Embodiment
For the ease of understanding the utility model, the below is described more fully the utility model with reference to relevant drawings.Provided first-selected embodiment of the present utility model in accompanying drawing.But the utility model can be realized in many different forms, is not limited to embodiment described herein.On the contrary, providing the purpose of these embodiment is to make to disclosure of the present utility model more thoroughly comprehensively.
Need to prove, when element is called as " being fixedly arranged on " another element, can directly can there be element placed in the middle in it on another element or also.When an element is considered to " connection " another element, it can be directly connected to another element or may have simultaneously centering elements.Term as used herein " vertical ", " level ", " left side ", " right side " and similar statement are just for illustrative purposes.
Unless otherwise defined, all technology of using of this paper and scientific terminology are with to belong to the implication that those skilled in the art of the present utility model understand usually identical.The term that uses in specification of the present utility model herein is not intended to be restriction the utility model just in order to describe the purpose of specific embodiment.Term as used herein " and/or " comprise one or more relevant Listed Items arbitrarily with all combinations.
A kind of touch-screen conducting film as depicted in figs. 1 and 2, comprises transparency carrier 110, conductive layer 120 and lead-in wire electrode 130.
In embodiment, the width of conductive thread can be 0.1 μ m～10 μ m therein, and guaranteeing neither can because of the too wide light transmittance that affects the touch-screen conducting film of conductive thread, can not affect because conductive thread is too narrow the electric conductivity of touch-screen conducting film yet.The thickness of conductive thread can be 3 μ m～10 μ m, guarantees neither can because of the too thin electric conductivity that affects the touch-screen conducting film of conductive thread, also can not cause the touch-screen conducting film blocked up because conductive thread is too thick.
Above-mentioned touch-screen conducting film, due to conductive layer 120 and lead-in wire electrode 130 directly being set on transparency carrier 110, simple in structure, cost is low, has also reduced the thickness of touch-screen conducting film.
In embodiment, as shown in Figure 3, the touch-screen conducting film can comprise light shield layer 140 therein, and light shield layer 140 is arranged at the second area of transparency carrier 110, and lead-in wire electrode 130 is arranged at light shield layer 140 away from a side of transparency carrier 110.Light shield layer 140 is used for blocking lead-in wire electrode 130, and in the present embodiment, light shield layer 140 can be ink lay, and is easy to make and cost is low, specifically can be black ink layer or colored ink layer, as long as satisfy opaque and insulation.
