Compared with prior art, the present embodiment has the advantages that by making the touch panel have at least two
A fingerprint subregion Aa and multiple touch subregion Ab, avoid it is full frame can influence illumination effect caused by fingerprint recognition and
The problem of increasing design difficulty, ensure that the illumination effect of the touch panel, reduces the design difficulty of the touch panel；
Also, when the touch device needs to carry out fingerprint recognition, randomly selects any fingerprint subregion Aa and wake up in the finger
Line sensing modes open, misidentify to avoid the problem that opening by mistake caused by touching screen because of accident, guaranteeing the touch device
It can unlock on demand.
