FMLOC Display Panel Binding Area Layer Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible Multi-Layer On Cell (FMLOC) touch-control products face challenges such as lack of design experience and low production yield due to issues like film layer deformation and wrinkling caused by water absorption, particularly in the binding area where organic and inorganic layers overlap.
Innovation Solution
The display panel design includes a touch-control layer with non-overlapping projections of inorganic and organic layers in the binding area, ensuring no overlap between the first inorganic layer and the first organic layer, which prevents deformation and wrinkling, and additional protection layers to enhance film stability and adhesion, allowing for a narrow frame design and improved production yield.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If organic and inorganic layers are overlapped in the binding area, then film layer coverage is improved, but film layer deformation and wrinkling occur due to water absorption
Solution Approach 1:
The patent divides the binding area into distinct regions where organic layers and inorganic layers are spatially separated rather than overlapped. The first organic layer is positioned in a first binding area while the first inorganic layer is positioned in a second binding area, preventing their projections from overlapping on the driving backplane. This segmentation eliminates the water absorption-induced deformation and wrinkling that occurs when layers are overlapped.
2Length of stationary object
If FMLOC process is applied for touch control, then screen thickness is reduced, but design experience and production yield are insufficient
Solution Approach 1:
The patent applies different structural configurations to different areas of the display panel. In the binding area, the organic and inorganic layers are spatially separated to prevent deformation, while in the display area, the layers can be overlapped for proper touch control functionality. This local differentiation allows the FMLOC process to achieve thin screen thickness while maintaining high production yield through optimized local structures.
3Area of stationary object
If frame width is reduced, then display area is maximized, but film layer structure stability becomes compromised
Solution Approach 1:
The patent extracts the problematic overlapping structure from the binding area and relocates the organic and inorganic layers to separate spatial zones. By taking out the overlapping configuration that causes instability and placing layers in distinct binding areas, the patent enables narrower frame widths with maximized display areas while maintaining film layer structure stability through the separated arrangement.
