Array type touch sensitive surface module can be divided into self-tolerant (self capacitance) and hold mutually the large class of formula (mutual capacitance) two.Figure 14 shows self-tolerant touch sensing 120, self-tolerant touch sensing 120 is to carry out sensing with X-axis and Y-axis, scan mode can be first to sweep X-axis to sweep Y-axis again, or first sweep Y-axis and sweep again X-axis, when pointer 12 touching self-tolerant touch sensing 120, the pumping signal Srf that pointer 12 is launched will increase the analog digital conversion value (ADC) of X-axis and the ADC of Y-axis near touch position, the microprocessor of self-tolerant touch sensing 120 calculates the maximal value of the ADC of X-axis and Y-axis, and then finds out touch position.Figure 15 shows mutual appearance formula touch sensing 130, an axle input drive signal wherein, another axle carries out sensing, suppose X-axis input drive signal, Y-axis is carried out sensing, when the mutual appearance formula touch sensing 130 of pointer 12 touching, the pumping signal Srf that pointer 12 is launched will increase the ADC of X-axis and the ADC of Y-axis near touch position, appearance formula touch sensing 130 is sequentially to each line of induction input drive signal in X-axis mutually, during line of induction X1 input drive signal in 130 pairs of X-axis of mutual appearance formula touch sensing, mutually in 130 pairs of Y-axis of appearance formula touch sensing, all lines of induction carry out sensing and judge whether to be greater than the maximal value of preset critical, while following the line of induction X2 input drive signal in 130 pairs of X-axis of mutual appearance formula touch sensing, mutual appearance formula touch sensing 130 carries out sensing to the lines of induction all in Y-axis equally and judges whether to be greater than the maximal value of preset critical, by that analogy.All lines of induction in X-axis all complete after driving, then to Y-axis input drive signal and to X-axis, carry out sensing, finally can obtain an overall maximum, and the X-axis at this overall maximum place and Y-axis are the coordinate of pointer 12.
Figure 16 a to 16c explanation the present invention utilizes pumping signal Srf to make the line of induction in touch sensitive surface module 14 discharge and recharge signal and changes.
In Figure 16 a, waveform 142 be expression when there is no object touch mode capacitive Trackpad, the Trackpad line of induction discharge and recharge signal.When finger contact capacitive touch control plate, the signal that discharges and recharges of the Trackpad line of induction is as shown in waveform 143.By Figure 16 a, can be found out, while having finger contact Trackpad, the Charge-discharge wave shape amplitude of the Trackpad line of induction diminishes.
In Figure 16 b, waveform 144 is pumping signal Srf, and the signal that discharges and recharges that is energized the Trackpad line of induction of signal 144 impacts is as waveform 145.When touch sensitive surface module 14 does not receive the pumping signal Srf from pointer 12, discharge and recharge signal as shown in waveform 142, when touch sensitive surface module 14 receives pumping signal Srf, if the corresponding charging signals of the falling edge of pumping signal Srf inclined-plane, and during the corresponding discharge signal of rising edge inclined-plane, as shown in waveform 144 and 145, discharge and recharge signal 145 and occur voltage amount of decrease effect, through touch sensitive surface module 14 demodulation, discharge and recharge after signal, the ADC value of its acquisition rises, its effect is similar to the signal intensity that discharges and recharges that finger contact produces, as shown in waveform 143.Touch sensitive surface module 14 can detect according to such variation the position of pointer 10.
Contrary, as shown in Figure 16 c, if the rising edge of pumping signal Srf146 is corresponding charging signals inclined-plane, and during the corresponding discharge signal of falling edge inclined-plane, discharge and recharge signal system and as shown in waveform 147, occur voltage amplification effect, through touch sensitive surface module 14 demodulation, discharge and recharge after signal, the ADC value of its acquisition declines, and is different from the effect that finger contact produces.Therefore, set the corresponding charging signals of the rising edge inclined-plane of pumping signal Srf, and the corresponding discharge signal of falling edge inclined-plane, by rising or the decline of ADC value, can make touch sensitive surface module 14 further tell pointing or pointer liking of touching.In different application, touch sensitive surface module can in response to tell touching to as if finger or pointer and the different treatment scheme of carrying out, for example, when pick out touching to as if during pointer, improve the coordinate resolution of touch-control module.
More than illustrate and be not intended to restriction and discharge and recharge the relation between signal and ADC value.In other embodiment, in response to different signal handlers, may be also that corresponding A DC value rises when discharging and recharging signal and occurring voltage amplification, or when discharging and recharging signal and occurring voltage amount of decrease, the decline of corresponding A DC value.
Pumping signal Srf can be adjusted with the phase relation that discharges and recharges signal.For example, make the central point A on the corresponding charging signals of the falling edge inclined-plane of waveform 144 in Figure 16 b, and the central point B on the corresponding discharge signal of rising edge inclined-plane, now can obtain the maximum of signal amount of decrease.Or, make the central point A on the corresponding charging signals of the rising edge inclined-plane of waveform 146 in Figure 16 c, make the central point B on the corresponding discharge signal of the falling edge inclined-plane of waveform 146, now can obtain the maximum of signal amplification.
In Figure 16 a～c, discharge and recharge signal system and take triangular wave as example, other waveform also can obtain identical effect.Figure 17 shows the signal that discharges and recharges of pumping signal Srf and another kind of waveform, and wherein waveform 150 is pumping signal Srf, and waveform 152 and 154 is for discharging and recharging signal.When pointer 12 is not touched touch sensitive surface module 14, on touch sensitive surface module, the line of induction discharges and recharges signal as shown in waveform 152, when pointer 12 is touched touch sensitive surface modules 14 and is sent pumping signal Srf, the the discharging and recharging signal and will change of the position that pointer 12 is touched, if the falling edge of pumping signal Srf is positioned at charging time-histories, and rising edge is positioned at electric discharge during time-histories, discharge and recharge signal 154 and will occur voltage amount of decrease effect, its effect produces as finger contact discharges and recharges signal intensity.As the rising edge of pumping signal Srf is positioned at charging time-histories, and falling edge is positioned at electric discharge during time-histories, discharges and recharges signal 154 and will occur voltage amplification effect, and its effect is different from the signal intensity that discharges and recharges that same finger contact produces.
Above-mentioned explanation by Figure 16 and 17 can be understood, and the present invention utilizes pumping signal to make the signal that discharges and recharges of touch sensitive surface module occur changing, no matter this change is to make voltage amplification or amount of decrease, can allows touch sensitive surface module judge object and approaches or touch.And the pumping signal Srf that pointer emits is not limited to square wave, can also be with triangular wave, or the waveform of other form.
The emitted energy of the pumping signal Srf that pointer 12 is launched need just be adjusted, if just when the too high pointer 12 of emitted energy contacts touch panel module 14, be not sensed, if emitted energy too low may occur cannot sensing phenomenon.Emitted energy can be adjusted to the intensity needing by crest voltage and the responsibility cycle of adjusting pumping signal Srf than (duty).Figure 18 shows the pumping signal Srf of out of phase and different responsibility cycle ratio, discharge and recharge the waveform of signal as shown in 160, the pumping signal Srf of 270 °, phase place of take is example, larger while the voltage amount of decrease effect of touch sensitive surface module 14 being 25% with respect to the responsibility cycle of pumping signal Srf than TH/ (TH+TL2) when the responsibility cycle of pumping signal Srf is 50% than TH/ (TH+TL1), as shown in waveform 162 and 164, in other words, the responsibility cycle of pumping signal Srf when being 50% emitted energy larger while being 25% than responsibility cycle ratio.In like manner, the emitted energy when responsibility cycle of pumping signal Srf is 16.7% than TH/ (TH+TL3) as shown in waveform 166 is lower while being 25% than responsibility cycle ratio, the voltage amount of decrease effect of touch sensitive surface module 14 is also reduced relatively, the emitted energy when responsibility cycle of pumping signal Srf is 12.5% than TH/ (TH+TL4) is lower while being also 16.7% than responsibility cycle ratio, the voltage amount of decrease effect of touch sensitive surface module 14 is also reduced relatively, as shown in waveform 168.The method of the responsibility cycle ratio of adjustment pumping signal Srf is a lot, for example, the partial pulse of pumping signal Srf is covered.With reference to the waveform 162 and 164 of Figure 18, after being covered than the pulse 170 and 172 that is 50% pumping signal Srf, responsibility cycle can obtain responsibility cycle than the pumping signal Srf that is 25%.
Above embodiment is used for illustrative purposes only, but not limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, can also make various conversion or variation.Therefore, all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
