Abstract: The techniques of this disclosure include power optimal multiplexing of host and/or panel random access memory (RAM) pixel data for display scan out. Two aspects include systems and methods of bypassing the memory on the smart display panel in certain circumstances and refreshing the display from the host: hardware enhancement for an optimal block-based timing engine for smart display panels and an optimized frame-based timing engine scan out for smart display panels. The host may determine whether to bypass the memory of the smart display based on the size of high refresh rate regions and/or offline data for non-updating regions from the host and RAM respectively. By bypassing the panel RAM during circumstances where large areas of the display are updated rapidly, display power usage and on-panel RAM wear out may be reduced.

Abstract: Various embodiments include methods and devices for implementing a secure user interface. The method may include generating a secure user interface display in a secure execution environment, generating a non-secure display in a normal execution environment, combining the secure user interface and the non-secure display into a combined display, and presenting the combined display via a display device.

Abstract: Methods implemented on computing devices provide protections for sensitive information by outputting audio descriptions of sensitive information via a personal audio output device coupled to the computing device so that the description can be heard only by the user rather than displaying the information. Further protections for sensitive information may include displaying an input keypad on a touch-sensitive display in which key images do not include a visual indication of the character or value associated with each key, and outputting an audio description of the character or value associated with a user-selected key of the keys on the data input keypad via the personal audio output device so that the key description can be heard only by the user. Key audio descriptions may be output in response to a first keypad input, and a data entry may be processed in response to a second keypad input on the same key

Abstract: Techniques of this disclosure may include ways to control the amount of graphics data a graphics processing unit (GPU) renders. The GPU may render graphics data for image content that changed from frame-to-frame rather than graphics data for image content that changed and did not change. To display the image content, processing circuitry may map locations of where the graphics data is stored to lines in the image content allowing for the GPU to store the graphics data in arbitrary locations of an application buffer.
