[embodiment]
Fig. 3 illustrates the schematic top plan view of element on the substrate of display panel of one embodiment of the present invention.As shown in Figure 3, the display panel of present embodiment comprises: substrate (not illustrating, for example is glass substrate); Be arranged on many first signal wires 211 on the described substrate; Be arranged at least two first p-wires 251 on the described substrate; Be arranged on a plurality of first on-off elements 261 on the described substrate, the input end 2612 of described a plurality of first on-off elements 261 connects described first p-wire 251, output terminal 2613 corresponding first ends 2112 that connect described first signal wire 211 of each described first on-off element 261; Be arranged on first control line 241 of the control end 2611 of described a plurality of first on-off elements 261 of connection on the described substrate; Between described first control line 241 and described at least two first p-wires 251, be respectively arranged with electrostatic protection device 28.In the ordinary course of things, electrostatic protection device 28 presents high-impedance state, is similar between first p-wire 251 and first control line 241 and opens circuit.But when occurring static release on one first p-wire 251, can produce very high voltage, this voltage can act on first control line 241 by electrostatic protection device 28, thereby each first on-off element 261 is opened, the voltage that static discharges can disperse to be discharged on many first signal wires 211, has avoided a certain first on-off element 261 is caused damage.
The display panel of present embodiment also comprises: be arranged on many secondary signal lines 231 on the described substrate, described many secondary signal lines 231 crisscross described many first signal wires 211; Be arranged at least two second p-wires 252 on the described substrate; Be arranged on a plurality of second switch elements 262 on the described substrate, the input end 2622 of described a plurality of second switch elements 262 connects described second p-wire 252, output terminal 2623 corresponding first ends 2311 that connect a described secondary signal line 231 of each described second switch element 262; Be arranged on second control line 242 of the control end 2621 of the described a plurality of second switch elements 262 of connection on the described substrate; Between described second control line 242 and described at least two second p-wires 252, be respectively arranged with electrostatic protection device 28.The display panel of present embodiment also comprises: first line 291 of floating, and floating described first is respectively arranged with electrostatic protection device 28 between line 291 and described many first signal wires 211; Second line 292 of floating, floating described second is respectively arranged with electrostatic protection device 28 between line 292 and the described many secondary signal lines 231; Described first control line 241 is connected with 242 conductings of described second control line; Described first the line 291 and described second line conducting of floating of floating is connected 292; Described first line 291 and second of floating is floated and is provided with electrostatic protection device 28 between line 292 and described first control line and described second control line.When occurring static release on certain bar first signal wire 211, can produce very high voltage, this voltage can act on first control line 241 by electrostatic protection device 28, thereby each first on-off element 261 is opened, the voltage that static discharges can disperse to be discharged on many first signal wires 211, has avoided a certain first signal wire 211 is damaged.Same principle, the display panel of present embodiment can avoid the static release on a certain secondary signal line 231 to damage.
Because display panel is less at the device that second end of first signal wire or secondary signal line is provided with, circuit is sparse relatively, and in the present embodiment, described first floats, and second end 2112 that line 291 closes on described many first signal wires 211 is provided with; Described second floats, and second end 2312 that line 292 closes on described many secondary signal lines 231 is provided with.
In order to make diagram clear, only illustrated 6 first signal wires 211 and 3 secondary signal lines 231 among Fig. 3, the quantity of first signal wire and secondary signal line can be adjusted as required in actual use.
Fig. 4 illustrates the structural representation of the on-off element of one embodiment of the present invention, and Fig. 5 illustrates the structural representation of the on-off element of another embodiment of the present invention.Electrostatic protection device 28 in the above-mentioned embodiment can comprise it being two diodes of differential concatenation as shown in Figure 4, can be point discharge structure as shown in Figure 5, can be electric capacity, also can be the combination of these structures.
