Description

触控面板以及触摸式显示装置
【技术领域】
本发明涉及触控领域，特别是涉及一种触控面板以及触摸式显示装置。
【背景技术】
触摸屏又称触控面板，是个可接收触头如手指触摸等输入讯号的感应式液晶显示装置，当接触了屏幕上的图形按钮时，屏幕上的触觉反馈系统可根据预先设定的驱动扫描方式，确定触摸的动作的位置，进一步确定点击的图形的按钮，确定指令类型。相较于现有技术机械式的按钮面板，触摸屏更加方便，因此得到了广泛的应用。
常用的触摸屏有很多，如矢量压力传感技术触摸屏、红外线技术触摸屏、表面声波技术触摸屏、电阻技术触摸屏等等，但是现有技术中比较常用的为电容技术的触摸屏。电容触控技术是利用手指近接电容触控面板时所产生电容变化的触控技术。包括自容式触摸技术和互容式触摸技术。以In-cell自容式触摸技术为为例，在玻璃表面用透明的导电材料制成多个触控电极，这些触控电极分别通过导线与控制器连接。触控电极分别与地构成电容，这个就是通常所说的自电容，当手指触摸到触摸屏时，手指的电容将会增加到屏体电容上，使屏体电容量增加，根据触摸前后电容的变化，可以确定触控的位置。
然而，现有技术中，触控电极与控制器之间一般都是通过单线连接在一起，如图1所示，触控电极101与控制器102之间均通过一根导线103连接在一起，但是，触摸屏在生成制造过程中，一般都需要经过曝光工艺，而在曝光工艺中，会产生灰尘、异物等微小粒子或者产生大量的静电导致导线断路，造成触控电极因信号线断路而失效。并且目前还没有一种有效的检查触控电极失效的方法，这无疑也给用户的使用带来了隐患。
【发明内容】
本发明主要解决的技术问题是提供一种触控面板以及触摸式显示装置，能够有效改善触控电极与控制器之间导线断路问题，减小次品率，也提高了触控面板的寿命。
为解决上述技术问题，本发明采用的一个技术方案是：提供一种触控面板，所述触控面板包括控制器以及多个矩阵排列的触控电极，每个所述触控电极通过至少两条导线与所述控制器的同一个引脚电连接，所述触控电极为纳米铟锡金属氧化物ITO电极，且所述触控面板为自容式触控面板。
其中，每个所述触控电极与所述控制器电连接的至少两条导线为同层走线。
其中，每个所述触控电极与控制器电连接的至少两条导线为不同层走线。
为解决上述技术问题，本发明采用的一个技术方案是：提供一种触控面板，所述触控面板包括控制器以及多个矩阵排列的触控电极，每个所述触控电极通过至少两条导线与所述控制器的同一个引脚电连接。
其中，所述触控电极为纳米铟锡金属氧化物ITO电极。
其中，每个所述触控电极与所述控制器电连接的至少两条导线为同层走线。
其中，每个所述触控电极与控制器电连接的至少两条导线为不同层走线。
其中，所述触控面板为自容式触控面板。
为解决上述技术问题，本发明采用的另一个技术方案是：提供一种触摸式显示装置，所述触摸触摸式显示装置包括：触控面板，
所述触控面板包括控制器以及多个矩阵排列的触控电极，每个所述触控电极通过至少两条导线与所述控制器的同一个引脚电连接。

其中，每个所述触控电极与控制器电连接的至少两条导线为不同层走线。
其中，所述触控面板为自容式触控面板。
本发明的有益效果是：区别于现有技术的情况，本发明的触控的上的每个触控电极分别通过至少两条导线与控制器的同一个引脚电连接，即使单根导线发生断路或其他异常现象，仍然能通过其他至少一条导线实现触控电极与控制器之间的电连接，有效减少断线等由于导线引起的异常现象，减少产品的次品率，还能节省控制器的引脚资源。并且通过至少两条导线电连接也有效延长产品的使用寿命，进一步为用户节约开销。
【附图说明】
图1是现有技术中触控电极与控制器的连接示意图；
图2是本发明触控面板一实施方式的结构示意图；
图3是图2中触控面板一具体实施方式的结构示意图；
图4是本发明触控面板另一实施方式的结构示意图；
图5是本发明触摸式显示装置一实施方式的结构示意图。
【具体实施方式】
参阅图2，图2是本发明触控面板一实施方式的结构示意图。本实施方式的触控面板为In-cell自容式触控面板。本实施方式中的触控面板包括多个矩阵排列的触控电极201以及控制器202。在本实施方式中，触控电极201为纳米铟锡金属氧化物ITO电极。
其中，每个触控电极201与控制器202之间通过至少两根导线相连接。如图2所示，在本实施方式中，每个触控电极201与控制器202之间均通过两根导线203以及204相连接。
为了使整个触控面板更加简洁，电路更加清晰，在一个优选的实施方式中，导线203以及导线204分别在所述触控电极201所处的电路板的不同的层，如触控电极201所处的电路板为4层板，导线203可置于第1层，导线204置于第4层等。
但是由于一般情况下，触控电极的分辨率比显示像素的分辨率，因此，触控面板的布线空间相对而言比较充足，因此，在另一个实施方式中，导线203以及导线204也可以同时处于所述触控电极201所处的电路板相同的层。
进一步地如图2所示，为了节省控制器202的引脚，减轻控制器202的引脚负担，优选地，每个触控电极201与控制器202相连接的两根导线203以及204在控制器202的引脚处汇聚到一根导线上，与控制器202的同一个引脚电连接。
当所述触控面板工作时，触控电极201分别与地形成电容，控制器202通过外加电源（图中未示出）实时的对触控电极201进行扫描，即不停地通过导线203以及204中的任一根对触控电极201进行充电和放电，当用户触摸到触控面板时，由于人属于导体，与触控面板本身也存在电容，影响了触控电极201与地形成的自电容的电容值，通过确定电容值发生变化的触控电极201的位置来确定用户触碰的位置。即使有单根导线出现故障，另外一根导线继续为触控电极与控制器传输信号。如图3所示。当第2列第2行的触控电极301的左侧导线303出现故障，如短路或接触不良时，右侧的导线304继续为触控电极与控制器传输信息，完全不影响触控面板的正常工作，又能节省控制器的引脚资源。
在另一个实施方式中，如图4所示，每个触控电极401与控制器402之间通过分别通过三根导线403、404以及405相连接。且进一步地如图4所示，为了节省控制器402的引脚，减轻控制器402的引脚负担，优选地，每个触控电极401与控制器402相连接的三根导线303、304以及305在控制器402的引脚处汇聚到一根导线上，与控制器402的同一个引脚电连接。即时有单根导线出现故障，另外两根中任一一根根导线继续为触控电极与控制器传输信号，完全不影响触控面板的工作，而且节省控制器的引脚资源。
在其他实施方式中也可为4条，5条，甚至更多，且同一个触控电极的多根导线在控制器的引脚处均汇聚在一根导线上，与控制器的同一个引脚电连接，在此不做限定。由于增加导线的成本远远低于对触控面板的更换，因此，通过上述方式在不增加任何成本和工艺制程的情况下减少了触控电极与控制器之间由于导线出现故障而导致的对触控面板的工作的影响，有效提高了触控面板的工作效率。
需要说明的是，本实施方式中的触控面板为In-cell自容式触控面板，但是并不完全局限于In-cell自容式触控面板，其他类型的触控面板中的触控电极与控制器之间通过超过一条的导线与控制器相连接的方案均属于本发明保护的范围，在此不一一列举。
区别与现有技术，区别与现有技术，本实施方式中的触控面板包括控制器以及多个矩阵排列的触控电极，每个触控电极通过至少两条跳线与所述控制器的同一个引脚电连接。即使单根导线发生断路或其他异常现象，仍然能通过其他至少一条导线实现触控电极与控制器之间的电连接，有效减少断线等由于导线引起的异常现象，减少产品的次品率，还能节省控制器的引脚资源。并且通过至少两条导线电连接也有效延长产品的使用寿命，进一步为用户节约开销。
参阅图5，图5为本发明触摸式显示装置一实施方式的结构示意图。本实施方式中的显示装置包括触控面板501以及液晶组件502，其中液晶组件包括第一基板5021以及第二基板5022以及置于第一基板5021与第二基板5022之间的液晶层（图中未示出）。需要说明的是，图5中触控面板501与液晶组件502之间的关系只是相对关系，根据电容式触摸式显示装置的不同类型，具有不同的位置关系，上述关系只是举例说明，并非限制。
本实施方式的触控面板为In-cell自容式触控面板。本实施方式中的触控面板包括多个矩阵排列的触控电极以及控制器。在本实施方式中，触控电极为纳米铟锡金属氧化物ITO电极。
其中，每个触控电极与控制器之间通过至少两根导线相连接。在本实施方式中，每个触控电极与控制器之间通过两根导线相连接。为了使整个触控面板更加简洁，电路更加清晰，在一个优选的实施方式中，两根连接同一触控电极与控制器的导线分别在所述触控电极所处的电路板的不同的层，如触控电极所处的电路板为4层板，一根导线可置于第一层，另一根导线则置于第四层等。
但是由于一般情况下，触控电极的分辨率比显示像素的分辨率，因此，触控面板的布线空间相对而言比较充足，因此，在另一个实施方式中，两根导线也可以同时处于所述触控电极所处的电路板相同的层，如电路板为4层时，两根导线可以同时处于电路板的第一层或者同时处于电路板的第四层。
为了节省控制器的引脚，减轻控制器的引脚负担，优选地，每个触控电极与控制器相连接的两根导线以及在控制器的引脚处汇聚到一根导线上，与控制器的同一个引脚电连接。
当所述触控面板工作时，每个触控电极分别与地形成自电容，控制器通过外加电源（图中未示出）实时的对每个触控电极进行扫描，即不停地通过两根导线中的任一根对触控电极进行充电和放电，当用户触摸到触控面板时，由于人属于导体，与触控面板本身也存在电容，影响了触控电极与地形成的自电容的电容值，通过确定电容值发生变化的触控电极的位置来确定用户触碰的位置。进一步地通过显示装置显示与触碰的位置图标或指令对应的显示内容。即使有单根导线出现故障，另外一根导线继续为触控电极与控制器传输信号，完全不影响触控面板的正常工作，又能节省控制器的引脚资源。
在另一个实施方式中，每个触控电极与控制器之间通过超过两条的导线相连接，如3根导线相连接。为了节省控制器的引脚，减轻控制器的引脚负担，优选地，每个触控电极与控制器相连接的三根导线在控制器的引脚处汇聚到一根导线上，与控制器的同一个引脚电连接。即时有单根导线出现故障，另外两根中任一一根根导线继续为触控电极与控制器传输信号，完全不影响触控面板的工作，而且节省控制器的引脚资源。
在其他实施方式中也可为4条，5条，甚至更多，且同一个触控电极的多根导线在控制器的引脚处均汇聚在一根导线上，与控制器的同一个引脚电连接，在此不做限定。由于增加导线的成本远远低于对触控面板的更换，因此，通过上述方式在不增加任何成本和工艺制程的情况下减少了触控电极与控制器之间由于导线出现故障而导致的对触控面板的工作的影响，有效提高了触控面板的工作效率，又能节省控制器的引脚资源。
需要说明的是，本实施方式中的触控面板为In-cell自容式触控面板，但是并不完全局限于In-cell自容式触控面板，其他类型的触控面板中的触控电极与控制器之间通过超过一条的导线与控制器相连接的方案均属于本发明保护的范围，在此不一一列举。
区别与现有技术，区别与现有技术，本实施方式中的触控面板包括控制器以及多个矩阵排列的触控电极，每个触控电极通过至少两条跳线与所述控制器的同一个引脚电连接。即使单根导线发生断路或其他异常现象，仍然能通过其他至少一条导线实现触控电极与控制器之间的电连接，有效减少断线等由于导线引起的异常现象，减少产品的次品率，还能节省控制器的引脚资源。并且通过至少两条导线电连接也有效延长产品的使用寿命，进一步为用户节约开销。
以上所述仅为本发明的实施方式，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。
