Touch-Triggered Screen Refresh Rate Control for Lower Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in balancing finger track responsiveness and power consumption in terminal devices, particularly in scenarios like battle games and live streaming flash sales, where high screen refresh rates lead to excessive power consumption.
Innovation Solution
A method and device that dynamically adjust the screen refresh rate based on user interactions, increasing it only when specific touch areas are engaged and reducing it otherwise, to maintain responsiveness while conserving power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the screen refresh rate is increased to improve finger track responsiveness, then the screen response speed and user experience are improved, but the power consumption of the terminal device increases excessively
Solution Approach 1:
The patent implements dynamic adjustment of screen refresh rate based on real-time detection of touch operations. The refresh rate changes from a baseline value to a higher target value when touch operations are detected, and returns to baseline when no touch operations are present. This dynamic adaptation resolves the contradiction by providing high refresh rates only when needed for responsiveness, rather than maintaining high refresh rates continuously which would cause excessive power consumption.
Solution Approach 2:
The patent changes the screen refresh rate parameter from a static high value to a dynamically adjustable value. By detecting touch operations and adjusting the refresh rate parameter between different levels (baseline and target), the system achieves fast screen response when users interact with the device while consuming less power during non-interactive periods. This parameter adjustment strategy directly addresses the trade-off between response speed and power consumption.
2Reliability
If the screen refresh rate is maintained at a high level continuously, then the finger track remains responsive, but the battery runtime decreases
Solution Approach 1:
The patent implements periodic detection of touch operations and periodic adjustment of the screen refresh rate. Instead of maintaining a constantly high refresh rate, the system periodically checks for user interactions and adjusts the refresh rate accordingly. This periodic action ensures finger track responsiveness is maintained during user interactions while allowing the system to conserve battery power during non-interactive periods, thus extending battery runtime.
Solution Approach 2:
The system dynamically adjusts the screen refresh rate based on the presence or absence of touch operations. When touch operations are detected, the refresh rate increases to maintain responsive finger track. When no touch operations are detected for a specified duration, the refresh rate decreases to conserve battery power. This dynamic behavior resolves the contradiction between maintaining reliable responsiveness and extending battery runtime.
3Ease of operation
If the screen refresh rate is increased to provide smoother game picture and quicker screen response, then the user experience in battle games is improved, but the power consumption becomes excessively high
Solution Approach 1:
The patent applies different screen refresh rates to different operational contexts. When touch operations are detected (indicating active user interaction such as gaming), the system applies a high target refresh rate to provide smooth picture and quick response. When no touch operations are detected, the system applies a lower baseline refresh rate to reduce power consumption. This local differentiation of quality based on operational context resolves the contradiction between user experience and power consumption.
Solution Approach 2:
The system dynamically adapts the screen refresh rate to match the operational context. By detecting touch operations and adjusting the refresh rate accordingly, the system provides high-quality visual performance during interactive activities like gaming while consuming less power during non-interactive periods. This dynamic adaptation maintains excellent user experience when needed while avoiding excessive power consumption.

AI summary
This application provides a screen display method and a terminal device, which can strike a balance between finger track and power consumption of the terminal device, and is flexibly applicable to various application scenarios, so as to improve user experience. The method includes: detecting a first touch operation of a user on a first screen of an application; displaying a second screen at a screen refresh rate equal to a frame rate of the application in response to the first touch operation, and determining whether the second screen is a target screen; when the second screen is the target screen, determining whether a second touch operation of the user on the second screen is detected; when the second touch operation is detected, determining whether a touch area corresponding to the second touch operation is a target area; when the touch area corresponding to the second touch operation is the target area, determining a target screen refresh rate based on the frame rate of the application; and displaying the second screen at the target screen refresh rate in response to the second touch operation.
