Description

增大互容的触控屏金属网格结构 技术领域
本发明涉及触控屏技术领域，特别是涉及一种显示面板上的增大互容触控屏金属网格装置。

与传统的TFT-LCD（thin film transistor-liquid crystal display，薄膜晶体管液晶显示器）技术相比，OLED（Organic Light-Emitting Diode，有机电致发光器件）具有可做成柔性器件的优势，OLED显示面板具有对比度高、厚度薄、视角广、反应速度快、使用温度范围广、构造及制程较简单等特性，受到业界的广泛关注，尤其是柔性OLED显示面板，在便携式显示设备、可穿戴电子产品和商场显示屏幕等领域有着广阔的应用前景。然而随着移动终端屏幕的增大，移动终端的尺寸也越来越大，便携性也相应降低。为了解决上述问题，柔性显示装置应运而生，由于柔性显示装置具有在一定形变范围内，仍可工作的特性，因此可以使大尺寸显示装置可以通过折叠的方式，实现便携性。
但在显示面板上制作内嵌式触控层时，由于受到阴极及其他电场的影响，导致触控层互感电容信号受到的杂讯干扰很大，特别是柔性OLED，封装层更薄，杂讯影响更大，所以如何增大触控层的互感电容，提升触控灵敏度，是目前面板内嵌式触控所面临的问题。现有的做法是在驱动集成电路中引入一个升压(Pump)装置，用以提升触控信号强度，但这样的做法带来的一个不利因素就是能耗会变大，对于以节能为优势的显示装置是一个严重缺点。故需要提供一种新的增大互容触控屏金属网格装置，以改善上述问题。

在图中，结构相似的单元是以相同标号表示。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本发明的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
本发明实施例提供了一种增大互容的触控屏金属网格结构，其包括：一基板10、一驱动层20、一感应层30与一电容检测装置(图中未示)。本发明提供一种触控屏金属网格设计方案，通过增大驱动线路Tx和感测线路Rx的接触面积，以增大互感电容，从而提升触控信号的强度，降低杂讯对触控信号的影响。其中，所述驱动层20设置在所述基板上，所述驱动层20包括复数个圆形图案22，各圆形图案22之间通过桥线21互相连接；所述感应层30设置在所述基板10上，所述感应层30包括复数个极化四边形图案31，所述极化四边形图案31对应于所述圆形图案22设置，藉以组合形成一触控图案，所述电容检测装置(图中未示)与所述感应层30和所述驱动层20电连接。
其中，如图1所示，在基板10上制作触控层，触控图案以圆形图案22以及与其相应的极化四边形图案31，图中的圆形和极化四边形的边界线主要是为了方便图形可视化而增加的线条，实际线路不存在此线条。图1是本案效果示意图，圆形图案22的驱动线路Tx通过桥线21互相连接，极化四边形图案31横跨整个屏幕，形成Rx电极，两条Rx之间的绝缘通过断线23互相绝缘。
在一些实施例中，其中，所述圆形图案22与所述极化四边形图案31之间透过一圆形断线区23互相绝缘。
在一些实施例中，其中，所述的增大互容的触控屏金属网格结构，其中，所述圆形断线区23设置在该圆形图案22外围，断开尺寸为1µm-20µm。
在一些实施例中，其中，所述的增大互容的触控屏金属网格结构，其中，所述驱动层20与所述感应层30上更覆盖一绝缘层40。
在一些实施例中，其中，所述的增大互容的触控屏金属网格结构，其中，所述基板10为一OLED显示面板、一液晶面板(LCD)、一玻璃基板或一薄膜基板。
在一些实施例中，其中，所述的增大互容的触控屏金属网格结构，其中，所述薄膜基板为PI、PET或COP材料所构成。
其中，图2是一个触控单元示意图，圆形图案22和极化四边形图案31通过圆形断线区23互相绝缘，圆形断线区23在圆形图案22外围，这样金属网格在此区域断开，断开尺寸从1μm~20μm不等，视实际设计情况而定。图3和图4是桥点位置AA、BB剖面图，如图所示，在桥点区桥线以网格形式存在，网格位置与图案层网格相互重合，多重网格的优势在于桥线互联，降低桥线21断线现象发生几率。桥线21在圆形图案22中的部分与另一圆形图案22实现完全连接。在极化四边形图案31，包括断线24均处于绝缘状态。
Tx图案如图5所示，通过桥线21互相连接。Rx图案如图6所示，横向贯通，通过断线24彼此绝缘，通过断线24与Tx图案绝缘。
本发明的制作方式是在基板10上制作圆形图案22和极化四边形图案31，然后覆盖一层绝缘层40，并在桥线21处镂空，之后制作桥线层，桥线21在镂空处于圆形图案22连接。最后再覆盖一层绝缘层40。叠层结构可以参考图3、图4桥点处的剖面图。桥线层和圆形图案22、极化四边形图案31层可互相交换而不影响本案的实际效果。
本发明的另一实施例中提供了一种一种增大互容的触控屏金属网格结构，其包括：一基板10、一驱动层20、一感应层30、一绝缘层40与一电容检测装置(图中未示)。其中，所述驱动层20设置在所述基板10上，所述驱动20层包括复数个驱动部件，各驱动部件之间是通过桥线21互相连接；所述感应层30设置在所述基板10上，所述感应层30包括复数个感测部件，所述感测部件对应所述感测部件设置；所述电容检测装置(图中未示)与所述感应层30和所述驱动层20电连接，所述绝缘层40覆盖在所述驱动层20与所述感应层30上。
在一些实施例中，其中，所述的增大互容的触控屏金属网格结构，其中，所述驱动部件为圆形图案22，所述感测部件为极化四边形图案31，所述极化四边形图案31对应于所述圆形图案22设置，藉以组合形成一触控图案，所述圆形图案22与所述极化四边形图案31之间透过一圆形断线区23互相绝缘。
在一些实施例中，其中，所述的增大互容的触控屏金属网格结构，其中，所述圆形断线区23设置在该圆形图案22外围，断开尺寸为1µm-20µm。
在一些实施例中，其中，所述的增大互容的触控屏金属网格结构，其中，所述基板为一OLED显示面板、一液晶面板(LCD)、一玻璃基板或一薄膜基板。
在一些实施例中，其中，所述的增大互容的触控屏金属网格结构，其中，所述薄膜基板为PI、PET或COP材料所构成。
如图7所示，将圆形图案22和极化四边形图案31功能互换，桥线21连接极化四边形图案31，形成Tx电极，圆形图案22横贯屏幕，形成Rx图案，其它制作方式不变，桥线21处的剖面图可参考图3、图4。图8是极化四边形图案31通过桥线21连接后的Tx图案，图9是圆形图案22横贯屏幕所形成的Rx图案。
在以上2个案例中，Tx和Rx仅为了表述而进行的定义,在实际制作中不受此定义影响，Tx和Rx适当的时候可以互换。此外，本案所有图形均为示意图，不代表尺寸比例。
另外，本发明是基于圆形图案方式与利用桥接方式，本发明是以金属网格为基础进行的技术创作，因此本发明有具体的制作方式和结构。
本发明提供一种触控屏金属网格设计方案，通过增大驱动线路Tx和感测线路Rx的接触面积，以增大互感电容，从而提升触控信号的强度，降低杂讯对触控信号的影响。
本发明采用圆形图案22，使得Tx和Rx 的直接接触面积增大，这样Tx与Rx之间的互容增大，触控信号增强。而且本发明可较为有效地排除阴极及其他电场干扰信号的影响。本发明中桥线通过互联，极大降低断线风险，同时降低了桥线的线电阻，有利于触控互容的增大。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
