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: 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: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for monitoring interception of an image display pipeline and indicating a determined interception to a user. A display processor may detect that at least one application is activated based on one or more CRC values that correspond to the at least one application. The display processor may generate a UI indication for the at least one application based on detecting that the at least one application is activated and transmit, based on generating the UI indication, at least one UI layer. The at least one UI layer may correspond to the UI indication for the at least one application.

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.
