Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-screen devices struggle to accurately and timely control which screen to turn on or off based on changing application scenarios, leading to inefficiencies and reduced user experience.
Innovation Solution
Implementing a high-power sensor and a low-power sensor in electronic devices to detect posture and screen-on triggers, respectively, allowing the device to quickly determine and control which screen to turn on based on user interactions and device posture, with the high-power sensor being enabled only after a screen-on trigger is received.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the high-power sensor is continuously enabled to detect device posture, then the screen can be accurately controlled based on application scenarios, but the power consumption increases
Solution Approach 1:
The low-power sensor performs preliminary detection of screen-on trigger signals before the high-power sensor is activated. This preliminary action allows the system to prepare for accurate screen control while minimizing power consumption during idle periods.
Solution Approach 2:
The system dynamically switches between sensor states based on operational needs. The high-power sensor is enabled only when triggered by the low-power sensor, creating a dynamic power management strategy that adapts to real-time usage patterns.
2Use of energy by moving object
If the high-power sensor is disabled to reduce power consumption, then the screen response time increases
Solution Approach 1:
The low-power sensor continuously monitors for screen-on trigger signals in advance, so when a trigger is detected, the system can immediately activate the high-power sensor and subsequent screen control processes, minimizing response time while maintaining low power consumption during idle states.
Solution Approach 2:
Upon detecting a trigger signal, the system rapidly transitions from the low-power state to the high-power state, rushing through the activation process to minimize the time delay before the screen responds, thereby reducing perceived response time.

AI summary
This solution relates to the field of terminal artificial intelligence (artificial intelligence, AI) technologies, and discloses a screen-on control method and an electronic device. The electronic device related to this application includes a first screen and a second screen. A high-power sensor of the electronic device is in a disabled state, and a low-power sensor of the electronic device is in an enabled state. The electronic device includes a foldable device. Based on this, after the electronic device receives a screen-on trigger signal from the low-power sensor or a processor of the electronic device, the electronic device may determine a to-be-lit-up first target screen based on the screen-on trigger signal, and then control the first target screen to be lit up. It can be learned that, in the technical solution disclosed in this application, when the high-power sensor is in a disabled state, a screen can be controlled to be lit up in response to the screen-on trigger signal, so that user experience can be improved.
