Abstract: In general, techniques are discussed for performing efficient content scrolling on smartphones and other user devices. Power and memory bandwidth requirements are reduced during high-speed scrolling by utilizing lossy compression of content during rendering with minimal user experience impact, as the user is less likely to notice artifacts resulting from high compression while the content is scrolling quickly.

Abstract: Techniques are provided for optimizing display processing of layers below a dim layer by a display system. Because the dim layer may partially obstruct, conceal, or otherwise impact a user view of layers below the dim layer, resource-saving techniques may be used in the processing the layers below the dim layer. While these techniques may impact visual quality, a user is unlikely to notice visual artifacts or other reductions in quality in the modified layers below the dim layer. For example, when a dim layer is to be displayed, a GPU can render layers below the dim layer at a lower resolution. Furthermore, the GPU can increase a compression ratio for layers below the dim layer. The low-resolution layers can be scaled-up to an original resolution and the compressed layers can be uncompressed in the display pipeline for display underneath the dim layer.

Abstract: A device includes a display client configured to output pixel data at a display and a processor. The processor is configured to determine a composition of one or more layers for display at the display client. The processor is further configured to select a video mode or a command mode as a selected mode, based on the determined composition. Pixel data for each frame to be displayed is output to the display client when operating in the video mode. Pixel data for frames that include different pixel data for at least one pixel than a previously output frame is output to the display client when operating in the command mode. The processor is further configured to output an instruction to operate in the selected mode.

Abstract: Methods, systems, and devices for refreshing a display of a device are described. A device may identify a type of content to be displayed. For example, the type of content may be associated with a given application. The device may determine, based at least in part on the type of content, a periodicity for a histogram analysis operation for the display. The device may then perform the histogram analysis operation according to the periodicity. For example, the device may compare a histogram for a frame of the content to a scene change threshold according to the periodicity. The device may determine one or more pixel adjustment parameters for the display based at least in part on the histogram analysis operation. The device may display one or more frames on the display based at least in part on the one or more pixel adjustment parameters.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, an example method may include determining, by a first processing unit, display luminance information and ambient light information. The display luminance information may be indicative of a luminance of a backlight of a display or indicative of pixel luminance of the display. The ambient light information may be indicative of a luminance of ambient light external to the display. The method may include enabling or disabling, by the first processing unit, a first display feature for the display based on the display luminance information and the ambient light information.

Abstract: Techniques are described for controlling the display refresh rate of a display panel. A display driver may determine a display refresh rate based on user activity. One example of user activity is a rate at which a user is scrolling image content being displayed on the display panel. One example of user activity is a duration or pressure of a user interaction with a display panel or a pressure sensor.

Abstract: The techniques of this disclosure include initiating, by a source device associated with a primary display device, a wireless display session with an external display device. Furthermore, the source device may change from a dual update mode to an external-only update mode during the wireless display session. Based on the source device operating in the external-only update mode during the wireless display session, the source device may discontinue generation of the primary stream and may continue generation of the external stream.

Abstract: A device includes a display client configured to output pixel data at a display and a processor. The processor is configured to determine one or more user input events based on user interaction data. The processor is further configured to select a video mode or a command mode as a selected mode, for operating the display processor, using the quantity of touch events. Pixel data for each frame to be displayed is output to the display client when operating in the video mode. Pixel data for frames that include different pixel data for at least one pixel than a previously output frame is output to the display client when operating in the command mode. The processor is further configured to output an instruction to operate in the selected mode.

Abstract: Techniques are described for reducing the number of fetches performed when a background layer (e.g., letter or pillar box) to be displayed is of a constant fill color. One or more processors (e.g., a display processor) may be configured to detect that a background layer is of a constant fill color. If so, rather than fetching the background layer from memory, the one or more processors may be configured to generate the constant fill color for the background layer. In doing so, there may be a reduction in the number of memory fetches performed, as the constant fill background layer is not fetched or is only partially fetched. This may reduce memory fetch operations (as only the video layer is fetched) and therefore power savings (e.g., battery usage) at memory and bus interfaces, decreased use of the bandwidth at the bus and memory, and decreased processor usage.

Abstract: A system of the present invention enables the running of browser based, pluggable Big Data Applications powered by intelligent workflows. The system receives from a user computer browser application a request for execution of a workflow. The request is submitted for execution of the workflow to the Spark® cluster as a Spark® job including information about the workflow details. The result of the execution of the workflow is received from the driver running on the Spark® cluster after each node of the workflow request has been executed on the Spark® cluster. A JSON/XML-format files containing the received results of the execution of the workflow is then created, such that when the JSON/XML format files are processed by the user computer web browser, the results are displayed on the user computer as rich text/table/chart/tree visual displays.
