Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a straight connection line is used to connect the pad area to the data line, then the manufacturing process is simple, but the dead area cannot be sufficiently reduced
Solution Approach 1:
The connection line is designed with a bent structure including first and second portions arranged in different directions, creating a curved path that efficiently utilizes the available space between the pad area and data line, thereby reducing the dead area while maintaining manufacturing simplicity
Solution Approach 2:
The connection line transitions from a single-direction straight path to a multi-directional bent path by incorporating portions arranged in different directions, effectively utilizing two-dimensional space to minimize the dead area without significantly increasing manufacturing complexity
2Area of stationary object
If the connection line is extended further into the display area to reduce dead area, then the dead area is reduced, but signal transmission stability may be compromised
Solution Approach 1:
The bent connection line with optimized curvature reduces the dead area while the specific configuration of first and second portions ensures that the signal transmission path remains stable and does not excessively extend into the display area, maintaining signal integrity
Solution Approach 2:
The connection line geometry is optimized by adjusting the bend radius and the lengths of the first and second portions, achieving a balance between reducing dead area and maintaining signal transmission stability within the available space
3Area of stationary object
If a bent connection line structure is implemented to reduce dead area, then the dead area is reduced, but the manufacturing process becomes more complex
Solution Approach 1:
The bent connection line structure with first and second portions can be manufactured using standard thin-film deposition and patterning processes, achieving the curved geometry through conventional photolithography masks without requiring complex additional manufacturing steps

AI summary
A display device includes: a substrate including a display area, a peripheral area outside the display area, and a pad area in the peripheral area; a data line in the display area; and a first connection line in the display area and connected to the data line to transmit, to the data line, a signal from the pad area, wherein the first connection line includes a first portion in a first direction and a second portion bent from the first portion and in a second direction.
