Abstract

This invention relates to an electrostatic discharge protection circuit, particularly a protection circuit used in LCD panel. It can prevent the damage of driving circuit due to electrostatic discharge (ESD) effect. Mainly, the ending terminal of each driving circuit on the display panel has a tip part formed, and the panel edge side corresponding to the tip part has at least a discharge electrode. The ending terminal of the discharging electrode also has a tip part of discharging electrode corresponding to the tip part of each driving circuit. Thus, when the driving circuit has static charges, the tip part releases the static charges to the corresponding discharging electrode. It prevents the driving circuit and the connected electronic components from being damaged by the sudden large current. It not only simplifies the manufacturing process, but also saves the cost.

Similarly, a second electrode tip portion 291 is also formed at the terminal position of the second discharge electrode 29, and the second electrode The tip portion 291 is adjacent to the second tip portion 231 of the gate busbar 23 and faces each other. When the gate busbar 23 is locally charged with static electricity due to friction or other reasons, the electrostatic charge can pass through The second tip portion 2 3 1 of the gate bus bar 2 3 is slowly discharged to the corresponding second electrode tip portion 2 9 ^ and the first-discharge electrode 29 to prevent the gate bus line 2 3 When the electrostatic charge is charged to a certain level, it is immediately discharged to the adjacent gate bus line 2 3, the data bus line 2 1 or an electronic component electrically connected thereto, so as to achieve the purpose of protecting the driving circuit. Through the second tip portion 2 at the gate busbar 23 31 and discharging to the corresponding second electrode tip portion 2 91 and the second discharge electrode 29 may also cause damage to the second tip portion 231, the second electrode tip portion 291, or the second discharge electrode 29.
