Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate fingerprint identification device is installed in the electronic apparatus, then fingerprint identification capability is achieved, but the volume and complexity of the electronic apparatus increase
Solution Approach 1:
The patent combines the fingerprint sensing layer with the touch panel structure, integrating two functions (touch sensing and fingerprint identification) into a single unified device. The fingerprint sensing layer is positioned between the touch layer and display layer, sharing the same physical space and structural framework, thereby eliminating the need for separate fingerprint identification devices and reducing overall apparatus volume.
Solution Approach 2:
The touch panel is designed to perform multiple functions: both touch sensing and fingerprint identification. The same touch panel structure serves dual purposes by incorporating the fingerprint sensing layer, allowing the device to function as both a touch interface and a biometric authentication system, thereby reducing the need for additional dedicated components.

Data Source
AI summary
The invention discloses a touch panel capable of identifying fingerprints. The touch panel includes a touch layer and a fingerprint sensing layer. The touch layer is used for sensing a specific location touched by a finger. The fingerprint sensing layer is disposed under the touch layer and includes a storage unit, multiple receiving modules, multiple transmitting modules, and a control module. The storage unit stores a first fingerprint data corresponding to the finger. Each receiving module respectively corresponds to one of the transmission modules. According to the specific location, one of the transmission modules transmits a signal, and the signal is then reflected by the finger to the corresponding receiving module. The control module converts the signal received by the receiving module into a second fingerprint data and then determines whether the second fingerprint data conforms to the first fingerprint data.
