Please be with reference to figure 9.Fig. 9 is the synoptic diagram of the touch panel of another embodiment of the present invention, and wherein Fig. 9 demonstrates the top view of the subelement of touch panel.Be that with the embodiment difference of Fig. 7 the touch panel of this enforcement is contact touch panel (a for example resistance-type), therefore less than second thickness corresponding to the second photoresistance separation material 56b, and first thickness still be maximum (also be first thickness greater than second thickness greater than the 3rd thickness) to first substrate 42 corresponding to the 3rd thickness of the 3rd photoresistance separation material 56c.Under this situation, the first spacing h1 of the second photoresistance separation material 56b and first substrate 42 is less than the second spacing h2 of the 3rd photoresistance separation material 56c and first substrate 42 (h2＜h1).When pushing second substrate 44, second substrate 44 can produce deformation makes second conductive layer 58 on the second photoresistance separation material 56b contact with the first conductive pattern 50b, and be as supplemental support in the function of this 3rd photoresistance separation material 56c, excessive and produce excessive deformation or impaired to avoid second substrate 44 or other element because push power.
In various embodiments of the present invention, the first photoresistance separation material 56a, the second photoresistance separation material 56b or the 3rd photoresistance separation material 56c utilize and form with gold-tinted technology, therefore need not increase additional technique can form, and the design difference of its layout visual structure strength demand or sensing element is changed, and is not limited to the mode that the foregoing description discloses.
Please continue with reference to Figure 10, and in the lump referring to figs. 2 to Fig. 8.Figure 10 is the circuit diagram of touch panel one embodiment of the present invention.As shown in figure 10, in touch panel 40, the first conductive pattern 50b in each induction zone 42b and second conductive layer 58 constitute a variable capacitance 70, when an induction zone 42b is pressed, the capacitance variation of variable capacitance 70 promptly can produce signal and be sent to a variable capacitance 70, reaches the effect of touch-control input.Circuit design that what deserves to be explained is touch panel is not limited to this, and can be the circuit design that other is fit to, and for example if touch panel is the embodiment of Fig. 9 is contact, for example resistance-type then should cooperate suitable circuit design.
From the above, touch panel of the present invention has the photoresistance separation material of equal height, but, can under the situation that does not increase any processing step, form touch-control liquid crystal display panel by making first substrate have different thickness (utilizing original each thin layer of change that mask pattern is arranged) at induction zone and non-induction zone.Therefore in addition, touch panel of the present invention is provided with on-off element at each induction zone, and the function of multiple spot input can be provided, and can improve the shortcoming that known touch panel only can the single-point input.
In sum, touch panel of the present invention has the structure of simplification, need not increase any existing technology, only need can form sensing element by the thickness of the existing thin layer of control display panels, therefore not only do not need extra cost, more can increase the homogeneity of sensing element.
The above only is preferred embodiment of the present invention, and all equalizations of doing according to claim of the present invention change and modify, and all should belong to covering scope of the present invention.
