In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0051] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0052] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0053] It should be noted that the transistor in the embodiment of the present application can be an N-type transistor or a P-type transistor. For an N-type transistor, the on-level is a high level and the off-level is a low level. That is, when the gate of the N-type transistor is at a high level, the first and second poles thereof are connected, and when the gate of the N-type transistor is at a low level, the first and second poles thereof are disconnected. For a P-type transistor, the on-level is a low level and the off-level is a high level. That is, when the control pole of the P-type transistor is at a low level, the first and second poles thereof are connected, and when the control terminal of the P-type transistor is at a high level, the first and second poles thereof are disconnected. In a specific implementation, the gate of each of the above-mentioned transistors is used as its control pole, and, according to the signal of the gate of each transistor and its type, the first pole thereof can be used as the source and the second pole as the drain, or the first pole thereof can be used as the drain and the second pole as the source, and no distinction is made here. In addition, the on-level and the off-level in the embodiment of the present invention are both general terms, and the on-level refers to any level that can turn on the transistor, and the off-level refers to any level that can turn off / turn off the transistor.

[0054] In the embodiments of the present application, the term “electrically connected” may refer to a direct electrical connection between two components, or may refer to an electrical connection between two components via one or more other components.

[0055] In the embodiment of the present application, the first node, the second node and the third node are only defined for the convenience of describing the circuit structure, and the first node, the second node and the third node are not actual circuit units.

[0056] It is obvious to those skilled in the art that various modifications and changes can be made in the present application without departing from the spirit or scope of the present application. Therefore, the present application is intended to cover modifications and changes of the present application that fall within the scope of the corresponding claims (technical solutions for protection) and their equivalents. It should be noted that the implementation methods provided in the embodiments of the present application can be combined with each other without contradiction.

[0057] Before describing the technical solutions provided by the embodiments of the present application, in order to facilitate the understanding of the embodiments of the present application, the present application first specifically describes the problems existing in the related art:

[0058] As mentioned above, the inventors of the present application have discovered that in the process of rapid development of display technology, when different pixels of the display panel require different display functions or display effects, it usually involves differentiated design of the display panel in different regions. When the display panel is differentiated in different regions, it is often necessary to connect different signal lines to the pixels in different regions to achieve partition control and adjustment. For example, in the context of the entire surface of the display panel sharing the same cathode voltage in the past, a related technology proposes: considering the influence of IR Drop (voltage drop), the display panel can be divided into several regions, so as to provide different cathode voltages for different regions of the display panel according to adjustment requirements. However, after the panel is divided into several regions for separate cathode power supply, the cathode signal lines increase accordingly. The newly added cathode signal lines will increase the difficulty of panel wiring, which will bring about the problem of insufficient wiring space and difficult wiring arrangement.

[0059] In response to the above technical problems, the embodiments of the present application provide a touch display panel, a driving method and a display device, which can solve the problems existing in the related technology that the power signal lines of the first electrodes of several newly added light-emitting devices will increase the wiring difficulty of the panel, and there are insufficient wiring space and difficult routing.

[0060] It should be noted that the embodiments provided in this application are not intended to limit the scope of the disclosure of this application.

[0061] The technical concept of the embodiments of the present application is that the inventor of the present application adopts a multiplexing module to realize the multiplexing of the original touch signal line, so that it transmits the touch signal to the corresponding touch electrode in a time-sharing manner, and transmits the power signal to the first electrode of the light-emitting device in the corresponding partition, that is, the same multiplexed signal line is used to transmit the corresponding power signal or touch signal to the first electrode of the light-emitting device in the corresponding sub-display area and the corresponding touch electrode in a time-sharing manner, so as to realize the partition control of the voltage of the first electrode of the panel light-emitting element, and at the same time effectively optimize the panel routing, reduce the panel signal line and reduce the difficulty of panel wiring, which is conducive to realizing a narrow frame design.

[0062] The following first introduces the touch display panel provided in the embodiment of the present application.

[0063] Figure 1 FIG. 1 shows a schematic diagram of the structure of a touch display panel provided in an embodiment of the present application. Figure 1 As shown, a touch display panel 100 provided in an embodiment of the present application includes at least one sub-display area. Figure 1 The sub-display areas shown include AA1, AA2, AAn, etc. The number n of the sub-display areas can be set in combination with actual display requirements.

[0064] Any of the at least one sub-display area includes a light-emitting device. The first electrodes of the light-emitting devices in each sub-display area are independently powered. The first electrodes of the light-emitting devices in different sub-display areas are electrically connected to the second ends of different multiplexing modules. The touch display panel 100 may also include a substrate. The light-emitting device may include a second electrode, a light-emitting layer, and a first electrode that are located on the substrate and stacked in sequence in a direction away from the substrate. The first electrode and the touch electrode may be located in different film layers. Optionally, one of the first electrode and the second electrode is a cathode and the other is an anode. Optionally, the first electrode is a cathode and the second electrode is an anode.

[0065] The touch display panel 100 further includes touch electrodes (not shown in the figure) corresponding to the above-mentioned sub-display areas, a multiplexing module and multiplexing signal lines.

[0066] The multiplexing module includes a first end, a second end, and a third end. The first end of the multiplexing module is electrically connected to the corresponding multiplexing signal line, the second end of the multiplexing module is electrically connected to the first electrode of the light-emitting device of the corresponding sub-display area, and the third end of the multiplexing module is electrically connected to the corresponding touch electrode. The multiplexing signal line is used to transmit the power signal Elvss_1 and the touch signal TP_1 in time-sharing, and the multiplexing module is used to connect the first end and the second end of the multiplexing module in time-sharing to transmit the power signal Elvss_1, and connect the first end and the third end of the multiplexing module to transmit the touch signal TP_1.

[0067] like Figure 1 Taking the sub-display area AA1 as an example, the first end of MUX1 (multiplexing module 10) is electrically connected to the corresponding multiplexing signal line EN_1, the second end of MUX1 is electrically connected to the first electrode of the light-emitting device in the AA1 area, and the third end of the multiplexing module is electrically connected to the corresponding touch electrode. The multiplexing signal line EN_1 is used to transmit the power signal Elvss_1 and the touch signal TP_1 in time-sharing. In order to ensure the normal touch and display operation of the touch display panel 100, the above-mentioned MUX1 can be used to connect the first end and the second end of MUX1 in time-sharing to transmit the power signal Elvss_1, and connect the first end and the third end of MUX1 to transmit the touch signal TP_1.

[0068] The touch signal TP_1 may be a touch driving signal or a touch sensing signal, which is not limited in the present application. And, in the present embodiment, more specifically, when the multiplexed signal line EN_1 transmits the power signal Elvss_1, the first end and the second end of MUX1 are connected to transmit the power signal Elvss_1 to the first electrode of the light-emitting device in the AA1 area. When the multiplexed signal line EN_1 transmits the touch signal, the first end and the second end of MUX1 are connected to realize the transmission of the touch signal TP_1 between the multiplexed signal line EN_1 and the touch electrode corresponding to the AA1 area.

[0069] A touch display panel 100 provided in an embodiment of the present application includes a plurality of sub-display areas, and any sub-display area includes a light-emitting device. The touch display panel also includes touch electrodes corresponding to the sub-display areas, a multiplexing module, and a multiplexing signal line. Among them, the first end of the multiplexing module is electrically connected to the corresponding multiplexing signal line, the second end of the multiplexing module is electrically connected to the first electrode of the light-emitting device of the corresponding sub-display area, and the third end of the multiplexing module is electrically connected to the corresponding touch electrode. The multiplexing signal line can be used to transmit power signals and touch signals in time-sharing, and the multiplexing module is used to connect the first end and the second end of the multiplexing module in time-sharing to transmit the power signal, and connect the first end and the third end of the multiplexing module to transmit the touch signal. Specifically, the first electrode of the light-emitting device in a sub-display area is connected to the same power signal line, and the first electrodes of the light-emitting devices in different sub-display areas are electrically connected to different power signal lines. The second end of the multiplexing module can be electrically connected to the first electrode of the light-emitting device through the power signal line.

[0070] Compared with the prior art, a touch display panel 100 in an embodiment of the present application utilizes a multiplexed signal line that was originally used only to transmit touch signals to transmit power signals and touch signals in a time-sharing manner, and then uses a multiplexing module to time-sharingly transmit the touch signal output by the multiplexed signal line to the first electrode of the light-emitting device in the corresponding sub-display area, or transmits the touch signal time-sharingly transmitted by the multiplexed signal line to the corresponding touch electrode, thereby realizing time-sharing power supply output to the first electrode of the light-emitting device in the corresponding sub-display area and the corresponding touch electrode through the multiplexed signal line, which can fully realize independent control of power supply to the first electrodes of light-emitting devices in different partitions of the touch display panel while effectively solving the problem of insufficient panel wiring space and difficult wiring layout.

[0071] Please continue to see Figure 1 In some more specific embodiments, such as Figure 1 As shown, in a touch display panel provided in the present application, the multiple sub-display areas may include at least a first sub-display area AA1 and a second sub-display area AAn.

[0072] The touch display panel 100 may include a plurality of multiplexing modules and touch electrodes (not shown in the figure) corresponding to the first sub-display area AA1 and the second sub-display area AAn respectively. The plurality of multiplexing modules may include at least a first multiplexing module 10 (MUX1) and a second multiplexing module 20 (MUXn), the first multiplexing module 10 corresponds to the first sub-display area AA1, and the second multiplexing module 20 corresponds to the second sub-display area AAn.

[0073] The first end of the first multiplexing module 10 is electrically connected to the corresponding multiplexing signal line EN_1, the second end of the first multiplexing module 10 is electrically connected to the first electrode of the light-emitting device in the AA1 area, and the third end of the multiplexing module is electrically connected to the corresponding touch electrode. The multiplexing signal line EN_1 is used to transmit the power signal Elvss_1 and the touch signal TP_1 in time-sharing. In order to ensure the normal touch and display operation of the touch display panel 100, the first multiplexing module 10 can be used to connect the first end and the second end of the first multiplexing module 10 in time-sharing to transmit the power signal Elvss_1, and connect the first end and the third end of the first multiplexing module 10 to transmit the touch signal TP_1.

[0074] The first end of the second multiplexing module 20 is electrically connected to the corresponding multiplexing signal line EN_n, the second end of the second multiplexing module 20 is electrically connected to the first electrode of the light-emitting device in the AAn area, and the third end of the multiplexing module is electrically connected to the corresponding touch electrode. The multiplexing signal line EN_n is used to transmit the power signal Elvss_n and the touch signal TP_n in time-sharing. In order to ensure the normal touch and display operation of the touch display panel 100, the second multiplexing module 20 can be used to connect the first end and the second end of the second multiplexing module 20 in time-sharing to transmit the power signal Elvss_n, and connect the first end and the third end of the second multiplexing module 20 to transmit the touch signal TP_n.

[0075] It should be noted that the touch signals TP_1 and TP_n may be touch driving signals or touch sensing signals, which are not limited in the present application.

[0076] In some more specific embodiments, the power signal provided by the multiplexed signal lines corresponding to different sub-display areas may be determined according to the actual power supply requirements for the first electrodes of the light-emitting devices in each display area. Thus, the power signal Elvss_1 corresponding to the AA1 area is different from the power signal Elvss_n corresponding to the AAn area.

[0077] Exemplarily, in response to the power signal transmitted by the multiplexed signal lines corresponding to different sub-display areas, the power signal Elvss_1 provided to the first electrode of the light-emitting device in the first sub-display area AA1 can be a -3V voltage signal, and the power signal Elvss_n provided to the first electrode of the light-emitting device in the second sub-display area AAn can be a -2.7V voltage.

[0078] It is worth noting that Figure 1 The sub-display areas shown in FIG. 1 are divided vertically, but the present application is not limited thereto. In some other embodiments, for example, Figure 2 In the structural diagram of another touch display panel provided by an embodiment of the present application, the sub-display areas in the touch display panel 100 may also be divided horizontally or in irregular shapes, and the present application does not impose strict restrictions on this.

[0079] In some more specific embodiments, combined with actual display and touch requirements, in order to more reasonably realize the time-sharing output of the touch signal and the power signal by the multiplexed signal line, so as to fully guarantee the normal display and touch operation of the touch display panel 100 of the present application, in the display blank section between two adjacent display frames, the multiplexed signal line transmits the touch signal; in the display frame, the multiplexed signal line transmits the power signal.

[0080] In the field of display panel technology, the above-mentioned display blank section can also be called a V_Blank area. The V_Blank area is usually distributed between display frames. This period can be used to prepare and transmit picture data without actual picture display. In a more specific statement, the above-mentioned V_Blank can be distributed between the last row of pixels in the effective display area writing the data of the previous frame to the first row of pixels writing the data of the next frame.

[0081] In this embodiment, the stage for transmitting the touch signal is set in the V_Blank area, and the stage for transmitting the power signal is set in the actual display frame, so that the touch and contact feedback can fully avoid interference between the display screen and the motherboard, and the normal lighting work of the light-emitting elements in the sub-display area is not affected.

[0082] In some embodiments, more specifically, in combination with the actual touch working principle, the touch signal can be divided into a touch drive signal and a touch sensing signal, the touch drive signal can be used for touch drive scanning, and the touch sensing signal can be used for touch reporting feedback. Based on this, the above touch signal can include a touch drive signal, and in the display blank section V_Blank, the touch drive signal transmitted by the multiplexed signal line corresponding to any sub-display area is transmitted to the corresponding touch electrode through the multiplexing module, so that the touch electrode performs touch scanning after receiving the touch drive signal.

[0083] In some more specific embodiments, the touch signal may include a touch sensing signal. In the display blank section V_Blank, the touch sensing signal of the touch electrode corresponding to any sub-display area may be transmitted to the corresponding multiplexed signal line through the multiplexing module. Furthermore, the multiplexed signal line may also feed back the received touch sensing signal to the corresponding chip to perform operations such as signal analysis and touch coordinate calculation.

[0084] According to some embodiments of the present application, Figure 1 or Figure 2 Optionally, there are multiple sub-display areas in the touch display panel 100, such as AA1, AA2, and AAn sub-display areas. The first electrodes of the light-emitting devices in different sub-display areas are disconnected and insulated. The first electrode can be a cathode of the light-emitting device, or can also be an anode of the light-emitting device, and the present application does not make any specific restrictions on this.

[0085] Continue to see Figure 1 or Figure 2 Optionally, different sub-display areas correspond to different touch electrodes. Different sub-display areas correspond to different multiplexing modules. Different sub-display areas correspond to different multiplexing signal lines. Exemplarily, the AA1 area corresponds to the multiplexing module 10 (MUX1), and the multiplexing signal line corresponding to the AA1 area is the multiplexing signal line EN_1. The AAn area corresponds to the multiplexing module n0 (MUXn), and the multiplexing signal line corresponding to the AAn area is the multiplexing signal line EN_n.

[0086] According to some embodiments of the present application, optionally, in order to facilitate the transmission of corresponding power signals or touch signals to the first electrodes of the corresponding sub-display area light-emitting devices and the corresponding touch electrodes based on the same multiplexed signal line in time-sharing, thereby further reducing wiring settings, at least a portion of the touch electrodes is located in the sub-display area corresponding thereto. For example, at least a portion of the touch electrodes corresponding to the AA1 area may be located in the AA1 area.

[0087] According to some embodiments of the present application, optionally, in order to further optimize panel routing, reduce panel signal lines and reduce panel wiring difficulty, so as to fully achieve a narrow frame, the arrangement direction of the above-mentioned multiple sub-display areas is the same as the arrangement direction of the multiple touch electrodes. Figure 1 If the multiple sub-display areas are arranged in a row direction, then the multiple touch electrodes corresponding to the multiple sub-display areas can also be arranged in a row direction. Figure 2 If the multiple sub-display areas are arranged in a column direction, then the multiple touch electrodes corresponding to the multiple sub-display areas can also be arranged in the column direction.

[0088] In order to facilitate understanding of the structure of the touch driving panel provided in the present application, some specific embodiments are introduced below.

[0089] See also Figure 3 , Figure 3 is a schematic diagram of the structure of another touch display panel provided in an embodiment of the present application. Figure 3 As shown, in some more specific embodiments, in order to better realize the time-sharing transmission of signals of the multiplexed signal line, optionally, the above-mentioned multiplexing module may include a first switch unit and a second switch unit; the control end of the first switch unit is electrically connected to the first control signal line, the first end of the first switch unit is electrically connected to the multiplexed signal line, and the second end of the first switch unit is electrically connected to the first electrode of the light-emitting device of the corresponding sub-display area; the control end of the second switch unit is electrically connected to the second control signal line, the first end of the second switch unit is electrically connected to the multiplexed signal line, and the second end of the second switch unit is electrically connected to the corresponding touch electrode; wherein the first control signal line and the second control signal line are used to output the conduction level in time-sharing.

[0090] Taking the sub-display area AA1 as an example, in order to more reasonably realize the time-sharing transmission of the signal of the multiplexed signal line EN_1, the multiplexing module 10 (MUX1) may specifically include a first switch unit 11 and a second switch unit 12. Figure 3 As shown, the control end of the first switch unit 11 is electrically connected to the first control signal line mux1, the first end of the first switch unit 11 is electrically connected to the multiplexing signal line EN_1, and the second end of the first switch unit 11 is electrically connected to the first electrode of the light-emitting device in the AA1 area. The control end of the second switch unit 12 is electrically connected to the second control signal line mux2, the first end of the second switch unit 12 is electrically connected to the multiplexing signal line EN_1, and the second end of the second switch unit 12 is electrically connected to the touch electrode corresponding to the AA1 area. Among them, the first control signal line mux1 and the second control signal line mux are used to output the conduction level in time-sharing. In addition, the situation of the sub-display area AAn area is similar to that of the AA1 area. For the sake of brevity, this application will not elaborate on this.

[0091] See below Figure 4 , Figure 4 1 is a structural diagram of another touch display panel 100 provided by an embodiment of the present application. In some possible implementations, more specifically, the first switch unit may include a first transistor, and the second switch unit may include a second transistor; the control end of the first transistor is electrically connected to the first control signal line, the first end of the first transistor is electrically connected to the multiplexing signal line, and the second end of the first transistor is electrically connected to the first electrode of the light-emitting device of the corresponding sub-display area; the control end of the second transistor is electrically connected to the second control signal line, the first end of the second transistor is electrically connected to the multiplexing signal line, and the second end of the second transistor is electrically connected to the corresponding touch electrode.

[0092] exist Figure 4In the touch display panel 100 shown in FIG. 1 , taking the sub-display area AA1 as an example, in a more specific application scenario, the first switch unit 11 may include a first transistor M11, and the second switch unit 12 may include a second transistor M12. Figure 4 , the control end of the first transistor M11 is electrically connected to the first control signal line mux1, the first end of the first transistor M11 is electrically connected to the multiplexing signal line EN_1, and the second end of the first transistor M11 is electrically connected to the first electrode of the light-emitting device in the AA1 area. The control end of the second transistor M12 is electrically connected to the second control signal line mux2, the first end of the second transistor M12 is electrically connected to the multiplexing signal line EN_1, and the second end of the second transistor M12 is electrically connected to the touch electrode corresponding to the AA1 area. The first control signal line mux1 and the second control signal line mux are used to output the conduction level in a time-sharing manner.

[0093] It is worth noting that Figure 4 The transistors shown in the figure are all P-type transistors, and accordingly, the conduction level output by the first control signal line mux1 and the second control signal line mux2 is a low level. However, in some other embodiments, the first transistor and the second transistor may also be specifically N-type transistors, and this application does not make strict restrictions on this.

[0094] It should be noted that, in addition to the above Figure 4 In addition to the listed transistors, the touch display panel 100 of the present application may also include other transistors, and the present application does not impose any specific limitation on this.

[0095] In order to more intuitively understand the working process of the multiplexing module and the principle of signal time-sharing output in this application, please refer to the following Figure 5 , Figure 5 This is a timing diagram of relevant signals in a touch display panel provided in an embodiment of the present application.

[0096] like Figure 5 As shown, in some more specific implementations, combined with actual touch requirements, optionally, the above touch signal may include a touch drive signal or a touch sensing signal. In the display blank section V_Blank area between two adjacent display frames, the second switch unit is turned on under the control of the on-level of the second control signal line mux2, and the touch drive signal of the multiplexed signal line is transmitted to the corresponding touch electrode through the second switch unit, or the touch sensing signal of the corresponding touch electrode is transmitted to the multiplexed signal line through the second switch unit. In the display frame, the second switch unit is turned off under the control of the off-level of the second control signal line mux2.

[0097] And, in some more specific embodiments, in a display blank section between two adjacent display frames, the first switch unit is turned off under the control of the cut-off level of the first control signal line mux1. In a display frame, the first switch unit is turned on under the control of the on-level of the first control signal line mux1, and the power signal of the multiplexed signal line is transmitted to the first electrode of the light-emitting device of the corresponding sub-display area through the first switch unit.

[0098] Combination Figure 5 The timing is shown in the figure. Figure 5 In the field of display technology, the TE signal can be called a synchronization signal, and the display blank section V_Blank area corresponds to the stage where the TE signal is at a high level. In this embodiment, the on level is a low level, and the off level is a high level.

[0099] Specifically, in the display blank section V_Blank area between two adjacent display frames, that is, when the TE signal is a high-level signal, the first control signal line mux1 provides a high level, and the first switch unit is turned off under the control of the first control signal line mux1. The second control signal line mux2 provides a conduction level, and the second switch unit is turned on under the control of the second control signal line mux2. In this process, the touch drive signal of the multiplexed signal line EN_i is transmitted to the corresponding touch electrode through the second switch unit, or the touch sensing signal of the corresponding touch electrode is transmitted to the multiplexed signal line EN_i through the second switch unit.

[0100] In the display frame, the first switch unit is turned on under the control of the on-level of the first control signal line mux1, and the power signal of the multiplexed signal line EN_i is transmitted to the first electrode of the light-emitting device of the corresponding sub-display area through the first switch unit. The second switch unit is turned off under the control of the off-level of the second control signal line mux2. Among them, EN_i is a multiplexed signal line corresponding to any sub-display area (such as the aforementioned AA1 area or AAn area), and this embodiment does not specifically limit this.

[0101] In some more specific implementations, in order to further meet the requirements of the touch display panel for a high reporting rate, it is also possible to consider making full use of the available time period in the display frame for touch signal transmission. Optionally, in the present application, a sub-display area includes a pixel circuit and n1 light-emitting control signal lines. The pixel circuit can be as follows: Figure 6 The pixel circuit of the 7T1C structure shown in the figure, or in some other embodiments, the pixel circuit can also be other structures, such as 8T1C, 8T2C, etc., which are not specifically limited here. The pixel circuit is electrically connected to the second electrode of the light-emitting device, and the light-emitting control signal line is electrically connected to the pixel circuit for transmitting the light-emitting control signal. The light-emitting control signal can correspond to Figure 7The EM signal in . n1 is a positive integer, and n1 is greater than or equal to .

[0102] When n1 is equal to 1, during a non-enable level period of a light emitting control signal transmitted by a light emitting control signal line of a sub-display area, a multiplexed signal line corresponding to the sub-display area transmits a touch signal.

[0103] When n1 is greater than 1, in the first time period when the non-enable levels of the light-emitting control signals transmitted by n1 light-emitting control signal lines in a sub-display area overlap, the multiplexed signal line corresponding to the sub-display area transmits a touch signal; in the second time period when the light-emitting control signal transmitted by any light-emitting control signal line in a sub-display area is at the enable level, the multiplexed signal line corresponding to the sub-display area transmits a power signal.

[0104] To facilitate understanding of the first and second time periods, please refer to Figure 7 , Figure 7 is another timing diagram of related signals in a touch display panel provided by an embodiment of the present application, Figure 8 Corresponding to the case where n1 is greater than 1. Figure 7 In the stage shown, the TE signal continuously provides a low level, and the stage in which the TE signal is at a low level may correspond to the stage in which the display frame is located. In this embodiment, the enable level of the light emitting control signal is a low level, and the non-enable level of the light emitting control signal is a high level.

[0105] like Figure 7 As shown, specifically, if a sub-display area includes a light-emitting device connected to the pixel circuit of the mth row, and a light-emitting device connected to the pixel circuit of the m+1th row, at this time, n1=2, and the n1 light-emitting control signal lines include a light-emitting control signal line EM_m and a light-emitting control signal line EM_m+1. The pixel circuit of the mth row is electrically connected to the light-emitting control signal line EM_m, and is used to drive the light-emitting device of the pixel row to emit light when the light-emitting control signal line EM_m transmits the enable level of the light-emitting control signal. The pixel circuit of the m+1th row is electrically connected to the light-emitting control signal line EM_m+1, and is used to drive the light-emitting device of the pixel row to emit light when the light-emitting control signal line EM_m+1 transmits the enable level of the light-emitting control signal.

[0106] Figure 7 In the above, the first time period T1 is a stage in which both the light-emitting control signal line EM_m and the light-emitting control signal line EM_m+1 provide a non-enable level. In this T1 stage, the multiplexed signal line corresponding to the sub-display area transmits a touch signal. Correspondingly, the above second time period, that is, a time period in which any one of the light-emitting control signal lines EM_m and the light-emitting control signal line EM_m+1 provides an enable level. In this second time period, the multiplexed signal line corresponding to the sub-display area transmits a power signal.

[0107] For some possible implementations, see Figure 8 , Figure 8 is a schematic diagram of the structure of another touch display panel provided in an embodiment of the present application.

A binding pad (not shown in the figure) is provided in the first non-display area NA1, and the binding pad may be used for binding and connecting with a driver chip. A plurality of sub-display areas (AA1, AA2 to AAn) in the display area AA are arranged in sequence with the first non-display area along a first direction Y, and the second non-display area NA2, the sub-display area (AA1, AA2 to AAn) and the third non-display area NA3 are arranged in sequence along a second direction X, and the first direction Y intersects with the second direction X.

In the display area AA, the number of the plurality of sub-display areas can be set according to actual conditions, and the first direction Y can also be the row direction.

[0110] According to some embodiments of the present application, optionally, in order to facilitate the use of the same multiplexed signal line to transmit the corresponding power signal or touch signal to the first electrode of the corresponding sub-display area light-emitting device and the corresponding touch electrode in time-sharing, so as to further reduce wiring to save panel wiring space and reduce wiring difficulty, there are multiple sub-display areas in the touch display panel, and the arrangement direction of the display area and the non-display area where the multiplexing module is located intersects with the arrangement direction of the multiple sub-display areas.

[0111] For example, see Fig. 9There are multiple sub-display areas in the touch display panel 100, including n sub-display areas such as AA1, AA2 to AAn, and the arrangement direction of the n sub-display areas such as AA1, AA2 to AAn is the second direction X. The multiplexing modules corresponding to the multiple sub-display areas are located in the first non-display area NA1. The display area (the area where AA1, AA2 to AAn are located) and the first non-display area NA1 where the multiplexing module is located are arranged in the first direction Y, and the first direction Y intersects with the second direction X.

[0112] According to some embodiments of the present application, further, the arrangement direction of the display area and the non-display area where the multiplexing module is located may also be perpendicular to the arrangement direction of the plurality of sub-display areas. In combination with the above example, the first direction Y is perpendicular to the second direction X.

The driver chip 200 may specifically include a touch driver chip. And, the multiplexing module and the multiplexed signal line can both be located in the first non-display area NA1. Among them, a binding pad (not shown in the figure) can be provided in the first non-display area NA1, and the binding pad can be used to bind and connect with the driver chip 200. The sub-display area and the first non-display area NA1 are arranged in sequence along a first direction (for example, a column direction).

[0114] It should be added that, in some other feasible embodiments, the multiplexing module and the multiplexing signal line may also be located in the second non-display area or the third non-display area, and the present application does not impose specific restrictions on this. In some more specific embodiments, the display area and the second non-display area and / or the third non-display area are arranged along the second direction (e.g., the row direction).

[0115] See below Fig.11 , Fig.11It is another touch display panel provided by the embodiment of the present application. In some more specific embodiments, combined with the distribution of touch electrodes in the actual touch display panel, in order to achieve the partition control of the voltage of the first electrode of the panel light-emitting element, more effectively optimize the panel routing, reduce the panel signal line and reduce the difficulty of panel wiring, the touch display panel 100 includes a plurality of touch drive channels 30 extending along the first direction Y and arranged at intervals along the second direction X, and a touch drive channel 30 includes a plurality of touch drive electrodes Tx arranged and electrically connected along the first direction Y.
