Embodiment
Fig. 2 A and Fig. 2 B are respectively the upward view and the vertical view of the contact panel of one embodiment of the invention.Please be simultaneously with reference to Fig. 2 A and Fig. 2 B, contact panel 200 has a sensing area 202 and a surrounding zone 204, and surrounding zone 204 is around sensing area 202.Contact panel 200 comprises a substrate 210, a decorative pattern 220, a light shield layer 230 and a touch control component 240, and wherein touch control component 240 comprises at least one sensing electrode 242 and at least one transfer wire 244.In the present embodiment, decorative pattern 220 and light shield layer 230 all are arranged in surrounding zone 204.244 of sensing electrode 242 and transfer wires are positioned at sensing area 202 and surrounding zone 204 respectively, and transfer wire 244 electrically connects sensing electrode 242.
Though showing among the figure has a plurality of sensing electrodes 242 and many transfer wires 244, but in other embodiment, single sensing electrode 242 or single transfer wire 244 also can constitute the touch control component 240 of contact panel 200.That is to say that the quantity of sensing electrode 242 and transfer wire 244 is not restricted to single or a plurality of.And; The shape of sensing electrode 242 is not an example with the state shown in scheming also; In other embodiments, sensing electrode 242 can be that whole face is formed at the electrode layer in the sensing area 202, also can be by a plurality of rhombuses, rectangle, the formed electrode serial of polygonal electrode.Certainly, sensing electrode 242 also can be the strip shaped electric poles that is formed at sensing area 202.
In addition, the light shield layer 230 shown in the present embodiment is a continuous shaped as frame, and it fills up whole surrounding zone 204 haply to constitute frame pattern.But, in other embodiments, light shield layer 230 can only be formed on the local area of surrounding zone 204 with the pattern that constitutes a strip, the pattern of L type.What deserves to be mentioned is that light shield layer 230 is continuous in surrounding zone 204, particularly, the part light shield layer 230 that disposes transfer wire 244 does not have any opening or slit or gap etc.
The state that direct viewing was painted to Fig. 2 B when particularly, the user used contact panel 200.That is to say, can see the light shield layer 230 and the decorative pattern 220 that are arranged in surrounding zone 204 when the user uses contact panel 200, wherein decorative pattern 220 can demonstrate article card mark (logo), button diagram (Icon) or any required figure.
In the present embodiment, light shield layer 230 is lighttight rete.And decorative pattern 220 can be covered and can't be in sight by light shield layer 230 in upward view (being Fig. 2 A), and the transfer wire 244 of touch control component 240 is understood in vertical view (being Fig. 2 B) by light shield layer 230 and covered and can't be in sight.Also promptly, the transfer wire 244 in decorative pattern 220 and the touch control component 240 lays respectively at light shield layer 230 relative both sides.So, are direct viewings when the user uses contact panel 200 to the state of Fig. 2 B and can not see transfer wire 244.In addition, the transfer wire 244 of present embodiment can directly be disposed on the light shield layer 230 and not receive the influence of decorative pattern 220, uses to have preferable reliability.
In detail, Fig. 2 C is wherein contact panel 200 partial cutaway schematic that transfer wire is drawn of edge.Please with reference to Fig. 2 C, substrate 210 has a component side 212 and a touching face 214 in fact, and component side 212 and touching face 214 are against each other.Touching face 214 comes down to the surface that user use contact panel 200 time institute watches and touches.In the present embodiment, decorative pattern 220 is disposed on the touching face 214, and the transfer wire 244 of light shield layer 230 and touch control component 240 all is disposed on the component side 212.In addition, contact panel 200 also comprises a protective film 250, and it is disposed on the touching face 214 to cover decorative pattern 220.In one embodiment, protective film 250 is a transparent membrane or an optical thin film etc.
The decorative pattern 220 of present embodiment is disposed on the touching face 214 of substrate 210, so light shield layer 230 has not been required to be the opening that exposes decorative pattern 220 and be formed with given shape.So, on processing procedure, need not use extra light shield on light shield layer 230, to form opening corresponding to decorative pattern 220.Therefore, decorative pattern 220 is disposed on the touching face 214 of substrate 210 and helps to reduce cost of manufacture.
In addition, in contact panel 200, light shield layer 230 is disposed at not homonymy respectively with decorative pattern 220, and can not stack together.Therefore, light shield layer 230 has a flat surfaces 232 away from a side of substrate 210.Thus, transfer wire 244 is configurable on flat surfaces 232, so transfer wire 244 is not easy to take place to break or the inconsistent phenomenon of impedance because of the uneven thickness of bottom film layer.That is to say that the flat surfaces 232 that light shield layer 230 is provided helps to improve the reliability of transfer wire 244.Therefore, contact panel 200 can have good quality.
In one embodiment, decorative pattern 220 can directly be made on the touching face 214 of substrate 210 by modes such as printing process, coating process.In addition, decorative pattern 220 also can be formed at earlier on the protective film 250, by the step that protective film 250 is attached on the substrate 210 decorative pattern 220 is disposed on the touching face 214 of substrate 210 again.According to the design of present embodiment, the configuration of decorative pattern 220 does not influence the making step and the design of other elements on the component side 212 (like touch control component 240, light shield layer 230 etc.).Therefore, no matter why are other circuit elements design or specification, and decorative pattern 220 can be applied in the contact panel 200.No matter that is to say, be any type of contact panels 200 such as resistance-type, condenser type, multipoint mode, single-point type, need not change existing production method and make tool, can have the decorative pattern 220 of present embodiment.
In sum, the decorative pattern used of contact panel of the present invention light shield layer that shading is used and display pattern mark is disposed at the relative both sides of a substrate respectively.So light shield layer need not have the opening corresponding to decorative pattern, and has smooth surface.Thus, when being disposed at the transfer wire in the touch control component on the light shield layer, transfer wire is not easy broken string or the uneven situation of impedance.In addition, the fabricator does not need on light shield layer, to form opening with customized tool (like light shield), only need can accomplish decorative pattern 220 through the comparatively cheap means of cost (like printing process).So contact panel of the present invention can have good element reliability and a kind of design of low cost of manufacture also is provided.
Though the present invention discloses as above with embodiment, so it is not in order to limiting the present invention, any under those of ordinary skill in the technical field, when can doing a little change and retouching, and do not break away from the spirit and scope of the present invention.
