Display Panel Notch Segmentation for Narrow Border and High Screen Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to design display panels and devices with a narrow border and high screen ratio for improved user experience in portable electronic devices, particularly in smart wearable devices, while maintaining high resolution and wide view angles.
Innovation Solution
The display panel features a display region with notches and connection lines that recess inward, allowing data lines to be separated by notches, reducing the space occupied by connection lines in the non-display region and enabling a narrower notch non-display region, while maintaining signal transmission and light-emitting unit arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display panel uses a conventional design without notches, then the border area is wider and provides more space for connection lines, but the screen ratio is lower and the display area is reduced
Solution Approach 1:
The display panel is segmented by introducing notches that divide the non-display region into distinct areas. These notches segment the connection lines into separate groups, allowing them to be routed through different paths and reducing the complexity of the overall connection line layout while maintaining a high screen ratio.
Solution Approach 2:
The design transitions from a conventional rectangular border to a notched configuration that utilizes the vertical dimension more effectively. By creating notches that extend into the non-display region, the design adds dimensional complexity to the border structure, enabling more efficient routing of connection lines and increasing the display area.
2Area of stationary object
If connection lines are routed through the non-display region without notches, then the layout is simpler, but the non-display region occupies more space reducing the screen ratio
Solution Approach 1:
The notches segment the non-display region into multiple zones, allowing connection lines to be routed through specific designated areas rather than across the entire non-display region. This segmentation reduces the overall space required for connection line routing while maintaining manufacturability through standardized routing patterns.
Solution Approach 2:
The notches act as intermediary structures that facilitate the transition of connection lines from the display region to the non-display region. These notched structures provide dedicated pathways that simplify the routing process compared to conventional designs, making the manufacturing process more manageable despite the increased display area.
3Area of stationary object
If notches are introduced to reduce the non-display region space, then the screen ratio increases, but the data lines need to be separated and reconnected increasing manufacturing complexity
Solution Approach 1:
The notches segment the data lines into distinct sections that can be independently managed and connected. By creating controlled segmentation points at the notch locations, the design allows for precise connection points that are easier to manufacture with high precision compared to continuous data line routing across the entire display panel.
Solution Approach 2:
The notch structures are designed and positioned in advance during the manufacturing process, establishing predetermined connection points for the data lines. This preliminary action of creating the notch geometry before data line routing ensures that connections are made at optimized locations, improving manufacturing precision and reducing the complexity of data line reconnection.

AI summary
Display panel and display device are provided. The display panel includes a display region; a non-display region; and a notch. Data lines are disposed in the display region. An edge of the display panel recesses toward the display region to form the notch. The display region includes a first display region and second display regions. The notch and the first display regions are disposed between two second display regions in the first direction and are adjacent in the second direction. The data lines include first data lines in each of the second display regions separated by the notch. Connection lines are disposed surrounding the at least one notch, and each connection line connects two of the first data lines in a same column and on two sides of the notch At least a portion of the connection lines includes first segments disposed in the first display region.
