Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Please refer to Fig. 1 to shown in Figure 3; The present invention relates to the wire structures of a kind of double-deck ITO; Said double-deck ITO layer comprises the first touch-control electrode 1 and several second touch-control electrodes 2 that are arranged in parallel that several are arranged in parallel; The said first touch-control electrode 1 and the said second touch-control electrode, 2 mutual homeotropic alignments, the said first touch-control electrode 1 is layed in wherein one deck ITO, and the said second touch-control electrode 2 is layed in another layer ITO.
The said first touch-control electrode 1 comprises the support body 101 that main body 100 and autonomous agent 100 extend and be arranged in parallel; Said support body 101 is oppositely arranged in main body 100 both sides; Identical from same main body 100 to the support body 101 that equidirectional extends; Coupling distance has been dwindled in the setting of said support body 101, strengthens capacitive coupling.Different according to the said first touch-control electrode 1 present position in said ITO layer; The length that said support body 101 extends to both sides from said main body 100 is different; But the summation of two support body 101 length that main body 100 both sides of the said first touch-control electrode 1 are oppositely arranged all equates, wherein is positioned at the equal in length that the support body 101 of the first touch-control electrode 10 in said ITO layer centre position extends to both sides from said main body 100; 101 of the support bodies of the first touch-control electrode 11 of position that are positioned at said edge to the third side to extension; The first touch-control electrode 12 between centre position and marginal position, its support body 101 length towards the centre position increase gradually, and its support body 101 length towards marginal position reduce gradually.And the first touch-control electrode 10 in the first touch-control electrode, the 12 relative centre positions between centre position and marginal position is symmetrical set in twos; The first touch-control electrode, 10 adjacent two first touch-control electrodes 12 with said midway are example; Both are towards support body 101 equal in length of the first touch-control electrode, 10 extensions of midway, and both are towards support body 101 equal in length of first touch-control electrodes, 11 extensions at marginal position place.Said support body 101 is different according to the position, and the arrangement mode of its support body is different, and the arrangement mode of the first touch-control electrode 10 in the nearly centre position of not disconnecting like this can be so that signal distributions be tending towards intermediateness up and down.
The said second touch-control electrode 2 is the frame type of sealing; The middle hollow hole that forms; The range upon range of added-time of two-layer ITO; The support body 101 of the part first touch-control electrode 1 is positioned at the hollow hole corresponding position of the said second touch-control electrode 2, and the support body 101 of another part first touch-control electrode 1 is positioned at the corresponding position, gap of the two adjacent second touch-control electrodes, i.e. the support body of two first adjacent touch-control electrodes 1; One of them support body 101 is positioned at the hollow hole corresponding position of the said second touch-control electrode 2, and another support body 101 is positioned at the corresponding position, gap of the two adjacent second touch-control electrodes.
Please refer to Fig. 4 and Fig. 5; Another embodiment of the present invention, it is compared to a last embodiment, between adjacent two support bodies 101 of the said first touch-control electrode 1 and the two adjacent first touch-control electrodes 1, is added with suspension piece 102; Said suspension piece 102 is with the form proper alignment of row and column; Said suspension piece 102 is a square, but is not limited to square, and it can also select other shapes such as rectangle, circle, triangle, trapezoidal, irregular figure as required.Simultaneously the said second touch-control electrode 2 also can be as required within it the gap of portion and the two adjacent second touch-control electrodes 2 add suspension piece 102.Add suspension piece 102 and can further increase capacitive coupling, reach jamproof purposes such as the better linearity and waterproof.
The present invention is not limited to the foregoing description, can select and the identical layouts of the said first touch-control electrode 1 like the said second touch-control electrode 2, adopts vertical with the first touch-control electrode 1 transversely arranged; Perhaps the second touch-control electrode shape is bar shaped, be arranged in parallel, and other selectable graphic structures; The support body that the said first touch-control electrode extends to both sides shifts to install and waits other layouts.
Double-deck ITO layouts of the present invention, the said first touch-control electrode, 1 autonomous agent 100 is extended with support body 101 to both sides, has shortened coupling distance; Obtain antijamming capabilities such as the better linearity and waterproof; And different through the first touch-control electrode, 1 residing position, the length of said support body 101 is corresponding to be increased or reduces, and realizes that signal distributions is tending towards intermediateness up and down; Obtain anti-jamming capacity such as better waterproof; And be added with suspension piece 102 at the said first touch-control electrode 1 and/or the second touch-control electrode 2, and further increase capacitive coupling, obtain the better linearity and antijamming capability.
