Solution Overview
Problem
Display devices face challenges in reducing crosstalk between gate lines and transmitting lines, which affects display quality and resolution.
Innovation Solution
The display device incorporates a specific arrangement of pixel structures with overlapping patterns, including a substrate, active patterns, gate lines, connecting patterns, and transmitting lines, along with a shielding pattern to prevent or reduce crosstalk, thereby improving display quality and resolution.

Engineering Contradiction Analysis
1Manufacturing precision
If gate lines and transmitting lines are arranged in overlapping configurations to improve resolution and reduce dead space, then display resolution and space utilization are improved, but crosstalk between lines increases affecting display quality
Solution Approach 1:
A shielding pattern is introduced as an intermediary element between the gate line and transmitting line. This shielding pattern acts as a mediator that blocks or reduces the electromagnetic coupling (crosstalk) between the two lines while allowing them to maintain their overlapping arrangement for improved resolution and space utilization.
Solution Approach 2:
The harmful crosstalk effect is converted into a beneficial shielding effect by strategically placing conductive shielding patterns at specific locations. These patterns utilize the same electromagnetic field interactions that cause crosstalk but redirect them to protect sensitive signal lines, turning the harmful phenomenon into a protective mechanism.
2Object-generated harmful factors
If shielding patterns are added to reduce crosstalk, then display quality is improved, but device complexity and manufacturing steps increase
Solution Approach 1:
The shielding pattern is merged with existing structural elements of the display device, such as integrating it with the gate line structure or utilizing existing conductive layers. This combining approach reduces the need for separate, standalone shielding components and simplifies the overall manufacturing process.
Solution Approach 2:
The shielding pattern serves multiple functions simultaneously: it provides crosstalk reduction, acts as an additional conductive interconnect, and can serve as an electrostatic discharge protection layer. This multi-functionality reduces the need for separate dedicated shielding structures, thereby reducing overall device complexity.
