Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

As depicted in figs. 1 and 2, a kind of single-point that the utility model embodiment provides adds gesture capacitive touch screen 1, comprise glass substrate 11 and the ink layer 12 on glass substrate 11 is set, the one side of ink layer 12 is arranged on glass substrate 11, another side is provided with ITO layer 13, on ITO layer 13, be provided with the ITO control zone 14 for operating control, the interior etching in ITO control zone 14 has many for determining the ITO circuit 15 of reference mark coordinate position.On ink layer 12, be also provided with ITO and set up district 16, ITO sets up in district 16 and is provided with the etching region 17 for eliminating static, and ITO control zone 14 and ITO set up between district 16 and make ITO control zone 14 and ITO set up district 16 separately by isolated area 18.When 1 act of people's touch-screen, due to the existence of people's bulk electric field, can cause the variation of electric charge in the interior ITO circuit 15 in ITO control zone 14, by the electric charge changing in ITO circuit 15 is calculated, thereby determine the position touching, and then realize the function that touch-screen 1 single-point operation is controlled.Touch-screen 1 can produce static charge in the process of using, touch-screen 1 is produced the phenomenon of electrostatic breakdown after static charge focuses on certain degree, thereby affect the normal use of touch-screen 1, for fear of this situation, occur, on ink layer 12, be provided with ITO and set up district 16, for absorbing, collect static charge, making static charge can concentrate on ITO sets up in district 16, and set up in district 16 and arrange and form etching region 17 by exposure or etched mode at ITO, the interior ITO conductive material in etching region 17 is all etched, in it, there is no ITO, therefore just the ITO of original closure being set up to district 16 cuts, avoided the situation of electrostatic screening to occur.And etching region 17 is set up in district 16 at ITO and formed a ground wire, ITO can be set up to the static charge of collecting in district 16 to be delivered in time on the shell of equipment, and finally eliminate, thereby avoid the situation of electrostatic breakdown on touch-screen 1 to occur.It can be rectangle, trapezoidal, polygon etc. that ITO sets up in district 16 etching region 17 arranging, and concrete shape can arrange according to concrete requirement.Because setting up district 16, ITO control zone 14 and ITO can both conduct electricity, in order to prevent that both are short-circuited, just at ITO control zone 14 and ITO, set up and between district 16, be provided with isolated area 18, both are separated, guaranteed that ITO control zone 14 controls the stability of function and ITO and set up district 16 and absorb the stability of static charge function.

The single-point that the utility model provides adds gesture capacitive touch screen 1, is arranged on the ink layer 12 on glass substrate 11 and is provided with ITO layer 13, is provided with the ITO control zone 14 for operating control on ITO layer 13, the function of controlling for realizing operation.Because having static charge in use, touch-screen 1 produces, by ITO on ink layer 12, set up district 16, for absorbing the static charge of generation, improved the antistatic ability puncturing of touch-screen 1, simultaneously at ITO, set up and in district 16, offer etching region 17, making originally closed ITO set up district 16 is cut off, avoided the situation of electrostatic screening to occur, and, etching region 17 is set up and in district 16, is formed a ground wire at ITO, can in time static charge be derived, prevent that static charge is concentrated, guarantee the reliability that touch-screen 1 is used.

Particularly, as depicted in figs. 1 and 2, ITO control zone 14 is closed rectangle, and ITO circuit 15 is isosceles triangle and is arranged in ITO control zone 14.According to the design needs of product, just ITO control zone 14 is arranged rectangular, and ITO circuit 15 is to isosceles triangle is arranged in its region, like this, when people's finger touch is interior to ITO control zone 14, just can cause the variation of electric charge on ITO circuit 15, the ITO circuit 15 that isosceles triangle is arranged has different charge variation values, by computing formula, just can determine the coordinate position of touch, and then realize the function that single-point operation is controlled.Certainly, understandably, the shape that ITO control zone 14 arranges also can, according to different equipment requirements, be arranged to as other shapes such as triangle, polygon, circles, to meet the request for utilization under different situations.

Particularly, as shown in Figure 1 to Figure 3, isolated area 18 encloses the outside that is arranged at ITO control zone 14, and ITO sets up district 16 and encloses the outside that is arranged at isolated area 18.Because setting up district 16, ITO control zone 14 and ITO can both conduct electricity, by such setting, isolated area 18 encloses whole ITO control zone 14, and isolated area 18 is non-conductive, therefore, it can be set up district 16 by ITO control zone 14 and ITO and keeps apart, and avoids being short-circuited between the two and affects the normal use of touch-screen 1.

Particularly, as depicted in figs. 1 and 2, etching region 17 is arranged on ITO sets up the bottom in district 16.Due to the certain rule request of being designed with of whole touch-screen 1, therefore, in the present embodiment, according to the needs of actual design situation, just etching is arranged on to ITO and sets up the bottom in district 16, be convenient to processing and manufacturing.Certainly, understandably, also can be according to other designing requirement, etching region 17 is arranged on to other places such as top that ITO sets up district 16, side, can realize equally and ITO is set up to static charge in district 16 lead away, guaranteed the reliability that touch-screen 1 is used.And the number that etching region 17 arranges is also not only confined to one, can also be set to two, the number of three or more according to concrete requirement.

Preferably, as shown in Figure 1, etching region 17 is rectangular.The ITO of whole closure set up to district 16 separates and ITO set up outside the functional requirement that the static charge in district 16 leads away having met, etching region 17 is designed to rectangle, easily production and processing, has reduced whole touch-screen 1 production cost, has improved production efficiency.

The utility model also provides a kind of electronic equipment, comprises that above-mentioned single-point adds gesture capacitive touch screen 1.Because single-point adds gesture capacitive touch screen 1, there is higher antistatic breakdown capability, there will not be the image of electrostatic screening, therefore, improved the reliability of the electronic equipment use that adopts this kind of single-point to add gesture capacitive touch screen 1.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace or improvement etc., within all should being included in protection domain of the present utility model.
