Embodiment
Referring to Fig. 1 to Fig. 3, shown in it is a class embodiment of the present invention, and it relates generally to a kind of touch-control array 1, and this touch-control array 1 can be used for detecting the signal of finger and time writer simultaneously.
In the touch-control array 1 shown in Fig. 1 to Fig. 3, comprise for detection of the capacitive coupling touch-control array of finger touch signal with for detection of the electromagnetic induction array of time writer signal.Certainly, capacitive coupling touch-control array and the electromagnetic induction array for detection of time writer signal are all attached on the surface of same substrate 10; And mutually insulated between capacitive coupling touch-control array and electromagnetic induction array.
Address before this in the Chinese patent application that publication number is CN102163112A, because adopting, capacitive coupling touch-control array and electromagnetic induction array form with an array, not isolation between capacitive coupling touch-control array and electromagnetic induction array, therefore, each other not in state of insulation.But, in the present embodiment, because capacitive coupling touch-control array and electromagnetic induction array need to be worked independently of one another, detect the signal that can detect separately simultaneously, therefore, the capacitive coupling touch-control array of the present embodiment and electromagnetic induction array must mutually insulateds.
As shown in Figure 3, aforesaid capacitive coupling touch-control array is mutually intersected and forms by the capacitor conductor group of both direction.Wherein, first direction capacitor conductor group 11 be parallel to each other above by two and insulate arrange first direction capacitor conductor 110 form; Second direction capacitor conductor group 12 is parallel to each other above by two and the second direction capacitor conductor 120 arranging that insulate forms.
First direction capacitor conductor group 11 is intersected mutually with second direction capacitor conductor group 12, normally 90 ° of the angles forming between first direction and second direction, and this is to adopt Cartesian coordinate to locate the needs of touch point in order to be applicable to great majority.Sometimes for example, in order to adapt to situations of some special location: adopt polar coordinates to locate touch point, also can first direction capacitor conductor group 11 intersect formed angle and be set to be greater than 0 ° with second direction capacitor conductor group 12 is mutual, but be less than 90 °.
Aforesaid electromagnetic induction array is mutually to be intersected and form by the sensor wire group of both direction.Wherein, first direction sensor wire group 21 is parallel to each other above by two and the first direction sensor wire 210 arranging that insulate forms, and second direction sensor wire group 22 is parallel to each other above by two and the second direction sensor wire 220 arranging that insulate forms.
The same with capacitive coupling touch-control array, the first direction sensor wire group 21 of electromagnetic induction array is intersected mutually with second direction sensor wire group 22, the angle forming between first direction and second direction is also 90 ° conventionally, and this is to adopt Cartesian coordinate to carry out the needs of pen with means for holding it in right position contact in order to be applicable to great majority; Sometimes for example, in order to adapt to situations of some special location: adopt polar coordinates to come pen with means for holding it in right position contact, also can first direction sensor wire group 21 intersect formed angle and be set to be greater than 0 ° with second direction sensor wire group 22 is mutual, but be less than 90 °.
On substrate 10, the setting of each capacitor conductor group 11,12 and each sensor wire group 21,22, adopts following structure:
As depicted in figs. 1 and 2, first direction capacitor conductor group 11 and first direction sensor wire group 21 are arranged on to the first surface 101 of substrate 10, second direction capacitor conductor group 12 and second direction sensor wire group 22 are arranged on to the second surface 102 of substrate.The benefit arranging is like this: under Cartesian coordinates, first direction capacitor conductor group 11 and first direction sensor wire group 21 are parallel to each other, second direction capacitor conductor group 12 and second direction sensor wire group 22 are parallel to each other, first direction capacitor conductor group 11 and first direction sensor wire group 12 can be arranged on to a surface 101 of substrate 10 simultaneously, and second direction capacitor conductor group 12 and second direction sensor wire 22 be arranged on to another surface 102 of substrate 10 simultaneously; Because first direction capacitor conductor 110 and first direction sensor wire 210 are parallel to each other, second direction capacitor conductor 120 and second direction sensor wire 220 are also parallel to each other, therefore, first direction capacitor conductor 110 and first direction sensor wire 210 can be arranged in same structural sheet 20 simultaneously, and second direction capacitor conductor 120 and second direction sensor wire 220 are arranged in another structural sheet 30 simultaneously.Like this, just can make whole touch-control array only have three-decker (as shown in Figure 2), can reduce to greatest extent the thickness of touch-control array.
Another mode is: first direction capacitor conductor group 11 and second direction sensor wire group 22 are arranged on to the first surface 101 of substrate 10, second direction capacitor conductor group 12 and first direction sensor wire group 21 are arranged on to the second surface 102 of substrate 10.The benefit arranging is like this: the different surfaces that the lead-in wire of capacitor conductor 110,120 on capacitive coupling touch-control array both direction can be distributed in to substrate 10, simultaneously, the lead-in wire of sensor wire 210,220 on electromagnetic induction array both direction is also distributed in to the different surfaces of substrate 10, can avoids lead-in wire to intersect.
Under certain situation, the resolution of capacitive coupling touch-control array and electromagnetic induction array is different, and therefore, on first direction, the distribution density of the distribution density of capacitor conductor 110 and first direction sensor wire 210 is not identical; In like manner, in second direction, the distribution density of the distribution density of capacitor conductor 120 and second direction sensor wire 220 is not identical yet; But, first direction capacitor conductor 110 and first direction sensor wire 210 can be arranged in parallel, also second direction capacitor conductor 120 and second direction sensor wire 220 can be arranged in parallel.Like this, even if there is different resolution, also can ensure that capacitive coupling touch-control array and electromagnetic induction array all carry out touch-control location based on the same coordinate system.
In other situations, in the time that first direction capacitor conductor 110 and first direction sensor wire 210 are arranged in parallel, between two adjacent first direction capacitor conductor 110, conventionally there is certain gap; Meanwhile, due to a normally straight wire of sensor wire, just can be contained among aforesaid this gap.Therefore, can adopt the mode of first direction capacitor conductor 110 and the 210 interlaced settings of first direction sensor wire, first direction capacitor conductor 110 and first direction sensor wire 210 are arranged on the same surface of substrate 10 simultaneously.In like manner, also can adopt above-mentioned mode to be parallel to each other and to be crisscross arranged on another surface of substrate 10 second direction capacitor conductor 120 and second direction sensor wire 220.Such layout, can make capacitive coupling touch-control array identical with the resolution of electromagnetic induction array.
In addition, consider different application scenarios, the material that capacitor conductor and sensor wire adopt and processing technology may be different; Therefore, even if first direction capacitor conductor group 11 and first direction sensor wire group 21 are arranged on to the same surface of substrate 10, also need between first direction capacitor conductor group 11 and first direction sensor wire group 21, insulation course 105 be set, as shown in Figure 4, so that ensure mutually can short circuit between them.In like manner, in the time that first direction capacitor conductor group 11 and second direction sensor wire group 22 are arranged on the same surface of substrate 10, due to above-mentioned same, between first direction capacitor conductor group 11 and second direction sensor wire group 22, insulation course also should be set.Such setting, obviously can make the thickness of whole touch-control array increase.
Based on different application scenarios, the material of substrate 10 can adopt glass, plastics, flexible PCB, tygon or insulation film; For example: in the occasion of the flexible touch-control array of needs, conventionally adopt plastics or insulation film as the material that forms substrate 10.To this, those skilled in the art can, according to concrete application scenario needs, adopt relevant material, and the present invention is not restricted this.In addition, conventionally use transparent material as substrate 10.Meanwhile, in order to reduce as far as possible the thickness of substrate 10, conventionally should make the thickness of substrate 10 be less than or equal to 2mm.Certainly, consider that the intensity of different substrate material and processing technology are different, therefore, aforesaid thickness should change according to the difference of material; For example: the thickness of glass substrate can be set to 0.5-1.5mm, flexible PCB can be set to 0.2-0.5mm, and tygon can be set to 1.2-2mm, and the insulation film of high-flexibility and high tensile can adopt thickness below 0.2mm etc.
Based on selecting the same reason of substrate 10 materials, in different application scenarios, the material of first direction capacitor conductor 110, second direction capacitor conductor 120 can adopt the formations such as metal forming, conductive silver paste, carbon slurry, ITO conducting film, nano-silver thread, CNT, organic conductive line, conductive rubber or enameled wire.For example: in the touch-control array being applied on display screen, can use the material of ITO conducting film as first direction capacitor conductor 110, second direction capacitor conductor 120; And on electronic whiteboard, can adopt enameled wire.Certainly, the present invention does not limit the scheme that above-mentioned various material is combined with yet.The reason of selecting with aforementioned electric capacity conductive material is the same, and the material of first direction sensor wire 210, second direction sensor wire 220 also can adopt metal forming, conductive silver paste, carbon slurry, ITO conducting film, nano-silver thread, CNT, organic conductive line, conductive rubber or enameled wire.

Conventionally; between sensor wire group 21,22, inevitably there is certain stray capacitance; the existence of this stray capacitance, can produce certain filter effect to the electromagnetic signal in sensor wire 210,220 conventionally, thereby reduces the sensitivity of touch-control array 1 to time writer signal.Well-known: the distance between two pole plates of electric capacity and electric capacity is inversely proportional to; And the distance between first direction sensor wire group 21 and second direction sensor wire group 22 is widened as much as possible, can reduce as much as possible the stray capacitance between them, thereby reduce as far as possible the filter effect of stray capacitance to electromagnetic signal.Fig. 5 and Fig. 6 are only schematically explanation, at the first surface 101 of substrate 10, also second direction conductor group 12 can be arranged on to the below of first direction conductor group 11 etc., and the present invention does not limit it.
