Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display device is transformed into a three-dimensional shape, then the adaptability and versatility of the display device are improved, but the difficulty of controlling the imaging area increases
Solution Approach 1:
The system uses the display device itself as the input device by detecting touch inputs directly on the flexible display surface. The flexible display device serves both as the display medium and the input sensing medium, eliminating the need for separate control interfaces and simplifying the overall control architecture while maintaining adaptability to three-dimensional shapes
Solution Approach 2:
The patent extends the traditional flat two-dimensional touch input model to three-dimensional curved surfaces by mapping touch coordinates through mathematical transformations. The system handles coordinates on curved surfaces by projecting them onto a flat reference plane, performing touch processing, and then mapping back to the three-dimensional display surface, thus enabling standard control methods to work on flexible three-dimensional displays
2Device complexity
If existing flat display control methods are used on transformed flexible display devices, then the device complexity is reduced, but the measurement precision and control accuracy of the imaging area deteriorate
Solution Approach 1:
The system dynamically adjusts control parameters based on the three-dimensional shape of the flexible display device. By detecting the current shape configuration and calculating corresponding coordinate transformation parameters, the system adapts the touch input mapping to match the actual display geometry, ensuring precise imaging area control regardless of the device's transformed shape
Solution Approach 2:
The patent replaces complex mechanical control systems with mathematical coordinate transformation algorithms. Instead of using separate mechanical actuators or physical controls for each possible three-dimensional shape, the system uses computational geometry to map touch inputs across different shapes, significantly simplifying the control architecture while maintaining precision

AI summary
Provided are a method and apparatus for controlling an imaging area of a flexible display device. A method of controlling an imaging area in a display area of a flexible display device including a display unit for receiving a touch, and a display area overlapping the display unit and for displaying an image includes obtaining at least two input signals input to the display unit in response to a continuous touch in the form of a closed loop, setting an internal area of the closed loop as an imaging area based on the obtained at least two input signals, and controlling the image displayed on the display area to be moved and displayed onto the set imaging area. An area for displaying an image may be controlled appropriately for the shape of a flexible display device by using an input signal generated by a user's touch.
