Among the embodiment down below, will be with capacitance type touch-control panel as embodiment, the those of ordinary skill in any affiliated technical field should know that capacitance type touch-control panel is not in order to limit the present invention.
Fig. 1 is the synoptic diagram of the touch-control sensing device of one embodiment of the invention.In the present embodiment, touch-control sensing device 100 comprises a contact panel 110 and a touch control controller 120.Contact panel 110 comprises a plurality of touch-control blocks 112, and each touch-control block 112 comprises a 112a of first and a second portion 112b.Touch control controller 120 comprises a drive wire 122a and many sense line 124a.Drive wire 122a couples the 112a of first of each touch-control block 112, and the corresponding respectively second portion 112b that couples touch-control block 112 of sense line 124a.Wherein touch control controller 120 is exported a drive signal T1 through drive wire 122a and is given the 112a of first, and receives a plurality of transducing signal R1 that produced according to drive signal T1 through sense line 124a.Thus, touch control controller 120 just can confirm that a touch coordinate of one of corresponding touch-control block 112 (for example is the coordinate of corresponding touch-control block 112 ' (x1, y1)) according to transducing signal R1.In the present embodiment, drive signal T1 is coupled to second portion 112b to produce corresponding transducing signal R1 through the 112a of first.In addition, the touch-control block 112 of present embodiment is man-to-man relation with touch coordinate.For instance, because the number of the touch-control block 112 of Fig. 1 is four, so altogether corresponding four different touch coordinate.In other words; As long as 112a of first or second portion 112b that finger F 1 is touched are the touch-control blocks 112 ' that belongs to identical; Those touchings all can correspond to identical touch coordinate (x1, y1), so with different with the mode of the touch coordinate of definite touch position by interpolation method.
In addition, in the present embodiment, touch control controller 120 can comprise that one drives a module 122 and a sensing module 124.Drive module 122 according to a control signal S
COutput drive signal T1, and through drive wire 122a drive signal T1 is sent to the 112a of first of touch-control block 112.124 of sensing modules are to receive transducing signal R1 through sense line 124a, and produce a touching information I1 according to transducing signal R1, and wherein transducing signal R1 produces according to drive signal T1.In addition, the touch control controller 120 of present embodiment comprises that also one handles module 126, and it couples touch module 122 and sensing module 124.As shown in Figure 1, handle module 126 output control signal S
CGive to drive module 122, and confirm that according to touching information I1 a touch coordinate of contact panel 110 (for example is touch coordinate (x1, y1)).
In detail, the touch-control block 112 of present embodiment is the design of adopting button (button type), so sensing module 124 can detect the touching state of each touch-control block 112, to reach the effect of true touch-control (true touch).Wherein touch-control block 112 can be the function key of electronic installations such as mobile phone.As shown in Figure 1, the 112a of first of each touch-control block 112 comprises annular C1, and the second portion 112b of each touch-control block 112 comprises annular C2, wherein annular C1 and the concentric coplane of annular C2.Be different from the contactor control device of conventional keys design; The touch-control block 112 of present embodiment is to utilize an end (being 112a of first or annular C1) to receive drive signal T1, and the other end (being second portion 112b or annular C2) transmits transducing signal R1 to reach the sensing mode of mutual inductance (mutual-sensing).In detail; Because the 112a of first of touch-control block 112 is not coupled in second portion 112b; And the 112a of first receives the drive signal T1 from drive wire 122a; Second portion 112b then is through sense line 124a output transducing signal R1, so touch control controller 120 can be accomplished the capacitor C of each 112a of first in proper order by the mode of mutual inductance
