Engineering Contradiction Analysis
1Adaptability or versatility
If pixel regions are spaced apart with non-pixel regions, then device layout flexibility is improved, but display area is reduced
Solution Approach 1:
The pixel regions are divided into multiple separate regions (first pixel region and second pixel region) that are spaced apart from each other. This segmentation allows independent optimization of each region and enables flexible device layouts while maintaining display functionality through the coupling lines that connect corresponding pixels across the non-pixel regions.
Solution Approach 2:
The patent introduces coupling lines that extend in the vertical direction (y-direction) to connect pixel regions that are separated in the horizontal direction. This dimensional approach allows the display to maintain continuity across non-pixel regions by utilizing the vertical dimension for signal transmission, thereby preserving display area while enabling layout flexibility.
2Area of stationary object
If coupling lines are used to connect gate control lines across pixel regions, then space utilization is improved, but device complexity increases
Solution Approach 1:
The coupling lines serve multiple functions: they connect gate control lines from different pixel regions, transmit control signals across non-pixel regions, and enable space-efficient layouts. This multi-functionality reduces the need for separate connection structures, thereby improving space utilization without proportionally increasing device complexity.
Solution Approach 2:
The coupling lines act as intermediary elements that bridge the gap between separated pixel regions. By introducing these intermediate connection structures, the patent enables efficient space utilization through compact layouts while managing complexity through standardized, repeatable coupling line designs that can be systematically integrated.

AI summary
A display device includes a first pixel region including a plurality of first pixels and a plurality of first gate control lines coupled to the first pixels, and a second pixel region spaced apart from the first pixel region. The second pixel region includes a plurality of second pixels and a plurality of second gate control lines coupled to the second pixels. The display device further includes a first non-pixel region disposed between the first pixel region and the second pixel region, and a first coupling line disposed in the first non-pixel region. The first coupling line commonly couples at least two first gate control lines and at least two second gate control lines.
