Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrostatic protection circuits are added to the display panel, then anti-static ability is improved, but device complexity increases
Solution Approach 1:
The electrostatic protection circuit is merged with the existing shift register circuit structure. The protection circuit shares the same signal line transmission path and is integrated into the same circuit board layout, allowing static electricity discharge functionality to be combined with the existing driving circuit without adding separate independent protection modules.
Solution Approach 2:
The electrostatic protection circuit is designed to work alongside the shift register circuit, enabling the same circuit board to perform both driving functions and electrostatic protection functions. The protection circuit can discharge static electricity while the shift register drives the display, achieving multi-functionality in a unified circuit design.
2Reliability
If electrostatic protection circuits are disposed in the display region, then anti-static ability is improved, but the display area is reduced
Solution Approach 1:
The electrostatic protection circuits are selectively disposed only in specific regions where static electricity accumulation is most likely to occur, such as near the edges of the display panel and adjacent to signal line endpoints. This localized placement provides targeted protection while minimizing the impact on the overall display area.
Solution Approach 2:
The protection circuits are positioned in advance at strategic locations along the signal lines, particularly at endpoints facing panel edges, to prevent static electricity from affecting the display before it can cause damage. This preliminary positioning ensures protection is in place before static discharge events occur.
