Flexible Display Sliding Control Using Force Touch Intent Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with flexible displays face issues in accurately detecting user intent for sliding motions, leading to unintended malfunctions, as they often rely on general touch inputs rather than differentiated touch types like force touch inputs.
Innovation Solution
The electronic device includes a flexible display with a sliding mechanism controlled by a driving motor, which detects force touch inputs to identify a sliding condition and adjusts the display area accordingly, using processors and memory to execute instructions for precise sliding motions based on touch input analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the device uses general touch input detection, then the device structure remains simple, but the device cannot accurately distinguish user intent leading to unintended malfunctions
Solution Approach 1:
The patent applies parameter changes by detecting multiple touch parameters (pressure, contact area, touch duration) rather than just basic touch presence. The processor analyzes variations in these parameters over time to distinguish between intentional sliding commands and accidental touches, thereby improving detection accuracy without requiring additional hardware sensors
Solution Approach 2:
The system implements dynamics by continuously monitoring touch input parameters over time and adapting its response based on the evolution of the touch pattern. The processor evaluates whether touch parameters meet sliding conditions at multiple time points, allowing the system to dynamically distinguish between sustained intentional touches and transient accidental contacts
2Adaptability or versatility
If the device enables sliding motion functionality, then the display area can be extended, but the device may malfunction by performing unintended sliding motions
Solution Approach 1:
The patent implements feedback by continuously monitoring touch input parameters and using this information to control the sliding motion. The processor evaluates whether touch parameters satisfy sliding conditions before activating the motor, and can adjust or cancel sliding motion based on ongoing touch pattern analysis, ensuring reliable operation
Solution Approach 2:
The system applies preliminary action by pre-defining sliding conditions that must be satisfied before sliding motion is activated. The processor evaluates touch parameters against these predetermined conditions (such as minimum pressure thresholds, contact area ratios, and touch duration requirements) before initiating the sliding sequence, preventing unintended activation
3Measurement precision
If the device requires force touch input for sliding, then user intent can be accurately identified, but the device complexity increases due to additional detection requirements
Solution Approach 1:
The patent applies universality by using the existing display touchscreen to perform multiple functions: both basic touch input detection and force touch detection. The processor analyzes the same touch signal for multiple parameters (pressure, contact area, duration) to serve both general navigation and sliding motion control, eliminating the need for separate force-sensitive hardware

AI summary
An electronic device is provided. The electronic device includes a first housing, a second housing slidably coupled to the first housing, a flexible display of which a display area varies based on a sliding motion of the second housing, a drive motor configured to control the sliding motion of the second housing, memory storing instructions, and at least one processor operatively coupled to the flexible display, the drive motor, and the memory. The instructions, when executed by the at least one processor individually or collectively, cause the electronic device to detect a touch input event for an object displayed through the flexible display, individually or collectively, cause the electronic device, identify whether the touch input event satisfies a sliding condition, when the touch input event satisfies the sliding condition, output sliding content corresponding to the object, and drive the drive motor so that the display area of the flexible display varies on the basis of the sliding content.
