The information carried in line signal.It is understood that touch chip 141 can also be changed to according to the division of function it is two or more
Chip, also, the first device in other peripheries relevant to touch-control identification and fingerprint recognition can also be integrated in touch-control integrated circuit 140
Part, herein without limitation.
In one embodiment, fingerprint identification area can be set to one or more, also, each fingerprint identification area
4mm should be arranged in area2To 36mm2, it is preferred that the area of a fingerprint identification area is preferably disposed on 9mm2To 25mm2Between.
If the area of a fingerprint identification area is excessive, it is easy for causing interelectrode mutual tolerance in regional area larger, to influence
The touch-control sensitivity of touch panel；If the area of a fingerprint identification area is too small, can not accurately identify more complete
Fingerprint image, to reduce the accuracy of fingerprint recognition.Therefore, the area of fingerprint identification area is arranged in a suitable model
It is very necessary in enclosing.
