Abstract

The invention provides an electrostatic protection circuit structure arranged in a display panel. The circuit structure comprises a first through-hole conductive layer and a thin film transistor (TFT). The first through-hole conductive layer is in bridge connection between a second signal line which inputs input signals and a first signal line which outputs output signals, and the second signal line is connected with the first signal line via the first through-hole conductive layer. The gate electrode of the TFT is connected with the drain electrode of the TFT, the gate electrode and / or drainelectrode of the TFT is connected with the second signal line, and the source electrode of the TFT is connected with the first signal line. The invention also provides the display panel and a displaydevice. According to the electrostatic protection circuit structure, display panel and display device, the problems that line break due to too high electrostatic level in the signal input end occurs in the display panel and signals cannot be output normally in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of display panels, in particular to an electrostatic protection circuit structure, a display panel and a display device. Background technique [0002] In order to prevent the static electricity of the display panel during the process of manufacturing and transportation from causing damage to the conductive lines or conductive layers, ESD is often introduced into the design of the display panel. [0003] like figure 1 and figure 2 As shown, the display panel introduces the signal line 2 of the input signal G_in in the second metal layer L2 / , the signal line 1 of the output signal G_out is drawn out on the first metal layer L1 / , and pass through the via conductive layer 3 across the second metal layer L2 and the first metal layer L1 / Realize the electrostatic protection between the above two signal lines, which is equivalent to the signal line 2 of the input signal G_in / and the signal line 1 of th...
