Engineering Contradiction Analysis
1Area of stationary object
If the routing path length of the repair line is increased to cover large-scale liquid crystal display panels, then the coverage area is improved, but signal attenuation increases
Solution Approach 1:
An amplifier is introduced as an intermediary component within the integrated circuit chip to boost the signal transmitted through the repair line. The amplifier receives the control signal from the repair line and amplifies it before transmitting to the pixel, thereby compensating for signal attenuation caused by the increased routing path length in large-scale display panels.
2Area of stationary object
If the routing path length of the repair line is increased to cover large-scale liquid crystal display panels, then the coverage area is improved, but manufacturing cost increases
Solution Approach 1:
The amplifier is merged with the integrated circuit chip, combining multiple functions (signal amplification and existing driver functions) into a single component. This integration avoids the need for separate amplifier components and their associated mounting processes, thereby controlling manufacturing cost while enabling coverage of large-scale display panels.
3Reliability
If an amplifier is added to the system to reduce signal attenuation, then signal quality is improved, but device complexity increases
Solution Approach 1:
The amplifier function is merged into the existing integrated circuit chip, so that the chip performs both signal amplification and driver functions. This integration approach improves signal quality through amplification while minimizing the increase in device complexity by utilizing the existing chip structure rather than adding separate discrete components.
