  • Publication number: 20250138676
    Abstract: An electronic device including a display panel and a CPU is provided. The display panel updates displayed images at a refresh rate. The CPU implements a latency monitor, a system resource controller, a display controller, and an application. The latency monitor collects time information related to touch latency. The touch latency is the duration between the time point at which the display panel detects a touch event and the time point at which the display panel displays an image generated by the application in response to said touch event. The display controller informs the system resource controller of the refresh rate. The system resource controller adjusts the resource allocation of the electronic device to cause the touch latency to be lower than a threshold, according to the time information and the refresh rate.
