`strate; a plurality of first conductors; a plurality of second
`conductors cooperating with the first conductors to form a
`matrix of capacitive regions; and a controller connected elec-
`trically to the first and second conductors for detecting the
`capacitance of each of the capacitive regions. Each ofthe first
`conductors is intersected and diVided by the second conduc-
`tors into a series of first electrode sections. Each ofthe second
`conductors is intersected and diVided by the first conductors
`into a series of second electrode sections. Each ofthe first and
`second electrode sections of the first and second conductors
`has a fine conductor line-constructed structure which is con-
`structed from a fine line-shaped conductor.

`
`CAPACITIVE-TYPE TOUCH PANEL
`
`CROSS-REFERENCE TO RELATED
`APPLICATION
`
`[0001] This application claims priority ofTaiwanese Appli-
`cation No. 096123484, filed on Jun. 28, 2007.
`
`BACKGROUND OF THE INVENTION
`
`1. Field of the Invention
`[0002]
`[0003] This invention relates to a capacitive-type touch
`panel, more particularly to a capacitive-type touch panel
`including first and second conductors having sections, each
`having a fine conductor line-constructed structure.
`[0004]
`2. Description of the Related Art
`[0005]
`FIG. 1 illustrates a conventional capacitive-type
`touch panel that includes a transparent substrate 11, a first
`electrode unit 12 formed on a top surface of the transparent
`substrate 11, a second electrode unit 13 formed on a bottom
`surface of the transparent substrate 11, a conductive first
`connecting line unit 15 connected to the first electrode unit
`12, a conductive second connecting line unit 16 connected to
`the second electrode unit 13, and a controller 14 connected to
`the first and second connecting line units 15, 16.
`[0006]
`FIG. 2 illustrates another conventional capacitive-
`type touch panel that includes a transparent substrate 21, a
`first electrode unit 22 formed on a top surface of the transpar-
`ent substrate 21, an insulator layer 24 disposed on the first
`electrode unit 22, and a second electrode unit 23 formed on a
`top surface of the insulator layer 24.
`[0007] When the aforesaid conventional capacitive-type
`touch panels are activated, an electric field distribution is
`generated between the first and second electrode units 12, 13
`(22, 23). At this time, when the user operably touches the
`capacitive-type touch panel at one location, the electric field
`at the location is changed, which results in a change in the
`capacitance between the first and second electrode units 12,
`13 (22, 23) at the location, thereby permitting identification of
`the coordinates of the location through the controller 14.
`[0008]
`Since the first and second electrode units 12, 13 (22,
`23) of the aforesaid conventional capacitive-type touch pan-
`els are made from a transparent conductive material, such as
`indium tin oxide (ITO), which has a much higher sheet resis-
`tance compared to those ofmetals, such as Cu, Ag andAu, the
`sheet resistance of the conventional capacitive-type touch
`panels will be larger than IKQ/square and the capacitance of
`the conventional capacitive-type touch panels from one
`peripheral end to an opposite peripheral end will be larger
`than 400 pF (pico-farad) when the capacitive-type touch
`panel has dimensions larger than 7><7 inches, which can result
`in relatively poor identification of coordinates of a location
`touched by the user, which, in turn, limits production of larger
`sizes of the capacitive-type touch panels.
`
`SUMMARY OF THE INVENTION
`
`[0009] An object of the present invention is to provide a
`capacitive-type touch panel that can overcome the aforesaid
`drawbacks associated with the prior art.
`[0010] According to this invention, there is provided a
`capacitive-type touch panel that comprises: a transparent sub-
`strate; a plurality of first conductors disposed on the transpar-
`ent substrate; a plurality of second conductors disposed on the
`transparent substrate, intersecting insulatively with the first
`conductors, and cooperating with the first conductors to form
`
`a matrix of capacitive regions when a current is applied to the
`first and second conductors; and a controller connected elec-
`trically to the first and second conductors for detecting the
`capacitance of each of the capacitive regions. Each ofthe first
`conductors is intersected and divided by the second conduc-
`tors into a series of first electrode sections. Each ofthe second
`
`conductors is intersected and divided by the first conductors
`into a series of second electrode sections. Each ofthe first and
`second electrode sections of the first and second conductors
`has a fine conductor line-constructed structure which is con-
`
`structed from a fine line-shaped conductor.

`
`according to this invention. The capacitive-type touch panel
`includes: a transparent substrate 3; a plurality of first conduc-
`tors 41 disposed on the transparent substrate 3 and oriented in
`a first direction; a plurality of second conductors 42 disposed
`on the transparent substrate 3, oriented in a second direction
`transverse to the first direction, intersecting insulatively with
`the first conductors 41, and cooperating with the first conduc-
`tors 41 to form a matrix of capacitive regions 4 when a current
`is applied to the first and second conductors 41, 42; and a
`controller 70 connected electrically to the first and second
`conductors 41, 42 through conductive connecting lines 61, 62
`for detecting the capacitance of each ofthe capacitive regions
`4. Each ofthe first conductors 41 is intersected and divided by
`the second conductors 42 into a series of first electrode sec-
`tions 411. Each ofthe second conductors 42 is intersected and
`
`divided by the first conductors 41 into a series of second
`electrode sections 421. Each of the first and second electrode
`sections 411, 421 ofthe first and second conductors 41, 42 has
`a fine conductor line-constructed structure which is con-
`
`structed from a fine line-shaped conductor having a dimen-
`sion that permits the fine line-shaped conductor to be substan-
`tially not visible to the naked eye. Preferably, the fine line-
`shaped conductor has a layer thickness less than 250
`angstroms, and more preferably, ranging from 10-50 ang-
`stroms so as to be transparent, or has a line width less than 200
`microns so as to be substantially not visible to the naked eye.
`Preferably, the fine line- shaped conductor is made from a
`metallic material selected from the group consisting of Cu,
`Al, Au, Ag, Ni, Cr, Mo, and combinations thereof. Formation
`of the first and second conductors 41, 42 can be conducted
`using vapor deposition techniques. It is noted that the fine
`line-shaped conductor can be linear, curved or meandering in
`shape.
`In this embodiment, each of the first and second
`[0030]
`electrode sections 411, 421 ofthe first and second conductors
`41, 42 has a main part 413, 423 (see FIG. 5) that is linear in
`shape, and two opposite bridging parts 417 (427) extending
`from two opposite ends of the main part 413, 423 in opposite
`directions. Each of the bridging parts 417 of each of the first
`electrode sections 411 is connected to and cooperates with an
`adjacent one of the bridging parts 417 of an adjacent one of
`the first electrode sections 411 to define a first bridging line
`415. Each of the bridging parts 427 of each of the second
`electrode sections 421 is connected to and cooperates with an
`adjacent one of the bridging parts 427 of an adjacent one of
`the second electrode sections 421 to define a second bridging
`line 425. The capacitive type touch panel further includes a
`plurality of spaced apart insulators 5, each of which is dis-
`posed at an intersection of the first bridging line 415 inter-
`connecting the main parts 413 of an adjacent pair of the first
`electrode sections 411 and the second bridging line 425 inter-
`connecting the main parts 423 of an adjacent pair of the
`second electrode sections 421, and each of which is sand-
`wiched between the first bridging line 415 interconnecting
`the main parts 413 of the adjacent pair of the first electrode
`sections 411 and the second bridging line 425 interconnecting
`the main parts 423 ofthe adjacent pair ofthe second electrode
`sections 421.
`
`In this embodiment, the transparent substrate 3 has
`[0031]
`opposite first and second surfaces 31, 32, and the first and
`second conductors 41, 42 are formed on the first surface 31 of
`the transparent substrate 3.
`[0032]
`Preferably, the transparent substrate 3 is made from
`a material selected from the group consisting of glass, poly-
`
`polypropylene,
`polyvinylchloride,
`methylmethacrylate,
`polyethylene terephthalate, polyethylene naphthalate, poly-
`carbonate, and combinations thereof.
`[0033]
`Preferably, each of the insulators 5 is made from a
`material selected from the group consisting of photoresist,
`silicon dioxide, titanium dioxide, zinc oxide, silicon nitride,
`aluminum nitride, tantalum oxide, and combinations thereof.
`[0034]
`FIG. 6 illustrates the second preferred embodiment
`ofthe capacitive-type touch panel according to this invention.
`The second preferred embodiment differs from the previous
`embodiment in that the main part 413, 423 of the fine con-
`ductor line-constructed structure of each of the first and sec-
`ond electrode sections 411, 421 of the first and second con-
`ductors 41, 42 includes a linear stem portion 4131, 4231 and
`spaced apart linear branch portions 4132, 4232 transverse to
`the linear stem portion 4131, 4231.
`[0035]
`FIGS. 7 and 8 illustrate the third preferred embodi-
`ment of the capacitive-type touch panel according to this
`invention. The third preferred embodiment differs from the

`73 disposed on the second surface 32 of the transparent sub-
`strate 3 (in this embodiment, it is formed directly on the
`second surface 32 of the transparent substrate 3) and func-
`tioned as one of a grounding medium and an electromagneti-
`cally shielding medium. The conductive layer 73 is preferably
`made from a transparent conductive material. The screen-like
`structure permits enhancement in reduction ofthe sheet resis-
`tance of the capacitive-type touch panel. The protective layer
`71 is preferably made from a material selected from the group
`consisting of adhesive, resin, photoresist, oxides, nitrides,
`and combinations thereof.
