Technical Field

[0002] In an organic light-emitting display panel, the organic light-emitting display panel includes a pixel circuit. After the data writing stage, the data signal jumps high to couple the high-level power line (VGH), so that the signal of the high-level power line jumps high. Since the high-level power line generates coupling capacitance with the A node and the B node of the pixel circuit, the A node and the B node are pulled high, and then the Q node is overcharged. The potential of the Q node is higher than the value in the normal area, resulting in dark lines. Among them, the A node is the connection node of the input electrode of the driving thin film transistor, the B node is the connection node of the output electrode of the driving thin film transistor, and the Q node is the connection node of the gate of the driving thin film transistor and the storage capacitor (Cst).

[0081] The gate of the fourth transistor T4 is connected to the output terminal Nscan2 of the third driving circuit 20c, the input electrode of the fourth transistor T4 is connected to the first voltage terminal Vi1, and the output electrode of the fourth transistor T4 is connected to the third node Q. The gate of the seventh transistor T7 is connected to the output terminal Pscan2 of the fifth driving circuit 20e, the input electrode of the seventh transistor T7 is connected to the second voltage terminal Vi2, and the output electrode of the seventh transistor T7 is connected to the fourth node C. The gate of the eighth transistor T8 is connected to the output terminal Pscan2 of the fifth driving circuit 20e, the input electrode of the eighth transistor T8 is connected to the third voltage terminal Vi3, and the output electrode of the eighth transistor T8 is connected to the first node A.

[0082] In addition, according to an embodiment, the pixel circuit 10 may further include a boost capacitor Cboost including a first terminal connected to the third node Q and a second terminal connected to the gate of the second transistor T2. The boost capacitor Cboost may increase the voltage of the third node Q.

[0083] like Figure 3 As shown, the third transistor T3 and the fourth transistor T4 may be n-type transistors, and the first transistor T1, the second transistor T2, the fifth transistor T5, the sixth transistor T6, the seventh transistor T7 and the eighth transistor T8 may be p-type transistors. However, this is only exemplary, and at least one of the first transistor T1, the second transistor T2, the fifth transistor T5, the sixth transistor T6, the seventh transistor T7 and the eighth transistor T8 may also be an n-type transistor.

[0084] Please refer to Figure 4The timing of the pixel circuit 10 includes a data writing phase R1. In the data writing phase R1, the first transistor T1 is configured to be turned on under the control of the voltage of the third node Q, the second transistor T2 is configured to be turned on under the control of the low level signal output by the output terminal Pscan of the first driving circuit 20a, and the third transistor T3 is configured to be turned on under the control of the high potential signal output by the output terminal Nscan1 of the second driving circuit 20b. The fourth transistor T4 is configured to be turned off under the control of the low potential signal output by the output terminal Nscan2 of the third driving circuit 20c, the fifth transistor T5 and the sixth transistor T6 are configured to be turned off under the control of the high potential signal output by the output terminal EM of the fourth driving circuit 20d, and the seventh transistor T7 and the eighth transistor T8 are configured to be turned off under the control of the high potential signal output by the output terminal Pscan2 of the fifth driving circuit 20e.

[0085] In the data writing phase R1, the first transistor T1, the second transistor T2, and the third transistor T3 are turned on, and the other transistors are turned off. The voltage of the data line data is written to the third node Q through the first node A and the second node B, and the third transistor T3 performs threshold capture on the first transistor T1.

[0086] The time when the data signal connected to the data line data jumps occurs after the data writing stage R1, and the third transistor T3 is still in the on state after the data signal jumps high. In other words, the data signal jumps high and couples, so that the signal (Pscan) of the first level line VGH jumps high at the moment R2, and because the first level line VGH and the first node A and the second node B of the pixel circuit 10 generate coupling capacitance, the first node A and the second node B are pulled high, and then the third node Q is charged with more charge.

[0087] It can be understood that the conduction time of the third transistor T3 includes a continuous first time, a second time and a third time, the first time is before the data writing stage R1, the second time is in the data writing stage R1, and the third time is after the data writing stage. The signal of the first level line VGH is coupled and pulled high in the stage corresponding to the third time.

[0088] It should be noted that Figure 4 The recovery time after Pscan is pulled high is only an example. The recovery time of the first level line VGH can be determined according to the area of ​​the auxiliary wiring vg2. The larger the area of ​​the auxiliary wiring vg2, the shorter the signal recovery time of the first level line VGH, and the shorter the time when the first node A and the second node B are pulled high. That is, the faster the signal of the first level line VGH that is pulled high drops, the faster the voltage of the first node A and the second node B that are pulled high drops, thereby reducing the overcharge charge.

[0089] Optionally, in some embodiments, the moment when the signal of the first level line VGH is pulled up by the data signal high jump coupling to be fully restored is the restoration moment, and the restoration moment is before the turning-off moment of the third transistor T3.

[0090] Please combine Figures 1 to 4 , a display panel 100 provided in an embodiment of the present application includes a first driving circuit 20 a, a first level line VGH and a pixel circuit 10 .

[0091] The first level line VGH includes a signal wiring vg1 and an auxiliary wiring vg2 . The signal wiring vg1 is connected to the input electrode of the first thin film transistor M1 , and the auxiliary wiring vg2 is connected to the signal wiring vg1 .

[0092] The display panel 100 of the embodiment of the present application reduces the impedance of the first level line VGH by adding an auxiliary wiring vg2; therefore, after the data writing stage, the signal connected to the first level line VGH is pulled high as the data signal jumps high. Since the impedance of the first level line VGH is reduced, the time for the signal of the first level line VGH to return to normal can be accelerated, thereby reducing the risk of dark lines caused by overcharging of the third node Q.

[0093] Please refer to Figure 5 The display panel 100 includes a substrate 11, a circuit structure layer 12 and a display element EL. The circuit structure layer 12 is disposed on the substrate 11, and the display element EL is disposed on a side of the circuit structure layer 12 away from the substrate 11.

[0094] The circuit structure layer 12 includes a pixel circuit 10 and a first driving circuit 20 a to a fifth driving circuit 20 e. The display element EL is connected to the pixel circuit 10.

[0095] The circuit structure layer 12 includes a light shielding layer Ls, a buffer layer buf, a first active layer py1, a first insulating layer jy1, a first metal layer js1, a second insulating layer jy2, a second metal layer js2, a third insulating layer jy3, a second active layer py2, a fourth insulating layer jy4, a third metal layer js3, a fifth insulating layer jy5, a fourth metal layer js4, a sixth insulating layer jy6, a fifth metal layer js5, a seventh insulating layer jy7, a sixth metal layer js6 and an eighth insulating layer jy8, which are arranged in sequence. The display element EL includes an anode y1, a light emitting layer y2 and a cathode y3.

[0096] Optionally, in some embodiments of the present application, the signal trace vg1 is formed in the fifth metal layer js5, and the auxiliary trace vg2 is formed in the sixth metal layer js6. The pixel circuit 10 and the first to fifth driving circuits 20a to 20e are formed between the first active layer py1 and the sixth insulating layer jy6.

[0097] It should be noted that the auxiliary routing vg2 is arranged above the first driving circuit 20a to the fifth driving circuit 20e to avoid the auxiliary routing vg2 being connected thereto and to allow the auxiliary routing vg2 to have more layout space; in addition, the auxiliary routing vg2 is arranged on the sixth metal layer js6 which is farthest from the substrate 11, which can increase the distance between the auxiliary routing vg2 and other signal lines in the thickness direction, thereby reducing the risk of interfering with other signal lines.

[0098] Optionally, the first metal layer js1 to the sixth metal layer js6 can be formed using a metal element selected from chromium, copper, aluminum, gold, silver, zinc, molybdenum, tantalum, titanium, tungsten, manganese, nickel, iron, cobalt, an alloy containing any of the above metal elements as a component, or an alloy combining any of the above metal elements. In addition, the first metal layer js1 to the sixth metal layer js6 can have a single-layer structure or a stacked structure of two or more layers.

[0099] The materials of the first active layer py1 and the second active layer py2 may include single crystal silicon, polycrystalline silicon or oxide semiconductor. The materials of the first active layer py1 and the second active layer py2 are different, but not limited thereto, for example, the materials of the two may be the same.

[0100] Optionally, in some embodiments of the present application, the signal wiring vg1 and the auxiliary wiring vg2 are arranged in different layers in the thickness direction of the display panel 100. The auxiliary wiring vg2 is located on the side of the signal wiring vg1 away from the substrate; the auxiliary wiring vg2 at least covers at least one of the first driving circuit 20a, the second driving circuit 20b, the third driving circuit 20c, the fourth driving circuit 20d and the fifth driving circuit 20e.

[0101] It should be noted that as long as the first to fifth driving circuits 20a to 20e are not short-circuited with the auxiliary wiring vg2, in some embodiments, the thin film transistors of the first to fifth driving circuits 20a to 20e are arranged in different layers from the auxiliary wiring vg2, for example, the auxiliary wiring vg2 is arranged above the film layer where all the thin film transistors are located.

[0102] Secondly, it can be understood that the larger the coverage of the auxiliary wiring vg2, the lower the impedance of the first level line VGH, and the better the effect of improving the dark pattern. Therefore, the coverage of the auxiliary wiring vg2 can be adjusted according to actual needs. For example, the auxiliary wiring vg2 can be set in the area of ​​any one of the first drive circuit 20a to the fifth drive circuit 20e; it can also be set in the area of ​​any two of the first drive circuit 20a to the fifth drive circuit 20e; it can also be set in the area of ​​any three or four of the first drive circuit 20a to the fifth drive circuit 20e; or the auxiliary wiring vg2 can be set in the area of ​​the first drive circuit 20a to the fifth drive circuit 20e.

[0103] Optionally, in some embodiments of the present application, the display panel 100 further includes a clock signal line CK, and in a plan view of the display panel 100 , the auxiliary wiring vg2 is located outside the clock signal line CK.

[0104] It is understandable that the clock signal line CK is arranged in the circuit structure layer 12. The auxiliary line vg2 is arranged outside the clock signal line CK to avoid the auxiliary line vg2 and the clock signal line CK overlapping to generate parasitic capacitance, which will increase power consumption. Therefore, in some embodiments of the present application, the auxiliary line vg2 is arranged outside the clock signal line CK, which reduces the risk of generating parasitic capacitance, thereby reducing the risk of increased power consumption.

[0105] Please refer to Figure 6 and Figure 7 In some embodiments of the present application, the auxiliary trace vg2 includes a first auxiliary portion f1 , and in a plan view of the display panel 100 , the first auxiliary portion f1 covers the first thin film transistor M1 and the second thin film transistor M2 .

[0106] It can be understood that the first thin film transistor M1 and the second thin film transistor M2 are arranged adjacent to each other, and the layout area of ​​any one of them in the plan view is much larger than the area of ​​the third thin film transistor M3 to the eighth thin film transistor M8. Therefore, a first auxiliary part f1 with a larger area can be arranged in the area where the first thin film transistor M1 and the second thin film transistor M2 are located, and the first auxiliary part f1 is arranged directly above the first thin film transistor M1 and the second thin film transistor M2, which can reduce the risk of the first auxiliary part f1 coupling with other signal lines.

[0107] Secondly, when the first thin film transistor M1 is turned on, the high level signal of the first level line VGH is connected. At this time, the first auxiliary part f1 is also connected to the same high level signal, and the second thin film transistor M2 is turned off. Therefore, the first auxiliary part f1 has almost no interference with the first thin film transistor M1 and the second thin film transistor M2; therefore, the first auxiliary part f1 at least covers the first thin film transistor M1 and the second thin film transistor M2 to reduce the interference with the first driving circuit 20a.

[0108] Optionally, the first auxiliary portion f1 extends along the second direction F2 and covers a plurality of first thin film transistors M1 and second thin film transistors M2 of the first driving circuit 20a to increase the area of ​​the auxiliary wiring vg2 and further reduce the impedance of the first level line VGH.

[0109] Optionally, in some embodiments, the input electrode of the second thin film transistor M2 includes a first input bus s1 and a plurality of first input branch lines s2, the first input bus s1 extends along the second direction F2, the first input branch lines s2 extend along the first direction F1, and the plurality of first input branch lines s2 are arranged at intervals along the second direction F2 and connected to the first input bus s1. The output electrode of the second thin film transistor M2 includes a first output bus h1 and a plurality of first output branch lines h2, the first output bus h1 extends along the second direction F2, the first output branch lines h2 extend along the first direction F1, and the plurality of first output branch lines h2 are arranged at intervals along the second direction F2. The first direction F1 and the second direction F2 intersect.

[0110] The first input branch lines s2 and the first output branch lines h2 are alternately arranged along the second direction F2, and the first input bus s1 and the first output bus are separated by the first input branch lines s2 and the first output branch lines h2.

[0111] The input electrode sr2 of the first thin film transistor M1 is extended along the first direction F1 , and the first output branch line h2 of the second thin film transistor M2 is multiplexed as the output electrode of the first thin film transistor M1 .

[0112] Optionally, in some embodiments of the present application, the first auxiliary part f1 includes a first sub-line f11, a second sub-line f12 and a third sub-line f13, the first sub-line f11 is connected to the signal trace vg1 through a via k1, and the second sub-line f12 is connected to the first sub-line f11 and the third sub-line f13.

[0113] In a plan view of the display panel 100, the clock signal line CK, the signal routing line vg1, the first sub-line f11 and the third sub-line f13 are extended along the second direction F2, and the second sub-line f12 is extended along the first direction F1 intersecting the second direction F2. A plurality of first driving circuits 20a are arranged along the second direction F2. The first thin film transistors M1 and the second thin film transistors M2 are arranged along the second direction F2, and the second sub-line f12 and the third sub-line f13 are located on a side of the first sub-line f11 away from the clock signal line CK.

[0114] The first sub-line f11 overlaps with the signal wiring vg1 , the second sub-line f12 is located between two adjacent first driving circuits 20 a , and the third sub-line f13 covers the first thin film transistor M1 and the second thin film transistor M2 .

[0115] It can be understood that the first sub-line f11 is connected to the signal line vg1 through multiple vias k1, further reducing the impedance of the first level line VGH. Secondly, the second sub-line f12 and the third sub-line f13 are kept away from the clock signal line CK, which not only avoids the vertical parasitic capacitance with the clock signal line CK, but also reduces the risk of lateral parasitic capacitance with the clock signal line CK, further reducing power consumption.

[0116] Optionally, the third sub-line f13 extends along the second direction F2 and covers a plurality of first thin film transistors M1 and second thin film transistors M2 of the first driving circuit 20a, so as to increase the area of ​​the auxiliary wiring vg2 and further reduce the impedance of the first level line VGH.

[0117] Optionally, in some embodiments, a third sub-line f13 can be used to cover the entire area of ​​the first thin film transistor M1 and the second thin film transistor M2, which can increase the area of ​​the auxiliary wiring vg2 and thereby reduce the impedance of the first level line VGH; or a plurality of third sub-lines f13 can be arranged at intervals and cover the areas of the first thin film transistor M1 and the second thin film transistor M2, which can reduce interference with the first thin film transistor M1 and the second thin film transistor M2.

[0118] Optionally, in some embodiments, all the third sub-lines f13 are arranged between the first input bus s1 and the first output bus h1 to further reduce interference to other signal lines.

[0119] Optionally, in some embodiments of the present application, in a plan view of the display panel 100, in a first direction F1, a distance from the first sub-line f11 to the nearest clock signal line CK is a first distance L1, and a distance from the first sub-line f11 to the nearest third sub-line f13 is a second distance L2, and the second distance L2 is greater than the first distance L1.

[0120] It can be understood that in the area of ​​the first driving circuit 20a, the second distance L2 is greater than the first distance L1, so that the third sub-line f13 is far away from the clock signal line CK, thereby reducing the interference of the third sub-line f13 on the clock signal line CK, that is, reducing the risk of forming parasitic capacitance.

[0121] Optionally, in some embodiments of the present application, in a plan view of the display panel 100 , a total area of ​​the third sub-lines f13 is greater than a total area of ​​the first sub-lines f11 .

[0122] It can be understood that since the third sub-line f13 is far away from the clock signal line CK, the total area of ​​the third sub-line f13 is set to be larger, which can not only reduce the risk of forming parasitic capacitance with the clock signal line CK, but also increase the area of ​​the auxiliary routing vg2, and further reduce the impedance of the first level line VGH.

[0123] Optionally, in some embodiments of the present application, in a plan view of the display panel 100, in the first direction F1, the first clock signal line CK1 is located on a side of the second clock signal line CK2 away from the first sub-line f11, and the third sub-line f13 and the first sub-line f11 are interposed with the third thin film transistor M3, the fourth thin film transistor M4, the fifth thin film transistor M5, the sixth thin film transistor M6, the seventh thin film transistor M7, the eighth thin film transistor and the second capacitor C2.

[0124] It can be understood that by arranging the third thin film transistor M3, the fourth thin film transistor M4, the fifth thin film transistor M5, the sixth thin film transistor M6, the seventh thin film transistor M7, the eighth thin film transistor and the second capacitor C2 between the second clock signal line CK2 and the first thin film transistor M1, the distance between the first thin film transistor M1 and the second thin film transistor M2 and the second clock signal line CK2 can be increased respectively. Based on the fact that the third sub-line f13 is arranged above the area of ​​the first thin film transistor M1 and the second thin film transistor M2, the risk of parasitic capacitance generated by the third sub-line f13 and the second clock signal line CK2 can be reduced.

[0125] Please refer to Figures 8 to 10 , Figure 8 FIG. 2 shows an equivalent circuit diagram of an exemplary fourth driving circuit 20 d of the present application. Fig. 9 FIG. 2 is a schematic plan view of an exemplary fourth driving circuit 20 d of the present application. Fig.10 It shows Fig. 9 FIG. 2 is a plan view of a single fourth driving circuit 20 d.

[0136] It should be noted that the fourth driving circuit 20d controls the on and off of the first control module 10c and the second control module 10d of the pixel circuit 10 by controlling the on and off of the ninth thin film transistor M9 and the tenth thin film transistor M10. That is, the output electrodes of the ninth thin film transistor M9 and the tenth thin film transistor M10 are connected and serve as the output terminal EM of the fourth driving circuit 20d.

[0137] exist Figure 8 In the embodiment, the ninth thin film transistor M9 to the twenty-first thin film transistor M21 are all p-type transistors, and in response, the third level line VGH1 is configured to access a high level signal, and the first control module 10c and the second control module 10d are set to access the high level signal to be turned off. The fourth level line VGL1 is configured to access a low level signal. However, this is only exemplary, and at least one of the ninth thin film transistor M9 to the twenty-first thin film transistor M21 can also be an n-type transistor. And when the transistor is replaced with an n-type, the corresponding control signal also changes accordingly.

[0138] Optionally, in some embodiments of the present application, the auxiliary wiring vg2 includes a second auxiliary portion f2. In a plan view of the display panel 100, the second auxiliary portion f2 covers the ninth thin film transistor M9 and the tenth thin film transistor M10.

[0139] It can be understood that the ninth thin film transistor M9 and the tenth thin film transistor M10 are arranged adjacent to each other, and the layout area of ​​either of them in the plan view is much larger than the area of ​​the eleventh to twenty-first thin film transistors M11 to M21. Therefore, a second auxiliary part f2 with a larger area can be set in the area where the ninth thin film transistor M9 and the tenth thin film transistor M10 are located, and the second auxiliary part f2 is set directly above the ninth thin film transistor M9 and the tenth thin film transistor M10, which can reduce the risk of the second auxiliary part f2 coupling other signal lines.

[0140] Optionally, the second auxiliary portion f2 extends along the second direction F2 and covers the ninth thin film transistor M9 and the tenth thin film transistor M10 of the fourth driving circuit 20d to increase the area of ​​the second auxiliary portion f2 and further reduce the impedance of the first level line VGH.

[0141] Optionally, in some embodiments, the input electrode of the ninth thin film transistor M9 includes a plurality of third input branch lines s3, the third input branch lines s3 extend along the first direction F1, and the plurality of third input branch lines s3 are arranged at intervals along the second direction F2 and connected to the third level line VGH1. The output electrode of the ninth thin film transistor M9 includes a third output bus h3 and a plurality of third output branch lines h4, the third output bus h3 extends along the second direction F2, the third output branch lines h4 extend along the first direction F1, and the plurality of third output branch lines h4 are arranged at intervals along the second direction F2. The first direction F1 intersects with the second direction F2. Among them, the third input branch lines s3 and the third output branch lines h4 are alternately arranged along the second direction F2, and the third level line VGH1 and the third output bus h3 are spaced apart by the third input branch lines s3 and the third output branch lines h4.

[0142] The input electrode of the tenth thin film transistor M10 includes a plurality of fourth input branch lines s4 extending along the first direction F1 , and the plurality of fourth input branch lines s4 are arranged at intervals along the second direction F2 and connected to the fourth level line VGL1 .

[0143] The output electrode of the tenth thin film transistor M10 includes a fourth output bus h5 and a plurality of fourth output branch lines h6, the fourth output bus h5 extends along the second direction F2 and is connected to the third output bus h3. The fourth output branch line h6 extends along the first direction F1, and the plurality of fourth output branch lines h6 are arranged at intervals along the second direction F2. The first direction F1 intersects the second direction F2. Among them, the fourth input branch line s4 and the fourth output branch line h6 are alternately arranged along the second direction F2, and the ninth thin film transistor M9 and the tenth thin film transistor M10 are spaced between the third level line VGH1 and the fourth level line VGL1.

[0144] Optionally, in some embodiments of the present application, in a plan view of the display panel 100, the third level line VGH1, the fourth level line VGL1 and the second auxiliary part f2 extend along the second direction F2, the ninth thin film transistor M9 and the tenth thin film transistor M10 are arranged along the second direction F2, and the third level line VGH1 and the second auxiliary part f2 are set to be connected to the same voltage.

[0145] In the first direction F1 intersecting with the second direction F2, the ninth thin film transistor M9, the tenth thin film transistor M10 and the second auxiliary part f2 are located between the third level line VGH1 and the fourth level line VGL1, and the distance L3 from the third level line VGH1 to the second auxiliary part f2 is smaller than the distance L4 from the second auxiliary part f2 to the fourth level line VGL1.

[0146] It is understandable that, since the third level line VGH1 and the second auxiliary part f2 are connected to the same voltage, the risk of the second auxiliary part f2 interfering with other signal lines can be reduced by placing the second auxiliary part f2 closer to the third level line VGH1 .

[0163] Optionally, in some embodiments of the present application, the auxiliary wiring vg2 includes a third auxiliary portion f3. In a plan view of the display panel 100, the third auxiliary portion f3 covers the twenty-second thin film transistor M22 and the twenty-third thin film transistor M23.

[0164] It can be understood that the twenty-second thin film transistor M22 and the twenty-third thin film transistor M23 are arranged adjacent to each other, and the layout area of ​​either of them in the plan view is much larger than the area of ​​the twenty-fourth thin film transistor M24 to the thirty-fourth thin film transistor M34.

[0165] Optionally, the third auxiliary portion f3 extends along the second direction F2 and covers the twenty-second thin film transistors M22 and the twenty-third thin film transistors M23 of the fifth driving circuit 20e to increase the area of ​​the third auxiliary portion f3 and further reduce the impedance of the first level line VGH.

[0168] It is understandable that, since the fifth level line VGH2 and the third auxiliary part f3 are connected to the same voltage, the third auxiliary part f3 is closer to the fifth level line VGH2, which can reduce the risk of the third auxiliary part f3 interfering with other signal lines.

[0169] Optionally, in some embodiments of the present application, in a plan view of the display panel 100, in the first direction F1, the fifth clock signal line CK5 and the sixth clock signal line CK6 are adjacent to each other, and the fifth clock signal line CK5 and the third auxiliary portion f3 are interposed with the twenty-fourth thin film transistor M24, the twenty-fifth thin film transistor M25, the twenty-sixth thin film transistor M26, the twenty-seventh thin film transistor M27, the twenty-eighth thin film transistor M28, the twenty-ninth thin film transistor M29, the thirtieth thin film transistor M30, the thirty-first thin film transistor M31, the thirty-second thin film transistor M32, the thirty-third thin film transistor M33, the thirty-fourth thin film transistor M34, the sixth capacitor C6, the seventh capacitor C7 and the eighth capacitor C8.

[0170] It can be understood that by arranging the twenty-fourth thin film transistor M24, the twenty-fifth thin film transistor M25, the twenty-sixth thin film transistor M26, the twenty-seventh thin film transistor M27, the twenty-eighth thin film transistor M28, the twenty-ninth thin film transistor M29, the thirtieth thin film transistor M30, the thirty-first thin film transistor M31, the thirty-second thin film transistor M32, the thirty-third thin film transistor M33, the thirty-fourth thin film transistor M34, the sixth capacitor C6, the seventh capacitor C7 and the eighth capacitor C8 between the fifth clock signal line CK5 and the twenty-second thin film transistor M22, the distance between the twenty-second thin film transistor M22 and the twenty-third thin film transistor M23 and the fifth clock signal line CK5 can be increased respectively, and based on the third auxiliary part f3 being arranged above the area of ​​the twenty-second thin film transistor M22 and the twenty-third thin film transistor M23, the risk of parasitic capacitance generated by the third auxiliary part f3 and the fifth clock signal line CK5 can be reduced.

[0171] Optionally, in some embodiments of the present application, the circuit structure of the fifth driving circuit 20e may be the same as the circuit structure of the fourth driving circuit 20d, for example Fig.13 and Fig.10 Same, but not limited to this.

[0172] Optionally, in some embodiments of the present application, the auxiliary wiring vg2 further includes a first connection portion f4 and a second connection portion f5, and the auxiliary wiring vg2 further includes a second auxiliary portion f2 and a third auxiliary portion f3. In a plan view of the display panel 100, the second auxiliary portion f2 covers the ninth thin film transistor M9 and the tenth thin film transistor M10 in the fourth drive circuit 20d, and the third auxiliary portion f3 covers the twenty-second thin film transistor M22 and the twenty-third thin film transistor M23 in the fifth drive circuit 20e. The first connection portion f4 connects the second auxiliary portion f2 and the third auxiliary portion f3, and the second connection portion f5 connects the third auxiliary portion f3 and the first auxiliary portion f1.

[0173] That is, the auxiliary wiring vg2 is arranged in the area of ​​the first driving circuit 20a, the fourth driving circuit 20d and the fifth driving circuit 20e, and is connected into one through the first connecting portion f4 and the second connecting portion f5 to increase the area of ​​the auxiliary wiring vg2, thereby greatly reducing the impedance of the first level line VGH.

[0174] Optionally, in some embodiments, the first level line VGH, the third level line VGH1 and the fifth level line VGH2 can be connected and connected to the same signal, but not limited to this, for example, the three can also be connected to the level signal independently. The second level line VGL, the fourth level line VGL1 and the sixth level line VGL2 can be connected and connected to the same signal, but not limited to this, for example, the three can also be connected to the level signal independently.

[0175] The display panel of the embodiment of the present application reduces the impedance of the first level line by adding auxiliary wiring; therefore, after the first thin film transistor is turned off, the signal connected to the first level line is pulled high as the data signal jumps high. Since the impedance of the first level line is reduced, the time for the signal of the first level line to return to normal can be accelerated, thereby reducing the risk of dark lines caused by overcharging of the Q node.

Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
