Embodiment Construction

[0016] Certain terms are used throughout this patent specification and claims to refer to particular components. It should be understood by those skilled in the art that hardware manufacturers may refer to the same component by different terms. The patent specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. "Includes" or "comprising" mentioned throughout the specification and claims are open-ended terms, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described in the text that a first device is coupled to a second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means. . ...

Abstract

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 electronic device. The processor includes: 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.

Description

technical field [0001] The present invention relates to refresh rate (refresh rate) switching, and in particular to a processor and an electronic device that can dynamically switch the refresh rate of a display panel and adjust the data transfer rate on an interface used to connect to a drive device that drives the display panel . The invention also relates to a method for switching the refresh rate of a display panel in an electronic device. Background technique [0002] The display device refreshes the displayed image periodically. In a general display device, a driving device, such as a display driver integrated chip (DDIC), receives image data of an image to be displayed from a graphics processing unit (graphic processing unit, GPU) or a display-related circuit controlling the display device. And, according to the received image data, the timing controller (timing controller) in the driving device instructs and controls the source driver and the gate driver in the driv...
