In the utility model embodiment, provide a kind of simple in structure, cost is low, cabling is short, to skyLine disturbs little, to be convenient to realize narrow frame fingerprint recognition circuit and electronic equipment.
For achieving the above object, the utility model embodiment provides a kind of fingerprint recognition circuit, bagDraw together: fingerprint identification unit, for identifying fingerprint; Button, is connected with fingerprint identification unit, pressesKey is connected with the control circuit board of electronic equipment by fingerprint identification unit.
As preferably, button is connected with the main control chip of control circuit board by fingerprint identification unit.
As preferably, button comprises function key and return key.
As preferably, function key is positioned at a side of fingerprint identification unit, and return key is positioned at fingerprint to be knownThe opposite side of other unit.
As preferably, function key and return key arrange symmetrically with respect to fingerprint identification unit.
As preferably, button is connected with fingerprint identification unit by a FPC circuit board.
The utility model also provides a kind of electronic equipment, comprises control circuit board and above-mentioned fingerLine identification circuit, the fingerprint identification unit of fingerprint recognition circuit and the control circuit board of electronic equipmentConnect.
As preferably, the control circuit board of electronic equipment comprises main control board and secondary circuit board,The fingerprint identification unit of fingerprint recognition circuit is by the main control chip of secondary circuit board and main control boardConnect.
As preferably, fingerprint identification unit is connected with secondary circuit board by the 2nd FPC circuit board.
As preferably, electronic equipment is mobile phone or panel computer.
The utility model integrates button and fingerprint identification unit, thereby has overcome existing skillIn art, the long problem of connecting line, has not only reduced connecting line length, and has reduced antennaInterference, like this, the connecting line of button no longer need to be mobile through electronic equipment etc. from glass cover-plateThe screen cabling of terminal, thus accomplish that on glass cover-plate, the side by screen need not be walked any lineRoad, thus narrower frame can be accomplished.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, butConduct is not to restriction of the present utility model.
Please refer to Fig. 1, the utility model provides a kind of fingerprint recognition circuit, comprising: fingerprint is knownOther unit 1, for identifying fingerprint; Button, is connected with fingerprint identification unit 1, and button is by referring toLine recognition unit 1 is connected with the control circuit board of electronic equipment. Preferably, button comprises functionKey 3 and return key 4. Preferably, button is by a FPC circuit board 5 and fingerprint recognition listUnit 1 connects. Obviously, also can connect by other forms of connecting line and fingerprint identification unit 1Connect, all belong to equivalents of the present utility model.
Owing to having adopted technique scheme, the button in the utility model can pass through fingerprint recognitionUnit 1 is connected with control circuit board, and the utility model is by integrated to button and fingerprint identification unitGet up, thereby overcome the long problem of connecting line in prior art, not only reduced connecting lineLength, and reduced the interference to antenna, like this, the connecting line of button no longer need to be from glassGlass cover plate is through the screen cabling of the mobile terminals such as electronic equipment, thereby accomplished that button and fingerprint knowCabling is shared in other unit, and on glass cover-plate, the side by screen need not be walked any circuit like this, fromAnd can accomplish narrower frame.
Preferably, described button is by described fingerprint identification unit 1 and described control circuit boardMain control chip connects.
Preferably, function key 3 is positioned at a side of fingerprint identification unit 1, and return key 4 is positioned at fingerThe opposite side of line recognition unit 1. Preferably, function key 3 and return key 4 are known with respect to fingerprintOther unit 1 arranges symmetrically.
The utility model also provides a kind of electronic equipment, comprises control circuit board and above-mentioned fingerLine identification circuit, the fingerprint identification unit 1 of described fingerprint recognition circuit and described electronic equipmentControl circuit board connects.
