Solution Overview
Problem
Foldable display devices face impairment in visual information display due to deformation caused by folding, leading to distortion, blocking, compression, pinching, and compromised viewing angles, which existing technologies fail to adequately address.
Innovation Solution
A display system that includes a foldable display unit and a fold detection system, where load cells or other sensors generate fold detection signals to adjust the display format mathematically, compensating for distortions by altering the configuration, size, position, and brightness of visual information to maintain clear viewing across folded areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display unit is folded to enable portability and flexible form factors, then the device becomes more portable and adaptable, but the visual information display is impaired due to deformation, distortion, and compromised viewing angles
Solution Approach 1:
The system performs preliminary detection of the fold state using load cells before displaying visual information. By detecting the fold condition in advance and pre-calculating the appropriate display format adjustments, the system compensates for distortion effects before they occur, ensuring maintained display quality despite the folded state
Solution Approach 2:
The system dynamically changes display parameters including format configuration, brightness, size, and position of visual information based on the detected fold state. By adjusting these parameters in real-time according to the fold condition, the system compensates for deformation effects and maintains reliable visual information display across the folded display surface
2Reliability
If the display format is adjusted to compensate for folding distortions, then visual information display quality is maintained, but the system complexity increases due to fold detection sensors and real-time format adjustment mechanisms
Solution Approach 1:
The system replaces complex mechanical distortion compensation mechanisms with electronic sensing and software-based format adjustment. Load cells provide electronic detection of fold states, and software algorithms dynamically adjust display formats, substituting mechanical complexity with electronic and computational solutions that achieve the same compensation effect with greater precision and control
3Measurement precision
If load cells are positioned to accurately detect fold states, then fold detection precision is improved, but the manufacturing complexity and precision requirements increase
Solution Approach 1:
The load cells are designed to serve multiple functions: detecting fold states, determining fold positions, and providing data for format adjustment calculations. By making the sensing system multi-functional, the patent reduces the need for separate specialized sensors, thereby lowering manufacturing precision requirements while maintaining adequate fold detection precision through the versatile load cell implementation
