Processor for use in dynamic refresh rate switching and related electronic device

An electronic device capable of displaying, having capability of switching a refresh rate for refreshing a display panel, comprising:

• a display panel, capable of display frames with a plurality of a refresh rates;
• a processor, configured to dynamically transition between different states/scenarios in response to different triggering events and select a refresh rate from the plurality of refresh rates in response to a monitoring of a current state/scenario;
• and
• a driving device, coupled between the processor and the display panel, controlled by the processor to refresh the display panel with the selected refresh rate.

An electronic device capable of displaying, having capability of switching a refresh rate for refreshing a display panel, comprising:

• a display panel, capable of display frames;
• a processor, configured to dynamically adjust a refresh rate for refreshing the panel when a power-related triggering event occurs;
• and
• a driving device, coupled between the processor and the display panel, controlled by the processor to refresh the display panel with the adjusted refresh rate.

A processor for use in an electronic device capable of displaying, having capability of switching a refresh rate for refreshing a display panel, comprising:

• an image stream consumer, configured to receive an input image stream and output an output image stream;
• a refresh rate selection controller, configured to select a refresh rate from a plurality of refresh rates in response to different triggering events, the different trigger events including at least one of a low power event, a multimedia event, a touch event, and a frame rate monitoring/limitation event for the input image stream;
• and
• a display controller, configured to receive the output image stream from the image stream consumer and transmit image data in the output image stream to a driving device, and in response to the selection by the refresh rate selection controller, control the driving device to refresh the display panel with the selected refresh rate.
