图3是图1所示的电感触控式显示装置沿虚线CD的剖视图；
图4是电感触控式显示装置的制造方法的流程图。
【具体实施方式】
请参考图1-图3，图1是本发明实施例的电感触控式显示装置的平面结构示意图，图2和图3分别是图1所示的电感触控式显示装置沿虚线AB和虚线CD的剖视图。如图1-图3所示，本实施例的电感触控式显示装置10包括基板11和设置在基板11上的电感触控模块12。其中，电感触控模块12包括依次彼此绝缘设置于基板11同一侧的X金属线层13、Y金属线层14以及电磁感应线圈层15。
其中，X金属线层13包括多条沿第一方向平行设置的X金属线131，Y金属线层14包括多条沿第二方向平行设置的Y金属线141。电磁感应线圈层15包括多个呈矩阵分布的电磁感应线圈151，每一电磁感应线圈151为螺旋状结构。每一电磁感应线圈151连接至一X金属线131和一Y金属线141，电磁感应线圈151与X金属线131及Y金属线141一一对应。
本实施例中，第一方向优选和第二方向垂直设置。并且如图1所示的平面图，X金属线131和Y金属线141优选均经过螺旋状结构的电磁感应线圈151的中心位置。
本实施例中的电磁感应线圈151除了如图1所示的为矩形状的螺旋状结构外，还可以为其他形状，比如圆形的螺旋状结构。
其中，基板11为彩膜基板，其包括玻璃基底111和设置在玻璃基底111上的黑色矩阵16，X金属线131、Y金属线141均设置于黑色矩阵16上方且边缘不超出黑色矩阵16，电磁感应线圈151由透明导电材料（如ITO，Indium Tin Oxide，掺锡氧化铟）制成。
其中，电感触控式显示装置10还包括设置于X金属线层13和Y金属线层14之间的第一绝缘层17和设置于Y金属线层14和电磁感应线圈层14之间的第二绝缘层18。第一绝缘层17使X金属线层13和Y金属线层14彼此绝缘，第二绝缘层18使Y金属线层14和电磁感应线圈层15彼此绝缘，第一绝缘层17和第二绝缘层18均设置于黑色矩阵16上方且边缘不超出黑色矩阵16。并且第一绝缘层17和第二绝缘层18可以为同一种有机绝缘材料构成，如橡胶、树脂、虫胶、棉纱纸、麻、蚕丝、人造丝管等。第一绝缘层17和第二绝缘层18也可以为不同的绝缘材料构成。

承前所述，本实施例通过优化电磁感应线圈151的结构，采用平面螺旋结构的设计，增大了平面线圈的扎数，进而增大触控式的感生信号电流。并且提高了电感触控式显示装置的触控灵敏度。

步骤S1：提供一基板。
该基板为彩膜基板，其包括玻璃基底和设置在玻璃基底上的黑色矩阵。因此，本步骤具体为，提供一玻璃基底，在该玻璃基底上通过涂布、曝光、显影操作，以形成黑色矩阵。
步骤S2：在基板上沉淀第一金属薄膜，进一步对第一金属薄膜进行曝光、显影、蚀刻、剥离操作，以形成具有多条沿第一方向平行设置的X金属线的X金属线层。其中，X金属线的边缘不超出黑色矩阵。
步骤S3：在X金属线层上方沉淀第二金属薄膜，进一步对第二金属薄膜进行曝光、显影、蚀刻、剥离操作，以形成具有多条沿第二方向平行设置的Y金属线的且与X金属线层绝缘的Y金属线层。其中，Y金属线的边缘均不超出黑色矩阵。其中，本实施例的第一方向优选与第二方向垂直。
在本步骤之前还包括：
在X金属线层上形成第一绝缘层，第一绝缘层设置于黑色矩阵的上方且边缘不超出黑色矩阵。
步骤S4：在Y金属线层上方沉淀透明导电薄膜，进一步对透明导电薄膜进行曝光、显影、蚀刻、剥离操作，以形成具有螺旋状结构的电磁感应线圈的电磁感应线圈层。
在本步骤之前还包括：
在Y金属线层上形成第二绝缘层，第二绝缘层设置于黑色矩阵的上方且边缘不超出黑色矩阵。
步骤S5：将每一电磁感应线圈连接至一X金属线和一Y金属线，使电磁感应线圈和X金属线及Y金属线一一对应。
具体为：螺旋状结构的电磁感应线圈的始端和终端的其中一者穿过第一绝缘层和第二绝缘层的导通孔与X金属线电连接，螺旋状结构的电磁感应线圈的始端和终端的另一者穿过第二绝缘层的导通孔与所述Y金属线电连接。
综上所述，本发明通过设置螺旋状的电磁感应线圈，增大了单位面积内平面线圈的扎数，进而增大触控式的感生信号电流。并且提高了电感触控式显示装置的触控灵敏度。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
