Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing resolution of display panels leads to limited layout space, making it difficult to connect initialization signal line patterns in the same row, thereby increasing production costs.
Innovation Solution
A display panel design that includes a first auxiliary signal line layer and conductive connection portions to couple initialization signal line patterns in each sub-pixel area, allowing for sequential coupling without requiring additional spacing areas, thus reducing the need for via holes and simplifying the manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the resolution of the display panel is increased, then the display quality is improved, but the layout space becomes smaller making it difficult to connect initialization signal line patterns
Solution Approach 1:
The patent introduces a first auxiliary signal line layer above the initialization signal line layer to establish connections in the vertical dimension. This allows initialization signal line patterns in the same row to be connected through via holes penetrating through the auxiliary signal line layer, effectively utilizing the third dimension to resolve the lateral space constraint caused by high resolution requirements.
2Reliability
If via holes are added to connect initialization signal line patterns, then connectivity is improved, but the manufacturing process becomes more complex and costly
Solution Approach 1:
The first auxiliary signal line layer serves multiple functions: it provides a pathway for connecting initialization signal line patterns in the same row, maintains signal transmission functionality, and integrates with the existing layer structure. This multi-functionality reduces the need for separate dedicated connection structures, thereby simplifying the overall manufacturing process while ensuring reliable connectivity.
