1Area of stationary object
If connection lines are extended in different directions to connect pad parts and pixel parts, then the display surface area can be increased, but the process complexity increases
Solution Approach 1:
The connection lines are divided into multiple segments extending in different directions. First connection lines extend in a first direction to connect first pad parts to first pixel parts, while second connection lines extend in a second direction to connect second pad parts to second pixel parts. This segmentation allows the display surface area to be increased without requiring a single complex connection path.
Solution Approach 2:
The connection lines utilize multiple spatial dimensions by extending in different directions (first direction and second direction). This multi-directional arrangement allows pad parts and pixel parts to be connected efficiently across the display area, maximizing the usable display surface while maintaining manageable connection paths.
2Device complexity
If scan driver and data driver are disposed on the same side of pixel part, then the device structure is simplified, but the connection line length increases
Solution Approach 1:
The scan driver and data driver are merged into a single location on the same side of the pixel part. This consolidation simplifies the device structure and reduces the number of separate driver components, while the connection lines are configured to efficiently reach both drivers from their respective pad parts.
Solution Approach 2:
Connection lines utilize multi-directional extension to reach the consolidated drivers. First connection lines extend in a first direction to reach the scan driver, while second connection lines extend in a second direction to reach the data driver, optimizing the path length despite the unified driver location.
3Productivity
If first connection line and second connection line extend in different directions, then signal transmission efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
Different connection lines are assigned different extension directions based on their specific connection requirements. First connection lines extend in a first direction optimized for connecting first pad parts to first pixel parts, while second connection lines extend in a second direction optimized for connecting second pad parts to second pixel parts. This localized optimization improves signal transmission efficiency for each connection path.

AI summary
A display device may include a pixel part including a pixel, a pad part including a first pad part and a second pad part, and a connection line including a first connection line extending in a first direction and a second connection line extending in a second direction. The display area may include a first display area overlapping the first pad part in the first direction and a second display area overlapping the second pad part in the first direction.
