Glass Laminate Colored-Layer Structure for Scratch-Free Seamless Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face issues with scratch resistance and seamlessness, particularly in configurations with transmission portions, leading to potential discomfort for users.
Innovation Solution
A glass laminate comprising a glass substrate with functional layers on one side and a colored layer with hole-formed regions on the other side, featuring visible light transmittance of 5% or more, along with an irradiation unit or display panel facing the hole-formed region to enhance scratch resistance and seamlessness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a decorative sheet with transmission portions is provided on the cover material surface, then designability is improved, but scratch resistance deteriorates
Solution Approach 1:
The invention moves the decorative pattern from the outermost surface to an inner layer (colored layer), utilizing the depth dimension of the glass laminate structure. The glass substrate serves as a protective outer layer while the colored layer with holes containing light-shielding material provides the decorative function, thus protecting the decorative surface from scratches.
2Illumination intensity
If transmission portions are formed in the pattern portion, then image visibility is improved, but seamlessness deteriorates due to visible boundaries
Solution Approach 1:
The invention applies different properties to different regions: the colored layer has holes in specific regions (corresponding to display areas) allowing light transmission for image visibility, while the light-shielding material within the holes provides local contrast. This local differentiation achieves both image visibility and visual seamlessness.

AI summary
Provided is a glass laminate including: a glass substrate having a first main surface and a second main surface; a functional layer provided on a first main surface side of the glass substrate and including any one or more selected from an antiglare layer, an antireflection layer, and an anti-finger print layer; and a colored layer provided on a second main surface side of the glass substrate and having a hole-formed region in which a plurality of holes are provided, in which the hole-formed region has a visible light transmittance of 5% or more.
