Second embodiment
Fig. 5 is the synoptic diagram of second embodiment provided by the invention; The same with first embodiment, also comprise a plurality of arraying bread boards on the array base palte that second embodiment of the invention provides, be divided into the frame region of viewing area shown in viewing area, the encirclement on the said arraying bread board; What also be provided with on the said arraying bread board has a short bar device; The same with first embodiment, comprise first short bar 11, second short bar 12, the 3rd short bar 13, the 4th short bar 14 and the 5th short circuit 15 such as the short bar device of arraying bread board 1012, above structure is identical with first embodiment; Be not described in detail here; Be that with the first embodiment difference in the array base palte that second embodiment provides, the public electrode of short bar device on the arraying bread board 1011 and adjacent arraying bread board 1012 wiring 1014 is electrically connected.
Frame region at each arraying bread board all has a large amount of public electrode wirings to be used for the public electrode of all pixel cells is linked together; And for the public electrode voltages that makes entire pixel array is consistent as far as possible, can be with the public electrode wiring with the pel array of very wide wiring grommet around the viewing area.Frame region 1013 like array base palte 1012 connects up 1014 with regard to the public electrode that has that is provided with.First short bar 11 of the short bar device on the arraying bread board 1011, second short bar 12, the 3rd short bar 13, the 4th short bar 14 and the 5th short bar 15 respectively through connecting line 171,172,173,174 and 175 and adjacent arraying bread board 1012 public electrodes wiring 1014 be electrically connected.Said connecting line 171,172,173,174 and 175 material can be identical with the material of the pixel electrode of array base palte, and in the array base palte processing procedure, accomplish synchronously with pixel electrode, also can use other conductive material in other embodiments.Said connecting line 171,172,173,174 and an end of 175 first short bar 11 through the short bar device on via hole and the arraying bread board 1011, second short bar 12, the 3rd short bar 13, the 4th short bar 14 and the 5th short bar 15 respectively are electrically connected, and the other end can be electrically connected through via hole and adjacent arraying bread board 1012 public electrodes wiring 1014.
The array base palte of second embodiment provided by the invention; Through the short bar device on the arraying bread board is electrically connected through the public electrode wiring of connecting line and adjacent arraying bread board respectively; The public electrode wiring of short bar device through adjacent arraying bread board is electrically connected forms equipotential; And can make the short bar device equipotential all on the arraying bread board on array base palte previous column or delegation's arraying bread board even whole the array base palte; Because the 5th short bar is to link to each other with the public electrode of this arraying bread board; The public electrode of this arraying bread board links to each other through the short bar device of public electrode wiring and adjacent arraying bread board again, if a short bar device suffers that static impacts, static can be mobile to the public electrode on whole the array base palte; Common electrode resistance on whole array base palte can effectively reduce the voltage of static, prevents the damage of static to the short bar device.
And said short bar device is connected with adjacent arraying bread board through connecting line, in follow-up operation; Array base palte and color membrane substrates fit and form a plurality of liquid crystal cells; In the cutting action of liquid crystal cell, connecting line is cut off from line of cut 18, and the short bar device just can operate as normal; Saved the operation that to cut connecting portion 16 among first embodiment, provided cost savings greatly.
The 3rd embodiment
Fig. 6 is the synoptic diagram of the 3rd embodiment of array base palte provided by the invention; In the present embodiment; Connecting portion 20 electrically connects with first short bar 11, second short bar 12, the 3rd short bar 13, the 4th short bar 14 and the 5th short bar 15 respectively; Identical with first embodiment here, no longer do detailed description, only the structure that is different from the foregoing description is described in detail.------FOG PAD 21, said FOGPAD 21 also are electrically connected with connecting portion 20 on arraying bread board, also to comprise the pin that connects FPC (Flexible Printed Circuit, flexible PCB).Because the distance of FOG PAD 21 and short bar device is very approaching; Generally have only between 0.6～0.7mm; So the possibility of mutual discharge is also arranged between FOG PAD 21 and the short bar device, FOG PAD 21 also is electrically connected with connecting portion 20 also can further protects short bar device and FOG PAD21.In cutting connecting portion 20, also FOG PAD21 and connecting portion 20 are separated.
Further said FOG PAD21 also can be connected in the public electrode wiring of adjacent arraying bread board; Can also play a part to play equally to prevent electrostatic damage; And can be synchronously in the cutting action of liquid crystal cell and the public electrode wiring separate, saved independent cutting action.
Each embodiment adopts the mode of going forward one by one to describe in this instructions, and what each embodiment stressed all is and the difference of other embodiment that so description is fairly simple, relevant part gets final product referring to the explanation of device part.
