Presence-Gated Mural Display Activation to Cut Screen Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices like televisions consume high power when displaying artworks or photos for extended periods, leading to increased power consumption.
Innovation Solution
Implement a display method that turns off the screen when not in use and turns it on only when a user enters and stays in a specified region for a certain duration, displaying a mural interface to enhance aesthetics while reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the display is turned on to show paintings or photos, then the aesthetic decoration effect is improved, but the power consumption increases
Solution Approach 1:
The display system dynamically adjusts its state between off and on based on real-time detection of user presence and behavior. The display turns on only when a user enters the first region and remains for the first duration, then turns off after the second duration has elapsed since the user left. This dynamic state change allows the system to provide aesthetic decoration when needed while minimizing power consumption during idle periods.
Solution Approach 2:
The system uses feedback from the detection module to control display state. When the detection module identifies that a user enters the first region and stays for the first duration, it triggers the display to turn on. When the user leaves and the second duration elapses, the feedback signal causes the display to turn off. This feedback mechanism ensures the display responds appropriately to user presence while avoiding unnecessary power consumption.
2Ease of operation
If the display turns on frequently when users pass by, then user experience is improved, but power consumption increases
Solution Approach 1:
The system performs preliminary detection and verification before activating the display. Instead of turning on immediately when a user approaches, the system first detects whether the user enters the first region, then verifies whether the user stays for the first duration, and only after confirming these conditions does it activate the display. This preliminary action filter prevents unnecessary activation and reduces power consumption while still providing good user experience when users are actually present.
Solution Approach 2:
The display system dynamically adjusts its activation threshold based on user behavior patterns. It uses the first duration threshold to determine when a user's presence is sufficient to warrant display activation, and the second duration threshold to determine when to deactivate. This dynamic approach ensures the display is on only when necessary, balancing user experience with power conservation.
3Use of energy by moving object
If the display remains off to save power, then power consumption is reduced, but the aesthetic decoration effect is lost
Solution Approach 1:
The display system dynamically transitions between off and on states based on real-time user presence detection. When no user is detected in the first region for the required duration, the display remains off to conserve power. When a user enters and meets the duration criteria, the display transitions to on state to provide aesthetic decoration. This dynamic adjustment ensures the system achieves both low power consumption and effective decoration as needed.
Solution Approach 2:
The detection module provides continuous feedback about user presence to the display control system. When feedback indicates a user is present and meets the duration criteria, the display turns on to restore aesthetic decoration. When feedback shows the user has left or hasn't stayed long enough, the display remains off to maintain power savings. This feedback loop ensures the system achieves both objectives simultaneously.

AI summary
This application discloses a display method and a related apparatus. A display of an electronic device is off. When the display remains off, it is detected that a user enters a first region. If it is detected that the user stays in the first region for first duration and stays in a second region for the first duration, the display is switched from being off to being on, and a first interface is displayed on the display. The first region includes the second region. After the first interface is displayed on the display, if it is detected that duration for which the user leaves the first region reaches second duration, the display is switched from displaying the first interface to being off. If it is detected that the user stays in the first region for the first duration but does not stay in the second region for the first duration, the display is kept off. In this way, after detecting that the user enters the first region, the electronic device still keeps the display off, and displays a mural interface only after determining that the user stays in the second region for the first duration. This avoids a case that a user action is interfered with because the electronic device frequently turns on a screen when the user passes by, to reduce power consumption.
