Flexible Display Area Control via Gesture Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices that can be folded and rolled lack effective methods for dynamically controlling their display area, leading to user inconvenience when deformed, as the display area is typically fixed, limiting their usability in various forms.
Innovation Solution
A method and apparatus that utilize input signals from a user's touch to determine whether the signals are for controlling the display area by analyzing the time and similarity of gradients of line elements, allowing the display area to be dynamically set and divided into discrete regions based on closed loops and edge portions, enabling flexible reconfiguration of the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display area is fixed, then the device structure is simple, but the usability is inconvenient when deformed
Solution Approach 1:
The patent implements dynamic display area control by detecting user touch gestures on the flexible display device and automatically adjusting the display region boundaries. The system transitions from a fixed display area to a dynamically adaptable one that responds to user input, allowing the display area to be expanded, contracted, or repositioned based on gesture recognition algorithms.
Solution Approach 2:
The display area adjustment system operates autonomously by detecting user gestures and automatically reconfiguring the display region without requiring manual intervention or complex external controls. The system serves itself by using the display surface as both the interaction interface and the controlled element, eliminating the need for separate control mechanisms.
2Adaptability or versatility
If the display area is fixed, then the control system is simple, but the adaptability to various forms is limited
Solution Approach 1:
The display area is transformed from a static configuration to a dynamic one that can adapt to various deformed forms of the flexible device. The system continuously monitors the device shape and adjusts the display region boundaries accordingly, enabling the display to maintain usability whether the device is flat, bent, folded, or rolled into spiral structures.
Solution Approach 2:
The gesture-based control system serves multiple functions: it detects user intent, determines desired display area configurations, and executes the adjustment commands. This multi-functional approach allows a single control mechanism to handle various display reconfiguration scenarios, enhancing adaptability without proportionally increasing system complexity.
3Adaptability or versatility
If gesture recognition is used to control display area, then the adaptability is improved, but the signal detection complexity increases
Solution Approach 1:
The patent replaces complex mechanical or hardware-based display control mechanisms with a software-based gesture recognition system. By utilizing the touch-sensitive properties of the display surface and implementing algorithmic gesture detection, the system achieves sophisticated display area control without requiring additional mechanical components, sensors, or physical controls.
Solution Approach 2:
The gesture recognition system acts as an intermediary between the user and the display area control function. Instead of directly manipulating display parameters, users perform natural gestures on the display surface, and the system translates these gestures into appropriate display reconfiguration commands, simplifying the user interface while maintaining control precision.

AI summary
An apparatus for controlling a display area of a flexible display device includes a display area and a display unit to which a touch is input. A method of using the apparatus includes obtaining a first input signal, a second input signal, a third input signal, and a fourth input signal that are input to the display unit by a user's touch and respectively correspond to a first line element, a second line element, a third line element, and a fourth line element on the display unit, determining whether the first to fourth input signals are for controlling the display area, and setting the display area based on a closed loop composed of the obtained first to fourth line elements and first and second edge portions of the display unit if it is determined that the first to fourth input signals are for controlling the display area.
