Display Wiring Layout With T-Shaped Lines for Narrow Bezels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices face challenges in minimizing the space occupied by gate lines and data lines in the non-display area, particularly due to their vertical configuration, which hinders the trend of making electronic devices lighter, thinner, and smaller.
Innovation Solution
The electronic device employs a T-shaped wire structure where gate driving wires and data signal wires are aligned in the same direction, allowing the data driver and gate driver to be arranged on the same side, thereby reducing the frame area. Additionally, dummy signal lines are used to reduce optical unevenness, and a second conductive line covers the through hole to address voltage differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If gate lines and data lines are arranged in different directions (vertical configuration), then electrical connection between gate and data is achieved, but the space occupied in the border area of the non-display area increases
Solution Approach 1:
The patent merges the gate driving wires and data signal wires into the same directional arrangement (both extending in the first direction), allowing the data driver and gate driver to be positioned on the same side. This consolidation reduces the overall frame area compared to traditional vertical configurations where gate and data lines extend in perpendicular directions.
Solution Approach 2:
The patent introduces a T-shaped wire structure where gate driving wires extend in the first direction and data signal wires extend in the second direction (perpendicular to the first direction) to connect to the gate lines. This dimensional reorganization allows drivers to be positioned on the same side while maintaining proper electrical connections, effectively reducing the border area occupation.
2Area of stationary object
If gate lines and data lines are arranged in the same direction to reduce frame area, then frame area is reduced, but optical unevenness increases due to wiring structures and voltage differences
Solution Approach 1:
The patent introduces dummy signal lines as intermediary elements that extend in the first direction parallel to the gate driving wires. These dummy lines act as mediators to balance the voltage distribution and reduce optical unevenness caused by the T-shaped wiring structure, without increasing the frame area since they are positioned within the existing wiring layout.
Solution Approach 2:
The dummy signal lines are electrically connected to the gate driving wires through through holes, creating equipotential regions that balance the voltage distribution across the display panel. This equipotential design compensates for voltage differences in the T-shaped structure, reducing the optical unevenness while maintaining the reduced frame area configuration.
