the correlation analyzer is to apply a display brightness adjustment rule to selectively adjust the brightness of the display from a first setting to a second setting after a first time interval.

Abstract: Techniques for selective display frame fetching can include receiving or fetching rendered display frames by a display engine. The display engine can obtain an indication of a new frame and, in response to the indication of the new frame not including an indication of a flip completion event: (i) fill the display buffer with the new frame; (ii) scan out the new frame from the display buffer to a display port; and (iii) apply an adaptive contrast and backlight enhancement based on a histogram of changes in the new frame.

Abstract: Technology for a display controller is described. The display controller can detect a frame update when the display controller is in a dynamic sleep state. The display controller can wake up from the dynamic sleep state and enter a selective update state at a programmed vertical blanking interrupt (VBI) that precedes an actual VBI. The display controller can perform a scan-out with a display panel during the selective update state. The display controller can return to the dynamic sleep state in a same time frame after the scan-out is completed. The display controller can exclude timing logic to send a VBI at every time frame to the display panel to maintain time synchronization between the display controller and the display panel.

Abstract: Techniques for selective display frame fetching can include receiving or fetching rendered display frames by a display engine. The display engine can determine if a new frame includes one or more dirty portions. If the new frame includes one or more dirty portions, just the dirty portions can be loaded by the display engine into a display buffer. The display engine can also scan out just the dirty portions from the display buffer to a display.

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed for reduced computing device power consumption. Example methods disclosed herein includes detecting frame updates corresponding to input frames to be presented by a display, causing a programmable timer to generate second interrupts corresponding to first interrupts generated by a display engine, the second interrupts to be generated when there are no frame updates detected for at least a first duration of time defined by a first threshold. Example methods further include causing the display engine to transition to a low power state when (1) the programmable timer is configured to generate the second interrupts and (2) no frame updates have been detected for at least a second duration of time following the first duration of time, the second duration of time defined by a second threshold.
