具体实施方式
下面将结合附图，对本公开一些实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开所提供的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本公开保护的范围。
除非上下文另有要求，否则，在整个说明书和权利要求书中，术语“包括(comprise)”及其其他形式例如第三人称单数形式“包括(comprises)”和现在分词形式“包括(comprising)”被解释为开放、包含的意思，即为“包 含，但不限于”。在说明书的描述中，术语“一个实施例(one embodiment)”、“一些实施例(some embodiments)”、“示例性实施例(exemplary embodiments)”、“示例(example)”、“特定示例(specific example)”或“一些示例(some examples)”等旨在表明与该实施例或示例相关的特定特征、结构、材料或特性包括在本公开的至少一个实施例或示例中。上述术语的示意性表示不一定是指同一实施例或示例。此外，所述的特定特征、结构、材料或特点可以以任何适当方式包括在任何一个或多个实施例或示例中。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本公开实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
在描述一些实施例时，可能使用了“耦接”和“连接”及其衍伸的表达。例如，描述一些实施例时可能使用了术语“连接”以表明两个或两个以上部件彼此间有直接物理接触或电接触。又如，描述一些实施例时可能使用了术语“耦接”以表明两个或两个以上部件有直接物理接触或电接触。然而，术语“耦接”或“通信耦合(communicatively coupled)”也可能指两个或两个以上部件彼此间并无直接接触，但仍彼此协作或相互作用。这里所公开的实施例并不必然限制于本文内容。

本文中“适用于”或“被配置为”的使用意味着开放和包容性的语言，其不排除适用于或被配置为执行额外任务或步骤的设备。
本公开的实施例提供一种显示装置。
上述的显示装置包括如图1所示的显示面板100。显示面板100具有显示区(Active Area，AA)和至少位于AA区一侧的周边区S。
如图1所示，显示面板100包括设置于AA区中的多个亚像素P。
需要说明的是，图1中以上述多个亚像素P呈n行m列的阵列形式排列为例进行示意，但本发明实施例不限于此，上述多个亚像素P还可以以其他方式进行排布。其中，沿水平方向X排列成一排的亚像素P称为同一行亚像素，沿竖直方向Y排列成一排的亚像素P称为同一列亚像素。
在一些实施例中，如图1所示，亚像素P内设置有像素驱动电路20。
如图2所示，一个像素驱动电路20与至少一个发光器件L耦接，像素驱动电路20用于驱动发光器件L发光。
其中，该发光器件L还与第二电源电压信号端VSS电连接。
示例性地，第二电源电压信号端VSS传输直流低电平信号。
示例性地，发光器件L可以采用OLED或者发光二极管(Light Emitting Diode，LED)。在这种情况下，文中所述的工作时长可以被理解为发光器件L的发光时长；发光器件L的第一极和第二极分别为发光二极管的阳极和阴极。
在动态画面切换过程中，如果发光器件L工作时间较长，在一图像帧的显示图像切换至下一图像帧的显示图案的过程中，上一图像帧的显示画面会出现拖影，影响下一图像帧的显示画面，导致出现图像拖影(也称动态图像拖影)，降低显示效果。
本公开的一些实施例提供一种像素驱动电路20，如图2所示，包括：数据写入子电路201、驱动子电路202和时间控制子电路203。
数据写入子电路201至少与第一扫描信号端G1、数据信号端DATA和第一节点N1耦接。
驱动子电路202与第一节点N1、第二节点N2和第一电源电压信号端VDD耦接。
时间控制子电路203与第一节点N1、第二扫描信号端G2和控制信号端DB耦接。
其中，数据写入子电路201被配置为在第一扫描信号端G1处接收的第一扫描信号的控制下，将在数据信号端DATA处接收的数据信号写入第一节点N1。
驱动子电路202被配置为在第一节点N1的电压和在第一电源电压信号端VDD处接收的第一电源电压信号的控制下，驱动与第二节点N2耦接的发光器件L工作。
示例性地，第一电源电压信号为直流高电平信号。
时间控制子电路203被配置为在发光器件L工作预设时间之后，在第二 扫描信号端G2处接收的第二扫描信号的控制下，将在控制信号端DB处接收的控制信号传输至第一节点N1，使驱动子电路202断开，以控制发光器件L停止工作。
其中，发光器件L工作预设时间指的是发光器件L正常发光，以使显示装置显示正常图像的时间。在发光器件L停止工作的情况下，发光器件L不发光，显示装置呈现黑画面。
需要说明的是，可以根据显示装置实际显示正常图像的需要，设定发光器件L工作预设时间的时长，在此不做限定。
并且，本领域技术人员可以在保证发光器件L工作预设时间之后，显示装置切换成黑画面的情况下，对控制信号的电压大小进行设定。示例性地，控制信号端DB处接收的控制信号可以为固定电位信号，例如，直流低电平信号；或者，控制信号也可以为电位在设定电压范围内变化的信号，例如，插黑信号，该电位在设定电压范围内的信号可以控制发光器件L停止工作。
在此情况下，相比于在图像帧切换的过程中，发光器件L在下一图像帧到来之前持续工作，本公开的实施例中的发光器件L工作预设时间之后，发光器件L停止工作，即发光器件L停止发光，缩短了发光器件L的工作时长，使得在下一图像帧到来之前，显示装置可以在一段时间内呈现黑画面，延长了动态画面响应时间，从而避免由于发光器件L持续工作而导致在图像帧切换的过程中出现动态拖影，提高显示效果。
因此，本公开的实施例提供的像素驱动电路20，时间控制子电路203在发光器件L工作预设时间之后，将在控制信号端DB处接收的控制信号传输至第一节点N1，使驱动子电路202断开，控制发光器件L停止工作，发光器件L停止发光。相比于在图像帧切换的过程中，发光器件L在下一图像帧到来之前持续工作，本公开的实施例缩短了发光器件L的工作时长，使得在下一图像帧到来之前，显示装置可以在一段时间内呈现黑画面，延长了动态画面响应时间(Motion Picture Response Time，MPRT)，从而避免由于发光器件L持续工作而导致在图像帧切换的过程中出现动态拖影，提高了显示效果。并且，显示装置的刷新频率越高，动态画面响应时间越长，拖影对显示效果的影响越小。
示例性地，如图3所示，时间控制子电路203包括：第一晶体管T1。
其中，第一晶体管T1的控制极与第二扫描信号端G2耦接，第一晶体管T1的第一极与控制信号端DB耦接，第一晶体管T1的第二极与第一节点N1耦接。

其中，第二晶体管T2的控制极与第一节点N1耦接，第二晶体管T2的第一极与第二节点N2耦接，第二晶体管T2的第二极与第一电源电压信号端VDD耦接。

在一些实施例中，如图2所示，像素驱动子电路20还包括感测子电路204。
感测子电路204与第三扫描信号端G3、第二节点N2和感测信号端SE耦接。
感测子电路204被配置为在第三扫描信号端G3处接收的第三扫描信号的控制下，将在感测信号端SE处接收的感测信号传输至第二节点N2。
在此情况下，显示面板100还包括感测信号线(图中未示出)。感测信号线与感测信号端SE耦接。感测信号线向感测信号端SE提供感测信号。
此外，显示装置还包括外部补偿电路(图中未示出)。感测信号线与外部补偿电路耦接。感测子电路204还被配置为，在发光器件L不工作的时间段，在第三扫描信号端G3处接收的第三扫描信号的控制下，向感测信号端SE传输第二节点N2的电压。
在此情况下，感测信号线将第二节点N2的电压传输至外部补偿电路，外部补偿电路根据第二节点N2的电压，调整在后续显示过程中数据信号端DATA处接收的数据信号。这样，可以通过外部补偿的方式，对驱动子电路202中的第二晶体管T2的阈值电压进行补偿，避免了驱动子电路202向发光器件L提供的驱动电流的差异，提高了显示装置的亮度均一性。
示例性地，如图3所示，感测子电路204包括第四晶体管T4。
其中，第四晶体管T4的控制极与第三扫描信号端G3耦接，第四晶体管T4的第一极与感测信号端SE耦接，第四晶体管T4的第二极与第二节点N2耦接。
在一些实施例中，控制信号端DB与感测信号端SE为同一信号端。
示例性地，如图4所示，在时间控制子电路203包括第一晶体管T1的情 况下，第一晶体管T1的第一极与感测信号端SE耦接。
在此情况下，可以减少了像素驱动电路20的信号端的数量，减少了与信号端对应耦接的信号线的数量，扩大了显示面板100的布线空间。
在一些实施例中，第一扫描信号端G1和第三扫描信号端G3为同一信号端。
可以理解的是，数据写入子电路201和感测子电路204同步开启。
示例性地，如图5所示，在感测子电路204包括第四晶体管T4的情况下，第四晶体管T4的控制极与第一扫描信号端G1耦接。
在此情况下，减少了像素驱动电路20的信号端的数量，减少了与信号端对应耦接的信号线的数量，扩大了显示面板100的布线空间。
本公开的实施例提供一种移位寄存器电路RS。移位寄存器电路RS应用于上述任一实施例中的像素驱动电路20。
如图6所示，移位寄存器电路RS包括：第一输入子电路301、第一输出子电路302、第二输入子电路303和第二输出子电路304。

以下，以上述各个晶体管均为N型晶体管为例，对像素驱动电路20和应用于上述的像素驱动电路20的移位寄存器电路RS中的各个晶体管在不同的阶段的工作情况进行详细地举例说明。
其中，第一电压端V1的电压为直流低电平电压，第二电压端V2的电压为直流低电平电压。
需要说明的是，为了描述方便，对于像素驱动电路20，在控制信号端DB处接收的控制信号和在感测信号端SE处接收的感测信号均以直流低电平信号Vref表示(如图9所示)。
为了描述方便，移位寄存器电路RS各工作阶段(如图10所示的Q1～Q5)，与第一下拉节点PD1耦接的各降噪子电路的工作，与第二下拉节点PD2耦接的各降噪子电路的不工作的情况为例进行说明。
并且，以第一信号输入端IN1与第二信号输入端IN2为同一信号端进行说明，即，第一信号输入端IN1与第二信号输入端IN2传输的信号时序相同。
对于移位寄存器电路RS，在如图10所示的一图像帧(1F)中的第一阶段(Q1)，在像素驱动电路20接收到第一扫描信号之前，参考图6，第一输入子电路301将在第一信号输入端IN1处接收的信号传输至上拉节点PU，对上拉节点PU充电。

在移位寄存器电路RS包括第三输出子电路305的情况下，在上拉节点PU充电的同时，还对第三电容C3充电。此时，第七晶体管T7将低电平的第三时钟信号传输至第三信号输出端OUT3。
对于移位寄存器电路RS，在如图10所示的第二阶段(Q2)，在上拉节点PU的电压的控制下，第一输出子电路302开启，将在第一时钟信号端CLKA处接收的第一时钟信号传输至第一信号输出端OUT1，以向像素驱动电路20 的第一扫描信号端G1传输第一扫描信号。
在移位寄存器电路RS包括第三输出子电路305的情况下，在上拉节点PU的高电平的电压的控制下，第三输出子电路305开启，将在第三时钟信号端CLKC处接收的第三时钟信号传输至第三信号输出端OUT3，以向像素驱动电路20的第三扫描信号端G3传输第三扫描信号。
在移位寄存器电路RS包括移位信号输出子电路306的情况下，在上拉节点PU的高电平的电压的控制下，移位信号输出子电路306开启，将在第四时钟信号端CLKD处接收的第四时钟信号传输至移位信号输出端CR。
示例性地，如图7所示，上拉节点PU的电压为高电平，并且，由于第一电容C1和第二电容C2的自举作用，上拉节点PU的电位被进一步抬高，在上拉节点PU的高电平电压的控制下，第五晶体管T5导通，将在第一时钟信号端CLKA处接收的高电平的第一时钟信号传输至第一信号输出端OUT1。
在移位寄存器电路RS包括第三输出子电路305的情况下，第三电容C3将存储的电荷释放至上拉节点PU，由于自举作用将上拉节点PU的电位抬高，第七晶体管T7导通，将高电平的第三时钟信号传输至第三信号输出端OUT3。
在移位寄存器电路RS包括移位信号输出子电路306的情况下，在上拉节点PU的高电平的电压的控制下，第八晶体管T8导通，将在第四时钟信号端CLKD处接收的高电平的第四时钟信号传输至移位信号输出端CR。
需要说明的是，第一时钟信号端CLKA和第三时钟信号端CLKC处接收的信号的波形相同，但是不代表两者为同一信号。
另外，第二输出子电路304中的第六晶体管T6导通，将低电平的第二时钟信号传输至第二信号输出端OUT2，以向像素驱动电路20的第二扫描信号端G2传输低电平的第二扫描信号。
在此情况下，对于像素驱动电路20，在如图9所示的一图像帧(1F)中的第一阶段(P1)，参考图2，在第一扫描信号端G1处接收的第一扫描信号的控制下，数据信号端DATA与第一节点N1的连接，数据写入子电路201将在数据信号端DATA处接收的数据信号写入第一节点N1。
在像素驱动电路20包括感测子电路204的情况下，在第三扫描信号端G3处接收的第三扫描信号的控制下，感测子电路204将在感测信号端SE处接收的感测信号传输至第二节点N2。
示例性地，在图9中的第一阶段(P1)的第一时段(t1)，如图4所示，在第一扫描信号端G1处接收的第一扫描信号为高电平信号的情况下，第三晶体管T3导通，将在数据信号端DATA处接收的低电平的数据信号传输至第一节点 N1，对第一节点N1复位。
在第三扫描信号端G3处接收的第三扫描信号为高电平信号的情况下，第四晶体管T4导通，将在感测信号端SE处接收的低电平的感测信号传输至第二节点N2，对第二节点N2复位。
在图9中的第一阶段(P1)的第二时段(t2)，第一扫描信号仍为高电平信号，第三晶体管T3处于导通状态，将在数据信号端DATA处接收的高电平的数据信号写入第一节点N1，并对存储电容Cst充电。
对于移位寄存器电路RS，在如图10所示的第三阶段(Q3)，参考图6，在第一下拉节点PD1的电压的控制下，第一降噪子电路307将第一电压端V1的电压传输至第一信号输出端OUT1，对第一信号输出端OUT1进行降噪。第二降噪子电路308将第一电压端V1的电压传输至第二信号输出端OUT2，对第二信号输出端OUT2进行降噪。
示例性地，如图7所示，在第一下拉节点PD1的高电平电压的控制下，第九晶体管T9开启，将第一电压端V1的低电平电压传输至第一信号输出端OUT1，此时，第一信号输出端OUT1的信号为低电平信号。在第一下拉节点PD1的高电平电压的控制下，第十晶体管T10开启，将第一电压端V1的低电平电压传输至第二信号输出端OUT2，此时，第二信号输出端OUT2的信号为低电平信号。
在移位寄存器电路RS包括第三输出子电路305的情况下，第三降噪子电路309将第一电压端V1的电压传输至第三信号输出端OUT3，对第三信号输出端OUT3进行降噪。
示例性地，如图7所示，在第一下拉节点PD1的高电平电压的控制下，第十一晶体管T11开启，将第一电压端V1的低电平电压传输至第三信号输出端OUT3，此时，第三信号输出端OUT3的信号为低电平信号。
在移位寄存器电路RS包括移位信号输出子电路306的情况下，移位信号输出子电路306将第二电压端V2的电压传输至移位信号输出端CR，对移位信号输出端CR进行降噪。
示例性地，如图7所示，在第一下拉节点PD1的高电平电压的控制下，第十二晶体管T12开启，将第二电压端V2的低电平电压传输至移位信号输出端CR，此时，移位信号输出端CR的电位为低电平，对移位信号输出端CR降噪。
需要说明的是，与第一下拉节点PD1耦接的各降噪子电路，和与第二下拉节点PD2耦接的各降噪子电路，以一定的周期交替工作。本领域工作人员 可以根据实际情况下，对周期时长进行设计，在此不作限定。其中，在如图10所示的一图像帧内，第一下拉节点PD1的电位非固定低电平，第二下拉节点PD2的电位为固定低电平，即，与第一下拉节点PD1耦接的各降噪子电路工作，与第二下拉节点PD2耦接的各降噪子电路不工作。
此外，在一些实施例中，在与第一下拉节点PD1耦接的各降噪子电路不工作，与第二下拉节点PD2耦接的各降噪子电路工作的情况下，参考图6，在第二下拉节点PD2的电压的控制下，第一降噪子电路307将第一电压端V1的电压传输至第一信号输出端OUT1，对第一信号输出端OUT1进行降噪。第二降噪子电路308将第一电压端V1的电压传输至第二信号输出端OUT2，对第二信号输出端OUT2进行降噪。
示例性地，如图7所示，在第二下拉节点PD2的高电平电压的控制下，第十三晶体管T13开启，将第一电压端V1的低电平电压传输至第一信号输出端OUT1，此时，第一信号输出端OUT1的信号为低电平信号。在第二下拉节点PD2的高电平电压的控制下，第十四晶体管T14开启，将第一电压端V1的低电平电压传输至第二信号输出端OUT2，此时，第二信号输出端OUT2的信号为低电平信号。
在移位寄存器电路RS包括第三输出子电路305的情况下，第三降噪子电路309将第一电压端V1的电压传输至第三信号输出端OUT3，对第三信号输出端OUT3进行降噪。
示例性地，如图7所示，在第二下拉节点PD2的高电平电压的控制下，第十五晶体管T15开启，将第一电压端V1的低电平电压传输至第三信号输出端OUT3，此时，第三信号输出端OUT3的信号为低电平信号。
在移位寄存器电路RS包括移位信号输出子电路306的情况下，移位信号输出子电路306将第二电压端V2的电压传输至移位信号输出端CR，对移位信号输出端CR进行降噪。
示例性地，如图7所示，在第二下拉节点PD2的高电平电压的控制下，第十六晶体管T16开启，将第二电压端V2的低电平电压传输至移位信号输出端CR，此时，移位信号输出端CR的电位为低电平，对移位信号输出端CR降噪。
因此，在移位寄存器电路RS工作的第三阶段(Q3)，第一信号输出端OUT1、第二信号输出端OUT2、第三信号输出端OUT3和移位信号输出端CR均传输低电平信号，因此，像素驱动电路20的第一扫描信号端G1、第二扫描信号端G2和第三扫描信号端G3均接收低电平信号。
在此情况下，对于像素驱动电路20，在如图9所示的第二阶段(P2)，在第一扫描信号端G1处接收的第一扫描信号的控制下，数据信号端DATA与第一节点N1的连接断开，在第三扫描信号端G3处接收的第三扫描信号的控制下，感测子电路204断开。
驱动子电路202在第一节点N1的电压的控制下开启，并在第一电源电压信号端VDD处接收的第一电源电压信号的控制下，驱动子电路202输出驱动电流，以驱动与第二节点N2耦接的发光器件L发光。
示例性地，如图4所示，在第一扫描信号端G1处接收的低电平的第一扫描信号的控制下，第三晶体管T3截止，在第三扫描信号端G3处接收的低电平的第三扫描信号的控制下，第四晶体管T4截止。
在第一节点N1的高电平的电压的控制下，第二晶体管T2导通，第一电源电压信号端VDD的第一电源电压信号传输至第二节点N2，使得第二节点N2的电位上升。并且，由于存储电容Cst的自举作用，存储电容Cst的第一极和第二极的电压差不会发生突变，因此，第一节点N1的电位进一步抬升，使得第二晶体管T2持续导通。在此情况下，在第一电源电压信号端VDD的第一电源电压信号的控制下，第二晶体管T2输出驱动电流，驱动发光器件L工作(即正常发光)。
在像素驱动电路20驱动发光器件工作预设时间之后，对于移位寄存器电路RS，在如图10所示的第四阶段(Q4)中的第一时段(q1)，第二输入子电路303将在第二信号输入端IN2处接收的信号传输至上拉节点PU。
示例性地，第二输入子电路303将在第二信号输入端IN2处接收的高电平信号传输至上拉节点PU，以使上拉节点PU的电位为高电平电位。
在第四阶段(Q4)中的第二时段(q2)，第二输出子电路304在上拉节点PU的电压的控制下开启，将在第二时钟信号端CLKB处接收的第二时钟信号传输至第二信号输出端OUT2，以向像素驱动电路20的第二扫描信号端G2传输第二扫描信号。示例性地，在上拉节点PU的高电平电压的控制下，第六晶体管T6导通，将高电平的第二时钟信号传输至第二信号输出端OUT2，以向像素驱动电路20的第二扫描信号端G2传输高电平的第二扫描信号。
在此情况下，对于像素驱动电路20，在如图9所示的第三阶段(P3)，时间控制子电路202在第二扫描信号端G2处接收的第二扫描信号的控制下开启，将在控制信号端DB处接收的控制信号传输至第一节点N1。
在第一节点N1的电压的控制下，驱动子电路202断开，使得发光器件L中无驱动电流流过，发光器件L停止工作，缩短了发光器件L工作时长，增 加了动态画面响应时间，避免在动态画面切换过程中出现拖影。
示例性地，如图4所示，在第二扫描信号端G2处接收的高电平的第二扫描信号的控制下，第一晶体管T1导通，将在控制信号端DB处接收的低电平的控制信号传输至第一节点N1，此时，第一节点N1为低电平电压。
在第一节点N1的低电平电压的控制下，第二晶体管T2截止，第二晶体管T2停止驱动发光器件L工作，从而缩短了发光器件L的工作时长。
这样，在图像帧切换的过程中，在下一图像帧到来之前，发光器件L停止工作，缩短了发光器件L的发光时长，即发光器件L停止发光，显示装置可以在一段时间内呈现黑画面，延长了动态画面响应时间，从而避免由于发光器件L持续工作而导致在图像帧切换的过程中出现动态拖影，提高了显示效果。
此外，在上拉节点PU的高电平电压的控制下，移位信号输出子电路306中的第八晶体管T8导通，将在第四时钟信号端CLKD处接收的高电平的第四时钟信号传输至移位信号输出端CR。并且，在上拉节点PU的高电平电压的控制下，第一输出子电路302中的第五晶体管T5导通，将在第一时钟信号端CLKA处接收的低电平的第一时钟信号传输至第一信号输出端OUT1，第三输出子电路305中的第七晶体管T7导通，将第三时钟信号端CLKC处接收的低电平的第三时钟信号在第三信号输出端OUT3。在此情况下，像素驱动电路20的第一扫描信号端G1和第三扫描信号端G3均传输低电平信号，数据写入子电路201中的第三晶体管T3和感测子电路204中的第四晶体管T4均截止。
在如图10所示的第五阶段(Q5)，第二输入子电路303将在第二信号输入端IN2处接收的高电平信号传输至上拉节点PU，以使上拉节点PU的电位为高电平电位。
在第四阶段(Q4)中的第三时段(q3)，在第一下拉节点PD1为高电平电位的控制下，移位寄存器电路RS中的与第一下拉节点PD1耦接的第一降噪子电路307、第二降噪子电路308、第三降噪子电路309和第四降噪子电路310工作，分别对第一信号输出端OUT1、第二信号输出端OUT2、第三信号输出端OUT3和移位信号输出端CR降噪，具体工作方式与在第三阶段(Q3)的工作方式类似，在此不再赘述。
在如图10所示的第五阶段(Q5)中的第四时段(q4)，第二输入子电路303将在第二信号输入端IN2处接收的高电平信号传输至上拉节点PU，以使上拉节点PU的电位为高电平电位。
在第五阶段(Q5)中的第五时段(q5)，在上拉节点PU的电压的控制下，第 一输出子电路302开启，将在第一时钟信号端CLKA处接收的第一时钟信号传输至第一信号输出端OUT1，以向像素驱动电路20的第一扫描信号端G1传输第一扫描信号。
例如，在上拉节点PU的高电平电压的控制下，第五晶体管T5导通，将在第一时钟信号端CLKA处接收的高电平的第一时钟信号传输至第一信号输出端OUT1。
在移位寄存器电路RS包括第三输出子电路305的情况下，在上拉节点PU的高电平的电压的控制下，第三输出子电路305开启，将在第三时钟信号端CLKC处接收的第三时钟信号传输至第三信号输出端OUT3，以向像素驱动电路20的第三扫描信号端G3传输第三扫描信号。
示例性地，在上拉节点PU的高电平电压的控制下，第七晶体管T7导通，将在第三时钟信号端CLKC处接收的高电平的第三时钟信号传输至第三信号输出端OUT3。
在此情况下，对于像素驱动电路20，在如图9所示的第四阶段(P4)，参考图2，在第一扫描信号端G1处接收的第一扫描信号的控制下，数据写入子电路201将在数据信号端DATA处接收的数据信号写入第一节点N1。
示例性地，如图4所示，在第三扫描信号端G3处接收的高电平的第三扫描信号的控制下，第三晶体管T3导通，将在数据信号端DATA处接收的高电平的数据信号写入第一节点N1，第一节点N1的电位逐渐升高，相应的，第二节点N2的电位会随着第一节点N1的电位的同步变化。
在第三扫描信号端G3处接收的第三扫描信号的控制下，感测子电路204开启，将第二节点N2的电压传输至感测信号端SE。示例性地，在第三扫描信号端G3处接收的高电平的第三扫描信号的控制下，第四晶体管T4导通，将第二节点N2的电压传输至感测信号端SE。
在此情况下，与感测信号端SE耦接的感测信号线，将第二节点N2的电压传输至外部补偿电路，外部补偿电路根据第二节点N2的电压，调整在后续显示过程中数据信号端DATA处接收的数据信号。这样，可以通过外部补偿的方式，对驱动子电路202中的第二晶体管T2的阈值电压进行补偿，避免了驱动子电路202向发光器件L提供的驱动电流的差异，提高了显示装置的亮度均一性。
此外，在上拉节点PU的高电平电压的控制下，移位信号输出子电路306中的第八晶体管T8导通，将在第四时钟信号端CLKD处接收的高电平的第四时钟信号传输至移位信号输出端CR。
在第五阶段(Q5)中的第六时段(q6)，在第一下拉节点PD1为高电平电位的控制下，移位寄存器电路RS中的与第一下拉节点PD1耦接的第一降噪子电路307、第二降噪子电路308、第三降噪子电路309和第四降噪子电路310工作，分别对第一信号输出端OUT1、第二信号输出端OUT2、第三信号输出端OUT3和移位信号输出端CR降噪，具体工作方式与在第三阶段(Q3)的工作方式类似，在此不再赘述。

示例性地，如图11所示，第1级移位寄存器电路RS(1)的第一信号输入端IN1与起始信号线STU耦接。起始信号线STU被配置为传输起始信号，该栅极驱动电路10的第1级移位寄存器电路RS(1)在接收到上述起始信号后开始工作。除了第1级移位寄存器电路RS(1)以外，每一级移位寄存器电路的第一信号输入端IN1与其上一级移位寄存器电路的移位信号输出端CR耦接。
除了最后一级移位寄存器电路RS(N)以外，每一级移位寄存器单元还与其下一级移位寄存器电路的移位信号输出端CR的复位信号端耦接(图中未示出)，以进行复位。
需要说明的是，为了方便描述，图11仅示出了移位寄存器电路RS的第一信号输入端IN1和第二信号输入端IN2为同一信号端的情况。在移位寄存器电路RS的第一信号输入端IN1和第二信号输入端IN2为不同信号端的情况下，第二信号输入端IN2可以与一根信号线耦接(图中未示出)，该信号线传输至第二信号输入端IN2的信号可以使第二输入子电路303实现相应的功能。需要说明的是，任意相邻的两个级联的移位寄存器电路RS耦接不同的第一时钟信号线、第二时钟信号线、第三时钟信号线和第四时钟信号线。

需要说明的是，为了描述方便，本公开的实施例将一些信号端、一些信号端传输的信号、以及一些信号端所耦接的信号线均采用相同符号表示，但各自的属性不相同。
如图1所示，显示面板100中设置有中多条第一扫描信号线GL1(1)～GL1(n)、多条第二扫描信号线GL2(1)～GL2(n)、多条第三扫描信号线GL3(1)～GL3(n)和多条数据线DL(1)～DL(m)。
