Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the gate driver and compensation patterns are disposed in the non-active area, then the signal output can be compensated, but the bezel area increases
Solution Approach 1:
The gate driver and compensation patterns are moved from the non-active area (2D plane outside active area) into the active area (2D plane within display region), utilizing the vertical dimension of the substrate structure. This dimensional repositioning allows compensation functionality to be integrated within the active display area, reducing bezel size while maintaining signal compensation capability
Solution Approach 2:
The active area is designed to serve multiple functions: it not only displays visual information but also accommodates the gate driver and compensation patterns. This multi-functional utilization of the active area eliminates the need for separate non-active area space, thereby reducing bezel area while maintaining compensation functionality
2Area of stationary object
If the bezel area is reduced to minimize the display apparatus size, then the display area increases, but the gate driver may not have sufficient space for proper operation
Solution Approach 1:
The active area is divided into multiple regions: a first area for displaying images and a second area for accommodating the gate driver and compensation patterns. This segmentation allows the gate driver to have sufficient operational space within the active area while maintaining a large overall display area, as the driver region is integrated rather than separated as a bezel
Solution Approach 2:
The gate driver is positioned within the active area by utilizing the vertical structure of the substrate, effectively using the z-dimension (depth/thickness) rather than consuming lateral space. This allows the gate driver to operate within the active area without reducing the lateral display area, thus maintaining both large display area and proper driver operation space
