Mitigation of interference between FM radio and display subsystems on a mobile device

摘要

Systems and methods for mitigating interference or concurrency between frequency modulation (FM) radio subsystem and a display subsystem relate to determining potential concurrency between the two subsystems at particular FM modes of operation, and adjusting one or more display parameters of the display subsystem and additionally or alternatively, implementing filters in the FM subsystem in order to avoid or mitigate the potential concurrency. The FM modes comprise one or more FM operating bands or FM channels, and the display parameters comprise one or more of a display refresh rate, display clock frequency, and backlight brightness.

1. A method of reducing frequency modulation (FM)-display concurrency in an electronic device, the method comprising:
determining a FM mode of operation of a FM subsystem; determining a potential concurrency between a display subsystem and the FM subsystem based on the FM mode of operation; adjusting one or more display parameters of the display subsystem in order to avoid the potential concurrency; and lowering a threshold for required received signal strength for the FM subsystem, based on the one or more display parameters of the display subsystem adjusted to avoid the potential concurrency.
