Window Member Curved Light Shielding Pattern Reduces Bezel Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window members in electronic apparatuses have a significant bezel area that obstructs the display and signal transmission, limiting the design flexibility and user preference for wider display areas with narrower bezels.
Innovation Solution
A window member with a light shielding pattern featuring a narrow width, including a base substrate and a multilayer light shielding layer with curved edges, is designed to create a signal transmission area while minimizing the bezel area, using a manufacturing method that involves forming a preliminary pattern and irradiating specific areas with a laser beam to define the signal transmission area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a conventional light shielding pattern is used in the window member, then the structural integrity and light shielding function are maintained, but the bezel area becomes large which obstructs the display and signal transmission
Solution Approach 1:
The light shielding pattern incorporates curved portions along its edges instead of straight lines. These curved portions allow the pattern to maintain structural integrity while reducing the overall bezel area, enabling signals to pass through more efficiently while still providing adequate light shielding functionality.
Solution Approach 2:
The light shielding pattern is designed with varying local properties - the curved portions are strategically positioned to provide light shielding where needed while creating openings or reduced density areas that allow signal transmission. This localized variation in quality enables simultaneous achievement of structural integrity and reduced bezel area.
2Area of stationary object
If the light shielding pattern width is increased to maintain shielding effectiveness, then light shielding function is improved, but the bezel area increases and display area is reduced
Solution Approach 1:
By using curved portions in the light shielding pattern, the design achieves effective light shielding with a narrower pattern width. The curved geometry allows light to be blocked more efficiently per unit width compared to straight-line patterns, thereby increasing the display area while maintaining shielding effectiveness.
Solution Approach 2:
The curvature radius and pitch of the curved portions are optimized to achieve the desired light shielding effectiveness with minimal width. By adjusting these parameters, the pattern blocks light effectively while minimizing the bezel area and maximizing the display area.
3Area of stationary object
If the light shielding pattern is designed with straight edges for simplicity, then manufacturing is easier, but the signal transmission area is reduced and design flexibility is limited
Solution Approach 1:
The curved portions in the light shielding pattern are designed with standardized curvature radii and pitches that can be efficiently manufactured using modern fabrication techniques such as laser cutting or precision molding. This approach maximizes signal transmission area while maintaining ease of manufacture through standardized curved geometries.

AI summary
A window member including a base substrate and a light shielding layer including a first light shielding pattern disposed in a first area of the base substrate and a second light shielding pattern disposed in a second area of the base substrate while being spaced apart from the first light shielding pattern and providing a signal transmission area at an inner side thereof. The second light shielding pattern includes an edge having a plurality of curved portions on a plane. This arrangement reduces an area of the light shielding pattern adjacent to the signal transmission area of the window member.
