Description

一种触控面板以及显示装置 技术领域
本发明涉及显示技术领域，特别涉及一种触控面板以及显示装置。
 背景技术
随着科技的发展，可触摸显示屏正在变得日益普及。可触摸显示屏包括触摸面板以及重叠设置的显示面板。这样显示面板可以完成各种显示功能，触摸面板则可对可触摸显示屏上的触摸动作进行识别。触摸面板包括触控线以及感应线，这样触摸面板可叠加在显示面板上，形成可触摸显示屏。
如图1所示，传统的单层（Single Layer）触控面板（Touch Panel）中的所有的触控线101均设置于感应线102的两侧，以实现单层多点触控功能。
在实践中，发明人发现现有技术至少存在以下问题：
如图1所示，由于传统的单层触控面板中的ITO（氧化铟锡）的阻抗较大，因此触控线101无法做得很细，也就是说，触控线101具有较宽的宽度，这会导致触控线101占据了该单层触控面板中的较大面积，而且，由于所有的触控线101均设置于感应线102的两侧，如图1所示，因此，触控感测有效区的面积会相对地减小，触控感测盲区（虚线框部分）的面积则会相对地增加。
故，有必要提出一种新的技术方案，以解决上述技术问题。

实施例三
请参阅图4，图4为本发明实施例三提供的触控面板的结构示意图。为了便于说明，仅示出了与本发明实施例相关的部分。本实施例三与上述实施例一相似，不同之处在于：
所述触控面板还包括：方向触控线204，设置在所述感应延长线203与所述感应延长线203相邻的所述触控线202之间，以在所述触控区域与所述感应延长线203形成互电容。
在本发明实施例中，所述方向触控线204的形状与所述感应延长线203的形状相同。例如，所述方向触控线204的形状呈L型。即该L型线设置在所述感应延长线203与所述感应延长线203相邻的所述触控线202之间，以在所述触控区域与所述感应延长线203形成互电容，有效减少了盲区的面积。
在本发明实施例中，由所述感应线201和所述触控线202形成互电容，当按压在所述感应线201和所述触控线202上时，由于所述感应线201和所述触控线202不同位置产生的电容值不同，因此可根据电容值来确定触控点的位置。
由上可知，本实施例三在所述感应延长线203与所述感应延长线203相邻的所述触控线202之间设置方向触控线204，该方向触控线204呈L型，该方向触控线204的末端与所述感应延长线形成互电容，因此减少了屏幕下端边缘区域的盲区面积。
实施例四
本发明实施例四提供了一种显示装置。为了便于说明，仅示出了与本发明实施例相关的部分。所述显示装置包括显示面板，以及叠加在所述显示面板上的触控面板。这样显示面板可以完成各种显示功能，触摸面板则可对可触摸显示屏上的触摸动作进行识别。
所述触控面板包括：多条感应线201，设置在感应区域，用于产生感应信号；多条触控线202，设置在触控区域，用于接收触控信号；其中多条所述触控线202伸入所述感应区域，以形成互电容；其中所述感应线201向所述触控区域延伸一感应延长线203，以在所述触控区域形成互电容；方向触控线204，设置在所述感应延长线203与所述感应延长线203相邻的所述触控线202之间，以在所述触控区域与所述感应延长线203形成互电容；从而有效减少了盲区的面积，因此更能够精确的定位触控点位置。
在本发明实施例中，所述感应延长线203与所述感应线201末端连接。
在本发明实施例中，所述方向触控线204为竖向排列的一条直线，即该直线设置在所述感应延长线203与所述感应延长线203相邻的所述触控线202之间，以在所述触控区域与所述感应延长线203形成互电容。
然而，可以理解的是，所述方向触控线204的形状与所述感应延长线203的形状相同。例如，所述方向触控线204的形状呈L型。即该L型线设置在所述感应延长线203与所述感应延长线203相邻的所述触控线202之间，以在所述触控区域与所述感应延长线203形成互电容。
在本发明实施例中，由所述感应线201和所述触控线202形成互电容，当按压在所述感应线201和所述触控线202上时，由于所述感应线201和所述触控线202不同位置产生的电容值不同，因此可根据电容值来确定触控点的位置。
由上可知，本实施例四在触控面板的感应区域的两侧均设置有感应延长线，左侧的所述感应延长线与所述触控线TX5形成互电容，右侧的所述感应延长线与所述触控线TX4形成互电容，因此减少了所述触控线TX5区域以及所述触控线TX4区域的盲区面积。以及，在所述感应延长线203与所述感应延长线203相邻的所述触控线202之间设置方向触控线204，该方向触控线204呈L型，该方向触控线204的末端与所述感应延长线形成互电容，因此减少了屏幕下端边缘区域的盲区面积。
综上所述，本发明提供的触控面板及显示装置，通过在触控区域（即盲区）增设感应延长线，以在所述触控区域形成互电容，从而使得所述盲区具有互电容，有效减少了盲区的面积，使得所述触控面板所对应的线性度的波动较小，因此能够更加精确的定位触控点位置。
尽管已经相对于一个或多个实现方式示出并描述了本发明，但是本领域技术人员基于对本说明书和附图的阅读和理解将会想到等价变型和修改。本发明包括所有这样的修改和变型，并且仅由所附权利要求的范围限制。特别地关于由上述组件执行的各种功能，用于描述这样的组件的术语旨在对应于执行所述组件的指定功能（例如其在功能上是等价的）的任意组件（除非另外指示），即使在结构上与执行本文所示的本说明书的示范性实现方式中的功能的公开结构不等同。此外，尽管本说明书的特定特征已经相对于若干实现方式中的仅一个被公开，但是这种特征可以与如可以对给定或特定应用而言是期望和有利的其他实现方式的一个或多个其他特征组合。而且，就术语“包括”、“具有”、“含有”或其变形被用在具体实施方式或权利要求中而言，这样的术语旨在以与术语“包含”相似的方式包括。
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。
