[0062] The present disclosure will now be described in more detail with reference to the following examples. It should be noted that the following description of some of the embodiments presented herein is for illustration and description purposes only. It is not intended to be exhaustive or limited to the precise form disclosed.
[0063] The relevant scanning circuit in the relevant display device usually uses polysilicon as the semiconductor material to manufacture the active layer of the transistor. However, polysilicon transistors are prone to leakage current. The inventors of the present disclosure have found that transistors using metal oxide materials as the material for manufacturing the active layer have better performance and have negligible leakage current. In addition, the inventors of the present disclosure have found that, surprisingly and unexpectedly, the substrate bias effect can be used to significantly improve the performance of metal oxide transistors.
[0064] The substrate bias effect refers to the influence of the substrate voltage between the source and the drain on the threshold voltage (Vth) of the transistor. When the substrate voltage is positive, Vth will be caused to shift toward the positive bias; conversely, when the substrate voltage is negative, Vth will be caused to shift toward the negative bias. The inventors of the present disclosure have found that the substrate bias effect can be used to implement a positive bias of Vth in a transistor, thereby ensuring that the transistor can be correctly turned on or off. Specifically, the substrate voltage of the transistor can be set to a positive value, which will cause Vth to shift toward the positive bias. This method ensures that the transistor operates within the correct voltage range and avoids unnecessary errors.

For a p-type transistor, a valid control signal (e.g., a turn-on control signal) is a low voltage signal, while an invalid control signal (e.g., a cut-off control signal) is a high voltage signal.

In some embodiments, the gate-on voltage of the first to tenth transistors T1 to T10 may be set to a high level, and the gate-off voltage may be set to a low level.
[0086] In an alternative embodiment, each of the first to tenth transistors T1 to T10 may be formed of a p-type transistor. In some embodiments, the gate-on voltage of the first to tenth transistors T1 to T10 may be set to a low level, and the gate-off voltage may be set to a high level.

[0088] In some embodiments, during the first phase p1, the first clock signal CK is provided to the second input terminal TM2. The first transistor T1 and the third transistor T3 are turned on. In addition, during the first phase p1, the second clock signal CB is not provided to the third input terminal TM3, and the fourth transistor T4 and the seventh transistor T7 are turned off.
[0089] In some embodiments, during the first phase p1, the start signal STV to be provided to the first input terminal TM1 or the output signal Outp from the output terminal of the previous scanning unit has a high level, and a high voltage (e.g., the voltage of the second power signal VGH) may be applied to the first node N1. When the first node N1 is set to a high voltage, the second transistor T2, the eighth transistor T8, and the tenth transistor T10 are turned on.
[0090] In some embodiments, when the second transistor T2 is turned on, the voltage of the first clock signal CK is provided to the second node N2. The fifth transistor T5 and the sixth transistor T6 are turned on.
[0091] In some embodiments, when the third transistor T3 is turned on, the voltage of the second power signal VGH is provided to the second node N2. The fifth transistor T5 and the sixth transistor T6 are turned on.

[0094] In some embodiments, during the second phase p2, the supply of the first clock signal CK to the second input terminal TM2 is interrupted. The first transistor T1 and the third transistor T3 are turned off. The first node N1 maintains the voltage of the previous phase. Since the first node N1 is maintained in a high voltage state, the second transistor T2, the eighth transistor T8 and the tenth transistor T10 remain turned on. When the eighth transistor T8 remains turned on, the voltage of the first power supply signal VGL is provided to the fourth node N4. Since the fourth node N4 remains in a low voltage state, the ninth transistor T9 remains turned off.
[0095] In some embodiments, during the second phase p2, the second clock signal CB is provided to the third input terminal TM3. The fourth transistor T4 and the seventh transistor T7 are turned on by the second clock signal CB provided to the third input terminal TM3. When the seventh transistor T7 is turned on, the fourth node N4 and the third node N3 are electrically coupled to each other. The third node N3 is set to a low voltage.

[0097] In some embodiments, during the third phase p3, the start signal STV or the output signal Outp from the output terminal of the previous scan unit is provided to the first input terminal TM1, and the first clock signal CK is provided to the second input terminal TM2. When the first clock signal CK is provided to the second input terminal TM2, the first transistor T1 and the third transistor T3 are turned on.
[0098] In some embodiments, when the first transistor T1 is turned on, the first input terminal TM1 is electrically coupled to the first node N1. The first node N1 is set to a low voltage by a start signal STV provided to the first input terminal TM1 or an output signal Outp from an output terminal of a previous scanning unit. When the first node N1 is set to a low voltage, the second transistor T2, the eighth transistor T8, and the tenth transistor T10 are turned off.
[0099] In some embodiments, when the sixth transistor T6 is turned on, the third input terminal TM3 and the third node N3 are electrically coupled to each other. Since the second clock signal CB is not provided to the third input terminal TM3 during the third phase p3, the third node N3 is maintained at a low voltage. Since the seventh transistor T7 remains turned off, the voltage of the third node N3 does not affect the voltage of the fourth node N4. The first capacitor C1 is configured to store a voltage corresponding to the turn-on level of the sixth transistor T6.
[0100] In some embodiments, during the fourth phase p4, the second clock signal CB may be provided to the third input terminal TM3. When the second clock signal CB is provided to the third input terminal TM3, the seventh transistor T7 is turned on.
[0101] In some embodiments, when the seventh transistor T7 is turned on, the fourth node N4 and the third node N3 are electrically coupled to each other. The high voltage of the second clock signal CB provided to the third input terminal TM3 is provided to the third node N3 and the fourth node N4 via the sixth transistor T6 that remains turned on. When the high voltage is provided to the fourth node N4, the ninth transistor T9 is turned on.
[0102] In some embodiments, when the ninth transistor T9 is turned on, the voltage of the first power signal VGL is provided to the output terminal TM4. The voltage of the first power signal VGL provided to the output terminal TM4 is provided to the n-th gate line as a gate driving signal.
[0103] In some embodiments, during the fifth stage p5, the supply of the second clock signal CB to the third input terminal TM3 is interrupted. When the supply of the second clock signal CB is interrupted, the seventh transistor T7 is turned off. The fourth node N4 is stably maintained at a high voltage through the second capacitor C2. The ninth transistor T9 remains turned on, and the voltage of the first power supply signal VGL is provided to the nth level gate line as a gate drive signal.
[0104] The supply of the second clock signal CB is interrupted during the fifth phase p5 , so the fourth transistor T4 remains turned off, and thus the voltage of the second clock signal CB does not affect the voltage of the first node N1 .
