Abstract
The invention discloses an array substrate and a display device with the array substrate. The array substrate comprises at least two terminals, wherein the terminals are arranged at intervals in the width direction of the at least two terminals; each terminal comprises a bonding pad part; each bonding pad comprises a groove used for containing a conductive adhesive; an opening of each groove is formed in the side wall in the length direction of the each terminal; the positions of the openings of adjacent terminals are staggered, so that the conductive adhesive overflowing from the adjacent terminals are not connected. Due to the fact that the opening is formed at the groove for containing the conductive adhesive in each terminal, when the terminal and an external circuit are bonded, the overflow conductive adhesive is guided, and the overflow position and the overflow direction of the conductive adhesive are controlled; due to the fact that the positions of the openings of the adjacent terminals are staggered, the conductive adhesive does not simultaneously overflow at the opposite positions of the adjacent side walls of the adjacent terminals, the probability that the adjacent terminals have short-circuit fault is reduced, and the yield rate of a product is improved.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.Following examples for illustration of the utility model, but can not be used for limiting scope of the present utility model.
Fig. 1 is the structural representation of terminal in prior art, as can be seen from the figure, the pad 100 of two terminals and groove 500 surrounding of pad 200 are closed, the probability that nation's timing conducting resinl 400 overflows on groove 500 4 sidewalls is equal, and direction and position have unpredictable property, therefore the conducting resinl 400 that the groove 500 of the pad of terminals of adjacent overflows in relevant position connects and causes the probability of short circuit very large, as shown in Figure 2.
Embodiment one:
Fig. 3 is the structural representation of the terminal of the array base palte of enforcement one of the present invention, the array base palte of the present embodiment, comprise two terminals, described two terminals are arranged at the Width interval of described two terminals, each described terminal comprises pad, each described pad comprises the groove 500 for arranging conducting resinl 400, described groove 500 is respectively arranged with an opening on the sidewall of two length directions of each described terminal, and stagger in the position of these two openings on the length direction of described terminal, the conducting resinl 400 that adjacent described terminal overflows is not connected.In Fig. 3, pad 200 arranges opening 201, pad 100 arranges opening 101, and stagger in the position of two openings on the length direction of described terminal.
Fig. 4 utilizes the terminal of the array base palte of enforcement one of the present invention to carry out the surely rear conducting resinl spill-over effects schematic diagram of nation, and as we can see from the figure, because opening staggers mutually, conducting resinl 400 overflows in diverse location at opening part, not easily connects and causes short circuit; And due to the guidance quality of opening, first conducting resinl 400 overflows from opening, and can not overflow from other positions of groove, decrease the probability that conducting resinl 400 is short-circuited in other positions of groove, in addition, the welding disk of each terminal is offered two openings, the conducting resinl that each opening is overflowed is few and more difficult to be short-circuited.
Further, stagger in the position of the welding disk of adjacent described terminal on the length direction of described terminal, the opening of each described terminal is staggered with the welding disk of terminals of adjacent on the length direction of described terminal, and this design avoids the conducting resinl 400 overflowed to be connected to terminals of adjacent further.
Further, the width of described welding disk be greater than with in the length direction of described terminal other parts connected, be beneficial to nation and determine device.
Further, the sidewall of described groove comprises metal level 302, passivation layer 303 and transparency conducting layer 304 from top to bottom, described passivation layer 303 excalation, thus forms described opening, this kind of structure owing to just making passivation layer 303 excalation, so be easy to formed.Preferably, below the metal level of described sidewall, one deck glass 301 can be added, for protecting metal level, as shown in Figure 6.
Conducting resinl 400 is generally anisotropy conductiving glue, wherein arranges metallics, thus avoids the short circuit that terminals of adjacent occurs on substrate further.
Embodiment two:
Fig. 5 is the terminal pad structural representation of the array base palte of enforcement two of the present invention, the difference of this embodiment and embodiment one is, opening is positioned at the same side of groove, namely the opening of terminals of adjacent is non-conterminous, the conducting particles of the conducting resinl 400 therefore overflowed by opening can not connect and causes short circuit, the probability of further reduction terminals of adjacent short circuit, improves product yield.All the other structures of the array base palte of this embodiment are identical with embodiment one, repeat no more here.
The invention also discloses a kind of display device, described display device comprises above-mentioned terminal.
The present invention passes through in terminal conducting resinl groove designed openings, nation's timing is carried out at terminal and external circuits, for the conducting resinl guiding of overflowing, control spillover position and the direction of conducting resinl, and staggered by the aperture position designing adjacent described terminal, make the corresponding position of the adjacent wall of terminals of adjacent can not overflow conducting resinl simultaneously, reduce the probability of terminals of adjacent short circuit, improve product yield.
Above embodiment is only for illustration of the present invention, but not limitation of the present invention.Although with reference to embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, various combination, amendment or equivalent replacement are carried out to technical scheme of the present invention, do not depart from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of right of the present invention.
