Engineering Contradiction Analysis
1Area of moving object
If vertical signal lines are placed close to each other to reduce layout area, then area efficiency improves, but signal interference between adjacent vertical signal lines increases
Solution Approach 1:
A shielding wire is introduced as an intermediary element positioned between adjacent vertical signal lines. This shielding wire acts as a mediator that blocks electromagnetic interference between the vertical signal lines while allowing the lines to remain closely spaced, thus reducing layout area without compromising signal quality.
Solution Approach 2:
The space between adjacent vertical signal lines is segmented by introducing a shielding wire. This segmentation creates separate electromagnetic zones around each vertical signal line, preventing interference while maintaining compact layout. The shielding wire divides the problematic continuous space into controlled segments.
2Reliability
If shielding wires are added between vertical signal lines to reduce signal interference, then signal quality improves, but device complexity increases
Solution Approach 1:
The shielding wire is merged with the existing pixel structure layout, where it serves dual purposes: providing electromagnetic shielding between vertical signal lines and maintaining structural alignment with the pixel array. This merging approach adds shielding functionality without proportionally increasing overall device complexity.
3Adaptability or versatility
If the display region uses non-rectangular contours to achieve design flexibility, then adaptability improves, but layout design difficulty increases
Solution Approach 1:
The shielding wire structure is designed with universal applicability, where the same shielding principle can be applied regardless of the specific non-rectangular contour shape. The shielding wires can be adapted to follow various boundary shapes while maintaining their interference-blocking function, making the solution versatile for different display geometries.

AI summary
An electronic device includes a substrate, multiple transversal signal lines, a first vertical signal line, a second vertical signal line, a shielding wire, and multiple pixel structures. The first vertical signal line is intersected with the transversal signal lines. The second vertical signal line is intersected with the transversal signal lines and connected to one of the transversal signal lines. An orthogonal projection of the shielding wire on the substrate is located between an orthogonal projection of the first vertical signal line and an orthogonal projection of the second vertical signal line on the substrate. One of the pixel structures is surrounded by a corresponding one of the transversal signal lines and the second vertical signal line and includes an active device. A gate and a source of the active device is electrically connected to the corresponding one transversal signal line and the first vertical signal line respectively.
