Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display device uses separate sensing systems for fingerprint detection and electronic pen detection, then each function can be detected independently, but the device complexity increases and simultaneous detection capability is limited
Solution Approach 1:
The patent combines fingerprint sensing pixels and electronic pen sensing pixels into a single integrated sensing panel. The sensing panel includes both types of pixels that can simultaneously detect fingerprint inputs and electronic pen inputs without requiring separate sensing systems, thereby reducing overall device complexity while maintaining versatile detection capabilities.
Solution Approach 2:
The sensing panel is designed with multi-functional pixels that can detect different types of inputs (fingerprint and electronic pen) within the same sensing structure. This universal sensing approach allows the device to handle multiple input modalities through a unified system rather than requiring dedicated separate systems for each function.
2Productivity
If the sensing panel integrates both fingerprint sensing pixels and electronic pen sensing pixels, then simultaneous detection is enabled, but the manufacturing precision requirements increase
Solution Approach 1:
The sensing panel is divided into distinct regions: a first region containing fingerprint sensing pixels and a second region containing electronic pen sensing pixels. This segmentation allows each pixel type to be manufactured and positioned with appropriate precision requirements for its specific function, while the overall panel achieves high input detection efficiency through the coordinated operation of both regions.
