Protection scope of the present invention.
In addition, in the present embodiment, also to enter on the path between ground wire and above-mentioned public electrode wire, data wire, scan line
One step is provided with the bilateral diode of low resistance.Because the public electrode wire of existing partial display (data wire and is swept
Retouch line similarly) current potential in 7V to 8V or so be reasonable value, rather than 0V.Therefore only need to the current potential reduction of its public electrode
To 7V-8V or so.(7V-8V described above, can be according to specific feelings after the current potential that public electrode is reached the standard grade is more than certain thresholding
Condition rationally set), the bilateral diode of the present embodiment can just be turned on, so as to carry out Electro-static Driven Comb by ground wire.Discharging
Cheng Zhong, when the current potential of public electrode wire is reduced to above-mentioned thresholding or so, bilateral diode disconnects, so as to terminate Electro-static Driven Comb.
Certainly, preferably, the bilateral diode of the present embodiment can be specifically located at metallic framework and ground wire it
Between, because metallic framework is outer rim region, therefore bilateral diode will not take the viewing area of centre, for arrangement requirement more
Plus flexibly.
On the other hand, another embodiment of the present invention also provides a kind of preparation method of display device, including makes display
Described in the step of panel and use shell envelope frame the step of display panel；
