[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application No. 202310720909.3 filed in China on June 16, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to the field of display technology, and in particular to a driving circuit, a driving method, and a display device. Background Art

[0004] In related technologies, when an OLED (organic light-emitting diode) display updates its screen, it is necessary to initialize and write pixel voltages to all rows of pixel circuits within one frame. However, in certain special screens (such as the AOD display screen (the AOD display screen is a screen that controls the partial lighting of the screen without lighting the entire mobile phone screen), static screens, or screens that are updated less frequently), the pixel voltages of most pixel circuits on the entire screen do not need to be updated. That is, most pixel circuits can be maintained at the original display brightness through low-leakage LTPO (low-temperature polycrystalline oxide) TFTs (thin-film transistors), and repeated refreshing of these pixel circuits results in a waste of power consumption.

[0457] 2. When GCK provides a low voltage signal, T19 is closed and T20 is opened. GCB provides a high voltage signal, T16 is closed and T23 is opened. At this time, the circuit is in the registered state. T21, T22, T23 and T11 form a latch circuit. The potential of N6 and the signal provided by NS (N) maintain the previous state unchanged.

[0458] 3.

[0463] If VCT provides a low voltage signal when TX1, TX2, TX3 and TX4 are turned on, N1 will be written to a low voltage, and the NAND gate is in the cut-off state, ensuring that NO(N) provides a low voltage signal, thereby achieving the low level maintenance of NO(N).

[0468] Afterwards, in the Nth stage driving signal providing phase, NS(N) outputs a high voltage signal.

[0469] When the potential of N1 is low voltage, T10 is turned off, T11 is turned on, the potential of N2 is high voltage, T15 is turned on, and NO(N) outputs a low voltage signal;

[0470] When the potential of N1 is high voltage, T10 is turned off, T11 is turned off, T12 and T13 are turned on, the potential of N2 is low voltage, T14 is turned on, and NO(N) outputs a high voltage signal;

[0471] After the Nth stage of driving signal supply, NS(N) outputs a low voltage signal.

[0472] When the potential of N1 is a low voltage signal, T10 is turned on, T11 is turned on, the potential of N2 is a high voltage, and NO(N) outputs a low voltage signal;

[0473] When the potential of N1 is a high voltage signal, T10 is turned on, T11 is turned off, the potential of N2 is a high voltage, and NO(N) outputs a low voltage signal.
