Touch Control Region Partitioning for Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with touch control functions consume excessive power due to full screen scanning when users interact with icons, leading to inefficient power saving.
Innovation Solution
The implementation of a control method that partitions the touch region into smaller areas, disabling unused touch functions and limiting scans to the region of active icons, thereby reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If full screen scanning is performed to detect icon clicks, then touch detection coverage is complete, but power consumption increases significantly
Solution Approach 1:
The touch control unit is divided into multiple touch regions, with each region corresponding to one or more icons. Instead of scanning the entire screen, the system only scans the specific touch region where a touch event is detected, significantly reducing power consumption while maintaining complete touch detection coverage.
Solution Approach 2:
Different scanning strategies are applied to different regions of the touch control unit. The system performs detailed scanning only in the local region where a touch event occurs, rather than uniformly scanning the entire screen, optimizing the balance between detection accuracy and power consumption.
2Use of energy by moving object
If the touch function is disabled for inactive regions, then power consumption is reduced, but the ability to detect touches in those regions is lost
Solution Approach 1:
The touch function of different regions is dynamically adjusted based on activity status. When a touch event is detected in a region, that region's scan function is activated; when no touches occur, the scan function is disabled. This dynamic switching reduces power consumption while ensuring touch detection capability is available when needed.
Solution Approach 2:
Instead of continuous scanning of all regions, the system performs periodic scanning only in regions where touch events have been detected. This periodic activation of scan functions reduces power consumption while maintaining the ability to detect touches in all regions over time.

AI summary
This application discloses a control method of electronic apparatus and an electronic apparatus, wherein the electronic apparatus includes a touch control unit, on which there is at least one operating icon. The control method comprises determining a first touch region corresponding to the at least one operating icon, wherein, an area of the first touch region is less than the area of the touch control unit; determining a second touch region on the touch control unit according to the first touch region, wherein, the second touch region is a region other than the first touch region on the touch control unit; generating a control instruction for making touch function of the second touch region to be in a disable status; and executing the control instruction to make the touch function of the second touch region to be in the disable status.
