Solution Overview
Problem
As panel size increases, conventional color filters face issues with insufficient area voltage due to increased conductive distance, leading to decay in voltage levels and inefficient signal transmission between transfer pads.
Innovation Solution
The implementation of one or more conductive layers over a light shielding layer, electrically connected to an electrode layer, forming a parallel structure that reduces conductive resistance and eliminates the need for multiple transfer pads, thereby enhancing voltage transmission and reducing material costs.

Engineering Contradiction Analysis
1Area of stationary object
If panel size is increased, then display area is improved, but voltage level decays due to increased conductive distance
Solution Approach 1:
The conductive layer is divided into multiple parallel strips instead of a single continuous layer. This segmentation creates multiple parallel conduction paths, reducing the overall conductive resistance and preventing voltage level decay as panel size increases.
Solution Approach 2:
The invention transitions from a single-layer conductive structure to a multi-strip parallel structure, effectively adding a dimensional aspect to the conduction path. This parallel arrangement in the planar dimension reduces resistance without increasing vertical complexity.
2Area of stationary object
If panel size is increased, then display area is improved, but conductive resistance increases
Solution Approach 1:
The conductive layer is segmented into multiple parallel strips, creating multiple conduction paths. This reduces the equivalent conductive resistance by providing parallel pathways for current flow, counteracting the increased resistance from larger panel dimensions.
Solution Approach 2:
Multiple parallel conductive strips are combined to form a composite conductive system. The parallel combination of multiple conductive paths results in lower overall resistance compared to a single path, effectively managing conductive resistance in large panels.
3Reliability
If multiple transfer pads are used, then signal transmission is improved, but material cost and fabrication time increase
Solution Approach 1:
Multiple transfer pad functions are merged into the parallel conductive strip structure. The conductive strips themselves serve as both signal transmission paths and connection elements, eliminating the need for separate transfer pads and reducing fabrication steps.
Solution Approach 2:
The parallel conductive strips perform multiple functions: they provide signal transmission, reduce conductive resistance, and serve as connection elements between different layers. This multi-functionality eliminates the need for dedicated transfer pads, reducing material cost and fabrication time.
