Level (that is, the output signal is off signal).
具体结合图2和图3所示,在第一阶段T1,第一控制端SET输出电平为高点平,而控制第一晶体管M1导通,使得上拉节点P的电位为第一电压端DIR1输出的高电平。进而与上拉节点P连接的第三晶体管M3、第四晶体管M4、第十五晶体管M15和第十六晶体管M16均导通,以使得第一下拉节点Q1和第二下拉节点Q2的电位为第三电压端V3输出的低电平,以及,使得扫描输出端Gout和级联输出端Gout_sub的输出信号为时钟信号端CK输出的电平。其中,由于第一下拉节点Q1和第二下拉节点Q2的电位均为低电平,故而,使得与两者连通的晶体管均为截止状态。Specifically as shown in Figure 2 and Figure 3, in the first stage T1, the output level of the first control terminal SET is high and flat, and the first transistor M1 is controlled to be turned on, so that the potential of the pull-up node P is the first voltage terminal High level of DIR1 output. Furthermore, the third transistor M3, the fourth transistor M4, the fifteenth transistor M15, and the sixteenth transistor M16 connected to the pull-up node P are all turned on, so that the potentials of the first pull-down node Q1 and the second pull-down node Q2 are The low level output by the third voltage terminal V3, and the output signal of the scan output terminal Gout and the cascade output terminal Gout_sub are at the level output by the clock signal terminal CK. Wherein, since the potentials of the first pull-down node Q1 and the second pull-down node Q2 are both at low level, the transistors connected to them are all in an off state.
在第二阶段T2,扫描输出模块500和级联输出模块600均响应于上拉节点P的电位,而控制时钟信号端CK分别与扫描输出端Gout和级联输出端Gout_sub之间接通,此时时钟信号端CK输出电平为高电平。In the second stage T2, both the scan output module 500 and the cascade output module 600 respond to the potential of the pull-up node P, and the control clock signal terminal CK is respectively connected to the scan output terminal Gout and the cascade output terminal Gout_sub, at this time The output level of the clock signal terminal CK is high level.
具体结合图2和图3所示,在第二阶段T2,此时电容C的一极板的电位为时钟信号端CK输出的高电平,故而,电容C将会将与其另一极板连接的上拉节点P的高电平,在第一阶段T1的基础上再次拉高。由于上拉节点P的电位保持为高电平,因而与上拉节点P连通的晶体管保持第一阶段T1的状态不变。以及,在第二阶段T2,时钟信号端CK输出电平为高电平,该高电平信号分别通过第十五晶体管M15和第十六晶体管M16,传输至扫描输出端Gout和级联输出端Gout_sub。Specifically as shown in Figure 2 and Figure 3, in the second stage T2, the potential of one plate of the capacitor C is the high level output by the clock signal terminal CK, so the capacitor C will be connected to the other plate The high level of the pull-up node P is pulled high again on the basis of the first stage T1. Since the potential of the pull-up node P remains high, the transistors connected to the pull-up node P keep the state of the first stage T1 unchanged. And, in the second stage T2, the output level of the clock signal terminal CK is high level, and the high level signal is transmitted to the scan output terminal Gout and the cascade output terminal through the fifteenth transistor M15 and the sixteenth transistor M16 respectively Gout_sub.
在第三阶段T3,输入模块100响应于第二控制端RESET的电位,而控制第二电压端DIR2与上拉节点P之间接通,上拉节点P的电位为第二电压端DIR2输出的低电平;其中,第一下拉生成模块401响应于第二信号端Clock2的电位,而控制第二信号端Clock2与第一下拉节点Q1之间接通;或者,第二下拉生成模块402响应于第一信号端Clock1的电位,而控制第一信号端Clock1与第二下拉节点Q2之间接通。此时,第一下拉节点Q1控制第一下拉控制模块301工作,或第二下拉节点Q2控制第二下拉控制模块302工作,使得上拉节点P与第三电压端V3之间接通、扫描输出端Gout与第四电压端V4之间接通和级联输出端Gout_sub与第三电压端V3之前接通。In the third stage T3, the input module 100 controls the connection between the second voltage terminal DIR2 and the pull-up node P in response to the potential of the second control terminal RESET, and the potential of the pull-up node P is the low voltage output by the second voltage terminal DIR2. level; wherein, the first pull-down generating module 401 controls the connection between the second signal terminal Clock2 and the first pull-down node Q1 in response to the potential of the second signal terminal Clock2; or, the second pull-down generating module 402 responds to The potential of the first signal terminal Clock1 controls the connection between the first signal terminal Clock1 and the second pull-down node Q2. At this time, the first pull-down node Q1 controls the first pull-down control module 301 to work, or the second pull-down node Q2 controls the second pull-down control module 302 to work, so that the connection between the pull-up node P and the third voltage terminal V3 is connected and scanned. The connection between the output terminal Gout and the fourth voltage terminal V4 is connected before the connection between the cascaded output terminal Gout_sub and the third voltage terminal V3.
具体结合图2和图3所示,在第三阶段T3,第二控制端RESET输出高电平,而控制第二晶体管M2导通,使得上拉节点P的电位为第二电压端DIR2输出的低电平,此时与上拉节点P连通的晶体管均截止。由于第一信号端Clock1输出的高电平,故而,第一信号端Clock1控制第十四晶体管M14导通,将第一信号端Clock1输出的高电平传输至第二下拉节点Q2,且第一下拉节点Q1的电位为第三电压端V3输出的低电平;此时,第二下拉节点Q2控制第十晶体管M10、第十一晶体管M11和第十二晶体管M12导通,使得扫描输出端Gout的电位为第四电压端V4输出的低电平、上拉节点P的电位为第三电压端V3输出的低电平和级联输出端Gout_sub的电位为第三电压端V3输出的低电平。其中,由于第三电压端V3输出电压低于第四电压端V4输出电压,而第十五晶体管M15此时Vgs=第三电压端V3的电压值-第四电压端V4的电压值,即,第十五晶体管M15此时Vgs为负数,使得第十五晶体管M15的漏电流较小,提高了移位寄存单元的输出稳定性。此外,由于级联输出端Gout_sub输出电压值为第三电压端V3输出的更低的低电平,故而,能够有效的关闭上下级移位寄存单元中相应连通的晶体管,避免由于电压值较高造成误导通。Specifically as shown in Figure 2 and Figure 3, in the third stage T3, the second control terminal RESET outputs a high level, and controls the second transistor M2 to turn on, so that the potential of the pull-up node P is the output of the second voltage terminal DIR2 At this time, the transistors connected to the pull-up node P are all turned off. Due to the high level output by the first signal terminal Clock1, the first signal terminal Clock1 controls the turn-on of the fourteenth transistor M14 to transmit the high level output by the first signal terminal Clock1 to the second pull-down node Q2, and the first The potential of the pull-down node Q1 is the low level output by the third voltage terminal V3; at this time, the second pull-down node Q2 controls the tenth transistor M10, the eleventh transistor M11 and the twelfth transistor M12 to conduct, so that the scanning output terminal The potential of Gout is the low level output from the fourth voltage terminal V4, the potential of the pull-up node P is the low level output from the third voltage terminal V3, and the potential of the cascade output terminal Gout_sub is the low level output from the third voltage terminal V3 . Wherein, since the output voltage of the third voltage terminal V3 is lower than the output voltage of the fourth voltage terminal V4, and the fifteenth transistor M15 at this time Vgs=voltage value of the third voltage terminal V3−voltage value of the fourth voltage terminal V4, that is, The Vgs of the fifteenth transistor M15 is a negative number at this time, so that the leakage current of the fifteenth transistor M15 is small, and the output stability of the shift register unit is improved. In addition, since the output voltage value of the cascaded output terminal Gout_sub is a lower low level than that output by the third voltage terminal V3, it can effectively close the corresponding connected transistors in the upper and lower shift register units, avoiding cause misleading.
需要说明的是,在第三阶段T3,还可以将第一信号端Clock1设置为输出低电平,而将第二信号端Clock2设置为输出高电平,对此本申请实施例不做具体限制。It should be noted that in the third stage T3, the first signal terminal Clock1 can also be set to output a low level, and the second signal terminal Clock2 can be set to output a high level, which is not specifically limited in this embodiment of the present application. .
