Solution Overview

Problem

Existing screen wake-up technologies for multi-screen terminals fail to adaptively wake up a specific user-designated screen, leading to unnecessary power consumption and potential privacy breaches by activating unintended screens.

Innovation Solution

A method to determine and wake up a user-designated screen by detecting touch or back tapping operations, utilizing sensors and face recognition to confirm the intended screen, and maintaining other screens in a non-wake-up state.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If all screens are woken up when a wake-up operation is detected, then the user experience is improved by ensuring the correct screen is active, but power consumption increases and privacy may be compromised

Engineering Contradiction:
Improvescreen wake-up accuracyVSAvoidpower consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent segments the wake-up control by screen, allowing independent wake-up state management for each screen based on user designation. When a wake-up operation is detected, only the designated screen (e.g., first screen) is woken up while other screens remain in sleep state, avoiding unnecessary power consumption of non-designated screens.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by differentiating wake-up behavior for different screens. The designated screen receives the wake-up activation while other screens maintain their sleep state, creating localized wake-up effect precisely where needed rather than global activation of all screens.

Inventive Principle:
Principle #3Local quality

2Ease of operation

If all screens are woken up when a wake-up operation is detected, then the user experience is improved by ensuring the correct screen is active, but user privacy may be breached by activating unintended screens

Engineering Contradiction:
Improvescreen wake-up accuracyVSAvoidprivacy breach
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent segments the wake-up control by screen, allowing independent wake-up state management for each screen based on user designation. When a wake-up operation is detected, only the designated screen (e.g., first screen) is woken up while other screens remain in sleep state, avoiding unnecessary power consumption of non-designated screens.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by differentiating wake-up behavior for different screens. The designated screen receives the wake-up activation while other screens maintain their sleep state, creating localized wake-up effect precisely where needed rather than global activation of all screens.

Inventive Principle:
Principle #3Local quality

3Use of energy by moving object

If a single screen is selectively woken up in multi-screen terminals, then power consumption is reduced, but the complexity of determining which screen to wake up increases

Engineering Contradiction:
Improvepower consumptionVSAvoidscreen determination logic
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-designating which screen should be woken up before the wake-up operation occurs. The user can set a default wake-up screen in advance, so when a wake-up operation is detected, the system directly activates the pre-designated screen without complex real-time determination logic.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent applies self-service by allowing the system to automatically determine which screen to wake up based on pre-configured user preferences or context information. The system autonomously makes the decision without requiring complex user interaction or complex processing logic at wake-up moment.

Inventive Principle:
Principle #25Self-service

AI summary

The present disclosure relates to a screen wake-up method, a screen wake-up apparatus and a storage medium. The screen wake-up method includes: in response to determining a user performing a screen wake-up operation on the terminal, determining a first screen among the plurality of different screens; and waking up the first screen while keeping other screens except for the first screen among the plurality of different screens in a non-wake-up state. Through the present disclosure, it is possible to determine and wake up a user-designated screen among the plurality of different screens of the terminal.
