Description

触控显示面板、制备方法、驱动方法及显示装置 技术领域
本发明涉及显示技术领域，尤其涉及触控显示面板、制备方法、驱动方法及显示装置。
背景技术
目前，随着显示技术的发展，显示技术被广泛应用于电视、手机以及公共信息的显示，大尺寸显示面板逐渐成为人们生活中比较重要的一部分，同时随着显示技术的飞速发展，触摸屏(Touch Screen Panel)已经逐渐遍及人们的生活中，在追求优异体验功能的今天，触控性能一直是大尺寸显示面板的一大缺陷，或受限于技术或受限于成本。
随着触摸屏技术的发展，随着市场要求，整体模组减薄是市场发展趋势，所以触摸结构由触摸传感外挂式向触摸传感内嵌式发展，这样既可以实现触控面板的厚度减薄，也可以在很大程度上降低触摸屏的成本。目前内嵌式触控面板主要有三种类型：电阻式触控面板、电容式触控面板、光学式触控面板。相应的内嵌式触控技术现已初步运用于小尺寸显示屏中，其优异的触控性能成为未来触控设计的方向，因此，也为实现大尺寸显示面板的优异触控性能，提供了努力的方向。
在现有技术中，自电容式的触控面板的实现原理如图1所示，一般地，单个触控点电极m设计成5mm*5mm左右的方形电极，然后将该电极用一根导线n连接至触控芯片p内部，通过触控芯片p给该电极施加驱动信号，并且该电极m可以自己接收反馈信号，即当手指未触控时，电极m所承受的电容为一固定值；当手指触控时，电极m承受的电容为手指电容加上原有电容，由于电容大小不同，信号的RC延迟(resistance capacitance delay)时间也不相同，这样手指触控的前后就会接收到不一样的电信号，从而实现触控点的确定，其中由于手指为直接耦合的方式，故手指引起的触控变化量会比较大，触控点易于确定。然而这种设计方案中，连接电极与触控芯片的走线需要设置在触控面板两侧的边框区域，这样就需要增大边框区域的面积，不利于触控面板的窄边框设计。
因此，如何实现触控显示面板的窄边框设计，同时提高触控显示面板的触控性能，是本领域技术人员亟待解决的技术问题。

具体实施方式
下面结合附图，对本发明实施例提供的触控显示面板、其制备方法、驱动方法及显示装置的具体实施方式进行详细地说明。
附图中各膜层的厚度和区域的大小形状不反映触控显示面板各部件的真实比例，目的只是示意说明本发明的内容。
本发明实施例提供了一种自电容式触控显示面板，如图2所示，可以包括：具有第一金属层和呈矩阵排列的自电容触控电极1的阵列基板，以及触控芯片4。如图 3所示，每个自电容触控电极1包括多个公共电极2，如图2所示，第一金属层包括多条与自电容触控电极1一一对应的触控引线3，每个自电容触控电极1通过对应的触控引线3与触控芯片4相连。
触控引线3用于在显示阶段向自电容触控电极1传递公共电极信号，在触控阶段向自电容触控电极1传递触控扫描信号，且将发生触控位置处的自电容触控电极1产生的触控信号传输到触控芯片4。
本发明实施例提供的上述自电容式触控显示面板，可以包括具有呈矩阵排列的自电容触控电极1和第一金属层的阵列基板；其中，每个自电容触控电极1包括多个公共电极2，第一金属层包括多条与自电容触控电极1一一对应的触控引线3，每个自电容触控电极1通过对应的触控引线3与触控芯片4相连；触控引线3用于在显示阶段向自电容触控电极1传递公共电极信号，在触控阶段向自电容触控电极1传递触控扫描信号，且将发生触控位置处产生的触控信号传输到触控芯片4，这样自电容式触控显示面板在触控阶段复用公共电极为自电容触控电极，通过单独设置一层第一金属层，将触控引线设置于第一金属层上，每个自电容触控电极通过对应的触控引线连接至触控芯片实现触控功能。相对于现有技术在显示面板周边区域设置触控引线以实现触控功能，本发明实施例提供的触控显示面板单独设置一层第一金属层，可将触控引线设置在周边原有的电路图案之上或上方，相对于现有技术不需要多余的边框位置，有利于实现窄边框设计，同时在触控阶段复用公共电极为自电容触控电极，如图3所示，可以将公共电极2设置于由相邻栅线N与相邻数据线M定义的区域，这样公共电极2与栅线N、数据线M无交叠，在触控阶段，自电容触控电极与其他信号线之间的寄生电容很小，有利于提高触控性能。
在具体实施时，本发明实施例提供的上述自电容式触控显示面板中，为了实现自电容式触控显示面板在触控阶段的触控功能，单独设置一层第一金属层，进而可以将触控引线设置于第一金属层上。这样相对于现有技术中采用增大显示面板的边框区域来设置触控引线的方式，本发明实施例单独设置一层第一金属层来设置触控引线可以实现触控显示面板的窄边框设计，如图4所示，在栅极金属层Gate紧邻阵列基板的衬底基板设置的情况下，用于设置触控引线的第一金属层(触控引线3所在位置)可以位于栅极金属层Gate和源漏电极层SD之间且三者相互绝缘，其中触控引线3与自电容触控电极1相连接的位置设置有过孔U，进而通过过孔U实现自电容触控电极1与触控引线3的电性连接；也可以将第一金属层设置于源漏电极层之上且相互绝缘，以实现触控引线与自电容触控电极的连接，上述两者方式均可以实现将触控引 线设置于第一金属层上，当然也可以根据实际生产工艺和产品要求，对第一金属层的设置位置进行调整以实现触控功能，在此不作限定。
在具体实施时，本发明实施例提供的上述自电容式触控显示面板中，为了实现将各自电容触控电极连接至触控芯片，以实现触控显示面板在触控阶段的触控功能，因此各触控引线将各自对应的自电容触控电极一一对应连接至触控芯片，由于自电容触控电极呈矩阵排列的方式，如图2所示，因此触控引线3包括沿栅线N方向延伸的第一部分31和沿数据线M方向延伸的第二部分32，这样各触控引线3与各自电容触控电极1一一对应，通过沿栅线N延伸的第一部分31与各自电容触控电极1相连，再通过沿数据线M延伸的第二部分32连接至触控芯片4，采用该连接方式时触控芯片4设置于沿数据线延伸的方向上；也可以通过沿数据线延伸的第二部分与各自电容触控电极相连，再通过沿栅线延伸的第一部分连接至触控芯片，采用该连接方式时触控芯片设置于沿栅线延伸的方向上，在此不作限定。
在具体实施时，本发明实施例提供的上述自电容式触控显示面板中，如图2所示，第一金属层包括：多个与自电容触控电极1一一对应的基台P；基台P设置有过孔U，自电容触控电极1通过基台P与相应的触控引线3过孔连接。
具体地，本发明实施例提供的上述自电容式触控显示面板中，为了实现自电容触控电极1与触控引线3的连接，需要对自电容触控电极1与触控引线3之间进行过孔连接，为了便于实施过孔工艺，因此在第一金属层上设置与各自电容触控电极1一一对应的基台P，这样在基台P位置便于实施过孔工艺，有助于实现自电容触控电极与触控引线的良好电性连接。当然，本领域技术人员可以根据需要选择是否设置基台P，即自电容触控电极1可以通过基台P与各自的触控引线3相连，也可以直接与各自的触控引线3相连。
在具体实施时，本发明实施例提供的上述自电容式触控显示面板中，如图3所示，每个自电容触控电极1包括的多个公共电极2可以呈矩阵排列，每个自电容触控电极1中的每行公共电极中的多个公共电极2之间通过连接线5相连，每个自电容触控电极1中相邻行的且位于同一列的公共电极2之间通过第一金属层上的跳线L连接或通过像素电极层上的跳线L连接。
具体地，本发明实施例提供的上述自电容式触控显示面板中，将公共电极2复用为自电容触控电极，在触控阶段以实现触控功能，其中公共电极位于阵列基板的衬底基板上，与栅极位于同层，每个自电容触控电极包括多个公共电极，为了实现自电容触控电极的触控功能，需要将一个自电容触控电极所包含的多个公共电极连接成一 个完整的自电容触控电极，这样才能实现自电容触控电极的触控功能。一般地，自电容触控电极包括的多个公共电极可以呈矩阵排列，因此可以将每个自电容触控电极中的每行公共电极中的多个公共电极之间通过连接线相连，每个自电容触控电极中相邻行的公共电极之间通过第一金属层上的跳线连接或通过像素电极层上的跳线连接。这样利用阵列基板中现有金属膜层，例如第一金属层或者像素电极层，当然也可以是其他可以设置跳线以连接相邻行公共电极的金属层，这样将相邻行公共电极通过其他金属层设置的跳线连接，避免与栅线形成交叉短路，可以实现一个自电容触控电极包含的各个公共电极连接为一个整体，进而实现自电容触控电极的触控功能，同时利用现有金属膜层设置跳线，可以简化阵列基板的制作工艺，简化膜层结构，降低生产成本。
在具体实施时，本发明实施例提供的上述自电容式触控显示面板中，用于连接每个自电容触控电极中的每行公共电极中的多个公共电极之间的连接线与栅线同层设置且相互平行。
具体地，本发明实施例提供的上述自电容式触控显示面板中，公共电极位于衬底基板上可与栅极同层设置，因此用于连接每个自电容触控电极中的每行公共电极中的多个公共电极之间的连接线可以与栅线同层设置且相互平行，当然连接线可以采用栅极金属材料，这样在阵列基板制作过程中，可以采用同一次构图工艺形成栅极、栅线、连接线，这样可以简化阵列基板的制作工艺、降低生产成本。
在具体实施时，本发明实施例提供的上述自电容式触控显示面板中，还可以包括：第二金属层，该第二金属层与栅极金属层同层设置且与第一金属层并联设置。
具体地，本发明实施例提供的上述自电容式触控显示面板中，为了提高触控显示面板的驱动频率，可以进一步降低第一金属层上的触控引线的电阻，即通过在栅极金属层上设置第二金属层，第二金属层的图案设置成多个公共电极的形状，与第一金属层上的触控引线平行设置，第二金属层包括的公共电极与栅极可同一次构图工艺形成，且第二金属层包括的公共电极在相应的位置通过过孔与第一金属层上的触控引线连接形成并联设置，这样可以实现第一金属层与第二金属层的并联设置，从而可以将低第一金属层的电阻，其触控显示面板的触控驱动频率可以大约提高30％。
基于同一发明构思，本发明实施例提供了一种本发明实施例提供的上述自电容式触控显示面板的制备方法，如图5所示，可以具体包括：
S101、在衬底基板上形成呈矩阵排列的自电容触控电极的图案；
其中形成的自电容触控电极包括多个公共电极；
S102、在形成有自电容触控电极图案的衬底基板上形成第一金属层的图案；
其中，形成的第一金属层包括多条与自电容触控电极一一对应的触控引线，每个自电容触控电极通过对应的触控引线与触控芯片相连；
触控引线用于在显示阶段向自电容触控电极传递公共电极信号，在触控阶段向自电容触控电极传递触控扫描信号，且将发生触控位置处的自电容触控电极产生的触控信号传输到触控芯片。
本发明实施例提供的上述自电容式触控显示面板的制备方法中，在衬底基板上形成呈矩阵排列的自电容触控电极的图案，其中形成的自电容触控电极包括多个公共电极，在形成有自电容触控电极图案的衬底基板上形成第一金属层的图案，形成的第一金属层包括多条与自电容触控电极一一对应的触控引线，每个自电容触控电极通过对应的触控引线与触控芯片相连，即通过单独设置一层第一金属层来设置触控引线，各自电容触控电极通过对应的触控引线连接至触控芯片实现触控功能。相对于现有技术在显示面板周边区域设置触控引线以实现触控功能，本发明实施例提供的上述自电容式触控显示面板单独设置一层第一金属层，可将触控引线设置在周边原有的电路图案之上，相对于现有技术不需要多余的边框位置，有利于实现窄边框设计，同时复用公共电极为自电容触控电极，将公共电极设置于由相邻棚线与相邻数据线定义的区域，这样公共电极与栅线、数据线无交叠，在触控阶段，自电容触控电极与其他信号线之间的寄生电容很小，较小的寄生电容可以保证有充足的时间进行触控驱动扫描，有利于触控驱动扫描与检测，进而有利于提高触控性能。
在具体实施时，本发明实施例提供的上述自电容式触控显示面板的制备方法中，在衬底基板上形成呈矩阵排列的自电容触控电极的图案之前或之后，还可以包括：通过一次构图工艺形成栅极、栅线和连接线的图案。

在具体实施时，本发明实施例提供的上述自电容式触控显示面板的制备方法 中，在衬底基板上形成呈矩阵排列的自电容触控电极的图案之前或之后，还可以包括：通过一次构图工艺形成栅极、栅线、连接线和第二金属层的图案。

在具体实施时，本发明实施例提供的上述自电容式触控显示面板的制备方法中，在形成有自电容触控电极图案的衬底基板上形成第一金属层的图案，可以具体包括：在形成有第一金属层的图案的衬底基板上形成源漏电极层的图案；或在形成有源漏电极层图案的衬底基板上形成第一金属层的图案。
具体地，本发明实施例提供的上述自电容式触控显示面板的制备方法中，由于第一金属层可以设置于栅极金属层与源漏电极层之间且相互绝缘，因此可以在形成栅极图案的衬底基板上形成栅绝缘层的图案，在形成栅绝缘层图案的衬底基板上形成第一金属层的图案，在形成第一金属层图案的衬底基板上形成一层绝缘层的图案，进而在形成绝缘层图案的衬底基板上形成有源层和源漏电极层的图案，或者将第一金属层设置于源漏电极层之上且相互绝缘，即在形成有源漏电极层图案的衬底基板上形成一层绝缘层的图案，在形成有绝缘层图案的衬底基板上形成第一金属层的图案，在此不作限定。
在具体实施时，本发明实施例提供的上述自电容式触控显示面板的制备方法中，还可以包括：在形成有第一金属层的图案的衬底基板上形成包括钝化层和像素电极的图案。
具体地，为了实现触控显示面板的显示与触控功能，在触控显示面板的制备过程中，还包括钝化层和像素电极层等必要功能膜层的制备，本发明实施例提供的上述自电容式触控显示面板的制备方法中，在形成第一金属层之后，还包括在形成有第一金属层的图案的衬底基板上形成包括钝化层和像素电极的图案，其制备工艺与膜层结 构与现有技术相同，在此不作详述。
具体地，经过上述实施例的描述，本发明实施例提供的上述自电容式触控显示面板的制备方法，如图6所示，可以具体包括：

基于同一发明构思，本发明实施例提供了一种本发明实施例提供的上述自电容式触控显示面板的驱动方法，如图8所示，可以具体包括以下步骤：
S201、在显示阶段，对触控显示面板中的触控引线施加公共电极信号，同时，对触控显示面板中的栅线依次施加栅扫描信号，对数据线施加数据信号；
S202、在触控阶段，对触控显示面板中的触控引线施加触控扫描信号，同时，触控显示面板中的栅线和数据线施加与触控扫描信号相调制的同步信号，且触控引线将发生触控位置处的自电容触控电极产生的触控信号传输到触控芯片，触控芯片根据触控信号确定发生触控的位置。
本发明实施例提供的上述自电容式触控显示面板的驱动方法中，在显示阶段和触控阶段对应驱动显示面板实现了显示功能和触控功能，这样触控和显示阶段采用分 时驱动方式，将公共电极复用为自电容触控电极，在显示阶段，对触控引线施加公共电极信号，为公共电极提供公共电极信号，在触控阶段，对触控引线施加触控扫描信号，驱动触控显示面板进行触控扫描，同时栅线和数据线施加与触控扫描信号相调制的同步信号，以降低自电容触控电极与其他电极线间的寄生电容，从而降低自电容触控电极与其他电极线间的RC延迟，且触控引线将发生触控位置处产生的触控信号传输到触控芯片，触控芯片根据触控信号确定触控点位置，这样融合了自电容式的内嵌触控技术，将内嵌技术与现有的大尺寸显示面板相结合，实现了低成本下大尺寸显示面板的显示和触控的优异体验，将公共电极设置于由相邻栅线与相邻数据线定义的区域，这样公共电极与栅线、数据线无交叠，在触控阶段，自电容触控电极与其他信号线之间的寄生电容很小，有利于提高触控性能。

如图11所示，触控驱动电极01包括多个公共电极2。如图9和图10所示，第一金属层包括多条与每列触控驱动电极01一一对应的触控驱动引线03，每列触控驱动电极01通过对应的触控驱动引线03与触控芯片4相连。
在显示阶段，触控驱动引线03用于向触控驱动电极01传递公共电极信号，在触控阶段，触控驱动引线03用于向触控驱动电极01传递触控扫描信号，且触控感应电极用于耦合触控扫描信号并输出耦合后的触控信号到触控芯片4，触控芯片4根据触控信号确定发生触控的位置。
本发明实施例提供的上述自电容式触控显示面板，可以包括具有呈矩阵排列的触控驱动电极01和第一金属层的阵列基板；其中，触控驱动电极01包括多个公共电极2，第一金属层包括多条与每列触控驱动电极01一一对应的触控驱动引线03，每列触控驱动电极01通过对应的触控驱动引线03与触控芯片4相连，触控驱动引线03用于在显示阶段向触控驱动电极01传递公共电极信号，在触控阶段向触控驱动电极01传递触控扫描信号，且触控感应电极用于耦合触控扫描信号并输出耦合后的触控信号到触控芯片4，触控芯片4根据触控信号确定发生触控的位置，这样互电容式触控显示面板在触控阶段复用公共电极为触控驱动电极，通过单独设置一层第一金属层，将触控驱动引线设置于第一金属层上，各列触控驱动电极通过对应的触控引线连接至触控芯片实现触控功能。相对于现有技术在显示面板周边区域设置触控引线以实 现触控功能，本发明实施例提供的互电容式触控显示面板单独设置一层第一金属层，可将触控驱动引线设置在周边原有的电路图案之上，相对于现有技术不需要多余的边框位置，有利于实现窄边框设计，同时在触控阶段复用公共电极为触控驱动电极与触控感应电极形成互电容实现触控功能。如图11所示，将公共电极2设置于由相邻栅线N与相邻数据线M定义的区域，这样公共电极2与栅线N、数据线M无交叠，在触控阶段，触控驱动电极与其他信号线之间的寄生电容很小，较小的寄生电容可以保证有充足的时间进行触控驱动扫描，有利于触控驱动扫描与检测，进而有利于提高触控性能。
在具体实施时，本发明实施例提供的上述互电容式触控显示面板中，为了实现互电容式触控显示面板在触控阶段的触控功能，因此单独设置一层第一金属层，进而可以将触控驱动引线设置于第一金属层上，这样相对于现有技术中采用增大显示面板的边框区域来设置触控驱动引线的方式，本发明实施例单独设置一层第一金属层来设置触控驱动引线可以实现触控显示面板的窄边框设计，如图12所示，在栅极金属层Gate紧邻阵列基板的衬底基板设置的情况下，用于设置触控驱动引线的第一金属层(触控驱动引线03所在位置)可以位于栅极金属层Gate和源漏电极层SD之间且三者相互绝缘，其中触控驱动引线03与触控驱动电极01相连接的位置设置有过孔U，进而通过过孔U实现触控驱动电极01与触控驱动引线03的电性连接；也可以将第一金属层设置于源漏电极层之上且相互绝缘，以实现触控驱动引线与触控驱动电极的连接，上述两者方式均可以实现将触控驱动引线设置于第一金属层上，当然也可以根据实际生产工艺和产品要求，对第一金属层的设置位置进行调整以实现触控功能，在此不作限定。
在具体实施时，本发明实施例提供的上述互电容式触控显示面板中，为了实现将各触控驱动电极连接至触控芯片，以实现触控显示面板在触控阶段的触控功能，因此各触控驱动引线将各自对应的列触控驱动电极连接至触控芯片，由于触控驱动电极呈矩阵排列的方式，如图9和图10所示，因此触控驱动引线03包括沿栅线N方向延伸的第一部分031和沿数据线M方向延伸的第二部分032，这样各触控驱动引线03与各列触控驱动电极01一一对应，通过沿栅线N延伸的第一部分031与各触控驱动电极01相连，再通过沿数据线M延伸的第二部分032连接至触控芯片，采用该连接方式时触控芯片设置于沿数据线延伸的方向上；也可以通过沿数据线延伸的第二部分与各触控驱动电极相连，再通过沿栅线延伸的第一部分连接至触控芯片，采用该连接方式时触控芯片设置于沿栅线延伸的方向上，在此不作限定。
在具体实施时，本发明实施例提供的上述互电容式触控显示面板中，如图9和图10所示，第一金属层包括：多个与触控驱动电极01一一对应的基台P，基台P设 置有过孔U，触控驱动电极01通过基台P与相应的触控驱动引线03相连。在图9中，第一金属层包括在图示的左侧的一组触控驱动引线；在图10中，第一金属层包括在图示的左右对称的两组触控驱动引线。
具体地，本发明实施例提供的上述互电容式触控显示面板中，为了实现触控驱动电极01与触控驱动引线03的连接，需要对触控驱动电极01与触控驱动引线03之间进行过孔连接，为了便于实施过孔工艺，因此在第一金属层上设置与各触控驱动电极01一一对应的基台P，这样在基台P位置便于实施过孔工艺，有助于实现触控驱动电极与触控驱动引线的良好电性连接。
在具体实施时，本发明实施例提供的上述互电容式触控显示面板中，如图11所示，触控驱动电极01包括的多个公共电极2呈矩阵排列，每个触控驱动电极01中的每行公共电极中的多个公共电极2之间通过连接线5相连，每个触控驱动电极01中相邻行的且位于同一列的公共电极2之间通过第一金属层上的跳线L连接或通过像素电极层上的跳线L连接。
具体地，本发明实施例提供的上述互电容式触控显示面板中，将公共电极复用为触控驱动电极，在触控阶段以实现触控功能，其中公共电极位于阵列基板的衬底基板上，与棚极位于同层，每个触控驱动电极包括多个公共电极，为了实现触控驱动电极的触控功能，需要将一个触控驱动电极所包含的多个公共电极连接成一个完整的触控驱动电极，这样才能实现触控驱动电极的触控功能，一般地，触控驱动电极包括的多个公共电极可以呈矩阵排列，因此可以将每个触控驱动电极中的每行公共电极中的多个公共电极之间通过连接线相连，每个触控驱动电极中相邻行的公共电极之间通过第一金属层上的跳线连接或通过像素电极层上的跳线连接，这样利用阵列基板中现有金属膜层，例如第一金属层或者像素电极层，当然也可以是其他可以设置跳线以连接相邻行公共电极的金属层，这样将相邻行公共电极通过其他金属层设置的跳线连接，避免与栅线形成交叉短路，可以实现一个自电容触控电极包含的各个公共电极连接为一个整体，进而实现自电容触控电极的触控功能，同时利用现有金属膜层设置跳线，可以简化阵列基板的制作工艺，简化膜层结构，降低生产成本。
在具体实施时，本发明实施例提供的上述互电容式触控显示面板中，用于连接每个触控驱动电极中的每行公共电极中的多个公共电极之间的连接线与栅线同层设置且相互平行。
具体地，本发明实施例提供的上述互电容式触控显示面板中，公共电极位于衬底基板上可与栅极同层设置，因此用于连接每个触控驱动电极中的每行公共电极中的 多个公共电极之间的连接线可以与栅线同层设置且相互平行，这样在阵列基板制作过程中，可以采用同一次构图工艺形成栅极、栅线、连接线，这样可以简化制作工艺、降低生产成本。
在具体实施时，本发明实施例提供的上述互电容式触控显示面板中，还可以包括：第二金属层，该第二金属层与栅极金属层同层设置且与第一金属层并联设置。
具体地，本发明实施例提供的上述互电容式触控显示面板中，为了提高触控显示面板的驱动频率，可以进一步降低第一金属层上的触控驱动引线的电阻，即通过在栅极金属层设置第二金属层，第二金属层的图案设置成多个公共电极的形状，与第一金属层上的触控驱动引线平行设置，第二金属层包括的公共电极与栅极可同一次构图工艺形成，且第二金属层包括的公共电极在相应的位置通过过孔与第一金属层上的触控驱动引线连接形成并联设置，这样可以实现第一金属层与第二金属层的并联设置，从而可以降低第一金属层的电阻，其触控显示面板的触控驱动频率可以大约提高30％。
在具体实施时，本发明实施例提供的上述互电容式触控显示面板中，如图10所示，为了提高触控显示面板的触控驱动频率，可以将第一金属层设置成包括左右对称的两组触控驱动引线03，每列触控驱动电极01对应两条触控驱动引线03，这样触控显示面板在触控阶段可以实现双边驱动，进而可以提高触控扫描的频率，进一步提高触控性能。
在具体实施时，本发明实施例提供的上述互电容式触控显示面板中，如图13所示，将一列触控驱动电极01连接到同一条触控驱动引线03，以列为单位实现触控驱动扫描，在相邻的两行触控驱动电极01之间设置有公共电极2，位于彩膜基板上的触控感应电极02与公共电极2对应设置且相互平行，这样横向设置的触控感应电极02与纵向设置的触控驱动电极列之间形成互电容以实现触控功能，其中，触控感应电极02与触控驱动电极01之间无交叠，这样二者之间形成的寄生电容很小，在发生触控时触控感应电极与触控驱动电极之间的互电容变化比较明显，易于检测到发生触控位置处产生的触控信号，进而易于对发生触控位置处的检测与确定，具体地，如图14所示，互容式触控显示面板包括具有触控驱动电极01的阵列基板和具有触控感应电极02的彩膜基板，横向设置的触控感应电极02与纵向设置的触控驱动电极列之间形成互电容以实现触控功能。

在具体实施时，本发明实施例提供的上述互电容式触控显示面板的制备方法中，在衬底基板上形成呈矩阵排列的触控驱动电极的图案之前或之后，还可以包括：通过一次构图工艺形成栅极、栅线、连接线和第二金属层的图案。
