技术领域
本发明的示例性实施例涉及一种阵列基板及其驱动方法、制作方法及相应的显示装置。
背景技术
现有的触控显示装置分为内嵌式(in cell)和外挂式(on cell)两种，其中内嵌式触控显示装置一般复用显示面板中的电极作为触控发射电极进行触控。这样不但降低了显示装置的整体盒厚，还减少了一道单独制作触控发射电极的工艺，因此内嵌式触控显示装置成为逐渐成为主流。

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。
在本发明的描述中，需要说明的是，术语“上”、“下”、“顶”、“底”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和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
此外，在本发明中，术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示相对重要性。术语“多个”指两个或两个以上，除非另有明确的限定。
根据本发明的示例性实施例，提供了一种阵列基板以及对该阵列基板的驱动方法，该阵列基板包括：
基底、形成在所述基底上的像素开关阵列、栅极扫描线图形和数据线图形，并具有数据信号接入端和触控发射信号接入端；
该阵列基板还包括：形成在所述基底上的显示/触控转换开关阵列和转换控制信号线；其中所述显示/触控转换开关阵列与所述数据线图形中的多列数据线以及所述转换控制信号线相耦接，适于在所述转换控制信号线的控制下，使所述多列数据线在显示阶段耦接数据信号接入端，在触控阶段作为触控发射电极耦接触控发射信号接入端。
根据本发明的示例性实施例，对上述的阵列基板进行驱动的方法可以包括：
在显示阶段，在所述转换控制信号线上施加控制信号，以使所述 显示/触控转换开关阵列将所述多列数据线耦接到所述数据信号接入端；以及
在触控阶段，在所述转换控制信号线上施加控制信号，以使所述显示/触控转换开关阵列将所述多列数据线耦接到触控发射信号接入端。
根据本发明示例性实施例提供的阵列基板及其驱动方法中，分时复用数据线，即数据线在显示阶段作为数据线接收数据信号，从而实现图像显示；在触控阶段作为触控发射电极，从而实现触控检测。由于数据线一般在列方向上贯穿整个显示区域，因此不需要再制作触控发射电极线，降低了制作难度。或者，即使受限于触控发射信号接入端的数量需要制作一定长度的触控发射电极线，由于数据线一般也需要采用金属材料制作，则可以与触控发射电极线在同一工艺中形成，同样能够降低制作难度。
在某些示例性实施例中，为了避免在触控阶段将数据信号写入到像素中，还可以在触控阶段将像素开关阵列中的各个像素开关关断，从而避免下一帧的发光显示。
根据本发明的其它示例性实施例，还提供了一种显示装置，该显示装置除了包括上述的阵列基板之外，还可包括彩膜基板。
根据本发明的示例性实施例，该彩膜基板可以包括衬底以及形成在衬底上的公共电极图形，所述公共电极图形包括多个公共电极块和触控接收电极线；位于同一行的各个公共电极块适于作为一个触控接收电极耦接到同一触控电极接收线。通过复用彩膜基板中的公共电极作为触控接收电极线，从而能够进一步降低盒厚和制作难度。
本申请在触控阶段可将各数据线均作为触控发射电极线，也可以将部分数据线作为触控发射电极线，这可以根据触控精度大小需求而设置。
下面结合附图对本发明的示例性实施例提供的阵列基板的结构及其驱动方法、包含该阵列基板的显示装置的结构进行说明。
以在触控阶段将部分数据线作为触控发射电极线为例说明，在触控阶段作为触控发射电极线的各数据线称为复用数据线组，其余各数据线称为非复用数据线组；
参考图1，该阵列基板中的各条数据线300分为复用数据线组Y和非复用数据线组N，每一个复用数据线组Y以及每一个非复用数据线组N均包括4条数据线300；另外，该阵列基板上还形成有显示开关阵列410和触控开关阵列420、触控发射电极线600，用于控制显示开关阵列410的显示控制信号线510，以及用于控制触控开关阵列420的触控控制信号线520；
其中各个显示开关阵列410中的显示开关400的控制端均耦接显示控制信号线510，各个触控开关阵列420中的触控开关400的控制端均耦接触控控制信号线520；并且，一个显示开关阵列410以及一个触控开关阵列420与一个复用数据线组Y对应耦接，一条触控发射电极线600耦接一个触控开关阵列420。具体来说，一个显示开关阵列410中的各个显示开关400与所对应的复用数据线组Y中的各条数据线300一一对应，每一个显示开关400的第一端(上端)耦接对应的数据线300，每一个显示开关400的第二端(下端)耦接到对应的数据信号接入端；一个触控开关阵列420中的各个触控开关400与所对应的复用数据线组Y中的数据线300也一一对应，各个触控开关400的第一端(上端)耦接对应的数据线300，各个触控开关400的第二端(下端)耦接到同一触控发射电极线600，各条触控发射电极线600耦接到对应的触控发射信号接入端。
假设图1中的各个开关400在高电平时导通，在低电平时关断，则对上述的阵列基板进行驱动的方法可以参考图2，包括：
在每一帧内的显示阶段，在显示控制信号线510上施加高电平，以使各个显示开关阵列410中的各个显示开关400导通，并且在触控控制信号线520上施加低电平，以使各个触控开关阵列420中的各个触控开关400关断；
在每一帧内的触控阶段，在显示控制信号线510上施加低电平，以使各个显示开关阵列410中的各个显示开关400关断，并且在触控控制信号线520上施加高电平，以使各个触控开关阵列420中的各个触控开关400导通。
这样在显示阶段，各条数据线300被接入对应的数据信号接入端，从而用于传输数据信号；而在触控阶段，各条数据线300则被接入对应的触控发射信号接入端，从而作为触控发射电极使用，以实现触控检测。
可见，根据本发明示例性实施例提供的阵列基板能够复用数据线，从而实现触控检测，而由于数据线一般也需要采用金属材料制作，则可以与触控发射电极线在同一工艺中形成，从而能够降低制作难度。
在图1中将数据线300分为复用数据线组Y和非复用数据线组N，并仅将复用数据线组Y中的数据线300复用为触控发射电极，能够降低开关400的数量和触控发射电极线600的数量，从而进一步降低制作工艺的难度。在保证复用数据线组Y和非复用数据线组N中的数据线的数量(比如4条)不是太大的情况下，一般也均能够满足触控精度的要求。不难理解的是，在不脱离本发明的精神和范围的前提下，也可以针对每一条数据线300设置一个触控开关和一个显示开关，将全部的数据线300(包括复用数据线组Y和非复用数据线组N中的数据线300)均复用为发射电极，另外，在满足触控精度的要求的前提下，作为一个触控发射电极耦接到同一触控发射电极线600的数据线300的数量也不必然为4。
在图1中，显示开关阵列410和触控开关阵列420共同使数据线300作为数据线提供数据电压或者使数据线300复用为触控发射电极的显示/触控转换开关阵列。然而不难理解的是，上述的显示/触控转换开关阵列也可以为其他形式。
如图3所示，根据本发明示例性实施例提供的显示装置，除了包含图1中的形成在阵列基板之上的数据线之外，还包括彩膜基板，该彩膜 基板包括衬底(图中未示出)以及形成在衬底上的由多个公共电极块710构成的公共电极图形，以及耦接每行中各个公共电极块710的触控接收电极线720，一行中的各个公共电极块710耦接到一条触控接收电极线720，从而可复用为一个触控接收电极。这样由于无需单独制作触控接收电极，从而能够降低该显示装置的盒厚并简化制作工艺。
当然，在实际应用中，上述的彩膜基板还可能包括彩色滤光层，黑矩阵等结构，在此不在详细说明。
在某些示例性实施例中，上述显示装置除了包括上述的阵列基板和彩膜基板之外，还可以包括：数据驱动电路、触控驱动电路、栅极扫描电路和时序控制电路，所述数据驱动电路与所述时序控制电路的显示使能信号输出端以及所述阵列基板的数据信号接入端相耦接，用于在接收到所述时序控制电路通过所述显示使能信号输出端输出的显示使能信号时，向所述阵列基板输出数据电压；
所述栅极扫描电路与所述时序控制电路的显示使能信号输出端相耦接，用于在接收到所述时序控制电路通过所述显示使能信号输出端输出的显示使能信号时，逐行开启所述像素开关阵列中的像素开关；
所述触控驱动电路与所述时序控制电路的触控使能信号输出端以及所述阵列基板的触控发射信号接入端相耦接，用于在接收到所述时序控制电路通过所述触控使能信号输出端输出的触控使能信号时，向所述阵列基板输出触控发射信号；以及
显示控制信号线与所述显示使能信号输出端相耦接，各个显示开关适于在所述显示使能信号输出端输出的显示使能信号时导通；触控控制信号线与所述触控使能信号输出端相耦接，各个触控开关适于在所述触控使能信号输出端输出的触控使能信号时导通。
这样相当于复用了时序控制器的显示使能信号输出端以及触控使能信号输出端，从而实现对显示开关和触控开关的控制，而无需重新设计时序控制器。
在某些示例性实施例中，本发明提供的显示装置可以为手机、电 视机、台式电脑、PAD、掌上电脑等具有显示功能的装置。
根据本发明的示例性实施例，还提供了一种阵列基板的制作方法，可用于制作上述的阵列基板，该方法包括：
在基底上形成像素开关阵列、栅极扫描线图形和数据线图形，并形成数据信号接入端和触控发射信号接入端；
还包括：
在基底上形成显示/触控转换开关阵列和转换控制信号线；
其中，所述显示/触控转换开关阵列与所述数据线图形中的多列数据线以及所述转换控制信号线相耦接，适于在所述转换控制信号线的控制下，使所述多列数据线在显示阶段耦接数据信号接入端，在触控阶段作为触控发射电极耦接触控发射信号接入端。
根据本发明示例性实施例提供的制作方法所制作的阵列基板，复用数据线作为触控发射电极，从而实现触控检测。由于数据线一般在列向上贯穿整个显示区域，因此不需要再制作触控发射电极线，从而降低了制作难度。或者，即使受限于触控发射信号接入端的数量需要制作一定长度的触控发射电极线，由于数据线一般也需要采用金属材料制作，从而可以与触控发射电极线在同一工艺中形成，同样能够降低制作难度。
形成像素开关阵列、栅极扫描线图形、数据线图形，并形成数据信号接入端和触控发射信号接入端以及显示/触控转换开关阵列、转换控制信号线的具体工艺可以参考现有技术，在此不再详细说明。
根据本发明的示例性实施例，可以在形成所述像素开关阵列的同一工艺中形成所述显示/触控转换开关阵列，这样能够降低制作工艺的复杂度。
以上所述，仅为本发明的具体实施方式，但是，本发明的保护范围不局限于此，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，可轻易想到的变化或替代，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。
