Window Member Pattern Layer Direct Glass Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing window members for portable terminals require a complex manufacturing process and increased costs due to the need for a film layer that does not contribute to the function or structure, and the pattern layer is not directly in contact with the glass member, limiting design precision and fineness.
Innovation Solution
A window member with a pattern layer directly contacting the glass member, formed using silk-screen printing of transparent ultraviolet curing resin with fine patterns, and a deposition layer with reflective properties, eliminating the need for a separate film layer and simplifying the manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a film layer is used to attach the pattern layer to the glass member, then the pattern layer can be formed, but the manufacturing process becomes complex and costs increase
Solution Approach 1:
The patent removes the film layer from the structure, allowing the pattern layer to directly contact the glass member. This extraction of the unnecessary film layer simplifies the manufacturing process and reduces structural complexity while maintaining the functional integrity of the window member assembly.
Solution Approach 2:
The pattern layer is merged directly with the glass member surface through direct contact without an intervening film layer. This merging eliminates the need for separate attachment processes and reduces the number of components, thereby simplifying both manufacturing and structure.
2Ease of manufacture
If a film layer is inserted between the pattern layer and glass member, then attachment is possible, but manufacturing costs increase
Solution Approach 1:
The film layer is extracted from the assembly, eliminating material costs associated with purchasing and processing the film. This direct contact approach reduces the quantity of substances required while maintaining attachment functionality through the bonding member positioned at the periphery.
3Manufacturing precision
If the pattern layer does not directly contact the glass member, then a film layer is needed for attachment, but design precision and fineness are limited
Solution Approach 1:
By removing the film layer that separates the pattern layer from the glass member, the patent enables direct contact and precise pattern formation on the glass surface. This extraction allows for finer design details to be accurately transferred without the interference or thickness limitations of an intermediate film layer.

AI summary
A window member includes: a glass member; a display member wherein the glass member has a bottom surface which faces and overlays the display member and a pattern layer provided on a first surface of the glass member and having a fine pattern. The pattern layer is silk-screen printed on the first surface of the glass member to directly contact the surface of the glass member. A method of manufacturing a window member, includes: forming a pattern layer such that the pattern layer contacts a surface of the glass member along a periphery of the glass member. The pattern layer is formed at a location which is offset inward from a periphery of the glass member.
