Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sensor is disposed under the display panel, then the display device can include a sensor for biometric recognition, but the performance is degraded due to recognition through multiple layers and parts
Solution Approach 1:
The patent merges the sensor and display panel into a single integrated structure where the sensor is embedded within the display panel's internal layers. This combination eliminates the need for separate sensor modules mounted on the outside, reducing the number of components and layers while maintaining sensor performance for biometric recognition.
2Ease of manufacture
If the sensor is manufactured as a separate module and mounted on the outside of the display panel, then the sensor can be independently manufactured, but there are limitations in terms of design and usability
Solution Approach 1:
The integrated sensor-display panel structure serves multiple functions within a single component. The display panel not only displays information but also performs biometric recognition through the embedded sensor, enabling features like fingerprint sensing, pulse detection, and touch detection without requiring separate sensor modules.
3Adaptability or versatility
If an embedded sensor is proposed with the sensor embedded in the display panel, then seamless integration is achieved, but it is difficult to implement due to different performance and physical properties required for the display panel and sensor
Solution Approach 1:
The patent applies different material properties and structural characteristics to different regions of the display panel. The sensor region is designed with specific properties (such as light absorption characteristics and electrical conductivity) that differ from the display region, allowing each area to perform its intended function while being part of the same integrated structure.
