Embodiment
See also Fig. 2 and Fig. 3, wherein Fig. 2 is the schematic diagram of a kind of contact panel of disclosing of one embodiment of the invention, and the concrete structure schematic diagram of the contact panel that Fig. 3 is Fig. 2 to be disclosed.As shown in Figure 3, contact panel 100 is divided into four zones, i.e. first area I, second area II, the 3rd regional III and the 4th regional IV.Wherein, first area I and second area II are transversely arranged, and the 3rd regional III and the 4th regional IV are transversely arranged; First area I and the 3rd regional III longitudinal arrangement, and second area II and the 4th regional IV longitudinal arrangement.
Drive wire X11, X12, X21, X22 ... Xn1, Xn2, X (n+1) 1, X (n+1) 2 ..., sense wire Y11, Y12, Y21, Y22 ... Ym1, Ym2, Y (m+1) 1, Y (m+1) 2 ... and sensing cell 110 is distributed in first area I, second area I I, the 3rd regional III and the 4th regional IV.Wherein, drive wire X11, the X21 among the I of first area ... cabling through a side 101 of contact panel 100, and drive wire X12, X22 among the second area II ... cabling through the relative opposite side 102 of contact panel 100; In like manner, drive wire Xn1, X (n+1) 1 among the 3rd regional III ... cabling also such as first area I through a side 101 of contact panel 100, and drive wire Xn2, the X (n+1) 2 among the 4th regional IV ... cabling also such as second area II through the relative opposite side 102 of contact panel 100.Sense wire Y11, Y21 among the I of first area ... cabling through a side 103 of contact panel 100, and sense wire Y12, Y22 among the 3rd regional III ... cabling pass first area I, and with first area I in sense wire Y11, Y21 ... the same side 103 through contact panel 100.Similarly, sense wire Ym1, Y (m+1) 1 among the second area II ... cabling through a side 103 of contact panel 100, and sense wire Ym2, the Y (m+1) 2 among the 4th regional IV ... cabling then pass second area II and through the same side 103 of contact panel 100.
That is to say, drive wire X11, X12 on the contact panel 100, X21, X22 ... Xn1, Xn2, X (n+1) 1, X (n+1) 2 ... cabling pass through respectively the relative both sides 101 and 102 of contact panel 100, with from the relative both sides 101 and 102 of contact panel 100 respectively input drive signals to drive wire X11, X12, X21, X22 ... Xn1, Xn2, X (n+1) 1, X (n+1) 2 ... drive sensing cell 110; On the contrary, sense wire Y11, Y12 on the contact panel 100, Y21, Y22 ... Ym1, Ym2, Y (m+1) 1, Y (m+1) 2 ... cabling one side 103 of only passing through this contact panel, with sensing signal that sensing cell 110 is produced by sense wire Y11, Y12, Y21, Y22 ... Ym1, Ym2, Y (m+1) 1, Y (m+1) 2 ... pass from this side 103 of contact panel.That is, contact panel 100 is by two different drive wires, drives the extremely sensing cell 110 of every row of signal such as X11 and X12 from two opposite direction X1 and X2 transmission; And by two different sense wires, such as Y11 and Y12, read the sensing signal that the sensing cell 110 of every row produces from same direction Y.
Because the sensing cell 110 of the every row among transversely arranged first area I and second area II or the 3rd regional III and the 4th regional IV transmits the driving signal by two different drive wires from two opposite direction X1 and X2 respectively, therefore can greatly shorten the length of every drive wire, the quantity of the sensing cell 110 that every drive wire drives has also reduced.Thus, just can reduce the RC load by above-mentioned design, avoid driving the significantly decay of signal.
In addition, although the sensing cell 110 of the every row among the first area I of longitudinal arrangement and the 3rd regional 1II or second area II and the 4th regional IV is from an identical direction Y is upper sensing signal to be read out, but, it also is to read respectively sensing cell 110 in two zoness of different by two different sense wires, therefore the quantity of the sensing cell 110 that reads of every sense wire has also reduced, so can reduce the RC load too, avoid to a certain extent the decay of sensing signal.
One skilled in the art can appreciate that the present invention also can change into other design.For example, can make the cabling of drive wire in the contact panel 100 only pass through a side of contact panel, and the cabling of sense wire pass through respectively the relative both sides of contact panel 100 among the first area I that makes longitudinal arrangement and the 3rd regional III or second area II and the 4th regional IV.In addition, also can make the drive wire among the I of first area pass second area II, and make the drive wire among the 3rd regional III pass the 4th regional IV.In addition, although one skilled in the art can appreciate that contact panel 100 is to be divided into four zones that size is identical in the present embodiment, even if anisotropically being divided into four zones, touch surface 100 can still be suitable for use in technology provided by the present invention.
See also Fig. 4, Fig. 4 is the schematic diagram of a kind of contact panel of disclosing of another embodiment of the present invention.As shown in Figure 4, contact panel 200 is combined by two contact panels 100 that disclose such as Fig. 3, wherein the sense wire in contact panel extracts from a direction Y1, and the sense wire in another piece contact panel extracts from another reverse direction Y2, thereby has consisted of a large-sized contact panel.In other words, contact panel 200 can be a panel, and it is divided into eight zones, and wherein the sense wire in the I-IV zone extracts from direction Y1, and the sense wire in the V-VIII zone extracts from direction Y2, and direction Y1 is opposite with direction Y2.
In addition; those skilled in the art will be understood that; the various elements of contact panel of the present invention can be arranged on the colored filter substrate of liquid crystal display, as are arranged between the protective seam and colored filter of colored filter substrate, so that liquid crystal display has touch controllable function.Perhaps, the various elements of contact panel of the present invention also can be arranged on the independent substrate, thereby consist of a touch-control interface independently.
In sum, the drive wire on the contact panel of the present invention or sense wire pass through respectively the relative both sides of contact panel, and another one is only passed through a side of contact panel, therefore can reduce the RC load, reduce the attenuation amplitude of signal.
Although the present invention discloses as above with preferred embodiment; right its be not to limit the present invention, anyly have the knack of this skill person, without departing from the spirit and scope of the present invention; when can doing a little change and retouching, so protection scope of the present invention is as the criterion when looking the claim person of defining.
