Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices face challenges in reducing dead space due to bent driving and sensing signal transfer films, which affect the overall design and functionality.
Innovation Solution
The implementation of a side surface connection electrode structure that includes straight, extension, and inclined portions to connect the sensing electrode and signal transfer film, reducing the bending radius of the driving film and ensuring the sensing signal transfer film is not bent, thereby minimizing dead space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sensing signal transfer film is bent to connect the sensing electrode and the signal transfer film, then the connection between components is achieved, but the dead space increases and the structural integrity is compromised
Solution Approach 1:
The connection structure transitions from a planar bent film configuration to a three-dimensional arrangement using a side surface connection electrode structure. This structure extends along the side surface of the display panel, utilizing the vertical dimension to achieve connection without requiring the film to bend within the plane, thereby reducing dead space while maintaining connectivity.
2Adaptability or versatility
If the driving film is bent to accommodate the sensing structure, then the sensing structure can be integrated, but the bending radius increases device complexity and reduces reliability
Solution Approach 1:
The connection function is segmented into separate components: a side surface connection electrode structure that handles the electrical connection along the side surface, and the main driving film that remains relatively flat. This segmentation eliminates the need for the driving film to have complex bending radii, reducing device complexity while maintaining sensing structure integration.
3Ease of operation
If the sensing signal transfer film is bent, then the components can be connected, but the signal transfer integrity is compromised
Solution Approach 1:
The side surface connection electrode structure acts as an intermediary between the sensing electrode and the signal transfer film. Instead of bending the signal transfer film directly, the intermediary connection structure facilitates signal transfer along the side surface, maintaining the integrity of the signal transfer film while achieving component connection.
