Display Panel Signal Routing Around Optical Transmission Region
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels face challenges in minimizing the non-display region while maintaining a large display region, as current designs often require significant space for signal lines and circuits, which obstructs the view and reduces the overall display area.
Innovation Solution
The proposed solution involves a display panel configuration with distinct regions, where the signal lines and pixel driving circuits are strategically placed in specific areas, allowing for a smaller non-display region by using a second panel region with higher light transmittance and optimizing the placement of signal lines and circuits in the first and third regions, thereby reducing the overall non-display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the non-display region is reduced to increase display area, then the display region area is improved, but the signal transmission path becomes more complex
Solution Approach 1:
The display panel is divided into a first panel region containing pixel rows and a second panel region that acts as a signal passing region. This segmentation allows signal lines to be routed through the second panel region without interfering with the display area, thus increasing the display region while managing signal transmission complexity through spatial organization.
Solution Approach 2:
Signal lines are routed through the second panel region in a direction perpendicular to the pixel rows, utilizing the vertical dimension of the panel structure. This dimensional approach allows signal transmission without occupying horizontal display space, thereby increasing display area while maintaining signal transmission capability.

If the second panel region is used for optical signal propagation, then the display region area is improved, but the circuit element arrangement becomes more complex
Solution Approach 1:
The signal transmission function is extracted from the first panel region and relocated to the second panel region. This extraction allows the first panel region to be fully dedicated to display elements while the second panel region handles signal routing, thus increasing display area while organizing circuit element arrangement into functional zones.
Solution Approach 2:
The second panel region serves multiple functions: it acts as a signal passing region for optical signals, provides a pathway for signal lines, and maintains structural integrity of the display panel. This multi-functionality allows the region to support both display expansion and circuit routing without requiring additional dedicated spaces.
3Area of moving object
If pixel rows are divided into portions by the second panel region, then the display region area is improved, but the pixel row structure becomes more complex
Solution Approach 1:
Pixel rows are segmented into multiple portions by the second panel region, with each portion independently connected to signal lines. This segmentation allows the display region to expand while the second panel region provides structured pathways for signal distribution to each pixel row portion, managing the complexity through organized spatial arrangement.

AI summary
A display panel including a first panel region (FPR) including (n−1)-th and n-th pixel rows ((n−1)PR and nPR), and a second panel region (SPR) dividing the nPR to propagate an optical signal. The display panel includes a circuit element layer (CEL) and a display element layer (DEL). The CEL includes a signal line (SL), a pixel driving circuit (PDC), and first to third regions. The SL and the PDC are in the first region. The second region (SR) corresponds to the SPR. The SL and the PDC are not in the SR. The third region (TR) corresponds to the SPR and is along a periphery of the SR. The SL is in the TR, and includes an (n−1)-th scan line ((n−1)SL) connected to the (n−1)PR, an n-th reset line (nRL) connected to the nPR, and a first row connection line in the TR and connecting the (n−1)SL and the nRL.
