A processor for use in an electronic device capable of displaying, having capability of switching a refresh rate for refreshing a display panel. The processor can dynamically transition between different states/scenarios in response to different triggering events. The processor can include an image stream consumer, configured to receive an input image stream and outputting an output image stream; a refresh rate selection controller, configured to select a refresh rate from a plurality of refresh rates in response to a monitoring of a current state/scenario; 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 a display panel with the selected refresh rate.

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

A processor for use in an electronic device is provided. The electronic device is capable of displaying and the processor has capability of switching a refresh rate for refreshing a display panel of the display device. The processor comprises: a refresh rate selection controller and a display controller. The refresh rate selection controller is configured to dynamically select one from a plurality refresh rates. The display controller is configured to control a driving device to refresh the display panel with the selected refresh rate and determine whether to adjust a data transmission rate over an interface between the processor and the driving device according to the selected refresh rate.

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

A video frame transmitting system transmitting at least one output video frame to a display based on content of at least one input video frame. The video frame transmitting system has a display driver receiving an active input video frame and outputting the active input video frame as the output video frame to the display. The video frame transmitting system comprises: an application processor, receiving the input video frame, for determining the input video frame as the active input video frame if the content of the input video frame is different from content of a previous input video frame, and for determining the input video frame as a skip input video frame if the content of the input video frame is the same as the content of the previous input video frame. The application processor outputs the active input video frame to the display driver but does not output the skip input video frame.
