Display Substrate With Segmented Bending Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses have a significant peripheral area that reduces the effective display area and can lead to increased complexity in wiring designs, causing interference and making it difficult to achieve high-resolution displays.
Innovation Solution
The display apparatus is designed with a substrate that includes a display area and a peripheral area, where the peripheral area is divided into two bending areas, one for the data driving circuit and the other for the gate driving circuit, allowing for a more efficient use of space and reduced wire concentration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the peripheral area is reduced to maximize display area, then the display area is increased, but the wiring design becomes more complex and wires may interfere with each other
Solution Approach 1:
The peripheral area is divided into separate bending areas for different driving circuits (data driving circuit and gate driving circuit), which segments the wiring paths and reduces interference between wires while maintaining a compact overall structure
Solution Approach 2:
The patent utilizes the third dimension by creating bending areas that extend vertically or in alternative spatial dimensions, allowing wires to be routed in different layers or planes, thus reducing wire concentration and interference while maintaining a reduced peripheral footprint
2Area of moving object
If driving circuits are placed in the peripheral area, then the display area is maximized, but the peripheral area increases reducing the effective display area
Solution Approach 1:
The peripheral area incorporates bending areas with curved or folded configurations, allowing driving circuits to be positioned in a compact manner that reduces the overall peripheral footprint while maintaining functional separation and wiring efficiency
3Area of stationary object
If wires are concentrated to reduce peripheral area, then the peripheral area is reduced, but wire interference increases and display quality deteriorates
Solution Approach 1:
The wiring system is segmented into separate routing paths for different signal types (data signals and gate signals), with dedicated bending areas for each driving circuit, which prevents wire interference while maintaining a compact peripheral structure
Solution Approach 2:
The bending areas serve as intermediary zones that facilitate wire routing and separation, acting as buffer regions that prevent direct interference between wires from different driving circuits while maintaining spatial efficiency
