Flexible Display Panel Bending for Narrow Border Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flexible display panel manufacturing methods result in large electrode bonding regions with wide borders, which hinder the achievement of a narrow border design, especially in touch control display panels.
Innovation Solution
The flexible substrate is bent at the electrode bonding region from the display surface to the non-display surface, allowing for a reduced horizontal space occupation and enabling the attainment of narrow borders through high-precision attachment or laser cutting, while maintaining the structural integrity and functionality of the display panel.

Engineering Contradiction Analysis
1Area of moving object
If the flexible substrate is bent at the electrode bonding region from the display surface to the non-display surface, then the horizontal space occupation is reduced and narrow border is achieved, but the manufacturing complexity increases due to high-precision attachment or laser cutting requirements
Solution Approach 1:
The flexible substrate is bent into a curved shape at the electrode bonding region, transitioning from a flat configuration to a three-dimensional curved structure. This curvature reduces the horizontal projection area of the electrode bonding region while maintaining its functional area, enabling narrow border design in flexible display panels and touch control panels.
2Shape
If the flexible substrate is bent at the electrode bonding region, then the overall thickness and aesthetic appeal are enhanced, but the structural integrity must be maintained during bending
Solution Approach 1:
The bending is applied locally only at the electrode bonding region rather than across the entire flexible substrate. This localized curvature allows the display region and other functional areas to remain flat and intact, maintaining structural integrity while achieving the desired thickness enhancement and aesthetic appearance at specific locations.

AI summary
A flexible display panel includes a flexible substrate with a display region and an electrode bonding region. The flexible substrate includes a display surface and a non-display surface opposite to the display surface. Wherein the flexible substrate at a position corresponding to the electrode bonding region is bent along a direction from the display surface to the non-display surface.
