Integrated Display Document Manufacturing via Simultaneous Substrate Structuring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing documents with integrated displays are vulnerable to forgery since the display is typically attached or laminated, allowing a forger to easily replicate or replace it, and manufacturing costs are high due to separate production of display and circuit components.
Innovation Solution
Manufacturing an integrated display directly on a substrate along with the electronic circuit in a single process step, such as a structuring step, where the display and circuit components are formed simultaneously, reducing manufacturing time and costs, and enhancing security by requiring the same manufacturing capabilities for replication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the display is attached or laminated into the electronic document, then the document can be manufactured with a display, but the document becomes easier to forge
Solution Approach 1:
The patent merges the display component and circuit component into a single integrated structure manufactured in one process step. The display and circuit are formed simultaneously on the same substrate using the same manufacturing process, making them inseparable and thus preventing forgery by simply attaching a display to an existing document.
Solution Approach 2:
The manufacturing process performs preliminary actions by forming both the display and circuit components during the same structuring step. This simultaneous formation creates an integrated structure that cannot be replicated by simple attachment, as the display and circuit are created together in a single manufacturing process.
2Ease of manufacture
If the display is manufactured separately and laminated onto the document, then the display can be incorporated into the document, but manufacturing costs increase
Solution Approach 1:
The patent combines the manufacturing of the display component and circuit component into a single process step. Both components are formed simultaneously on the substrate using the same structuring process, eliminating the need for separate manufacturing and lamination steps, thus reducing overall manufacturing complexity.
Solution Approach 2:
The manufacturing process is designed to be universal, performing multiple functions simultaneously. The same structuring step that forms the circuit components also forms the display components, making the process multi-functional and reducing the total number of manufacturing steps required.
3Manufacturing precision
If the display and circuit components are manufactured separately, then each component can be optimized independently, but manufacturing time increases
Solution Approach 1:
The manufacturing process maintains continuity by forming both the display and circuit components in a single uninterrupted structuring step. The useful action of manufacturing continues without interruption, creating both components simultaneously rather than sequentially, thus reducing total manufacturing time while maintaining optimization through process integration.
