Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for composition strategy searching based on dynamic priority and runtime statistics. A CPU may determine, based on a plurality of frames, a usage frequency of each of one or more composition groups. The one or more composition groups may be used for composing the plurality of frames. The CPU may subsequently assign/update a priority for each of the one or more composition groups based on the usage frequency, such that the CPU may analyze, as part of a frame composition procedure, at least one of the one or more composition groups in an order that is based on the priority of the one or more composition groups.

Abstract: Embodiments include methods and devices for per layer motion adaptive over-drive strength control for a display panel. Various embodiments may include determining motion information associated with a frame layer, determining an over-drive strength factor for the frame layer based at least in part on the motion information associated with the frame layer, and determining whether the over-drive strength factor is associated with computing a content difference. Various embodiments may include, in response to determining that the over-drive strength factor is associated with computing a content difference, performing fragment shading on the framebuffer object for the frame layer to generate an over-drive compensated framebuffer object for the frame layer based at least in part on the over-drive strength factor, and outputting the over-drive compensated framebuffer object for the frame layer to a default framebuffer for rendering on the display panel.

Abstract: The present disclosure relates to methods and devices for display processing including an apparatus, e.g., a display processor. In some aspects, the apparatus may store one or more pixel conversion factors for at least one display panel. The apparatus may also determine whether to switch from a previous frame refresh rate to an updated frame refresh rate at the at least one display panel. Additionally, the apparatus may identify, upon determining to switch from the previous frame refresh rate to the updated frame refresh rate, a pixel conversion factor of the one or more pixel conversion factors associated with the updated frame refresh rate. The apparatus may also refresh the at least one display panel based on the updated frame refresh rate associated the pixel conversion factor.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may attempt to establish a data session with a base station. The UE may transmit one or more session request messages including one or more route selection descriptors (RSDs) to the base station, and the UE may determine a successful RSD that may be compatible with the network based on a session accept message received from the base station. The UE may store the successful RSD at a location in memory for use in future session establishment procedures. For example, the UE may go out of service, and may re-acquire service with the same network. In such cases, the UE may transmit a session request message including the previously-accepted RSD to re-establish a data session with the base station.

Abstract: Systems, methods, and apparatus for controlling radio frequency (RF) interference at a mobile communication device are described. A data communication apparatus has a wireless transceiver configured to transmit and receive RF signals, a bus interface circuit coupled to a serial bus and configured for operation as a display serial interface (DSI), and a controller. The controller is configured to receive a measurement of a reference signal representative of RF signal quality at the mobile communication device, determine whether the measurement of the reference signal indicates that the RF signal quality is less than a minimum RF signal quality level, and reduce signal strength of a transmitter in the bus interface circuit when the RF signal quality falls below the minimum RF signal quality level.
