Context-Aware Display Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information handling devices automatically engage low power mode for displays after inactivity, failing to distinguish between tasks requiring user input and those that do not, leading to unnecessary screen shutdowns.
Innovation Solution
A method that analyzes context data associated with displayed content to determine the appropriate power setting for the display, allowing it to remain powered in situations where user input is not required, such as viewing recipes or presentations, by mapping context data to predetermined display settings.

Engineering Contradiction Analysis
1Use of energy by moving object
If the display automatically enables low power mode after a period of inactivity, then power consumption is reduced, but the display may shut down unnecessarily during tasks that do not require user input
Solution Approach 1:
The system monitors user interactions and task context to dynamically adjust display power modes. By implementing feedback mechanisms that track whether the user is actively engaged with the device, the system can intelligently determine when to maintain display power versus when to activate low power mode, preventing unnecessary shutdowns during passive tasks while still conserving energy during actual inactivity.
Solution Approach 2:
The display power mode transitions from a static, fixed timeout-based system to a dynamic, context-aware system. The power management adapts in real-time based on the detected task type and user engagement level, allowing the display to remain powered during tasks like reading or viewing presentations while automatically entering low power mode during genuine inactivity periods.
2Reliability
If the display remains powered on to prevent unnecessary shutdowns, then display availability is maintained, but power consumption increases
Solution Approach 1:
The system changes the parameter of display power state based on detected context. By analyzing task type and user interaction patterns, the system dynamically adjusts the power consumption parameter, maintaining full power during active use and transitioning to low power mode during appropriate intervals, thus optimizing the balance between availability and energy usage.
Solution Approach 2:
The power management applies different quality states to different usage scenarios. Instead of a uniform power policy, the system implements context-specific power levels tailored to the detected task type, allowing the display to operate at appropriate power levels for each specific use case rather than applying a single global setting.

AI summary
One aspect provides a method, including: displaying, on a display device, display data; implementing, using a processor, a first power setting for the display device; accessing, using a processor, context data associated with the display data during use of the first power setting; mapping, using a processor, the context data to a predetermined display context, the predetermined display context being associated with a display setting; and switching, using the processor, the first power setting to the display setting of the display context. Other aspects are described and claimed.
