Abstract

一种显示面板、其制作方法及显示装置，显示面板包括排列成多行和多列的多个子像素，在每相邻的两行子像素中，位于一行中的子像素与位于另一行的子像素在列方向上分别错开；并且在每行子像素中，每个子像素与相邻的子像素的颜色不相同。多条触控信号线（009）设置于子像素之间的间隙中。触控检测电极分别用做像素结构中的子像素的公共电极层（007）；并且触控信号线（009）分别设置在位于公共电极层（007）与像素结构中的子像素的像素电极（011）之间的膜层内。通过将触控信号线（009）和数据线（005）分别设置在不同的膜层上，不会影响显示面板的开口率，也不会造成子像素之间因设置触控信号线（009）而引起的光效环境差异。数据线（005）与触控信号线（009）位于不同的膜层中，可以避免两者之间出现短路。

Description

显示面板、其制作方法及显示装置 技术领域
本发明涉及显示技术领域，尤其涉及一种显示面板、其制作方法及显示装置。
背景技术
目前，随着对于显示屏显示精度要求的提高，渲染技术(rendering technology)目前越来越广泛地应用于显示屏中。渲染技术通过像素之间的借调关系而达成更好的显示效果。同时，触控技术已广泛引入显示屏中，尤其是将触控检测电极内嵌在显示屏内部的内嵌式触摸屏，可以减薄显示屏的模组整体的厚度，又可以显著降低触摸屏的制作成本。
目前，在现有的内嵌式触摸屏中，为了满足触控精度，一般需要在显示面板内部设置几百个触控检测电极，各触控检测电极均需要设置对应的信号连接线，即触控信号线。若触控信号线从显示面板的左右两端引出，则不利于窄边框的设计。因此，一般采用双数据线方案，即利用数据线所在膜层，在纵向上增加一触控信号线。但额外引入的触控信号线势必会对显示的开口率造成影响，尤其是在高精度(PPI)的显示屏产品中影响尤甚。而且，由于触控精度要远远小于显示精度，因此，触控信号线的数量会小于数据线的数量。在设置触控信号线的子像素与未设置触控信号线的子像素的光效环境会不同，会对显示效果造成不良影响。
在采用渲染技术的显示面板中，由于每相邻的两行子像素中各子像素之间在列方向上会错开不到一个子像素的位置，因此，数据线为折线。采用双数据线方案来设置触控信号线时，容易出现数据线与触控信号线之间的短路问题。
发明内容
有鉴于此，本发明实施例提供了一种显示面板、其制作方法及显示装置，可以避免采用渲染技术的显示面板中数据线和触控信号线出现短路的问题。
根据本发明一个方面的实施例，提供一种显示面板，包括：
排列成多行和多列的多个子像素，在每相邻的两行所述子像素中，位于一行中的所述子像素与位于另一行的子像素在列方向上分别错开；并且在每行所述子像素中，每个所述子像素与相邻的子像素的颜色不相同；

根据本发明另一个方面的实施例，提供一种显示装置，包括上述任一实施例所述的显示面板。
根据本发明再一个方面的实施例，提供一种制作上述任一实施例所述的显示面板的方法，包括如下步骤：
在基板上依次形成栅极、栅绝缘层、有源层、源漏极数据线、树脂层、公共电极层、第一绝缘层、触控信号线、第二绝缘层和像素电极的图形；或，

具体实施方式
下面结合附图，对本发明实施例提供的显示面板、其制作方法及显示装置的具体实施方式进行详细地说明。
虽然将参照含有本发明的较佳实施例的附图充分描述本发明，但在此描述之前应了解本领域的普通技术人员可修改本文中所描述的发明，同时获得本发明的技术效果。因此，须了解以上的描述对本领域的普通技术人员而言为一广泛的揭示，且其内容不在于限制本发明所描述的示例性实施例。附图中各膜层的形状和大小不反映显示面板的真实比例，目的只是示意说明本发明内容。
根据本发明实施例的总体上的发明构思，提供一种显示面板，包括：由紧密排列成多行和多列的子像素构成的如图1所示的像素结构；在每相邻的两行子像素中，位于一行中的子像素与位于另一行的子像素在列方向上分别错开X个子像素的宽度，0＜X＜1，例如错开半个子像素的宽度；并且在每行所述子像素中，每个子像素与相邻的子像素的颜色不相同；
在子像素之间的列间隙中沿列方向延伸的多条数据线S1、S2......S6；
设置于子像素之间的间隙中的多条触控信号线；以及
与触控信号线电连接的多个触控检测电极；其中，
触控检测电极分别用做像素结构中的子像素的公共电极层；并且触控信号 线分别设置在位于公共电极层与像素结构中的子像素的像素电极之间的膜层内。
在显示纯色画面时，为降低功耗，可以将数据线设置为一条数据线并连接具有一种颜色的子像素，这样一条数据线与位于不同行的位于该数据线左右两侧的子像素连接，如图2所示。此时，如果采用双数据线方案来设置触控信号线，如图3所示，数据线S1和触控信号线Tx1会出现短路(图3中圆圈所示)的情况，因此，不适用在数据线所在的膜层上设置触控信号线。
根据本发明实施例的上述显示面板采用了渲染技术，如图1和6所示，每个子像素与相邻的子像素的颜色不相同，也就是说，在列方向上至少部分对齐的两个相邻的子像素的颜色不相同，位于同一行的相邻两个子像素的颜色也不相同。这种显示面板与驱动电路(UC)结合，通过虚拟算法，可以提高显示面板的显示效果。例如，利用位于同一行中的两个相邻的子像素(例如B像素和R像素)可以实现一个像素的显示效果；而传统显示面板中，由位于同一行中的三个相邻的子像素(例如B像素、R像素、G像素)实现一个像素的显示效果。
进一步地，在采用渲染技术的显示面板的基础上，利用子像素之间的间隙，设置与数据线处于不同层的触控信号线。通过将触控信号线和数据线设置在不同的膜层上，不会影响显示面板的开口率，也不会造成子像素之间因设置触控信号线而引起的光效环境差异。并且，由于数据线与触控信号线位于不同的膜层中，可以避免利用数据线所在膜层设置触控信号线时数据线和触控信号线之间出现短路。
在本发明实施例的上述显示面板中，触控检测电极分别组成像素结构中子像素的公共电极层，可以简化显示面板的结构。采用公共电极层复用触控检测电极的功能，可以在不额外增加显示面板中的膜层的数量的情况下，实现了触控功能。
基于采用公共电极层复用触控检测电极的发明构思，在本发明实施例的上 述显示面板中，如图4a所示，将触控信号线009设置于位于公共电极层007与像素电极011之间的膜层中并通过形成在第一绝缘层008中的过孔与公共电极层007电连接。这样，触控信号线009与数据线005之间存在厚度为
Figure PCTCN2017080911-appb-000001
左右的树脂层006和第一绝缘层008，使得触控信号线009与数据线005之间的电容较小，即触控信号线009对数据线005的延迟(loading)影响很小。另一方面，触控信号线009与公共电极层007之间仅存在厚度为的第一绝缘层008，触控信号线009对交叠的未连接的其他触控检测电极会存在一定的影响。
进一步地，在本发明实施例的上述显示面板中，子像素的像素电极与公共电极层之间的相对位置可以设置成如图4a所示，即在显示基板的厚度方向上像素电极011位于公共电极层007的上方。此时，公共电极层007可以屏蔽数据线产生的电场对像素电极011的干扰，不易发生串扰(Crosstalk)。在另一种实施例中，子像素的像素电极011与公共电极层007之间的相对位置也可以设置成如图4b所示，即在显示基板的厚度方向上像素电极011位于公共电极层007的下方，相对于图4a所示的像素电极011设置在公共电极层上方的实施例，图4b所示的实施例的像素结构在制作时可以减少一次掩膜。
为了使得具有窄边框的显示装置避免触控信号线从显示面板的左右两端引出，在本发明实施例的上述显示面板中，如图5所示，一般将触控信号线Tx与数据线S的延伸方向设计成分别一致，即将触控信号线Tx设置成在子像素之间的列间隙中在列方向上延伸。
进一步地，为了不会影响显示面板的开口率，在本发明实施例提供的上述显示面板中，如图5所示，位于相同两列子像素之间的列间隙内的数据线S在所述显示面板的厚度方向上的正投影一般覆盖触控信号线Tx的正投影，即触控信号线Tx的线宽一般不大于数据线S的线宽。例如，将触控信号线Tx的线宽设置为与数据线S的线宽相互重叠。
进一步地，在本发明实施例提供的上述显示面板中，由于触控操作的精度 远小于显示精度，因此，触控检测电极的数量远小于子像素的数量。在触控信号线与触控检测电极一一对应时，会存在未设置触控信号线的子像素间隙。为了保证显示面板中整体布线均匀并达到显示效果均一的目的，如图5所示，可以在除了设置有触控信号线Tx以外的两列子像素之间的列间隙处，设置与数据线S的延伸方向分别一致的浮空触控信号线Dummy Tx。
同样，为了不会影响显示面板的开口率，在本发明实施例提供的上述显示面板中，如图5所示，位于相同两列子像素之间的列间隙内的数据线S在所述显示面板的厚度方向上的正投影覆盖浮空触控信号线Dummy Tx的正投影。即浮空触控信号线Dummy Tx的线宽一般不大于数据线S的线宽。例如，将浮空触控信号线Dummy Tx的线宽设置为与数据线S的线宽相互重叠。
进一步地，为了便于像素结构的设计，在本发明实施例提供的上述显示面板中，间隔行子像素中各子像素在列方向上一般对齐排列，即奇数行子像素对齐排列，偶数行子像素对齐排列。也就是说，在依次布置的第一、第二和第三所述子像素中，第一行的所述子像素和第三行的所述子像素在列方向上分别对齐排列。
本发明实施例提供的上述显示面板中，数据线与各子像素之间可以采用列反转(Column-inversion)的连接方式，即每条数据线与位于该数据线同一侧的各子像素的像素开关连接，此时，如图6所示，每条数据线S1、S2......S6至少连接了两种颜色的子像素。在显示纯色画面时，需要开启多条与显示的纯色相连的数据线，例如需要显示红色画面时，则需要开启S1、S2、S4和S5四条数据线。
本发明另一实施例的上述显示面板中，数据线与各子像素之间可以采用Z形反转(Z-inversion)的连接方式。如图1所示，每条数据线S1、S2......S6仅与具有同一颜色且位于该数据线不同侧的子像素的像素开关连接。这样，在显示纯色画面时，仅需要开启与显示的纯色相连的数据线，例如需要显示红色画面时，则仅需要开启S1和S4两条数据线，从而可以降低功耗。
基于同一发明构思，根据本发明另一方面的实施例，还提供了一种上述显示面板的制作方法，如图4a所示，在公共电极层位于像素电极下方时，包括以下步骤：
在基板001上依次形成栅极002、栅绝缘层003、有源层004、数据线005、树脂层006、公共电极层007、第一绝缘层008、触控信号线009、第二绝缘层010和像素电极011的图形，这样，可以采用10次构图完成显示面板的制作。
根据本发明再进一步方面的实施例，提供了一种上述显示面板的制作方法，如图4b所示，在公共电极层位于像素电极上方时，包括以下步骤：
在基板001上依次形成栅极002、栅绝缘层003、有源层004、数据线005、树脂层006、像素电极011、与像素电极011绝缘的触控信号线009、第一绝缘层008和公共电极层007的图形，这样，可以采用9次构图完成显示面板的制作。
根据本发明更进一步发明的实施例，提供了一种显示装置，包括本发明实施例提供的上述显示面板，该显示装置可以为：手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。该显示装置的实施可以参见上述显示面板的实施例，重复之处不再赘述。
本发明实施例提供的上述显示面板、其制作方法及显示装置，在采用渲染技术显示面板内，由紧密排列多行和多列的子像素构成像素结构；每行子像素中各子像素对齐排列；在每相邻的两行所述子像素中，位于一行中的所述子像素与位于另一行的子像素在列方向上分别错开错开X个子像素的宽度，其中0＜X＜1，每个子像素与相邻的各子像素的颜色不相同。在此基础上，所述触控检测电极用做所述子像素的公共电极层，并且所述触控信号线设置在位于所述公共电极层与所述子像素的像素电极之间的膜层内。也就是说，利用两行子像素之间的间隙，设置与数据线异层的触控信号线，触控信号线设置在像素电极和公共电极层之间，并且和复用作为触控检测电极的公共电极层通过设置在绝 缘层中的过孔电连接。通过将触控信号线与数据线异层分别设置在不同的膜层上，不会影响显示面板的开口率，也不会造成子像素之间因设置触控信号线而引起的光效环境差异。并且，由于数据线与触控信号线位于不同的膜层中，可以避免两者之间出现短路。
显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
