Active Display Power States for Fast Resume and Lower Energy Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices with active display systems consume excessive power due to components remaining in an active state during periods of inactivity, leading to inefficient power management.
Innovation Solution
A configuration that detects inactivity based on gesture input frequency, transitioning the device into an idle state and further into a regularized suspended state, reducing power consumption by deactivating non-essential components while maintaining a persistent display.

Engineering Contradiction Analysis
1Speed
If components remain in an active state during periods of inactivity, then the device can quickly resume operation when needed, but power consumption increases significantly
Solution Approach 1:
The system dynamically adjusts the operational state of display components based on detected user activity levels. During active use, components operate at full performance; during inactivity periods, components transition to lower power states while maintaining the ability to quickly resume when user interaction is detected again.
Solution Approach 2:
The system implements periodic monitoring of user interaction with the display and adjusts component states accordingly. Power consumption is reduced during detected inactivity periods, and components are periodically reactivated when user interaction resumes, creating a rhythmic pattern of high and low power states that optimizes overall energy efficiency.
2Use of energy by moving object
If components are deactivated during inactivity, then power consumption is reduced, but the device response time increases when user interaction resumes
Solution Approach 1:
The system performs preliminary actions by maintaining certain display components in a partially active or standby state during inactivity periods, rather than fully deactivating them. This preliminary maintenance of operational readiness allows for faster resumption of full functionality when user interaction occurs, while still achieving significant power savings compared to keeping all components fully active.
3Reliability
If all components remain active, then the display system can maintain full functionality and responsiveness, but battery life is significantly reduced
Solution Approach 1:
The system segments the display components into different operational groups that can be independently controlled. During inactivity periods, non-essential components are deactivated or placed in low-power modes while essential components remain operational. This segmentation allows the system to maintain core display functionality and responsiveness while dramatically reducing overall power consumption to extend battery life.

AI summary
One embodiment of a disclosed system, method, and computer readable storage medium which includes an algorithm for regulating power to electronic components of a device. In an active state, the system detects a period of inactivity based on a frequency of gesture inputs to the contact-sensitive surface of the device. In response to detecting the period of inactivity, the device transitions into an idle state with reduced power consumption by electronic components of the device. The device records an amount of time that the device has spent in the idle state transitions into a regularized suspend state where power consumption by electronic components of the device is reduced from the consumption in the idle state to detect one or more activation trigger conditions. In the regularized suspended state, the device presents a persistent display comprising a graphic generated in response to a most recent set of user inputs the device.
