Embodiment
Below with reference to drawing, detailed annotation embodiments of the invention:
Characteristic on above-mentioned purpose of the present invention and structure and fuction thereof, is explained the preferred embodiment according to institute's accompanying drawing.
Refer to Fig. 1,2,3, for the three-dimensional exploded view of contact panel first embodiment of tool finger print identification function of the present invention and the decomposition of non-visible area are analysed and observe and assembled sectional view, as shown in the figure, the contact panel of tool finger print identification function of the present invention, comprising: glass substrate 1, fingeprint distinguisher 2, encapsulated layer 3, optical cement layer 4, confining bed 5;
Described glass substrate 1 has visible area 11 and non-visible area 12 and one first plane 13 and one second plane 14, and at least one groove portion 121 is offered in the non-visible area 12 of described second plane 14, and described groove portion 121 has a bottom side 1211.
Described visible area 11 has one first electrode layer 111 and insulation course 112 and routing layer 113 and a second electrode lay 114, and first and second electrode layer 111,114 described and this routing layer 113 are electrically connected.
Described fingeprint distinguisher 2 is arranged in described groove portion 121, this fingeprint distinguisher 2 has a substrate 21, described substrate 21 has one first side 211, this first side 211 is provided with a silicon substrate 22, described silicon substrate 22 and this substrate 21 are by least one wire 23 electrically connect, the opposite side of described silicon substrate 22 this substrate 21 contrary is then provided with multiple identification of fingerprint chip 24, and these identification of fingerprint chips 24 have induction zone 241 and an end face 242, and wherein this induction zone 241 is formed at this end face 242.
First side 211 of the coated described wire 23 of described encapsulated layer 3 and described substrate 21 and this silicon substrate 22 side exposed section.
This optical cement layer 4 is located between this fingeprint distinguisher 2 and the bottom side 1211 in this groove portion 121; Described fingeprint distinguisher 2 is closed in the groove portion 121 of described glass substrate 1 by described confining bed 5.
