Engineering Contradiction Analysis
1Area of stationary object
If gate driving units are integrated within the display area, then bezel width is reduced and display area utilization is enhanced, but device complexity increases due to concurrent fabrication requirements
Solution Approach 1:
The gate driving units are merged with the display panel fabrication process, allowing both components to be manufactured simultaneously on the same substrate. This integration eliminates the need for separate chip mounting and reduces the bezel width while maintaining manufacturing feasibility through process consolidation.
Solution Approach 2:
The fabrication process is designed to perform multiple functions concurrently: forming both the display pixels and the gate driving units in the same manufacturing sequence. This multi-functional approach allows a single fabrication process to produce both the display area and the integrated driving circuits, reducing overall device complexity despite the advanced integration.
2Ease of manufacture
If signal transmission lines are arranged between pixel groups, then manufacturing costs are reduced through integrated fabrication, but display area is reduced due to line occupation
Solution Approach 1:
The signal transmission lines are strategically positioned only in specific regions between pixel groups where they are most needed for signal routing. This localized arrangement minimizes the area occupied by non-display elements while maintaining effective signal transmission, thereby preserving maximum display area while enabling integrated fabrication.
3Length of stationary object
If gate driving units are disposed on the display area, then bezel width is minimized, but reliability may be affected by increased interference between signal lines and pixels
Solution Approach 1:
Insulating structures are introduced as intermediary elements between the gate driving units and the pixel groups. These insulating layers act as mediators that electrically isolate the signal transmission lines from the pixels, preventing signal interference and maintaining reliability while allowing the gate driving units to be positioned within the display area for minimal bezel width.
