Abstract: Certain aspects of the present disclosure provide methods and apparatus for configuring an image data transfer time for sending image data from a processor to a display panel along a display path. For example, one disclosed method includes receiving, by the processor from the display panel, a display panel refresh interval indication indicating a display panel refresh interval of the display panel, the display panel refresh interval of the display panel corresponding to a time duration of a display period of the display panel. According to the method, the display panel is configured to refresh each display period. The image data transfer time is computed based on the display panel refresh interval. One or more components of the display path are configured to support the computed image data transfer time.

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.
