Please refer to Fig. 6.The synoptic diagram of first embodiment when Fig. 6 scans for resistance hybrid touch control device 10 of the present invention.In the present embodiment, the resistance-type detecting has right of priority, also is that resistance hybrid touch control device 10 meeting first input voltage to electric resistance touch-control modules 11 of the present invention are to detect.The control signal Sc of resistance hybrid touch control device 10 output expressions " 00 "; This moment, I/O end XR and XL were suspension joint; I/O end YU is coupled to the first voltage source V a and I/O end YD is coupled to the second voltage source V b to produce voltage difference, and the sensed layer 112 of winning is sent toward the Y directions.In the present embodiment, the first voltage source V a is a noble potential and the second voltage source V b is an electronegative potential, so electric current flows to I/O end YD by I/O end YU.Then; The control signal Sc of resistance hybrid touch control device 10 output expressions " 01 "; This moment, I/O end YU and YD were suspension joint; I/O end XR is coupled to the first voltage source V a and I/O end XL is coupled to the second voltage source V b to produce voltage difference, and the sensed layer 112 of winning is sent toward directions Xs.In the present embodiment, because the first voltage source V a is a noble potential and the second voltage source V b is an electronegative potential, electric current flows to I/O end XL by I/O end XR.When electric resistance touch-control module 11 was detected, all first sensor pad X1～Xn and second sensor pad Y1～Ym were coupled to resistance sensing circuit 33 to the switch controlling signal Ssw that resistance hybrid touch control device 10 is exported expression " 1 " simultaneously on the capacitance touching control module 12 to allow.
So; When first sensed layer 112 is sent electricity toward the X of sensed layer 112 or Y direction, the variation that resistance hybrid touch control device 10 of the present invention utilizes first sensor pad X1～Xn and the second sensor pad Y1～Ym on the capacitance touching control module 13 to detect voltage on first sensed layer 112.For instance; When first sensed layer 112 is sent electricity toward the Y direction; There is external force to put on first substrate 111 or second substrate 131 makes first sensed layer 112 contact with second sensed layer 132; (switch controlling signal Ssw is " 1 " because all sensor pads of capacitance touching control module 13 all are coupled to resistance sensing circuit 33; Interrupteur SW 1～SWp conducting); Therefore detect the signal of this contact point through capacitance touching control module 13, resistance sensing circuit 33 just can calculate the position of this contact point in Y-axis.In like manner, when first sensed layer 112 is sent electricity toward directions Xs, detect the signal of this contact point through capacitance touching control module 13, resistance sensing circuit 33 just can calculate the position of this contact point in X-axis.
If the resistance-type detecting can detect the signal of this contact point, resistance hybrid touch control device 10 of the present invention just can skip over the condenser type detecting.If the resistance-type detecting fails to detect this contact point, resistance hybrid touch control device 10 just can carry out the condenser type detecting, also is that resistance hybrid touch control device 10 only can utilize capacitance touching control module 13 to detect.
As shown in Figure 6, when resistance hybrid touch control device 10 carried out the condenser type detecting, control signal Sc was that " 1x ", switch controlling signal Ssw are that " 0 ", enable signal EN are " 0 ".When control signal Sc is " 1x "; The I/O end YU of electric resistance touch-control module 11, YD, XR, XL all hold GND (electric resistance touch-control module 11 is closed) with being coupled to, the screen layer (shielding layer) that this moment, electric resistance touch-control module 11 can be used as capacitance touching control module 13.When switch controlling signal Ssw was " 0 ", interrupteur SW 1～SWp closed so that first sensor pad X1～Xn on the capacitance touching control module 13 and second sensor pad Y1～Ym are coupled to input end I1～Ip that corresponding main separation is selected circuit 31 separately.When enable signal EN was " 0 ", the output terminal Z that enable circuit 32 is selected circuit 31 with main separation was coupled to capacitance sensing circuit 34.Main separation is selected control signal Sm and is switched to " 0000 ", " 0001 ", " 0010 " in regular turn ... to export first sensor pad X1～Xn on the capacitance touching control module 13 and the signal of second sensor pad Y1～Ym to capacitance sensing circuit 34 via enable circuit 32 in regular turn.In other words, when carrying out the condenser type detecting, capacitance sensing circuit 34 is detected the capacitance variation of first sensor pad X1～Xn and second sensor pad Y1～Ym in regular turn.For instance; During when finger touch or near first substrate 111 or second substrate 131; Change at first sensor pad of this contact point and the electric capacity of second sensor pad; Via the detecting of capacitance sensing circuit 34, can calculate X-axis coordinate data and Y-axis coordinate data on this contact point resistance hybrid touch control device.
In brief, in complete scan each time, resistance hybrid touch control device 10 carries out the resistance-type detecting earlier; Resistance sensing circuit 33 is detected the change in voltage of Y direction and X-direction on first sensed layer 112 through second sensed layer 132, if there is not the signal that detects contact point, resistance hybrid touch control device 10 carries out the condenser type detecting; Capacitance sensing circuit 34 is detected the capacitance variation (like the order according to X1, X2, X3...Xn, Y1, Y2, Y3...Ym) of first sensor pad X1～Xn and second sensor pad Y1～Ym in regular turn.
Please refer to Fig. 7.The synoptic diagram of second embodiment when Fig. 7 scans for resistance hybrid touch control device 10 of the present invention.Second embodiment when resistance hybrid touch control device 10 scans is similar in appearance to first embodiment.In first embodiment; Resistance-type detecting is for detecting the change in voltage of Y direction and X-direction on first sensed layer 112 through second sensed layer 132; And in a second embodiment, the resistance-type detecting is for detect the change in voltage of correspondence position on first sensed layer 112 in regular turn through first sensor pad X1～Xn and second sensor pad Y1～Ym.That is to say; No matter resistance-type detecting or condenser type detecting; Switch controlling signal Ssw all is expressed as " 0 ", also is that interrupteur SW 1～SWp keeps shut and first sensor pad X1～Xn on the capacitance touching control module 13 and second sensor pad Y1～Ym are coupled to input end I1～Ip that corresponding main separation is selected circuit 31 separately.
As shown in Figure 7, control signal Sc is expressed as " 00 " in regular turn and reaches " 01 ", so that first sensed layer 112 is sent toward Y direction and directions X in regular turn; This moment, enable signal EN was expressed as " 1 ", and switch controlling signal Ssw is expressed as " 0 ", also be that main separation is selected circuit 31 the first sensor pad X1 is coupled to enable circuit 32, and enable circuit 32 was coupled to resistance sensing circuit 33 with the first sensor pad X1 again.Therefore, resistance sensing circuit 33 is detected the voltage of Y direction correspondence position on first sensed layer 112 through the first sensor pad X1, detects the voltage of directions X correspondence position on first sensed layer 112 again through the first sensor pad X1.Then; Enable signal switches to " 0 "; Control signal Sc is expressed as " 1x " and switch controlling signal Ssw is maintained " 0 ", and enable circuit 32 is coupled to the capacitance variation that capacitance sensing circuit 34 (also promptly the first sensor pad X1 is coupled to capacitance sensing circuit 34) utilizes the capacitance sensing circuit 34 detectings first sensor pad X1 to close electric resistance touch-control module 11.So just accomplish the resistance-type detecting and the condenser type detecting that utilize the first sensor pad X1 to carry out.Main separation is selected control signal Sm and is switched to " 0001 ", also is that main separation is selected circuit 31 and the first sensor pad X2 is coupled to enable circuit 32 is accomplished resistance-type detecting and condenser type detecting corresponding to the position of the first sensor pad X2 to utilize the first sensor pad X2 to repeat above-mentioned steps.By that analogy, utilizing main separation to select control signal Sm switches to all first sensor pad X1～Xn and second sensor pad Y1～Ym and repeats resistance-type detecting and the condenser type detecting that above-mentioned steps just can be accomplished resistance hybrid touch control device 10.
In other words; Like Fig. 1～shown in Figure 3; When applying a voltage in first sensed layer 112, (touching resistance hybrid touch control device 10), resistance hybrid touch control device 10 utilizes many first sensor pad X1～Xn of second sensed layer 132 and the change in voltage that many second sensor pad Y1～Ym detect first sensed layer 112.Resistance hybrid touch control device 10 change in voltage according to first sensed layer 112 are come the position of the contact point on calculated resistance/electric capacity hybrid touch control device 10.If there is not the signal detect contact point, resistance hybrid touch control device 10 is first sensed layer, 112 ground connection, and detects many first sensor pad X1～Xn of second sensed layer 132 and the capacitance variation of many second sensor pad Y1～Ym.According to the capacitance variation of many first sensor pad X1～Xn and many second sensor pad Y1～Ym, just can calculate the position of contact point on resistance hybrid touch control device 10.As shown in Figure 6; When applying a voltage to first sensed layer 112, resistance hybrid touch control device 10 can utilize whole many first sensor pad X1～Xn of second sensed layer 132 and the change in voltage that many second sensor pad Y1～Ym detect first sensed layer 112.As shown in Figure 7; When applying a voltage to first sensed layer 112, resistance hybrid touch control device 10 also can utilize one second sensor pad of one first sensor pad and many second sensor pad Y1～Ym of many first sensor pad X1～Xn of second sensed layer 132 to detect the change in voltage of first sensed layer 112 in regular turn.
