Flexible Display Stacking Structure for Laser Cutting Waste Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for manufacturing flexible display assemblies result in a wide cut-off portion during laser cutting, leading to decreased layout efficiency and increased costs due to the need for a waste removal device to maintain a sufficient distance from the flexible display panel to prevent contamination.
Innovation Solution
A stacking structure for flexible display assemblies, featuring a lower protection film with a protruding edge for attaching the waste removal device, an upper protection film flush with the flexible display panel edge, and a support board between the panel and the lower protection film, allowing for a narrower edge removal region and improved layout efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the waste removal device maintains a sufficient distance from the flexible display panel to prevent contamination, then the panel is protected from contamination, but the cut-off portion width increases leading to decreased layout efficiency
Solution Approach 1:
The protection film is segmented into two functional zones: a protective region that covers the flexible display panel during cutting, and a protruding waste collection region that extends beyond the panel edge. This segmentation allows the waste removal device to collect cut-off portions directly at the cutting location without needing to maintain distance from the panel, thus preventing contamination while maintaining tight cutting margins for high layout efficiency.
Solution Approach 2:
The protection film acts as an intermediary structure between the laser cutting process and the flexible display panel. The protruding portion of the protection film serves as a mediator that intercepts and collects waste material, preventing it from contacting the panel. This intermediary mechanism enables the waste removal device to operate effectively without compromising panel safety or cutting efficiency.
2Object-affected harmful factors
If a wide cut-off portion is used to allow waste removal device to maintain distance from the panel, then contamination is prevented, but the utilization rate of the master flexible display panel decreases
Solution Approach 1:
The protection film is divided into a protective region aligned with the panel boundaries and a protruding waste collection region extending beyond the panel. This segmentation enables the cutting process to proceed with minimal margin (narrow cut-off portion) since the protruding film portion captures waste directly, thereby maximizing the usable area of the master flexible display panel and improving utilization rate.
Solution Approach 2:
The protection film extends in the lateral dimension beyond the panel edge, creating a three-dimensional structure where the protruding portion operates in a different spatial zone than the panel surface. This dimensional extension allows waste collection to occur outside the panel boundary without requiring lateral clearance, thus minimizing the cut-off width and maximizing panel utilization.

AI summary
A stacking structure for a flexible display assembly is provided, which is advantageous in that, an region of a lower protection film protruding from an region in a flexible display panel, serves as an region for a waste removal device to capture and discharge waste, and meets the needs of the waste removal device for waste removal and the flexible display panel is not contaminated. In addition, a width of an edge removal area of the flexible display panel decreases, a layout efficiency of the irregular-shaped flexible display assembly is thereby improved, and a utilization rate of a master flexible display panel greatly increases to save costs.
