Solution Overview
Problem
Conventional display panels have low light transmittance due to wires blocking light, affecting the operational yield of photosensitive modules.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If wires are arranged in conventional planar layout on the substrate, then electrical connectivity is achieved, but light transmittance is reduced due to increased wire blocking area
Solution Approach 1:
The patent transitions from a two-dimensional planar wire layout to a three-dimensional stacked wire configuration. Multiple wires are stacked vertically along the thickness direction (z-axis) at overlapping positions, allowing orthographic projections to coincide. This vertical stacking reduces the horizontal footprint of wires, thereby increasing the light-transmitting area of the display panel while maintaining all necessary electrical connections.
2Illumination intensity
If multiple wires are stacked vertically to reduce projection area, then light transmittance increases, but wire insulation and signal interference management becomes more complex
Solution Approach 1:
The patent introduces insulating layers as intermediary structures between stacked wires to prevent electrical short circuits. These insulating layers are positioned at intervals between adjacent wires in the vertical stacking sequence, serving as mediators that enable close vertical proximity while maintaining electrical isolation. This allows the wire stacking configuration to achieve both space efficiency and electrical safety.
Solution Approach 2:
The patent extracts and separates signal lines from power supply lines in the vertical stacking arrangement. By taking out different types of wires into separate stacking groups, the design reduces mutual interference between signal and power lines. This extraction strategy allows optimized routing and insulation placement, simplifying the overall insulation structure while maintaining functionality.
3Reliability
If shielded wires are added between signal lines to reduce interference, then signal quality improves, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent employs shielded wire structures as intermediary elements positioned between adjacent signal lines in the vertical stack. These shielded wires act as mediators that block electromagnetic interference between signal lines while maintaining the compact stacked configuration. The shielded wires are integrated into the existing wire stacking process, adding interference protection without requiring separate manufacturing steps.

AI summary
The present application discloses a display panel and a display apparatus. The display panel includes a first display region. The first display region includes a first region. The display panel includes: a substrate and a plurality of wires located on the substrate. The first region includes at least one wire region, and the plurality of wires in the at least one wire region are stacked and insulated along a direction perpendicular to the substrate. According to the display panel provided in the present application, since the wires in the wire region are stacked along the direction perpendicular to the substrate, orthographic projections of the wires in the wire region on the substrate at least partially overlap, making an orthographic projection area of the wire region on the substrate smaller.
