Part is exemplified as the first diode d1, and the second electronic component is exemplified as the second diode d2, the first diode d1 and the two or two pole
Pipe d2, is electrically connected to each other with serial arrangement, and wherein electrostatic discharge protection circuit 140 is electrically connected to first voltage end vt1 and
Two voltage end vt2, first voltage end vt1 and second voltage end vt2 provide first voltage and second voltage respectively, and first
Voltage is different from second voltage, and in the preferred embodiment, first voltage is more than second voltage.In the present embodiment, the one or two pole
The negative electrode of pipe d1 is electrically connected to first voltage end vt1, and its anode is electrically connected to the first electric-conductor 130.Second diode
The negative electrode of d2 is electrically connected to the anode of the first diode, and its anode is electrically connected to second voltage end vt2.Specifically,
First diode d1 is electrically connected to the first electric-conductor 130 through contact vt, and, the negative electrode of the second diode d2 can pass through and connects
Point vt is electrically connected to the first electric-conductor 130.Because the anode of the first diode d1 is electrically connected at the first electric-conductor 130, cloudy
Pole is electrically connected at first voltage end vt1, therefore, when the voltage of the first electric-conductor 130 is less than first voltage and the first diode
During forward conducting voltage (turn-on voltage) sum of d1 that is to say, that when the first electric-conductor 130 do not have quiet in a large number
During electric charge, the first diode d1 does not turn on.And, when the voltage of the first electric-conductor 130 is more than second voltage and the two or two pole

In dynamic circuit layer 114.For example, the first diode d1 and the second diode d2 can for diode (diode), check and receive two poles
Manage (zener diode) or other are suitable for manufacturing in the diode of active circuits layer 114, but be not limited.Additionally, first
The quantity of diode d1 can be multiple, and can be one another in series or in parallel, and in the same manner, the quantity of the second diode d2 is alternatively many
Individual, and can be one another in series or in parallel.
In the present embodiment, because the electrostatic charge entering panel 100 via protection board 160 can pass through the first electric-conductor 130
Conductive path conduct to electrostatic discharge protection circuit 140 so that can be by the conducting of the first diode d1 or the second diode d2
Conducting by substantial amounts of positive electrostatic charge and negative electrostatic charge diversion the first plate body 110, therefore, by the electrostatic defending of the present embodiment
