Description

触控显示模组及触控显示装置 技术领域
本发明涉及显示技术领域，尤其涉及一种触控显示模组及触控显示装置。
 背景技术
触控面板主要采用手指触控和触控笔触控两种方式，其中，触控笔主要有电容笔和电磁笔两种，就书写效果而言，电磁笔比电容笔的书写效果更好，在专业绘画、工业设计和服装设计等专业领域广泛应用。
现有的支持电磁笔的触控屏是通过在显示模组背面组装贴合电磁感应(Elector-Magnetic Resonance, EMR)模组或EMR天线板来实现电磁触控的，其中，EMR模组或EMR天线板是由横纵交错的金属线构成，当电磁笔在触控屏上移动时，内置共振电子或线圈因电磁感应会积蓄到微弱的电量，电磁笔和触控屏的感应线圈之间产生电磁感应信号，根据电磁感应信号的变化可以计算出触控笔的坐标、倾斜度和操作状态。
 技术问题
目前，除了对手指触控的要求越来越高，对触控笔的要求也越来越高，而若想要兼容电容笔和电磁笔，采用目前的背面组装贴合EMR模组或EMR天线板的方式会增加触控屏的厚度，且增大了触控屏的功耗和制造成本，虽然也有部分方案是将电磁触控线圈集成于触控屏内部，但是为了制作方便，通常是将电磁触控线圈和电容触控电极设置于同一层，而由于同一层的空间有限，对于制造工艺的要求较高，且对于电磁触控线圈和电容触控电极的感应互相会造成干扰，这在一定程度上无法将手指或电容笔的触控效果和电磁笔的触控效果均发挥到最佳效果，因此有必要提出一种兼容电容笔和电磁笔，并能将电容笔和电磁笔的触控效果达到最佳，且不会增加产品厚度、功耗和制造成本的触控屏。

 本发明的实施方式
为使本申请的目的、技术方案及效果更加清楚、明确，以下参照附图并举实施例对本申请进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
如图1所示，本发明实施例提供一种触控显示模组，包括异层设置的触控层10和柔性基底20；触控层10包括电容触控电极，电容触控电极用于确定手指或电容笔的平面坐标；柔性基底20包括电磁触控线圈，电磁触控线圈用于确定电磁笔的平面坐标。
具体地，本发明实施例提供的触控显示模组的膜层结构包括设置于不同层的触控层10和柔性基底20，将用于感应手指或电容笔的动作，从而确定手指或电容笔的平面坐标的电容触控电极设置于触控层10中，并将用于感应电磁笔的动作，从而确定电磁笔的平面坐标的电磁触控线圈设置于柔性基底20中，由此将电磁触控电极集成于触控显示模组中，且电磁触控电极与电容触控电极位于不同层，使得触控显示模组在兼容电容触控和电磁触控的同时，电磁触控和电容触控之间可以互不干扰，并且与现有技术采用背贴式电磁感应模组相比，减小了触控显示模组的厚度，也不会增加功耗和制造成本。
需要说明的是，为了增大触控显示模组的开口率，电容触控电极和电磁触控线圈的材料均采用透明的氧化铟锡。
如图3所示，在一些实施例中，电容触控电极包括沿第一方向延伸的第一电容触控电极110和沿第二方向延伸的第二电容触控电极120，第一方向和第二方向互相垂直；其中，第一电容触控电极110和第二电容触控电极120中的一种为发送电极，另一种为接收电极。
具体地，若第一方向为X方向，第二方向为Y方向，触控层10包括图案化的多个沿Y方向排布的第一电容触控电极110和多个沿X方向排布的第二电容触控电极120，第一电容触控电极110和第二电容触控电极120之间通过间隔设置的多个电容连接电极1001互相连接。当触控层10采用互容式触控时，第一电容触控电极110和第二电容触控电极120的相交处形成互电容，当手指或电容笔触摸到触控显示模组时，影响了互电容附近的第一电容触控电极110和第二电容触控电极120之间的耦合，从而改变了互电容的电容值大小。检测互电容的电容值大小时，可将第一电容触控电极110作为发送电极输出激励信号，将第二电容触控电极120作为接收电极接收信号，这样可以得到互电容的电容值大小，从而确定手指或电容笔的触控点的平面坐标。
需要说明的是，本发明实施例的触控层10还可以采用自容式触控，即电容触控电极接地，分别检测第一电容触控电极110和第二电容触控电极120的电容变化量，从而分别确定触控点的X坐标和Y坐标，最后确定触控点的平面坐标。
如图4所示，在一些实施例中，电磁触控线圈包括沿第一方向延伸并形成回路的第一电磁触控线圈200，以及沿第二方向延伸并形成回路的第二电磁触控线圈210，第一方向和第二方向互相垂直；其中，第一电磁触控线圈200和第二电磁触控线圈210中的一种为发送线圈，另一种为接收线圈。
具体地，若第一方向为X方向，第二方向为Y方向，柔性基底20包括图案化的多个沿X方向延伸并形成回路的第一电磁触控线圈200和多个沿Y方向延伸并形成回路的第二电磁触控线圈210，即，每个第一电磁触控线圈200包括两条沿X方向设置的第一电磁触控电极2001以及沿Y方向设置的用于连接这两条第一电磁触控电极2001的第一电磁连接电极2002，每个第二电磁触控线圈210包括两条沿Y方向设置的第二电磁触控电极2101以及沿X方向设置的用于连接这两条第二电磁触控电极2101的第二电磁连接电极2102。第一电磁触控线圈200和第二电磁触控线圈210之间互相绝缘，可以将第一电磁触控线圈200作为发送电极输出激励信号，并将第二电磁触控线圈210作为接收线圈接收信号，这样通过第一电磁触控线圈200和第二电磁触控线圈210与电磁笔之间的电磁感应信号确定电磁笔的平面坐标。
进一步地，如图2所示，在一些实施例中，该触控显示模组还包括设置于触控层10和柔性基底20之间的封装层30和发光层40，其中，封装层30设置于触控层10靠近柔性基底20的一侧，发光层40设置于柔性基底20靠近触控层10的一侧。
另外，该触控显示模组还包括依次设置于触控层10上方的上偏光片60、液态光学胶70和盖板80，以及设置于柔性基底20下方的超净泡沫复合膜50，其中，盖板80和上偏光片60通过液态光学胶70相互贴合，超净泡沫复合膜50能够对作用于触控显示模组的应力起到缓冲作用，且能够散发触控显示模组工作时产生的热量，对触控显示模组起到一定的保护效果。
进一步地，如图5-图9所示，在一些实施例中，柔性基底20包括异层设置的第一柔性衬底层201和第二柔性衬底层202；第一电磁触控线圈200和第二电磁触控线圈210分别设置于第一柔性衬底层201和第二柔性衬底层202；或者，第一电磁触控线圈200和第二电磁触控线圈210均设置于第一柔性衬底层201或第二柔性衬底层202。
具体地，第一电磁触控线圈200和第二电磁触控线圈210可以异层设置，也可以同层设置，即，当柔性基底20包括异层设置的第一柔性衬底层201和第二柔性衬底层202时，如图5或图6所示，第一电磁触控线圈200和第二电磁触控线圈210可以分别设置于第一柔性衬底层201和第二柔性衬底层202中的一层，或者，如图7或图8所示，第一电磁触控线圈200和第二电磁触控线圈210均设置于第一柔性衬底层201或第二柔性衬底层202。
需要说明的是，第一柔性衬底层201和第二柔性衬底层202之间互相绝缘，从而可以保证第一电磁触控线圈200和第二电磁触控线圈210分别设置于第一柔性衬底层201和第二柔性衬底层202中的一层时，第一电磁触控线圈200和第二电磁触控线圈210之间可以互相绝缘。
还需要说明的是，当第一电磁触控线圈200和第二电磁触控线圈210同层设置时，为了保证第一电磁触控线圈200和第二电磁触控线圈210之间互相绝缘，在第一电磁触控线圈200和第二电磁触控线圈210的相交处需要设置金属桥230，金属桥230与第一电磁触控线圈200和第二电磁触控线圈210异层设置，用于跨接连接第一电磁触控线圈200和第二电磁触控线圈210。
基于此，如图7所示，第一电磁触控线圈200和第二电磁触控线圈210均设置于第一柔性衬底层201，金属桥230设置于第二柔性衬底层202，或者，如图8所示，第一电磁触控线圈200和第二电磁触控线圈210均设置于第二柔性衬底层202，金属桥230设置于第一柔性衬底层201。
在一些实施例中，柔性基底20还包括与第一柔性衬底层201和第二柔性衬底层202异层设置的底部屏蔽金属层203，金属桥230还可以设置于底部屏蔽金属层203；第一电磁触控线圈200和第二电磁触控线圈210均设置于第一柔性衬底层201或第二柔性衬底层202，金属桥230设置于底部屏蔽金属层203。
需要说明的是，由于底部屏蔽金属层203的空间有限，因此仅适合设置金属桥，不适合设置图案复杂的电磁触控线圈。如图9所示，当金属桥230设置于底部屏蔽金属层203，且第二柔性衬底层202设置于底部屏蔽金属层203和第一柔性衬底层201之间时，若第一电磁触控线圈200和第二电磁触控线圈210共同设置于第一柔性衬底层201，则金属桥230需要跨过第二柔性衬底层202才能与设置于第一柔性衬底层201的第一电磁触控线圈200和第二电磁触控线圈210连接，导致金属桥230与电磁触控线圈之间的间距较大，以致于第一电磁触控线圈200和第二电磁触控线圈210之间的绝缘容易失效，因此，当金属桥230设置于底部屏蔽金属层203，且第二柔性衬底层202设置于底部屏蔽金属层203和第一柔性衬底层201之间时，第一电磁触控线圈200和第二电磁触控线圈210共同设置于第二柔性衬底层202较好，此时金属桥230与第一电磁触控线圈200和第二电磁触控线圈210之间的间距较小，从而能保证第一电磁触控线圈200和第二电磁触控线圈210之间的绝缘良好。也就是说，当金属桥230设置于底部屏蔽金属层203时，第一电磁触控线圈200和第二电磁触控线圈210优选设置于与底部屏蔽金属层203距离相近的柔性衬底层中。
进一步地，如图5-图9所示，本发明实施例中，第一柔性衬底层201和第二柔性衬底层202之间还设置有第一间隔层204，第一柔性衬底层201和底部屏蔽金属层203之间还设置有光阻剂层205，底部屏蔽金属层203上方还设置有第二间隔层206。
基于上述实施例，电磁触控线圈和金属桥均采用相应的光罩制备而成，若第一电磁触控线圈200和第二电磁触控线圈210分别设置于第一柔性衬底层201和第二柔性衬底层202，则第一电磁触控线圈200和第二电磁触控线圈210采用两道不同的光罩制成；若第一电磁触控线圈200和第二电磁触控线圈210均设置于第一柔性衬底层201或第二柔性衬底层202，则第一电磁触控线圈200和第二电磁触控线圈210采用同一道光罩制备而成，金属桥230采用另一道光罩制备而成。
基于上述实施例，本发明实施例还提供一种触控显示装置，包括如上所述的触控显示模组，该触控显示装置与该触控显示模组具有相同的结构和有益效果，由于上述各实施例已经对该触控显示模组进行了详细的描述，此处不再赘述。
可以理解的是，对本领域普通技术人员来说，可以根据本申请的技术方案及其发明构思加以等同替换或改变，而所有这些改变或替换都应属于本申请所附的权利要求的保护范围。
