Engineering Contradiction Analysis
1Adaptability or versatility
If optical fingerprint sensing elements are integrated into self-luminous display pixels, then functionality is enhanced and structure is simplified, but manufacturing precision requirements increase
Solution Approach 1:
The patent merges the fingerprint sensing function and display function into a single integrated structure where optical fingerprint sensing elements are incorporated within self-luminous display pixels. This combining approach enhances functionality while managing manufacturing precision through unified design and process integration.
Solution Approach 2:
The self-luminous display pixels are designed to serve dual purposes: displaying visual information and performing optical fingerprint sensing. This multi-functionality approach allows a single structure to fulfill multiple roles, enhancing adaptability while reducing the need for separate dedicated components.
2Use of energy by stationary object
If self-luminous display pixels are used as light source for fingerprint acquisition, then power consumption is reduced and structure is simplified, but display quality may be affected
Solution Approach 1:
The self-luminous display pixels perform dual functions as both display elements and light sources for fingerprint sensing. By using the same pixels for both purposes, the system reduces power consumption compared to having separate backlight sources, while maintaining display quality through the inherent lighting capabilities of the self-luminous pixels.
Solution Approach 2:
The display pixels serve themselves by providing the light source for fingerprint acquisition without requiring external backlighting components. This self-service approach eliminates the need for separate lighting systems, reducing overall power consumption and structural complexity while maintaining functional performance.
