Transparent Display Frame Traces with Hollow Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transparent displays have opaque frames that significantly reduce transparency, posing safety risks in applications like vehicle windshields and limiting product yield due to disconnection risks.
Innovation Solution
A transparent display design featuring a substrate with frame traces that include a hollow portion and a conductive portion, where the hollow portion is significantly larger than the conductive portion, arranged in a mesh or diamond shape, and separated by an insulating layer, allowing for high transmittance and reducing the risk of disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If opaque frames are used in transparent displays, then structural integrity and electrical connectivity are improved, but transparency is significantly reduced
Solution Approach 1:
The frame traces are designed with hollow portions creating a porous structure that allows light transmission. The conductive portions are distributed within the hollow portions, maintaining electrical connectivity while minimizing visual obstruction. This porous design enables the frames to be both structurally sound and transparent, resolving the contradiction between structural integrity and transparency.
2Reliability
If frame traces are made with larger conductive portions, then electrical connectivity is improved, but transparency is reduced
Solution Approach 1:
The frame traces employ local quality by concentrating conductive portions specifically within the hollow portions rather than uniformly distributing material throughout. This localized placement of conductive material ensures electrical connectivity is maintained at critical points while minimizing the overall visual obstruction, thus improving electrical connectivity without significantly reducing transparency.
3Ease of manufacture
If traditional frame structures are used, then manufacturing simplicity is maintained, but disconnection risks increase
Solution Approach 1:
The frame traces are segmented into conductive portions and hollow portions, with the conductive portions forming continuous paths through the hollow structures. This segmentation allows for modular manufacturing processes where conductive layers can be deposited independently, reducing manufacturing complexity while ensuring continuous electrical pathways that minimize disconnection risks.

AI summary
The transparent display includes a substrate and a plurality of frame traces. The substrate includes a transparent display region and a frame region defined on a left side, a right side, and an upper side of the transparent display region. The plurality of frame traces are disposed in the frame region, and each frame trace includes a hollow portion and a conductive portion surrounding the hollow portion. B disposing the hollow portion in each frame trace to improve a transmittance of each frame trace, thereby improving a transparency of the frame region, reducing a risk of disconnection, and improving a product yield.
