Rollable Screen Call Handling Through Automatic Retraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rollable screen smartphones face challenges in user experience when receiving calls due to difficulty in holding the device with one hand and potential accidental triggers during screen retraction, especially when the screen is extended.
Innovation Solution
The method automatically retracts the extendable screen to a target size before outputting call prompts, allowing one-handed operation and preventing accidental triggers by controlling the screen speed and scenario conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the rollable screen is kept in extended state to provide large display area, then the display area is increased, but the device becomes difficult to hold with one hand and microphone alignment becomes difficult during calls
Solution Approach 1:
The patent applies dynamics by making the screen size changeable based on usage scenario. The screen transitions from extended state during media playback to retracted state during calls, allowing the device to adapt its physical configuration dynamically to meet different operational needs.
Solution Approach 2:
The system performs preliminary action by detecting the call scenario in advance and automatically retracting the screen before the user needs to hold the device. This automated preliminary retraction prevents the user from having to manually operate the screen during call scenarios.
2Ease of operation
If manual operation is required to retract the screen before answering a call, then the screen can be retracted, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The system applies self-service by automatically detecting the call scenario and triggering screen retraction without requiring manual user input. The device serves itself by autonomously transitioning the screen from extended to retracted state based on scenario detection.
Solution Approach 2:
The system performs preliminary action by automatically retracting the screen as soon as a call scenario is detected, before the user needs to answer the call. This eliminates the time delay associated with manual retraction operations.
3Reliability
If manual button pressing is used to retract the screen, then the screen can be retracted, but accidental triggers may occur affecting user experience
Solution Approach 1:
The system applies feedback by using scenario detection to determine when screen retraction is appropriate. The detection mechanism provides feedback about the current usage context (call vs. media playback), and based on this feedback, the system automatically controls screen retraction only when appropriate, preventing accidental triggers.
Solution Approach 2:
The device performs self-service by autonomously detecting scenarios and controlling screen retraction without requiring manual button presses. This eliminates the risk of accidental triggers while maintaining reliable screen retraction functionality.

AI summary
This application discloses a control method and apparatus applied to an electronic device, an electronic device, and a readable storage medium, and pertains to the field of electronic devices. In embodiments of this application, in a case that a call request is received, instead of displaying a call request prompt interface, an extension state of an extendable screen is determined first; and if the extendable screen is in extended state, the extendable screen is controlled to retract to a target size, and prompt information of the call request is output for a user to answer the call after the screen is retracted.
