Abstract

The invention relates to touch input equipment, which comprises a touch region and a key region, wherein each of the touch region and the key region comprises a plurality of scanning lines and compensating lines which are respectively connected to corresponding pins of a touch chip; and the compensating lines on the touch region and the key region are conducted mutually and connected to the same pin of the touch chip. According to the touch input equipment, the compensating lines on the touch region and the key region are conducted mutually and connected to the same pin of the touch chip, so that an effective space of the chip is saved effectively; and furthermore, the time for regulating the sensitivity of the touch chip by an engineer is shortened, and the energy of the engineer is saved.

Description

A kind of touch-control input equipment

?

Technical field

the present invention relates to a kind of touch-control input equipment, refer in particular to the touch-control input equipment that has Touch Zone and key zone simultaneously.

Background technology

are recent; Along with the continuous development of science and technology, the input equipment in the electronic applications is more and more diversified, from the popular up till now full touch structure of traditional key-press formula structure; Which kind of input mode no matter, the user can both accomplish input action comparatively easily.But, because the traditional key-press structure is limited its serviceable life, so shortcoming slightly taking cost into account; And for the full touch input equipment of greatly developing for present stage; Though touching just to bump through light finger, the user can realize the input function the same with button; But for users with big fingers; If under the less relatively situation of input equipment size, be not easy the accurate position of confirming click.Therefore if can the mode that button and touch combine be imported, it is more convenient just can to bring to the user.

present stage; For the touch-control input equipment that has Touch Zone and key zone simultaneously; Because said Touch Zone and key zone include sweep trace and compensating line; So-called compensating line is meant: for the sweep trace that is positioned at Touch Zone or key zone special area such as boundary zone, the capacitive environment around it maybe be incomplete same with the capacitive environment of other sweep trace, in order to guarantee to judge accurately the position of touch points; The design engineer need handle the sweep trace of special area, promptly adds compensating line.For compensating line, its sweep trace to special area plays reference role, and its result does not participate in computing, mainly capacitive environment is played coupling.Therefore; At present in order to realize combining of key zone and Touch Zone; Last every the compensating line in above-mentioned two zones all is connected on the respective pins of chip separately; Because the bar number of compensating line usually with the arrangement of touch area upper tracer and key area on the number of button relevant, so need the pin number on the chip also more usually.Moreover, if above-mentioned two zones because the inhomogeneous influence user of the electric capacity sensitivity when operating, just need the corresponding compensating line of adjustment respectively reaching each regional purpose of adjustment, like this since, waste commissioning staff's time and efforts unavoidably.

Above problem therefore need be solved for users provide a kind of new touch-control input equipment in order to solve the shortcoming of above-mentioned appearance in .

Summary of the invention

The actual technical matters to be solved of the present invention is how a kind of touch-control input equipment of practicing thrift the useful space on the touch-control chip is provided.

are in order to realize above-mentioned purpose of the present invention; The invention provides a kind of touch-control input equipment; Comprise Touch Zone and key zone; Said Touch Zone and key zone include some sweep traces and compensating line, and it is connected respectively on the respective pins of touch-control chip, the compensating line mutual conduction on said Touch Zone and the key zone and being connected on the respective pins of said touch-control chip.

touch-control input equipment of the present invention; On a respective pins that is connected to after the compensating line conducting on said Touch Zone and the key zone on the chip; So not only effectively practiced thrift the useful space on the chip, and practiced thrift the time and efforts that the slip-stick artist adjusts its sensitivity.

Description of drawings

Fig. 1 is the connection layout according to touch-control input equipment according to the invention.

Embodiment

are further described the present invention below in conjunction with accompanying drawing and embodiment.

please refer to shown in Figure 1; Touch-control input equipment 1 of the present invention; Comprise Touch Zone 11 and key zone 12, said Touch Zone 11 includes some sweep traces and compensating line with key zone 12, and it is connected respectively on the respective pins of touch-control chip 2.

said Touch Zone 11 is provided with the sweep trace on the both direction; Be respectively directions X and Y direction; Wherein the sweep trace on the directions X is connected on the respective pins of touch-control chip 2 successively, and promptly sweep trace X1, X2...Xn are sequentially connected on corresponding each pin of touch-control chip 2 successively; Sweep trace on the Y direction also is connected on the corresponding pin of said touch-control chip 2 successively, and promptly sweep trace Y1, Y2...Yn are sequentially connected on corresponding each pin of touch-control chip 2 successively.Be equipped with compensating line Dx1 and Dx2 near first sweep trace X1 and near last root sweep trace Xn place on the directions X of said Touch Zone 11, promptly compensating line Dx1 be set at the place, periphery of first sweep trace X1; In the end place, the periphery of a sweep trace Xn is provided with compensating line Dx2; In like manner, also be provided with compensating line Dy1 and Dy2 near first sweep trace Y1 and on the said Y direction, promptly compensating line Dy1 be set at the place, periphery of first sweep trace Y1 near last root sweep trace Yn; In the end the periphery of sweep trace Yn place is provided with compensating line Dy2, through above-mentioned setting, is being also to have two compensating line Dx2 and Dy1 between last root sweep trace Xn and the first sweep trace Y1 on the Y direction on the directions X between the both direction just; Then with compensating line Dx1 all on the above-mentioned Touch Zone 11 and Dx2 and Dy1 and Dy2 mutual conduction and be connected on the respective pins of said touch-control chip 2.

said key zone 12 mainly comprises induction region 121 and compensatory zone 122, and the structure of the structure of said induction region 121 and said compensatory zone 122 cooperatively interacts, and said compensatory zone 122 is positioned at the periphery of said induction region 121.Draw sweep trace S1 on the said induction region 121 and be connected on the respective pins on the said touch-control chip 2; Said compensatory zone 122 is drawn compensating line D1; And be connected to said Touch Zone 11 on corresponding that root pin on the touch-control chip 2 that is connected with Dy2 of all compensating line Dx1 and Dx2 and Dy1, no matter be on the Touch Zone 11 promptly or the compensating line on the key zone 12 all is connected on the corresponding pin of said touch-control chip 2.

touch-control input equipment of the present invention; When realizing that key zone and Touch Zone combine; And guaranteed that the compensating line on said two zones all is connected on the corresponding pin on the chip; So not only effectively practiced thrift the useful space on the chip, and the commissioning engineer just can adjust the sensitivity in said two zones through adjustment that pin on the said chip, practice thrift the time and efforts of adjusting its sensitivity.
