Touch Panel Sampling Rate Switching for Power and Gesture Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch panel sampling rates in electronic devices cause high power consumption when set too high and poor gesture-following performance when set too low, leading to inconsistent user experience across different applications.
Innovation Solution
Adjust the touch panel sampling rate based on user input and application requirements, considering factors such as application type and scenario changes, to optimize power consumption and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the touch panel driver always scans the touch input at a relatively high TP sampling rate, then the gesture-following performance is improved, but the power consumption increases
Solution Approach 1:
The patent applies dynamics by making the TP sampling rate adjustable rather than fixed. The system dynamically changes the sampling rate based on the running application's requirements and user preferences, allowing the touch panel driver to scan at high rates when performance is needed and low rates when power saving is prioritized, thus resolving the contradiction between gesture-following performance and power consumption
Solution Approach 2:
The patent changes the parameter of TP sampling rate from a constant value to a variable that can be adjusted according to different scenarios. By modifying this parameter based on application type (e.g., games requiring high sampling rates vs. communication apps tolerating lower rates) and user settings, the system optimizes both performance and power consumption
2Use of energy by moving object
If the touch panel driver always scans the touch input at a relatively low TP sampling rate, then the power consumption is reduced, but the gesture-following performance deteriorates
Solution Approach 1:
The system dynamically adjusts the sampling rate based on real-time conditions rather than using a fixed low rate. When power saving is needed, it lowers the sampling rate, but when performance requirements arise (detected through application type or user preference), it increases the rate accordingly
Solution Approach 2:
The TP sampling rate parameter is changed from a static low value to a dynamic value that adapts to different applications and user preferences, ensuring power consumption is minimized without permanently sacrificing gesture-following performance
3Device complexity
If a fixed TP sampling rate is used for all applications, then the system complexity is reduced, but the user experience consistency across different applications deteriorates
Solution Approach 1:
The patent applies local quality by customizing the TP sampling rate for different applications based on their specific needs. Instead of a uniform sampling rate for all apps, the system tailors the sampling rate to each application's requirements (e.g., higher for games, lower for communication apps), improving user experience consistency across different usage scenarios
Solution Approach 2:
The system achieves universality by creating a multi-functional sampling rate adjustment mechanism that serves multiple purposes: optimizing performance for different application types, respecting user preferences, and adapting to various usage scenarios, all through a single flexible control system

AI summary
Embodiments of this application provide a method for adjusting a touch panel (TP) sampling rate and an electronic device and relate to the field of terminal technologies. The method is applicable to an electronic device, where the electronic device includes a TP and a first application is installed on the electronic device. The method may include: scanning a touch operation on the TP by adopting a first sampling rate under a first application scenario of the first application; and under the condition that the application scenario of the first application is switched from a first application scenario to a second application scenario, scanning the touch operation on the TP by adopting a second sampling rate, wherein the first application scenario is different from the second application scenario, and the first sampling rate is different from the second sampling rate.
