Display Panel Data-Line Routing for Narrower Lower Bezels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses face challenges in achieving higher screen-to-body ratios as they become thinner and lighter, necessitating improvements in display panel design to expand the display region.
Innovation Solution
The display panel design includes a display region surrounding a functional device configuration region, with data lines arranged in specific patterns and additional wirings that redirect signal transmission, reducing the need for direct connections at the edges and optimizing wiring space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If data lines are directly connected to edges of the display panel, then electrical signal transmission is simplified, but the lower frame width increases reducing the screen-to-body ratio
Solution Approach 1:
The patent introduces intermediate wirings that extend data lines from the display region through the functional device configuration region to the lower frame. This dimensional extension allows signal transmission without requiring wider edge connections, thereby maintaining screen-to-body ratio while ensuring electrical connectivity.
Solution Approach 2:
The patent employs intermediate wirings as mediators between the display region and the lower frame. These wirings route signals through the functional device configuration region, eliminating the need for direct edge connections and reducing the lower frame width requirement.
2Area of moving object
If the display region is expanded to increase screen-to-body ratio, then the display area increases, but the wiring space for data lines becomes constrained
Solution Approach 1:
The patent segments the wiring path into multiple sections: data lines in the display region, intermediate wirings through the functional device configuration region, and connections to the lower frame. This segmentation allows efficient space utilization by distributing wiring across different regions rather than concentrating all wiring in the display area.
Solution Approach 2:
The patent utilizes the vertical dimension by extending wirings from the display region through the functional device configuration region down to the lower frame. This three-dimensional wiring approach maximizes the use of available space without compromising the display area.
3Area of moving object
If additional wirings are added to redirect signal transmission, then the screen-to-body ratio increases, but the fabrication complexity increases
Solution Approach 1:
The intermediate wirings serve multiple functions: they extend data lines from the display region, pass through the functional device configuration region, and connect to the lower frame. This multi-functionality reduces the need for separate dedicated wiring paths, thereby simplifying the overall fabrication process despite the increased screen-to-body ratio.
