Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no anti-static unit is provided in the conventional array substrate, then the device complexity is reduced, but the reliability deteriorates due to electrostatic discharge damage
Solution Approach 1:
The gate lines themselves serve the dual function of signal transmission and electrostatic discharge conduction. By electrically connecting multiple gate lines through the static-conducting device, the system uses its existing components (gate lines) to protect itself from ESD damage, eliminating the need for separate anti-static units and maintaining device simplicity while improving reliability.
2Reliability
If a static-conducting device is added to connect gate lines, then the anti-electrostatic discharge ability is improved, but the device complexity increases
Solution Approach 1:
The static-conducting device provides multi-functionality by enabling gate lines to serve both as signal transmission pathways and as electrostatic discharge conduction paths. This universal approach allows the same structural elements to perform multiple functions, improving ESD protection without requiring entirely separate protective components for each function.
3Ease of manufacture
If electrostatic charges are accumulated on gate lines, then the manufacturing process is simplified, but the harmful factors increase due to ESD occurrence
Solution Approach 1:
The static-conducting device acts as an intermediary that provides a controlled discharge path for electrostatic charges. Instead of allowing charges to accumulate harmfully on individual gate lines, the mediator (static-conducting device) redirects the electrical energy through a designated pathway that connects multiple gate lines, thereby dissipating the harmful electrostatic energy in a controlled manner and preventing ESD damage to pixels and circuits.
