Display Panel Corner Expansion via Substrate Slits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses have limited expandability of the display area, particularly at corner portions, due to the constraints of non-display areas and the difficulty in arranging pixels and drivers in these areas.
Innovation Solution
The display apparatus incorporates a substrate with slits cut towards the corner, allowing for a strip portion between slits where additional display areas can be expanded, including a second display area at the corner and a third display area between the first and second display areas, with adjustable pixel spacing and integrated drivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display area is expanded to include corner portions, then the overall display area increases, but the structural complexity and difficulty of arranging pixels and drivers increases
Solution Approach 1:
The display panel is divided into multiple display areas (first display area, second display area at corner, third display area between them) with distinct pixel arrangements. The substrate is segmented with slits to create separate regions that can be independently optimized, allowing complex corner geometry to be managed as modular sections rather than a monolithic structure.
Solution Approach 2:
Different display areas have different characteristics optimized for their specific functions. The first display area uses standard pixel arrangements, while the second display area at the corner uses a different arrangement suited for corner geometry. The third display area bridges these regions with transitional characteristics, allowing each local region to have optimal properties for its position.
2Area of stationary object
If pixels are arranged in corner portions with slits, then the display area is expanded, but the manufacturing precision required increases
Solution Approach 1:
The slits are pre-formed in the substrate at defined positions and orientations before pixel arrangement. This preliminary structuring of the substrate creates predetermined locations and geometric constraints that guide subsequent pixel placement, ensuring precise alignment without requiring high-precision positioning during the pixel arrangement process itself.
Solution Approach 2:
The slits are arranged asymmetrically with different orientations in different regions (first slits in first region, second slits in second region). This asymmetric arrangement creates naturally distinct zones that simplify pixel positioning, as each zone has its own reference geometry rather than requiring uniform precision across the entire panel including corners.
3Area of stationary object
If the non-display area is reduced by integrating drivers in the third display area, then the display area increases, but the stress concentration during deformation increases
Solution Approach 1:
The third display area serves as an intermediary region between the first and second display areas. It contains drivers that mediate the electrical connection between pixels in different display areas, allowing the drivers to be integrated within the display region rather than in separate non-display areas. This intermediary structure distributes stress more evenly across the panel during deformation.
Solution Approach 2:
The driver integration utilizes the third display area as an additional spatial dimension for accommodating circuitry. Instead of confining drivers to peripheral non-display areas, the invention uses the intermediate region between corner and main display areas, effectively utilizing unused space in a different dimensional arrangement to reduce stress on corner structures.

AI summary
A display panel includes a substrate, a first display area including first pixels, a second display area located at a corner of the first display area and including second pixels, a third display area located between the first display area and the second display area and including third pixels, first display units, second display units, and third display units, which are disposed on the substrate and correspond to the first to third pixels, respectively, and a driver which provides the first to third display units with an electrical signal, and having a portion of which overlaps the third pixels. Slits cut in a direction toward a corner of the substrate from an inner side of the substrate is defined in the substrate at the corner thereof, and the substrate includes a strip portion between two adjacent slits.
