First embodiment
Please refer to Fig. 2, it illustrates the top view according to the capacitance type touch-control panel of first embodiment of the invention.Capacitance type touch-control panel 100 comprises a transparency carrier 102, several first metal wires 104, insulation course 106, several second metal wires 108, several first sensing units 110 and several second sensing units 112.Transparency carrier 102 also has substrate surface 114.Wherein, transparency carrier 102 can be the insulativity material of high transmission rate, for example be glass, polycarbonate (Polycarbonate, PC), polyester (Polythyleneterephthalate, PET), polymethylmethacrylate (Polymethylmethacrylate, PMMA) or cycloolefin co-polymer materials such as (Cyclic Olefin Copolymer).
Described first sensing unit 110 and described first metal wire 104 are arranged in many first lines of induction 148, and every first line of induction 148 is arranged along first direction, and first direction herein for example is an X-direction.Described second sensing unit 112 and described second metal wire 108 are arranged in many second lines of induction 150, and every second line of induction 150 is arranged along second direction, and second direction herein for example is a Y direction.
Please be simultaneously with reference to Fig. 2 and Fig. 3, Fig. 3 illustrates the cut-open view of direction 3-3 ' among Fig. 2.First metal wire 104 and first sensing unit 110 are formed on the substrate surface 114.
Please be simultaneously with reference to Fig. 2 and Fig. 4, Fig. 4 illustrates the cut-open view of direction 4-4 ' among Fig. 2.The insulation course 106 and second sensing unit 112 are formed on the substrate surface 114.Second metal wire 108 stride across insulation course 106 electrically connect in described second sensing unit 112 adjacent the two.
Because the material of second metal wire 108 adopts metal, the impedance of metal is lower, can improve the induction sensitivity of capacitance type touch-control panel 100.Wherein, the material of second metal wire 108 no longer repeats to give unnecessary details at this similar in appearance to the material of first metal wire 104.
In addition, because the impedance of metal is lower, so, also can not cause resistance value to surpass the design preset value even the width of the width of first metal wire 104 and second metal wire 108 is made carefullyyer.In addition, very thin first metal wire 104 and the stray capacitance between second metal wire 108 are also very little, can improve the induction sensitivity of capacitance type touch-control panel 100.
In addition, please get back to Fig. 2, capacitance type touch-control panel 100 also comprises several signal wires, for example is several first signal wires 138, several secondary signal lines 140, several the 3rd signal wires 142 and several the 4th signal wires 144.First signal wire 138 electrically connects the part of described first line of induction 148, and secondary signal line 140 electrically connects another part of described first line of induction 148 accordingly, and first signal wire 138 and secondary signal line 140 are interlaced with each other.The 3rd signal wire 142 electrically connects the part of described second line of induction 150 accordingly, and the 4th signal wire 144 electrically connects another part of described second line of induction 150 accordingly, and the 3rd signal wire 142 and the 4th signal wire 144 are interlaced with each other.

The 7th embodiment
Please refer to Figure 23, it illustrates the capacitance type touch-control panel top view according to seventh embodiment of the invention.Continue to use same numeral with the first embodiment something in common among the 7th embodiment, do not repeat them here.Capacitance type touch-control panel 100 differences of the capacitance type touch-control panel 700 of the 7th embodiment and first embodiment are that two ends of the line of induction of capacitance type touch-control panel 700 connect two signal line respectively.
Say that further the described signal wire of capacitance type touch-control panel 700 comprises several the 7th signal wires 756 and several the 8th signal wires 758.The second sensing unit 112a of one end of the first sensing unit 110a of one end of first line of induction 148 that 756 electric connections of the 7th signal wire are corresponding or the second corresponding line of induction 150.The second sensing unit 112b of the other end of the first sensing unit 110b of the other end of first line of induction 148 that 758 electric connections of the 8th signal wire are corresponding or the second corresponding line of induction 150.
In addition, every the 7th signal wire 756 and every the 8th signal wire 758 and be electrically connected to signal output winding displacement (not shown).So, can't when transfer to this signal output winding displacement, one of the 7th signal wire 756 and the 8th signal wire 758 still can transfer to signal by another person of the 7th signal wire 756 and the 8th signal wire 758 and export winding displacement when induced signal.Say further, with first line of induction 148 is example, when the function (for example being broken string) that loses electric connection when first metal wire 104 that connects first sensing unit 110 in first line of induction 148 caused induced signal to be sent to signal output winding displacement by the 7th signal wire 756, then induced signal still can transfer to signal output winding displacement by the 8th signal wire 758.
The disclosed capacitance type touch-control panel of the above embodiment of the present invention has multinomial feature, enumerates Partial Feature and is described as follows:
(1). sensing unit is adjacent setting on the isoplanar, makes that the gap between adjacent sensing unit dwindles.So, except the color uniformity coefficient of the panel surface that increases capacitance type touch-control panel, also can promote the display quality of capacitance type touch-control panel.
(2). the signal wire of capacitance type touch-control panel can have a turnover external form, to promote induction sensitivity.
(3). because signal wire can be formed on two surfaces of differing heights,, make the size of capacitance type touch-control panel therefore become more compact so the required border width of substrate can dwindle.
(4). the material of first metal wire and second metal wire can be a metal.Because the impedance of metal is lower, so even the width of first metal wire and second metal wire is made carefullyyer, also can not cause resistance value to surpass the design preset value.Say that further very thin first metal wire and the stray capacitance between second metal wire are also very little, so help to improve the induction sensitivity of capacitance type touch-control panel.
(5). the sensing unit that is positioned at two ends of every line of induction can be electrically connected to two signal line respectively.Therefore, even when induced signal can't be sent to signal output winding displacement by one of this two signal line person (example is the broken string of the line of induction), still can be sent to signal output winding displacement by another person of this two signal line.
In sum, though the present invention with preferred embodiment openly as above, so it is not in order to limit the present invention.The persond having ordinary knowledge in the technical field of the present invention, without departing from the spirit and scope of the present invention, when being used for a variety of modifications and variations.Therefore, protection scope of the present invention is when looking being as the criterion that claims define.
