具体实施方式
为了改善触控显示屏的显示品质，并提高触控显示屏的触控灵敏性，本发明实施例提供了一种彩膜基板、触控显示屏及彩膜基板的制作方法。为使本发明的目的、技术方案和优点更加清楚，以下举实施例对本发明作进一步详细说明。
本发明实施例提供的彩膜基板，包括衬底基板、触控电极、彩色树脂和黑矩阵，其中：触控电极位于衬底基板的外侧，彩色树脂和黑矩阵中的至少一者覆盖于触控电极的外侧。
彩膜基板除上述结构之外，通常还包括：位于衬底基板、触控电极、彩色树脂和黑矩阵所组成结构内侧的隔垫物，以及位于衬底基板、触控电极、彩色树脂和黑矩阵所组成结构外侧的保护层。
在本发明实施例中，所述“外侧”可以理解为背离液晶层的一侧，所述“内侧”则可以理解为靠近液晶层的一侧。所述“覆盖于触控电极的外侧”可以理解为位于触控电极的外侧并将其遮挡。
衬底基板的具体类型不限，例如可以为玻璃衬底基板、树脂衬底基板等等。触控电极可以包括驱动电极和/或探测电极，其作为实现触控功能的主要结构，通常采用透明导电材质，例如氧化铟锡ITO等等。
彩色树脂通常包括R(Red，红色)树脂、G(Green，绿色)树脂和B(Blue，蓝色)树脂，主要作用是利用滤光的方式产生红绿蓝三原色，再将红绿蓝三原色以不同的强弱比例混合，从而呈现出各种色彩，使薄膜晶体管液晶显示屏可以显示出全彩。值得一提的是，在液晶显示领域中，彩色树脂并不限于RGB(Red Green Blue，红绿蓝)三色，还可以为RGBW(Red Green Blue White，红绿蓝白)、RGBY(Red Green Blue Yellow，红绿蓝黄)和CMYK(Cyan Magenta Yellow Black，青品黄黑)等多种颜色组合。此外，本领域技术人员能够理解，尽管在本发明的实施例中使用“彩色树脂”来指代本发明中的具有滤光功能的彩色滤光片，彩色滤光片也可以由彩色光刻胶或彩色油墨等材料形成。
如图1所示，本发明第一实施例提供的彩膜基板中：
隔垫物5位于衬底基板1的内侧；
触控电极2位于衬底基板1的外侧；
彩色树脂3位于触控电极2的外侧；
黑矩阵4位于彩色树脂3的外侧；
保护层6覆盖于彩色树脂3和黑矩阵4的外侧；
其中，触控电极2一部分被彩色树脂3覆盖，一部分被彩色树脂3和黑矩阵4共同覆盖。
彩色树脂3和黑矩阵4具有挡光作用，可以使触控电极2的条纹图案从屏幕上减弱或减少，从而使视觉效果不明显，因此，该方案能够有效改善触控显示屏的显示品质。
如图2所示，本发明第二实施例提供的彩膜基板中：
隔垫物5位于衬底基板1的内侧；
触控电极2位于衬底基板1的外侧；
彩色树脂3位于触控电极2的外侧；
黑矩阵4位于彩色树脂3的外侧；
保护层6覆盖于彩色树脂3和黑矩阵4的外侧；
其中，触控电极2全部被彩色树脂3覆盖。
彩色树脂3的挡光效果虽然不及黑矩阵4，但仍然可以对触控电极2的条纹图案进行遮挡，使其从屏幕上的视觉效果减弱，因此，该方案也能够有效改善触控显示屏的显示品质。
如图3所示，本发明第三实施例提供的彩膜基板中：
隔垫物5位于衬底基板1的内侧；
触控电极2位于衬底基板1的外侧；
彩色树脂3位于触控电极2的外侧；
黑矩阵4位于彩色树脂3的外侧；
保护层6覆盖于彩色树脂3和黑矩阵4的外侧；
其中，触控电极2在相邻彩色树脂3的边界处，且被彩色树脂3和黑矩阵4共同覆盖。
黑矩阵4具有较好的挡光效果，可以对触控电极2的条纹图案进行遮挡，使其从屏幕上消除，因此，该方案能够较好的改善触控显示屏的显示品质。
在上述三个实施例中，黑矩阵和彩色树脂也可以同层设置，黑矩阵位于彩色树脂的边界处，彩色树脂和黑矩阵中的至少一者覆盖于触控电极的外侧。与上述结构的效果类似，该结构的彩膜基板可以使触控电极的条纹图案从屏幕上减弱或减少，从而提高触控显示屏的显示 品质。
如图4所示，本发明第四实施例提供的彩膜基板中：
隔垫物5位于衬底基板1的内侧；
彩色树脂3位于衬底基板1的外侧；
触控电极2位于彩色树脂3的外侧；
黑矩阵4位于触控电极2的外侧；
保护层6覆盖于彩色树脂3和黑矩阵4的外侧；
其中，触控电极2全部被黑矩阵4覆盖。
同理，采用该结构设计，由于黑矩阵4具有较好的挡光效果，可以对触控电极2的条纹图案进行遮挡，使其从屏幕上消除，因此，该方案能够较好的改善触控显示屏的显示品质。
如图5所示，本发明第五实施例提供的彩膜基板中：
彩色树脂3位于衬底基板1的内侧；
隔垫物5位于彩色树脂3的内侧；
触控电极2位于衬底基板1的外侧；
黑矩阵4位于触控电极2的外侧；
保护层6覆盖于衬底基板1和黑矩阵4的外侧；
其中，触控电极2全部被黑矩阵4覆盖。
同理，采用该结构设计，由于黑矩阵4具有较好的挡光效果，可以对触控电极2的条纹图案进行遮挡，使其从屏幕上消除，因此，该方案能够较好的改善触控显示屏的显示品质。
如图6所示，本发明第六实施例提供的彩膜基板中，黑矩阵包括第一遮挡层41和第二遮挡层42，彩膜基板的具体结构如下：
触控电极2位于衬底基板1的外侧；
第一遮挡层41覆盖于触控电极2的外侧；
保护层6覆盖于衬底基板1和第一遮挡层41的外侧；
第二遮挡层42位于衬底基板1的内侧；
彩色树脂3位于衬底基板1的内侧，并且彩色树脂3的分界区域被第二遮挡层42遮挡；
隔垫物5位于彩色树脂3的内侧。
该实施例中，第二遮挡层42的作用是遮挡杂散光，防止像素之间产生漏光。第一遮挡层41的作用是对触控电极2的条纹图案进行遮挡， 使其从屏幕上消除，因此，该方案能够较好的改善触控显示屏的显示品质。
在本发明上述各实施例的技术方案中，当彩膜基板应用于触控显示屏时，由于彩色树脂3和黑矩阵4中的至少一者覆盖于触控电极2的外侧，这样可以使触控电极2的条纹图案从屏幕上减弱或者消除，因此，该方案能够有效改善触控显示屏的显示品质。此外，由于触控电极2位于衬底基板1的外侧，触控的灵敏性不受衬底基板1厚度的影响，因此，该方案还能够提高触控显示屏的触控灵敏性。
本发明实施例还提供了一种触控显示屏，包括前述任一实施例的彩膜基板。该触控显示屏具有较佳的显示品质，并且触控灵敏性较高。
如图7所示，本发明第七实施例所提供的彩膜基板的制作方法，包括以下步骤：
步骤101、形成位于衬底基板外侧的触控电极；
步骤102、形成覆盖于触控电极外侧的彩色树脂和/或黑矩阵。
采用该方法制作的彩膜基板应用于触控显示屏时，由于彩色树脂和黑矩阵中的至少一者覆盖于触控电极的外侧，这样可以使触控电极的条纹图案从屏幕上减弱或者消除，从而有效改善触控显示屏的显示品质。此外，由于触控电极位于衬底基板的外侧，触控的灵敏性不受衬底基板厚度的影响，因此，采用该方法所制作的彩膜基板，还能够提高触控显示屏的触控灵敏性。
本发明第八实施例所提供的彩膜基板的制作方法，具体包括以下步骤：
形成位于衬底基板内侧的隔垫物；
形成位于衬底基板外侧的触控电极；
形成位于触控电极外侧的彩色树脂；
形成位于彩色树脂外侧的黑矩阵；
形成覆盖于彩色树脂和黑矩阵外侧的保护层；
其中，彩色树脂和黑矩阵中的至少一者覆盖于触控电极的外侧。
可采用本发明第八实施例所提供的制作方法制作图1至图3所示的彩膜基板。
本发明第九实施例所提供的彩膜基板的制作方法，可用于制作图4所示的彩膜基板，具体包括以下步骤：
形成位于衬底基板内侧的隔垫物；
形成位于衬底基板外侧的彩色树脂；
形成位于彩色树脂外侧的触控电极；
形成覆盖于触控电极外侧的黑矩阵；
形成覆盖于彩色树脂和黑矩阵外侧的保护层。
本发明第十实施例所提供的彩膜基板的制作方法，可用于制作图5所示的彩膜基板，具体包括以下步骤：
形成位于衬底基板内侧的彩色树脂；
形成位于彩色树脂内侧的隔垫物；
形成位于衬底基板外侧的触控电极；
形成覆盖于触控电极外侧的黑矩阵；
形成覆盖于衬底基板和黑矩阵外侧的保护层。
本发明第十一实施例所提供的彩膜基板的制作方法，可用于制作图6所示的彩膜基板，具体包括以下步骤：
形成位于衬底基板内侧的第二遮挡层；
形成位于衬底基板内侧的彩色树脂，彩色树脂的分界区域被第二遮挡层遮挡；
形成位于彩色树脂内侧的隔垫物；
形成位于衬底基板外侧的触控电极；
形成覆盖于触控电极外侧的第一遮挡层；
形成覆盖于衬底基板和第一遮挡层外侧的保护层。
第八至第十一实施例的有益效果同前，这里不再重复赘述。
此外，当触控显示屏包括阵列基板和彩膜基板时，以上各实施例的方法流程中，在形成隔垫物之后，可以先将彩膜基板与阵列基板对盒。这样可以利用阵列基板上的对位标记作为后续相关工艺的对位标记。采用统一的对位标记，对位精度较高，有利于减小黑矩阵的设计线宽，从而增大屏幕的透过率。
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。
