本申请所提供的阵列基板显示面板及触控显示装置中，在阵列基板的非显示区引入M条第二开关控制线、多个第二开关单元组和多个触控信号端组，每个触控信号端组中所包含的触控信号端的数量与一个电极列中所包含的第一电极的数量相同。特别是，同一触控信号端组能够分别向同一电极列组中M个相邻的电极列提供触控检测信号，也就是说，M个电极列中的第一电极共用一个触控信号端组即可，相比现有技术中触控信号端与触控电极的数量一一对应的方案，本申请共用触控信号端组的方式，大大减小了触控信号端的数量，从而大大减小了从触控信号端所引出的走线的数量，当阵列基板的非显示区即边框区的走线数量减小时，边框的宽度即可得到一定程度上的压缩，因而有利于实现阵列基板、显示面板及触控显示装置的窄边框的设计。
本申请所提供的阵列基板的驱动方法中，在触控阶段，各电极列组中的至少一个电极列接收触控检测信号，至少一个电极列接收脉冲信号，而且触控检测信号和脉冲信号的波形相同，从而有利于减小在触控阶段未接收触控检测信号的电极列对正在进行触摸检测的电极列中的第一电极的信号造成影响，因而有利于增强阵列基板的触控检测性能，提升触控检测的精度。

应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步讨论。
图1所示为相关现有技术中所提供的一种显示面板900的结构示意图，该显示面板900通常包括呈阵列排布的触控电极块92和与各触控电极块92一一对应电连接的触控信号线93，每个触控电极块92通过相应的触控信号线93连接到集成电路91，以使得集成电路91能够接收到显示面板900任何一个区域的触控信号。此种设计方式使得显示面板的下边框区域中的走线过多，从而导致显示面板的下边框宽度较大，导致显示面板难以实现窄边框的需求。
图2所示为本申请实施例所提供的阵列基板的一种结构示意图，图3所示为本申请实施例所提供的阵列基板中第一电极的一种连接示意图，请参见图2和图3，本申请提供一种阵列基板100，包括：显示区10和围绕显示区10的非显示区11；
沿第一方向排布的多个电极列组20，每个电极列组20包括M个相邻的电极列21，该M个相邻的电极列21沿第二方向延伸并沿第一方向排布，各电极列21分别包括N个第一电极22，第一电极22位于显示区10，其中，M≥2，N≥2，第一方向和第二方向交叉；可选地，图3以M＝3，N＝4为例进行说明，需要说明的是，每个电极列组20所包含的电极列21的数量可以为更多个，每个电极列21中所包含的第一电极22的数量也可以为更多个，本申请再次不进行具体限定；
多条触控信号线30，各触控信号线30分别包括相互电连接的第一信号线31和第二信号线32，同一触控信号线30中，第一信号线31和第二信号线32与同一第一电极22电连接；
位于非显示区11的M条公共电压线VCOM、M条第一开关控制线VSW、多个第一开关单元组40，第一开关单元组40包括M个第一开关单元41；各电极列组20中：同一电极列21中的各第一电极22经对应的第一信号线31连接至同一第一开关单元41的第一极；同一第一开关单元组40中的各第一开关单元41的第二极分别连接至不同的公共电压线VCOM，同一第一开关单元组40中的各第一开关单元41的栅极连接至不同的第一开关控制线VSW；
位于非显示区11的M条第二开关控制线TPSW、多个第二开关单元组50、多个触控信号端组60，每个第二开关单元组50包括M个子开关单元组51，每个子开关单元组51包括N个第二开关单元52，每个触控信号端组60包括N个触控信号端SX；各电极列组20中：各第一电极22对应的第二信号 线32与第二开关单元组50中的第二开关单元52的第一极一一对应电连接；同一第二开关单元组50中，同一子开关单元组51中的各第二开关的栅极连接至同一第二开关控制线TPSW，不同子开关单元组51中的各第二开关的栅极分别连接至不同的第二开关控制线TPSW；同一触控信号端组60中的N个触控信号端分别与同一第二开关组中的任一子开关单元组51内的N个第二开关的第二极一一对应电连接。
现有设计中，由于每个触控电极块通过相应的触控信号线连接到集成电路，因而需要在集成电路上设计与触控电极块数量相同的触控信号端，但此种方式使得显示面板的下边框区域中的走线过多，从而导致显示面板的下边框宽度较大，导致显示面板难以实现窄边框的需求。
而本申请实施例所提供的显示面板中，以M＝3，N＝4为例，显示区10内设置有沿第一方向排布的多个电极列组20，每个电极列组20包括3个相邻的电极列21，各电极列21分别包括4个第一电极22；在非显示区11设置有3条第二开关控制线，分别为TPSW1、TPSW2和TPSW3，每个子开关单元组51包括4个第二开关单元52，每个触控信号端组60包括4个触控信号端；同一子开关单元组51中的各第二开关的栅极连接至同一第二开关控制线，不同子开关单元组51中的各第二开关的栅极分别连接至第二开关控制线TPSW1、TPSW2和TPSW3。特别是，同一触控信号端组60中的4个触控信号端分别与同一第二开关单元组50中任意子开关单元组51内的4个第二开关单元52的第二极一一对应电连接，该第二开关单元组50包括3个子开关单元组51，因此，相当于一个触控信号端组60能够分别向与3个子开关单元组51中的第二开关单元52电连接的3个电极列21提供触控检测信号，也就是说，3个电极列21中的第一电极22共用一个触控信号端组60即可，相比现有技术中触控信号端与触控电极的数量一一对应的方案，本申请共用触控信号端组60的方式，大大减小了触控信号端的数量，图3所示实施例中，触控信号端的数量仅为现有技术的触控信号端的数量的1/3，从而大大减小了从触控信号端所引出的走线的数量，当阵列基板100的非显示区即边框区的走线数量减小时，边框的宽度即可得到一定程度上的压缩，因而有利于实现阵列基板100的窄边框的设计。
本申请还在非显示区11引入了公共电压线VCOM、第一开关控制线VSW 和第一开关单元组40。在触控阶段，触控信号端组60向各电极列组20中的至少一个电极列21传输触控检测信号，公共电压线VCOM向各电极组中的至少一个电极列21传输脉冲信号，而且触控检测信号和脉冲信号的波形相同，从而有利于减小在触控阶段T2未接收触控检测信号的电极列21对正在进行触摸检测的电极列21中的第一电极22的信号造成影响，因而有利于增强阵列基板100的触控检测性能，提升触控检测的精度。
需要说明的是，图3所示实施例仅示出了一个电极列组20的连接关系，事实上，阵列基板100上会设置有重复排列的多个如图3所示的电极列组20，其他电极列组20在阵列基板100上的连接关系可参照图3执行，本申请不再一一示出。还需说明的是，为了清晰体现阵列基板100上第一电极22与第一开关单元41和第二开关单元52的连接关系，本申请的各个附图对这些部件进行了放大，因此并不代表实际的尺寸。
可选地，图4所示为本申请实施例所提供的阵列基板100中第一电极22的另一种连接示意图，该实施例示出了M＝2的情形，请参见图4，公共电压线VCOM包括第一公共电压线VCOMA和第二公共电压线VCOMB，第一开关控制线VSW包括第一甲开关控制线VSW1和第一乙开关控制线VSW2；第二开关控制线TPSW包括第二甲开关控制线TPSW1和第二乙开关控制线TPSW2；每个第二开关单元组50包括第一子开关单元组511和第二子开关单元组512；电极列组20包括相邻的奇数电极列25和偶数电极列26；
同一第一开关单元组40中，与奇数电极列25中的第一电极22电连接的第一开关单元41的栅极连接至第一甲开关控制线VSW1，第二极连接至第一公共电压线VCOMA；与偶数电极列26中的第一电极22电连接的各第一开关单元41的栅极连接至第一乙开关控制线VSW2，第二极连接至第二公共电压线VCOMB；
同一第二开关单元组50中，第一子开关单元组511中的各第二开关单元52的第一极与奇数电极列25中的各第一电极22电连接，第二子开关单元组512中的各第二开关单元52的第一极与偶数电极列26中的各第一电极22电连接；第一子开关单元组511中的各第二开关单元52的栅极连接至第二甲开关控制线TPSW1，第二子开关单元组512中的各第二开关单元52的栅极连接至第二乙开关控制线TPSW2；同一触控信号端组60中的各触控信号端同 时与第一子开关单元组511中的一个第二开关单元52的第二极以及第二子开关单元组512中的一个第二开关单元52的第二极电连接。
需要说明的是，图4所示实施例仅示出了两个电极列组20的连接关系，事实上，阵列基板100上会设置有重复排列的多个如图4所示的电极列组20，其他电极列组20在阵列基板100上的连接关系可参照图4执行，本申请不再一一示出。
具体地，请继续参见图4，当M＝2时，每个电极列组20包括两个电极列，分别是奇数电极列25和偶数电极列26。第一甲开关控制线VSW1和与奇数电极列25电连接的第一开关单元41的栅极电连接，用于控制与其连接的第一开关单元41的导通或截止；第一乙开关控制线VSW2和与偶数电极列26电连接的第一开关单元41的栅极电连接，用于控制与其连接的第一开关单元41的导通或截止。
第一公共电压线VCOMA用于向奇数电极列25发送信号，第二公共电压线VCOMB用于向偶数电极列26发送信号。第二甲开关控制线TPSW1和与奇数电极列25电连接的第二开关单元52的栅极电连接，用于控制与其连接的第二开关单元52的导通或截止；第二乙开关控制线TPSW2和与偶数电极列26电连接的第二开关单元52的栅极电连接，用于控制与其连接的第二开关单元52的导通或截止。一个触控信号端组60用于分别向同一电极列组20中的奇数电极列25和偶数电极列26传递触控检测信号。也就是说，两个电极列21共用一个触控信号端组60即可，相比现有技术中每个电极列21对应一个触控信号端组60的方式，本申请的触控信号端组60共用的方式能够减少一半的触控信号端的数量，从而与触控信号端连接的走线也可减少一半，为阵列基板100的边框区提供了可压缩空间，因而有利于实现窄边框设计。
以下将结合图5对图4所示阵列基板100的驱动方法进行说明，其中，图5所示为本申请实施例所提供的阵列基板100的一种驱动时序图。
在第一触控阶段T21，第二甲开关控制线TPSW1传输高电平信号，所有奇数电极列25的第一电极22接收触控信号端组60向其发送的触控检测信号；同时，第二乙开关控制TPSW2传输低电平信号，所有偶数电极列26的第一电极22不可接收触控检测信号；此时，第一甲开关控制线VSW1传输低电平信号，所有奇数电极列25中的第一电极22相互独立，第一乙开关控制线VSW2 传输高电平信号，第二公共电压线VCOMB向所有偶数电极列26发送脉冲信号。
在第二触控阶段T22，第二乙开关控制线TPSW2传输高电平信号，所有偶数电极列26的第一电极22接收触控信号端组60向其发送的触控检测信号；同时，第二甲开关控制线TPSW1传输低电平信号，所有奇数电极列25的第一电极22不可接收触控检测信号；此时，第一乙开关控号线VSW2传输低电平信号，所有偶数电极列26中的第一电极22相互独立，第一甲开关控制线VSW1传输高电平信号，第一公共电压线VCOMA向所有奇数电极列25发送脉冲信号。
现有技术中，当向某一电极列发送触控检测信号时，与其相邻的电极列中的第一电极与接收触控功能检测信号的电极列中的第一电极之间有电容耦合效应，因而在发生触控时，可能导致第一电极列向集成电路回读的信号失真，降低了触控检测的精度。因此，本申请中，在触控阶段T2，向同一电极列组20中的奇数电极列25和偶数电极列26发送的脉冲信号和触控检测信号的波形相同，能够避免相邻两个电极列21中的第一电极22之间发生电容耦合效应，从而有利于减小在触控阶段T2未接收触控检测信号的电极列21对正在进行触摸检测的电极列21中的第一电极22的信号造成影响，因而有利于增强阵列基板100的触控检测性能，提升触控检测的精度。
通常，阵列基板还包括多个像素行，每个像素行包括多个子像素，每个像素行对应一条扫描线，在显示阶段，扫描线依次对像素行进行扫描，从而实现显示功能。图5所示时序图中的CKV指的是控制扫描线对像素行进行扫描的时钟信号，在显示阶段T1，CKV为高电平，控制扫描线对像素行进行扫描。在触控阶段，CKV为低电平，低电平的脉冲信号的波形与触控检测信号的波形保持一致，这样同样有利于避免在触控阶段扫描线上的信号对第一电极造成影响，因而同样有利于增强阵列基板的触控检测性能，提升触控检测的精度。
需要说明的是，本申请提及的波形相同指的是脉冲信号和触控检测信号是相同幅度相同相位的。另外，图5所示的时序图仅示出了第一触控阶段T21对奇数电极列25进行触控检测，第二触控阶段T22再对偶数电极列26进行触控检测的过程，在本申请的一些其他实施例中，还可在第一触控阶段T21 先对偶数电极列26进行触控检测，在第二触控阶段T22再对奇数电极列25进行触控检测，本申请对此不进行具体限定。
可选地，请继续参见图4，第一子开关单元组511和第二子开关单元组512中，各第二开关单元52沿第一方向依次排布；奇数电极列25中，位于第n行的第一电极22与第一子开关单元组511中的第n个第二开关单元52通过第二信号线32电连接；偶数电极列26中，位于第n行的第一电极22与第二子开关单元组512中的第n个第二开关单元52通过第二信号线32电连接；其中，1≤n≤N。
具体地，请参见图4，该实施例中，奇数电极列25和偶数电极列26中位于第n行的第一电极22指的是在图4所示视角下，沿第二方向从上往下数第n个第一电极22；第一子开关单元组511和第二子开关单元组512中的第n个第二开关单元52指的是沿第一方向从左往右数的第n个电极。本申请将各电极列21中的第n个第一电极22与子开关单元组51中的第n个第二开关单元52一一对应电连接，按此规则设置各电极列21中第一电极22与第二开关单元52的电连接关系，使得各电极列21中的第一电极22与各开关单元组中第二开关单元52的连接顺序保持一致，有利于降低阵列基板100的布线复杂度，提高阵列基板100的生产效率。
需要说明的是，本申请以电极列21中的第n个第一电极为沿第二方向从上往下数第n个第一电极22，子开关单元组51中的第n个第二开关单元52为沿第一方向从左往右数第n各第二开关单元52为例进行说明，在本申请的一些其他实施例中，电极列21中的第n个第一电极还可为沿第二方向从下往上数第n个第一电极22，子开关单元组51中的第n个第二开关单元52还可为沿第一方向从右往左数第n各第二开关单元52，本申请对此不进行具体限定。
可选地，图6所示为本申请实施例中同一触控信号端组60与电极列21的一种连接关系图，同一触控信号端组60中，与同一触控信号端电连接的两个第一电极22位于不同行。
具体地，请继续参见图6，该实施例中，触控信号端SX1与奇数电极列25中的第一个第一电极22以及偶数电极列26中的第二个第一电极22电连接，触控信号端SX2与奇数电极列25中的第二个第一电极22以及偶数电极列26中的第一个第一电极22电连接，触控信号端SX3与奇数电极列25中的第三 个第一电极22以及偶数电极列26中的第四个第一电极22电连接，触控信号端SX4与奇数电极列25中的第四个第一电极22以及偶数电极列26中的第三个第一电极22电连接，如此，使得与同一触控信号端连接的两个第一电极22均位于不同行，此种设计有利于避免当将与同一触控信号端连接的两个第一电极22设置在同一行时、这两个第一电极22之间形成的串扰现象，因而有利于进一步提升阵列基板100的触控检测精度。
可选地，图7所示为本申请实施例中同一触控信号端组60与电极列的另一种连接关系图，同一触控信号端组60中的各触控信号端沿第一方向依次排布；
第m个触控信号端与第一子开关单元组511中的第m个第二开关单元52的第二极电连接，并与第二子开关单元组512中的第(N-m+1)个第二开关单元52的第二极电连接，其中，1≤m≤N。
具体地，请继续参见图7，该实施例中，触控信号端SX1与奇数电极列25中的第一个第一电极22以及偶数电极列26中的第四个第一电极22电连接，触控信号端SX2与奇数电极列25中的第二个第一电极22以及偶数电极列26中的第三个第一电极22电连接，触控信号端SX3与奇数电极列25中的第三个第一电极22以及偶数电极列26中的第二个第一电极22电连接，触控信号端SX4与奇数电极列25中的第四个第一电极22以及偶数电极列26中的第一个第一电极22电连接。采用此种连接方式，有利于增大与至少部分同一触控信号端连接的第一电极22之间的距离，例如与触控信号端SX1连接的第一电极22中，一个位于第一行另一个位于最后一行，进而有利于从最大程度上避免这两个电极之间形成的串扰现象，更加有利于提升阵列基板100的触控检测精度。当然该实施例仅以同一电极列21包括4个第一电极22为例进行说明，在本申请的一些其他实施例中，同一电极列21还可包括更多个第一电极22，第一电极22与触控信号端的连接关系可参照上述规则，本申请对此不进行具体限定。
可选地，图8所示为本申请实施例中同一触控信号端组60与电极列21的另一种连接关系图，同一触控信号端组60中的各触控信号端沿第一方向依次排布；
第m个触控信号端与第二子开关单元组512中的第m个第二开关单元52的第二极电连接，并与第一子开关单元组511中的第(N-m+1)个第二开关单元52的第二极电连接，其中，1≤m≤N。
具体地，请继续参见图8，该实施例中，触控信号端SX1与偶数电极列26中的第一个第一电极22以及奇数电极列25中的第四个第一电极22电连接，触控信号端SX2与偶数电极列26中的第二个第一电极22以及奇数电极列25中的第三个第一电极22电连接，触控信号端SX3与偶数电极列26中的第三个第一电极22以及奇数电极列25中的第二个第一电极22电连接，触控信号端SX4与偶数电极列26中的第四个第一电极22以及奇数电极列25中的第一个第一电极22电连接。采用此种连接方式，有利于增大与至少部分同一触控信号端连接的第一电极22之间的距离，例如与触控信号端SX1连接的第一电极22中，一个位于第一行另一个位于最后一行，同样有利于从最大程度上避免这两个电极之间形成的串扰现象，更加有利于提升阵列基板100的触控检测精度。当然该实施例仅以同一电极列21包括4个第一电极22为例进行说明，在本申请的一些其他实施例中，同一电极列21还可包括更多个第一电极22，第一电极22与触控信号端的连接关系可参照上述规则，本申请对此不进行具体限定。
可选地，请结合图2-图4，本申请实施例所提供的阵列基板100中，公共电压线VCOM、第一开关控制线VSW和第一开关单元组40位于显示区10第一侧的非显示区11，第二开关控制线TPSW、第二开关单元组50和触控信号端组60位于显示区10第二侧的非显示区11；沿第二方向，第一侧和第二侧相对设置。
具体地，本申请将公共电压线VCOM、第一开关控制线VSW和第一开关单元组40设置于显示区10第一侧的非显示区11，将第二开关控制线TPSW、第二开关单元组50和触控信号端组60设置于显示区10第二侧的非显示区11，合理利用阵列基板100上非显示区11的空间，避免将这些部件集中于阵列基板100同一侧的非显示区11而导致该侧非显示区11宽度过大，即边框宽度过大的情形，因此上述排布方式有利于进一步实现阵列基板100的窄边框设计。
可选地，请参见图3和图4，第一信号线31和第二信号线32均沿第二方向延伸，且与同一第一电极22对应的触控信号线30中，第一信号线31和第二信号线32通过同一连接过孔70与第一电极22电连接。
具体地，本申请将第一信号线31和第二信号线32均设置为均沿第二方向延伸，使得与同一第一电极22对应的第一信号线31和第二信号线32可位于同一直线上，在实际制作过程中，采用同一制程即可同时完成第一信号线31和第二信号线32的制作，因而有利于简化阵列基板100的生产工序。而且，当第一信号线31和第二信号线32通过同一连接过孔70电连接时，将触控信号线30与对应的第一电极22之间的连接过孔70的数量减少至最低，采用一个连接过孔即可实现第一电极22同时与第一信号线31和第二信号线32的电连接，因此有利于进一步简化阵列基板100的生产工序，提升阵列基板100的生产效率。
可选地，请参见图4，各第一开关单元41分别包括一个第一晶体管71，各第二开关单元52分别包括一个第二晶体管72。本申请中，第一晶体管71和第二晶体管72可同时体现为PMOS管，或者，第一晶体管71和第二晶体管72可同时体现为NMOS管，或者，第一晶体管71为PMOS管，第二晶体管72为NMOS管；或者，第一晶体管71为NMOS管，第一晶体管72为PMOS管。其中，PMOS管是栅极低电平导通，高电平断开；NMOS管是栅极高电平导通，低电平断开。在实际生产过程中，可根据实际需求选择第一开关单元41为PMOS管或NMOS管，第二开关单元52为PMOS管或NMOS管，本申请对此不进行具体限定。
基于同一发明构思，本申请还提供一种阵列基板100的驱动方法，用于驱动本申请上述任一实施例所提供的阵列基板100，驱动方法包括触控阶段T2的驱动方法，其中：
请结合图3和图4，在触控阶段，各电极列组20中的至少一个电极列21对应的第二开关单元52导通、第一开关单元41截止，触控信号端组60通过第二信号线32向与导通的第二开关单元52电连接的电极列21提供触控检测信号；同时，各电极列组20中的其他电极列21对应的第二开关单元52截止、第一开关单元41导通，公共电压线VCOM通过第一信号线31向与导通的第一开关单元41电连接的电极列21提供脉冲信号；其中，触控检测信号和脉冲信号的波形相同。

在第二触控阶段T22，第一开关控制线VSW2向与其连接的第一开关单元41发送低电平控制信号，第二开关控制线TPSW2向与其连接的第二开关单元52发送高电平控制信号，使得各电极列组20中的第二电极列82对应的第二开关单元52导通、第一开关单元41截止，触控信号端组60通过第二信号线32向第二电极列82提供触控检测信号；同时，第一开关控制线VSW1向与其连接的第一开关单元41发送高电平控制信号，第一开关控制线VSW3向与其连接的第一开关单元41发送高电平控制信号，第二开关控制线TPSW1向与其连接的第二开关单元52发送低电平控制信号，第二开关控制线TPSW3向与其连接的第二开关单元52发送低电平控制信号，使各电极列组20中第一电极列81和第三电极列83对应的第二开关单元52截止、第一开关单元41导通，公共电压线VCOMA和VCOMC通过第一信号线31向与第一电极列81和第三电极列83提供脉冲信号；

现有技术中，当向某一电极列发送触控检测信号时，与其相邻的电极列中的第一电极与接收触控功能检测信号的电极列中的第一电极之间有电容耦合效应，因而在发生触控时，可能导致第一电极列向集成电路回读的信号失真，降低了触控检测的精度。因此，在触控阶段T2，本申请向同一电极列组20中的至少一个电极列发送触控检测信号的同时，向其他电极列发送脉冲信号，而且脉冲信号和触控检测信号的波形相同，能够避免相邻两个电极列中的第一电极之间发生电容耦合效应，从而有利于减小在触控阶段T2未接收触控检测信号的电极列对正在进行触摸检测的电极列中的第一电极的信号造成影响，因而有利于增强阵列基板的触控检测性能，提升触控检测的精度。
可选地，请结合图4和图5，公共电压线VCOM包括第一公共电压线VCOMA和第二公共电压线VCOMB，第一开关控制线VSW包括第一甲开关控制线VSW1和第一乙开关控制线VSW2；第二开关控制线TPSW包括第二甲开关控制线TPSW1和第二乙开关控制线TPSW2；电极列组20包括相邻的奇数电极列25和偶数电极列26；触控阶段T2包括第一触控阶段T21，其中：

具体地，在第一触控阶段T21，第二甲开关控制线TPSW1传输高电平信号，所有奇数电极列25的第一电极22接收触控信号端组60向其发送的触控检测信号；同时，第二乙开关控制线TPSW2传输低电平信号，所有偶数电极列26的第一电极22不可接收触控检测信号；此时，第一甲开关控号线VSW1传输低电平信号，所有奇数电极列25中的第一电极22相互独立，第一乙开关控制线VSW2传输高电平信号，第二公共电压线VCOMB向所有偶数电极列26发送脉冲信号。在触控阶段T2，本申请向同一电极列组20中的奇数电极列25和偶数电极列26发送的脉冲信号和触控检测信号的波形相同，能够避免相邻两个电极列21中的第一电极22之间发生电容耦合效应，从而有利于减小在触控阶段T2未接收触控检测信号的电极列21对正在进行触摸检测的电极列21中的第一电极22的信号造成影响，因而有利于增强阵列基板100的触控检测性能，提升触控检测的精度。
可选地，请继续结合图4和图5，触控阶段T2还包括第二触控阶段T22，其中：
在第二触控阶段T22，第二甲开关控制线TPSW1向与其连接的第二开关单元52发送控制信号，使与其连接的各第二开关单元52截止；第一甲开关控制线VSW1向与其连接的第一开关单元41发送控制信号，使与其连接的第一开关单元41导通，第一公共电压线VCOMA向奇数电极列25提供脉冲信号；同时，第二乙开关控制线TPSW2向与其连接的第二开关单元52发送控制信号，使与其连接的各第二开关单元52导通；第一乙开关控制线VSW2向与其连接的第一开关单元41发送控制信号，使与其连接的第一开关单元41截止，触控信号端组60向偶数电极列26提供触控检测信号。
具体地，在第二触控阶段T22，第二乙开关控制线TPSW2传输高电平信号，所有偶数电极列26的第一电极22接收触控信号端组60向其发送的触控检测信号；同时，第二甲开关控制线TPSW1传输低电平信号，所有奇数电极列25的第一电极22不可接收触控检测信号；此时，第一乙开关控制线VSW1传输低电平信号，所有偶数电极列26中的第一电极22相互独立，第一甲开关控制线VSW2传输高电平信号，第一公共电压线VCOMA向所有奇数电极列25发送脉冲信号。在触控阶段T2，本申请向同一电极列组20中的奇数电 极列25和偶数电极列26发送的脉冲信号和触控检测信号的波形相同，能够避免相邻两个电极列21中的第一电极22之间发生电容耦合效应，从而有利于减小在触控阶段T2未接收触控检测信号的电极列21对正在进行触摸检测的电极列21中的第一电极22的信号造成影响，因而有利于增强阵列基板100的触控检测性能，提升触控检测的精度。
可选地，请结合图4和图5，本申请实施例所提供的驱动方法还包括显示阶段T1的驱动方法，其中：
在显示阶段T1，第二甲开关控制线TPSW1向与其连接的第二开关单元52发送低电平控制信号，使与其连接的各第二开关单元52截止；第二乙开关控制线TPSW2向与其连接的第二开关单元52发送低电平控制信号，使与其连接的各第二开关单元52截止；第一甲开关控制线VSW1向与其连接的第一开关单元41发送控制信号，使与其连接的第一开关单元41导通；第一乙开关控制线VSW2向与其连接的第一开关单元41发送控制信号，使与其连接的第一开关单元41导通；第一公共电压线VCOMA向奇数电极列25提供公共电压信号，第二公共电压线VCOMB向偶数电极列26提供公共电压信号。
具体地，在显示阶段T1，第二甲开关控制线TPSW1和第二乙开关控制线TPSW2均向与其连接的第二开关单元52传输低电平信号，使各第二开关单元52均截止；同时，第一甲开关控制线VSW1和第二乙开关控制线TPSW2均向与其连接的第一开关单元41传输高电平信号，使各第一开关单元41均导通，第一公共电压线VCOMA第一公共电压线VCOMA向奇数电极列25提供公共电压信号，第二公共电压线VCOMB向偶数电极列26提供公共电压信号。
在显示阶段T1，第一电极22复用为公共电极接收公共电压信号；在触控阶段T2，第一电极22复用为触控电极接收触控检测信号或脉冲信号。公共电极和触控电极均复用第一电极22的方式，有利于简化阵列基板100上的膜层结构，从而有利于简化阵列基板100的生产工序，提高阵列基板100的生产效率。
可选地，请参见图5，第一触控阶段T21和第二触控阶段T22同时位于相邻两个显示阶段T1之间。若在第一触控阶段T21和第二触控阶段T22之间设置显示阶段T1，当触摸主体对阵列基板100进行触摸的瞬间，阵列基板100对应的电极列21可能并未开始接收触控检测信号，可能需要等一段时间才能 接收到触控检测信号，因此降低了阵列基板100的触控灵敏度。而本申请将第一触控阶段T21和第二触控阶段T22所构成的触控阶段T2、与显示阶段T1交替执行，也就是说，第一触控阶段T21和第二触控阶段T22之间并未设置显示阶段T1，有利于提升阵列基板100的触控灵敏度，提升用户的触控体验效果。
基于同一发明构思，本申请还提供一种显示面板200，请参见图11，图11所示为本申请实施例所提供的显示面板200的一种结构示意图，该一种显示面板200，包括控制芯片400和本申请上述实施例所提供的任一阵列基板100；驱动芯片400绑定于非显示区，且图2和图3所示的与第二开关控制线、第二开关单元组和触控信号端组同时位于显示区的同一侧；各触控信号端组60中的触控信号端分别与驱动芯片400电连接。本申请实施例所提供的显示面板200的实施例可参见上述阵列基板100的实施例，重复之处不再赘述。
基于同一发明构思，本申请还提供一种触控显示装置300，请参见图12，图12所示为本申请实施例所提供的触控显示装置300的一种结构示意图，该触控显示装置300包括本申请实施例所提供的显示面板200。本申请实施例所提供的触控显示装置300的实施例可参见上述阵列基板100的实施例，重复之处不再赘述。本申请所提供的触控显示装置300可以为：手机、平板电脑、电视机、显示器、笔记本电脑、数码相框等任何具有显示功能的产品或部件。
需要说明的是，本申请所提供的触控显示装置300除可体现为上述具有显示功能的产品或部件外，还可应用于车载显示领域，例如，可用作车载导航仪或者其他车载显示屏等。
通过上述实施例可知，本发明提供的阵列基板及驱动方法、显示面板及触控显示装置，至少实现了如下的有益效果：
本申请所提供的阵列基板显示面板及触控显示装置中，在阵列基板的非显示区引入M条第二开关控制线、多个第二开关单元组和多个触控信号端组，每个触控信号端组中所包含的触控信号端的数量与一个电极列中所包含的第一电极的数量相同。特别是，同一触控信号端组能够分别向同一电极列组中M个相邻的电极列提供触控检测信号，也就是说，M个电极列中的第一 电极共用一个触控信号端组即可，相比现有技术中触控信号端与触控电极的数量一一对应的方式，本申请共用触控信号端组的方式，大大减小了触控信号端的数量，从而大大减小了从触控信号端所引出的走线的数量，当阵列基板的非显示区即边框区的走线数量减小时，边框的宽度即可得到一定程度上的压缩，因而有利于实现窄边框的设计。
本申请所提供的阵列基板的驱动方法中，在触控阶段，各电极列组中的至少一个电极列接收触控检测信号，至少一个电极列接收脉冲信号，而且触控检测信号和脉冲信号的波形相同，从而有利于减小在触控阶段未接收触控检测信号的电极列对正在进行触摸检测的电极列中的第一电极的信号造成影响，因而有利于增强阵列基板的触控检测性能，提升触控检测的精度。
虽然已经通过例子对本发明的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上例子仅是为了进行说明，而不是为了限制本发明的范围。本领域的技术人员应该理解，可在不脱离本发明的范围和精神的情况下，对以上实施例进行修改。本发明的范围由所附权利要求来限定。
