Abstract

本发明公开了一种触控盖板。触控盖板包括：盖板主体，所述盖板主体具有位于盖板主体的按键区内的至少一个按键；和设置于所述盖板主体背面的用于所述按键的至少一个走线。所述走线配置为将所述按键连接到位于所述按键区之外的电路板。

Description

触控盖板及其制造方法和触控显示装置 技术领域
本发明涉及显示技术领域，特别涉及一种触控盖板及其制造方法和触控显示装置。
背景技术
内嵌式(IN-CELL)及外置式(ON-CELL)结构集成了外挂式触摸屏的触控功能，但此功能集成仅限于液晶显示器(Liquid Crystal Display，简称LCD)的显示区内。外挂式触摸屏按键部分没有集成触控功能。
目前，内嵌式及外置式的显示模组的功能按键的主要包括两种形式：一、LCD显示区用虚拟功能按键实现，盖板(Cover Glass，简称CG)上不设置按键；二、在CG的按键区背面设置柔性线路板(Flexible Printed Circuit，简称FPC)实现按键功能。
但是，现有技术的方案存在如下技术问题：若采用第一种形式设置功能按键时，由于功能按键占用了显示区，从而缩小了LCD屏幕的显示区；若采用第二种形式设置功能按键时，由于FPC自身具备一定的厚度(例如0.1mm)，增加了按键区的厚度，导致在结构上需要为FPC进行避空。

图1为根据本发明实施例的一种触控盖板的结构示意图；
图2为图1中盖板主体背面的局部结构示意图；
图3为图2中按键图案和按键走线的结构示意图；
图4是沿图3中的A-A线截取的局部剖视图；

具体实施方式
下面将结合附图详细地描述本发明的实施例.附图中的类似的附图标记指代类似的特征.本发明也可以其他不同形式实现,因此本文阐述的实施例不应当被解释为本发明的限制.提供这些实施例是为了使本领域技术人员能够充分和完全的理解本发明的构思.
一方面，图1示出了根据本发明实施例的一种触控盖板的结构示意图，图2为图1中盖板主体背面的局部结构示意图，图3为图2中按键图案及按键走线的结构示意图，如图1、图2和图3所示，该触控盖板包括盖板主体1，所述盖板主体具有位于盖板主体的按键区内的至少一个按键；和设置于所述盖板 主体背面的用于所述按键的至少一个走线3。所述走线配置为将所述按键连接到位于所述按键区域之外的电路板。
在示例性的实施例中，所述按键可以是下压式按键，也可以是触控按键。当按键是下压式按键时，走线3的一端可位于按键1的下方，当按键1被按压时与走线3连接。
当按键是触控按键时，走线3的一端可直接连接到触控按键。具体地，在一个示例性的实施例中，所述按键为触控按键，所述触控盖板还包括设于位于所述盖板主体背面的按键图案2，按键图案2与走线3连接。
如图1所示，盖板主体1包括显示区11和按键区12，按键区12位于显示区11的下方。按键图案2和按键走线3位于按键区12中。由于按键图案2和走线3均位于盖板主体1的背面，因此按键图案2和走线3在图1中未具体示出。
图1中示出了盖板主体1的正面，该盖板主体1的正面为用户使用该触控显示装置时朝向用户的一面，即：该盖板主体1的正面为背向触控显示装置内部的一面；图2中示出了盖板主体1的背面，该盖板主体1的背面为用户使用该触控显示装置时背向用户的一面，即：该盖板主体1的背面为朝向触控显示装置内部的一面。
为了能够清楚表示出走线3，图3中示出了部分主要的走线3，从图3中可以清楚的看出，走线3和按键图案2连接。
按键图案2的数量可以为一个或者多个(例如，3个，如图2和图3所示)。每个功能按键图案2均与对应的走线3连接。如图2和图3所示，走线3围绕按键图案2设置。
本实施例中，按键图案2的厚度为0.01mm至0.06mm，优选地，按键图案2的厚度为0.04mm。由于按键图案2的厚度较薄，从而在结构上可做到不与其它部件干涉。
如图2和图3所示，走线3的第一端与按键图案2连接，走线3的第二端 与绑定于盖板主体1背面的电路板的第一端连接。需要说明的是，电路板可以是各种类型的电路板，例如可以是在电子产品中常用的柔性电路板4。本发明是以柔性电路板为例进行说明的。
本实施例中，柔性线路板4的第一端绑定于盖板主体1的背面，具体地，柔性线路板4的第一端绑定于按键区12中。按键区12中设置有搭接区5，走线3的第二端与柔性电路板4的第一端连接于搭接区5中，搭接区5可位于按键图案2的一侧，则走线3的第二端位于按键图案2的一侧。例如，在图2和图3中，搭接区5位于按键图案2的右侧，因此，走线3的第二端也位于按键图案2的右侧。可选地，在未示出的实施例中，搭接区5和走线3的第二端也可以位于按键图案2的左侧。在另一未示出的实施例中，还可在按键图案的两侧均设置搭接区，同时一部分走线的第二端连接到位于一侧的第一搭接区，另一部分按键走线的第二端连接到位于另一侧的第二搭接区。相应地，可提供分别连接到所述两个搭接区的两个柔性线路板。
柔性线路板4的第一端设置有第一连接图形，走线3的第二端设置有第二连接图形，第一连接图形和第二连接图形在搭接区5内彼此连接。在示例性的实施例中，可通过各向异性的导电胶膜(Anisotropic Conductive Film，简称ACF)对第一连接图形和第二连接图形进行压合以使第一连接图形和第二连接图形连接，从而实现将柔性线路板4和走线3在搭接区5进行连接。第一连接图形和第二连接图形的材料例如可均为金属。柔性线路板4的第二端设置有柔性线路板4的连接区6。连接区6可用于与主板直接连接或者通过内嵌式或外置式模组与主板连接，从而实现柔性线路板4与主板之间的电连接。从而按键走线3可通过柔性线路板4引出。
在实际应用中，根据产品设计需要，走线3可以同层设置或者不同层设置。当走线3不同层设置时，不同层的走线3之间需设置有绝缘层。不同层的走线3之间可以采用架桥的方式进行设置。
本实施例中，该触控盖板还包括：第一油墨层18，第一油墨层18位于盖 板主体1的背面，第一油墨层位于盖板主体1和按键图案2之间，且第一油墨层18位于盖板主体1和走线3之间。本实施例中，由于按键图案2和走线3同层设置，因此第一油墨层18可位于盖板主体1与按键图案2和走线3所在层之间，如图4所示。
本实施例中，该触控盖板还包括：第一绝缘层10，第一绝缘层10位于第一油墨层18和按键图案2之间，且第一绝缘层10位于第一油墨层18和走线3之间。本实施例中，由于按键图案2和走线3同层设置，因此第一绝缘层10位于第一油墨层18与按键图案2和走线3所在层之间，如图4所示。
本实施例中，该触控盖板还包括：第二油墨层19，第二油墨层19位于按键图案2和走线3的上方，本实施例中，由于按键图案2和走线3同层设置，因此第二油墨层19位于按键图案2和走线3所在层的上方，如图4所示。
本实施例中，该触控盖板还包括：第二绝缘层7，第二绝缘层7位于按键图案2和第二油墨层19之间，且第二绝缘层7位于走线3和第二油墨层19之间，本实施例中，由于按键图案2和走线3同层设置，因此第二绝缘层7位于按键图案2和走线3所在层与第二油墨层19之间，如图4所示。
本实施例中，该触控盖板还包括：与触控按键图案2对应的触控按键标识8，该触控按键标识8位于盖板主体1的背面，并且其从盖板主体1的正面是可见的，用户可根据触控按键标识8进行相应的按键操作。例如：该触控按键标识8可包括主页标识或者返回标识。触控按键标识8与触控按键图案2一一对应设置，因此图3中示出了三个触控按键标识8在盖板主体1背面对应的位置。本实施例中，按键图案2和触控按键标识8组成功能按键，换言之，功能按键包括按键图案2和触控按键标识8，其中，按键图案2为具备按键功能的部件，而触控按键标识8仅具有标识功能而不具备按键功能。
功能按键可以为不透光按键或者不透光按键，因此按键图案2可以为透光的按键图案或者不透光的按键图案。在示意性的实施例中，按键图案2为透光按键图案，并且按键图案2具有开窗区域21，该开窗区域21可透过光源发出 的光线。相应地，第一油墨层8上与开窗区域21对应的位置设置有第一开口区域；第二油墨层9上与开窗区域21对应的位置设置有第二开口区域，使得光源发出的光线能够穿过所述第一开口区域和第二开口区域，而透射至开窗区域21。综上所述，光源发出的光线依次透过第二油墨层上的第二开口区域、按键图案2的开窗区域21和第一油墨层上的第一开口区域，从而实现了功能按键为透光按键。其中，优选地，触控按键标识8可与开窗区域21对应设置。
本实施例提供的触控盖板中，通过在盖板主体的背面设置按键图案和走线，可避免采用虚拟的功能按键时功能按键占用显示区的问题，从而增大了屏幕的显示区；同时，盖板主体的背面无需设置柔性线路板，减小了盖板主体的按键区的厚度，从而在结构上节省了用于柔性线路板的空间。
另一方面，提供了一种触控显示装置。根据示例性的实施例，该触控显示装置包括：显示面板、触控盖板和触控电路，触控盖板设置于显示面板上。本实施例中，触控盖板可采用根据上述任一实施例的触控盖板，因此省略关于触控盖板的说明。走线与触控电路连接。
可选地，该触控盖板还可包括：柔性线路板，柔性电路板的第一端绑定于盖板主体的背面，走线的第一端与按键图案连接，走线的第二端与柔性电路板的第一端连接，柔性电路板的第二端与触控电路连接，使得走线通过柔性电路板与触控电路电连接。
本实施例中，触控显示装置可以为内嵌式触控显示装置或者外置式触控显示装置。
本实施例提供的触控显示装置中，通过在盖板主体的背面设置按键图案和走线，可避免采用虚拟的功能按键时功能按键占用显示区的问题，从而增大了屏幕的显示区；同时，盖板主体的背面无需设置柔性线路板，减小了盖板主体的按键区的厚度，从而在结构上节省了用于柔性线路板的空间。
在本申请的又一方面中，提供了一种触控盖板的制造方法。图4示出了该制造方法的流程图。该方法包括：
步骤101：在盖板主体的背面形成触控按键标识。
步骤102：在盖板主体的背面形成至少一个走线，其中，所述盖板主体具有位于盖板主体的按键区内的至少一个按键，所述走线被形成为将所述按键连接到位于所述按键区之外的电路板。
在示例性的实施例中，所述按键包括触控按键，所述触控盖板还包括设于位于所述盖板主体背面的按键图案，并且按键图案和走线位于按键区中。触控按键标识和按键图案对应。
在该实施例的情况下，步骤102可包括：通过丝印(screen printing)、曝光或者黄光工艺(yellow light process)在盖板主体的背面形成按键图案和走线。其中，当采用丝印工艺时，走线为丝印银浆走线或者丝印铜走线；当采用曝光工艺时，走线为曝光银浆走线；当采用黄光工艺时，走线为黄光ITO走线。
本实施例中，走线的第一端与按键图案连接。
进一步地，该方法还可包括以下步骤：
在形成按键图案及按键走线之前，在盖板主体的背面形成第一油墨层，以及在第一油墨层之上形成第一绝缘层；
在按键图案和走线之上形成第二绝缘层；
将柔性线路板绑定于盖板主体的背面，以使走线的第二端与柔性电路板的第一端连接，柔性电路板的第二端与触控电路连接；和
在第二绝缘层之上形成第二油墨层。
在示例性的实施例中，第一绝缘层和第二绝缘层可通过丝印或者黄光工艺形成，使得第二绝缘层覆盖按键图案和按键走线。
利用上述制造方法可制造任一上述实施例所述的触控盖板。触控盖板的结构及描述已于上文中阐述，此处不再赘述。
本实施例提供的触控盖板的制造方法制造出的触控盖板中，通过在盖板主体的背面设置按键图案和走线，可避免采用虚拟的按键时按键占用显示区的问题，从而增大了屏幕的显示区；同时，盖板主体的背面无需设置柔性线路板， 减小了盖板主体的按键区的厚度，从而在结构上节省了用于柔性线路板的空间。
尽管已经结合附图示出并描述了多个示例性的实施例,但本领域技术人员将会意识到,可以在不背离本发明的原理和实质的前提下对这些实施例作出各种修改和变化,因此,本发明的范围应由所附权利要求及其等同技术方案限定.
