随着显示技术的飞速发展，触控屏(Touch Panel，简称TP)的诞生使人们的生活更加便捷。
触控屏包括外挂式电容触控屏(Add On Touch Panel)和内嵌式电容触控屏(In Cell Touch Panel)，其中，对于内嵌式电容触控屏，触控电极集成在显示面板内部，通常设置在显示面板的阵列基板内部。
目前，对于内嵌式电容触控屏，如图1所示，其阵列基板01上的第一触控电极10与第一触控电极走线20相连，第二触控电极30与第二触控电极走线40相连；其中，第一触控电极10、第二触控电极30、第一触控电极走线20和第二触控电极走线40均位于显示区域的透光区。由于第一触控电极10、第二触控电极30、第一触控电极走线20和第二触控电极走线40需要占用透光区的面积，因此会导致开口率下降。

具体实施方式
下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
除非另作定义，此处使用的技术术语或者科学术语应当为本领域技术人员所理解的通常意义。本发明专利申请说明书以及权利要求书中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明。术语“多个”指两个或两个以上，除非另有明确的限定。
根据本发明的实施例，提供了一种触控显示面板，该触控显示面板包括：第一触控电极、第二触控电极、第一触控电极走线和第二触控电极走线；所述第一触控电极走线和所述第二触控电极走线交叉设置，用于根据所述第一触控电极和所述第二触控电极之间电容的变化确定触控位置。
如图2、图4、图6a和图6b所示，所述第一触控电极10设置于所述触控显示面板的阵列基板01上；如图3、图5和图7所示，所述第二触控电极30和与其相连的第二触控电极走线40设置于所述触控显示面板的对盒基板02上，且沿垂直所述触控显示面板的方向，所述第二触控电极30与所述第一触控电极10的投影重叠；所述第一触控电极走线20设置于所述阵列基板01或所述对盒基板02上。
需要说明的是，第一，根据本发明的实施例，实现触控位置识别的原理为：当没有触控发生时，所述第一触控电极10和第二触控电极30之间的电容固定不变；当有触控发生时，所述第一触控电极10和第二触控电极30之间的电容相对没有触控发生时，二者之间的电容发生变化，从而根据与该第一触控电极10和第二触控电极30对应的第一触控电极走线20和第 二触控电极走线40确定触控位置。
基于此，在通过所述第一触控电极走线20和所述第二触控电极走线40确定触控位置的基础上，所述第一触控电极走线20有如下两种设置方式：
第一种：如图2和图4所示，第一触控电极走线20设置在阵列基板01上。
在此基础上，要通过第一触控电极走线20和第二触控电极走线40实现触控位置的识别，所述第一触控电极走线20则需与第一触控电极10相连。这样，当位于阵列基板01上的第一触控电极10和位于对盒基板02上的第二触控电极30之间的电容发生变化时，通过与第一触控电极10和第二触控电极30分别相连的第一触控电极走线20和第二触控电极走线40便可确定触控位置。
第二种，如图7所示，第一触控电极走线20设置在对盒基板02上。
在此基础上，要通过第一触控电极走线20和第二触控电极走线40实现触控位置的识别，所述第一触控电极走线20则需与第二触控电极30相连。这样，当位于阵列基板01上的第一触控电极10和位于对盒基板02上的第二触控电极30之间的电容发生变化时，通过与第二触控电极30都相连的第一触控电极走线20和第二触控电极走线40才可以确定触控位置。
第二，根据本发明的示例性实施例，所述触控显示面板可以为液晶型显示面板，也可以为有机电致发光型显示面板，具体在此不做限定。
不管是液晶型显示面板还是有机电致发光型显示面板，如图2、图4、图6a和图6b所示，其中的阵列基板01都可以包括阵列排布的多个子像素，每个子像素可包括薄膜晶体管70。
在此基础上，对于液晶型显示面板，其阵列基板01的子像素还包括与薄膜晶体管70的漏极相连的像素电极，进一步的还可以包括公共电极。其中，所述像素电极和所述公共电极可以同层间隔设置且均为条状电极，或者所述像素电极和所述公共电极不同层设置，在上的电极为条状电极，在下的电极为板状电极。对于有机电致发光型显示面板，其阵列基板01的子 像素还包括与薄膜晶体管70的漏极相连的阳极、以及位于阳极上方的有机发光层和阴极。
当然，所述阵列基板01还包括与所述薄膜晶体管70的栅极相连的栅线50和与薄膜晶体管70的源极相连的数据线60。
对于液晶型显示面板，如图3、图5和图7所示，其对盒基板02还可以包括彩色膜层R、彩色膜层G、彩色膜层B和黑矩阵80。对于有机电致发光型显示面板，其对盒基板02为封装基板。
第三，不对所述第一触控电极10、第二触控电极30、第一触控电极走线20和第二触控电极走线40在各自基板上的具体设置位置进行限定，以能实现触控位置的识别为准。
第四，由于本发明的实施例为电容触控，因此，所述第一触控电极10和第二触控电极30的材料均为透明导电材料，例如ITO(氧化铟锡)、IZO(氧化铟锌)等。在此基础上，由于第二触控电极走线40和第二触控电极30相连，为了简化工艺，本领域技术人员通常会将第二触控电极走线40的材料也设置为透明导电材料，以便可以通过同一次构图工艺形成第二触控电极走线40和第二触控电极30。
在此基础上，当所述第一触控电极走线20也设置在对盒基板02上时，根据本发明的实施例，所述第一触控电极走线20也可采用透明导电材料制备。
当所述第一触控电极走线20设置在阵列基板01上时，不对其材料进行限定，可以为透明导电材料，也可以为金属材料，具体根据实际情况进行设定。
根据本发明实施例，提供了一种触控显示面板，由于第二触控电极走线40，或者第二触控电极走线40和第一触控电极走线20设置在对盒基板02上，也就是说，在阵列基板01上最多设置第一触控电极10和第一触控电极走线20，因而，相对现有技术中阵列基板上设置第一触控电极10、第二触控电极30、第一触控电极走线20和第二触控电极走线40，本发明实施例可以提高开口率。
根据本发明的实施例，如图8所示，所述对盒基板02可包括辅助隔垫物90；所述第二触控电极30设置于所述辅助隔垫物90靠近所述阵列基板01一侧。
需要说明的是，第一，本领域技术人员都知道，对于支撑盒厚的隔垫物，一般包括主隔垫物和辅助隔垫物两类，本发明实施例中的主隔垫物可根据目前的方式进行设定，在此不做限定。
第二，本发明实施例的附图8仅是以图7的情况为例得到的A-A向剖视图，但本发明实施例并不限于此，将第二触控电极30设置于所述辅助隔垫物90靠近所述阵列基板01一侧也适用于其他情况。
本发明实施例中，由于辅助隔垫物90靠近所述阵列基板01，使得第一触控电极10和第二触控电极30之间的距离较近，二者之间的电容相对也较大，当有触控发生时，二者之间的电容变化也更为灵敏，从而可以使识别到的触控位置更为精确。
此外，由于辅助隔垫物90设置在非子像素区域，当将第二触控电极30设置于所述辅助隔垫物90靠近所述阵列基板01一侧时，与第二触控电极30对应的设置在阵列基板01上的第一触控电极10则相应的也设置在非子像素区域，这样可以避免第一触控电极10对开口率的影响，从而可以进一步提高开口率。其中，由于所述触控显示面板中只有每个子像素的区域能透光，因此，本发明实施例中，非子像素区是指除子像素的区域以外的其他区域。例如任意相邻子像素之间的区域。
当所述第一触控电极走线20设置于所述阵列基板01上且与所述第一触控电极10相连时，如图4所示，所述第一触控电极走线20可与所述阵列基板01上的数据线60平行设置，且相对所述阵列基板01的任意一行子像素，与第一触控电极走线20相邻的两根所述数据线60之间具有两个子像素，一根所述第一触控电极走线20位于所述两个子像素之间。
通过合理设置子像素和数据线60的排列方式，可以将所述第一触控电极走线20设置在非子像素区域，这样，当所述第一触控电极走线20设置在阵列基板01上时，可以避免所述第一触控电极走线20对开口率的影响， 从而可以进一步提高开口率。
根据本发明的示例性实施例，所述第一触控电极走线20与所述数据线60同层设置。这样，可减少构图工艺次数。
在此基础上，由于第一触控电极10的材料为透明导电材料，而第一触控电极走线20的材料为金属材料，因此，所述第一触控电极10与第一触控电极走线20需通过过孔电连接。
如图7所示，当所述第一触控电极走线20设置于所述对盒基板02上且与所述第二触控电极30相连时，如图6a和6b所示，所述阵列基板01还包括设置于所述栅线50靠近所述对盒基板02一侧的第一有源层101、第一源极102和第一漏极103、以及与所述第一源极相连的信号线100；其中，所述第一漏极103为所述第一触控电极10。
一方面，由于栅线50、第一有源层101、第一源极102和第一漏极103(也即第一触控电极10)可以构成薄膜晶体管，因而使得通过信号线100提供到第一漏极103(也即第一触控电极10)的电压可以保持，从而更有利于触控位置的识别。
另一方面，将第一触控电极走线20和第二触控电极走线40设置在对盒基板02上，可以避免对开口率的影响；并且，由于对盒基板02上布线较少，且针对任一个第二触控电极30，第一触控电极走线20和第二触控电极走线40电联接，因而可改善二者之间出现串扰而使触控位置的识别不精确。
根据本发明的示例性实施例，由于设置在所述阵列基板01子像素区的薄膜晶体管70包括栅极701、第二有源层(图中未标识出)、第二源极702和第二漏极703，其中所述第二源极702与数据线60相连且同层设置。基于此，根据本发明实施例，所述第一有源层101和所述第二有源层同层设置，所述信号线100与所述数据线60平行设置，且所述第一源极102、所述第一漏极103(也即第一触控电极10)以及所述信号线100与所述第二源极702、所述第二漏极703以及所述数据线60同层设置。这样，可以减少构图工艺次数。
根据本发明的示例性实施例，如图6b所示，相对所述阵列基板01的任意一行子像素，与信号线100相邻的两根所述数据线60之间具有两个子像素，一根所述信号线100位于所述两个子像素之间。这样可以避免信号线100对开口率的影响。
根据本发明的示例性实施例，如图8所示，所述第二触控电极30与所述第二触控电极走线40同层设置，与所述第一触控电极走线20之间设置有机绝缘层110。
由于有机绝缘层110可以做的较厚，因而可避免第一触控电极走线20与其他非电联接的第二触控电极走线40之间产生干扰而使识别的触控位置不准确。
本发明实施例还提供一种触控显示面板的制备方法，所述触控显示面板包括阵列基板01和对盒基板02。
如图6a和图6b所示，所述阵列基板01包括设置于子像素区的薄膜晶体管70，所述薄膜晶体管包括栅极701、第二有源层(图中未标识出)、第二源极702和第二漏极703；其中，所述栅极701与栅线50相连，所述第二源极702与数据线60相连。在此基础上还包括所述栅线50靠近所述对盒基板02一侧的第一有源层101、第一源极102和第一漏极103、以及与所述第一源极102相连的信号线100；其中，所述第一漏极103为所述第一触控电极10。
如图7所示，所述对盒基板02包括彩色膜层R、彩色膜层G、彩色膜层B和黑矩阵80。所述对盒基板02还包括：第二触控电极30、第二触控电极走线40、第一触控电极走线20，第二触控电极走线40和第一触控电极走线20均与所述第二触控电极30电联接；其中，沿垂直所述触控显示面板的方向，所述第一触控电极10和所述第二触控电极30的投影重叠。
基于此，如图9a所示，所述阵列基板01的制备方法可以包括如下步骤：
S10、通过一次构图工艺形成栅线50、栅极701，并形成栅极绝缘层；
S11、通过一次构图工艺形成位于所述栅线50上方的第一有源层101、 位于所述栅极701上方的第二有源层；以及
S12、通过一次构图工艺形成位于所述第一有源层101上方的第一源极102和第一漏极103、位于所述第二有源层上方的第二源极702和第二漏极703、还形成与所述第一源极102相连的信号线100、以及与所述第二源极702相连的数据线60。
如图9b所示，对盒基板02的制备方法包括：
S20、通过一次构图工艺形成第二触控电极30和第二触控电极走线40，并形成有机绝缘层110；以及
S21、通过一次构图工艺形成第一触控电极走线20。
基于上述，根据本发明的示例性实施例，所述对盒基板02的制备方法还包括形成辅助隔垫物90；其中，所述第二触控电极30形成于所述辅助隔垫物90靠近所述阵列基板01一侧。
本发明实施还提供了一种触控显示面板的驱动方法，所述触控显示面板包括阵列基板01和对盒基板02。
如图6a和图6b所示，所述阵列基板01包括设置于子像素区的薄膜晶体管70，所述薄膜晶体管包括栅极701、第二有源层(图中未标识出)、第二源极702和第二漏极703；其中，所述栅极701与栅线50相连，所述第二源极702与数据线60相连。在此基础上还包括所述栅线50靠近所述对盒基板02一侧的第一有源层101、第一源极102和第一漏极103、以及与所述第一源极102相连的信号线100；其中，所述第一漏极103为所述第一触控电极10。
如图7所示，所述对盒基板02包括彩色膜层R、彩色膜层G、彩色膜层B和黑矩阵80。所述对盒基板02还包括：第二触控电极30、第二触控电极走线40、第一触控电极走线20，第二触控电极走线40和第一触控电极走线20均与所述第二触控电极30电联接；其中，沿垂直所述触控显示面板的方向，所述第一触控电极10和所述第二触控电极30的投影重叠。
基于此，如图10所示，所述触控显示面板的驱动方法包括如下步骤：
S30、依次向阵列基板01上的栅线50输入扫描信号，并向信号线100输入驱动信号；以及
S31、通过位于对盒基板02上与第二触控电极30均相连的第一触控电极走线20和第二触控电极走线40上信号的变化，确定触控位置。
即：在触控时，第二触控电极30与第一触控电极10之间的电容发生变化，从而使第一触控电极走线20和第二触控电极走线40上信号发生变化，进而据此可以确定触控位置。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所述权利要求的保护范围为准。
