Cover Window Light-Blocking Pattern for Flexible Display Wiring Concealment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing variable display apparatuses face issues with wiring visibility and reflected light, which detract from user immersion and increase thickness due to the limitations of polarizers and decoration films in flexible structures.
Innovation Solution
Incorporating a light-blocking pattern into the cover window of the display apparatus to conceal connection wirings and reduce thickness by integrating it with the cover window, thereby omitting polarizers and decoration films.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If polarizers and decoration films are used to hide connection wirings, then wiring visibility is improved, but device thickness increases
Solution Approach 1:
The patent combines the light-blocking function with the cover window structure by forming a light-blocking pattern directly on the cover window substrate. This integration eliminates the need for separate polarizer and decoration film layers, achieving wiring concealment while reducing overall device thickness.
Solution Approach 2:
The cover window is designed to serve multiple functions: it provides structural protection, maintains display brightness, and conceals connection wirings through an integrated light-blocking pattern. This multi-functionality eliminates the need for separate dedicated components.
2Object-affected harmful factors
If multiple layers (polarizer, decoration film) are added to hide wirings, then wiring visibility is improved, but device complexity increases
Solution Approach 1:
The patent merges the light-blocking pattern directly into the cover window structure, reducing multiple separate layers (polarizer, decoration film) into a single integrated component. This simplification maintains wiring concealment while reducing structural complexity.
3Adaptability or versatility
If flexible wiring structure is used for variable display, then adaptability is improved, but wiring visibility worsens
Solution Approach 1:
The patent combines the flexible cover window with an integrated light-blocking pattern, allowing the wiring to remain flexible for variable display applications while the patterned cover window conceals the wiring from view.
