Embodiment two
Fig. 4 is the structural schematic diagram near array substrate provided by Embodiment 2 of the present invention binding pad and dummy pad.
Referring to shown in Fig. 4, on the basis of the above embodiment 1, second embodiment of the present invention provides a kind of array substrate, embodiment two with
Embodiment one is compared, and is in place of the difference of the two: binding pad 70 and dummy pad 80 are provided in non-display area 20.
Specifically, being provided at least one dummy pad 80 in non-display area 20, dummy pad 80 is located at two neighboring tie up
Determine between pad 70.
It should be noted that it is provided with dummy pad 80 between the adjacent binding pad 70 of the present embodiment, the dummy pad
On 80 and it is not connected with fan-out line 30 and data signal line 40, that is, the missing solder disk between adjacent binding pad 70 is set.Due to tying up
Determine pad 70 and be connected with fan-out line 30 and data signal line 40, therefore binds pad 70 and have a large amount of data during the work time
Signal passes through, and the spacing between two neighboring binding pad 70 is smaller, and it is dry that signal can occur between two neighboring binding pad 70
The problem of disturbing influences the stable signal transmission and accuracy of fan-out line 30 and data signal line 40.
In view of this, the present embodiment setting dummy pad 80 can not influence to bind the premise that is normally arranged of pad 70
Under, increase the spacing of adjacent binding pad 70, to avoid the problem that signal interference occurs.
Wherein, shorting stub 50 is connected to the first connecting pin 81 of dummy pad 80, the second connection end 82 of dummy pad 80
It is connected to preset data signal wire 60.
