Display Panel Segmented Fanout Layout for Narrow Lower Borders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies face challenges in achieving a 100% screen-to-body ratio due to limitations in reducing the size of the lower border of display panels, as the size of the lower border is often larger compared to the left and right borders, making it difficult to further minimize the width of the data line fanout area.
Innovation Solution
The implementation of a segmented fanout mode for data lines, where the data lines are distributed across multiple fanout sub-areas and power lines are used as intervals between these sub-areas, effectively reducing the width of the fanout area and thereby minimizing the lower border size, while maintaining the same resolution and design specifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If data lines are concentrated in a single fanout area, then wiring is simplified, but the lower border width increases
Solution Approach 1:
The patent divides the fanout area into multiple fanout sub-areas (first fanout sub-area, second fanout sub-area, third fanout sub-area) and distributes different groups of data lines across these sub-areas. This segmentation reduces the concentration of wiring in any single location, thereby reducing the overall lower border width while maintaining organized wiring structure.
2Length of stationary object
If the lower border width is reduced, then screen-to-body ratio increases, but wiring space becomes insufficient
Solution Approach 1:
The patent extends data lines not only in the horizontal direction but also in the vertical direction by utilizing multiple fanout sub-areas arranged in different dimensions. Data lines are distributed across first, second, and third fanout sub-areas located at different positions, effectively using two-dimensional space distribution to accommodate all wiring within a reduced overall border width.
3Length of stationary object
If data lines are distributed across multiple fanout sub-areas, then lower border width is reduced, but device complexity increases
Solution Approach 1:
The patent combines multiple fanout sub-areas (first, second, and third fanout sub-areas) into a unified fanout structure that collectively accommodates all data lines. By merging these sub-areas with coordinated data line groups, the design achieves compact wiring distribution that reduces border width while maintaining manageable structural complexity through systematic organization.
