为了保持本公开实施例的以下说明清楚且简明，本公开省略了已知功能和已知部件的详细说明。
本公开至少一个实施例提供一种压力触控检测方法、触控面板及电子装置。本公开至少一个实施例将压力触控集成在触摸面板之中，利用不同压力触摸操作时触摸面积发生改变的现象，通过触摸面积的大小来表征触控压力的大小，以实现压力触控检测，从而无需额外增加压力传感器，简化压力触控面板的制备工艺、提高产品良率、降低压力触控技术的生产成本，实现电子装置的轻薄化。
需要说明的是，在本公开下面对实施例的描述中，以第一触控压力小于第二触控压力为例进行说明。
图1a-1b示出了当使用手指进行触摸时其触控压力与触摸面积的关系示意图。
当用户的手指最开始与触摸屏形成接触时，手指与触摸屏之间的触摸面积最小，随着手指继续施加压力，手指与触摸屏的触摸面积则持续增大。手指施加到触摸屏上的触摸压力不同，手指与触摸屏之间的触摸面积也不同。如图1a所示，在第一触控压力下，手指11与触摸屏10之间形成第一触摸面积12；如图1b所示，在第二触控压力下，手指11与触摸屏10之间形成第二触摸面积13，且第一触摸面积12小于第二触摸面积13。触摸面积的大小与触摸压力的大小正相关，触摸压力较大时，触摸面积也较大，从而可以利用触摸面积的大小表征触摸压力的大小，通过检测触摸面积，产生对应的触摸压力信号，该触摸压力信号可以提供给例如操作***以执行相应的压力触控操作，实现压力触控技术。
图2a示出了本公开一实施例提供的一种压力触控检测方法的示意性流程图，图2b示出了图2a中步骤S02的示意性流程图。
如图2a所示，本公开实施例提供的压力触控检测方法可以包括：
步骤S01：提供触控检测单元阵列。
步骤S02：检测触控检测单元阵列被触摸时的触摸面积，根据触摸面积输 出不同的触控压力信号。
步骤S03：根据触控压力信号执行相应的操作。
本公开实施例提供的压力触控检测方法，利用触控面板被例如手指触摸时的触摸面积的大小来表征触控压力的大小，产生不同的触控压力信号，从而执行不同的触控功能。由此，无需额外增加压力传感器，简化压力触控面板的制备工艺，提高产品良率，降低压力触控面板的生产成本，实现电子装置的轻薄化。
例如，触控检测单元阵列包括多行多列的多个触控检测单元，触控检测单元彼此相邻布置；根据该触控面板的分辨率，触控检测单元每个可占据较小的一定面积，多个触控检测单元一起占据较大的一定面积。例如，触摸面积可以由被触摸的触控检测单元的个数表征。或者，当触控检测单元为电容触控检测单元时，触摸面积可以由被触摸的触控检测单元产生的电容的大小表征。例如，一个触控检测单元被全部触摸时产生的电容大于被部分触摸时产生的电容；又例如，一个触控检测单元被触摸时，第一触控压力下产生的电容小于第二触控压力下产生的电容，电容的大小与触控压力的大小成正比。触控检测单元阵列可以有多种实现方式，本公开的实施例不限于这些具体的实现方式。例如，该触控检测单元阵列可以为互电容触控检测单元阵列或自电容触控检测单元阵列，相应地，触控检测单元可以为自电容触控检测单元或互电容触控检测单元。
例如，触控压力可以按压力值大小划分为多个不同的等级，每个触控压力的等级对应一个或多个压力取值范围。例如，触控压力可以划分为轻点、轻按、重按等多个等级，轻点、轻按、重按所对应的压力值依次增大。例如，轻点对应的压力值范围为(a，b)，轻按对应的压力值范围为(c，d)，重按对应的压力值为(e，f)，则a<b<c<d<e<f，且a、b、c、d、e、f均大于零。
例如，根据不同的触控压力的等级，可以由用户自主设置不同或相同的操作指令，也可以由***自动设置不同或相同的操作指令，从而完成相应的压力触控操作。
例如，若压力触控的操作对象是视频播放类应用程序，可以预设以下压力操作指令：轻点，执行视频播放/暂停操作；轻按，执行视频快进操作；重按，执行视频快退操作。例如，若接收到触控压力的等级为轻点的触控压力信号，则执行触控压力的等级为轻点时对应的操作指令，即在视频处于播放状态时，暂停播放视频，在视频处于暂停状态时，继续播放视频。又例如，在编辑文本时，轻按用于移动光标的操作，而重按用于选择文字以便进行复制、删除等操 作。
例如，触摸面积的大小与触控压力的大小正相关，即触控压力越大，则触摸面积越大，相应的触控检测单元阵列被触摸的触控检测单元的数量更多，根据触控检测单元阵列被触摸时的触摸面积大小，就可以确定对应的触控压力的等级，执行相应的触控操作。例如，压力触控的操作对象是视频播放类应用程序，预设以下触摸面积范围及压力操作指令：轻点对应的触摸面积的范围为(0，A)，执行视频播放/暂停操作；轻按对应的触摸面积的范围为(A，B)，执行视频快进操作；重按对应的触摸面积的范围为(B，C)，执行视频快退操作。当触控检测单元阵列检测到触摸操作，且触摸面积小于A，则输出对应触控压力的等级为轻点的触控压力信号，执行视频播放/暂停操作；若触摸面积大于A且小于B，则输出对应触控压力的等级为轻按的触控压力信号，执行视频快进操作；若触摸面积大于B且小于C，则输出对应触控压力的等级为重按的触控压力信号，执行视频快退操作。
需要说明的是，以上说明中对触控压力的划分是示意性说明，触控压力的大小并不局限于轻点、轻按、重按三种划分，例如还可以继续细化触控压力。例如，触控压力还可以继续划分为轻度轻按、中度轻按或重度轻按等，轻度轻按、中度轻按或重度轻按所对应的触控压力值依次增大，相应的触摸面积也依次增大。
例如，触控检测单元可以为电容触控检测单元。电容触控检测单元被触摸时可产生触控电容数据，触摸面积可以由触控电容数据的三维波形的特征参数表示。如图2b所示，步骤S02的一个示例可以包括：
步骤S021：获取触控检测单元阵列被触摸时的触控电容数据的三维波形。
步骤S022：确定三维波形的特征参数，触摸面积由特征参数表示。
步骤S023：判断触摸面积的大小，输出相应的触控压力信号。
例如，在步骤S023中，在触摸面积较大时输出表示触控压力较大的信号，而在触摸面积较小时输出表示触控压力较小的信号。
需要说明的是，对于例如第一触控压力和第二触控压力而言，第一触控压力形成的触摸面积较小，第二触控压力形成的触摸面积较大。也就是说，第一触控压力形成的触摸面积小于第二触控压力形成的触摸面积。
图3a示出了一种触控电容数据的三维波形示意图。
例如，触控检测单元阵列包括布置为多行多列的多个触控检测单元，该触控检测单元为电容触控检测单元，当产生触摸操作时，如图3a所示，手指与 触摸屏产生接触，该电容触控检测单元中被触摸位置的电容值会发生变化，从而在虚拟空间中可以形成对应于被施加压力的突起的三维波形。根据触控压力的不同，每个电容触控检测单元的电容值的变化量也不同，形成的三维波形也不同，从而可以利用该三维波形的至少一个特征参数表示触控压力的大小。例如，该三维波形可以具有波峰形状，其中心位置(最高位置)对应于被触摸位置的中心位置。
例如，图3b-3c示出了本公开一实施例提供的一种三维波形的特征参数示意图，图3d为沿图3c中线A-A'方向的该三维波形的水平截面示意图。
例如，在步骤S022中，该三维波形的特征参数可以包括垂直截面参数和水平截面参数。如图3b-3c所示，垂直截面参数包括但不限于波形半高宽220(221)、波形峰值210(211)、波形宽度230(231)、波形面积240(241)或波形积分(图中未示出)等。如图3d所示，水平截面参数可以包括波形水平截面面积250(251)，例如，可以为半波高度的波形水平截面面积。触摸面积由三维波形的波形半高宽220(221)、波形峰值210(211)、波形宽度230(231)、波形面积240(241)和波形水平截面面积250(251)中的至少一个表示。
例如，在第一触控压力下，波形半高宽220、波形水平截面面积250、波形峰值210、波形宽度230和波形面积240小于第二触控压力下相应的波形半高宽221、波形水平截面面积251、波形峰值211、波形宽度231和波形面积241。触摸面积可以由三维波形的上述任一特征参数表示，也可以由三维波形的上述多个特征参数综合表示，从而获得更准确的触摸面积与触控压力之间的对应关系。例如，可以综合波形半高宽和波形水平截面面积的数据表示触摸面积。在一个示例中，在第一触控压力下，三维波形具有第一波形水平截面面积250和第一波形半高宽220；在第二触控压力下，三维波形具有第二波形水平截面面积251和第二波形半高宽221。那么，当第一波形水平截面面积250小于第二波形水平截面面积251，且第一波形半高宽220小于第二波形半高宽221时，则表示第一触控压力形成的触摸面积小于第二触控压力形成的触摸面积。但不限于此，还可以对水平截面面积和波形半高宽分别设置权重，并根据水平截面面积和波形半高宽的加权和判断触摸面积的大小。
例如，该三维波形的特征参数可以通过迭代算法、统计直方图分析法、傅里叶变换方法或非线性最小二乘法等各种方法计算得到。
需要说明的是，触摸面积变化的原因包括压力触控、多指触控或手掌触控等情况，因此在本公开的实施例中，为了实现压力触控的检测与操作需要排除 上述多指触控或手掌触控等情况。本公开实施例的压力触控检测方法中，如图2b所示，步骤S021的一个示例还可以包括检测三维波形是否为连续波形和三维波形的坐标是否发生明显的移动。当三维波形为连续波形且三维波形的坐标没有发生明显的移动时，进行到步骤S022；当三维波形不是连续波形和/或三维波形的坐标发生明显的移动时，执行对应的其他功能，例如，当利用两指进行触控操作以实现多点触控时，触控电容数据具有分开的两个三维波形，当该两个三维波形彼此相对远离移动时，可以执行画面放大操作，而当两个波形彼此相对靠近移动时，可以执行画面缩小操作；当三维波形不是连续波形和/或三维波形的坐标发生明显的移动，且该三维波形没有对应的操作指令时，不执行任何操作或输出错误操作指令。
需要说明的是，当前触摸操作的类型可以根据触控压力的等级进行划分，例如，当前触摸操作的类型可以包括轻点触摸操作、轻按触摸操作和重按触摸操作等，其分别对应触控压力为轻点、轻按或重按，但不限于此。
本公开至少一实施例提供的一种压力触控检测方法，包括例如将对触控操作设备(例如移动电话、平板电脑、笔记本电脑等)进行首次触摸操作时检测到的触摸面积存储为触摸特征数据(例如，存储为对应于轻按的数据)，在之后的触摸操作中检测当前触摸操作的触摸面积并将其与触摸特征数据进行比较，根据比较结果确定当前触摸操作的类型，输出与当前触摸操作的类型对应的触控压力信号，执行相应的操作。又或者，当触控操作设备的压力触控功能被投入使用时，可以进行触摸特征数据的录入程序，例如可以分别录入对应于不同压力等级的触摸特征数据。例如，对应于轻按的第一触摸特征数据、对应于重按的第二触摸特征数据等，这些触摸特征数据将在之后触控操作设备的使用中被用于压力触控检测。
例如，本公开一实施例提供的一种压力触控检测方法可以适用于公共设备，也可以适用于个人设备。
图4a-4b示出了本公开一实施例提供的一种压力触控检测方法的示意性流程图。以下，参考图4a和4b详细描述本公开一实施例提供的压力触控检测方法。
如图4b所示，本公开一实施例提供的一种压力触控检测方法，在触控操作设备存储有对应于轻点阈值的第一触摸特征数据以及对应于轻按阈值的第二触摸特征数据的情况下，包括：
步骤S11：提供触控检测单元阵列。
步骤S13：检测当前触摸操作的触摸面积。
步骤S14：判断当前触摸操作的触摸面积是否大于第一触摸特征数据。
若当前触摸操作的触摸面积不大于第一触摸特征数据，进行到步骤S16，输出表示轻点的触控压力信号；然后进行到步骤S160，执行轻点对应的操作。
若当前触摸操作的触摸面积大于第一触摸特征数据，进行到步骤S15，判断当前触摸操作的触摸面积是否超过第二触摸特征数据。
若当前触摸操作的触摸面积不大于第二触摸特征数据，进行到步骤S17，输出表示轻按的触控压力信号；然后进行到步骤S170，执行轻按对应的操作。若当前触摸操作的触摸面积大于第二触摸特征数据，进行到步骤S18，输出表示重按的触控压力信号；然后进行到步骤S180，执行重按对应的操作。
例如，第一触摸特征数据、第二触摸特征数据和当前触摸操作的触摸面积可以由三维波形的相同特征参数表征。例如，第一触摸特征数据、第二触摸特征数据可以由波形半高宽220(221)表征，相应的当前触摸操作的触摸面积也可以由波形半高宽220(221)表征；或者，第一触摸特征数据、第二触摸特征数据也可以由波形水平截面面积250(251)表征，相应的当前触摸操作的触摸面积也可以由波形水平截面面积250(251)表征。
例如，可以在公共设备或个人设备的存储装置中预先存储第一触摸特征数据、第二触摸特征数据和不同触控压力等级的操作指令。例如，根据统计取样触控压力等级为轻点时对应的轻点触摸面积阈值，取该轻点触摸面积阈值的统计平均值作为第一触摸特征数据；根据统计取样触控压力等级为轻按时对应的轻按触摸面积阈值，取该轻按触摸面积阈值的统计平均值作为第二触摸特征数据。例如，当压力触控的操作对象是视频播放类应用程序，可以预先设置：压力触控的等级为轻点时，执行视频播放/暂停操作；压力触控的等级为轻按时，执行视频快进操作；压力触控的等级为重按时，执行视频快退操作。因此，若当前触摸操作的触摸面积小于第一触摸特征数据时，输出表示触控压力等级为轻点的触控压力信号，执行视频播放/暂停的操作；若当前触摸操作的触摸面积大于第一触摸特征数据且小于第二触摸特征数据时，输出表示触控压力等级为轻按的触控压力信号，执行视频快进的操作；若当前触摸操作的触摸面积大于第二触摸特征数据时，输出表示触控压力等级为重按的触控压力信号，执行视频快退的操作。
需要说明的是，根据压力触控检测方法的一个示例，在步骤S14之前，还可以包括检测三维波形是否为连续波形和三维波形的坐标是否发生明显的移 动。当三维波形为连续波形且三维波形的坐标没有发生明显的移动时，则进行到步骤S14；当三维波形不是连续波形和/或三维波形的坐标发生明显的移动时，执行对应的其他功能，例如，当利用两指进行触控操作以实现多点触控时，触控电容数据具有分开的两个三维波形，当该两个三维波形彼此相对远离移动时，可以执行画面放大操作，而当两个三维波形彼此相对靠近移动时，可以执行画面缩小操作；当三维波形不是连续波形和/或三维波形的坐标发生明显的移动且该三维波形没有对应的操作指令时，则不执行任何操作或输出错误操作指令。
如图4a所示，在步骤S13之前，本公开一实施例提供的压力触控检测方法还可以包括：
步骤S12：检测首次触摸操作的触摸面积。
步骤S120：存储首次触摸操作的触摸面积为第一触摸特征数据。
例如，第一触摸特征数据可以存储在公共设备或个人设备的存储装置中。
例如，第一触摸特征数据为公共设备或个人设备首次触摸操作的初始压力值对应的触摸面积。例如，可以在***中预先设置第二触摸特征数据与第一触摸特征数据的对应关系，当得到第一触摸特征数据时，可以通过简单的计算得到第二触摸特征数据。例如，在***中预先设置第二触摸特征数据为第一触摸特征数据的1.5倍，得到第一触摸特征数据之后，乘以系数1.5就可以得到第二触摸特征数据，第二触摸特征数据也可以存储在公共设备或个人设备的存储装置中。
例如，首次触摸操作的触摸面积可以设置为对应触控压力等级为轻点，也可以设置为对应触控压力等级为轻按或重按，然后通过三维波形的变化判断其余的触控压力等级。
例如，可以将公共设备使用时首次触摸操作的压力值视为轻点，保存相应的触摸面积为第一触摸特征数据；若压力增加，则触摸面积增大，当触摸面积大于第一触摸特征数据的1.1倍时，视为轻按；若压力继续增大，则触摸面积也继续增大，当触摸面积大于第一触摸特征数据的1.3倍时，视为重按。
本公开另一实施例提供的一种压力触控检测方法，包括录入用户对触控操作设备(例如移动电话、平板电脑、笔记本电脑等)进行轻点、轻按、重按操作时的触摸面积，并将其存储以作为触摸特征数据，在之后的触摸操作中检测当前触摸操作的触摸面积并将其与触摸特征数据进行比较，根据比较结果确定当前触摸操作的类型，输出与当前触摸操作的类型对应的触控压力的信号，执 行相应的操作。
例如，本公开另一实施例提供的一种压力触控检测方法可以适用于个人设备，也可以适用于公共设备。
图5a-5b示出了本公开另一实施例提供的一种压力触控检测方法的示意性流程图。以下，参考图5a和5b详细描述本公开另一实施例提供的压力触控检测方法。
如图5b所示，本公开另一实施例提供的一种压力触控检测方法，在存储有对应于轻点阈值的第三触摸特征数据以及对应于轻按阈值的第四触摸特征数据的情况下，包括：
步骤S21：提供触控检测单元阵列。
步骤S23：检测当前触摸操作的触摸面积。
步骤S24：判断当前触摸操作的触摸面积是否大于第三触摸特征数据。
若当前触摸操作的触摸面积不大于第三触摸特征数据，进行到步骤S26，即输出表示轻点的触控压力信号；然后进行到步骤S260，执行轻点对应的操作。
若当前触摸操作的触摸面积大于第三触摸特征数据，进行到步骤S25，判断当前触摸操作的触摸面积是否大于第四触摸特征数据。
若当前触摸操作的触摸面积不大于第四触摸特征数据，进行到步骤S27，输出表示轻按的触控压力信号；然后进行到步骤S270，执行轻按对应的操作；若当前触摸操作的触摸面积大于第四触摸特征数据，进行到步骤S28，输出表示重按的触控压力信号；然后进行到步骤S280，执行重按对应的操作。
例如，第三触摸特征数据、第四触摸特征数据和当前触摸操作的触摸面积可以由三维波形的相同特征参数表征。例如，第三触摸特征数据、第四触摸特征数据可以由波形半高宽220(221)表征，相应的当前触摸操作的触摸面积也可以由波形半高宽220(221)表征；或者，第三触摸特征数据、第四触摸特征数据也可以由波形水平截面面积250(251)表征，相应的当前触摸操作的触摸面积也可以由波形水平截面面积250(251)表征。
例如，可以在公共设备或个人设备的存储装置中预先存储第三触摸特征数据、第四触摸特征数据和不同等级的压力触控操作指令。例如，根据统计取样触控压力等级为轻点时对应的轻点触摸面积阈值，取该轻点触摸面积阈值的统计平均值作为第三触摸特征数据；根据统计取样触控压力等级为轻按时对应的轻按触摸面积阈值，取该轻按触摸面积阈值的统计平均值作为第四触摸特征数据。例如，当压力触控的操作对象是视频播放类应用程序，可以预先设置：压 力触控的等级为轻点时，执行视频播放/暂停操作；压力触控的等级为轻按时，执行视频快进操作；压力触控的等级为重按时，执行视频快退操作。因此，若当前触摸操作的触摸面积小于第三触摸特征数据时，输出表示触控压力等级为轻点的触控压力信号，执行视频播放/暂停的操作；若当前触摸操作的触摸面积大于第三触摸特征数据且小于第四触摸特征数据时，输出表示触控压力等级为轻按的触控压力信号，执行视频快进的操作；若当前触摸操作的触摸面积大于第四触摸特征数据时，输出表示触控压力等级为重按的触控压力信号，执行视频快退的操作。
如图5a所示，在步骤S23之前，本公开另一实施例提供的压力触控检测方法还可以包括：
步骤S22：检测用户轻点操作时的触摸面积阈值和用户轻按操作时的触摸面积阈值。
步骤S220：存储轻点操作时的触摸面积阈值为第三触摸特征数据，存储轻按操作时的触摸面积阈值为第四触摸特征数据。
例如，第三触摸特征数据和第四触摸特征数据可以存储在公共设备或个人设备的存储装置中。
例如，当压力触控检测方法用于公共设备时，第三触摸特征数据和第四触摸特征数据可以由公共设备***预先设定；也可以在公共设备使用时将单次触摸操作对应的触摸面积值设定为第三触摸特征数据和第四触摸特征数据。当压力触控检测方法用于个人设备时，第三触摸特征数据和第四触摸特征数据可以由个人设备***预先设定；也可以由用户根据实际需要实时进行个性化设置；还可以由个人设备对用户的操作习惯进行统计，并根据统计结果自动进行触摸面积的划分，分别对应不同的压力触控等级，从而对应不同的预设压力操作指令，最大限度地适应用户的实际操作需求。例如，当个人设备初次使用时，对用户轻点、轻按、重按等用力习惯进行检测并保存相应的触摸面积作为预设触控压力等级。
需要说明的是，在步骤S24之前，本公开实施例的方法还可以包括检测三维波形是否为连续波形和三维波形的坐标是否发生明显的移动，对应的步骤可以参考上述实施例中的相关描述，在此不再赘述。
例如，根据触控压力的等级，触摸特征数据可以包括多个，以对应多个不同等级的触控压力。例如，当触控压力继续被划分为轻度轻按、中度轻按和重度轻按时，还可以设置第五触摸特征数据、第六触摸特征数据、第七触摸特征 数据以分别存储轻度轻按操作时的触摸面积阈值、中度轻按操作时的触摸面积阈值和重度轻按操作时的触摸面积阈值。本公开的实施例对此不作限制。
