Display Panel Bezel Wiring Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in display panel design is to effectively arrange circuits in a narrow bezel while maintaining a high screen-to-body ratio and avoiding complex wiring that can lead to short-circuiting and increased border width, which hinders the development of thinner and lighter displays.
Innovation Solution
The display panel design includes a first and second display area with scan signal lines and control circuits arranged in a cascaded manner, allowing for simplified wiring and reduced border width by connecting scan signal lines alternately to scan control circuits, thereby reducing the complexity of the circuit structure and releasing space for a narrower bezel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If circuits are arranged in a narrow bezel to achieve high screen-to-body ratio, then the screen-to-body ratio is improved, but the circuit wiring becomes complex and prone to short-circuiting
Solution Approach 1:
The display area is divided into a first display area and at least one second display area, with scan signal lines and control circuits separately arranged in each area. This segmentation allows independent wiring paths that avoid complex interconnections and potential short-circuits while maintaining high screen-to-body ratio.
Solution Approach 2:
Scan signal lines are arranged to extend in both first and second directions, creating a two-dimensional wiring pattern. Control circuits are positioned at terminals in different directions, utilizing spatial dimensionality to simplify connections and reduce wiring complexity in the narrow bezel area.
2Weight of moving object
If circuits are arranged in a narrow bezel to achieve thinner and lighter displays, then the weight is reduced, but the circuit wiring becomes complex and prone to short-circuiting
Solution Approach 1:
The display structure is segmented into multiple display areas with separate scan control circuits for each area. This segmentation reduces the overall circuit complexity in the narrow bezel, enabling thinner and lighter design without compromising wiring reliability.
Solution Approach 2:
Instead of extending wiring across the entire narrow bezel, the patent positions control circuits at the terminals of scan signal lines in different directions. This inverted arrangement approach simplifies wiring by connecting control circuits locally at terminals rather than routing signals across the entire display area.
3Device complexity
If scan signal lines are connected to scan control circuits in a conventional manner, then the wiring becomes complex, but if connected alternately as in this patent, then the wiring is simplified and short-circuiting is prevented
Solution Approach 1:
Scan signal lines are divided into different directional groups (first direction and second direction), with dedicated control circuits for each group. This segmentation creates separate wiring paths that do not intersect, simplifying the wiring structure and eliminating short-circuit risks.
Solution Approach 2:
The patent utilizes two-dimensional arrangement of scan signal lines extending in different directions, with control circuits positioned at terminals in corresponding directions. This dimensional approach creates orthogonal wiring paths that naturally prevent intersections and short-circuits while maintaining wiring simplicity.
