GOA Circuit Layout for Near Bezel-Free Display Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current GOA circuit designs occupy significant layout space on display panels, limiting the ability to further reduce bezel sizes, especially in applications requiring ultra-narrow bezels.
Innovation Solution
The design of a GOA circuit within the display area of an array substrate, where the GOA circuit is modularly designed and staggered between pixel units in adjacent rows, reducing the layout space occupied and improving design efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If GOA circuits are placed on both sides of the display panels, then the bonding processes in the row scan line direction are eliminated and integration is improved, but the layout space occupied increases and prevents further bezel size reduction
Solution Approach 1:
The patent transitions from placing GOA circuits on the side edges of the display panel to embedding them within the display area, utilizing the vertical dimension and inter-pixel spacing. This dimensional repositioning allows the GOA circuits to be integrated without increasing the horizontal bezel width, thereby resolving the contradiction between manufacturing integration and layout space occupation.
Solution Approach 2:
The GOA circuits are nested within the display area by positioning them in the gaps between adjacent pixel units. This nesting approach allows the driving circuits to be housed within the existing display structure without requiring additional external space, thus maintaining compact bezel dimensions while achieving circuit integration.
2Area of stationary object
If GOA circuits are designed to occupy minimal layout space, then bezel sizes can be reduced, but the complexity of circuit design and layout increases
Solution Approach 1:
The display area is segmented into pixel units with intervening gaps, and the GOA circuits are assigned to specific segments (gaps between pixels). This segmentation allows the circuits to be distributed throughout the display area rather than concentrated in one location, reducing the required bezel space while managing design complexity through modular placement.
Solution Approach 2:
Different regions of the display area are assigned different functions: pixel units for display and gaps between pixels for GOA circuits. This local differentiation optimizes space utilization by placing circuits only where needed, minimizing overall layout space requirements while maintaining design organization and reducing complexity through functional zoning.

AI summary
An array substrate and a display panel are disclosed; at least one GOA circuit is provided in a pixel area of a same row, all GOA circuits of the same row are connected to a same scan line, and each GOA circuit of the same row is connected to a driving IC through a corresponding driving signal line. By setting the GOA circuit in a display area, a near bezel-free display panel design can be realized. Meanwhile, the GOA circuit is modularly designed to form an independent layout model, which improves design efficiency.
