Static Electricity Prevention Pattern for Display Gate Signal Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquid crystal displays are susceptible to display inferiority due to the influence of static electricity on signal lines, which existing technologies have not effectively addressed.
Innovation Solution
A display device with a first substrate featuring a display area and a non-display area, including gate signal lines, a connection electrode, and a static electricity prevention pattern on the non-display area to reduce or prevent static electricity interference, where the static electricity prevention pattern includes a metal pattern with an upper and lower portion spaced apart and connected by a side portion, and an encapsulation layer fills the space between these components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If gate signal lines are arranged in the non-display area to simplify manufacturing, then manufacturing complexity is reduced, but static electricity interference on signal lines increases causing display inferiority
Solution Approach 1:
A static electricity prevention pattern is introduced as an intermediary element between the gate signal lines and the external environment. This pattern acts as a mediator that intercepts and dissipates static electricity before it can interfere with the signal lines, thereby protecting the signals while maintaining the simplified single-substrate manufacturing structure
Solution Approach 2:
The invention converts the harmful static electricity into a beneficial effect by using the static electricity prevention pattern to actively manage and dissipate charged particles. Instead of letting static electricity accumulate and cause interference, the pattern provides a controlled path for discharge, transforming a harmful factor into a manageable element that protects the display device
2Reliability
If connection electrode connects gate signal lines in different layers, then signal transmission is improved, but exposure to static electricity increases
Solution Approach 1:
The static electricity prevention pattern is strategically positioned at specific locations where connection electrodes expose signal lines to static electricity. By applying protective measures only at these critical local points rather than uniformly across the entire structure, the invention maintains signal transmission reliability while minimizing static electricity exposure

AI summary
A display device includes a first substrate including a display area and a non-display area which is outside the display area; a first gate signal line and a second gate signal line each on the non-display area of the first substrate; a connection electrode which is on the non-display area of the first substrate and connects the first gate signal line and the second gate signal line to each other; and a static electricity prevention pattern which is on the non-display area of the first substrate and on the connection electrode.
