Description

一种触控面板及显示装置 技术领域
本发明涉及显示技术领域，尤其涉及一种触控面板及显示装置。
背景技术
触控屏(touch screen)又称为“触摸屏”，是目前最简单、方便、自然的一种人机交互方式。它赋予了多媒体以崭新的面貌，是极富吸引力的全新多媒体交互设备。
具体地，如图1所示，触控面板一般包括触控功能区21和线路绑定区22，触控功能区21一般设置有相互交错的多条触控传感电极Rx和多条触控驱动电极Tx。触控传感电极Rx和触控驱动电极Tx在线路绑定区22分别与线路绑定区22的连接电极20电连接，连接电极20与柔性线路板FPC(Flexible Printed Circuit board，柔性线路板)30等绑定连接。则当手指触控显示屏时，由触控传感电极Rx和触控驱动电极Tx通过连接电极将触控信号传输给柔性线路板FPC，以对触控信号进行处理，实现触控功能。
如图2所示，柔性线路板30设置有多条连接线31，用于将柔性线路板30与线路绑定区22的连接电极20绑定连接，主要是使得柔性线路板的连接线31与连接电极20接触电连接。然而，为了使得柔性线路板的连接线31与连接电极20、连接线31与柔性线路板30具有好的接触效果，触控面板在线路绑定区22处的连接电极20一般直接裸露在外，导致线路绑定区22上的连接电极20容易被空气中的水、氧等侵蚀，严重的可能会导致触控功能失效。
发明内容
本发明的实施例提供一种触控面板及显示装置，所述触控面板的连接电极不仅可以实现与线路板的良好电接触，还可以避免被空气中的水、氧等侵蚀。
本发明的实施例采用如下技术方案：
一方面，本发明实施例提供了一种触控面板，包括：线路绑定区，所述线路绑定区形成有多条连接电极，所述连接电极用于与线路板绑 定电连接；所述触控面板还包括保护层，所述保护层至少覆盖所述连接电极的一个侧面。
另一方面，本发明实施例提供了一种显示装置，包括本发明的各实施例中的任一实施例所提供的触控面板。
本发明的实施例提供一种触控面板及显示装置，在本发明实施例中，触控面板线路绑定区的保护层覆盖多条连接电极的侧面，保护层可以避免空气的水、氧等对连接电极的侵蚀，保证连接电极的性能，延长连接电极的寿命。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例提供了一种触控面板，包括：线路绑定区，其中，线路绑定区形成有多条连接电极，连接电极用于与线路板绑定电连接，触控面板还包括保护层，保护层至少覆盖连接电极的一个侧面。
在本发明的实施例中，线路绑定区的连接电极与柔性线路板电连接，用于通过连接电极向柔性线路板传输触控信号。其中，触控面板可以包括一个线路绑定区，或者针对大尺寸触控面板还可以设置有多个线路绑定区，本发明实施例仅以触控面板包括一个线路绑定区的情形为例进行详细说明。
其中保护层可以通过构图工艺形成，所谓“构图工艺”是将薄膜形成包含至少一个图案的层的工艺；构图工艺可包含：在薄膜上涂光刻胶，利用掩膜板对所述光刻胶进行曝光，再利用显影液将需去除的光刻胶冲蚀掉，再刻蚀掉未覆盖光刻胶的薄膜部分，最后将剩下的光刻胶剥离。应用于本发明实施例掩膜板可以在与触控面板线路绑定区对应的区域上包括透光图案和不透光图案，以用于形成该保护层。
其中，连接电极可以是由任何导体材料形成的，在本发明的实施例中，以金属连接电极作为连接电极，而金属连接电极的导电性能稳定，且电阻小。
在根据本发明的一个实施例中，连接电极的上表面与柔性线路板的连接线接触，触控面板线路绑定区的保护层可覆盖多条连接电极的一个侧面，则保护层可以避免空气的水、氧等对连接电极的侵蚀，保证连接电极的性能，延长连接电极的寿命。
如图3所示，在根据本发明的一个实施例中，保护层40覆盖连接电极20的两个侧面。即从两个侧面防止空气中水、氧等对连接电极的侵蚀。
在根据本发明的一个实施例中，保护层可覆盖多条连接电极中的每条连接电极的一个侧面或两个侧面，从而防止空气中水、氧等对每条连接电极的侵蚀。
在根据本发明的另一实施例中，保护层还覆盖连接电极的上表面的一部分，且连接电极的上表面被保护层覆盖的宽度不大于连接电极宽度的30％。在该实施例中，连接电极的宽度可大于柔性线路板的导电线(即，连接线)的宽度，保护层还可覆盖连接电极上表面的一部分，以防止连接电极不与柔性线路板的导电线接触的部分与空气接触。且为了保证连接电极与柔性线路板导电线具有足够的接触表面，保护层覆盖连接电极的宽度可不大于连接电极宽度的30％。例如，保护层覆盖连接电极的宽度可以是连接电极宽度的10％、15％或20％等。
下面以保护层覆盖连接电极宽度的10％为例进行详细说明。保护层覆盖连接电极宽度的10％，可以是仅在连接电极的上表面的一侧进行覆盖。柔性线路板的连接线可形成一排，并与相应的连接电极对应，进一步地，为了让每一条连接电极与柔性线路板上的对应的一条连接线接触电连接，如图4所示，在根据本发明的另一实施例中，连接电极20的上表面被保护层40覆盖的部分位于未被保护层覆盖部分的两侧。即连接电极20的上表面的两侧被保护层40覆盖，其中间部分裸露出来与柔性线路板的连接线31连接。进一步的，位于未被保护层覆盖部分的两侧的连接电极20的上表面的被保护层40覆盖的部分中的每个的宽度不大于连接电极宽度的5％，即由保护层所覆盖的部分的宽度不大于连接电极宽度的10％。具体的，如图4所示，假定单个的连接电极20的宽度为b，单个的连接电极20的上表面被保护层40覆盖的宽度为b-a，单个的连接电极20的上表面的两侧被保护层40覆盖的部分的宽度分别为c和d，则b-a≤0.1b，c≤0.05b，d≤0.05b。这样，在保护连接电极20不受侵蚀的情况下，最大地保留连接电极20与柔性线路板的连接线31之间的接触面积不被覆盖。在图4所示的实施例中，宽度a可以介于连接线31的宽度与单个的连接电极20的宽度之间。
根据本发明的实施例，触控面板还可包括触控功能区，触控功能区包括多条触控传感电极和触控驱动电极，触控传感电极和触控驱动电极与线路绑定区的连接电极电连接；在一个实施例中，保护层还可覆盖触控功能区的触控驱动电极和触控传感电极。触控驱动电极和触控传感电极一般为导电金属，则其与空气接触容易被氧化或腐蚀，让保护层覆盖触控驱动电极和触控传感电极，可避免它们被氧化或腐蚀而导致触控功能失效。且当保护层还覆盖触控驱动电极和触控感应电极时，仅需要在掩膜板的与触控功能区以及连接绑定区相对应的区域上设置相应的透光区域和遮光区域，可通过一次构图工艺形成同时覆盖触控功能区和连接绑定区的保护层。
当然，也可以在触控功能区单独形成一层用于保护触控驱动电极和触控传感电极的保护层，而利用线路绑定区的保护层直接覆盖触控驱动电极和触控传感电极，可以进一步减少构图工艺，简化制作步骤。
由于连接电极设置在线路绑定区，而线路绑定区对应显示面板的 非显示区域，所以，在一个实施例中，为了防止显示面板非显示区域漏光，连接电极的下面可形成有黑矩阵膜层。本发明各实施例中的“上”、“下”以制造薄膜或层结构等的先后顺序为准，例如，在上的薄膜是指相对在后形成的薄膜，在下的薄膜是指相对在先形成的薄膜。
本发明的另一实施例提供了一种显示装置，包括本发明前述各实施例中任一实施例提供的触控面板。所述显示装置可以为液晶显示器、电子纸、OLED(Organic Light-Emitting Diode，有机发光二极管)显示器等显示装置以及包括这些显示装置的电视、数码相机、手机、平板电脑等任何具有显示功能的产品或者部件。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所述权利要求的保护范围为准。
