Embodiment
The technical matters solved for making the present invention, the technical scheme of employing and the technique effect that reaches are clearly, be described in further detail below in conjunction with the technical scheme of accompanying drawing to the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those skilled in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Inventor studies discovery, and in self-capacitance touch-control implementation, as shown in Figure 1, touch control electrode 12 one-tenth matrix arranges, and each touch control electrode 12 is connected with touch-control IC14 by touch control electrode line 13; When touch control detection, the working method of each touch control electrode 12 is the same, when touch-control state starts, produces touch-control drive singal, be supplied to touch control electrode 12, make touch control electrode 12 with certain quantity of electric charge through touch control electrode line 13 by touch-control IC14; After touch-control occurs, the quantity of electric charge of touch-control IC14 in touch control electrode line 13 pairs of touch control electrode 12 reads, then by the change of the quantity of electric charge, can judge which or which touch control electrode 12 is touched, thus can determine the position of touch point further.Touch-control drive singal can be understood as a pulse signal, as shown in Figure 2, when touch control detection, the pulse signal that touch-control IC14 sends as shown in the figure left side to touch control electrode 12 drives touch control electrode 12, after touch-control occurs, the touch-control IC14 pulse signal read as shown in figure the right confirms the position of touch point.Each touch control electrode 12 of this detection scheme is connected with touch-control IC14, the function that each PIN corresponding with touch control electrode 12 will realize sending pulse touch-control IC14 and detect electric current, the high cost of touch-control IC14, and detect time consumption and power consumption all larger.
For solving the problem, the invention provides a kind of contactor control device, please refer to Fig. 3, it is the touch control electrode of a kind of contactor control device provided in the specific embodiment of the invention and the annexation schematic diagram of touch-control IC.As shown in the figure, this contactor control device, comprise the touch control electrode 12 of multiple mutually insulated, described touch control electrode 12 is divided into the first electrode 121 and the second electrode 122, described first electrode 121 is connected with the first electrode wires 131, described second electrode 122 is connected with the second electrode wires 132, and wherein, described first electrode 121 surrounds described second electrode 122.
Wherein, touch control electrode 12 is divided into the first electrode 121 and the second electrode 122 and distinguishes the first corresponding electrode wires 131 and the second electrode wires 132 with it, be not that structural change has been done to touch control electrode 12 or electrode wires 13, but in order to the layout optimization scheme that describes touch control electrode 12 based on the segmentation functionally of touch control electrode 12 to its complementary definition.
Optionally, described touch control electrode 12 carries out touch control detection by mutual capacitance, and described first electrode wires 131 inputs the first touch-control drive singal, and described second electrode wires 132 exports touch-control sensing signal.
It should be noted that, when carrying out touch control detection by mutual capacitance, described first electrode wires 131 inputs the first touching signals, and described second electrode wires 132 exports the optional embodiment of one that touch-control sensing signal is this programme.When carrying out touch control detection by mutual capacitance, electric field is formed between adjacent two conductors, the medium realizing detecting is provided, in this programme, limiting the second electrode wires 132, to export touch-control sensing signal be because limit the first electrode 121 and surround the second electrode 122 in this programme, so the second electrode 122 at least can not more than the first electrode 121, if the second electrode 122 exports touch-control sensing signal, the required acquisition of touch-control IC14 is relative with the number of the touch-control sensing signal calculated can be fewer, operation efficiency can be improved further, reduce energy consumption.
Otherwise, if the second electrode wires 132 inputs touch control detection signal, first electrode wires 131 exports touch-control sensing signal, so the required acquisition of touch-control IC14 is relative with the number of the touch-control sensing signal calculated can be many, but relative to the design that touch control electrode 12 each in prior art is internal loopbacks, still can effectively reduce energy consumption and time consumption.In follow-up embodiment, be all that the scheme receiving touch-control sensing signal for the second electrode 122 is described, but the function of the first electrode 121 and the second electrode 122 is inverted, and all can realize the design philosophy of this programme, be not described further in subsequent embodiment.
Further, described touch control electrode 12 carries out touch control detection by mutual capacitance, and described first electrode wires 131 inputs the first touch-control drive singal, and described second electrode wires 132 inputs the second touch-control drive singal, and described second electrode wires 132 exports touch-control sensing signal;
Wherein, the pulse sequence of described first touch-control drive singal and described second touch-control drive singal is complementary.
