Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display apparatuses with openings, the use of laser beams or mechanical polishing can generate gas or foreign matter during the process of creating openings, which affects the manufacturing process and the quality of the final product.
Innovation Solution
A display apparatus and manufacturing method that incorporates a substrate with an opening region and a display area, featuring a thin film encapsulation layer with organic and inorganic layers, and a mask assembly system with concavo-convex shaped openings to minimize gas and foreign matter generation by precise deposition of materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If laser beam or mechanical polishing is used to create openings, then opening formation is achieved, but gas or foreign matter is generated during the process
Solution Approach 1:
The patent extracts and removes specific layers (organic encapsulation layer, inorganic encapsulation layer, functional layer) to form openings, avoiding the use of laser beams or mechanical polishing that generate gas or foreign matter. This layer-by-layer removal approach achieves opening formation without harmful byproducts.
Solution Approach 2:
The patent performs preliminary deposition of encapsulation layers and functional layers in a controlled sequence before opening formation. By pre-arranging layers with specific properties (organic and inorganic encapsulation), the subsequent opening creation becomes a simple removal process rather than a destructive machining process, eliminating gas and foreign matter generation.
2Area of stationary object
If multiple layers are arranged to create openings, then display area is increased, but manufacturing complexity increases
Solution Approach 1:
The patent segments the encapsulation structure into distinct organic and inorganic layers, each serving specific functions. This segmentation allows selective removal of layers to create openings while maintaining control over the manufacturing process, preventing excessive complexity despite increased display area.
Solution Approach 2:
The patent applies different material properties to different regions: organic encapsulation layers provide flexibility and moisture barrier, while inorganic layers provide hardness and additional barrier properties. This local differentiation of material qualities enables precise control during opening formation, managing manufacturing complexity through functional specialization.
