Specifically, if have target piece (such as pointing) near to or in contact with the surface of contact panel 100, point by and mutually close conducting element between form coupling capacitance, thus there is the change of capacity effect at finger near to or in contact with region, to detect the position of finger or to move.Wherein, finger can across insulator, such as overlay (cover lens), and carry out the touch control operation touching insulator outside surface, this control mode touch mode is called two-dimentional control mode touch mode.In addition, finger also can close to but do not contact contact panel to carry out suspension touch control operation, this control mode touch mode is called three-dimensional touch pattern.
In the present embodiment, the contact panel 100 with two-dimentional control mode touch mode or three-dimensional touch mode activated Fig. 1 can be selected.Fig. 2 illustrates with driving schematic diagram during two-dimentional control mode touch mode driving contact panel.Please refer to Fig. 1 and Fig. 2, when contact panel 100 enters two-dimentional control mode touch mode, perform mutual capacitance type sensing method with the first electrode 120 and the second electrode 140.Above-mentioned mutual capacitance type sensing method comprises the following steps.Input multiple first drive singal TX1 ~ TX5 to the second electrode 140a ~ 140e.Be electrically connected the first sub-electrode 122a and the second sub-electrode 122b of same first electrode 120a ~ 120e.Now, the first sub-electrode 122a of same first electrode 120a ~ 120e and the second sub-electrode 122b can export a sensing signal jointly.Multiple first sensing signal RX1 ~ RX5 is received from first electrode 120a ~ 120e.By above-mentioned mutual capacitance type sensing method, contact coordinate during target piece (such as pointing) touch contact panel 100 can be measured.Certainly, in other embodiments, above-mentioned first electrode 120 and the second electrode 140 also can perform self-capacitance sensing method, can measure contact coordinate so equally, determine according to demand.
Specifically, when carrying out two-dimentional control mode touch mode, the first sub-electrode 122a and the second sub-electrode 122b of same first electrode 120a ~ 120e are electrically connected, to form first electrode 120a ~ 120e of a strip.These the first electrode 120a ~ 120e and second electrode 140a ~ 140e can form a mutual capacitance type touch control sensing region, to provide the good linearity and accurate touch control detection.
Fig. 3 illustrates with driving schematic diagram during three-dimensional touch mode activated contact panel 100.Please refer to Fig. 1 and Fig. 3, when contact panel 100 switches to three-dimensional touch pattern, perform self-capacitance sensing method with first electrode 120a ~ 120e.Above-mentioned self-capacitance sensing method comprises the following steps.The first sub-electrode 122a of each first electrode 120a ~ 120e electrically isolated and the second sub-electrode 122b.In other words, the first sub-electrode 122a of first electrode 120a ~ 120e and the second sub-electrode 122b can export a sensing signal separately.In detail, the first sub-electrode 122a and the second sub-electrode 122b of multiple drive singal TX1 ~ TX10 to the first electrode 120a ~ 120e can be inputted.Further, multiple sensing signal RX1 ~ RX10 is received from the first sub-electrode 122a of first electrode 120a ~ 120e and the second sub-electrode 122b.By above-mentioned self-capacitance sensing method, contact coordinate during target piece (such as pointing) suspension touch control contact panel 100 can be measured.In previous embodiment, illustrate that five first electrode 120a ~ 120e and five, a second electrode 140a ~ 140e is that example illustrates, but the present invention does not limit the number of the first electrode and the second electrode.In addition, the better width being greater than first electrode 120a ~ 120e of the width of second electrode 140a ~ 140e; Such as, the width of each the second electrode is greater than the width of each the first electrode; In addition, the gap width between two adjacent second electrode is better is less than the width in the gap between two adjacent first electrode.
Specifically, when carrying out three-dimensional touch pattern, first sub-electrode 122a and the second sub-electrode 122b of first electrode 120a ~ 120e are electrically isolated from each other, to carry out self-capacitance sensing method, thus, can increase the detection-sensitive distance between contact panel and target piece under three-dimensional touch pattern, target piece does not limit and very must could realize successful touch-control near contact panel, and therefore the application of three-dimensional touch pattern can more elasticity and hommization.
In addition, when carrying out three-dimensional touch pattern, its driving method also comprises provides reference voltage to the second electrode 140.For example, can make the second electrode 140 ground connection, thus, the second electrode 140 can play the function of shielded signal interference, to promote the touch-control sensitivity of three-dimensional touch.It is worth mentioning that, as the second electrode width is greater than the first electrode, and the gap width between adjacent 2 second electrodes is less than the gap width between adjacent 2 first electrodes, then the effect of its shielded signal interference is better.
First sub-electrode 122a of first electrode 120 of Fig. 1 is made up of an area change pattern T1, and the second sub-electrode 122b is made up of an area change pattern T2.But the present invention does not limit the quantity of the area change pattern of the first sub-electrode 122a and the second sub-electrode 122b.Below will enumerate other embodiments to describe the present invention in detail.All possibility parts, will use same or analogous label to represent same or analogous component, and the part that no longer repeat specification technology contents is identical.
