In an embodiment, referring to fig. 1 and fig. 2, fig. 1 illustrates a schematic structural diagram of a touch panel in the present embodiment; fig. 2 is a schematic circuit diagram of a touch film layer on a touch panel according to the present embodiment. As shown in fig. 1 and 2, the touch panel 100 includes a touch film layer 110, and a fingerprint identification area 120 and a non-fingerprint identification area distributed on the touch film layer 110, wherein the non-fingerprint identification area refers to an area other than the fingerprint identification area 120. Specifically, the fingerprint identification area 120 and the non-fingerprint identification area on the touch film layer 110 are both provided with a plurality of criss-cross touch driving electrodes 112 and a plurality of touch sensing electrodes 114, wherein the touch driving electrodes 112 and the touch sensing electrodes 114 arranged in the fingerprint identification area 120 are more dense than the electrodes arranged in the non-fingerprint identification area, and correspondingly, the grid density formed by the intersection of the touch driving electrodes 112 and the touch sensing electrodes 114 in the fingerprint identification area 120 is also higher. It should be noted that the positions of the touch driving electrode 112 and the touch sensing electrode 114 can be interchanged, and the touch driving electrode 112 and the touch sensing electrode 114 can be made of ITO (Indium Tin Oxide) thin film.
Further, as shown in fig. 2, the touch driving electrode 112 and the touch sensing electrode 114 in the fingerprint identification area 120 may be electrically connected to the fingerprint sensing element 143 and the touch sensing element 144 through the signal connection line 132 and the switch 142, respectively, so as to sense the touch signal and the fingerprint signal in different modes, respectively.

In one embodiment, as shown in fig. 2, the touch driving electrodes 112 and the touch sensing electrodes 114 in the fingerprint identification area 120 respectively extend from four directions to the non-fingerprint identification area, and the touch driving electrodes 112 and the touch sensing electrodes 114 in the fingerprint identification area 120 share the same set of signal connection lines and the touch sensing elements 144 with the portions thereof extending to the non-fingerprint identification area. It should be noted that the portion of the fingerprint identification area 120 where the touch driving electrodes 112 and the touch sensing electrodes 114 extend to the non-fingerprint identification area is also used as touch electrodes, and does not affect the touch identification function of the extended area. Specifically, in the touch mode, all touch driving electrodes 112 and all touch sensing electrodes 114 on the touch panel operate simultaneously, and sense touch signals generated at all positions on the touch panel; in the fingerprint identification mode, only the touch driving electrodes 112 and the touch sensing electrodes 114 in the fingerprint identification area operate, and only the fingerprint signal in the fingerprint identification area is sensed, so that the simpler the switching mode between the two modes is, the faster the response speed of the touch panel is. In this embodiment, the touch electrodes in the fingerprint identification area and the touch electrodes extending to the non-fingerprint identification area share the same signal connection line and the same touch sensing element, so that other settings for the circuit are not needed, and the conversion between the two modes can be realized only by inputting the conversion signal to the conversion switch 142 through the touch chip 141, and the conversion process is very convenient and fast.
In one embodiment, as shown in fig. 2, the signal connection lines include a signal input line 131 and a signal output line 132. Specifically, in the touch mode, the transfer switch is connected to the touch sensing element 144, the driving chip 141 sends a touch driving signal to the touch driving electrode 112 through the signal input line 131, the change of the sensing capacitance sensing signal generated at the electrode overlapping position, and then the collected touch signal is sent back to the touch sensing element 144 and the touch chip 141 through the touch sensing electrode 114 and the signal output line 132, so as to identify accurate touch information; in the fingerprint recognition mode, the change-over switch is connected with the fingerprint sensing element 143, the driving chip 141 sends a fingerprint driving signal to the touch driving electrode 112 in the fingerprint recognition area through the signal input line 131, the change of the sensing capacitance sensing signal generated at the electrode overlapping position is further sent to the fingerprint sensing element 143 and the touch chip 141 through the touch sensing electrode 114 and the signal output line 132, and therefore accurate fingerprint information is recognized.

In the present embodiment, the touch chip 141 is the most important component of the touch integrated circuit 140, and can be used for transmitting a touch driving signal, transmitting a fingerprint driving signal, receiving a touch signal, receiving a fingerprint signal, and analyzing information carried in the touch signal and the fingerprint signal. It is understood that the touch chip 141 may be changed to two or more chips according to the functional division, and other peripheral components related to touch recognition and fingerprint recognition may also be integrated in the touch integrated circuit 140, which is not limited herein.
In one embodiment, the fingerprint identification area can be set to be one or more, and the area of each fingerprint identification area should be set to be 4mm 2 To 36mm 2 Preferably, an area of the fingerprint identification area is set to be 9mm 2 To 25mm 2 In the meantime. If the area of a fingerprint identification area is too large, the mutual capacitance between electrodes in a local area is easy to be larger, so thatThe touch sensitivity of the touch panel is influenced; if the area of one fingerprint identification area is too small, a complete fingerprint image cannot be accurately identified, so that the accuracy of fingerprint identification is reduced. Therefore, it is necessary to set the area of the fingerprint identification section within a suitable range.
An embodiment of the present invention further provides a touch display device, including: the touch display panel according to any one of the above embodiments. Specifically, the touch display device can be any product or component with a display function, such as a mobile phone, a tablet personal computer, a television, a display, a notebook computer, a digital photo frame, a navigator, an intelligent wearable device, and the like. The touch display device integrates three functions of display, touch control and fingerprint identification on the same display panel, so that the display device is more intelligent. Other essential components of the display device are all understood by those skilled in the art, and are not described herein.
In one embodiment, as shown in fig. 3, the present application further provides a driving control method of a touch panel, which can be applied in the touch chip 141 shown in fig. 2, and the method includes the following steps:
step S102: whether the touch panel generates operation meeting preset conditions is detected.
The operation of the preset condition refers to an operation that can start a fingerprint identification mode, for example, the operation of the preset condition may be to open an application program that needs to perform fingerprint identification, start fingerprint authentication unlocking, perform fingerprint payment, or the like.

In this embodiment, there may be a plurality of fingerprint identification areas, but all the fingerprint identification areas are not necessarily displayed, and when fingerprint verification is performed, only the same number of fingerprint identification areas as the number of fingerprints to be verified need to be displayed. For example, when single fingerprint verification is performed, only one fingerprint identification area is displayed on the touch panel; when double fingerprint verification is performed, two fingerprint identification areas are displayed on the touch panel, as shown in fig. 5.
Step S204: and determining the display position of the fingerprint identification area to be displayed according to the number of the fingerprint identification areas to be displayed.
