Description
Technical field
The utility model belongs to a kind of technical field of contact panel, particularly be meant a kind ofly to produce the gradient phenomenons and can prevent the contact panel of the surface capacitance type that electric current is cancelled each other, so that this contact panel has the function that multiconductor is judged in same level or vertical different contact resistance.
Background technology
In the electronic equipment development history, the appearance of inputting interfaces such as keyboard, mouse and Trackpad has solved the problem of input control.But, these inputting interfaces take up space not little, and for example, half volume of notebook computer or mobile phone is all occupied by keyboard.If can economize the lower keyboard space, natural energy promotes the product portability, and the most feasible mode is exactly directly to operate with touch control manner in panel.Contact panel can replace most of keyboards, mouse function really, and invests user more intuition, operating experience easily; Substitute keyboard with bigger panel, can also design more frivolous, fashion moulding; Add and adopt solid-state panel technology fully, need not worry the problem of mechanical component faults such as keyboard, pulley.
Distinguish contact panel from know-why, it can be divided into resistive technologies contact panel, capacitance technology contact panel, infrared technology contact panel, surface acoustic wave technique contact panel, electromagnetic technique contact panel and optical technology contact panel etc.The wherein accurate positioning of electric resistance touch-control panel, but its price is quite high, and be afraid of to scrape rapid wear.Infrared technology contact panel cheap, but its housing is frangible, is easy to generate light and disturbs distortion under the curved surface situation; And surface acoustic wave touch panel has solved the various defectives of touch screen in the past, and is clear uprising, is suitable for various occasions, and shortcoming is that water droplet, the dust of panel surface can make the blunt of contact panel change, does not even work.Therefore at present having concurrently under durability, cost, reaction velocity and the convenience considering of contact panel exploitation, electric resistance touch-control panel and capacitance type touch-control panel become the main force's product on the market.
In recent years, be subjected to the intimate touch-control interface of smart mobile phone, allow smart mobile phone have an opportunity to win more people's favor.And the appearance of multi-point touch function (as smart mobile phones such as iPhone, HTC) more causes the new revolution of using the interface, and the user can use the electronic product of using this multi-point touch panel in more intuitive mode.
But, release for some time at aforementioned multi-point touch control type smart mobile phone, a barrage of similar concept product occurs on the market but do not see yet, can seem and exist quite high together threshold really in the practice of technology.On market, there is multiple touch technology at present, has only capacitive technologies to be expected to realize function of multi-spot touch.See further that again capacitance touching control can be divided into surface capacitance type (Surface Capacitive) and two kinds of practices of projected capacitive (Projective Capacitive) again;
With the technology practice of surface capacitance type wherein, it is a conventional surface capacitance type touch-control panel as shown in Figure 1.The hardened layer 14 that this contact panel 10 is used by a transparency carrier 11, a transparency conducting layer 12, an electrode pattern layer 13 and an insulation protection is constituted; wherein this transparency carrier 11 can be glass, plastic cement; this electrode pattern layer 13 is by forming the periphery part that the relative Y lateral electrode 132 with two of two relative X lateral electrodes 131 that surrounds into rectangle is formed at this transparency conducting layer 12, in order to compensate the curve distribution of the electric field on this transparency conducting layer 12.In addition, as shown in Figure 2, lead 151,152,153,154 outside four corners of this contact panel 10 respectively connect with one joins, and exchanges sensing signal (AC1, AC2, AC3, AC4) in order to receive one respectively, for the position usefulness that measures a contact P on the contact panel 10.When real work, these interchange sensing signals AC1, AC2, AC3, AC4 are identical ac square wave or the string wave voltage signal of amplitude size, and respectively connect this moment respectively has an electric current I 1, I2, I3 and I4 to pass through on the outer conductor 151,152,153,154.By measuring current change quantity Δ I1, Δ I2, Δ I3 and the Δ I4 before this contact P occurs and when occurring that each connects outer conductor 151,152,153,154, the X of P position, this contact, Y coordinate just can be calculated according to following formula:
X＝(ΔI3+ΔI4-ΔI1-ΔI2)/(ΔI1+ΔI2+ΔI3+ΔI4)
Y＝(ΔI1+ΔI4-ΔI3-ΔI2)/(ΔI1+ΔI2+ΔI3+ΔI4)
Therefore on operational architecture, system can produce a uniform electric field at transparency conducting layer 12, when the electric capacity charge effects can appear in the finger touch panel, form capacitive coupling between each transparent X of panel top electrode patterned layer 13, Y lateral electrode 131,132 and finger, and then generation capacitance variations, controller just can calculate contact position according to size of current as long as measure four corner strength of current.
Because it causes electrostatic field to change by finger contact contact panel and detects, wherein the single-point touch capacitive technologies is quite ripe in fact, just surface capacitance type (Surface Capacitive).This Technical Architecture is more simple, only needs a transparency conducting layer 12 to realize, and this transparency conducting layer 12 do not need special sense channel design, and periphery only need connect 4 leads 151,152,153,154 and ground wire gets final product, and production difficulty and cost all can reduce.The restriction of its maximum then is, it can't realize the multi-point touch function, mainly be because it is when the real work industry, as imposing on two simultaneously with upper contact, and when carrying out gesture motion between two contacts (as convergent-divergent, rotation or dilatory etc.), it may cancel out each other the electric current of output because of two finger positions are corresponding shape, causes the erroneous judgement of its contact or action, so existing surface capacitance type contact panel is not the desirable technique of multi-point touch.
Also therefore.Projected capacitive (Projected Capacitive) technology has just become to realize the hope place of multi-point touch.As Fig. 3 is the three-dimensional exploded view of a traditional projected capacitive touch panel.This capacitance type touch-control panel 20 is coincided from lower to upper by a transparency carrier 21, an X transparent electrode pattern layer 22, a transparent dielectric layer 23 and a Y transparent electrode pattern layer 24 and forms, wherein each forms the sensing patterns 25 (sensing element) of row/row on X and the Y transparent electrode pattern layer 22,24, in order to cooperate with other element for judging the existence of one or more contact on this contact panel 20, the sensing patterns 25 of X and Y transparent electrode pattern layer 22,24 and join wherein with a plurality of external wires 28.
Compared to surface capacitance type, projected capacitive is adopted single or multiple lift patternization (patterned) and is formed staggered sensing patterns 25 (sensing element) matrix of row/row.Thus, in the whole use life cycle, do not need just can obtain accurate position of touch, and can use thicker overlayer, can accomplish the multi-point touch operation yet by calibration.But this still belongs to suitable advanced person and complicated technology on market, the sensing mode of its screen must adopt matrix (Matrix) scan pattern of multicolumn (column) and multiple row (row), can be divided into shaft staggered formula (Axis Intersect) again but and all contact locate modes (All Points Addressable, APA) two kinds of sensing screens.More or less freely in the former practice, also lower for the requirement of computing and storage resources, if but want to realize accurate 2 touch-controls location, still adopt the detection technology of APA.
But whichsoever, with regard to present manufacturing technology, it all need use higher manufacturing technology, therefore its manufacturing cost is high, be not inconsistent the demand of actual use, be subjected to the influence of its computing, storage resources deficiency and sensing accuracy what is more, the volume production that can only be used for the small size panel of present projected capacitive touch panel, for in using, the industry (as notebook computer, industrial computer, POS system, ATM, medical equipment, monitor, game machine or the like) of large size panel, still can't effectively satisfy the demand of its multi-point touch.
In other words, because it is simple and easy and be easy to make and the production advantage cheaply that the surface capacitance type contact panel has framework, simultaneously surface capacitance type touch-control product has more dustproof, fire prevention, scratch resistant, strong durable and have an advantage such as high-res, so if can develop surface capacitance type contact panel, then can have the convenience of use and the effect of low cost concurrently with multiconductor decision-making function.

Again, another fundamental purpose of the present utility model is to provide a kind of multi-point touch structure of surface capacitance type contact panel, significantly simplifying the formation of multipoint mode contact panel, and reduces its manufacture difficulty, and can effectively reduce its cost.
The utility model comes aforesaid purpose of specific implementation and effect mainly by following technological means:
