Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices lack the ability to enhance sensing sensitivity to external stimuli while maintaining flexibility and adaptability in size and shape.
Innovation Solution
Incorporating a sensing material layer between a first elastic member and a display portion, which includes island patterns separated by slits, with sensing lines intersecting at the sensing material layer to increase sensitivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a sensing material layer is incorporated into the display panel, then sensing sensitivity to external stimuli is improved, but device complexity increases
Solution Approach 1:
The sensing material layer is integrated within the display panel structure, merging the sensing function with the display structure. The sensing material layer is positioned between the first elastic member and the display portion, sharing the same space and reducing the need for separate sensing modules, thereby improving sensing sensitivity while managing device complexity.
Solution Approach 2:
The display panel is designed to perform multiple functions: display and sensing. The sensing material layer enables the display panel to detect external stimuli (such as pressure or touch) in addition to its primary display function. This multi-functionality approach allows the same structure to serve dual purposes, improving sensing capability without proportionally increasing device complexity.
2Adaptability or versatility
If the display device is made flexible and adaptable in size, then adaptability is improved, but sensing sensitivity to external stimuli deteriorates
Solution Approach 1:
The display portion is divided into multiple island patterns spaced apart from each other with slits between them. The sensing material layer is positioned to overlap with these slits, creating multiple discrete sensing zones. This segmentation allows the flexible display to maintain sensing sensitivity across different regions while accommodating size changes and flexible configurations.
Solution Approach 2:
The sensing material layer is positioned in a specific spatial relationship (overlapping the slits) within the multi-layer display structure. This three-dimensional arrangement allows the sensing function to be integrated without compromising the flexible and adaptable nature of the display, as the sensing sensitivity is enhanced at the slit regions where the elastic member can deform more freely.
