Description

触控显示面板及其制作方法、触控显示装置 技术领域
本发明的实施例涉及一种触控显示面板及其制作方法、触控显示装置。
背景技术
随着显示技术的飞速发展，触控显示面板(Touch Panel)已经逐渐遍及人们的生活中。与仅能提供显示功能的传统显示器相比较，使用触控显示面板的显示器能够使得使用者与显示控制主机之间进行信息交互，因此，触控显示面板可以完全或者至少部分取代常用的输入装置，使得现有的显示器不仅能够显示，还能触控控制。目前，应用最广泛的触控显示面板为电容触控显示面板，电容触控显示面板根据与薄膜晶体管基板(Thin Film Transistor，TFT)及对置基板(Colour Filter，CF)的相对关系分为内嵌式(in-cell)、外嵌式(on-cell)及外挂式等三种。其中，内嵌式电容触控显示面板以其集成度高、薄型、性能优越等优点作为触控技术的重要发展方向。
内嵌式电容触控显示面板将触控驱动电极Tx设置在阵列基板上，将触控感应电极Rx设置在与阵列基板对应的对置基板上，触控驱动电极Tx的设置方向与触控感应电极Rx的设置方向互相垂直。图1示出了阵列基板中公共电极层的结构，公共电极层包括两部分，公共电极11作为永久的公共电极，另一部分公共电极复用为触控阶段的触控驱动电极，复用为触控驱动电极的公共电极为不连续间断分布的电极块12。在形成触控驱动电极时，每一电极块12均与栅极同层制作的金属走线通过过孔15连接，所有金属走线延伸到阵列基板的周边引线区，与同一列电极块12连接的金属走线通过周边引线区中的一条引线连接在一起，形成一触控驱动电极，其中，金属走线为图中沿水平方向分布的走线，引线为图中沿竖直方向分布的走线，如：与第一列电极块12连接的金属走线131通过周边引线区中的引线141连接形成触控驱动电极Tx1，与第二列电极块12连接的金属走线132通过周边引线区中的引线142连接形成触控驱动电极Tx2。
对于上述触控显示面板，在触控阶段，由于内侧的触控驱动电极中的金 属走线会跨过外侧触控驱动电极中的电极块，如：触控驱动电极Tx2中的金属走线132跨过触控驱动电极Tx1中的电极块12，这样对内侧的触控驱动电极进行触控扫描时，外侧的触控驱动电极会受到串扰，影响触控显示面板整体触控均一性。另外，形成触控驱动电极Tx1的引线141和形成触控驱动电极Tx2的引线142若同层制作，则会发生短路，因此，在实际制作过程中，引线141和引线142需要制作在不同层，或，引线141和引线142同层制作时，在引线141和引线142的交叉位置处需要绝缘设置。
综上所述，触控显示面板在触控阶段容易发生串扰，触控显示面板整体触控均一性较差。

具体实施方式
为了使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明作进一步地详细描述，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它实施例，都属于本发明保护的范围。
附图中各层薄膜厚度和区域大小、形状不反应各膜层的真实比例，目的只是示意说明本发明内容。
下面结合附图详细介绍本发明实施例提供的触控显示面板。
如图2所示，本发明实施例提供了一种触控显示面板，包括相对设置的阵列基板20和对置基板(图中未示出)，对置基板包括若干行方向分布的触控感应电极，触控感应电极可以设置在横向分布的黑矩阵对应的区域，也可以设置在纵向分布的黑矩阵对应的区域，本发明实施例对触控感应电极的具 体设置不做限定。
阵列基板20包括若干列方向分布的触控驱动电极201、若干行方向分布的触控驱动电极走线202和若干列方向分布的与触控驱动电极走线202绝缘设置的触控驱动电极连接线203。例如，本发明实施例中的行方向指水平方向，列方向指竖直方向，当然，在实际设计中，行方向也可以指竖直方向，列方向也可以指水平方向，只要保证所述触控感应电极与所述触控驱动电极是相互交叉(例如，相互垂直)设置，其中：
每一列触控驱动电极201包括若干触控驱动电极块2011，每一触控驱动电极块2011与一触控驱动电极走线202连接，不同列触控驱动电极块2011连接不同的触控驱动电极走线202；
每一触控驱动电极块2011包括若干间断分布的触控驱动电极单元2012，每一触控驱动电极块2011包括的触控驱动电极单元2012通过触控驱动电极连接线203电连接；
与每一触控驱动电极块2011连接的触控驱动电极走线202的正投影与该触控驱动电极块2011以外的其它触控驱动电极块2011包括的触控驱动电极单元2012在阵列基板上的正投影不重叠。
在实际设计过程中，不同行分布的触控驱动电极走线202均通过一条位于阵列基板周边引线区中的引线204引出，引线204后续与阵列基板上制作的触控驱动装置(图中未示出)连接，触控驱动装置的工作原理及具体设计在这里不做限定。
从图中可以看到，与触控驱动电极走线202连接的引线204设置在阵列基板两侧的周边引线区，当然，在实际设计中，引线204也可以设置在阵列基板一侧的周边引线区。
例如，本发明实施例图2中与第四列触控驱动电极块2011连接的触控驱动电极走线202的正投影与前三列的触控驱动电极201包括的触控驱动电极连接线203的正投影存在重叠区域205，重叠区域205的位置处会产生寄生电容，由于寄生电容的存在，对第四列的触控驱动电极201进行触控扫描时，前三列的触控驱动电极201会受到串扰。重叠区域205的重叠面积越大，产生的寄生电容也越大，寄生电容越大对第四列的触控驱动电极201进行触控扫描时，前三列的触控驱动电极201受到的串扰就越大，因此，在实际设置 中，需要将触控驱动电极走线202和触控驱动电极连接线203的宽度均设置的较窄，而触控驱动电极走线202和触控驱动电极连接线203的宽度较窄时，电阻相应的会增大，因此，触控驱动电极走线202和触控驱动电极连接线203的宽度不能设置的很小，触控驱动电极走线202和触控驱动电极连接线203的宽度需要根据实际工艺情况进行设置。
与图1所示的现有技术内侧触控驱动电极中的金属走线跨过外侧触控驱动电极中的电极块相比，本发明实施例中内侧触控驱动电极走线202并不跨过外侧触控驱动电极201包括的面积较大的触控驱动电极单元2012，因此本发明实施例对内侧的触控驱动电极进行触控扫描时，内侧的触控驱动电极对外侧的触控驱动电极产生的串扰较小，进而提高了触控显示面板的触控效果。
下面的图3和图4仅示出了本发明实施例每一列触控驱动电极在列方向上的一个触控驱动电极块2011。
例如，本发明实施例在设计与每一触控驱动电极块2011连接的触控驱动电极走线202时，为了更好的降低在触控过程中，内侧触控驱动电极对外侧触控驱动电极产生的串扰，不同触控驱动电极走线202在水平方向上的设计长度可以设计的不相等，如图3所示。与图2相比，图3中当对第四列的触控驱动电极块2011进行触控扫描时，由于与第四列触控驱动电极块2011连接的触控驱动电极走线202不跨过前三列的触控驱动电极块2011，因此，对第四列的触控驱动电极块2011进行触控扫描时，第四列的触控驱动电极块2011不对前三列的触控驱动电极块2011产生串扰。
例如，本发明实施例中每一列触控驱动电极块2011包括的触控驱动电极单元2012的大小相同，触控驱动电极单元2012的尺寸根据实际生产的需要进行设置。
为了提高制作触控驱动电极的生产效率，提高触控触控显示面板的触控均匀性，例如，本发明实施例不同列触控驱动电极块2011包括的触控驱动电极单元2012的大小相同。在实际生产过程中，可以将每一个触控驱动电极单元2012的大小设置的与阵列基板包括的亚像素单元的大小相同。
本发明实施例中每一列触控驱动电极块2011可以包括一列沿竖直方向间断分布的触控驱动电极单元2012，如图2和图3所示。在实际设计过程中，若每一个触控驱动电极单元2012的尺寸设计的较小，则每一列触控驱动电极 块2011可以包括大于一列的沿竖直方向间断分布的触控驱动电极单元2012。如图4所示，本发明实施例中每一列触控驱动电极块2011包括两列沿竖直方向间断分布的触控驱动电极单元2012。
例如，本发明实施例中的阵列基板包括衬底基板，依次位于衬底基板上的触控驱动电极、栅极线、栅极绝缘层、半导体有源层、源漏极电极、钝化层和像素电极；
所述触控驱动电极分时复用，在显示阶段，所述触控驱动电极用作公共电极，用于输入公共电极信号；
在触控阶段，所述触控驱动电极用于输入触控驱动信号。
例如，本发明实施例还可以为：位于衬底基板上的触控驱动电极包括的部分触控驱动电极单元作为永久的公共电极，即该部分触控驱动电极单元在触控阶段不接收触控驱动信号，触控驱动电极包括的其余的触控驱动电极单元在触控阶段，接收触控驱动信号。如图2所示，例如，对置基板上行方向分布的触控感应电极在阵列基板上的正投影区域对应位置处的触控驱动电极，即图中区域206中的触控驱动电极单元2012作为永久的公共电极，区域206中的触控驱动电极单元2012在触控阶段不接收触控驱动信号；其余位置处的触控驱动电极单元2012在触控阶段接收触控驱动信号。图2中仅示出了一条永久的公共电极，永久的公共电极与公共电极走线207连接，公共电极走线207与触控驱动电极走线202同层设置。例如，永久的公共电极与触控驱动电极201同层设置；例如，对同一导电膜层通过一次构图工艺即可同时形成永久的公共电极与触控驱动电极201。例如，公共电极走线207与触控驱动电极走线202同层设置；例如，对同一导电膜层通过一次构图工艺即可同时形成公共电极走线207与触控驱动电极走线202。
例如，用作触控驱动电极的公共电极分时复用，在图像显示阶段为公共电极施加实现显示图像的相应电压；在触控显示阶段，为公共电极施加触控驱动电压，实现触控功能；而在图像显示阶段和触控显示阶段，均通过公共电极走线207为永久的公共电极施加实现显示图像的相应电压。
例如，本发明实施例中触控驱动电极走线与栅极线同层设置，在实际生产过程中，对同一金属膜层通过一次构图工艺即可同时形成触控驱动电极走线和栅极线，这样，形成触控驱动电极走线时不会增加工艺过程，也不会增 加制作成本。
例如，本发明实施例中触控驱动电极连接线与像素电极同层设置，在实际生产过程中，对同一透明导电膜层通过一次构图工艺即可同时形成触控驱动电极连接线和像素电极，这样，形成触控驱动电极连接线时不会增加工艺过程，也不会增加制作成本。
例如，如图4所示，本发明实施例中触控驱动电极走线202与触控驱动电极块2011包括的部分触控驱动电极单元2012直接接触连接，直接接触连接能够降低连接电阻，同时，与图1所示的现有技术相比，直接接触连接不需要设置如图1中的过孔15，能够降低生产成本。
图5为图4中区域40位置的截面结构示意图，从图中可以看到，本发明实施例中触控驱动电极块2011包括的触控驱动电极单元2012直接设置在衬底基板50上，触控驱动电极走线202与触控驱动电极单元2012直接接触电连接。
如图4和图5所示，本发明实施例中触控驱动电极走线202和触控驱动电极连接线203之间设置有栅极绝缘层和钝化层51，触控驱动电极连接线203通过贯穿栅极绝缘层和钝化层的过孔41将每一触控驱动电极块2011包括的触控驱动电极单元2012电连接。
本发明实施例还提供了一种触控显示装置，该触控显示装置包括上述的触控显示面板，该触控显示装置可以为液晶显示器、液晶电视、有机电致发光显示OLED面板、OLED显示器、OLED电视或电子纸等触控显示装置。
下面结合附图介绍本发明实施例提供的触控显示面板的制作方法。
如图6所示，本发明实施例还提供了一种触控显示面板的制作方法，包括制作阵列基板和对置基板的方法，其中，制作对置基板的方法包括在对置基板上制作若干行方向分布的触控感应电极，制作阵列基板的方法包括：

S602、在完成上述步骤的衬底基板上制作若干行方向分布的触控驱动电极走线，每一所述触控驱动电极块与一所述触控驱动电极走线连接，不同列所述触控驱动电极块连接不同的触控驱动电极走线；与每一所述触控驱动电 极块连接的触控驱动电极走线的正投影与该触控驱动电极块以外的其它触控驱动电极块包括的触控驱动电极单元在阵列基板上的正投影不重叠；
S603、在完成上述步骤的衬底基板上制作若干列方向分布的与所述触控驱动电极走线绝缘的触控驱动电极连接线，每一所述触控驱动电极块包括的触控驱动电极单元通过所述触控驱动电极连接线电连接。
如图7所示，本发明实施例制作阵列基板的方法具体包括：
S701、在衬底基板上通过构图工艺制作若干列方向分布的触控驱动电极，所述触控驱动电极分时复用，在显示阶段，所述触控驱动电极用作公共电极，用于输入公共电极信号；在触控阶段，所述触控驱动电极用于输入触控驱动信号；
S702、在完成上述步骤的衬底基板上通过构图工艺同层制作栅极、栅极线和触控驱动电极走线，所述触控驱动电极走线和所述栅极线平行；
S703、在完成上述步骤的衬底基板上通过构图工艺依次制作栅极绝缘层、半导体有源层、源漏极电极、钝化层以及贯穿所述栅极绝缘层和所述钝化层的过孔；
S704、在完成上述步骤的衬底基板上通过构图工艺同层制作像素电极和触控驱动电极连接线，所述触控驱动电极连接线通过所述过孔将每一所述触控驱动电极块包括的触控驱动电极单元进行连接。
例如，参见图4和图5，本发明实施例首先在衬底基板50上沉积一层透明导电薄膜，之后对该透明导电薄膜采用构图工艺形成触控驱动电极，每一列触控驱动电极包括若干触控驱动电极块2011，每一触控驱动电极块2011包括若干间断分布的触控驱动电极单元2012。本发明实施例中沉积的透明导电薄膜可以为氧化铟锡(ITO)薄膜，也可以为氧化铟锌(IZO)薄膜，也可以为氧化铟锡和氧化铟锌组成的复合薄膜。本发明实施例中的构图工艺包括光刻胶的涂覆、曝光、显影、刻蚀以及刻蚀后去除光刻胶的部分或全部过程。
接着，参见图4和图5，本发明实施例在完成上述步骤的衬底基板上沉积一层金属层，之后对该金属层采用构图工艺形成栅极(图中未示出)、栅极线(图中未示出)和触控驱动电极走线202，其中，触控驱动电极走线202和栅极线平行。本发明实施例中沉积的金属层可以为金属钼(Mo)、金属铝(Al)、金属镍(Ni)等单层金属层，也可以为金属钼(Mo)、金属铝(Al)、 金属镍(Ni)等金属组成的多层金属层。
接着，参见图4，本发明实施例在完成上述步骤的衬底基板上通过构图工艺依次制作栅极绝缘层(图中未示出)、半导体有源层(图中未示出)、源漏极电极(图中未示出)、钝化层(图中未示出)以及贯穿栅极绝缘层和钝化层的过孔41。
接着，参见图4和图5，本发明实施例在完成上述步骤的衬底基板上沉积一层透明导电薄膜，之后对该透明导电薄膜采用构图工艺形成像素电极(图中未示出)和触控驱动电极连接线203，在每一触控驱动电极块中，触控驱动电极连接线203通过过孔41连接相邻的两个触控驱动电极单元2012。例如，本发明实施例形成像素电极的透明导电薄膜的材料与形成公共电极的透明导电薄膜的材料相同，当然，在实际生产过程中，二者的材料也可以不同，本发明实施例并不对公共电极和像素电极的具体材料作限定。
