Foldable Terminal Display Control for Hold-Aware Pop-Up Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminals with foldable screens face inconvenience due to large screen sizes when notifications or pop-ups are displayed, and existing touch sensors inaccurately detect held positions, leading to poor user experience.
Innovation Solution
A display control method that utilizes touch data from a second screen and sensor data from a biological detection sensor on the folded side of the terminal to determine the held position, allowing the function display interface to be displayed in the appropriate area of the first screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a message pop-up notification is displayed on a large unfolded screen, then the display area is sufficient, but it brings great inconvenience to the user
Solution Approach 1:
The patent applies local quality by displaying the notification interface only in the specific region corresponding to the held position rather than across the entire large screen. This allows the notification to be localized in the user's hand area, making it convenient to operate while utilizing the large display area of the unfolded screen.
Solution Approach 2:
The patent implements dynamics by dynamically adjusting the notification display position based on the real-time held position detection. The system continuously monitors touch data and sensor data to determine where the user is holding the device, and automatically positions the notification in the corresponding screen area, making the display adaptive to user interaction.
2Device complexity
If touch sensors are used to detect held position, then the detection mechanism is simple, but the detection accuracy is insufficient
Solution Approach 1:
The patent merges multiple detection mechanisms - touch sensors on the screen and additional sensors on the device body - to detect held position. By combining data from both touch sensor locations and body-mounted sensors, the system achieves more accurate held position detection while maintaining relatively simple individual sensor implementations.
Solution Approach 2:
The patent introduces sensor data as an intermediary to enhance touch sensor detection. The sensors arranged on the device body detect holding characteristics and provide supplementary information that helps determine the held position more accurately, acting as intermediaries that bridge the gap between simple touch detection and precise position measurement.

AI summary
A display control method is applied to a terminal, and includes: in response to that a first screen represented by the terminal in an unfolded state is lit, detecting whether a function display interface to be displayed is triggered to be displayed in the first screen, in which a display area of the function display interface is smaller than a display area of the first screen; in response to detecting that the function display interface to be displayed is triggered, acquiring touch data detected on a second screen and sensor data detected by a biological detection sensor; and determining a held position of the terminal according to the touch data and the sensor data, and controlling the function display interface to be displayed in a screen area of the first screen corresponding to the held position.
