Touch Panel Hollow Areas for Full-Screen Fingerprint Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display panels with integrated fingerprint identification modules are limited by their non-display area placement, hindering full-screen designs.
Innovation Solution
A touch panel design featuring a touch film layer with preset hollow areas, allowing the orthographic projection of the fingerprint identification film layer to be located within these hollows, thus avoiding interference with the display and enabling full-screen fingerprint identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the fingerprint identification module is arranged in the non-display area, then the fingerprint identification function can be realized, but the full-screen design of the display panel is limited
Solution Approach 1:
The patent merges the fingerprint identification module with the display panel structure by arranging the fingerprint identification film layer in the hollow area of the touch film layer, which is located within the display area. This integration allows the fingerprint identification function to be combined with the display structure, achieving full-screen design while maintaining functional capability.
Solution Approach 2:
The patent utilizes the hollow area dimension within the touch film layer structure to accommodate the fingerprint identification film layer. By using the vertical/hierarchical arrangement within the multi-layer structure, the fingerprint module is positioned in a spatial dimension that does not interfere with the display function, enabling full-screen coverage.
2Area of stationary object
If the fingerprint identification film layer is placed in the display area, then full-screen fingerprint identification is achieved, but it may interfere with the display function
Solution Approach 1:
The patent applies local quality by utilizing the hollow area of the touch film layer as a specific location where the fingerprint identification film layer can be placed without affecting the surrounding display areas. The hollow area serves as a localized zone with different functional requirements, allowing fingerprint identification while preserving display quality in other regions.
Solution Approach 2:
The hollow area of the touch film layer acts as an intermediary structure that mediates between the fingerprint identification film layer and the display film layer. This intermediate zone allows the fingerprint module to be positioned within the display area while preventing direct interference with the display function, as the hollow structure provides spatial separation.
