Description

触摸基板及其制作方法、触摸显示面板 技术领域
本发明涉及显示领域，尤其涉及一种触摸基板及其制作方法、触摸显示面板。
背景技术
现有的触摸基板根据其工作原理分为：电容式、电阻式、红外、压力传感等几种，其中电容式触摸基板应用较为广泛，其广泛应用于手机、平板等领域。
传统的电容式触摸面板，是将一层盖板玻璃与一层触控玻璃通过光学胶(OCA)贴合形成触控面板，即GG(Glass-Glass)结构，但随着触控技术的发展，该结构已不能满足触摸基板轻、薄、低成本等要求，其逐渐被GF(Glass-Film)、GFF(Glass-Film-Film)、OGS(On Glass Solution)等触控结构所取代。
目前市场上OGS相较于GG、GF、GFF等触控结构在外观方面遇到了难题。常规的GG、GF、GFF等触控结构是使用黑色油墨或白色油墨作为盖板的边框遮光材料，可以生产出黑色边框的触摸屏及白色边框的触摸屏。
然而，油墨耐高温性差，在制作OGS的高温工艺过程中，油墨容易受到高温影响而变黄，影响美观。为了美观，OGS使用白色光阻作为边框遮光材料，但是目前市场上的白色光阻还不太成熟且遮光效果差，因此，用白色光阻生产玻璃盖板要达到与白色油墨生产的盖板相同的光学效果，需要白色光阻的厚度至少要达到15um及以上，如图1及图2所示，在基板1的同一表面设置有白色光阻层2和触控电极层3，因为白色光阻层2需要一定的厚度，这样就会导致触控电极层3与白色光阻层2叠加的位置(即，爬坡位置)容易出现断线的可能，从而影响产品性能。
发明内容
本发明的实施例要解决的技术问题是如何减轻或避免触控电极在边缘区域爬坡时出现断线的问题。
为解决上述技术问题，本发明实施例的技术方案提供了一种触摸基板，包括基板、光阻层和触控电极层，所述光阻层位于所述基板的第一表面周边，所述触控电极层位于所述基板的第二表面。
进一步地，所述光阻层可包括白色光阻层。
进一步地，所述光阻层还可包括位于所述白色光阻层下方的黑色光阻层。
进一步地，所述光阻层上方还可设置有覆盖所述基板整个第一表面的第一保护层。
进一步地，所述触控电极层可以为透明导电材料制作而成。

本发明的另外的实施例还提供了一种触摸显示面板，包括上述实施例中的任一实施例所描述的触摸基板。
进一步地，所述触摸显示面板可包括显示面板和设于所述显示面板出光侧的所述触摸基板。
本发明的又一实施例还提供了一种触摸基板的制造方法，该方法可包括：提供一基板；在所述基板第一表面周边形成光阻层；在所述基板第二表面形成触控电极层。
进一步地，形成光阻层的步骤可包括：在所述基板第一表面周边形成黑色光阻层；在所述黑色光阻层上方形成白色光阻层。

进一步地，可以采用溅射或者镀膜工艺形成所述导电膜层。
本发明实施例提供的触摸基板，通过将光阻层与触控电极层做在基板的不同表面，可以规避触控电极层在基板边缘区域爬坡时出现的断线问题，从而提高白色OGS触摸基板的良率和产品性能。

具体实施方式
为了减轻或避免触控电极在边缘区域爬坡时出现断线的问题，从而提高触摸基板的良率和产品性能，本发明实施例提供了触摸基板及其制作方法、触摸显示面板。在本发明的实施例的技术方案中，通过将光阻层与触控电极层做在基板的不同表面来避免触控电极在爬坡位置出现断线的问题。下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制本发明的范围。
图3是本发明实施例提供的一种触摸基板的剖面图，该触摸基板包括基板1、光阻层6和触控电极层3，所述光阻层6位于所述基板1的第一表面周边，所述触控电极层3位于所述基板1的第二表面。
在实施例中，基板1可以为不同材料的基板，例如，该基板1可以为强化玻璃，所述触控电极层可以是ITO(氧化铟锡)或其他金属材料。
本发明实施例提供的触摸基板，通过将光阻层6与触控电极层3做在基板1的不同表面，可以规避触控电极层在基板边缘区域爬坡时出现的断线问题，从而提高触摸基板的良率和产品性能。
在一个实施例中，所述光阻层6可以为白色光阻层，相较于黑色光阻，用白色光阻做成的触摸基板边框材料更加美观。
但白色光阻的光学密度值(OD值)较低，遮光性较差，所以，用白色光阻做触摸基板的边框材料时，为了达到较好的遮光效果，需要将白色光阻做得较厚，一般都在15um及以上，但这样不利于触摸基板的轻薄化。
因此，为了能够提高光阻的光学密度值，实现较好的遮光效果，同时能够将触摸基板做的更加轻薄，本发明的另外的实施例提供了另一种触摸基板。如图4所示，该触摸基板包括基板1，触控电极层3，光阻层可包括白色光阻层21和黑色光阻层7，所述白色光阻层21和所述黑色光阻层7位于所述基板1的第一表面周边，所述触控电极层3位于所述基板1的第二表面。所述黑色光阻层7可位于所述基板1与所述白色光阻层21之间，利用黑色光阻光学密度值高、遮光性好的性质，可以将黑色光阻层和白色光阻层均做得很薄，既能够实效遮光好的效果，又能够使触摸基板轻薄化，同时，将所述白色光阻层21做在所述黑色光阻层7上面还能达到美观的目的。
此外，如图3和图4所示，光阻层上方可设置有覆盖所述基板1整个第一表面的第一保护层5，所述基板1的第二表面可设置有覆盖所述触控电极层3的第二保护层4，可分别用来保护光阻层和触控电极层不被刮伤。
特别地，所述第一保护层5在光阻层上方覆盖所述基板1整个第一表面，还可以平坦化光阻层与基板之间的高度差，并且能够达到消影的目的。
在实施例中，第一保护层5和第二保护层4可以用有机绝缘材料或无机绝缘材料制作。
为了不影响显示区域的光线出射，有益于实现触控显示，所述触控电极层可以为透明导电材料制作而成。
本发明实施例还提供了一种触控面板，该触控面板包括上述实施例中的任一实施例所描述的触摸基板。
在一个实施例中，该触控面板可包括显示面板和设置于所述显示面板出光侧的触摸基板。
在上述实施例中，通过将光阻层6与触控电极层3做在基板1的不同表面，与现有技术相比，可以减轻或避免触控电极层3在基板1边缘区域爬坡时出现的断线问题，从而提高触摸基板的良率和产品性能。进一步地，边框材料采用白色光阻层21和黑色光阻层7组合的方式，在保证好的遮光效果的同时，可以实现轻薄的白色OGS产品。
此外，本发明的另外的实施例还提供了一种触摸基板的制造方法，包括：
步骤S1：提供一基板；
步骤S2：在所述基板第一表面周边形成光阻层；
步骤S3：在所述基板第二表面形成触控电极层。
具体地，在步骤S2中，可经过涂覆、曝光和显影等工序，在所述基板第一表面周边形成光阻层，与利用油墨印刷等方式相比，这种生产工艺更加容易实现，特别是对于大世代线(6代以上)来说，更加适用。
在一个实施例中，在步骤S2中，可以在所述基板第一表面周边先形成黑色光阻层，然后在所述黑色光阻层上方形成白色光阻层。这样，利用黑色光阻光学密度值高、遮光性好的性质，可以将黑色光阻层和白色光阻层均做得很薄，既能够实效遮光好的效果，又能够使触摸基板轻薄化，同时，将所述白色光阻层做在所述黑色光阻层上面还能达到美观的目的。
在一个实施例中，在步骤S3中，可以在不低于300℃温度下在所述基板第二表面形成导电膜层；对所述导电膜层进行构图工艺形成包括所述触控电极层的图形。因为白色光阻属于有机材料，所以，现有技术中，制作触控电极层必须在低温(300℃以下)下进行，而低温制作触控电极层容易使触控电极层的附着性和电阻的均匀性降低，而本实施例提供的技术方案可以使触控电极层的制作不再受制于白色光阻材料，触控电极层可以在高温(不低于300℃)条件下制作，有效的提高了触控电极层的附着性和电阻的均匀性。
具体地，可以采用溅射或者镀膜工艺形成所述导电膜层。
在其它的实施例中，在步骤S3之后，可以在所述基板第一表面形成第一保护层，所述第一保护层位于光阻层上方覆盖所述基板整个第一表面，所述第一保护层不仅能够保护光阻层不被刮伤，还能够平坦化光阻层与所述基板之间的高度差，同时，该第一保护层还能够起到消影的效果。同样的，为了保护触控电极层不被刮伤，在形成第一保护层后，可以在所述基板第二表面形成覆盖所述触控电极层的第二保护层。
需要说明的是，光阻层，触控电极层，第一保护层及第二保护层的制作顺序可以根据工艺的不同进行选择，只需使得第一保护层在光阻层制作完成之后制作，第二保护层在触控电极层制作完成之后制作。
以上实施方式仅用于说明本发明，而并非对本发明的限制，有关技术领域的普通技术人员，在不脱离本发明的精神和范围的情况下，还可以做出各种变化和变型，因此所有等同的技术方案也属于本发明的范畴，本发明的专利保护范围应由权利要求限定。
