[0192] A first electrode of the second capacitor C2 is connected to the control electrode of the ninth transistor T9, and a second electrode of the second capacitor C2 is connected to the second electrode of the ninth transistor T9;

[0193] The first voltage stabilizing module 221 includes a sixteenth transistor T16, a first electrode of the sixteenth transistor T16 is connected to the fourth node N4, a second electrode of the sixteenth transistor T16 is connected to the first node N1, and a control electrode of the sixteenth transistor T16 is connected to the first power signal terminal VGA; the setting of the sixteenth transistor T16 can prevent current backflow and improve the stability of the circuit.

[0194] The second voltage stabilizing module 222 includes a seventeenth transistor T17, a first electrode of the seventeenth transistor T17 being connected to the fifth node N5, and a second electrode of the seventeenth transistor T17 being connected to the first node N1. The seventeenth transistor T17 can prevent current backflow and improve circuit stability.

[0195] It is understandable that the first voltage stabilizing module and the second voltage stabilizing module can also be configured as other voltage stabilizing circuit structures. The first capacitor C1 and the second capacitor C2 can be selected to have a capacity of 20 farad to 30 farad (i.e., 20f to 30f).

[0200] Considering that there is no load on the signal line of the first output sub-circuit 30, which may easily lead to instability of the cascade signal, a capacitor with a large capacitance is coupled to the cascade output terminal OT.

[0201] For example, as shown in FIG2 , in some embodiments, the first output sub-circuit 30 further includes a fourth capacitor C4 , a first end of the fourth capacitor C4 is connected to the cascade output terminal OT, and a second end of the fourth capacitor C4 is connected to the first power signal terminal VGA.

Alternatively, the fourth capacitor C4 is a capacitor of 100f. This fourth capacitor C4 can make the cascade signal output by the first output sub-circuit 30 more stable.

[0312] When it is determined to adopt the partial refresh mode, a second signal is input to the control signal terminal VFE of the plurality of shift register units (e.g., G1, G2, G3, G4, G5, G6, G7, G8 in FIG4 ), so that some of the shift register units (e.g., G1, G2, G3, G4, G5, G6, G7, G8 in FIG4 ) sequentially output gate scan signals, and the remaining shift register units output invalid scan signals.

[0317] In S200, when it is determined to adopt the partition refresh mode, a second signal is output to the control signal end of the multiple shift register units (for example, G1, G2, G3, G4, G5, G6, G7, and G8 in Figure 4), so that some of the multiple shift register units (for example, G1, G2, G3, G4, G5, G6, G7, and G8 in Figure 4) output gate scan signals in sequence, and the remaining shift register units output invalid scan signals to drive some of the scan lines.

The second level is the level of an inactive gate scan signal. The fixed signal portion having a clock signal is input to some of the shift register units, and the fixed signal portion having the second level is input to the remaining shift register units. For example, as shown in FIG7 , the second signal includes a fixed signal portion V2 having a clock signal and a fixed signal portion V3 having a second level. This second signal inputs a valid signal to the shift register units G1, G2, G3, and G4, causing the shift register units G1, G2, G3, and G4 to sequentially output valid gate scan signals, driving the scan lines row by row; and inputs an invalid signal to the shift register units G5, G6, G7, and G8, causing the shift register units G5, G6, G7, and G8 to output invalid scan signals, thereby driving some of the scan lines. For example, the fixed signal portion having a clock signal can be a clock signal that alternates between a first level and a second level.

[0319] Optionally, the gate scanning signal is a high-level signal and the invalid scanning signal is a low-level signal, or the gate scanning signal is a low-level signal and the invalid scanning signal is a high-level signal, which is not limited here.

The first output signal terminal OT outputs a low signal, and the second output signal terminal OUT outputs a low signal.

[0335] As shown in Figure 6, in some embodiments, the valid gate scan signal output by the next shift register unit is 1H later than that of the previous shift register unit, where 1H = 2.73μs. The pulse width of the input signal in is R2 = 1.73μs. The clock signal ck1 output by the first clock signal line CK1 has a cycle of 2H, its high-level pulse width is Q1 + Q2, and its low-level pulse width is R1, R1 = 2.13μs, Q1 = 1.66μs, and Q2 = 1.67μs. The clock signal ck2 output by the second clock signal line CK2 has a cycle of 2H, its high-level pulse width is also Q1 + Q2, and its low-level pulse width is also R1. The clock signal ck3 output by the third clock signal line CK3 has a cycle of 2H. The clock signal ck4 output by the fourth clock signal line CK4 is a clock signal that alternates between a 1H high-level pulse width and a 1H low-level signal. The clock signal in ck4, which alternates with the low-level signal, has a high-level pulse width of R2 = 1.73s. The low-level pulse widths connected to the adjacent low-level signals are both Q3 = 0.5μs. The first clock signal cka at the first clock signal terminal CKA is a clock signal formed by alternating between ck1 and ck2. The second clock signal ckb at the second clock signal terminal CKB is a clock signal formed by alternating between ck1 and ck2. The third clock signal ckd at the third clock signal terminal CKD is a clock signal formed by alternating between ck3 and ck4. vfe1 is consistent with ck3, and vfe2 is consistent with ck4. For details of ck1, ck2, ck3, ck4, cka, ckb, ckd, vfe1, and vfe2, see Figure 6.

[0336] For example, in a display panel with 1024 rows of pixels, there are 512 shift register units, each of which controls two rows of pixels. Eight adjacent shift register units form a group, for a total of 64 groups. The control signal terminals VFE of the shift register units in the odd-numbered groups are coupled to the first control sub-signal line VFE1, and the control signal terminals VFE of the shift register units in the even-numbered groups are coupled to the second control sub-signal line VFE2. When the first control sub-signal line VFE1 and the second control sub-signal line VFE2 are controlled to output the second signal, the shift register units in the first to thirty-second groups output valid gate scan signals in each of the 120 frames, and the shift register units in the thirty-third to sixty-fourth groups output valid gate scan signals every other frame in the 120 frames. This allows the display panel's first 512 rows of pixels to be controlled at 120 Hz, while the last 512 rows of pixels to be controlled at 60 Hz, thereby achieving partitioned refresh. Of course, the first control sub-signal line VFE1 and the second control sub-signal line VFE2 may also be controlled to output the second signal so that any group outputs a valid gate scan signal or an invalid gate scan signal in any frame to achieve partitioned refresh of the display panel.
