Description

触控显示器 技术领域
本发明属于触控显示技术领域，具体地讲，涉及一种触控显示器。
背景技术
随着显示技术的快速发展，人们对显示器的要求越来越高，高分辨率、高炫彩性、响应速度更快等性能要求也促使显示技术向更高、更强、更快、更轻薄的方向发展。有机发光二极管(Organic Light Emitting Diode，OLED)作为显示解决方案的半导体元件技术也得到了飞速的发展。就现有显示技术来说，OLED显示具有自发光、响应速度快、宽视角、适应柔性基底，既可以应用在手机、电视、电脑等常规电器上，也可以用在VR、手表、可穿戴装置等异形，甚至可折叠、可卷曲等显示领域，广泛的应用领域，使其成为未来的主流显示技术之一。因此对OLED的技术研究和发展也成为各大面板制造公司竞争未来显示市场的核心。
当前随着显示技术的发展，具有触控功能显示器，尤其是中小尺寸显示器，也越来越受市场的欢迎，由于最初触控与显示是两个相互分离的技术(即Out Cell Touch技术，有FF(Film to Film)、GF(Glass to Film)、GG(Glass to Glass)、OGS(One Glass Solution)等几种技术为代表)，具有触控功能的显示器需要将触控面板和显示面板贴合起来，但是这样就造成工艺繁杂，显示器过厚，不利于产品的轻薄化技术。于是，后来渐渐有了Oncell、Incell触控技术，这两种触控技术的使用极大地降低了工艺的繁杂程度，同时对显示器轻薄化也做出了重大贡献，并且这种与显示技术结合在一起的触控技术也无需单独建设触控工厂，因此，这一技术一经出现便得到了极大发展。
但是，随着OLED技术的出现和发展，并且越来越成为显示主流技术，尤其是柔性技术的出现，触控技术又遇上了一个瓶颈。一般情况下，Oncell技术还可以解决触控在OLED上的应用，但是其低温制程、少水工艺极大限制了触控工艺适用范畴，产品的良率和性能也会受到影响。Incell技术由于Incell制程 与OLED工艺层存在一定的冲突，很少有现实意义的发展。因此，如何将Incell技术植入OLED显示器中是一个亟需解决的技术问题。

具体实施方式
以下，将参照附图来详细描述本发明的实施例。然而，可以以许多不同的形式来实施本发明，并且本发明不应该被解释为限制于这里阐述的具体实施例。相反，提供这些实施例是为了解释本发明的原理及其实际应用，从而使本领域的其他技术人员能够理解本发明的各种实施例和适合于特定预期应用的 各种修改。
在附图中，相同的标号将始终被用于表示相同的元件。将理解的是，尽管在这里可使用术语“第一”、“第二”等来描述各种元件，但是这些元件不应受这些术语的限制。这些术语仅用于将一个元件与另一个元件区分开来。
图1是根据本发明的实施例的触控显示器的截面示意图。
参照图1，根据本发明的实施例的触控显示器包括：基板100；阳极200，设置在基板100上；触控电极结构300，设置于基板100上，触控电极结构300与阳极200绝缘；平坦层400，设置在阳极200、触控电极结构300和基板100上，平坦层400中具有设置于阳极200上的过孔410，过孔410暴露阳极200；OLED器件500，设置在阳极200上；阴极600，设置于OLED器件500上；封装层700，设置于阴极600和平坦层400上。

如此，将触控电极结构300和阳极200同层形成，在将触控电极植入到OLED显示器中实现Incell触控技术的同时，还能减少工艺复杂性，同时降低触控显示器的厚度。此外，由于触控电极结构300位于OLED器件500的下方，因此在制作时无需考虑触控显示的线度，进一步降低工艺复杂性。
图2是根据本发明的实施例的触控电极结构和阳极的平面图。
参照图2，阳极200的数量为多个，多个阳极200阵列排布，但本发明并不限制于此。
触控电极结构300的数量为两个，这两个触控电极结构300沿行方向平行排布，并且每个触控电极结构300沿列方向延伸。需要说明的是，触控电极结构300的数量并不以两个为限，其可以是一个、三个或者更多个。
每个触控电极结构300包括：沿列方向延伸的第一导电主干条310；沿列方向延伸且与第一导电主干条310平行的第二导电主干条320；沿行方向延伸 且连接到第一导电主干条310上的第一导电支干条330；沿行方向延伸且连接到第二导电主干条320上的两个第二导电支干条340；其中，两个第二导电支干条340之间插置所述第一导电支干条330。

此外，在本实施例中，感测垫300A呈矩形，但本发明并不限制于此，例如感测垫300A还可以呈菱形、三角形、正五边形、正六边形、正八变形或者其他合适的形状。
作为本发明的另一实施方式，如图3所示，感测垫300AA还可以呈网格 状。在感测垫300AA呈网格状时，感测垫300AA可以有金属制成，金属制成的网格状的感测垫300AA具有敏感度高、反应灵敏等特征，还可以降低制作成本，并且工艺难度也会降低。
图4是根据本发明的实施例的触控电极结构的等效结构示意图。
参照图4，将图2所示的触控电极结构300等效为图4中所示的触控电极结构AP。在图4中，列举了n个触控电极结构AP1、AP2、……、APn。这n个触控电极结构AP1、AP2、……、APn沿行方向平行排布。此外，图4中还示出了n条信号线Tx1、Tx2、……、Txn，m条信号线Rx1、Rx2、……、Rxm。
此外，触控电极结构APi(1≤i≤n)中包括沿列方向排布的m个第二导电主干条320，这样，n个触控电极结构AP1、AP2、……、APn的n*m个第二导电主干条320阵列排布。
触控电极结构APi的第一导电主干条310独立地传输信号，并且触控电极结构APi的第一导电主干条310连接到对应的信号线Txi。根据本发明的实施例的触控显示器还包括多个n个切换器SW1、SW2、……、SWn。切换器SWi对应触控电极结构APi，并且触控电极结构APi中的m个第二导电主干条320通过与触控电极结构APi对应的切换器SWi分别连接到m条信号线Rx1、Rx2、……、Rxm。然而，位于同一行的第二导电主干条320通过各自对应的切换器连接到同一信号线上，例如，位于第一行的第二导电主干条320通过各自对应的切换器SW1、SW2、……、SWn连接到信号线Rxm上，但本发明并不限制于此。
图5是图4所示的触控电极结构的等效结构的驱动波形图。
参照图4和图5，在预定时间驱动信号线Txi，并且将切换器SWi打开，从而通过m条信号线Rx1、Rx2、……、Rxm分别接收触控电极结构APi的m个第二导电主干条320的感应信号，以此完成触控操作。这样，在第一预定时间T1内驱动信号线Tx1，打开切换器SW1，从而通过m条信号线Rx1、Rx2、……、Rxm分别接收触控电极结构AP1的m个第二导电主干条320的感应信号。在第二预定时间T2内驱动信号线Tx2，打开切换器SW2，从而通过m条信号线Rx1、Rx2、……、Rxm分别接收触控电极结构AP2的m个第 二导电主干条320的感应信号；以此类推，从而完成n个触控电极结构AP1、AP2、……、APn的触控感应驱动和侦测。这样，在预定时间内只开启第i个切换器SWi，可以避免其他感应线路造成的噪声。
综上所述，根据本发明的实施例，在将触控电极结构植入到OLED显示器中的同时，还能减少工艺复杂性，同时降低触控显示器的厚度。
虽然已经参照特定实施例示出并描述了本发明，但是本领域的技术人员将理解：在不脱离由权利要求及其等同物限定的本发明的精神和范围的情况下，可在此进行形式和细节上的各种变化。
