Drop-down unit 13 can have second switch 131, the first end 133 of second switch 131 is coupled to gate lines G (n) via the first transmission path 50 equally, second end 135 is coupled to cold end VSS, control end 137 is coupled to the second reference signal end, in order to receive the second reference signal RC2, the voltage level of pulldown gate line G (n) according to this, wherein, the first end 133 of second switch 131 also can connect the second end 115 of the first switch 111.With the situation of practical operation, when second switch 131 is N-type transistor, when the control end 137 of second switch 131 receives the second reference signal RC2 of high voltage level, second switch 131 conducting, the voltage level of gate lines G (n) is pulled down to the voltage level of low-voltage end VSS.
Pull-up unit 11 and drop-down unit 13 are controlled by the first reference signal RC1 and the second reference signal RC2 respectively, determine the voltage level of gate lines G (n).First reference signal RC1 can be the voltage level of gate lines G (n-2), and the second reference signal RC2 can be the voltage level of gate lines G (n+4).
Control module 15 can have gauge tap 151, and the first end 153 of gauge tap 151 is coupled to gate lines G (n) via the first transmission path 50.In other words, the first end 153 of gauge tap 151 can connect the first end 133 of the second end 115 of the first switch 111, second switch 131, and connects Voltage stabilizing module 30 via the second transmission path 70.The control end 157 of gauge tap 151 is coupled to sweep signal end ST, in order to foundation sweep signal, export the gate driver circuit of gate driving control signal to other, such as be coupled to gate driver circuit GOAn+2 with the second end 155 of gauge tap 151, first reference signal of gate driver circuit GOAn+2 is provided.
Voltage stabilizing module 30 can have multiple stabilized switch, stabilized switch 31,32 as shown in Figure 2.With stabilized switch 31, the first end of stabilized switch 31 is coupled to gate lines G (n) via the second transmission path 70, second end of stabilized switch 31 is coupled to cold end VSS, and wherein, the second end of stabilized switch 31 also can connect the second end 135 of second switch 131.Stabilized switch 31 is coupled to voltage regulation signal end LC1, in order to according to voltage regulation signal, stablizes the voltage level in gate lines G (n).Wherein, in multiple stabilized switch, the first end of stabilized switch 32 is coupled to gate lines G (n) via the second transmission path 70, second end of stabilized switch 32 is coupled to cold end VSS, wherein, the second end of stabilized switch 32 also can connect the second end 135 of second switch 131 and the second end of stabilized switch 31.Stabilized switch 32 is coupled to voltage regulation signal end LC2, in order to according to voltage regulation signal, stablizes the voltage level in gate lines G (n).In the present embodiment, stabilized switch 31 and stabilized switch 32 can carry out the voltage level on stable gate lines G (n) respectively according to the voltage regulation signal of voltage regulation signal end LC1 sequential different from voltage regulation signal end LC2, but and are not used to limit the present embodiment.In other embodiments, stabilized switch 31 and stabilized switch 32 can also carry out the voltage level on stable gate lines G (n) according to the voltage regulation signal of same voltage regulation signal end.
