[0041] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The embodiments can be implemented in a plurality of different forms. A person skilled in the art can easily understand the fact that the method and content can be transformed into other forms without departing from the purpose and scope of the present invention. Therefore, the present invention should not be interpreted as being limited to the contents described in the following embodiments. In the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other arbitrarily.

[0042] In the drawings, the size of one or more components, the thickness of a layer, or an area is sometimes exaggerated for the sake of clarity. Therefore, one embodiment of the utility model is not necessarily limited to the size, and the shape and size of one or more components in the drawings do not reflect the true proportion. In addition, the drawings schematically show ideal examples, and one embodiment of the utility model is not limited to the shapes or values ​​shown in the drawings.

[0043] The ordinal numbers such as "first", "second", "third" and the like in this specification are provided to avoid confusion of constituent elements, rather than to limit the quantity. The "plurality" in this utility model means two or more.

[0044] In this specification, for the sake of convenience, the words and phrases indicating the orientation or positional relationship such as "middle", "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like are used to illustrate the positional relationship of the constituent elements with reference to the drawings. This is only for the convenience of describing this specification and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. The positional relationship of the constituent elements is appropriately changed according to the orientation of the constituent elements being described. Therefore, it is not limited to the words and phrases described in the specification and can be appropriately replaced according to the circumstances.

[0045] In this specification, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, or a detachable connection, or an integral connection; it can be a mechanical connection, or a connection; it can be a direct connection, or an indirect connection through an intermediate, or the internal communication of two elements. For ordinary technicians in this field, the meanings of the above terms in this utility model can be understood according to the circumstances.

[0046] In this specification, a transistor refers to an element including at least three terminals: a gate (gate electrode), a drain, and a source. A transistor has a channel region between a drain (drain electrode terminal, drain region, or drain electrode) and a source (source electrode terminal, source region, or source electrode), and current can flow through the drain, the channel region, and the source. In this specification, a channel region refers to a region where current mainly flows.

[0047] In this specification, the first electrode may be a drain electrode, the second electrode may be a source electrode, or the first electrode may be a source electrode, the second electrode may be a drain electrode. In addition, the gate electrode may also be referred to as a control electrode. In the case of using transistors with opposite polarities or in the case of a change in the direction of current during circuit operation, the functions of the "source electrode" and the "drain electrode" are sometimes interchanged. Therefore, in this specification, the "source electrode" and the "drain electrode" may be interchanged.

[0048] In this specification, "electrical connection" includes the case where components are connected together through an element having some electrical function. There is no particular limitation on the "element having some electrical function" as long as it can transmit electrical signals between connected components. Examples of "element having some electrical function" include not only electrodes and wiring, but also switching elements such as transistors, resistors, inductors, capacitors, and other elements having multiple functions.

[0049] In this specification, "parallel" means a state where the angle formed by two straight lines is greater than -10° and less than 10°, and therefore, also includes a state where the angle is greater than -5° and less than 5°. In addition, "perpendicular" means a state where the angle formed by two straight lines is greater than 80° and less than 100°, and therefore, also includes a state where the angle is greater than 85° and less than 95°.

[0050] In this specification, circles, ellipses, triangles, rectangles, trapezoids, pentagons or hexagons are not in the strict sense, but may be approximate circles, approximate ellipses, approximate triangles, approximate rectangles, approximate trapezoids, approximate pentagons or approximate hexagons, etc. There may be some small deformations caused by tolerances, such as chamfers, arc edges and deformations.

[0051] In this specification, "approximately" and "substantially" mean that the limits are not strictly defined and the process and measurement errors are allowed. In the present utility model, "substantially the same" means that the values ​​differ by less than 10%.

[0052] In this specification, A extends along direction B means that A may include a main part and a secondary part connected to the main part, the main part is a line, line segment or strip-shaped body, the main part extends along direction B, and the length of the main part extending along direction B is greater than the length of the secondary part extending along other directions. In this specification, "A extends along direction B" means "the main part of A extends along direction B".

[0053] In this specification, "A and B are of the same layer structure" means that A and B are formed simultaneously by the same patterning process. "The same layer" does not always mean that the thickness of the layer or the height of the layer is the same in the cross-sectional view. "The orthographic projection of A includes the orthographic projection of B" means that the orthographic projection of B falls within the orthographic projection range of A, or the orthographic projection of A covers the orthographic projection of B.

[0054] In order to better meet people's needs for various functions and better screen experience (for example, a display screen with an ultra-high screen-to-body ratio), narrow-frame display screen design has gradually become the mainstream form of display devices.

[0056] In this example, A and B being adjacent means that A and B are close to each other and there is no other circuit structure between them.

[0057] The display panel provided in this embodiment can optimize the arrangement of the first electrostatic release circuit in the first frame area by setting the first electrostatic release circuit in the second fan-out area, which is beneficial to optimizing the wiring space in the first frame area and thus conducive to narrow frame design.

[0059] In some exemplary embodiments, the plurality of first electrostatic discharge circuits may further include: a third group of electrostatic discharge circuits and a fourth group of electrostatic discharge circuits located in the second fan-out region.

[0063] The solution of this embodiment is described below by means of some examples.

For example, the first frame area B1 may be the lower frame area of ​​the display panel; the second frame area B2 may include: a left frame area, a right frame area and an upper frame area of ​​the display panel.

For example, the display area can be other shapes such as a rectangle. In some examples, the display panel can be a flexible panel, and thus the display panel can be deformable, such as curling, bending, folding or rolling up.

The FMLOC structure is based on the working principle of mutual capacitance detection. Generally, two layers of metal are used to form a driving (Tx) electrode and a sensing (Rx) electrode. The driving chip (IC) realizes the touch action by detecting the mutual capacitance between the driving electrode and the sensing electrode. The FSLOC structure is based on the working principle of self-capacitance (or voltage) detection. Generally, a single layer of metal is used to form a touch electrode. The integrated circuit realizes the touch action by detecting the self-capacitance (or voltage) of the touch electrode.

The plurality of gate lines GL may be electrically connected to the plurality of sub-pixels P, and the plurality of gate lines GL may be configured to provide pixel control signals to the plurality of sub-pixels P. For example, the pixel control signal may include a scan signal, or may include a scan signal and a light emitting control signal, or may include a scan signal, a reset control signal, and a light emitting control signal.

[0068] In some examples, such as Figure 1As shown, the first direction X may be the extension direction (e.g., row direction) of the gate lines GL in the display area AA, and the second direction Y may be the extension direction (e.g., column direction) of the data lines DL in the display area AA. The first direction X and the second direction Y may intersect each other, for example, may be perpendicular to each other.

[0069] In some examples, a pixel unit of display area AA may include three sub-pixels, and the three sub-pixels may be a first sub-pixel emitting a first color light (e.g., red light), a second sub-pixel emitting a second color light (e.g., green light), and a third sub-pixel emitting a third color light (e.g., blue light). However, this embodiment is not limited to this. In some examples, a pixel unit may include four sub-pixels, and the four sub-pixels may be a sub-pixel emitting red light, a sub-pixel emitting green light, a sub-pixel emitting blue light, and a sub-pixel emitting white light. For another example, a pixel unit may include four sub-pixels, and the four sub-pixels may include a sub-pixel emitting red light, a sub-pixel emitting blue light, and two sub-pixels emitting green light.

[0070] In some examples, a sub-pixel may include: a pixel circuit and a light-emitting element electrically connected to the pixel circuit. The pixel circuit may include multiple transistors and at least one capacitor. For example, the pixel circuit may be a 3T1C, 4T1C, 5T1C, 5T2C, 6T1C, 7T1C or 8T1C structure. Wherein, T in the above circuit structure refers to a thin film transistor, C refers to a capacitor, the number before T represents the number of thin film transistors in the circuit, and the number before C represents the number of capacitors in the circuit. In some examples, the multiple transistors in the pixel circuit may include P-type transistors and N-type transistors. In other examples, the multiple transistors in the pixel circuit may be P-type transistors or may be N-type transistors. Using the same type of transistors in the pixel circuit can simplify the process flow, reduce the process difficulty of the display panel, and improve the yield of the product.

[0071] In some examples, the shape of the light-emitting element of the sub-pixel can be a rectangle, a rhombus, a pentagon, or a hexagon. When a pixel unit includes three sub-pixels, the light-emitting elements of the three sub-pixels can be arranged in parallel horizontally, vertically, or in a triangle; when a pixel unit includes four sub-pixels, the light-emitting elements of the four sub-pixels can be arranged in parallel horizontally, vertically, or in a square. However, this embodiment is not limited to this.

The color of the light emitted by the light-emitting element may be determined as required. In some examples, the light-emitting element may include: an anode, a cathode, and an organic light-emitting layer located between the anode and the cathode. The anode of the light-emitting element may be electrically connected to the corresponding pixel circuit. However, this embodiment is not limited to this.

[0073] Figure 2 is an equivalent circuit diagram of a pixel circuit of at least one embodiment of the present utility model. The pixel circuit of this example is described by taking an 8T1C structure as an example. In some examples, such as Figure 2 As shown, the pixel circuit of this example may include eight transistors (i.e., the first transistor T1 to the eighth transistor T8) and a storage capacitor Cst.

The active layer of the low-temperature polysilicon thin film transistor adopts low-temperature polysilicon (LTPS), and the active layer of the oxide thin film transistor adopts an oxide semiconductor (Oxide). Low-temperature polysilicon thin film transistors have the advantages of high mobility and fast charging, and oxide thin film transistors have the advantages of low leakage current. Integrating low-temperature polysilicon thin film transistors and oxide thin film transistors on a display panel to form a low-temperature polycrystalline oxide (LTPS+Oxide) display panel can take advantage of the advantages of both, achieve low-frequency driving, reduce power consumption, and improve display quality.

The gate of the second transistor T2 is electrically connected to the second scan line GL2, the first electrode of the second transistor T2 is electrically connected to the third node N3, and the second electrode of the second transistor T2 is electrically connected to the first node N1. The gate of the fifth transistor T5 is electrically connected to the light emission control line EML, the first electrode of the fifth transistor T5 is electrically connected to the first power line PL1, and the second electrode of the fifth transistor T5 is electrically connected to the second node N2.

[0079] Below Figure 2 The working process of the pixel circuit shown in FIG. 1 is described as follows. The first transistor T1, the third transistor T3 to the eighth transistor T8 of the pixel circuit are P-type transistors, and the second transistor T2 is an N-type transistor.

[0080] In some examples, during a frame display period, the operation process of the pixel circuit may include at least: a first stage, a second stage, a third stage, and a fourth stage.

[0081] The first stage is called the first reset stage. The second reset control signal RESET2 provided by the second reset control line RST2 is a low-level signal, which turns on the seventh transistor T7 and the eighth transistor T8; the second scan signal SCAN2 provided by the second scan line GL2 is a high-level signal, which turns on the second transistor T2. The eighth transistor T8 is turned on, so that the third initial signal provided by the third initial signal line INIT3 is provided to the second node N2. The seventh transistor T7 is turned on, so that the second initial signal provided by the second initial signal line INIT2 is provided to the fourth node N4, and the fourth node N4 is initialized. The first scan signal SCAN1 provided by the first scan line GL1 is a high-level signal, the first reset control signal RESET1 provided by the first reset control line RST1 is a high-level signal, and the light control signal EM provided by the light control line EML is a high-level signal, so that the fourth transistor T4, the first transistor T1, the fifth transistor T5 and the sixth transistor T6 are turned off. In this stage, the light-emitting element EL does not emit light.

[0082] The second stage is called the second reset stage. The first reset control signal RESET1 provided by the first reset control line RST1 is a low-level signal, and the first transistor T1 is turned on; the second scan signal SCAN2 provided by the second scan line GL2 is a high-level signal, and the second transistor T2 is turned on. The first transistor T1 and the second transistor T2 are turned on, so that the first initial signal line provided by the first initial signal line INIT1 is provided to the first node N1, and the first node N1 is initialized. The second reset control signal RESET2 provided by the second reset control line RST2 is a high-level signal, the first scan signal SCAN1 provided by the first scan line GL1 is a high-level signal, and the light-emitting control signal EM provided by the light-emitting control line EML is a high-level signal, so that the seventh transistor T7, the eighth transistor T8, the fourth transistor T4, the fifth transistor T5 and the sixth transistor T6 are turned off. In this stage, the light-emitting element EL does not emit light.

[0083] The third stage is called the data writing stage or the threshold compensation stage. The first scanning signal SCAN1 provided by the first scanning line GL1 is a low level signal, and the fourth transistor T4 is turned on; the second scanning signal SCAN2 provided by the second scanning line GL2 is a high level signal, and the second transistor T2 is turned on. In this stage, the first electrode of the storage capacitor Cst is at a low level, and the third transistor T3 is turned on. The second transistor T2, the fourth transistor T4 and the third transistor T3 are turned on, so that the data voltage Vdata output by the data line DL is provided to the first node N1 through the second node N2, the turned-on third transistor T3, the third node N3 and the turned-on second transistor T2, and the difference between the data voltage Vdata output by the data line DL and the threshold voltage of the third transistor T3 is charged into the storage capacitor Cst, and the voltage of the first electrode (i.e., the first node N1) of the storage capacitor Cst is Vdata-|Vth|, where Vdata is the data voltage output by the data line DL, and Vth is the threshold voltage of the third transistor T3. The first reset control signal RESET1 provided by the first reset control line RST1 is a high level signal, the second reset control signal RESET2 provided by the second reset control line RST2 is a high level signal, and the light control signal EM provided by the light control line EML is a high level signal, so that the first transistor T1, the seventh transistor T7, the eighth transistor T8, the fifth transistor T5 and the sixth transistor T6 are disconnected.

[0084] In the fourth stage, the light control signal EM provided by the light control line EML can be switched from a high level signal to a low level signal, so that the fifth transistor T5 and the sixth transistor T6 are turned on. The second scan signal SCAN2 provided by the second scan line GL2 is a low level signal, so that the second transistor T2 is turned off. The first scan signal SCAN1 provided by the first scan line GL1, the first reset control signal RESET1 provided by the first reset control line RST1, and the second reset control signal RESET2 provided by the second reset control line RST2 are high level signals, so that the fourth transistor T4, the first transistor T1, the seventh transistor T7, and the eighth transistor T8 are turned off. The first voltage signal VDD output by the first power line PL1 provides a driving voltage to the anode of the light emitting element EL through the turned-on fifth transistor T5, the third transistor T3, and the sixth transistor T6, so as to drive the light emitting element EL to emit light.

[0085] During the driving process of the pixel circuit, the driving current flowing through the third transistor T3 is determined by the voltage difference between its gate and the first electrode. Since the voltage of the first node N1 is Vdata-|Vth|, the driving current of the third transistor T3 is:

[0086] I=K×(Vgs-Vth) 2 =K×[(VDD-Vdata+|Vth|)-Vth]2 =K×[VDD-Vdata] 2 ;

[0087] Among them, I is the driving current flowing through the third transistor T3, that is, the driving current driving the light-emitting element, K is a constant, Vgs is the voltage difference between the gate and the first electrode of the third transistor T3, Vth is the threshold voltage of the third transistor T3, Vdata is the data voltage output by the data line DL, and VDD is the first voltage signal output by the first power line PL1.

[0088] It can be seen from the above formula that the current flowing through the light-emitting element has nothing to do with the threshold voltage of the third transistor T3. Therefore, the pixel circuit of this embodiment can better compensate for the threshold voltage of the third transistor T3. Moreover, the pixel circuit provided by this embodiment can improve the poor display caused by low frequency and improve the display effect of the light-emitting element.

This embodiment is not limited to this.

For example, each light emitting element may include: a stacked first electrode 131, an organic light emitting layer 132 and a second electrode 133. The first electrode 131 of the light emitting element may be an anode, and the first electrode 131 may be disposed on the eighth insulating layer 108, and electrically connected to the first transfer electrode 241 through the sixth pixel via hole provided in the eighth insulating layer 108.

The second electrode 133 may be disposed on the organic light emitting layer 132 and connected to the organic light emitting layer 132. The organic light emitting layer 132 may emit light of corresponding colors under the drive of the first electrode 131 and the second electrode 133.

[0098] In some examples, the light-emitting layers of light-emitting elements of different colors may be different. For example, the red light-emitting element includes a red light-emitting layer, the green light-emitting element includes a green light-emitting layer, and the blue light-emitting element includes a blue light-emitting layer. In order to reduce the process difficulty and improve the yield, the hole injection layer and the hole transport layer on one side of the light-emitting layer may use a common layer, and the electron injection layer and the electron transport layer on the other side of the light-emitting layer may use a common layer. In some examples, any one or more of the hole injection layer, the hole transport layer, the electron injection layer, and the electron transport layer can be made by a single process (a single evaporation process or a single inkjet printing process), and isolation is achieved by means of a surface step difference of the formed film layer or by surface treatment. For example, any one or more of the hole injection layer, the hole transport layer, the electron injection layer, and the electron transport layer corresponding to adjacent sub-pixels may be isolated.

The second encapsulation layer 142 may be made of organic materials, for example, it may be a polymer material containing a desiccant or a polymer material that can block water vapor, or it may be a polymer resin, etc. to flatten the surface of the display panel, and it may relieve the stress of the first encapsulation layer 141 and the third encapsulation layer 143, and it may also include a desiccant and other water-absorbing materials to absorb water, oxygen, and other substances that invade the interior.

For example, the first touch conductive layer 151 may include a plurality of first touch electrodes, a plurality of second touch electrodes, and a plurality of first connecting portions. The first touch electrodes and the first connecting portions may be an integral structure connected to each other. The second touch conductive layer 152 may include a plurality of second connecting portions. The second connecting portion may be interconnected with the adjacent second touch electrodes through a via provided in the touch interlayer insulating layer. However, this embodiment is not limited to this. In other examples, the first touch conductive layer may include: a plurality of first touch electrodes, a plurality of second touch electrodes and a plurality of second connecting portions, and the second touch electrodes and the second connecting portions may be an integrated structure connected to each other; the second touch conductive layer may include a plurality of first connecting portions, and the first connecting portions may be connected to adjacent first touch electrodes through vias provided in the touch interlayer insulating layer.

[0118] Figure 6 The figure is an equivalent circuit diagram of a multiplexing circuit according to at least one embodiment of the present invention. Figure 6 In the figure, a multiplexing circuit 311 is used as an example for illustration. In some examples, such as Figure 6 As shown, one multiplexing circuit 311 can be electrically connected to nine multiplexing control lines, one multiplexing data line 411, and multiple data lines (e.g., the first data line DL1 to the ninth data line DL9).

[0119] In some examples, the first multiplexing control line 422a is configured to transmit a first multiplexing control signal, the second multiplexing control line 422b is configured to transmit a second multiplexing control signal, the third multiplexing control line 422c is configured to transmit a third multiplexing control signal, the fourth multiplexing control line 422d is configured to transmit a fourth multiplexing control signal, the fifth multiplexing control line 422e is configured to transmit a fifth multiplexing control signal, the sixth multiplexing control line 422f is configured to transmit a sixth multiplexing control signal, the seventh multiplexing control line 422g is configured to transmit a seventh multiplexing control signal, the eighth multiplexing control line 422h is configured to transmit an eighth multiplexing control signal, and the ninth multiplexing control line 422i is configured to transmit a ninth multiplexing control signal.

[0120] In some examples, the multiplexing circuit 311 may include nine multiplexing control transistors (i.e., the first multiplexing control transistor M1 to the ninth multiplexing control transistor M9). The gates of the nine multiplexing control transistors may be connected to different multiplexing control lines, i.e., the gate of the first multiplexing control transistor M1 is connected to the first multiplexing control line 422a, the gate of the second multiplexing control transistor M2 is connected to the second multiplexing control line 422b, the gate of the third multiplexing control transistor M3 is connected to the third multiplexing control line 422c, the gate of the fourth multiplexing control transistor M4 is connected to the fourth multiplexing control line 422d, the gate of the fifth multiplexing control transistor M5 is connected to the fifth multiplexing control line 422e, the gate of the sixth multiplexing control transistor M6 is connected to the sixth multiplexing control line 422f, the gate of the seventh multiplexing control transistor M7 is connected to the seventh multiplexing control line 422g, the gate of the eighth multiplexing control transistor M8 is connected to the eighth multiplexing control line 422h, and the gate of the ninth multiplexing control transistor M9 is connected to the ninth multiplexing control line 422i.

[0122] Fig. 7A for Figure 5 A partial enlarged schematic diagram of the middle area SS1. Figure 7B for Fig. 7A Schematic diagram of a multiplexing circuit after a second gate metal layer is formed. Fig. 7A and Figure 7B The figure mainly illustrates the positions of some multiplexing control transistors in the two second multiplexing circuits, briefly illustrates the structure of the pixel circuit PX, and omits illustrating the wiring extending along the first direction X to which the pixel circuit PX is connected.

[0123] In some examples, such as Figure 5 , Fig. 7A and Figure 7B As shown, a second multiplexing circuit 31b may correspond to a row of pixel circuits PX. Multiple multiplexing circuits in the second multiplexing circuit 31b may be arranged in sequence along the first direction X, and multiple multiplexing control transistors in each multiplexing circuit may be arranged in sequence along the first direction X.

[0124] The film layer structure of the multiplexing control transistor is described below by taking the multiplexing control transistor M1 as an example. The multiplexing control transistor M1 may include: an active layer M10, a gate electrode M13, a first pole M11, and a second pole M12. The active layer M10 of the multiplexing control transistor M1 may be located in the first semiconductor layer, and the orthographic projection on the substrate may be a rectangle. The gate electrode M11 of the multiplexing control transistor M1 may be located in the first gate metal layer, for example, it may extend at least along the second direction Y. The orthographic projection of the gate electrode M11 on the substrate overlaps with the orthographic projection of the active layer M10 on the substrate, for example, the orthographic projection of the gate electrode M11 on the substrate may pass through the midline of the active layer M10 along the first direction X. The first pole M11 may be connected to the first region of the active layer M10, and the second pole M12 may be connected to the second region of the active layer M10. The first pole M11 and the second pole M12 may be located on both sides of the gate electrode M13 in the first direction X. The first pole M11 and the second pole M12 may be located in the first source and drain metal layer. The first electrode M11 may be connected to the data line DL located at the second source / drain metal layer.

[0125] In some examples, the active layers of multiple multiplexing control transistors in each group of multiplexing circuits can be aligned and arranged along the first direction X. The first electrodes of the nine multiplexing control transistors of a multiplexing circuit can be an integrated structure that is interconnected, and can be located on the side of the multiple multiplexing control lines close to the display area AA. The integrated structure of the first electrodes of the nine multiplexing control transistors of the multiplexing circuit can be connected to the multiplexed data line 411. The multiplexed data line 411 can be located, for example, in the second gate metal layer, or can be located in the first gate metal layer. For example, a plurality of multiplexed data lines can be alternately arranged in the first gate metal layer and the second gate metal layer, and the orthographic projections of the plurality of multiplexed data lines on the substrate may not overlap. The arrangement method of this example can save the gap between adjacent multiplexed data lines, which is conducive to optimizing the arrangement space of the multiplexed data lines.

[0126] In some examples, the multiplexed control lines may be located on a side of the multiplexed circuit away from the display area AA. The multiplexed control lines (e.g., including the first multiplexed control line 422a to the ninth multiplexed control line 422i) may be sequentially arranged in a direction away from the display area AA. For example, the multiplexed control lines may be located in the first source-drain metal layer. The gate electrodes of the nine multiplexed control transistors of the multiplexed circuit may be connected to the corresponding multiplexed control lines.

[0127] The arrangement of the multiplexing control transistors in the first multiplexing circuit is similar to the arrangement of the multiplexing control transistors in the second multiplexing circuit, so it will not be described in detail here.

[0128] The multiplexing circuit of this example is arranged in a stepped manner close to the display area, which can avoid the data line connected to the second pole of the multiplexing control transistor from overlapping with the other signal lines, improve the situation where the data line is interfered by the other signal lines due to parasitic capacitance, and ensure the consistency of the parasitic capacitance between the multiplexed data lines and multiplexed control lines connected by multiple multiplexed control transistors and the other alternating signals. Moreover, the multiple multiplexed control transistors of the multiplexed circuit of this example adopt a unified layout design, which can ensure the consistency of parasitic capacitance between signals, which is conducive to improving the display effect.

[0129] In some examples, such as Figure 5 As shown, the first fan-out area B11 is further provided with a first peripheral power line 43 and second peripheral power lines 44a and 44b. The first peripheral power line 43 may be located on a side of the first group of multiplexing circuits 31a away from the display area AA. In the first fan-out area B11, the second peripheral power lines 44a and 44b may be located on both sides of the first peripheral power line 43 along the first direction X. For example, the first peripheral power line 43 and the second peripheral power lines 44a and 44b may be located in the first source-drain metal layer.

The first peripheral extension portion 431 may extend to the left frame region of the second frame region B2, and the second peripheral extension portion 432 may extend to the right frame region of the second frame region B2.

[0131] In some examples, such as Figure 5 As shown, the first peripheral power line 43 may also include: four first peripheral connection parts connected to the peripheral body part 430, and the four first peripheral connection parts may be located on one side of the peripheral body part 430 close to the bending area B12. The four first peripheral connection parts may be connected to the four groups of first power bending lines of the bending area B12 in a one-to-one correspondence.

[0132] In some examples, such as Figure 5 As shown, the second peripheral power line 44a can extend to the left frame area of ​​the second frame area B2 and be located on the side of the first group of gate drive circuits 25 away from the display area AA; the second peripheral power line 44b can extend to the right frame area of ​​the second frame area B2 and be located on the side of the second group of gate drive circuits 26 away from the display area AA.

[0133] In some examples, such as Figure 5As shown, the first fan-out area B11 may also be provided with a plurality of multiplexed data lines. The plurality of multiplexed data lines may include: a first group of multiplexed data lines 41a and a second group of multiplexed data lines 41b. The first group of multiplexed data lines 41a may be connected to the multiplexing circuit in the first corner area of ​​the second frame area B2 and part of the multiplexing circuit in the first fan-out area B11; the second group of multiplexed data lines 41b may be connected to the multiplexing circuit in the second corner area of ​​the second frame area B2 and another part of the multiplexing circuit in the first fan-out area B11. The first group of multiplexed data lines 41a may be located on the side of the second peripheral power line 44a close to the first peripheral power line 43, and the second group of multiplexed data lines 44b may be located on the side of the second peripheral power line 44b close to the first peripheral power line 43.

[0134] In some examples, such as Figure 5 As shown, the first fan-out area B11 may also be provided with a plurality of peripheral control lines, and the plurality of peripheral control lines may include: a first group of peripheral control lines 42a and a second group of peripheral control lines 42b. The first group of peripheral control lines 42a and the second group of peripheral control lines 42b may be adjacent to each other in the first fan-out area B11 near the bending area B12. The first group of peripheral control lines 42a may extend to the first corner area of ​​the second border area B2, and the second group of peripheral control lines 42b may extend to the second corner area of ​​the second border area B2.

[0135] In some examples, the plurality of peripheral control lines may include: a plurality of drive control lines (for example, including a start signal line, a clock signal line, a voltage line, etc. connected to a gate drive circuit) and a plurality of multiplexing control lines. The plurality of drive control lines in the first group of peripheral control lines 42a may be connected to the first group of gate drive circuits 25, and the plurality of multiplexing control lines in the first group of peripheral control lines 42a may be connected to the multiplexing circuit in the first corner region and part of the multiplexing circuit in the first fan-out region B11. The plurality of drive control lines in the second group of peripheral control lines 42b may be connected to the second group of gate drive circuits 26, and the plurality of multiplexing control lines in the second group of peripheral control lines 42b may be connected to the multiplexing circuit in the second corner region and another part of the multiplexing circuit in the first fan-out region B11. For example, the first group of peripheral control lines 42a and the first group of multiplexing data lines 41a may overlap in their orthographic projections on the substrate. The second group of peripheral control lines 42b and the second group of multiplexing data lines 41b may overlap in their orthographic projections on the substrate. The multiple reused control lines in each group of peripheral control lines may be located on a side of the multiple drive control lines close to the display area AA, which may be beneficial for optimizing the routing path and reducing routing overlap.

[0136] Fig. 8A for Figure 5 A partial enlarged schematic diagram of the middle area SS2. Figure 8B for Fig. 8A Schematic diagram of the first peripheral power line in FIG. Fig. 8A and Figure 8B As shown, the first fan-out area B11 is also provided with a plurality of peripheral touch lines, and the plurality of peripheral touch lines may include a first group of peripheral touch lines 45a and a second group of peripheral touch lines 45b. The orthographic projection of the plurality of peripheral touch lines on the substrate may overlap with the orthographic projection of the first peripheral power line 43 on the substrate. The plurality of peripheral touch lines may be located on the side of the first peripheral power line 43 away from the substrate. The plurality of peripheral touch lines may be located in the touch structure layer, for example, may be located in the first touch conductive layer or the second touch conductive layer, or may be arranged alternately in the first touch conductive layer and the second touch conductive layer.

[0137] In some examples, such as Fig. 8A and Figure 8B As shown, the peripheral main body 430 of the first peripheral power line 43 includes: a first part 430-1 and a second part 430-2 connected to each other along the second direction Y, the second part 430-2 can be located on the side of the first part 430-1 away from the display area AA, and the first part 430-1 can be connected to the first peripheral extension part 431 and the second peripheral extension part 432. The length of the second part 430-2 along the first direction X can be greater than the length of the first part 430-1 along the first direction X, thereby increasing the overlapping area between the peripheral main body 430 of the first peripheral power line 43 and the plurality of peripheral touch lines. In this example, by arranging the first peripheral power line 43 at the periphery of the multiplexing circuit away from the display area AA, and the first peripheral power line 43 and the plurality of peripheral touch lines are overlapped in the first fan-out area, the peripheral touch lines of the first fan-out area B11 can be shielded from interference from the signal lines of the display structure layer, thereby avoiding mutual interference between the peripheral lines of the display structure layer and the touch structure layer.

[0138] Fig.9A for Figure 5 Another partial enlarged schematic diagram of the middle area SS2. Fig. 9B for Fig.9A Schematic diagram of the first gate metal layer, the second gate metal layer and the first source and drain metal layer in FIG. Fig. 9C for Fig.9A Schematic diagram of the second gate metal layer in FIG. Fig.9D for Fig.9A Schematic diagram of the first gate metal layer in FIG. Fig.9A The partially overlapping area of ​​the first peripheral power line 43 and the plurality of peripheral control lines is taken as an example for illustration.

[0139] In some examples, such as 9A to 9DAs shown, at least one peripheral control line 42 of the plurality of peripheral control lines (e.g., a clock signal line connected to a gate driving circuit) may include: a first peripheral line segment 421 and a second peripheral line segment 422 connected to each other. The first peripheral line segment 421 may be located on a side of the first peripheral power line 43 close to the substrate, and the orthographic projection of the first peripheral line segment 421 on the substrate may partially overlap with the orthographic projection of the first peripheral power line 43 on the substrate, and the orthographic projection of the second peripheral line segment 422 on the substrate may not overlap with the orthographic projection of the first peripheral power line 43 on the substrate.

[0140] In some examples, such as 9A to 9D As shown, the first peripheral line segment 421 may include: a first routing line 4211 and a second routing line 4212 located in different conductive layers. For example, the first routing line 4211 may be located in the first gate metal layer, and the second routing line 4212 may be located in the second gate metal layer. The orthographic projection of the first routing line 4211 on the substrate may cover the orthographic projection of the second routing line 4212 on the substrate. The first routing line 4211 and the second routing line 4212 may be connected to the control bending line 520 of the bending area B12 through the first connecting electrode 521, and the first routing line 4211 and the second routing line 4212 may also be connected to the second peripheral line segment 422. Alternatively, the first routing line 4211 and the second routing line 4212 may be connected to the second peripheral line segment 422 through the second connecting electrode 522.

[0141] In some examples, the first connection trace 521 and the second connection electrode 522 may be located in the first source-drain metal layer, the second peripheral line segment 422 may be located in the second source-drain metal layer, and the control bending line 520 may be located in the second source-drain metal layer.

[0142] The peripheral control line of this example can be arranged in the first gate metal layer and the second gate metal layer in the overlapping area with the first peripheral power line, which can reduce the interference with the peripheral touch wiring.

[0143] In some examples, such as Figure 5As shown, the bending area B12 may include a plurality of bending lines. The plurality of bending lines may include: four groups of first power bending lines 53a, 53b, 53c and 53d, two groups of second power bending lines 54a and 54b, a first group of data bending lines 51a, a second group of data bending lines 51b, a group of control bending lines 52, a first group of touch bending lines 55a, a second group of touch bending lines 55b, a first group of detection bending lines 56a and a second group of detection bending lines 56b.

The structure of the second electrostatic discharge circuit may refer to the structure of the first electrostatic discharge circuit, so it will not be repeated here.

[0211] The display panel provided in this example can reduce the space occupied in the first fan-out area by arranging the electrostatic discharge circuit in the second fan-out area, or in the second fan-out area and the second frame area, so as to meet the requirements of using Figure 2 The pixel circuit shown causes the border routing to increase the wiring space requirements for the first fan-out area, which is conducive to realizing a display panel with a narrow border. Moreover, the multiplexing circuit of this example is arranged in a stepped manner close to the display area, which can reduce the interference of the data signal and help ensure the consistency of the parasitic capacitance between signals. In addition, the first peripheral power line in the first fan-out area can shield the routing of the touch structure layer and the display structure layer, which can reduce the mutual interference between signals.
