Embodiment
, below in conjunction with accompanying drawing, to the present invention is above-mentioned, with other technical characterictic and advantage, be described in more detail.
See also Figure 1A and Figure 1B, be schematic appearance and the operation chart of preferred embodiment of the present invention.As shown in FIG., contact panel 12 of the present invention is used for electronic installation 1, and electronic installation 1 can be the portable electronic devices such as Smartphone or panel computer, and has outline line 10.Contact panel 12 comprises shielded area 1200 and transparent touch district 1202, and shielded area 1200 is located on the surface of electronic installation 1, and adjacent shielded area, transparent touch district 1,202 1200 arranges, and transparent touch district 1202 major parts by 10 of the outline lines of electronic installation 1 around.As shown in Figure 1B, except shielded area 1200, the user can carry out touch-control on arbitrary position in transparent touch district 1202, above-mentioned position even can be quite near the outline line 10 of electronic installation 1, so electronic installation 1 can obtain effective area and the operations area of maximum.
Fig. 2 is the structural representation of preferred embodiment of the present invention.Apply electronic installation 1 of the present invention and comprise contact panel 12, flat-panel screens 14 and flexible printed wiring board 16.Wherein, contact panel 12 comprises: protective substrate 120, the first induction electrode layer 122 and the second induction electrode layer 123.Wherein, protective substrate 120 has shielded area 1200 and transparent touch district 1202.In the present embodiment, protective substrate 120 can be selected from the made transparent thin boards of arbitrary material such as glass, polycarbonate (PC), polyester (PET), polymethylmethacrylate (PMMA) or cycloolefin co-polymer (COC)., as for the material of shielded area 1200, be that selection is wherein a kind of in the opaque materials such as printing ink, color photoresistance, organic material or inorganic material.
The first induction electrode layer 122 has many first induction electrodes 1221 and many first lead-in wires 1222; wherein said the first induction electrode 1221 is located at the below in the transparent touch district 1202 of protective substrate 120; and described the first lead-in wire end of 1222 is connected respectively described the first induction electrode 1221, and described the first lead-in wire 1222 is located at the below of the shielded area 1200 of protective substrate 120.In addition, the other end of each the first lead-in wire 1222 extends to the first power part 1223, and described the first power part 1223 is positioned at the central part of a lateral margin of the first induction electrode layer 122, in order to flexible printed wiring board 16, to be electrically connected.It should be noted, the first induction electrode 1221 of the present invention is better selects indium tin oxide (Indium Tin Oxide, ITO), and first lead-in wire 1222 is better selects silver-colored line, and its impedance is little and be suitable as the purposes of transmission of signal.
The second induction electrode layer 123 is located at the below of the first induction electrode layer 122; and have many second induction electrodes 1231 and many second lead-in wires 1232; wherein said the second induction electrode 1231 is located on the surface of the second induction electrode floor 123 and is located at the below in the transparent touch district 1202 of protective substrate 120; and described the second lead-in wire 1232 is located on another surface of the second induction electrode layer 123, and an end of described the second lead-in wire 1232 is connected respectively described the second induction electrode 1231.Moreover the other end of each the second lead-in wire 1232 extends to the second power part 1233, and described the second power part 1233 is positioned at two sides of a lateral margin of the second induction electrode layer 123; Therefore, be and be electrically insulated between described the first power part 1223 and described the second power part 1233, and described the second power part 1233 can be electrically connected with flexible printed wiring board 16.It should be noted the better indium tin oxide (Indium Tin Oxide, ITO) of selecting of the second induction electrode 1231 of the present invention.The second lead-in wire material of 1232 is better to be selected wherein a kind ofly in the transparent conductive materials such as Graphene, tin indium oxide, indium zinc oxide or zinc oxide aluminum, be difficult for being found out by naked eyes the existence of the second lead-in wire 1232.In addition, the plain conductor with superfine live width also can be used as the second lead-in wire 1232, has equally and is difficult for the effect of being distinguished by naked eyes.It should be noted that in addition, the flat-panel screens 14 of electronic installation 1 is located at the below in transparent touch district 1202, therefore the image of flat-panel screens 14 can sequentially pass through the second induction electrode floor 123, the first induction electrode floor 122 and transparent touch district 1202, arrives finally user's eyes.
See also Fig. 3 to Fig. 5, be the second induction electrode of preferred embodiment of the present invention and the various cut-open views that are connected of the second lead-in wire.As shown in Figure 3, the second induction electrode layer 123 of the present invention is through special design, it utilizes each second lead-in wire 1232 lateral margin along the second induction electrode layer 123 and extends and be connected to the second corresponding induction electrode 1231, each second induction electrode 1231 and each second power part 1233 that is positioned at the second induction electrode layer 123 bottom surface of the second induction electrode layer 123 end face like this, and form the mode that electrically conducts.In addition, more as shown in Figure 4, the second induction electrode layer 123 has a plurality of perforation 1234, and each second induction electrode 1,231 1234 is connected to corresponding the second lead-in wire 1232 by boring a hole, and then with the second power part 1233, forms and electrically conducts.And for example shown in Figure 5, its embodiment from Fig. 4 is slightly different, and difference is that each second lead-in wire 1232 is 1234 to be connected to the second corresponding induction electrode 1231 by boring a hole.
The second lead-in wire 1232 is located in the bottom surface of the second induction electrode layer 123 in utilization of the present invention, not only can allow the touch-control sensing area of contact panel 12 and viewing area become simultaneously greatly, and can reach again the purpose attractive in appearance of Rimless.
Above explanation is just illustrative for the purpose of the present invention, and nonrestrictive, and those of ordinary skills understand; in the situation that do not break away from the spirit and scope that following claims limit, can make many modifications, change; or equivalence, but all will fall within the scope of protection of the present invention.
