Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
In the utility model embodiment " on ", the sequencing of D score when being formed with film be as the criterion, and such as, above refers to relatively in the film portion of rear formation, under refer to the film portion relatively formerly formed.Be to be understood that, these directional terminology are relative concepts, they for relative to description and clarification, it correspondingly can change according to the change in placed orientation.
As shown in Figure 2, be the electrode layer schematic diagram in a kind of contact panel, wherein, touch-control drive electrode 11 and touch-control sensing electrode 12 are positioned at same layer.Contact panel as shown in Figure 2, because the joint-cutting at F place, region is more, the joint-cutting at E place, region is less, thus region E and F place, region exist touch-control difference.
In order to avoid above-mentioned touch-control difference, as shown in Figure 3, the touch-control drive electrode 11 on contact panel and touch-control sensing electrode 12 are all formed with many joint-cuttings, comprise multiple electrode strip 111 to make touch-control drive electrode 11 and touch-control sensing electrode 12.Because the electrode strip of vertical bar shape easily diffraction occurs, as shown in Figure 3, existing electrode strip 111 is bending, and many strip electrodes bar 111 is connected to form touch-control drive electrode 11, second connecting portion 121 and many strip electrodes bar 111 is connected to form touch-control sensing electrode 12 by the first connecting portion 112.
But due to the impact of etching technics, the side of electrode strip is generally the dip plane with certain angle.The electrode strip of bending can form light and dark striped down reflective, and its Crack cause is as follows:
As shown in Figure 3, a that electrode strip 111 comprises to different directions bending is capable and b is capable, and no matter is that a is capable or b is capable, and the side of electrode strip 111 is dip plane.As shown in Fig. 4 (a), the electrode strip 111 that a is capable comprises dip plane a1 and dip plane a2, and the electrode strip 111 that b is capable as Suo Shi Fig. 4 (b) comprises dip plane b1 and dip plane b2.As shown in Figure 1, under certain angle, user can receive the some light of the dip plane a1 of a column electrode bar 111 and the dip plane b1 reflection of b column electrode bar 111.But the light that the light that the dip plane b1 that user receives reflects reflects than dip plane a1 is few, and therefore, user sees that a of electrode strip 111 is capable brighter than b row, thus occurs light and shade striped, causes Consumer's Experience poor.
In order to overcome the problems referred to above, as shown in Figure 5, the utility model embodiment provides a kind of electrode layer 20, comprise: many in the same direction (101 directions shown in Fig. 5) extend and have certain thickness first electrode strip 21 and many in the same direction (101 directions shown in Fig. 5) extend and there is certain thickness second electrode strip 22, first electrode strip 21 and the second electrode strip 22 is spaced.
