Multi-Screen Touch Control for Independent Screen-Off Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to efficiently manage power consumption on multi-screen devices by uniformly turning off screens after a set duration, leading to unnecessary resource consumption and reduced system performance.
Innovation Solution
A method and device that detect touch operations on multiple screens, record touch times, and independently control each screen to enter a power-saving state based on individual interaction durations, releasing resources accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If uniform automatic screen-off time is applied across all screens, then screen-off control is simple, but power consumption increases and resource occupation is unnecessary
Solution Approach 1:
The patent divides the screen-off control into individual screen-level decisions rather than a uniform system-wide approach. Each touch screen independently tracks its own touch time and determines when to enter screen-off state, allowing selective power management for each screen based on actual usage patterns.
Solution Approach 2:
Each touch screen autonomously monitors its own interaction time and independently decides when to transition to screen-off state. The system removes the need for centralized control and allows each screen to self-manage its power state based on local usage conditions.
2Device complexity
If uniform automatic screen-off time is applied across all screens, then control logic is simple, but resource occupation increases
Solution Approach 1:
The control logic is segmented at the individual screen level, with each touch screen maintaining its own touch time record and screen-off determination. This allows the system to release resources from inactive screens while maintaining simple, localized control logic that doesn't require complex centralized management.
Solution Approach 2:
The system releases resources from touch screens that have met the screen-off condition by discarding their occupied state. When a screen enters screen-off state, its associated resources are released back to the system, optimizing resource utilization without requiring complex tracking mechanisms.
3Reliability
If touch time on one screen is used as interaction time for all screens, then system performance is maintained, but unnecessary function consumption occurs
Solution Approach 1:
The patent segments the interaction time tracking by individual screen, so that touch time on one screen does not automatically apply to other screens. Each screen maintains its own independent timer and screen-off determination logic, preventing unnecessary function consumption on inactive screens while preserving system performance through accurate per-screen usage tracking.

AI summary
The present invention relates to a method and device for controlling a screen, and a storage medium. A touch operation applied to one of N touch screens in a screen-on state is detected (101). Touch time of the touch operation is recorded(101). The N is a positive integer greater than or equal to 2. It is determined(102), based on a touch time of one last touch operation detected on an n-th touch screen of the N touch screens, whether a duration in which no touch operation has been detected on the n-th touch screen reaches a preset duration. The n is a positive integer less than or equal to the N. When the duration in which no touch operation has been detected on the n-th touch screen reaches the preset duration, the n-th touch screen is controlled (103) to enter a screen-off state.
