Figure 1A is the schematic top plan view of the touch-control sensing panel of the utility model first embodiment, and Figure 1B is the diagrammatic cross-section that I-I section along the line is illustrated among Figure 1A.See also Figure 1A and Figure 1B, the touch-control sensing panel 100 of present embodiment comprises a transparency carrier 110, many bridging lines 120 and a sensing patterns layer 130.Transparency carrier 110 has a plane 112, and sensing patterns layer 130 is configured between these bridging lines 120 and the plane 112, and wherein transparency carrier 110 for example is glass plate or transparent plastic plate.
These first sensing array L1 and these second sensing arrays L2 are staggered, wherein 133 bridging lines 120 therein of each bar connecting portion under.Therefore, these connecting portions 133 are staggered with these bridging lines 120 respectively.In addition; Sensing patterns layer 130 can be to be formed by a kind of nesa coating; And this nesa coating for example is indium tin oxide (Indium Tin Oxide; ITO) or indium-zinc oxide (Indium Zinc Oxide, IZO), wherein first sensor pad 131, second sensor pad 132 and connecting portion 133 can be by above-mentioned nesa coating after little shadow (photolithography) and etching (etching) and form.
Each bar bridging line 120 has the bottom surface B1 of a surperficial T1 and an apparent surface T1.Bottom surface B1 and plane 112 are face-to-face, so B1 position, bottom surface is between plane 112 and surperficial T1.Each bar bridging line 120 is single layer structure (single-layer structure); And can be metal material layer; Be that bridging line 120 can be for by the made lead of metal material; The material that wherein constitutes these bridging lines 120 can be reflectivity metal material on the low side and metal nitride or metal oxide, and it can comprise gold, copper, nickel, tungsten or its alloy etc., because these metal materials, metal nitride and metal oxide are black or lead; Has lower reflectivity, so the reflectivity that surperficial T1 had is also lower.Simultaneously, in other embodiments, surperficial T1 also can other black of right and wrong or dimmed material, as long as it can absorb light, avoids reflective, promptly can be applicable in the utility model.
In addition; Touch-control sensing panel 100 can more comprise an insulating trip 140 and a protective seam 150; Wherein insulating trip 140 is arranged between connecting portion 133 and the bridging line 120, and reaching the purpose that is electrically insulated each other, and protective seam 150 covers bridging lines 120 and sensing patterns layers 130.These bridging lines 120 are configurable on insulating trip 140, and cross over insulating trip 140.Because reflectivity that surperficial T1 had is lower, so bridging line 120 is difficult for reflection from the extraneous light that comes, thereby can suppress the generation of bright spot, to reduce the quantity that bright spot occurs.So, can reduce the influence degree of bright spot, and then keep or promote the picture quality of touch control display picture quality.
Fig. 2 is the diagrammatic cross-section of the touch-control sensing panel of the utility model second embodiment.See also Fig. 2, the touch-control sensing panel 200 of second embodiment and the touch-control sensing panel of first embodiment, 100 the two structural similarity.For example, touch-control sensing panel 100,200 all comprises similar elements such as transparency carrier 110, sensing patterns layer 130, insulating trip 140 and protective seam 150.Therefore, mainly introduce touch-control sensing panel 100, the difference between 200 below.As for touch-control sensing panel 100,200 the two identical technical characterictic, then no longer repeat specification and illustrating.
Touch-control sensing panel 100, the difference between 200 are: 200 included many bridging lines 220 of touch-control sensing panel are all sandwich construction, rather than single layer structure.In detail, each bar bridging line 220 is double-decker (double-layer structure), and comprises a conductive layer 222 and an anti-reflecting layer 224, and wherein conductive layer 222 is a single layer structure, and can be metal level, and it for example is aluminum metal layer or molybdenum layer.Anti-reflecting layer 224 is configured on the conductive layer 222, so the surperficial T2 of bridging line 220 is the surface of anti-reflecting layer 224, and the bottom surface B2 of bridging line 220 is the surface of conductive layer 222.
