Electro-Optical Panel Terminal Layout for Reduced Wiring Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electro-optical panels face inefficiencies in wiring due to insufficient arrangement of terminals, leading to reduced display region and increased wiring region, limiting the number and arrangement of segment electrodes.
Innovation Solution
The electro-optical panel is configured with a driver that includes multiple terminal groups along a side, each containing segment and common terminals, allowing efficient wiring by routing segment and common wires on both substrates, optimizing the arrangement of electrodes and reducing wiring regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If terminals are arranged in a conventional manner, then the driver can be simplified, but the wiring region increases and the display region decreases
Solution Approach 1:
The driver is divided into multiple terminal groups (first terminal group and second terminal group) arranged along the first side, with each group containing segment terminals and common terminals. This segmentation allows independent wiring control for different electrode groups, enabling the wiring regions to be optimized and reduced while maintaining display region size.
Solution Approach 2:
Terminals are arranged along the first side of the driver in a linear sequence, utilizing the lateral dimension to organize multiple terminal groups. This dimensional arrangement allows efficient wiring routing on both substrates by progressing through terminal groups in sequence, reducing the need for complex multi-directional wiring.
2Area of stationary object
If segment electrodes and common electrodes are mixed on the same substrate, then wiring becomes complex, but the display region is reduced
Solution Approach 1:
The electrode structure is segmented into first segment electrode groups and first common electrode groups on the first substrate, and second segment electrode groups and second common electrode groups on the second substrate. This segmentation allows dedicated wiring paths for segment and common electrodes on each substrate, improving wiring efficiency while maintaining full display region.
Solution Approach 2:
Different substrates are assigned different electrode configurations: the first substrate contains first segment and first common electrodes, while the second substrate contains second segment and second common electrodes. This local differentiation optimizes wiring routes for each substrate type, avoiding the complexity of mixing electrode types on the same substrate.
3Ease of manufacture
If terminal groups are arranged along the first side, then wiring efficiency improves, but the driver structure becomes more complex
Solution Approach 1:
The driver structure is segmented into multiple terminal groups arranged along the first side, with each group containing segment terminals and common terminals. This segmentation, while increasing structural detail, enables systematic wiring routing that improves overall wiring efficiency and reduces the display region requirement.
Solution Approach 2:
Each terminal group serves multiple functions: it provides both segment terminals for segment electrode control and common terminals for common electrode control. This multi-functionality within each terminal group reduces the total number of separate terminal arrangements needed, optimizing the balance between wiring efficiency and driver structure complexity.
