Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touch display apparatuses require additional assembly steps and increased weight due to separate manufacturing of touch sensing and fingerprint recognition components, leading to complexity and user burden.
Innovation Solution
Integration of touch sensing and fingerprint recognition electrode sets within the same apparatus, where the fingerprint recognition electrode set is formed on the display panel or cover plate, and the touch sensing electrode set is between the display panel and cover plate, reducing assembly complexity and weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fingerprint recognition apparatus is manufactured separately from touch display apparatus, then fingerprint recognition function is achieved, but assembly complexity and weight increase
Solution Approach 1:
The patent combines the fingerprint recognition electrode set and touch sensing electrode set into a single integrated structure formed on the display panel or cover plate. This merging eliminates the need for separate assembly of independent fingerprint recognition apparatus, thereby reducing assembly complexity while maintaining fingerprint recognition functionality.
Solution Approach 2:
The patent creates a multi-functional electrode structure that simultaneously serves as both touch sensing electrodes and fingerprint recognition electrodes. This universal design allows a single component to perform multiple functions, eliminating the need for separate dedicated fingerprint recognition apparatus and reducing overall device complexity.
2Reliability
If fingerprint recognition apparatus is manufactured separately from touch display apparatus, then fingerprint recognition function is achieved, but weight of apparatus increases
Solution Approach 1:
The patent merges the fingerprint recognition apparatus with the touch display apparatus by forming both electrode sets on the same substrate (display panel or cover plate). This integration eliminates redundant structural components and reduces the overall weight of the apparatus while preserving fingerprint recognition capability.
Solution Approach 2:
The patent employs a multi-functional electrode structure that serves dual purposes as both touch sensing and fingerprint recognition elements. This universal design eliminates the need for separate weight-bearing structures for fingerprint recognition, thereby reducing total apparatus weight.
3Reliability
If touch sensing electrode set and fingerprint recognition electrode set are manufactured separately, then各自功能 is achieved, but manufacturing process complexity increases
Solution Approach 1:
The patent combines the manufacturing processes for touch sensing electrodes and fingerprint recognition electrodes into a single integrated fabrication process. Both electrode sets are formed simultaneously on the display panel or cover plate using the same manufacturing steps, thereby simplifying the manufacturing process while ensuring both functions are achieved.
Solution Approach 2:
The patent creates a universal electrode structure that can be manufactured using a single set of manufacturing processes for both touch sensing and fingerprint recognition functions. This approach eliminates the need for separate manufacturing lines or additional fabrication steps, significantly easing the manufacturing process.

AI summary
A touch display apparatus capable of fingerprint recognition includes a display panel, a cover plate, a touch sensing electrode set and a fingerprint recognition electrode set. The display panel includes a first surface. The cover plate covers the first surface of the display panel, and includes a second surface facing the first surface of the display panel. The touch sensing electrode set is disposed between the display panel and the cover plate. The fingerprint recognition electrode set is directly formed on the first surface of the display panel or the second surface of the cover plate. The cover plate further covers the fingerprint recognition electrode set.
