Innovation Solution
The display apparatus includes a substrate with a display region and a peripheral region, featuring a scan driver layer interposed between the substrate and the display layer, with the scan driver located within the display region's side portion and a dummy scan driver at its center, utilizing dummy clock lines to minimize the peripheral area while maintaining high-quality image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the scan driver is located in the peripheral region outside the display region, then the image quality in the display region is maintained, but the peripheral region area becomes large
Solution Approach 1:
The scan driver is moved from the traditional peripheral region (2D plane outside display region) into the display region itself, specifically positioned in the side portion. This spatial reconfiguration resolves the contradiction by eliminating the need for a large peripheral region while maintaining image quality through careful positioning that avoids interference with display elements.
Solution Approach 2:
The scan driver is nested within the display region's side portion, utilizing the available space inside the display boundaries. This nesting approach allows the scan driver to coexist with the display elements without requiring additional peripheral space, thereby reducing the overall peripheral region area while maintaining functional performance.
2Area of stationary object
If the peripheral region area is reduced to minimize device size, then the device compactness is improved, but the image quality in the display region deteriorates
Solution Approach 1:
By relocating the scan driver into the side portion of the display region rather than keeping it in the peripheral region, the invention achieves compactness without sacrificing image quality. The positioning in the side portion ensures that the scan driver does not interfere with the central display area where image quality is most critical.
Solution Approach 2:
The scan driver is specifically positioned in the side portion of the display region, utilizing a local area that does not compromise the overall image quality. This localized placement allows the rest of the display region to maintain high image quality while the scan driver occupies a specific zone where its presence does not degrade performance.
3Area of stationary object
If the scan driver is positioned in the side portion of the display region, then the peripheral region area is minimized, but the positioning precision and layout complexity increase
Solution Approach 1:
The scan driver is repositioned from the peripheral region to the side portion within the display region, achieving area minimization. The side portion positioning provides a well-defined spatial reference that simplifies manufacturing alignment, as it can be precisely located relative to the display region boundaries without requiring complex peripheral region coordination.
