Cover Glass With Pattern Layer Holes For Self-Luminous Effect
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cover glasses for electronic devices limit design customization and aesthetically pleasing appearances due to their material characteristics and printing methods, making it difficult to maximize display area and differentiate devices visually.
Innovation Solution
A cover glass structure featuring a transparent substrate with a pattern layer, a color layer, and a light reflection layer, where the pattern layer includes holes and the color layer is positioned between the pattern and reflection layers, allowing natural light to pass through and reflect, creating a self-luminous effect without a separate light-emitting unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional glass material and printing method are used for the cover window, then the surface hardness and optical performance are improved, but the design customization and aesthetically pleasing appearance are limited
Solution Approach 1:
The cover glass is divided into multiple functional layers: a transparent substrate layer, a pattern layer with reflective regions, and a color layer. This segmentation allows each layer to perform its specific function while enabling design customization through the combination of layers, resolving the contradiction between maintaining glass strength and achieving design versatility.
Solution Approach 2:
The invention uses a composite structure combining transparent glass substrate, pattern layer with reflective properties, and color layer. This composite material approach allows the cover glass to maintain the strength of glass while incorporating design elements through the pattern and color layers, achieving both structural integrity and design customization.
2Area of stationary object
If the display area is maximized with a front display design, then the visual performance is improved, but the design differentiation and aesthetically pleasing appearance become more difficult to achieve
Solution Approach 1:
The pattern layer is applied selectively to specific regions of the cover glass, such as the bezel areas or specific design zones, while leaving other areas transparent. This local application of reflective and colored patterns allows the display area to be maximized while still providing design differentiation in strategic locations.
Solution Approach 2:
The color layer is used to introduce various colors and visual effects to specific regions of the cover glass. By applying different colors to different areas, the invention enables design differentiation and aesthetic appeal while maintaining a large display area, as the color effects are concentrated in non-display regions.
3Illumination intensity
If a separate light-emitting unit is added to achieve self-luminous effect, then the visual appeal in dark environments is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The pattern layer with reflective regions and the color layer work together to create a self-luminous effect using ambient light. The reflective regions reflect light to create bright areas, while the color layer provides coloration, eliminating the need for separate light-emitting units and reducing device complexity while maintaining visual appeal.
Solution Approach 2:
The invention replaces the mechanical/electrical light-emitting system with an optical system using reflective regions and color layers. By using light reflection and color perception instead of active light emission, the device complexity is reduced while achieving similar visual effects in appropriate lighting conditions.

Function Achieved in This Case
This solution enables design differentiation and aesthetically pleasing appearances by exhibiting colors in the presence of natural light, while appearing black in its absence, without mixing the materials of the color and mirror layers, thus enhancing the visual appeal of electronic devices.
Implementation Method 1
a light reflection layer formed beneath the pattern layer and including a reflecting surface facing the pattern layer, and a color layer having a second color different than the first color, the color layer being formed between the pattern layer and the light reflection layer, wherein the reflecting surface is formed such that light reflected on the reflecting surface passes through the color layer and at least a portion of the one or more holes
