Embodiment

Hereinafter, describe preferred embodiment of the present utility model in detail with reference to accompanying drawing.Note, in this instructions and accompanying drawing, thering is the structural element of identical function and structure in fact and be labeled with identical label, and the repeat specification of these structural elements is omitted.

< the first embodiment >

Fig. 1 (a) shows according to the pad pasting of the first embodiment of the present utility model and has the view of the electronic equipment of capacitive touch screen.Fig. 1 (b) shows the view of the lip-deep pad pasting of the capacitive touch screen that is attached at electronic equipment.

In Fig. 1 (a), electronic equipment 100 has capacitive touch screen 110, electronic equipment 100 is for example smart mobile phone, panel computer or control desk, the window area in the middle of capacitive touch screen 110 comprises and the circle frame region around window area.Other regions except bus 210 regions all transparent pad pasting 200 will be attached on the surface of capacitive touch screen 110, to prevent that capacitive touch screen 110 is scratched and reduces the risk that capacitive touch screen 110 breaks.Wherein, bus 210 regions can be translucent or transparent, will carry out after a while the detailed description of bus 210.

Preferably, pad pasting 200 customizes for specific electronic equipment 100, that is to say size and all capacitive touch screens 110 of very applicable electronic equipment 100 of profile of pad pasting 200.But, pad pasting 200 also can user on the basis of the pad pasting of common-use size and shape voluntarily cutting obtain.

User can be on the free-hand surface that pad pasting 200 is attached to capacitive touch screen 110 to common pad pasting, but user also can utilize some servicing units to help attach operation.Attaching in operation, size, profile, layout and the various device (such as physical button, loudspeaker and/or camera) etc. of the size of pad pasting 200, profile and reserved hole etc. and capacitive touch screen 110 can help user aim at and locate.

Be provided with translucent or transparent bus 210 at the ad-hoc location of pad pasting 200.Bus 210 is formed at the inside of pad pasting 200, will describe the composition and structure of pad pasting 200 and bus 210 thereof after a while.Except inner bus 210, other parts of pad pasting 200 are all dielectric.

As shown in Fig. 1 (b), in the time that pad pasting 200 is attached on the surface of capacitive touch screen 110, bus 210 has covered a part for the window area of capacitive touch screen 110, and has covered a part for the capacitive touch screen adjacent with this part 110 frame region.Bus 210 is known as B end hereinafter in one end of window area, bus 210 is known as C end hereinafter at the other end of frame region.The lower frame region part of C end is idle frame region part, that is to say that frame region part under C end is less than the functional device such as fixing return key or the Menu key in position.

In Fig. 1 (b), pad pasting 200 is illustrated as not covering the All Ranges of capacitive touch screen 110.But those skilled in the art easily recognizes, pad pasting 200 also can cover the All Ranges of capacitive touch screen 110 substantially.In addition, on pad pasting 200, also can reserve various holes.

When capacitive touch screen 110 is presenting one or more virtual keys away from the position of bus 210, and user press...withes one's finger and presses when one of them virtual key, and the effect that pad pasting 200 plays and common pad pasting are as good as.Virtual key herein can be also virtual icon, and situation is similar hereinafter.

When capacitive touch screen 110 is in the time that B end position presents a virtual key, this virtual key is set to bus 210 overlapping at least in part.Overlapping position and area are unrestricted, and they are only subject to the physical constraints of the factor such as resolution and judgment threshold of capacitive touch screen 110.Bus 210 does not occur overlapping with two or more virtual keys simultaneously.For example, this virtual key can be of arranging in virtual key nearest from frame, bus 210 not with this row's virtual key in contiguous virtual key overlap, and bus 210 does not extend to any one of arranging in virtual key close to frame time and overlaps.In the time that user directly press...withes one's finger pressure B end position, in the coupling capacitance that the existence of bus 210 is equivalent to form at script user finger and the sensing part in capacitive touch screen 110, inserted a slice electric conductor, result has occurred that between user's finger and sensing part user point the equivalent circuit structure that the coupling capacitance that forms with bus 210 and bus 210 are connected with the coupling capacitance of sensing part formation.Under the high frequency low voltage signal condition of work of capacitive touch screen 110, this structure is conducting, so the testing circuit in capacitive touch screen 110 detects the electric current on the sensing part corresponding with the part of bus 210 in window area and runs off, this makes all areas of the part of bus 210 in window area all be identified as contact area, and virtual key is just touched naturally.In the time that user's finger presses area has exceeded the B end area of bus 210, the situation of the area exceeding when without bus, be naturally identified as contact area, the contact area of the contact area that this exceeds and the part of bus 210 in window area is cumulative, still makes virtual key be touched smoothly.

And press C end position and finger while not being pressed into capacitive touch screen 110 window area when user press...withes one's finger, due to the impact of people's bulk electric field, originally be that the C of the bus 210 of equipotential system holds the electromotive force of B end to change to occur difference, therefore user's finger holds the part that is pressed to form coupling capacitance with the C of bus 210, and the part of bus 210 in window area forms coupling capacitance with the sensing part in capacitive touch screen 110 simultaneously.There is the equivalent circuit structure that these two coupling capacitances and the resistance between them are in series in result, resistance is wherein that the coupling part that the C end of bus 210 is pressed between part and the part in window area forms between user's finger and sensing part.Under the high frequency low voltage signal condition of work of capacitive touch screen 110, this structure is also conducting, so the testing circuit in capacitive touch screen 110 detects the electric current on the sensing part corresponding with the part of bus 210 in window area and runs off, this makes all areas of the part of bus 210 in window area still be identified as contact area, and virtual key is still touched smoothly.

In the first embodiment of the present utility model, except by adjust software particular virtual button be set to overlapping at least in part with bus 210, can also bus 210 be set to particular virtual button overlapping at least in part by adjusting pad pasting 200.

Although Fig. 1 (a) and Fig. 1 (b) are depicted as pad pasting 200 after being attached on capacitive touch screen 110 surfaces, pad pasting 200 has covered whole window area, and cover the part frame region of window area periphery, but in a variation of the first embodiment, pad pasting 200 areas are less, can only window area, cover part and the part frame region adjacent with this part visual window region, the wherein setting of bus 210, bus 210 and the window area of capacitive touch screen 110 and the position relationship of frame region, and the effect of bus 210 is all similar with the first embodiment, do not repeat them here.In another variation of the first embodiment, on capacitive touch screen 110 surfaces, can attach the pad pasting 200 of multiple small sizes, for example, at a small size pad pasting 200 of the each attaching in the relative both sides of window area.

Utilize the first embodiment of the present utility model, the virtual key that user's finger can present in frame region or near touch control capacitance formula touch-screen 110 boundary line of window area and frame region, thus the occlusion issue of finger to capacitive touch screen solved.

Further, the first embodiment of the present utility model realizes by pad pasting 200, gives the extra volume increasing of electronic equipment and the extra weight increasing almost negligible.

Further, just as common pad pasting, the first embodiment of the present utility model does not affect the use of various devices on electronic equipment substantially.

Further, the region of pad pasting 200 except bus 210 is transparent, and bus 210 regions are translucent or transparent, will drop to minimum on the impact of user's visual effect.

Further, the first embodiment of the present utility model does not use entity key, has continued the design original intention of the electronic equipment with capacitive touch screen.

In addition, along with mobile electronic device more and more gentlier, more and more thinner development trend, the capacitive touch screen above it is also more and more fragile, more and more easily damaged, particularly in the time that user plays games, because user can strengthen the dynamics of pressing unconsciously.Utilize the first embodiment of the present utility model, user can manipulate the virtual key on capacitive touch screen in the frame region more solid than window area, thereby has reduced the damage probability of capacitive touch screen.

The filling block of these distributions has reduced the light transmission rate in non-conductive region of pad pasting, thereby in the case of the part light transmission rate in non-conductive region of having sacrificed pad pasting, make that difference between the light transmission rate in non-conductive region and the light transmission rate in bus region is little can not be found out to user.So just, kept the uniformity consistency of pad pasting printing opacity.

The shape of filling block is unrestricted, for example, can be rectangle or triangle.All filling blocks can be same shapes, but can be also different shapes.For example, can there is different shapes at the filling block of diverse location.

The distribution mode of filling block is unrestricted, and for example filling block can distribute equably.And in equally distributed this situation of filling block, the arrangement mode of filling block is unrestricted, for example, it can be the arrangement mode of chessboard formula.

Can not conduct having considered that the present art, the filling block of making filling block can not conduct each other, between bus and filling block and after filling block is separated by and too far do not have required effect, in one example, the minimum distance of any two adjoining filling blocks is more than or equal to 10 microns and be less than or equal to 5 millimeters, and any bus and the minimum distance that is adjacent any one near filling block are more than or equal to 10 nanometers and are less than or equal to 5 millimeters.

As for the size of filling block, after having considered to make the present art of filling block, the size of filling block is more than or equal to 10 microns and takes advantage of the scope of 10 microns in one example.From keeping the uniformity consistency of pad pasting printing opacity and not affecting the normal running equal angles of bus, the size of filling block is the smaller the better.But the upper dimension bound of filling block is unrestricted, it is only subject to the physical constraints of the factors such as the spacing of virtual key or virtual graph target size, position and spacing and bus.

All filling blocks can be same sizes, but can be also different sizes.For example, can be of different sizes at the filling block of diverse location.
