具体实施方式
本发明实施例公开了一种终端，用于解决现有技术中实现压力触控所存在的成本高的问题，节约成本。
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，本领域技术人员在没有作出创造性劳动前提下所获取的所有其他实施例，都属于本发明保护的范围。
本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”“第四”等是用于区别不同的对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、***、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
本发明的技术方案，应用于任何终端，比如智能手机、ipad和个人电脑等，此处不做具体限定。
其中，该终端可以是携带有触摸屏的终端，也可以是携带有按键按钮的终端，此处不做具体限定，如图1所示，进一步介绍终端的大概结构：
终端100包括盖板101，在盖板101的下方为显示模组102，其中，该盖板101和显示模组102之间可通过光学透明胶(英文全称：optical clear adhesive，缩写：OCA)粘结，在显示模组102的下方为金属中框103，其中，金属中框103接地，具体的，金属中框可以与***地连接，金属中框接地，因此金属中框103的电压值一直是0伏，其中，显示模组102与金属中框103之间存在一定的间隙，该间隙的大小在0.3mm左右。在显示模组里面的背光单元的下方也存在一定的间隙。另外，盖板101与显示模组102之间还可以设置有触摸模组，比如外挂式的终端就在盖板与显示模组之间设置有触摸模组，此处不做具体限定。
下面对本发明涉及到的几个名词进行解释：
盖板，具体的盖板101可以为玻璃盖板(Cover Glass)，该玻璃盖板也可 以叫做触摸屏盖板，是用来封闭或者盖住终端的显示模组的部件，其中，盖板主要是由玻璃材质制成，其厚度规格在0.1mm到1.1毫米之间。当然，盖板也可以由其他材质制成，此处不做具体限定。
显示模组，是组成显示屏成品的主要部件之一，主要由背光单元，基板以及驱动电路，电阻，电容和塑料套件等组成。
金属中框，是用来承载显示模组等器件的部件，由金属材质制成，比如铝制金属中框。
由于现有技术中是将专用的压阻材料集合在压力传感器上，从而利用专用独立的压力传感器布置LCD下方的四个角落，该专用的压阻材料成本高，而且需要开发新的供应商才能进行资源整合，整合成本也高。而本发明中，不需要利用专用独立的压力传感器布置LCD下方的四个角落，主要是利用显示模组与金属中框之间存在的间隙或者显示模组里面的背光单元下方的间隙，并利用现有的导电材料形成电容器，从而通过检测形成的电容器的电容变化实现压力触控，具体结构如下：
请参阅图2，本发明实施例中一种终端200的一个实施例，终端200包括：包括盖板201、显示模组202和金属中框203，其中，所述显示模组202位于所述盖板201和所述金属中框203之间，所述金属中框203接地，所述终端200还包括：
导电层204，所述导电层204贴合于所述显示模组202的下表面2020；
如图2所示，可以理解的是，从终端顶层到终端底层的垂直方向上看，显示模组的上表面与盖板贴合，而导电层与显示模组的下表面贴合。
与现有技术不同的是，本发明实施例中导电层所需的材料比较普遍，只需要具有导电性即可，因此，可以有效利用现有的一些导电材料，而不需要专用的压力材料，从而在很大程度上节约了材料成本。
在实际应用中，导电模组与金属终端之间存在大小为0.3mm左右的间隙，导电层的厚度在0.1mm左右，那么，进一步，将导电层贴合在显示模组的下表面。
在实际应用中，一般是通过框胶或者整面胶体将导电层贴合在显示模组的下表面，在有些情况下，如图2-a所示，只需要通过框胶将导电层固定在显示 模组的下方，在有些情况下，如图2-b所示，为了保证导电层的平整度以及导电层的导电性能的稳定性，可通过整面胶体(如图2-b中导电层与显示模组之间的部分)将导电层贴合在显示模组的下表面另外，该胶体可以是双面胶或者OCA胶体等，具体可根据实际情况进行选择，此处不做具体限定。
如图2所示，所述导电层204和所述金属中框203之间存在至少一个间隙(如图2中导电层与金属中框之间的区域)，其中，所述导电层204、所述金属中框203和所述至少一个间隙形成至少一个电容器，其中，所述至少一个电容器的电容变化反应出作用于所述盖板201上的至少一个压力的大小。
可以理解的是，导电层、金属中框和至少一个间隙形成至少一个电容器，导电层可看作电容器的一个极板，金属中框可看作电容器的另一个极板，该电容器可作为压力感应器，比如：用户在盖板上按压时产生一定的力，力的作用导致导电层发生形变，使得电容器的两个极板之间的距离发生改变，从而电容器的电容发生变化，进一步可通过电容器的电容的变化反映出作用在盖板上的压力的大小，比如，该结构的电容器作为压力感应器，可以感应出从轻按到重压之间的6万阶的压力，从而可以识别出不同阶的压力，而现有技术中只能识别出轻按与重压这两种阶的力。
可以理解的是，电容器的电容的变化与压力的大小成正比例关系，比如，电容器的电容的变化越大，则反应出作用于所述盖板上的压力越大，或者作用于所述盖板上的压力越大，则导致电容器的电容的变化越大。
在图2所示实施例的基础上，在一些可选的实施例中，如图3和图4所示，其中，所述导电层的下表面或者所述金属中框的上表面贴合至少一个弹性胶体。
如图3所示，为终端300的结构示意图，将所述导电层204的下表面2040贴合有至少一个弹性胶体205。
可以理解的是，导电层的上表面与显示模组贴合，可以避免导电层的形变量太大，在导电层的下表面贴合至少一个弹性胶体，其中，该弹性胶体一方面起到弹性压缩的作用，一方面起到粘结的作用。该弹性胶体可以是泡棉等，此处不做具体限定。
如图4所示，为终端400的结构示意图，将所述金属中框203的上表面 2030贴合有至少一个弹性胶体205。
可以理解的是，金属中框与导电层之间还存在一定的间隙，那么避免导电层的形变量太大，在金属中框的上表面贴合有至少一个弹性胶体。
在实际应用中，为了避免导电层的形变量太大而使得导电层贴合在金属中框上而无法实现压力触控，在导电层的下表面或者金属中框的上表面贴合有至少一个弹性胶体，其中，该弹性胶体可以为任意具有弹性压缩的胶体，该弹性胶体一方面具有弹性伸缩的作用，另一方面具有粘结的作用。
本发明实施例中，由于导电层与金属中框之间彼此绝缘，而且，导电层与金属中框之间还存在一定的间隙，该间隙的深度一般在0.2mm左右，从而利用导电层，金属中框、导电层与金属中框之间的至少一个间隙形成至少一个电容器，进一步，通过至少一个电容器的电容变化可以反映出作用于盖板上的至少一个压力的大小，比如当用户通过手指按压终端的触摸屏盖板时，用户施加了一定的压力在触摸屏盖板上，用户施加的压力导致电容器的电容发生改变，其中，该电容器的电容变化可以反应出作用于盖板上的至少一个压力的大小，进一步，终端可以接收到电容器的电容变化的信号，从而执行相应的操作，比如将终端的音量调高或者调低等。
与现有技术不同的是，由于导电层所需的导电材料都是现有的，而无需采用专用的压力材料，因此，不需要开发新的供应商进行资源整合就可实现压力触控，从而减少整合成本。
在图2、图3以及图4所示实施例的基础上，进一步请参阅图5，为终端500的一个结构示意图，其中，所述导电层204至少包括第一导电块2041和第二导电块2042，所述第一导电块2041和所述第二导电块2042连接；
可以理解的是，将第一导电块与第二导电块连接后，第一导电块与第二导电块之间实现电路连通，因此第一导电块与第二导电块可以共用终端的供电模组，比如，第一导电块从终端的供电模组获取电能后，第二导电块可以直接从第一导电块获取电能，而无需再连接于终端的供电模组的电路，从而减少电路的布设空间。将导电层和金属中框以及它们之间的电介质整体作为一个电容器时，由于终端的屏幕一般较大，为了达到较好的检测压力的效果，导电层的大小可以与终端的屏幕大小相当，因此导电层的横截面积也较大，导电层的横截 面积越大，越难做到较好的平整度检测，那么当外力作用于终端的盖板时，对电容器电容变化的检测的困难也相应的增加，那么通过检测电容器的电容的变化反映出压力的变化，对应的算法也将比较困难，因而，将导电层分为第一导电块和第二导电块后，针对每一个导电块做电容检测的难度将会下降，通过检测电容器电容的变化反映出压力的变化的算法也容易实现。另外，将第一导电块与第二导电块连接后，可作为一个整体，更方便整体检测电容器的电容变化。
在一些可选的实施例中，金属中框与导电层之间还存在一定的间隙，那么避免导电层的形变量太大，在金属中框的上表面贴合有至少一个弹性胶体，比如与第一导电块对应的第一弹性胶体，与第二导电块对应的第二弹性胶体等，此处不做具体限定。
在一些可选的实施例中，导电层的上表面与显示模组贴合，那么避免导电层的形变量太大，在导电层的下表面贴合至少一个弹性胶体，比如与第一导电块对应的第一弹性胶体，与第二导电块对应的第二弹性胶体等，此处不做具体限定。其中，该弹性胶体一方面起到弹性压缩的作用，一方面起到粘结的作用。该弹性胶体可以是泡棉等，此处不做具体限定。
与现有技术不同的是，将导电层分为不同导电块，其中，各个导电块之间的模式可以为自容式，也可以为互容式，终端可以识别出作用于盖板上的压力的位置点所对应的在导电块的位置点。另外，作用在盖板上的力引起整个导电层的变形，而导电层在各个位置点的变形程度也不相同，因此，可感应出不同电容器的电容的变化。
需要说明的是，导电层的材质为氧化铟锡(英文全称：Indium Tin Oxide，缩写：ITO)膜或铜箔柔性电路板(英文全称：Flexible Printed Circuit，缩写：FPC)，当然，也可以是其他具有导电性的材质，此处不做具体限定。
本实施例中，导电层可包括多个导电块，其中，各个导电块之间可以互相连接，也可以不连接，此处不做具体限定，其中，以第一导电块和第二导电块连接为例，下面进一步介绍第一导电块与第二导电块：

本发明实施例中，第一导电块，金属中框以及第一间隙形成第一电容器，第二导电块，金属中框以及第二间隙形成第二电容器，由于第一导电块与第二导电块连接，因此，第一电容器和第二电容器的电容变化反应出作用于盖板上的第一压力的大小，比如：单指按压触摸屏盖板时，单指施加的压力可导致第一电容器和第二电容器的电容发生变化，从而第一电容器和第二电容器的电容变化可以反应出作用于触摸屏盖板上的单指按压的压力的大小。
在图2、图3以及图4所示实施例的基础上，进一步请参阅图6，为终端600的一个结构示意图，其中，导电层204至少包括第三导电块2043和第四导电块2044；所述第三导电块2043与所述第四导电块2044不连接；
与现有技术不同的是，将导电层分为不同导电块，其中，各个导电块之间的模式可以为自容式，也可以为互容式，终端可以识别出作用于盖板上的压力的位置点所对应的在导电块的位置点。另外，作用在盖板上的力引起整个导电层的变形，而导电层在各个位置点的变形程度也不相同，因此，可感应出不同电容器的电容的变化，另外，导电块的数量与终端的屏幕所划分的区域的个数 对应。
需要说明的是，导电层的材质为ITO膜或FPC，当然，也可以是其他具有导电性的材质，此处不做具体限定。

在一些可选的实施例中，金属中框与导电层之间还存在一定的间隙，那么避免导电层的形变量太大，在金属中框的上表面贴合有至少一个弹性胶体，比 如与第三导电块对应的第三弹性胶体，与第四导电块对应的第四弹性胶体等，此处不做具体限定。
本发明实施例中，第三导电块，金属中框以及第三间隙形成第三电容器，第四导电块，金属中框以及第四间隙形成第四电容器，由于第三导电块与第四导电块不连接，因此，第三电容器的电容变化反应出作用于盖板上的第二压力的大小，第四电容器的电容变化反应出作用于盖板上的第三压力的大小，比如：双指按压触摸屏盖板时，双指中的第一指作用于第一导电块对应的盖板的第一区域，双指中的第二指作用于第二导电块对应的盖板的第二区域，第一指产生的压力使得第三电容器的电容发生变化，第二指产生的压力使得第四电容器的电容发生变化，从而第三电容器的电容变化可以反应出作用于触摸屏盖板上的双指中第一手指按压的压力的大小，第四电容器的电容变化可以反应出作用于触摸屏盖板上的双指第二手指按压的压力的大小。可见，将第一导电块与第二导电块不连接，可以实现多指压力触控，有效提高了用户体验。

所述导电层504和所述显示模组502的下表面52之间存在至少一个间隙(如图中显示模组的下表面与导电层之间的空白区域)，其中，所述显示模组502的下表面52为金属材质，所述显示模组502的下表面52接地，所述导电层504、所述显示模组502的下表面52和所述至少一个间隙形成至少一个电容器，即：导电层看做电容器的一个极板，显示模组的下表面看做电容器的另一个极板，其中，所述至少一个电容器的变化反应出作用于所述盖板501上的至少一个压力的大小。
其中，所述导电层504的材质为氧化铟锡ITO膜或铜箔柔性电路板FPC。
本发明实施例中，由于导电层与显示模组的下表面之间彼此绝缘，而且，导电层与显示模组的下表面之间还存在一定的间隙，该间隙的深度一般在0.2mm左右，从而利用导电层，显示模组的下表面、导电层与显示模组的下表面之间的至少一个间隙形成至少一个电容器，即：导电层看做电容器的一个极板，显示模组的下表面看做电容器的另一个极板，进一步，通过至少一个电容器的电容变化可以反映出作用于盖板上的至少一个压力的大小，比如当用户通过手指按压终端的触摸屏盖板时，用户施加了一定的压力在触摸屏盖板上，力的作用导致导电层发生形变，使得电容器的两个极板之间的距离发生改变， 从而导致电容器的电容发生改变，其中，该电容器的电容变化可以反应出作用于盖板上的至少一个压力的大小，进一步，终端可以接收到电容器的电容变化的信号，从而执行相应的操作，比如将终端的音量调高或者调低等。
与现有技术不同的是，由于导电层所需的导电材料都是现有的，而无需采用专用的压力材料，因此，不需要开发新的供应商进行资源整合就可实现压力触控，从而减少整合成本。
在图15所示实施例的基础上，请参阅图16，为终端1600的一个结构示意图，其中，所述导电层504包括至少包括第一导电块5041和第二导电块5042，所述第一导电块5041和所述第二导电块5042连接；
可以理解的是，将第一导电块与第二导电块连接后，第一导电块与第二导电块之间实现电路连通，因此第一导电块与第二导电块可以共用终端的供电模组，比如，第一导电块从终端的供电模组获取电能后，第二导电块可以直接从第一导电块获取电能，而无需再连接与终端的供电模组的电路，从而减少电路的布设空间。
与现有技术不同的是，将导电层分为不同导电块，其中，各个导电块之间的模式可以为自容式，也可以为互容式，终端可以识别出作用于盖板上的压力的位置点所对应的在导电块的位置点。
所述第一导电块5041和所述第二导电块5042分别贴合于所述中框503的上表面53；
所述第一导电块5041与所述显示模组502的下表面52之间存在第一间隙(如图16中第一导电块与显示模组的下表面之间的间隙)，其中，所述第一导电块5041、所述显示模组502的下表面52和所述第一间隙形成第一电容器，即：第一导电块看做第一电容器的一个极板，显示模组的下表面看做第一电容器的另一个极板；所述第二导电块5042与所述显示模组502的下表面之间存在第二间隙(如图16中第二导电块与显示模组的下表面之间的间隙)，其中，所述第二导电块5042、所述显示模组502的下表面52和所述第二间隙形成第二电容器，即：第二导电块看做第二电容器的一个极板，显示模组的下表面看做第二电容器的另一个极板，其中，所述第一电容器和所述第二电容器 的电容变化反应出作用于所述盖板501上的第一压力的大小。
本发明实施例中，第一导电块，显示模组的下表面以及第一间隙形成第一电容器，第二导电块，显示模组的下表面以及第二间隙形成第二电容器，由于第一导电块与第二导电块连接，因此，第一电容器和第二电容器的电容变化反应出作用于盖板上的第一压力的大小，比如：单指按压触摸屏盖板时，单指施加的压力可导致第一电容器和第二电容器的电容发生变化，从而第一电容器和第二电容器的电容变化可以反应出作用于触摸屏盖板上的单指按压的压力的大小。
在图15所示实施例的基础上，请参阅图17，为终端1700的一个结构示意图，其中，所述导电层504至少包括第三导电块5043和第四导电块5044；所述第三导电块5043与所述第四导电块5044不连接；
与现有技术不同的是，将导电层分为不同导电块，其中，各个导电块之间的模式可以为自容式，也可以为互容式，终端可以识别出作用于盖板上的压力的位置点所对应的在导电块的位置点。另外，作用在盖板上的力引起整个导电层的变形，而导电层在各个位置点的变形程度也不相同，因此，可感应出不同电容器的电容的变化。
需要说明的是，导电层的材质为ITO膜或FPC，当然，也可以是其他具有导电性的材质，此处不做具体限定。
所述第三导电块5043和所述第四导电块5044分别贴合于所述中框503的上表面53；
所述第三导电块5043与所述显示模组502的下表面52之间存在第三间隙(如图17中第三导电块与显示模组的下表面之间的间隙)，其中，所述第三导电块5043、所述显示模组502的下表面52和所述第三间隙形成第三电容器，即：第三导电块看做第三电容器的一个极板，显示模组的下表面看做第三电容器的另一个极板，其中，所述第三电容器的电容变化反应出作用于所述盖板501上的第二压力的大小；
所述第四导电块5044与所述显示模组502的下表面52之间存在第四间隙(如图17中第一导电块与显示模组的下表面之间的间隙)，其中，所述第四导电块5044、所述显示模组502的下表面和所述第四间隙形成第四电容器， 即：第四导电块看做第四电容器的一个极板，显示模组的下表面看做第四电容器的另一个极板，其中，所述第四电容器的电容变化反应出作用于所述盖板501上的第三压力的大小。
本发明实施例中，第三导电块，显示模组的下表面以及第三间隙形成第三电容器，第四导电块，显示模组的下表面以及第四间隙形成第四电容器，由于第三导电块与第四导电块不连接，因此，第三电容器的电容变化反应出作用于盖板上的第二压力的大小，第四电容器的电容变化反应出作用于盖板上的第三压力的大小，比如：双指按压触摸屏盖板时，双指中的第一指作用于第一导电块对应的盖板的第一区域，双指中的第二指作用于第二导电块对应的盖板的第二区域，第一指产生的压力使得第三电容器的电容发生变化，第二指产生的压力使得第四电容器的电容发生变化，从而第三电容器的电容变化可以反应出作用于触摸屏盖板上的双指中其中一个手指按压的压力的大小，第四电容器的电容变化可以反应出作用于触摸屏盖板上的双指中另一个手指按压的压力的大小。可见，将第一导电块与第二导电块不连接，可以实现多指触控，有效提高了用户体验。
