Light Emitting Substrate Signal Layout for Narrow Display Borders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mini-LED display technology faces challenges in optimizing the layout of signal lines and light emitting units, leading to increased border region width and reduced light emitting region proportion, which affects display efficiency and user experience.
Innovation Solution
The proposed light emitting substrate design includes a specific arrangement of target signal lines with extension, connection, and second extension sections that enclose receiving regions, allowing the second extension section to be partially located in the light emitting region, thereby reducing the border region width and increasing the light emitting region proportion.

If signal lines are arranged in conventional layouts, then signal line connectivity is ensured, but border region width increases and light emitting region proportion decreases
Solution Approach 1:
The signal line is divided into multiple sections: first extension section, connection section, and second extension section. Each section serves a specific function and is positioned in different regions, allowing the signal line to navigate around light emitting units while minimizing border region occupation.
Solution Approach 2:
The signal line layout transitions from a simple linear arrangement to a multi-dimensional configuration that weaves through the light emitting region. The signal line extends in multiple directions and encloses receiving regions, effectively utilizing the two-dimensional space without increasing border width.
2Productivity
If border region width is reduced to increase light emitting region proportion, then display efficiency improves, but signal line routing becomes more difficult
Solution Approach 1:
The signal line structure encloses receiving regions that contain light emitting units, creating a nested configuration. The first extension section, connection section, and second extension section form enclosing structures around groups of light emitting units, allowing efficient space utilization and simplified routing.
Solution Approach 2:
Different sections of the signal line are positioned in different regions with different functional requirements. The first extension section is located in the border region for connection purposes, the connection section navigates through intermediate areas, and the second extension section extends into the light emitting region, with each section optimized for its specific location.
