Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the resolution of display panels increases, the layout space becomes smaller, making it difficult to connect initialization signal line patterns in the same row, which raises production costs.
Innovation Solution
A display panel design that includes a substrate with an initialization signal line layer and an anode layer stacked sequentially, featuring a first auxiliary signal line layer with a grid structure in the anode spacing area, allowing the initialization signal line patterns to be coupled to the first auxiliary signal line layer.
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 located between the initialization signal line layer and the anode layer, utilizing the vertical dimension (z-axis) to resolve the horizontal layout space constraint. The auxiliary signal line layer provides additional signal transmission pathways that enable connection of initialization signal line patterns without increasing the planar area, thus maintaining high display resolution while solving the connectivity problem.
Solution Approach 2:
The first auxiliary signal line layer acts as an intermediary between the initialization signal line layer and the anode layer. It includes auxiliary signal line patterns that extend into the anode spacing area and are insulated from the anode pattern, serving as a mediator to transmit initialization signals to sub-pixel areas where direct connection would be difficult due to space constraints.
2Reliability
If the initialization signal line patterns are connected across sub-pixel areas, then signal transmission is improved, but the device structure becomes more complex
Solution Approach 1:
The first auxiliary signal line layer serves multiple functions: it transmits initialization signals to sub-pixel areas, extends into the anode spacing area to reach difficult-to-connect regions, and maintains insulation from the anode pattern. This multi-functionality reduces the need for additional separate structures, thereby improving signal transmission without proportionally increasing device complexity.
Solution Approach 2:
The signal transmission system is segmented into multiple layers: the initialization signal line layer for primary signal distribution and the first auxiliary signal line layer for supplementary connection. This segmentation allows each layer to have optimized functions, with the auxiliary layer specifically handling connections in space-constrained areas, thus improving overall signal transmission reliability while managing complexity through functional division.
