[0091] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0092] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0093] Figure 1 is a schematic diagram of a display panel provided by an embodiment of the present invention, with reference to Figure 1 , including a display area AA; the display panel also includes a touch electrode 10, a gesture recognition electrode 20, a first signal line 30 and a second signal line 40; the touch electrode 10 is connected to the first signal line 30, the gesture recognition electrode 20 is connected to the second signal line 40, the first signal line 30 is used to connect to the touch chip 50, and the second signal line 40 is used to connect to the gesture recognition chip 60; the touch electrode 10 and the gesture recognition electrode 20 are located in the display area AA.

[0094] Specifically, the touch electrode 10 is connected to the touch chip 50 through the first signal line 30. Optionally, part of the touch electrode 10 is used as a touch transmitting electrode, and the other part is used as a touch receiving electrode. When performing touch detection, the user touches the display panel, and the touch chip 50 can output a touch driving signal to the touch transmitting electrode and receive a first sensing signal returned by the touch receiving electrode. The touch chip 50 determines the touch position according to the first sensing signal.

[0095] The display panel further includes a gesture recognition electrode 20, which is connected to a gesture recognition chip 60 via a second signal line 40. In some embodiments, the touch electrode 10 is reused as the gesture recognition electrode 20. In this case, the touch electrode 10 is also connected to the gesture recognition chip 60 via the second signal line 40. In some embodiments, the gesture recognition electrode 20 includes one of a transmitting electrode and a receiving electrode for gesture recognition, and the touch electrode 10 is reused as the other of the transmitting electrode and the receiving electrode for gesture recognition. In other embodiments, the gesture recognition electrode 20 may include a transmitting electrode and a receiving electrode for gesture recognition. Wherein, in the case where the gesture recognition electrode 20 and the touch electrode 10 are independent electrode structures (that is, the gesture recognition electrode 20 is not reused from the touch electrode 10), the gesture recognition electrode 20 is insulated from the touch electrode 10. In this embodiment, an electrostatic field is established by the transmitting electrode and the receiving electrode of gesture recognition, and gesture recognition based on the electrostatic field (i.e., capacitive) is performed, and gesture actions performed in the space are detected based on the change of the electrostatic field distribution by the finger (reflected in the change of capacitance).

[0096] When performing gesture recognition, the user may not touch the display panel. The gesture recognition chip 60 sends a gesture recognition drive signal to the gesture recognition transmitting electrode, receives a second sensing signal from the gesture recognition receiving electrode, and determines the user gesture according to the second sensing signal. The working process of the display panel may include a touch control stage for touch detection and a gesture recognition stage for gesture recognition. Optionally, the touch control stage and the gesture recognition stage are performed in different time periods. There may be a communication connection between the touch chip 50 and the gesture recognition chip 60. In the touch control stage, the touch chip 50 works and the gesture recognition chip 60 does not work; in the gesture recognition stage, the touch chip 50 does not work and the gesture recognition chip 60 works.

[0097] The display panel of this embodiment is provided with a display panel including touch electrodes and gesture recognition electrodes. The touch electrodes are connected to the touch chip through a first signal line, and the gesture recognition electrodes are connected to the gesture recognition chip through a second signal line. In the touch stage, touch detection is realized by the touch chip and the touch electrode. In the gesture recognition stage, gesture recognition is realized by the gesture recognition chip and the gesture recognition electrode. The technical solution of this embodiment performs gesture recognition based on an electrostatic field (i.e., capacitive) by setting gesture recognition electrodes, and detects gesture actions performed in space based on the change of the electrostatic field distribution caused by the finger (reflected in the change of capacitance between the transmitting electrode and the receiving electrode of gesture recognition). Compared with the gesture recognition structure of the prior art, the gesture recognition electrode can have a smaller size to realize integration in the display device. In addition, the gesture recognition electrode and the touch electrode are integrated in the display area, which will not increase the border area of ​​the display panel, and a display panel with a narrow border can be realized.

[0098] Figure 2 is a schematic diagram of the structure of another display panel provided by an embodiment of the present invention, Figure 3 is a partial structural schematic diagram of a display panel provided in an embodiment of the present invention, wherein Figure 3 It is shown in Figure 2 The detailed structure of the touch electrode 10 and the gesture recognition electrode 20 of the display panel is shown in FIG. Figure 2 and Figure 3 Optionally, the touch electrode 10 includes a first touch electrode 11 and a second touch electrode 12, and the gesture recognition electrode 20 includes a first recognition electrode 21, and the first recognition electrode 21, the first touch electrode 11 and the second touch electrode 12 are insulated from each other; the first recognition electrode 21 is configured to form an electric field with at least one of the first touch electrode 11 and the second touch electrode 12 during the gesture recognition stage. Among them, one of the first touch electrode 11 and the second touch electrode 12 is a touch transmitting electrode, and the other is a touch receiving electrode. The first touch electrode 11 and the second touch electrode 12 are respectively connected to the first signal line 30, and the first touch electrode 11 and the second touch electrode 12 are connected to different first signal lines 30.

[0099] Optionally, the first touch electrodes 11 extend along the first direction x, and the plurality of first touch electrodes 11 are arranged along the second direction y; the second touch electrodes 12 extend along the second direction y, and the plurality of second touch electrodes 12 are arranged along the first direction x; the first direction x intersects the second direction y.

[0100] In some optional embodiments of the present invention, the gesture recognition electrode 20 only includes the first recognition electrode 21. In this case, the first touch electrode 11 and / or the second touch electrode 12 are reused as the second recognition electrode. During the gesture recognition stage, the first recognition electrode 21 forms an electric field with at least one of the first touch electrode 11 and the second touch electrode 12 to perform gesture recognition. In this way, the display panel of this embodiment can have fewer gesture recognition electrodes 20 structures added compared to a display panel that does not include a gesture recognition function, thereby simplifying the structure of the display panel. Figure 2 As shown, in another optional embodiment of the present invention, the gesture recognition electrode 20 includes a first recognition electrode 21 and a second recognition electrode 22, and the first recognition electrode is configured to form an electric field with the second recognition electrode during the gesture recognition stage. The first recognition electrode 21 and the second recognition electrode 22 are both structures independent of the touch electrode 10. In this case, it is not necessary to reuse the first touch electrode 11 and the second touch electrode 12 as electrodes for gesture recognition. During the gesture recognition stage, gesture recognition is performed by forming an electric field between the first recognition electrode 21 and the second recognition electrode 22 in the gesture recognition electrode 20. Among them, one of the first recognition electrode 21 and the second recognition electrode 22 is a transmitting electrode for gesture recognition, and the other is a receiving electrode for gesture recognition.
