Solution Overview
Problem
Current display devices with conductive metal frames or black ink coatings create a visible border that affects the aesthetics and comfort of the human-computer interface, particularly as image quality demands increase.
Innovation Solution
A display panel design featuring a light guide element with optical components that refract light to display images in the margin area, reducing the visibility of the frame boundary, using semi-transparent or transparent conductive materials for wiring, and concave-convex structures to prevent total reflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If frames are designed with conductive metals or black ink coating to ensure signal transmission and prevent circuit lines from being visible, then signal transmission effectiveness and circuit line invisibility are improved, but the frame boundary becomes visible and affects aesthetics
Solution Approach 1:
The patent uses transparent or semi-transparent conductive materials instead of traditional black ink coating or opaque metals. This allows the frame area to maintain electrical conductivity while becoming visually transparent, enabling images to be displayed in the margin regions and eliminating the visible frame boundary that previously affected aesthetics.
Solution Approach 2:
The patent employs composite material structures including transparent conductive oxides (such as ITO), nano-silver networks, or graphene combined with light guide elements. These composite materials provide both the required electrical conductivity for signal transmission and optical transparency to eliminate the visible frame boundary, resolving the contradiction between reliability and aesthetics.
2Reliability
If frames are designed with conductive metals to ensure signal transmission, then signal transmission effectiveness is improved, but the frame boundary delimits the image and affects aesthetics
Solution Approach 1:
The patent transitions from opaque to transparent/semi-transparent materials in the frame region, changing the optical properties while maintaining electrical conductivity. This allows the frame to no longer generate the harmful visual delimitation effect, while still ensuring reliable signal transmission through the transparent conductive materials.
Solution Approach 2:
The patent introduces light guide elements as intermediary components in the frame region. These elements serve as mediators that both guide light to enable image display in margin areas and provide structural support for the transparent conductive materials, thereby eliminating the harmful frame boundary delimitation while maintaining signal transmission functionality.
3Object-generated harmful factors
If black ink coating is applied to frames to make circuit lines invisible, then circuit line invisibility is improved, but the frame boundary becomes visible and affects aesthetics
Solution Approach 1:
The patent replaces black ink coating with transparent or semi-transparent conductive materials. This color change from opaque black to transparent allows both circuit lines and frame boundaries to become invisible, as light can pass through these materials without being absorbed or reflected, thereby eliminating both harmful visual effects simultaneously.
Solution Approach 2:
The patent uses composite material structures such as transparent conductive oxide layers combined with ultra-fine metal networks or nanomaterials. These composites provide the necessary electrical conductivity to replace black ink coating for circuit line invisibility, while their transparent nature eliminates the frame boundary visibility problem that black ink coating caused.
4Strength
If a visible physical frame structure is used, then structural support is provided, but the aesthetics and comfort degree of the human-computer interface are affected
Solution Approach 1:
The patent employs thin film structures for transparent conductive materials and light guide elements that can provide adequate structural support while being visually transparent. These thin films maintain the necessary mechanical strength and structural integrity while eliminating the visible frame boundary, thereby improving human-computer interface comfort and aesthetics without sacrificing structural support.
