Array Substrate Arc Layout for Narrow-Bezel Display Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels face challenges in reducing the area of the non-display region, particularly the bezel, to accommodate the increasing demand for narrow bezels in electronic devices without increasing the complexity of circuit arrangements.
Innovation Solution
The array substrate design includes a substrate with a display region and a non-display region, featuring signal lines, circuit modules, and fan-out lines, where circuit modules are arranged in an arc-shaped third sub-region, reducing the number of wirings and allowing for a more compact and uniform arrangement, thereby minimizing the bezel area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If circuit modules are arranged in traditional linear or step patterns in the non-display region, then the circuit connections are straightforward, but the area of the non-display region (bezel) becomes larger
Solution Approach 1:
The patent applies curvature by arranging circuit modules along an arc-shaped path in the non-display region rather than using traditional linear or stepped patterns. This arc-shaped arrangement allows the circuit modules to be positioned more compactly, reducing the overall area occupied by the non-display region while maintaining proper electrical connections through fan-out lines that extend from the arc-shaped arrangement to the display region.
Solution Approach 2:
The patent transitions from two-dimensional linear or stepped arrangements to a curved one-dimensional path that effectively utilizes the available space in the non-display region. By arranging circuit modules along an arc, the design exploits the radial dimension of the bezel area, allowing for more efficient space utilization and reduced bezel area compared to conventional planar arrangements.
2Area of stationary object
If the number of wirings in the non-display region is reduced, then the area of the non-display region is reduced, but the electrical connection reliability may be compromised
Solution Approach 1:
The patent merges multiple signal line connections into a compact arc-shaped arrangement where circuit modules positioned along the arc can share common fan-out lines. This merging of connection paths reduces the total number of wirings required in the non-display region while maintaining reliable electrical connections, as each circuit module remains properly connected to the display region through the optimized fan-out line structure.

AI summary
An array substrate and a display panel. The array substrate includes: a substrate having a display region and a non-display region surrounding the display region. The non-display region includes a first sub-region extending in a first direction, a second sub-region extending in a second direction, and a third sub-region connecting the first sub-region with the second sub-region, and the third sub-region extends in an arc shape, and the first sub-region comprises a binding region; a plurality of signal lines extending in the display region; a plurality of circuit modules located on the substrate; and a plurality of fan-out lines located in the non-display region. Each of the fan-out lines is electrically connected to a corresponding one of the circuit modules and extends to the binding region.
