Display Panel Signal Lead Routing for Narrow Non-Display Region
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display panels have a wide non-display region, which necessitates optimization to improve the screen-to-body ratio and display effectiveness.
Innovation Solution
The display panel is designed with a layout where the touch signal leads and data signal leads are disposed on different sides of the display region within the non-display region, allowing for a more compact arrangement and reduced width of the non-display region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the non-display region is made wide to accommodate all signal leads, then the touch units and light-emitting devices can be properly connected, but the screen-to-body ratio is reduced and display effectiveness is compromised
Solution Approach 1:
The patent segments the signal leads into two distinct groups: touch signal leads extending from the first side and data signal leads extending from the second side. This segmentation allows each group to be routed to different locations in the non-display region, enabling compact arrangement while maintaining all necessary connections without requiring a wide non-display region.
Solution Approach 2:
The patent utilizes the lateral dimension of the display panel by routing touch signal leads from the first side and data signal leads from the second side in opposite directions. This dimensional arrangement allows both signal lead types to be accommodated in the non-display region without increasing its width, thereby preserving the screen-to-body ratio while ensuring proper connectivity.
2Area of stationary object
If the non-display region width is reduced to improve screen-to-body ratio, then display effectiveness is improved, but the arrangement of touch signal leads and data signal leads becomes more difficult
Solution Approach 1:
By segmenting the signal leads into touch signal leads and data signal leads with distinct routing paths, the patent simplifies the arrangement process. Each lead type can be independently positioned and connected to its respective component, reducing the complexity of managing all leads within a compact non-display region.
Solution Approach 2:
The patent employs asymmetric routing where touch signal leads extend from the first side and data signal leads extend from the second side in opposite directions. This asymmetric arrangement optimizes space utilization in the non-display region, making it easier to accommodate all leads within a reduced width while maintaining clear separation and simple connectivity.
3Device complexity
If all signal leads are arranged on one side of the display region, then the layout is simpler, but the non-display region must be wider to accommodate all leads
Solution Approach 1:
The patent divides the signal leads into two segments with different routing destinations: touch signal leads going to the first side and data signal leads going to the second side. This segmentation allows a simpler layout where each lead type follows its own dedicated path, eliminating the need for a wide non-display region while maintaining layout manageability.
Solution Approach 2:
Instead of arranging all leads vertically on one side, the patent distributes them horizontally to opposite sides of the display region. This dimensional redistribution allows the non-display region to maintain a compact width while accommodating all necessary leads through optimized spatial arrangement in the lateral dimension.
