Flexible Display Region Control for Wearable Power Savings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices with rotating display screens require manual adjustment to bring the screen into view, leading to inconvenience and increased power consumption as the entire screen is displayed even when not in sight.
Innovation Solution
A mobile terminal with a display screen divided into regions, using sensors to detect offset positions and adjust the display region accordingly, reducing power consumption by only displaying content in the relevant region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire display screen is always activated to show information, then the user can always view content, but power consumption increases significantly
Solution Approach 1:
The display screen is divided into multiple independent display regions that can be selectively activated. Only the display region corresponding to the current offset position is activated to show information, while other regions remain inactive. This segmentation allows the system to maintain information display availability in the visible region while significantly reducing overall power consumption by keeping other regions dormant.
2Use of energy by moving object
If the wristband requires manual rotation to bring the display screen into view, then the entire screen can be displayed, but user convenience deteriorates
Solution Approach 1:
The system automatically detects the offset position of the display screen using sensors and autonomously determines which display region should be active without requiring user intervention. The processor automatically adjusts the display configuration based on the detected position, providing self-service functionality that eliminates the need for manual rotation while optimizing power consumption based on actual viewing conditions.
3Use of energy by moving object
If the display screen is divided into multiple regions and only the relevant region is activated, then power consumption is reduced, but the system complexity increases
Solution Approach 1:
The offset position detection mechanism serves multiple functions: it detects the display screen's positional deviation, determines the appropriate display region to activate, and provides the basis for content rendering decisions. This multi-functionality reduces the need for separate control mechanisms for each display region, thereby managing system complexity while enabling selective region activation and power savings.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Automatically adjusts the display region based on the terminal's position, reducing power consumption and improving battery life by only activating the necessary screen area.
Implementation Method 1
the body is also provided with a level sensor, the level sensor is configured to measure a target angle value of the flexible display screen deviating from a preset reference position
Data Source
AI summary
A screen display method and apparatus and a mobile terminal are provided. The method includes: acquiring target offset position information of the display screen of the mobile terminal deviating from a preset reference position; searching for target display region information corresponding to the target offset position information from a preset database, the preset database comprising at least one set of offset position information and display region information corresponding to each set of the offset position information; and displaying content to be displayed by the mobile terminal in a display region indicated by the target display region information.
