Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transparent and flexible displays are not suitable for video applications due to high resistivity in ITO layers, limited flexibility, and reduced resolution from using stretchable electronics, which restricts their ability to maintain high-resolution video display while being deformable.
Innovation Solution
A real-time deformable and transparent display system using a flexible circuit board with embedded light-emitting diodes (LEDs) and stretchable conducting paths, where the circuit board is partially removed to enhance transparency and deformability, and local drivers are used to reduce connections and increase redundancy, allowing for high-resolution video display and multiple directional bending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If ITO layers are used for transparency and conductivity, then optical transparency is improved, but electrical resistivity increases causing slow switching circuits
Solution Approach 1:
The patent removes the ITO layer from the display structure entirely, extracting the problematic component that caused the contradiction between transparency and conductivity. The display achieves transparency through the transparent substrate and transparent encapsulation layers, while conductivity is provided by separate transparent conductive materials in the electrode structures, eliminating the reliance on high-resistivity ITO for both functions.
Solution Approach 2:
The patent applies different material properties to different layers: the substrate and encapsulation layers use transparent materials for optical clarity, while specific electrode regions use transparent conductive materials optimized for electrical conductivity. This local differentiation allows each layer to optimize its primary function without compromising the other.
2Adaptability or versatility
If stretchable electronics with serpentine circuits are used, then flexibility and stretching capability are improved, but resolution decreases due to reduced space between components
Solution Approach 1:
The display is divided into modular tile units that can be independently manufactured with high precision and then assembled into larger flexible configurations. Each tile maintains standard resolution characteristics, while the overall system achieves flexibility through the modular arrangement and flexible substrate connections between tiles.
Solution Approach 2:
The patent transitions from planar 2D flexibility to 3D spatial flexibility by stacking multiple transparent display tiles at different depths and angles. This volumetric arrangement allows the display to bend and fold in three dimensions while maintaining pixel density and resolution on each individual tile surface.
3Adaptability or versatility
If frequent bending and deforming are performed, then adaptability is improved, but wear and connection failures increase
Solution Approach 1:
The patent uses flexible printed circuit boards (FPCBs) with meander-patterned conductive traces that can accommodate repeated bending without breaking. The thin-film construction allows the circuits to flex elastically, distributing mechanical stress throughout the structure rather than concentrating it at rigid connection points.
Solution Approach 2:
The meander circuit design预先 provides stress relief pathways that absorb bending forces before they can damage critical connections. The serpentine geometry acts as a mechanical cushion, allowing the circuit to flex repeatedly without reaching failure thresholds.
4Adaptability or versatility
If more material is used for stretchable interconnections, then stretching functionality is improved, but available space for high-resolution pixels decreases
Solution Approach 1:
The display is segmented into discrete tile modules where stretching interconnections are only required between tiles, not within each tile. This allows each tile to maintain high pixel density with minimal inter-pixel spacing, while the stretching capability is concentrated in the inter-tile connection regions.
Solution Approach 2:
The patent utilizes the third dimension (depth/layering) to accommodate stretching interconnections by routing them through vertical pathways and utilizing the space between stacked display layers, rather than consuming horizontal pixel space.
