Description

一种单层互容式触摸面板及电容式触摸屏
本申请要求享有2014年9月1日提交的名称为“一种单层互容式触摸面板及电容式触摸屏”的中国专利申请CN201410440649.5的优先权，其全部内容通过引用并入本文中。
技术领域
本发明涉及显示技术领域，尤其涉及一种单层电容触控面板及电容式触摸屏。
背景技术
触控是目前最简单、方便的一种人机交互方式，因此触摸屏越来越多地应用到各种电子产品中。基于不同的工作原理以及传输信息的媒介，触摸屏产品可以分为四种：红外线触摸屏、电容式触摸屏、电阻触摸屏和表面声波触摸屏；其中电容式触摸屏由于具有寿命长、透光率高、可以支持多点触控等优点成为目前主流的触摸屏技术。
电容式触摸屏包括表面电容式和投射电容式，其中投射电容式又可分为自电容式和互电容式。其中，互电容式是在基板(通常为玻璃基板)表面用氧化铟锡(Indium Tin Oxide，简称ITO)制作感应电极Rx与扫描电极Tx，两组电极交叉的地方将会形成耦合电容，即这两组电极分别构成了耦合电容的两极。当手指触摸到电容屏时，影响了触摸点附近两个电极之间的耦合，从而改变了这两个电极之间的耦合电容的大小。根据互容式触摸屏二维电容变化量数据，可以计算出每一个触摸点的坐标，因此，屏上即使有多个触摸点，也能计算出每个触摸点的真实坐标。
现有的互容式触摸屏主要分为两种，一种是将感应电极Rx和扫描电极Tx分别用两层ITO导电材料层制作，设置在不共面的两平行面上，称为双层ITO互容式触摸屏(Double Layer ITO，简称DITO)，这种触摸屏生产工艺复杂，生产良率受到生产工艺的制约；还有一种是将感应电极Rx和扫描电极Tx设置在同一平面上的单层ITO互容式触摸屏(Single Layer ITO，简称SITO)，生产工艺较DITO简单，因此为当前的主流产品。
发明人发现，现有的扫描电极Tx的驱动方式为逐行扫描，扫描频率较低，导致SITO 无法实现高频扫描，扫描触控信号的准确度不够高。
发明内容

其中，任一触控单元的扫描电极相连，位于同一行的触控单元的第一感应电极相连，位于同一列的触控单元的第二感应电极相连。
第一感应电极和第二感应电极为条状结构，第一感应电极和第二感应电极平行。

同一触控单元的第一子扫描电极与第二感应电极之间的距离为10至20微米，同一触控单元的第二子扫描电极与第一感应电极之间的距离为10至20微米。

在本发明实施例的技术方案中，提供了一种单层互容式触摸面板，该单层互容式触摸面板包括多个触控单元，任一触控单元包括扫描电极、第一感应电极和第二感应电极。本 发明中，位于同一行的触控单元的第一感应电极相连，位于同一列的触控单元的第二感应电极相连，利用所述第一感应电极感应触控信号的纵向坐标，所述第二感应电极感应触控信号的横向坐标，并且该单层互容式触摸面板上的任一触控单元的扫描电极相连，使得整个单层互容式触摸面板上的扫描电极可以在同一时刻进行扫描，从而使得本发明中的单层互容式触摸面板可以实现高频扫描，提高扫描触控信号的准确度。
本发明第二方面提供了一种电容式触摸屏，包括上述的单层互容式触摸面板。
本发明的其它特征和优点将在随后的说明书中阐述，并且，部分地从说明书中变得显而易见，或者通过实施本发明而了解。本发明的目的和其他优点可通过在说明书、权利要求书以及附图中所特别指出的结构来实现和获得。

具体实施方式
以下将结合附图及实施例来详细说明本发明的实施方式，借此对本发明如何应用技术手段来解决技术问题，并达成技术效果的实现过程能充分理解并据以实施。需要说明的是，只要不构成冲突，本发明中的各个实施例以及各实施例中的各个特征可以相互结合，所形成的技术方案均在本发明的保护范围之内。
本发明实施例提供一种单层互容式触摸面板，如图1所示，该单层互容式触摸面板包括基板1和位于所述基板1上的多个阵列排布的触控单元2。具体的，所述触控单元2包括扫描电极3、第一感应电极4和第二感应电极5，扫描电极3分别与第一感应电极4、第二感应电极5相靠近形成互电容。第一感应电极4感应触控信号的纵向坐标，第二感应电极5感应触控信号的横向坐标，即第一感应电极4和第二感应电极5共同作用可感应出 触控信号的具体坐标，便于该单层互容式触摸面板作出具体反馈。
其中，如图1所示，任一触控单元2的扫描电极3相连，位于同一行的触控单元2的第一感应电极4相连，位于同一列的触控单元2的第二感应电极5相连。
在本发明实施例的技术方案中，提供了一种单层互容式触摸面板，该单层互容式触摸面板包括多个触控单元，任一触控单元包括扫描电极、第一感应电极和第二感应电极。本发明中，位于同一行的触控单元的第一感应电极相连，位于同一列的触控单元的第二感应电极相连，利用所述第一感应电极感应触控信号的纵向坐标，所述第二感应电极感应触控信号的横向坐标，并且该单层互容式触摸面板上的任一触控单元的扫描电极相连，使得整个单层互容式触摸面板上的扫描电极可以在同一时刻进行扫描，从而使得本发明中的单层互容式触摸面板可以实现高频扫描，提高扫描触控信号的准确度。
在本发明实施例中，将任一触控单元2的扫描电极3相连之后，当该单层互容式触摸面板发出扫描信号时，任一触控单元2的扫描电极3可以在同一时刻进行扫描。即如图2所示，每一扫描电极3(图2中的Tx1，Tx2，…Txn)在同一时刻接收到单层互容式触摸面板发出的高电平的扫描信号，进而进行扫描。因此，可将所述扫描电极的扫描频率提升为200至300兆赫兹甚至更高，例如500兆赫兹。
优选的，为了保证触控单元2的结构紧凑，如图1所示，第一感应电极4和第二感应电极5可均为条状结构，第一感应电极4可和第二感应电极5平行。
具体的，如图1所示，扫描电极3可包括第一子扫描电极31，第一子扫描电极31也可为条状，其位于所述第一感应电极4和所述第二感应电极5之间且平行于所述第一感应电极4和第二感应电极5设置。
此时，如图1所示，第一子扫描电极31位于第一感应电极4和第二感应电极5之间，分别与第一感应电极4和第二感应电极5相靠近形成互电容。为了保证第一子扫描电极31和第一感应电极4之间、以及第一子扫描电极31和第二感应电极5之间能够形成互电容，优选的，第一子扫描电极31与第一感应电极4、所述第二感应电极5的距离为10至20微米。
在前文中提及，本发明实施例中的任一触控单元2的扫描电极3相连。因此，为了简化基板上的走线、降低制作工艺的难度，如图1所示，可将位于同一列的各触控单元2的第一子扫描电极31一体成型，且任意列的第一子扫描电极31相连，即每一列的第一子 扫描电极31在基板1边缘相连。
由于图1中，第一子扫描电极31和第一感应电极4的相对面积较小，导致第一子扫描电极31和第一感应电极4形成的互电容的电容值较小。为了提升扫描电极3和第一感应电极4之间的互电容的电容值的大小，使得扫描电极3和第一感应电极4之间的感应效果更好，进而间接提高该单层互容式触摸面板的感应触控信号的准确性。如图2所示，扫描电极3还包括第二子扫描电极32，第二子扫描电极32连接第一子扫描电极31，该第二子扫描电极32为具有开口的框型，第一感应电极4位于所述第二子扫描电极32的框型的内部区域。
具体的，在图3中，为框型的第二子扫描电极32的任一长边与第一感应电极4平行，开口开设在其中一长边的中部，另一长边位于所述第一感应电极4和所述第一子扫描电极31之间。位于同一行的触控单元2的第一感应电极4可自各自对应的第二子扫描电极32的开口延伸出走线，同一行的各第二子扫描电极32的走线在基板1的边缘、未设置有触控单元2的地方连接，向单层互容式触摸面板的分析处理单元反馈第二子扫描电极32上的电势变化情况，以便于基板1上的分析处理单元判断是否有触控信号。
需要说明的是，如图1或图3所示，各第一感应电极4的走线可在走线稀疏处适当增大宽度。这是为了减小走线的电阻，保证各第一感应电极4的工作效果，进而保证该单层互容式触摸面板的感应触控信号的准确程度；另外，还可增加基板1上的走线的排布的密集程度，保证用户的观赏效果。
另外，在本发明实施例中，如图3所示，可将所述第二子扫描电极32的长边与所述第一子扫描电极31连接，以使得第一子扫描电极31和第二子扫描电极32成为一体。
为了既保证第二子扫描电极32与第一感应电极4之间的相对面积足够大、又简化图2中的触控单元的走线，优选的，可将同一触控单元2的第一子扫描电极31与第二子扫描电极32的一边重合。例如，如图4所示，将图3中第二子扫描电极32靠近第一子扫描电极31的长边与第一子扫描电极31重合。
类似的，为了图3或图4中的保证第一子扫描电极31和第二感应电极5之间形成互电容，同一触控单元2的第一子扫描电极31与第二感应电极5之间的距离为10至20微米。相应的，同一触控单元2的第二子扫描电极32与第一感应电极4之间的距离也应为10至20微米。
进一步的，本发明实施例还提供了一种电容式触摸屏，该电容式触摸屏包括上述的单层互容式触摸面板，可用于液晶电视、液晶显示器、手机、平板电脑等显示装置。
虽然本发明所公开的实施方式如上，但所述的内容只是为了便于理解本发明而采用的实施方式，并非用以限定本发明。任何本发明所属技术领域内的技术人员，在不脱离本发明所公开的精神和范围的前提下，可以在实施的形式上及细节上作任何的修改与变化，但本发明的专利保护范围，仍须以所附的权利要求书所界定的范围为准。
