Description

检测触摸屏波纹的检测板、检测组件和检测方法
本申请要求于2014年12月30日递交的、申请号为201410842485.9、发明名称为“检测触摸屏波纹的检测板、检测组件和检测方法”的中国专利申请的优先权，其全部内容通过引用并入本申请中。
技术领域
本发明的实施例涉及触摸屏检测技术，尤其涉及一种检测触摸屏波纹的检测板、检测组件和检测方法。
背景技术
目前电容式触摸屏已经广泛用于手机、平板电脑等领域。传统的电容式触摸屏一般都是采用将一层盖板玻璃与一层触控玻璃通过光学胶(OCA)(Optical Clear Adhesive)或水胶(OCR)(Optical Clear Resin)贴合的结构，即GG(Cover Lens+Glass Sensor)结构。但是，随着对触摸屏轻、薄、低成本化的不断追求，GG结构逐渐被GF(Cover Lens/Film Sensor盖板玻璃/感应薄膜)、GFF(Cover Lens/Film Sensor/Film Sensor盖板玻璃/感应薄膜/感应薄膜)、OGS(One Glass Solution触控盖板玻璃)等结构所替代。
GF或者GFF结构是将一层盖板玻璃与一层或者两层柔性的触控感应薄膜通过光学胶(OCA)或水胶(OCR)等粘合剂贴合而成的结构。这两种结构在轻、薄、低成本化方面均具有一定的优势，目前已经成为触摸屏市场上的主流结构之一。但是，由于将玻璃盖板与触控感应薄膜通过光学胶(OCA)或水胶(OCR)贴合属于软贴硬或硬贴软的工艺，贴合时很容易造成感应薄膜不平整，形成类似水波纹的波纹(触摸屏波纹)，特别是在触摸屏的油墨区与可视区的交界处，更易于产生波纹，从而影响产品良率。
为避免不合格产品流入市场，在出厂前需对触摸屏波纹进行检测。现今主要通过操作员将每片贴合后的成品触摸屏与标准样本进行比对，判断贴合后的触摸屏是否满足出厂标准。但是这种与标准样本进行比较的判断方法具有一定的主观性，很容易造成误判，导致错误的检测结果；并且需要具备高度专业水平的检测人员来实施。因此，需要一种能够容易地、准确地检测触摸屏波纹的方法。
发明内容

附图说明
图1的透视图示出根据本发明的一个实施例的使用检测板检测触摸屏波纹的方法的原理示意图。
图2的透视图示出根据本发明的一个示例实施例的用于支撑检测板和/或触摸屏的支架的结构。
具体实施方式
在下面的详细描述中，为便于解释，阐述了许多具体的细节以提供对本发明实施例的全面理解。然而明显地，一个或多个实施例在没有这些具体细节的情况下也可以被实施。在附图中，公知的结构和装置可能被省略以简化附图。
图1示出了根据本发明的一个实施例的使用检测板检测触摸屏10上的波纹的方法的原理示意图。如图1所示，触摸屏10包括：玻璃板11；在玻璃板11上外周边 部位处形成的不透光的油墨区12(为清楚起见，图中只示出一个外周边部位处的油墨区)；覆盖在玻璃板11和油墨区12上的诸如光学胶或水胶等粘接剂层13；以及通过粘接剂层13贴附在玻璃板11上的柔性薄膜14，所述柔性薄膜14为触控感应薄膜。
为了检测触摸屏10上的波纹的情况，根据本发明的一个实施例，提供一检测板20，所述检测板20的一个表面上设置有由沿第一方向延伸的多条平行排列的网格线L1和沿第二方向延伸的多条平行排列的网格线L2交叉形成的规则排列的多个网格21。如图1所示，使检测板20的形成有网格21的所述表面与触摸屏10的玻璃板11所在的一侧的表面成预定角度α放置，使得检测板20在触摸屏10上形成检测板图像20’，并且，网格线L1和L2成像在触摸屏10上，形成成像的网格线L1’和L2’，从而在触摸屏10的表面上形成由成像的网格线L1’和L2’构成的成像的网格21’。若是触摸屏上没有波纹，成像在整个触摸屏上的网格线将呈现规则的直线排列；若触摸屏上具有波纹，成像在触摸屏上的波纹处的网格线将会由于光学现象呈现弯曲排列，在无波纹处成像的网格线则呈现直线规则排列。
在一个示例中，如图1所示，由于在触摸屏10中在油墨区12的边界处产生波纹，因此，成像在触摸屏10的表面上的网格线L1’在油墨区12的边界处发生弯曲。通过观察弯曲的网格线的位置，即可容易地确定在触摸屏10中存在波纹的位置。并且，根据弯曲的网格线部分15的宽度，即可判断触摸屏10中的波纹的大小。
更具体地，通过沿着发生弯曲的网格线L1’的方向计数发生弯曲的网格线部分15所包括的网格21’的数量，即可定量地判断触摸屏10中的波纹的大小。
根据一个具体实施例，为了容易地计算波纹的宽度，将检测板20形成为与触摸屏10的形状一致的矩形板，并且，平行于矩形板的长边和短边形成水平和垂直的网格线L1和网格线L2，并且由相互垂直的网格线L1和网格线L2组成正方形的网格21。优选地，每个正方形网格21的尺寸为10mm×10mm。当进行检测时，如图1所示，沿着触摸屏10的一个边缘放置检测板20，使检测板20的边缘平行且邻近触摸屏10的边缘或与触摸屏10的边缘重合，并且使检测板20与触摸屏10之间的预定角度α形成为60°的角度。
通过这样设置检测板20与触摸屏10的角度，当检测板20上的网格线在触摸屏10上成像时，沿着在触摸屏10上成像的网格线L1’的网格的宽度等于检测板上的相应网格宽度的一半。例如，当检测板20上的网格为10mm×10mm时，在触摸屏10上沿着L1’的网格的宽度等于5mm。因此，根据该实施例，便于定量计算网格的宽 度，从而便于计算触摸屏10中的波纹的宽度。并且，当沿着触摸屏10的边缘放置检测板20时，便于检测易于产生波纹的触摸屏10的周边部分处(特别是，油墨区与显示区的交界部分处)的波纹。可选地，可以分别沿着触摸屏10的四个边缘放置检测板20，以检测四个边缘处的波纹，最后可以取水波纹最严重的区域的检测结果作为波纹的检测结果。
本领域技术人员应当理解，上述实施例只是检测波纹的一个示例。实践中，可以任意设置检测板20与触摸屏10之间的角度α，只要能够将网格线清楚地成像在触摸屏10上即可；并且，网格线的方向、网格的尺寸也可以任意设置，只要能够形成均匀的网格即可。另外，检测板20可以沿任意方向邻近触摸屏10放置，而不一定沿着触摸屏10的边缘放置，以用于检测任意方向的波纹。
另外，上述实施例以GF结构的触摸屏为例说明了本发明的检测波纹的方法。但是，本发明的检测波纹的方法不限于GF结构的触摸屏，例如可以用于GFF结构的触摸屏，以及需要检测波纹的其它结构的触摸屏。
根据一个实施例，为了便于设置检测板20与触摸屏10的角度，可以提供一种用于支撑检测板20和/或触摸屏10的支架，使得检测板20与触摸屏10以预定的角度放置，并且使检测板20的一个边缘邻近触摸屏10的一个边缘。
图2示出了一个示例性的用于支撑检测板20和/或触摸屏10的支架30的构造。如图2所示，所述支架30包括用于保持检测板20的第一支架31和用于保持触摸屏10的第二支架32，所述第一支架31和所述第二支架32形成预定的角度，例如45°、60°等适当的角度。
具体地，第一支架31包括用于放置检测板20的从第一支架31的表面下凹的基座33，所述基座33形成开口区域35以露出检测板20上的网格线。第二支架32包括用于放置触摸屏10的从第二支架32的表面下凹的基座34，所述基座34形成开口区域36。可选地，可以不形成开口区域36。
利用所述支架30，可以方便地放置检测板20和触摸屏10，并便于固定检测板20和触摸屏10的角度。
当然，本领域技术人员可以设计其它构造的支架，所述支架可以仅支撑检测板20，或者仅支撑触摸屏10，或者分别制造支撑检测板20和触摸屏10的两个分开的支架、然后再组装在一起。
以下说明制造本发明的检测板的示例方法。
根据一个示例性实施例，制造检测板20的步骤包括：提供一矩形底板，底板的材 质没有限制，可以为塑料板、金属板或玻璃板等；制作一具有黑色背景和在黑色背景上的由沿第一方向延伸的多条白色网格线和沿第二方向延伸的多条白色网格线交叉形成的规则排列的多个网格的纸片；以及将纸片贴附在底板上，形成检测板20。
根据另一个示例性的实施例，制造检测板20的步骤包括：提供一矩形底板，所述矩形底板具有一个黑色表面和在矩形底板的黑色表面上形成的由沿第一方向延伸的多条白色网格线和沿第二方向延伸的多条白色网格线交叉形成的规则排列的多个网格，其中白色网格线例如通过刻划或涂敷等方式形成。
本领域技术人员可以理解，在上述制造检测板20的实施例中，底板不一定是矩形，可以为其它形状。纸片不一定为黑色背景，底板也不一定包括黑色表面，网格线也不一定是白色。相反，只要网格线和其背景的颜色形成鲜明的对比以便于观察，网格线和其背景可以采用其它颜色。
以上通过实施例描述了本发明的检测触摸屏波纹的方法及其所用的检测板和支架。根据所述方法，能够定性和定量地测量触摸屏上水波纹的宽度，判断水波纹的等级，避免误判的发生，防止不合格产品投放市场引起客户抱怨和损失产品形象。
应当理解，上述实施例仅例示性的说明了本发明的原理及构造，而非用于限制本发明，本领域的技术人员应明白，在不偏离本发明的总体构思的情况下，对本发明所作的任何改变和改进都在本发明的范围内。本发明的保护范围，应如本申请的权利要求书所界定的范围为准。应注意，措词“包括”不排除其它元件或步骤，措词“一”或“一个”不排除多个。
