Display Device Non-Display Area Signal Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to reduce the size of the non-display area in display devices, particularly in organic light-emitting display devices, to minimize the bezel area and enhance appearance characteristics while maintaining efficient signal connectivity to the driver circuit.
Innovation Solution
The solution involves optimizing the layout of signal lines in the non-display area by using a configuration with multiple lines and areas, where connection lines are strategically arranged to reduce space occupancy and intersecting lines are used to minimize the size of the non-display area, allowing for a narrower bezel and improved manufacturing efficiency.

Engineering Contradiction Analysis
1Reliability
If signal lines are disposed in the non-display area to connect to the driver circuit, then electrical connectivity is achieved, but the non-display area size increases
Solution Approach 1:
The patent applies dimensionality change by routing signal lines through multiple layers (first through fourth signal lines in different layers) and using three-dimensional spatial arrangement. The signal lines extend in different directions (first, second, and third directions) and intersect at various heights, transforming a two-dimensional area problem into a three-dimensional space solution, thereby reducing the non-display area footprint while maintaining connectivity.
Solution Approach 2:
The patent segments the signal transmission path into multiple separate signal lines (first, second, third, and fourth signal lines) that can be independently routed through different layers and directions. This segmentation allows each line to be optimized for its specific connection path, enabling more efficient space utilization in the non-display area.
2Reliability
If multiple signal lines are disposed in the non-display area to maintain connectivity, then electrical connection is ensured, but the bezel area increases
Solution Approach 1:
The patent uses three-dimensional spatial arrangement with signal lines extending in multiple directions (first, second, and third directions) and intersecting at different heights. This vertical dimensionality allows multiple signal lines to occupy the same horizontal footprint without interfering with each other, thereby reducing the bezel area while maintaining all necessary connections.
Solution Approach 2:
The patent merges multiple signal lines at intersection points where they cross each other in space. By allowing lines to share common spatial paths and combine their routing functions, the patent reduces the total space required for signal transmission, thereby minimizing the bezel area while ensuring complete connectivity.
