When first terminal 231 and Second terminal 232 bind area 230 in integrated circuit along the extending direction setting on the second side
On, first terminal 231 and Second terminal 232 can be and be arranged in parallel in integrated circuit binding area along the extending direction on the second side
On 230, that is to say, that first terminal 231 and Second terminal 232 are arranged in parallel.In this way, facilitate setting for terminal
Meter, and the later period is facilitated to be routed.
Certainly, first terminal 231 can be with Second terminal 232 may not be along the extending direction on the second side it is parallel
Setting is in integrated circuit binding area 230, that is to say, that first terminal 231 and Second terminal 232 are to exist greater than 0 and be less than
The angle of 180 degree.Such set-up mode is flexible.
Wherein, extending direction can be understood as being arranged around the boundary line along the side, may be with the boundary where the side
Line contact, it is also possible to not contacted with the boundary line where the side.
First terminal 231 and Second terminal 232 are arranged along same one side extending direction in integrated circuit binding area 230,
In the embodiment of the present application, first terminal 231 and Second terminal 232 are identical as the design method of terminal in the prior art, can be with
The cost of relative reduction display panel.
In the embodiment of the present application, the design method of third terminal 233 is different or third is fanned out to 263 winding mode of cabling not
Together, the structure of the display panel is also different, below to the structure for the display panel that may relate in the embodiment of the present application into
Row illustrates.
The structure of the first possible display panel are as follows:
Please continue to refer to Fig. 2 B, third terminal 233 binds area 230 in integrated circuit along the extending direction setting on the second side
On, and third is fanned out to cabling 263 and is electrically connected by the second side with third terminal 233.
Specifically, continuing with by taking Fig. 2 B as an example, first terminal 231 and Second terminal 232 along the second side extending direction
It is arranged in parallel in integrated circuit binding area 230, third terminal 233 is arranged along the extending direction on the second side ties up in integrated circuit
Determine in area 230.And third is fanned out to cabling 263 and connect by the second side with third terminal 233.
Application embodiment in, second be fanned out to cabling 261 and third be fanned out to cabling 263 wire laying mode it is identical, be conducive to letter
Change wiring process, improves the production efficiency of display panel.
The structure of second of possible display panel are as follows:
First terminal 231 and Second terminal 232 are arranged along the extending direction on the second side binds area 230 in integrated circuit
On, third terminal 233 is along the extending direction setting on the second side in integrated circuit binding area 230.And third is fanned out to cabling
263 are electrically connected by third side with third terminal 233.Cabling 261 is fanned out to about first, the first signal wire 251, second is fanned out to away
The connection of line 262, second signal line 252, Second terminal 232 and first terminal 231 is referred to the content discussed above, herein
It repeats no more.
First terminal 231 can be set relative to third terminal 233 further from the first side, first terminal 231 can be set
Set relative to third terminal 233 closer to the first side, both of these case is introduced respectively below.
The structure one of second of possible display panel specifically:
Referring to figure 3., first terminal 231 is arranged to be relatively farther from the first side relative to third terminal 233.
Specifically, first be fanned out to cabling 261 had with the wiring that third is fanned out to cabling 263 it is overlapping, at this time can be by first
It is fanned out to cabling 261 and third is fanned out to the setting of the different layer of cabling 263.Different layer setting is for example, be arranged insulating layer in overlapping region.By different
Layer setting, to avoid first from being fanned out to the normal use that cabling 261 is fanned out to the overlapping influence display panel of cabling 263 with third.
It should be noted that Fig. 3 fans for the ease of clearly illustrating each position for being fanned out to cabling 260 in Fig. 3 with first
Cabling 261 and third are fanned out to for the quantity of cabling 263 is one out, but do not limit actually first be fanned out to cabling 261 with
Third is fanned out to the quantity of cabling 263.
The structure two of second of possible display panel specifically:
Referring to figure 4., first terminal 231 can be set relative to third terminal 233 closer to the first side, and first end
Son 231 is closer to the first side relative to Second terminal 232, and third terminal 233 is closer to third relative to Second terminal 232
Side.
In set-up mode in the embodiment of the present application, avoids first from being fanned out to cabling 261 and third is fanned out to the friendship of cabling 263
Folded situation, it is opposite to can simplify wiring process.Third is one perpendicular when binding in area 230 for integrated circuit with second
Side, and from first when being different.
In Fig. 3 or embodiment shown in Fig. 4, since first terminal 231, Second terminal 232 and third terminal 233 are all provided with
It sets on the extending direction on the second side, therefore, first, which is fanned out to cabling 261, can connect by the first side with first terminal 231, the
Two, which are fanned out to cabling 262, can connect with Second terminal 232 by the second side, third be fanned out to cabling 263 can pass through third side and
