Solution Overview
Problem
Current display devices face challenges in manufacturing transparent displays without forming dead zones, which restrict design flexibility and increase costs due to the integration of wiring substrates and printed circuit boards.
Innovation Solution
A display device configuration featuring a display panel with routing lines on its outer surface, a wiring substrate connected to these lines, and a separate printed circuit board, allowing signal input and distribution without forming dead zones, thus enabling the production of transparent displays as islands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wiring substrate and printed circuit board are integrated together, then signal transmission is achieved, but dead zones are formed that restrict design flexibility and increase manufacturing costs
Solution Approach 1:
The patent divides the wiring substrate into multiple independent wiring regions, each capable of being transparent or opaque. This segmentation allows different portions of the display device to have different optical properties, enabling transparent display functionality in specific areas while maintaining structural integrity and signal transmission capabilities in other areas, thereby eliminating dead zones and improving design flexibility
Solution Approach 2:
The patent applies different optical characteristics to different regions of the wiring substrate. Specific wiring regions are designed to be transparent to light in certain wavelength ranges, while other regions remain opaque. This local differentiation allows the display device to achieve transparent display effects in designated areas without compromising the overall structural function, thus eliminating the need for dead zones
2Ease of manufacture
If wiring substrate and printed circuit board are integrated together, then signal transmission is achieved, but manufacturing costs increase
Solution Approach 1:
By segmenting the wiring substrate into functional regions with different optical properties, the patent simplifies the manufacturing process. Each wiring region can be independently optimized and manufactured using appropriate materials and processes, reducing the need for complex integration of separate transparent and opaque components, thereby lowering manufacturing costs while maintaining signal transmission functionality
