For the ease of understanding the present invention, below with reference to relevant drawings, the present invention is described more fully.In accompanying drawing, provide preferred embodiment of the present invention.But the present invention can realize in many different forms, be not limited to embodiment described herein.On the contrary, providing the object of these embodiment is to make to the understanding of disclosure of the present invention more thoroughly comprehensively.
It should be noted that, term as used herein " vertical ", " level ", " left side ", " right side " and similar statement are just for illustrative purposes.

Refer to Fig. 1, the conducting film 100 of embodiments of the present invention, comprises substrate 110, multiple electrode 120 and multiple lead-in wire electrode 130, and multiple lead-in wire electrodes 130 are for drawing and be transferred to outside by the signal of telecommunication producing on multiple electrodes 120.
Further, transparent substrates can be stiff base, and for example, glass, quartz etc., can be also flexible substrates, for example, and polyethylene terephthalate (PET), polymethyl methacrylate (PMMA), Merlon (PC) etc.Transparent polymeric layer can be UV glue-line, impression glue-line or layer of polycarbonate etc.
Specifically in illustrated embodiment, conducting film 100 requires the transparent conducting film on the product of high transmission rate for being applied to touch control component etc., so electrode 120 be transparency electrode, for example, electrode 120 can adopt the band of the transparent conductive material formation such as ITO to make; Or electrode 120 also can be made for the conductive grid that adopts the opaque materials such as metal to form, because live width, line-spacing and the mesh diameter of grid line is configured to be less than the resolution capability of human eye, so still can guarantee that electrode 120 has transparent visual effect with respect to human eye.Due to the scarcity of indium resource, and Touch Screen series products is to the requirement flexible, conductivity is more and more higher, so in the present embodiment, can adopt Cu, Ag, Ag-C, Al, Ni, Cr and Ni-P one or more alloy material form conductive grid as electrode 120.Can realize like this cost that reduces product, and improve significantly electric conductivity and the pliability of conducting film, simplify Product Process.
It should be noted that, in other embodiments, electrode 120 is not limited to transparency electrode, substrate 110 is not limited to transparent substrates, and electrode 120 can be also non-transparent electrode, and substrate 11 can be also nontransparent substrate, for example, when conducting film 110 is during for the Trackpad of board, notebook computer, touch controlled key plate, electro-magnetic screen layer, electrode 120 can be non-transparent electrode, and substrate 110 can be nontransparent substrate.
Further, electrode 120 can be ribbon, the shape such as latticed.Specifically, in embodiment as shown in Figure 2,3, electrode 120 is the patterned conductive grid being formed by electric conducting material.
Further, if Fig. 2 (a) is to as shown in Fig. 2 (f), the grid pattern of conductive grid can be regular grid pattern, for example, and the grid pattern of the rule such as square, rectangle, parallelogram, rhombus, regular hexagon.If Fig. 2 (g) is to as shown in Fig. 2 (h), the grid pattern of conductive grid can be also irregular random grid figure.
Further, the sideline of the grid pattern of conductive grid can be any one or its combination wherein of straightway, broken line and curved section.
As shown in Figure 3, for specific in the present embodiment, the partial enlarged drawing of the electrode 120 being formed by conductive grid.In the present embodiment, the grid pattern of the conductive grid of electrode 120 is chosen for the irregular random polygon shown in Fig. 2 (g), and this random polygonal sideline is chosen for straightway.In other embodiment, this random polygonal sideline can also be the one in straightway, broken line, curved section, or is wherein multiple combination.In other embodiment, the grid pattern of the conductive grid of electrode 120 can also be chosen for other grid patterns as shown in Fig. 2 (a) to (h), the sideline that surrounds grid pattern can also be the one in straightway, broken line, curved section, or is wherein multiple combination.Because the black matrix" of the colored filter of display device is regular grid graphic array, and superimposed can the generation of the grid pattern of rule have the obviously striped of bright dark difference.So choose on irregular random polygonal mesh figure and display device the grid pattern of rule in the present embodiment when superimposed, can suppress to have the obviously striped of bright dark difference, visual effect is produced obviously and improved.
Further, electrode 120 is unrestricted with respect to the particular location of substrate 110.For example, as shown in Figure 4 (a), in an embodiment, electrode 120 is convexly set at least one surperficial induction zone therein., electrode 120 is formed by the surperficial latticed electric conducting material that is raised in substrate 110.
As shown in Fig. 4 (b) and Fig. 4 (c), in other several embodiment, at least one surperficial induction zone of substrate 110 is provided with the latticed groove being embedded in substrate 110, and electrode 120 is packed in latticed groove., the conductive grid of electrode 120 is formed by the electric conducting material being filled in the surperficial latticed groove that is embedded in substrate 110.Because conductive grid is the groove structure that is embedded in substrate 110 surfaces, so the anti-scratch better effects if of anti-scratch, structure is more stable, and product reliability is higher.
Multiple lead-in wire electrodes 130 are located at least one lip-deep rim area of substrate 110, multiple lead-in wire electrodes 130 are electrically connected with multiple electrodes 120 respectively, the serve as reasons line bunch of the conductive line composition that at least two spaces arrange of each lead-in wire electrode 130, is provided with at least one overlap joint line 140 between every two adjacent conductive lines of line bunch.Because lead-in wire electrode 130 be the line bunch of at least two conductive lines composition, minimumly in line bunch can only include two conductive lines, so the rim area area that the electrode 130 that goes between takies is narrower.And in the application of the conducting films 100 such as flat panel display, photovoltaic device, contact panel and electromagnetic shielding, be the conducting film 100 shared induction zones of top electrode 120 for realizing the effective coverage of corresponding function.Use the lead-in wire electrode 130 of conductive line type, be convenient to manufacture conducting film 100 and the Related product of narrow frame, improve for realizing the induction zone area of corresponding function with respect to the ratio of conducting film 100 entire area, improve the effective rate of utilization of conducting film 100, especially can improve the sensitivity of touch control component, improve the appearance of touch control display apparatus.
In an embodiment, the line bunch of each lead-in wire electrode 130 comprises 2～5 conductive lines therein.Specifically depending on design requirement, conductive line quantity in line bunch is fewer, and the rim area that the electrode that correspondingly goes between need to take is narrower, but electric conductivity is relatively poorer, therefore the quantity of conductive line should not be less than two, otherwise its electric conductivity is difficult to meet the requirement of lead-in wire electrode 130; And conductive line quantity in line bunch is more, correspondingly electric conductivity is better, but the width of rim area is just wider, therefore for making product design attractive in appearance, generally the quantity of conductive line is not more than 5.
Corresponding with electrode 120, multiple lead-in wire electrodes 130 can be arranged on a surface of substrate 110, also can be divided on two groups of two surfaces that are separately positioned on substrate 110.For example, in a lip-deep induction region of substrate 110, be provided with multiple electrodes 120, in rim area, be provided with multiple lead-in wire electrodes 130, each lead-in wire electrode 130 is drawn near the edge of rim area from corresponding electrode 120, is arranged on the same surface of substrate 110.The serve as reasons line bunch of at least two conductive lines composition of each lead-in wire electrode 130, is provided with at least one overlap joint line 140 between every two the adjacent conductive lines in each line bunch.
Further, also guarantee the light transmittance of transparent protective film in order to improve the moulding yield of electrode 120 and lead-in wire electrode 130 simultaneously, the conductive line of the line of the conductive grid of electrode 120, lead-in wire electrode 130 bunch and the live width of overlap joint line 140 are 1 μ m～10 μ m, are highly 2 μ m～6 μ m; And the live width of conductive line and overlap joint line 140 is greater than the grid line live width of conductive grid.Because the live width of conductive line and overlap joint line is thicker, so the impedance of the conductive line of unit length and overlap joint line 140 is less, make the overall antistatic effect of lead-in wire electrode of conductive line type more excellent.
In other embodiment, it is the conductive grid formation of 1 μ m～6 μ m that electrode 120 can also be selected live width.
In other embodiment, it is the conductive grid formation of 1 μ m～5 μ m that electrode 120 can also be selected live width further.
The live width of the conductive grid of electrode 120 is less, and the light transmittance of the induction zone of conducting film 100 is higher, and the image effect in the time that conducting film is applied to touch control display apparatus is better.
Between conductive line due to the line bunch at lead-in wire electrode 130, introduce overlap joint line 140, increase the conductive node in the line bunch of lead-in wire electrode 130, strengthen the electric conductivity of lead-in wire electrode 130, and in the time there is broken string in certain of a certain conductive line in the line bunch of lead-in wire electrode 130, still can guarantee to go between electrode 130 can be by other nodes and line conduction in line bunch, improve electric conductivity and product reliability, improved yield.
Simultaneously, introduce the line bunch of the lead-in wire electrode 130 of overlap joint line 140, conductive node increases in a large number, so in the situation that guaranteeing equal electric conductivity, the conductive line needing still less, the rim area area that lead-in wire electrode 130 takies is narrower, has therefore further reduced rim area width, is convenient to produce the narrower product of frame.
In an embodiment, the overlap joint line 140 between adjacent two conductive lines of lead-in wire electrode 130 can be many therein, and many spacing that overlap between lines 140 are 10～60 μ m.Spacing between overlap joint line 140 is less, and overlap joint line 140 distributes more intensively, and conductive node is more, and the impedance of the electrode 130 that goes between is lower, and electric conductivity is stronger; But correspondingly, because the spacing of overlap joint line 140 becomes close, so the difficulty of manufacturing process also improves, yield is lower.In an embodiment, when the spacing between overlap joint line 140 is got 10 μ m, can reduce to greatest extent the impedance of lead-in wire electrode 130 therein, but corresponding process implementing difficulty is the highest; The spacing overlapping in other embodiment between line 140 is got 60 μ m, and the difficulty of manufacturing process is lower, can obtain higher yield, but the electric conductivity of the electrode 130 that correspondingly goes between is poor.In another embodiment, the spacing of overlap joint between line 140 got 35 μ m, like this, in the line of the electrode 130 that both can guarantee to go between bunch, has enough conductive nodes, guarantees that lead-in wire electrode 130 has good electric conductivity; Meanwhile, also avoid the manufacturing process difficulty of lead-in wire electrode, guaranteed stable product yield.
Further, lead-in wire electrode 130 is unrestricted with respect to the particular location of substrate 110.As shown in Fig. 4 (a) and Fig. 4 (b), therein in an embodiment, the conductive line of line bunch is convexly set at least one surperficial rim area., the conductive line of line bunch is formed by the linear electric conducting material that is raised in substrate 110 surfaces.
As shown in Figure 4 (c), in another embodiment, at least one surperficial rim area of substrate 110 is provided with the linear groove being embedded in substrate 110, and the conductive line of line bunch is packed in linear groove., the conductive line of the line bunch of lead-in wire electrode 130 is formed by the electric conducting material being filled in the linear groove that is embedded in substrate 110 surfaces.Because conductive line is the groove structure that is embedded in substrate 110 surfaces, thus difficult drop-off, the better effects if that anti-scratch is anti-scratch, structure is more stable, and product reliability is higher.
Further, if Fig. 5 (a) is to as shown in Fig. 5 (l), the shape of the conductive line of line bunch is selected from any one or its combination wherein of straightway, broken line and curved section.The shape of at least a portion of the conductive line of line bunch comprises broken line or curved section or its combination.Like this, include the conductive line difficult drop-off more of bending structure, strengthen the anti-scratch effect of anti-scratch; And, serve as reasons when being filled in electric conducting material in the linear groove that is embedded in substrate 110 surfaces and forming when conductive line, for the groove structure that comprises bending, the filling effect of electric conducting material can be better.
Further, overlap joint line 140 is unrestricted with respect to the particular location of substrate 110.For example, as shown in Fig. 4 (a) and Fig. 4 (b), in an embodiment, overlap joint line 140 is for being convexly set in the conductive connecting of at least one surperficial rim area therein., overlap joint line 140 is formed by the linear electric conducting material that is raised in substrate 110 surfaces.
As shown in Figure 4 (c), in another embodiment, at least one surperficial rim area of substrate 110 is provided with the linear groove being embedded in substrate 110, and overlap joint line 140 is for being packed into the conductive connecting in linear groove., by being filled in, electric conducting material in the linear groove that is embedded in substrate 110 surfaces forms overlap joint line 140.Because overlap joint line 140 is for being embedded in the groove structure on substrate 110 surfaces, thus difficult drop-off, the better effects if that anti-scratch is anti-scratch, structure is more stable, and product reliability is higher.
The schematic diagram of axially analysing and observe that Fig. 4 (a) is conducting film 100 to Fig. 4 (c), therefore only symbolically provide in the drawings the line bunch situation about being made up of two conductive lines of lead-in wire electrode 130.Further, if Fig. 5 (d) is to as shown in Fig. 5 (l), in other several embodiment, the line bunch of lead-in wire electrode 130 can also be made up of three conductive lines.In other embodiment, the line bunch of lead-in wire electrode 130 can also be made up of the conductive line of other quantity, such as, in further embodiments, the line bunch of lead-in wire electrode 130 comprises 2～5 conductive lines.
Further, if Fig. 5 (a) is to as shown in Fig. 5 (l), the shape of overlap joint line 140 can be selected from any one or its combination wherein of straightway, broken line and curved section.In certain embodiments, in the middle of overlap joint line 140, the shape of at least a portion comprises broken line or curved section or its combination.Like this, include overlap joint line 140 difficult drop-off more of bending structure, strengthen the anti-scratch effect of anti-scratch; In addition, serve as reasons when being filled in electric conducting material in the linear groove that is embedded in substrate 110 surfaces and forming when overlap joint line 140, for the groove structure that comprises bending, the filling effect of electric conducting material can be better.
Be applied in above-mentioned various embodiment, the electric conducting material of electrode 120, lead-in wire electrode 130 and overlap joint line 140 is any one or several alloy wherein in Cu, Ag, Ag-C, Al, Ni, Cr, Ni-P.
Therein in an embodiment, in the conductive grid of electrode 120, lead-in wire electrode 130 lines bunch and line bunch, overlap the groove of the conductive line of line 140, can be made on a surface of substrate 110 by method for stamping once simultaneously.Then use the mode of blade coating to be filled in the lip-deep groove of substrate 110 conductive ink that contains electric conducting material, last sintering forms the conductive grid, lead-in wire electrode 130 lines bunch of the electrode 120 of electric conducting material composition and the conductive line of overlap joint line 140.Because line bunch and the overlap joint line 140 of electrode 120, lead-in wire electrode 130 are the structure embedding in substrate 110 surfaces, thereby make anti-scratch functional of anti-scratch, the structure of product and performance are comparatively stable.
Because the live width of wall scroll conductive line in lead-in wire electrode 130 lines bunch and the live width of overlap joint line 140 are greater than the live width of the wall scroll grid line of conductive grid, so the recess width of conductive line and overlap joint line 140 correspondences is also greater than the recess width that grid line is corresponding, at filled conductive material in groove time, the filling effect obtaining is better, thereby can produce the product that performance is better.
Further, if Fig. 6 (a) is to as shown in Fig. 6 (c), for conductive grid and the conductive line that the electric conducting material in substrate 110 forms is located in protection, can also on electrode 120 and lead-in wire electrode 130, layer of transparent protective layer 150 be set.Protective clear layer 150 can be formed by transparent polymers such as Merlon, UV glue or impression glue.For being raised in the lip-deep electric conducting material of substrate 110, protective clear layer 150 covers on electric conducting material completely; For the electric conducting material being filled in the groove on substrate 110 surfaces, protective clear layer 150 covers on electric conducting material and the remaining space in groove is filled full.Protective clear layer 150 can be protected product structure further, prevents that electric conducting material is scratched, is shifted.In another embodiment, further, in protective clear layer 150, can also comprise some and have the material of oxidation resistance, suppress electric conducting material oxidized and cause the phenomenon of electric conductivity decline.
Further, as shown in Figure 7, when at least one surperficial rim area is provided with the linear groove being embedded in substrate 110, when the conductive line of line bunch and overlap joint line 140 are packed in linear groove, the width of the cross section of linear groove is W1, and the degree of depth is H1, depth-to-width ratio is H1/W1, and H1/W1 ratio is 0.5～2, for example, the depth-to-width ratio of groove can get 0.5 respectively, 0.8,1,1.2,1.5 and 2.Wherein, in the time that substrate 110 is transparent substrates, the degree of depth of linear groove is less than the thickness of transparent substrates, and in the time that substrate 110 is composite substrate, the degree of depth of linear groove is less than the thickness of the transparent polymeric layer in composite substrate;
Further, as shown in Figure 8, when at least one surperficial induction zone is provided with the latticed groove being embedded in substrate 110, when electrode 120 is packed in latticed groove, the width of the cross section of latticed groove is W2, and the degree of depth is H2, depth-to-width ratio is H2/W2, and the ratio of H2/W2 is 0.5～2, for example, the depth-to-width ratio of groove can get 0.5 respectively, 0.8,1,1.2,1.5 and 2.Wherein, in the time that substrate 110 is transparent substrates, the degree of depth of latticed groove is less than the thickness of transparent substrates; In the time that substrate 110 is composite substrate, the degree of depth of latticed groove is less than the thickness of the transparent polymeric layer in composite substrate.
