Display Panel Narrow Frame Design via Connection Line Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels face challenges in achieving a narrow frame design due to the large width of the non-display region, which is occupied by signal lines and circuit structures, making it difficult to reduce the frame width effectively.
Innovation Solution
The display panel incorporates a first power signal line and a first connection line, where at least a part of the connection line is located in the display sub-region, and the width of the connection line is smaller than the power signal line, reducing the layout space in the non-display sub-region and facilitating a narrow frame design.

Engineering Contradiction Analysis
1Reliability
If the non-display region is expanded to accommodate signal lines and circuit structures, then the electrical connectivity and power transmission are improved, but the frame width increases
Solution Approach 1:
The patent applies dimensionality change by routing the power signal line through both the non-display region and the display region. Specifically, the power signal line extends from the binding region through the first non-display sub-region, then continues through the first display sub-region to reach the second display sub-region. This multi-dimensional routing allows the signal line to utilize the display region space, thereby reducing the required width of the non-display region while maintaining electrical connectivity.
Solution Approach 2:
The patent segments the power signal transmission path into multiple sections: a first power signal line in the non-display region and a second power signal line in the display region. These segments are electrically connected, allowing the power signal to be transmitted through different regions with different functional requirements, thus optimizing the overall layout.
2Length of stationary object
If the width of the connection line is reduced to save layout space, then the frame width can be narrowed, but the current carrying capacity may be compromised
Solution Approach 1:
The patent applies local quality by differentiating the width of power signal lines in different regions. The first power signal line in the non-display region has a first width optimized for layout constraints, while the second power signal line in the display region has a second width optimized for current carrying capacity. This localized optimization allows each segment to have dimensions appropriate to its specific functional requirements.
Solution Approach 2:
The patent resolves the width contradiction by utilizing the vertical dimension (layer structure) rather than only the horizontal dimension. Different power signal lines are placed in different layers, allowing them to be electrically connected without occupying the same horizontal space. This enables the connection lines to have smaller widths in the horizontal plane while maintaining adequate current carrying capacity through proper layer separation and connection.

AI summary
A display panel and an electronic device are provided. The display panel includes: a substrate, a first power signal line and a first connection line. The substrate includes a display region and a non-display region surrounding the display region, where the display region includes a first display sub-region and a second display sub-region, the non-display region includes a first non-display sub-region and a second non-display sub-region, the first non-display sub-region includes a binding region, and the binding region is opposite to the first display sub-region The first power signal line is located in the second non-display sub-region. The first connection line is electrically connected to a part of the first power signal line, extends to the binding region, and is at least partially located in the first display sub-region. A width of the first connection line is smaller than a width of the first power signal line.
