Engineering Contradiction Analysis
1Area of stationary object
If the display screen size is increased, then the screen area is improved, but the signal line length increases leading to higher resistance and signal delay
Solution Approach 1:
The signal lines are divided into multiple segments with different orientations. Specifically, reset signal lines include first reset patterns extending in a first direction and second reset patterns extending in a second direction, forming a grid-like structure that segments the signal transmission path and reduces the effective length in each direction.
Solution Approach 2:
The patent transitions from unidirectional signal lines to bidirectional grid-like signal line structures. By adding signal lines in both first and second directions that intersect to form multiple patterns, the patent creates a two-dimensional signal transmission network that reduces resistance and improves reliability.
2Length of stationary object
If the signal line length is increased, then the coverage area is improved, but the resistance increases causing signal delay
Solution Approach 1:
Signal lines are segmented into multiple directional components (first direction and second direction patterns) that work together to reduce the effective transmission distance in any given direction, thereby reducing signal delay while maintaining overall coverage.
Solution Approach 2:
The patent merges signal lines extending in different directions to form a comprehensive grid structure. This combination of first and second direction signal lines creates multiple transmission paths, reducing the effective length and resistance for signal transmission across the display screen.
3Length of stationary object
If the signal line length is increased, then the coverage area is improved, but the resistance increases affecting performance
Solution Approach 1:
The patent implements bidirectional signal line structures with patterns extending in both first and second directions, creating a two-dimensional transmission network that reduces resistance and improves reliability while maintaining comprehensive coverage across the display area.
4Productivity
If the refresh frequency is increased, then the display performance is improved, but the signal transmission requirements become more stringent
Solution Approach 1:
By segmenting signal lines into multiple directional patterns, the patent reduces the effective transmission distance and resistance, enabling faster signal transmission that supports higher refresh frequencies while maintaining transmission stability.
Solution Approach 2:
The merging of signal lines in multiple directions creates redundant transmission paths and reduces overall resistance, providing the signal transmission reliability needed to support increased refresh frequencies without compromising stability.
