Display Panel Conductor Routing via Folded Substrate Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional display panels face issues where the reduction in conductor width to accommodate a larger display region leads to conductor breakage and defects due to insufficient space in the peripheral region.
Innovation Solution
The display panel design includes a thin film transistor array substrate and a color filter substrate with conductors connected via adapters and elastic conductive blocks, allowing the conductor to be transferred to the color filter substrate, maintaining adequate width and preventing breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the size of the display region is increased, then the display area is improved, but the peripheral region size is reduced and conductor width must be decreased leading to conductor breakage
Solution Approach 1:
The conductor is folded back into the display region area, utilizing the vertical/dimensional space rather than only horizontal peripheral space. This allows the conductor to maintain adequate width while still providing sufficient connection paths, effectively moving the conductor from a 2D peripheral layout to a 3D configuration that incorporates display region space.
Solution Approach 2:
The conductor is designed with a flexible folded structure that can adapt to spatial constraints. By making the conductor configuration dynamic and adaptable rather than fixed and linear, the design allows the conductor to navigate the limited peripheral region while maintaining adequate width through strategic folding patterns.
2Quantity of substance
If the width of the conductor is decreased to fit more conductors in the peripheral region, then the number of conductors is maintained, but the conductor becomes broken and defective
Solution Approach 1:
Instead of reducing conductor width to fit more conductors in the limited peripheral space, the invention utilizes the display region area by folding the conductor back into this space. This dimensional reconfiguration allows maintaining adequate conductor width while still accommodating the required number of conductors through optimized spatial arrangement.
Solution Approach 2:
The conductor is folded back into the display region, effectively nesting the conductor within the existing display area structure. This nested configuration allows the conductor to utilize space that would otherwise be unused, maintaining conductor width while fitting within the overall panel dimensions.

AI summary
A display panel and a display device are provided. The display panel has a thin film transistor array substrate, a color filter substrate, and a liquid crystal layer. An area of the thin film transistor array substrate corresponding to the peripheral region of the display panel is disposed with a first conductor and a conductive member, and an area of the color filter substrate corresponding to the peripheral region is disposed with a second conductor for connecting to the first conductor and the conductive member. The present disclosure can avoid the conductor being broken and defective from decreasing the width of the conductor.
