Detailed Implementation

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0020] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0021] Figure 1 This is a schematic diagram of the structure of a display panel provided in an embodiment of the present invention, for reference. Figure 1 The display panel includes 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.

[0022] Specifically, the touch electrode 10 is connected to the touch chip 50 via the first signal line 30. Optionally, a portion of the touch electrode 10 serves as a touch transmitting electrode, and another portion serves as a touch receiving electrode. During touch detection, when a user touches the display panel, 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 then determines the touch position based on the first sensing signal.

[0023] The display panel also includes a gesture recognition electrode 20, which is connected to the 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 and receiving electrodes for gesture recognition. In other embodiments, the gesture recognition electrode 20 may include both a transmitting electrode and a receiving electrode for gesture recognition. Wherein, when the gesture recognition electrode 20 and the touch electrode 10 are independent electrode structures (i.e., 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 through the transmitting and receiving electrodes for gesture recognition, and gesture recognition based on the electrostatic field (i.e., capacitive) is performed. The gesture action performed in space is detected based on the change in the distribution of the electrostatic field by the finger (reflected in the change in capacitance).

[0024] During gesture recognition, the user does not need to contact the display panel. The gesture recognition chip 60 sends a gesture recognition drive signal to the gesture recognition transmitting electrode and receives a second sensing signal from the gesture recognition receiving electrode, determining the user's gesture based on the second sensing signal. The operation of the display panel can include a touch detection phase and a gesture recognition phase; optionally, the touch detection phase and the gesture recognition phase are performed time-sharingly. A communication connection can exist between the touch chip 50 and the gesture recognition chip 60. During the touch detection phase, the touch chip 50 is active, and the gesture recognition chip 60 is inactive; during the gesture recognition phase, the touch chip 50 is inactive, and the gesture recognition chip 60 is active.

[0025] The display panel of this embodiment includes touch electrodes and gesture recognition electrodes. The touch electrodes are connected to a touch chip via a first signal line, and the gesture recognition electrodes are connected to a gesture recognition chip via a second signal line. During the touch phase, touch detection is achieved through the touch chip and touch electrodes; during the gesture recognition phase, gesture recognition is achieved through the gesture recognition chip and gesture recognition electrodes. This embodiment's technical solution, by setting gesture recognition electrodes, performs electrostatic field-based (i.e., capacitive) gesture recognition. It detects gesture actions performed in space based on changes in the electrostatic field distribution caused by the finger (reflected in changes in capacitance between the transmitting and receiving electrodes of the gesture recognition device). Compared to existing gesture recognition structures, the gesture recognition electrodes can have a smaller size, enabling integration into the display device. Furthermore, integrating the gesture recognition electrodes and touch electrodes into the display area does not increase the bezel area of ​​the display panel, allowing for a narrow-bezel display panel.

[0026] Figure 2 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention. Figure 3 This is a partial structural diagram of the display panel provided in an embodiment of the present invention, wherein... Figure 3 It shows Figure 2 The detailed structure of the touch electrode 10 and gesture recognition electrode 20 of the display panel shown is referenced. 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. 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 phase. 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 a first signal line 30, and the first signal lines 30 connected to the first touch electrode 11 and the second touch electrode 12 are different.

[0027] Optionally, the first touch electrode 11 extends along the first direction x, and a plurality of first touch electrodes 11 are arranged along the second direction y; the second touch electrode 12 extends along the second direction y, and a plurality of second touch electrodes 12 are arranged along the first direction x; the first direction x and the second direction y intersect.

[0028] In some optional embodiments of the present invention, the gesture recognition electrode 20 includes only 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. Thus, the display panel of this embodiment has fewer additional gesture recognition electrodes 20 compared to a display panel without gesture recognition functionality, 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. The first recognition electrode is configured to form an electric field with the second recognition electrode during the gesture recognition phase. Both the first recognition electrode 21 and the second recognition electrode 22 are independent structures from 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 gesture recognition electrodes. During the gesture recognition phase, 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. One of the first recognition electrode 21 and the second recognition electrode 22 serves as the transmitting electrode for gesture recognition, and the other as the receiving electrode for gesture recognition.

[0029] Figure 4 This is a cross-sectional view of a display panel provided in an embodiment of the present invention. Figure 4 Can correspond Figure 3 As shown in the BB' section, in some embodiments, the display panel includes at least two conductive layers, with the touch electrodes and gesture recognition electrodes located on the same conductive layer. This configuration prevents the addition of additional film layers to the display panel due to the gesture recognition electrodes, thereby eliminating the need for additional patterning steps, simplifying the display panel manufacturing process, reducing manufacturing costs, and ensuring a relatively thin and lightweight display panel.

[0030] In some embodiments, the display panel includes a substrate 100 and a first conductive layer 200 and a second conductive layer 300 stacked on the substrate 100. Optionally, touch electrodes are located in the first conductive layer 200 and the second conductive layer 300, and gesture recognition electrodes are located in the first conductive layer 200 and / or the second conductive layer 300.

[0031] In some embodiments, the first touch electrode 11 is located in the first conductive layer 200, and the second touch electrode 12 is located in the second conductive layer 300. In other embodiments, one of the first touch electrode 11 and the second touch electrode 12 is located in the first conductive layer 200, and a portion of the other is located in the first conductive layer 200, while another portion is located in the second conductive layer 300; or, one of the first touch electrode 11 and the second touch electrode 12 is located in the second conductive layer 300, and a portion of the other is located in the first conductive layer 200, while another portion is located in the second conductive layer 300. The gesture recognition electrode 20 is located in at least one of the conductive layers, the first conductive layer 200 and the second conductive layer 300. Figure 4 An example is shown where the second touch electrode is located in the second conductive layer 300, and a portion of the structure of the first touch electrode is located in the first conductive layer 200, while a portion of the structure is located in the second conductive layer 300. The gesture recognition electrode 20 is located in both the first and second conductive layers 200 and 300.

[0032] Optionally, the first signal line is located in either the first conductive layer or the second conductive layer, and the second signal line is located in both the first and second conductive layers. This allows the first and second signal lines to be fabricated simultaneously with the first and second touch electrodes, further simplifying the display panel fabrication process.

[0033] The first conductive layer 200 comprises at least one material selected from metal, alloy, or metal compound, optionally Ti / Al / Ti, with a film thickness of 100-600 nm. The second conductive layer 300 comprises at least one material selected from metal, alloy, or metal compound, optionally Ti / Al / Ti, with a film thickness of 100-600 nm. An insulating layer is disposed between the first conductive layer 200 and the second conductive layer 300. The insulating layer comprises at least one material selected from SiNx, SiOx, and SiOxNy, optionally SiNx, with a film thickness of 100-400 nm.

[0034] Continue to refer to Figures 2-4 Optionally, the touch electrode 10 includes a plurality of first sub-electrode blocks 101, and the gesture recognition electrode 20 includes a plurality of second sub-electrode blocks 201; the first sub-electrode blocks 101 and the second sub-electrode blocks 201 are insulated from each other.

[0035] Optionally, the first sub-electrode block 101 and the second sub-electrode block 201 are located in the first conductive layer 200 or the second conductive layer 300. Figure 4 The example illustrates the case where the first sub-electrode block 101 and the second sub-electrode block 201 are located in the second conductive layer 300.

[0036] In some embodiments, the first touch electrode 11 includes a plurality of interconnected first sub-electrode blocks 101, and the second touch electrode 12 includes a plurality of interconnected first sub-electrode blocks 101; the first sub-electrode blocks 101 included in the first touch electrode 11 and the second touch electrode 12 are different, and the first sub-electrode blocks 101 included in the first touch electrode 11 and the second touch electrode 12 are insulated from each other. Optionally, the first touch electrode 11 further includes a first connecting line L1, in which adjacent first sub-electrode blocks 101 are connected by the first connecting line L1; the second touch electrode 12 further includes a second connecting line L2, in which adjacent second sub-electrode blocks 201 are connected by the second connecting line L2. In some embodiments, the first connecting line L1 and the second connecting line L2 are located in different conductive layers in the display panel; in some embodiments, one of the first connecting line L1 and the second connecting line L2 is located in the first conductive layer 200, and the other is located in the second conductive layer 300. The display panel also includes a substrate 100, and the orthographic projection of the first connecting line L1 on the substrate 100 overlaps with the orthographic projection of the second connecting line L2 on the substrate 100. By setting the first connecting line L1 and the second connecting line L2 to be located in different conductive layers, short circuits between the first touch electrode 11 and the second touch electrode 12 are avoided, ensuring the reliability of touch detection.

[0037] Optionally, if one of the first touch electrode 11 and the second touch electrode 12 is located in the first conductive layer 200 and the other is located in the second conductive layer 300, the first sub-electrode block 101 and the first connecting line L1 included in the first touch electrode 11 are located in one of the first conductive layer 200 and the second conductive layer 300, and the first sub-electrode block 101 and the second connecting line L2 included in the second touch electrode 12 are located in the other of the first conductive layer 200 and the second conductive layer 300.

[0038] In some embodiments, the first sub-electrode block 101 included in the first touch electrode 11 and the first sub-electrode block 101 included in the second touch electrode 12 are both located in one of the first conductive layer 200 or the second conductive layer 300. The first connecting line L1 may be located in the first conductive layer 200, and the second connecting line L2 may be located in the second conductive layer 300; or the first connecting line L1 may be located in the second conductive layer 300, and the second connecting line L2 may be located in the first conductive layer 200. Figure 3 and Figure 4An exemplary illustration shows a scenario where the first sub-electrode block 101 of the first touch electrode 11 and the first sub-electrode block 101 of the second touch electrode 12 are both located on the second conductive layer 300, the first connecting line L1 is located on the first conductive layer 200, and the second connecting line L2 is located on the second conductive layer 300. Thus, in the first touch electrode 11 and the second touch electrode 12, adjacent first sub-electrode blocks 101 of one are connected by connecting lines on the same layer, while adjacent first sub-electrode blocks 101 of the other are connected by bridge connecting lines on different layers. It should be noted that in this embodiment of the invention, the vertical relationship between the first conductive layer 200 and the second conductive layer 300 is not limited; the first conductive layer 200 can be located between the second conductive layer 300 and the substrate 100, and the first conductive layer 200 can be located on the side of the second conductive layer 300 away from the substrate 100.

Figures 2-5 In some embodiments, the first recognition electrode 21 includes a plurality of interconnected second sub-electrode blocks 201; the first recognition electrode 21 is configured to form an electric field with at least one of at least a portion of the second sub-electrode blocks 201 outside the first recognition electrode 21 during the gesture recognition phase. The at least a portion of the second sub-electrode blocks 201 outside the first recognition electrode 21 serve as the second recognition electrode 22 for gesture recognition.

[0040] Optionally, the first identification electrode 21 further includes a third connecting line L3, which is located in the first conductive layer 200 or the second conductive layer 300. Figure 3 and Figure 5 An exemplary illustration shows the case where the third connecting line L3 is located in the first conductive layer 200. In the first identification electrode 21, at least a portion of adjacent second sub-electrode blocks 201 are connected via the third connecting line L3. In some embodiments, the third connecting line L3 is located in the same layer as the first connecting line L1 and is insulated from it; optionally, the first connecting line L1 is parallel to the third connecting line L3. In other embodiments, the third connecting line L3 is in the same layer as the second connecting line L2 and is insulated from it; optionally, the third connecting line L3 is parallel to the second connecting line L2.

[0041] In some embodiments, the first sub-electrode block 101 and the second sub-electrode block 201 are arranged in a one-to-one correspondence, that is, the number of first sub-electrode blocks 101 in the display panel is equal to the number of second sub-electrode blocks 201. In other optional embodiments of the present invention, the number of first sub-electrode blocks 101 may be more or less than the number of second sub-electrode blocks 201.

[0042] Optionally, the first sub-electrode block 101 and the corresponding second sub-electrode block 201 are insulated in the same layer; this allows the gesture recognition electrode 20 and the touch electrode 10 to be formed in the same conductive layer, so that the gesture recognition electrode 20 does not need to be added to the display panel with an additional film layer structure, simplifying the manufacturing process of the display panel and ensuring that the display panel is relatively thin.

[0043] In some embodiments, the first sub-electrode block 101 and the second sub-electrode block 201 are fabricated simultaneously and made of the same material, thereby further simplifying the fabrication process of the display panel. For example, after forming the conductive layer, the first sub-electrode block 101 and the second sub-electrode block 201 can be formed simultaneously by patterning the conductive layer.

[0044] Optionally, the first sub-electrode block 101 is located around the second sub-electrode block 201.

[0045] Specifically, the display panel may include a substrate 100, and the orthographic projection of the first sub-electrode block 101 on the substrate 100 surrounds the orthographic projection of the second sub-electrode block 201 on the substrate 100. Figure 6 This is the structure of the electrode block in the display panel provided in the embodiment of the present invention, with reference to... Figure 6 In another optional embodiment of the present invention, the first sub-electrode block 101 may be located on one side or at least on both sides of the second sub-electrode block 201.

[0046] In some embodiments, the first sub-electrode block 101 and the corresponding second sub-electrode block 201 form an electrode block, and the multiple electrode blocks are arranged in multiple rows and columns.

[0047] Optionally, the display panel can form a structure of multiple electrode blocks during the fabrication of the touch electrodes 10, with the multiple electrode blocks arranged in an array. Each electrode block includes a first sub-electrode block 101 and a second sub-electrode block 201. Some of the first sub-electrode blocks 101 are interconnected to serve as first touch electrodes 11, and some of the first sub-electrode blocks 101 are interconnected to serve as second touch electrodes 12. Some of the second sub-electrode blocks 201 are interconnected to serve as first recognition electrodes 21.

[0048] Optionally, the electrode block is rhomboid in shape.

[0049] In some embodiments, the electrode blocks are in a grid shape. Optionally, both the first sub-electrode block 101 and the second sub-electrode block 201 are in a grid shape. The display panel includes a display functional layer, which includes multiple light-emitting units. The display functional layer is located between the touch electrode 10 and the substrate 100. The orthographic projection of the electrode block grid onto the substrate 100 can be around the orthographic projection of the light-emitting units onto the substrate 100. The orthographic projection of the electrode block grid onto the substrate 100 does not overlap with the orthographic projection of the light-emitting units onto the substrate 100, thereby ensuring good light emission performance of the light-emitting units.

[0050] Figure 7 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention, for reference. Figure 2 , Figure 3 and Figure 7 Optionally, the first identification electrode includes at least one first electrode unit 211, and the first electrode unit 211 includes at least one second sub-electrode block 201. In some embodiments, the first electrode unit 211 includes at least two second sub-electrode blocks 201, and the second sub-electrode blocks 201 in the first electrode unit 211 are connected in the display area AA. Optionally, the first electrode unit 211 includes at least two second sub-electrode blocks 201 and a third connecting line L3, and the second sub-electrode blocks 201 in the first electrode unit 211 are connected through the third connecting line L3.

[0051] In some optional embodiments of the present invention, the first identification electrode 21 includes at least two first electrode units 211, which are interconnected in the display area AA. Optionally, the first electrode units 211 in the first identification electrode 21 are connected in the display area AA via a third connecting line L3.

[0052] Optionally, the first electrode unit 211 extends in the same direction as the first touch electrode 11 or the second touch electrode 12. Figure 2 , Figure 3 and Figure 7 An example is shown where the first electrode unit 211 extends along the first direction x.

[0053] Continue to refer to Figure 7 In another optional embodiment of the present invention, the display panel further includes at least one first gating module 70, which is connected to at least one first electrode unit 211 and is also connected to the gesture recognition chip 60 via a second signal line 40; the first gating module 70 is configured to connect at least one first electrode unit 211 to the gesture recognition chip 60 during the gesture recognition phase.

[0054] The first gating module 70 may include at least one switching device, such as a thin-film transistor. During the gesture recognition phase, the gesture recognition chip 60 may send a valid level signal to the first gating module 70, causing the first gating module 70 to conduct, thereby connecting the gesture recognition chip 60 to at least one first electrode unit 211, and thus connecting the gesture recognition chip 60 to the first recognition electrode 21. Optionally, the display panel may also include a non-display area, where the first gating module 70 is located.

[0055] In some embodiments, the first gating module 70 is further configured to connect at least two first electrode units 211 during the gesture recognition stage. Thus, the connected at least two first electrode units 211 together constitute the first recognition electrode, resulting in a larger area occupied by the first recognition electrode and making it easier to form an effective electric field. The first gating module 70 can connect at least two first electrode units 211 by connecting them to the same port of the gesture recognition chip 60, or by connecting different first electrode units 211 to different ports of the gesture recognition chip 60 and connecting the different ports of the gesture recognition chip 60 internally.

[0056] Continue to refer to Figure 7 Optionally, the second signal line 40 includes a first sub-signal line 41 and a second sub-signal line 42. The first sub-signal line 41 is connected to the control terminal of the first gating module 70 and the gesture recognition chip 60, respectively. The second sub-signal line 42 is connected to the first terminal of the first gating module 70 and the gesture recognition chip 60, respectively. The second terminal of the first gating module 70 is connected to the first electrode unit 211.

[0057] During the gesture recognition stage, the gesture recognition chip 60 transmits a valid level signal to the control terminal of the first gating module 70 via the first sub-signal line 41, enabling the first gating module 70 to conduct. When the first recognition electrode is the transmitting electrode for gesture recognition, the gesture recognition chip 60 can output a gesture recognition driving signal to the first terminal of the first gating module 70 via the second sub-signal line 42. The first gating module 70 then transmits the gesture recognition driving signal to the first electrode unit 211 of the first recognition electrode. When the first recognition electrode is the receiving electrode for gesture recognition, the gesture recognition sensing signal on the first electrode unit 211 of the first recognition electrode is transmitted to the gesture recognition chip 60 via the first gating module 70. Figure 7 An optional structure of one of the first gating modules 70 in the display panel is illustrated, with the example shown where the first gating module 70 includes two thin-film transistors.

[0058] Continue to refer to Figure 7 Optionally, the display panel further includes at least one second gating module 80. The control terminal of the second gating module 80 is connected to the gesture recognition chip 60, and the second gating module 80 is also connected to at least one touch electrode 10. The second gating module 80 is configured to connect the gesture recognition chip 60 to the at least one touch electrode 10 during the gesture recognition phase. In this case, the at least one touch electrode 10 is multiplexed as the second recognition electrode 22 for gesture recognition.

[0059] The second gating module 80 may include at least one switching device, such as a thin-film transistor. During the gesture recognition phase, the gesture recognition chip 60 may send a valid level signal to the second gating module 80, causing the second gating module 80 to conduct, thereby establishing a connection between the gesture recognition chip 60 and the touch electrode 10. Optionally, the display panel may also include a non-display area, where the second gating module 80 is located.

[0060] In some embodiments, the second gating module 80 is connected to at least two first touch electrodes 11. The second gating module 80 is also configured to connect at least two first touch electrodes 11 during the gesture recognition phase, and the first touch electrodes 11 connected to the second gating module 80 are reused as gesture recognition electrodes during the gesture recognition phase. Specifically, during the gesture recognition phase, the touch chip does not work and does not output signals to the touch electrodes. Correspondingly, the touch electrodes do not send signals back to the touch chip. Therefore, the touch electrodes can be reused as gesture recognition electrodes during the gesture recognition phase.

[0061] In other embodiments, the second gating module 80 is connected to at least two second touch electrodes 12, and the second gating module 80 is also configured to connect at least two second touch electrodes 12 during the gesture recognition phase, and the second touch electrodes 12 connected to the second gating module 80 are reused as gesture recognition electrodes during the gesture recognition phase.

[0062] In other embodiments, the second gating module 80 is connected to at least one first touch electrode 11 and at least one second touch electrode 12 respectively; the second gating module 80 is also configured to connect at least one first touch electrode 11 and at least one second touch electrode 12 during the gesture recognition stage; the first touch electrode 11 and the second touch electrode 12 connected to the second gating module 80 are reused as gesture recognition electrodes during the gesture recognition stage.

[0063] In this way, at least two connected touch electrodes 10 are reused as the second recognition electrode in the gesture recognition electrode, making the second recognition electrode occupy a larger area and making it easier to form an effective electric field.

[0064] Optionally, the display panel also includes a third signal line, through which the second gating module 80 and the gesture recognition chip 60 are connected. Optionally, the third signal line is located in the non-display area.

[0065] In some embodiments, the third signal line includes a third sub-signal line 91 and a fourth sub-signal line 92. The third sub-signal line 91 is connected to the control terminal of the second gating module 80 and the gesture recognition chip 60, respectively. The fourth sub-signal line 92 is connected to the first terminal of the second gating module 80 and the gesture recognition chip 60, respectively. The second terminal of the second gating module 80 is connected to the control electrode 10.

[0066] During the gesture recognition phase, the gesture recognition chip 60 transmits a valid level signal to the control terminal of the second gating module 80 via the third sub-signal line 91, enabling the second gating module 80 to conduct. When at least one touch electrode 10 is multiplexed as the second recognition electrode 22, and the second recognition electrode 22 is the transmitting electrode for gesture recognition, the gesture recognition chip 60 can output a gesture recognition driving signal to the first terminal of the second gating module 80 via the fourth sub-signal line 92. The second gating module 80 then transmits the gesture recognition driving signal to the second recognition electrode 22. When at least one touch electrode 10 is multiplexed as the second recognition electrode 22, and the second recognition electrode 22 is the receiving electrode for gesture recognition, the gesture recognition sensing signal on the second recognition electrode 22 is transmitted to the gesture recognition chip 60 via the second gating module 80.

In the second identification electrode 22, at least a portion of adjacent second sub-electrode blocks 201 are connected by the fourth connecting line L4. In some embodiments, the fourth connecting line L4 is located in the same layer as the first connecting line L1 and is insulated from it; optionally, the fourth connecting line L4 is parallel to the first connecting line L1; in other embodiments, the fourth connecting line L4 is in the same layer as the second connecting line L2 and is insulated from it; optionally, the fourth connecting line L4 is parallel to the second connecting line L2.

Optionally, the first recognition electrode 21 is a gesture recognition receiving electrode, and the second recognition electrode 22 is a gesture recognition transmitting electrode. In this way, the gesture recognition receiving electrode is located on at least both sides of the gesture recognition transmitting electrode, ensuring that the electric field formed by the gesture recognition receiving electrode and the gesture recognition transmitting electrode is in a specific direction, thereby realizing gesture recognition.

[0070] like Figure 10 and Figure 11 As shown, in some optional embodiments of the present invention, the orthographic projection of the first identification electrode 21 on the substrate 100 is located around the orthographic projection of the second identification electrode 22 on the substrate 100.

[0075] The third gating module 90 may include at least one switching device, such as a thin-film transistor. During the gesture recognition phase, the gesture recognition chip 60 may send a valid level signal to the third gating module 90, causing the third gating module 90 to conduct, thereby connecting the gesture recognition chip 60 to at least one second electrode unit 221, and further connecting the gesture recognition chip 60 to the second recognition electrode 22, as well as connecting different second electrode units 221 within the second recognition electrode 22. Optionally, the display panel may also include a non-display area, where the third gating module 90 is located.

[0076] In some embodiments, the third gating module 90 is further configured to connect at least two second electrode units 221 during the gesture recognition stage. Thus, the connected at least two second electrode units 221 together constitute the second recognition electrode 22, resulting in a larger area occupied by the second recognition electrode 22 and making it easier to form an effective electric field. The third gating module 90 can connect at least two second electrode units 221 by connecting them to the same port of the gesture recognition chip 60, or by connecting different second electrode units 221 to different ports of the gesture recognition chip 60 and connecting the different ports of the gesture recognition chip 60 internally.
