Foot.The distance between every lead 17 and visible area 13 are d2.The distance d2 can be according to the area of required visible area 13
The laying area requirements of size and lead 17 adjust.In this present embodiment, the distance d2 be preferably between 0.2 millimeter with
Between 0.4 millimeter.
It is worth noting that, it is known because spacing of the adjacent legs 17 between one end of visible area is excessive, and make
Substrate 11 equipped with touch-control array and a plurality of leads 17 is in bonding processes because the bonding glue in lead areas and non-lead region is solid
It is different to change shrinking percentage, causes 11 surface irregularity of substrate.It, can be because of conductive film when the visible light of outside projection is by substrate 11
Surface irregularity and generate different interference phenomenon, and then can be formed between visible area and neighboring area a string it is uneven
Water ripples, cause visual difference.Therefore shortened by the amplification of visible area between lead 17 and visible area 13 away from
From d2, such as when distance d2 is less than 0.4 millimeter, the phenomenon that water ripples between visible area and neighboring area, i.e. can be more and more brighter
It is aobvious, it influences to show quality.
Accordingly, the present embodiment is equably supported by extension wire 177 is added equipped with touch-control array and a plurality of leads
Substrate 11 effectively avoids substrate 11 in bonding processes due to lead areas is different from the bonding adhesive curing in non-lead region contraction
Cause electrically conducting transparent film out-of-flatness.It, can be because of conductive film uneven surface when the visible light of outside projection is by substrate 11
It is whole and generate different interference phenomenon, and then form water ripples.To even if the area amplification of visible area 13, makes lead 17
It is adjacent to the distance between 13 one end of visible area and visible area and is less than 0.4 millimeter, there will not be the generation of water ripples phenomenon.According to
This, the present invention can solve transparent substrate 11 and cause surface irregularity because gluing and solidifying shrinks difference in pressing, cause because of light
Line interference is different to lead to the problem of water ripples, and under the amplification of the area of visible area 13, is still maintained visible area 13
Show quality.
