Further, in the present invention, the touch display area a is divided into at least two fingerprint sub-areas Aa and a touch sub-area Ab. The distributions of the fingerprint sub-area Aa and the touch sub-area Ab are distinguished in the drawings by broken lines, and it is to be understood that the distributions of the broken lines, the intervals between the broken lines, and the like do not constitute limitations on the distributions of the fingerprint sub-area Aa and the touch sub-area Ab for convenience of description only.

Therefore, the touch panel is provided with the at least two fingerprint sub-areas Aa and the plurality of touch sub-areas Ab, so that the problems that the light-emitting effect is influenced and the design difficulty is increased due to the fact that fingerprint identification can be carried out on the full screen are solved, the light-emitting effect of the touch panel is ensured, and the design difficulty of the touch panel is reduced; and when the touch device needs to perform fingerprint identification, randomly extracting any fingerprint subarea Aa and awakening the fingerprint subarea to be in the fingerprint sensing mode, so that the problems of mistaken opening and mistaken identification caused by accidental touch on a screen are avoided, and the touch device can be unlocked as required.
Specifically, referring to fig. 3, the touch display area a further includes a plurality of fingerprint sensors 11a, and the fingerprint sensors 11a are disposed in the fingerprint sub-area Aa and not disposed in the touch sub-area Ab. Preferably, a plurality of fingerprint sensors 11a are uniformly arranged in each fingerprint sub-area Aa.
Referring to fig. 5a, the sensing control module 33 further includes a fingerprint identification unit 333, and the specific implementation manner of the sensing control module 33 waking up a certain fingerprint sub-region Aa to the touch sensing mode is as follows: the switch unit 331 connects the fingerprint sensor 11a of the fingerprint sub-region Aa to the fingerprint identification unit 333, the fingerprint identification unit 333 sends a fingerprint drive signal to the fingerprint sensor 11a of the fingerprint sub-region Aa, and the fingerprint identification unit 333 receives a fingerprint sensing signal from the fingerprint sensor 11a of the fingerprint sub-region Aa to make the fingerprint sub-region Aa assume the fingerprint sensing mode.
The fingerprint sensor 11a may be provided as any one of a capacitive sensor, a light sensor, an ultrasonic sensor, and the like, and is preferably provided as a capacitive sensor in the present embodiment, which may be further provided as any one of a self-capacitive sensor and a mutual capacitive sensor.

In this embodiment, the third direction is parallel to the first direction, and the fourth direction is parallel to the second direction, but the present invention is not limited thereto in the modified embodiment.
Referring to fig. 5b, when a certain fingerprint sub-region Aa is in the fingerprint sensing mode, the switch unit 331 connects the second driving electrode line Txa and the second sensing electrode line Rxa to the fingerprint identification unit 333, the fingerprint identification unit 333 sends the fingerprint driving signal to the second driving electrode of the fingerprint sensor 11a of the fingerprint sub-region Aa through the second driving electrode line Txa, and the fingerprint identification unit 333 receives the fingerprint sensing signal from the second sensing electrode of the fingerprint sensor 11a of the fingerprint sub-region Aa through the second sensing electrode line Rxa.
Referring to fig. 5a, when a certain fingerprint sub-area Aa assumes the touch sensing mode, the switch unit 331 connects both the first driving electrode line TxA and the first sensing electrode line RxA to the touch recognition unit 332, the touch recognition unit 332 transmits the touch driving signal to the first driving electrode of the touch sensor 11 through the first driving electrode line TxA, and the touch recognition unit 332 receives the touch sensing signal from the first sensing electrode of the touch sensor 11 through the first sensing electrode line RxA, so that the fingerprint sub-area Aa assumes the touch sensing mode, similar to the touch sub-area Ab.
In this embodiment, when a certain fingerprint sub-region Aa is in the touch sensing mode, referring to fig. 5b, the switch unit 331 further connects the second driving electrode lines Txa to the fingerprint recognition unit 333 and floats at least a portion of the second sensing electrode lines Rxa (i.e., disconnects at least a portion of the second sensing electrode lines Rxa from the fingerprint recognition unit 333).
In addition, it can be understood that the fingerprint sensing mode is a case of the non-touch sensing mode, and at this time, that is, when a certain fingerprint sub-area Aa is in the fingerprint sensing mode, referring to fig. 5a, the switch unit 331 further connects the first driving electrode line TxA to the touch recognition unit 332 and floats the first sensing electrode line RxA (that is, disconnects the first sensing electrode line RxA from the touch recognition unit 332).
Further preferably, referring to fig. 3 in combination with fig. 4a to 5b, the distribution density of the touch sensors 11 in the fingerprint sub-area Aa is substantially equal to the distribution density of the touch sensors 11 in the touch sub-area Ab, so that the fingerprint sub-area Aa and the touch sub-area Ab can perform touch sensing with substantially equal resolution, and sensitivity is ensured.
Moreover, the distribution density of the fingerprint sensors 11a in the fingerprint sub-region Aa is much greater than that of the touch sensors 11 in the fingerprint sub-region Aa, that is, the density of the conductive pattern grids in the fingerprint sub-region Aa is greater than that of the conductive pattern grids in the touch sub-region Ab, so that the fingerprint sub-region Aa can meet the requirement of fingerprint sensing.
For example, the resolution range of the fingerprint sensor 11a is not more than 500dpi, wherein dpi (dots Per inc) indicates the number of fingerprint sensors 11a distributed Per inch of length, and dpi reflects the distribution density of the fingerprint sensors 11 a. With this arrangement, it can be ensured that the fingerprint sub-region Aa can perform fingerprint sensing with high precision in the fingerprint sensing mode, and it should be noted that the resolution range of the fingerprint sensor 11a is not limited in this embodiment, as long as it can be ensured that the fingerprint sub-region Aa completes fingerprint sensing in the fingerprint sensing mode.
In addition, it should be noted that, in the present embodiment, the fingerprint sensor 11a and the touch sensor 11 are disposed independently of each other in the fingerprint sub-region Aa, but in the alternative embodiment, this is not limited thereto, for example, some or all of the touch sensors 11 may also be used as the fingerprint sensor 11a to perform fingerprint sensing in the fingerprint sensing mode, that is, some or all of the touch sensors 11 of a certain fingerprint sub-region Aa receive the fingerprint driving signal from the fingerprint identification unit 333 and transmit the fingerprint sensing signal to the fingerprint identification unit 333 in the fingerprint sensing mode.

The randomly extracted fingerprint sub-area Aa can be displayed by lighting the fingerprint sub-area Aa or displaying a preset picture on the fingerprint sub-area Aa so as to identify the position of the fingerprint sub-area Aa. Therefore, the user can conveniently determine the position of the fingerprint input and be reminded to input the fingerprint.
