Embodiment Construction
[0034] The electrostatic protection element of the electrostatic discharge protection circuit in the embodiment of the present invention increases the discharge path of static electricity and improves the performance of static electricity discharge through the bottom-gate TFT and top-gate TFT that are connected in parallel and share the active layer, source, and drain. Speed, improve the anti-static ability of the ESD protection circuit.
[0035] Generally, the structure composed of the bottom-gate TFT and the top-gate TFT connected in parallel and sharing the active layer and the source and drain can be called a double-gate TFT.
[0036] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0037] see figure 1 As shown, the first electrostatic discharge protection circuit provided by the embodiment of the present invention is located in the non-display area of the display panel and includes at le...
