Display Panel Ground-Line Layout for Touch ESD Protection

The patent applies preliminary action by pre-configuring the ground line with lower impedance and establishing the electrostatic protection circuit structure before electrostatic discharge occurs. This proactive design ensures that when electrostatic discharge happens, the protection mechanism is already in place and operational, preventing damage to touch signal lines and electrodes without requiring complex real-time response systems

The patent converts the harmful electrostatic discharge into a beneficial protective mechanism by designing the electrostatic protection circuit to preferentially discharge static electricity through the lower impedance ground line. This transforms the potentially damaging electrostatic energy into a controlled discharge path that protects critical touch signal lines and electrodes from damage

The patent applies local quality by creating a specific impedance characteristic in the ground line segment within the non-display area, making it have lower impedance compared to other ground lines. This localized impedance optimization is achieved by adjusting the conductor width or thickness in that specific region, allowing preferential discharge path creation without requiring high-precision impedance control across the entire device

The patent implements parameter changes by modifying the physical dimensions of the ground line conductor (such as increasing width or thickness) in the non-display area to reduce its impedance. This parameter adjustment creates a preferential discharge path for electrostatic electricity, directing it away from touch signal lines while maintaining manufacturability through standard fabrication process variations
