触觉反馈基板通常需要能够实现多种不同的振型，以提供不同的触觉体验。不同的振型对触觉反馈基板上的电极的宽度的要求不同。在相关技术中，触觉反馈基板通常将其中一种振型作为基础振型，并根据基础振型的最优方式来设置电极。触觉反馈基板利用其所设置的电极，来实现基础振型以外的其他振型。然而，触觉反馈基板上所设置的电极与其他振型对电极的要求并不匹配，这会导致触觉反馈基板在实现其他振型时振动幅度很小。这降低了触觉体验的丰富程度，制约了用户的触觉体验。
本公开可以提供一种觉反馈装置及其驱动方法。参见图1，触觉反馈装置包括相互配合的触觉反馈基板PNL和控制器CTR。
在本公开中，参见图4～图6，所述触觉反馈基板PNL包括依次层叠设置的衬底基板BP、第一电极层EP1、压电层PE和第二电极层EP2；所 述第一电极层EP1和所述第二电极层EP2的相互交叠的部分形成多个沿行方向H1依次排列的电极对EE。当在第一电极层EP1和第二电极层EP2之间加载交流电压时，压电层PE将会产生周期性形变，进而向衬底基板BP传递振动。
在本公开中，所述控制器CTR被配置为，能够在多种驱动模式中确定一种所述驱动模式作为目标驱动模式；其中，在任意一种所述驱动模式中，参见图3和图7～图9，所述电极对EE组合出沿所述行方向H1依次相邻的多个驱动单元DE，每个所述驱动单元DE包括依次相邻且数量相同的所述电极对EE；在不同的所述驱动模式下，所述驱动单元DE中的所述电极对EE的数量不同；
所述控制器CTR还被配置为，驱动所述目标驱动模式的一个或者多个所述驱动单元DE。这样，被驱动的驱动单元DE中的各个电极对EE可以被控制器CTR驱动，以使得压电层PE响应电极对EE之间的电场而带动触觉反馈基板PNL振动，进而形成触觉。
本公开提供的触觉反馈装置能够根据触觉反馈基板PNL所需实现的振型来确定目标驱动模式；在目标驱动模式下，控制器CTR可以将一个驱动单元DE作为整体进行驱动，使得驱动单元DE的宽度与触觉反馈基板PNL的振型相匹配，进而使得触觉反馈基板PNL在该振型下获得最大振幅。参见图7～图9，当触觉反馈基板PNL所需实现的振型改变时，控制器CTR可以改变驱动模式，进而改变被驱动的驱动单元DE，使得改变后的驱动单元DE的宽度与改变后的振型相匹配。这样，本公开的触觉反馈装置可以根据触觉反馈基板PNL所需实现的振型来改变驱动单元DE的宽度，进而能够使得触觉反馈基板PNL在不同的振型下的振幅得到提升，可以提高振幅的调整范围，使得触觉感受更为细腻。
下面，结合附图对本公开提供的触觉反馈装置的结构、原理和效果做进一步地解释和说明。
在本公开的实施方式中，参见图2，触觉反馈基板PNL可以设置有多个电极对EE，电极对EE可以沿列方向H2延伸以在整体上呈条形分布。各个电极对EE可以沿行方向H1依次排列。在本公开的一种实施方式中，各个电极对EE可以沿行方向H1等间隔依次排列。
在本公开中，行方向H1和列方向H2为平行于触觉反馈基板PNL平面且相互垂直的两个方向。在本公开的一种实施方式中，衬底基板BP可以呈矩形，则行方向H1和列方向H2中的一个平行于衬底基板BP的长边方向，另一个平行于衬底基板BP的短边方向。举例而言，行方向H1平行于衬底基板BP的长边方向，列方向H2平行于衬底基板BP的短边方向。
在本公开的一种实施方式中，触觉反馈基板PNL还设置有绑定焊盘和驱动走线，第一电极层和第二电极层中的电极通过驱动走线与绑定焊盘连接，绑定焊盘用于与控制器电连接。这样，控制器与第一电极层和第二电极层中的电极电连接，以便向各个电极组EE加载驱动信号。
在本公开中，触觉反馈基板PNL被设计为用于实现多种不同的振型，例如实现多种预先设定的振型或者实现一个振型范围内的各个振型。可以将触觉反馈基板PNL所能够实现的各个振型定义为该触觉反馈基板PNL的振型集合。在每次驱动触觉反馈基板PNL时，将触觉反馈基板PNL将要达成的振型定义为目标振型。可以理解的是，每一种振型对电极的宽度的要求均不相同。在本公开中，可以将与一种振型最匹配的电极定义为该振型对应的参考电极。当触觉反馈基板PNL按照一种振型的参考电极来布设电极时，该触觉反馈基板PNL可以在该振型下实现最大振幅，进而使得该振型具有更优的触觉体验和更宽的触觉调节幅度。在本公开中，将与目标振型最匹配的参考电极，定义为目标参考电极。当触觉反馈基板PNL的电极为目标参考电极时，该触觉反馈基板PNL可以使得目标振型的振幅最大。
本公开的触觉反馈基板PNL可以具有多个参考频率和各个参考频率对应的参考尺寸。其中，参考频率为，能够使得压电层PE的振动频率为触觉反馈基板PNL的固有频率的电压的频率。当驱动电极对EE的驱动信号的频率为一个参考频率时，压电层PE的振动频率为触觉反馈基板PNL的一个固有频率(例如一阶固有频率)，这能够使得触觉反馈基板PNL在固有频率下振动而产生共振；该共振所传导的横波的波长的一半，为该参考频率对应的参考尺寸。换言之，参考尺寸为所述触觉反馈基板PNL在其某一个固有频率下振动时所传导的横波的波长的一半。
在本公开的一些实施方式中，触觉反馈基板PNL不同的振型可以与 不同的参考频率相对应，即一种振型表示触觉反馈基板PNL在一种参考频率下的振动。一种振型对应的参考电极的宽度，可以等于该振型对应的参考频率所对应的参考尺寸。
在本公开的一些实施方式中，控制器CTR可以为振型集合中的每一种振型提供对应的驱动模式。当控制器CTR按照一种驱动模式来驱动触觉反馈基板PNL时，该触觉反馈基板PNL可以实现该驱动模式对应的振型。在本公开中，可以将控制器CTR所能够提供的各个驱动模式，定义为该控制器CTR的驱动模式集合。
在本公开的一种实施方式中，控制器CTR可以从驱动模式集合中选择出与目标振型相对应的驱动模式，作为目标驱动模式。当控制器CTR按照目标驱动模式驱动触觉反馈基板PNL时，该触觉反馈基板PNL可以实现目标振型且实现振幅的最大化。
在本公开中，可以使得电极对EE具有较小的宽度(沿行方向上的尺寸)。这样，参见图3，可以将多个相邻的电极对EE组合成驱动单元DE，进而利用驱动单元DE模拟参考电极。图7～图9中，用虚线ZL示意了触觉反馈基板PNL在不同的振型下的表面形貌。参见图7～图9，在不同的振型下，触觉反馈基板PNL的振动形貌不同，其振动时的开口大小不同；相应的，不同的振型下对电极的宽度的要求不同。在本公开中，当触觉反馈基板PNL需要改变振型时，控制器CTR可以重新调整驱动单元DE中的电极对EE的数量，以使得驱动单元DE的宽度与触觉反馈基板PNL的振型相匹配，进而使得触觉反馈基板PNL在这些振型下均能够达到最大振幅。换言之，在不同的驱动模式下，驱动单元DE中的电极对EE的数量不同，这样可以使得不同驱动模式下的驱动单元DE所模拟的参考电极不同。当触觉反馈基板PNL的目标振型对应的参考电极的宽度较小时，则目标驱动模式中的驱动单元DE所包含的电极对EE的数量也较少；当触觉反馈基板PNL的目标振型对应的参考电极的宽度较大时，则目标驱动模式中的驱动单元DE所包含的电极对EE的数量也较多。
在本公开中，参见图11，电极对EE的宽度(行方向H1上的尺寸)为S1，相邻电极对EE之间的间距为S2，电极对EE的设置间距(Pitch)为P，则电极对EE的设置间距P＝电极对EE的宽度S1+相邻电极对EE之 间的间距S2。在本公开的一些实施方式中，可以使得驱动单元DE的宽度WD＝nP；其中，n为驱动单元DE中的电极对EE的数量，为正整数；P为电极对EE的设置间距。可以理解的是，在不同的驱动模式下，驱动单元DE中的电极对EE的数量不同(即n不同)。在一些实施方式中，电极对EE的设置间距可以较小，例如不大于2毫米，尤其是可以在0.5～1.5毫米之间。这样，可以使得电极对EE更灵活地组合出不同的驱动单元DE，进而使得PNL能够在更多的振型下获得最大振幅。可以理解的是，本公开的电极对EE的设置间距也可以在其他范围内，可以根据触控反馈基板PNL所需实现的振型进行选择和确认，以能够满足触控反馈基板PNL所需实现的各个振型为准。
在本公开的一种实施方式中，参见图7～图9，目标驱动模式的驱动单元DE的宽度，可以等于或者基本等于目标参考电极的宽度。换言之，为了使得触觉反馈基板PNL在目标振型的振幅最大，则触觉反馈基板PNL需要采用目标参考电极进行驱动；控制器CTR可以将与目标振型对应的驱动模式作为目标驱动模式，该目标驱动模式中的驱动单元DE为目标驱动单元，目标驱动单元的宽度等于目标参考电极的宽度。这样，目标驱动单元可以用于模拟目标参考电极，进而使得触觉反馈基板PNL可以实现目标振型的最大化。
触觉反馈基板PNL在工作时将会振动，振动使得阵列基板表面形成峰和谷，这些峰和谷可以作为触觉反馈基板的节点。其中，在一种驱动模式下，触觉反馈基板PNL所形成的节点的数量A是固定的，基本等于该驱动模式下所能够组合出的驱动单元的数量。其中，每个驱动单元所包括的电极对的数量越少，则该驱动单元的宽度越小，该驱动模式下触觉反馈基板PNL所能够形成的节点数量越多。在一些实施方式中，可以通过对触觉反馈基板PNL的长度L进行合理的调整，使得在各个驱动模式下，L基本等于驱动单元DE的宽度WD的整数倍。在本公开的一种实施方式中，L＝m*WD，m为正整数；在不同的驱动模式下，WD的大小不同，m的大小不同。在另外一些实施方式中，L＝m*WD+x，m为正整数，x为可调尺寸；其中，在不同的驱动模式下，WD的大小不同，m的大小不同，x可以相同也可以不相同。进一步地，在同一种驱动模式下，x大于0且不大 于WD的一半。
在本公开的一种实施方式中，在各个驱动模式下，驱动单元DE的宽度WD不大于15毫米。如此，触觉反馈基板PNL与用户手指之间能够有效地形成压膜效应，进而保证用户获得良好的触觉体验。在本公开的一种实施方式中，控制器CTR按照目标驱动模式进行驱动时，不仅可以使得目标驱动单元的宽度等于目标参考电极的宽度；而且可以使得加载至目标驱动单元上的驱动信号的频率，等于目标振型对应的参考频率，例如向驱动单元DE上的各个电极对EE加载频率为参考频率的交流信号。
举例而言，在本公开的一种实施方式中，触觉反馈基板PNL被设计为能够实现第一振型、第二振型和第三振型等三种不同的振型。其中，第一振型对应的参考电极的宽度为W1；第二振型对应的参考电极的宽度为W2；第三振型对应的参考电极的宽度为W3。则在触觉反馈基板PNL上，第一电极层EP1和第二电极层EP2形成沿行方向H1依次等间距排列的多个电极对EE，每个电极对EE的宽度为S1，相邻电极对EE之间的间距为S2；则电极对EE的设置间距P为S1+S2。
控制器CTR被配置为，从与第一振型对应的第一驱动模式、与第二振型对应的第二驱动模式和与第三振型对应的第三驱动模式中，选择一种驱动模式作为目标驱动模式。
在第一驱动模式中，驱动单元DE为第一驱动单元，第一驱动单元包括n1个依次相邻的电极对EE；则第一驱动单元DE的宽度WD1＝n1*P＝n1*(S1+S2)。n1为正整数。在第一驱动模式中，控制器CTR加载至驱动单元DE上的电压的频率，可以等于第一振型对应的参考频率。
在第二驱动模式中，驱动单元DE为第二驱动单元，第二驱动单元包括n2个依次相邻的电极对EE；则第二驱动单元DE的宽度WD2＝n2*P＝n2*(S1+S2)。n2为正整数。在第二驱动模式中，控制器CTR加载至驱动单元DE上的电压的频率，可以等于第二振型对应的参考频率。
在第三驱动模式中，驱动单元DE为第三驱动单元，第三驱动单元包括n3个依次相邻的电极对EE；则第二驱动单元DE的宽度WD3＝n3*P＝n3*(S1+S2)。n3为正整数。在第三驱动模式中，控制器CTR加载至驱动单元DE上的电压的频率，可以等于第三振型对应的参考频率。其中，n1、 n2和n3不相同。
可以理解的是，在本公开的其他实施方式中，触觉反馈基板PNL可以被设计为能够实现更多不同的振型，则控制器CTR可以相应的设置与各个振型相对应的驱动模式，以使得各个振型均能够达到最大振幅。
图10在触觉反馈基板PNL的众多电极对EE中，仅仅示出了相邻的12个，分别标记为电极对EE1～电极对EE12。如下，以该12个电极对EE在不同驱动模式下所归属的驱动单元为示例，对本公开的触觉反馈装置的结构和原理做进一步地解释和说明。
在该示例中，当触觉反馈基板PNL需要实现的目标振型的开口尺寸为2P(P＝S1+S2)时，则控制器CTR所确定的目标驱动模式中，每个驱动单元DE包含两个电极对EE。例如，电极对EE1和电极对EE2可以组成一个驱动单元DE，电极对EE3和电极对EE4可以组成一个驱动单元DE，以此类推，电极对EE11和电极对EE12可以组成一个驱动单元DE。
当触觉反馈基板PNL需要实现的目标振型的开口尺寸为3P(P＝S1+S2)时，则控制器CTR所确定的目标驱动模式中，每个驱动单元DE包含三个电极对EE。例如，电极对EE1、电极对EE2和电极对EE3可以组成一个驱动单元DE，电极对EE4、电极对EE5和电极对EE6可以组成一个驱动单元DE，电极对EE7、电极对EE8和电极对EE9可以组成一个驱动单元DE，电极对EE10、电极对EE11和电极对EE12可以组成一个驱动单元DE。
当触觉反馈基板PNL需要实现的目标振型的开口尺寸为4P(P＝S1+S2)时，则控制器CTR所确定的目标驱动模式中，每个驱动单元DE包含四个电极对EE。例如，电极对EE1、电极对EE2、电极对EE3和电极对EE4可以组成一个驱动单元DE，电极对EE5、电极对EE6、电极对EE7和电极对EE8可以组成一个驱动单元DE，电极对EE9、电极对EE10、电极对EE11和电极对EE12可以组成一个驱动单元DE。
在本公开的一种实施方式中，控制器CTR中可以预先设置有多个驱动模式，例如可以内置有驱动模式集合。控制器CTR可以接收来自外部电路(例如电子设备的微处理器)的模式选择信号，并根据该模式选择信号而从多个驱动模式中选择一个作为目标驱动模式。
在另外的一种实施方式中，控制器CTR可以预设有模式算法，其被配置为能够根据来自外部电路的模式选择信号确定振型信息，然后根据振型信息来计算出目标驱动模式。这样，该控制器CTR可以根据不同的振型信息来计算出不同的驱动模式，因此，其相当于根据振型信息在多种驱动模式中确定一种驱动模式作为目标驱动模式。
可选地，振型信息为与触觉反馈基板PNL所需实现的振型相关的信息，例如可以包括为了实现该振型所需的参考电极的宽度、为了实现该振型而所需的驱动信号频率等中的一种或者多种。当然的，在一些实施方式中，上述的参考电极的宽度、驱动信号频率等也可以被编码，并在控制器CTR中设置相应的映射表。在本公开中，这些能够使得控制器CTR直接或者间接获得目标振型所需的参考电极的宽度的信息，均为本公开中的振型信息。
在本公开中，参见图13，触觉反馈装置可以按照步骤S110～步骤S120所示的驱动方法来驱动：
步骤S110，从多种所述驱动模式中确定一种所述驱动模式作为目标驱动模式；
步骤S120，驱动所述目标驱动模式的一个或者多个所述驱动单元DE；其中，驱动任意一个所述驱动单元DE包括，向该驱动单元DE的各个所述电极组EE加载相同的驱动信号。
在本公开中，控制器CTR在驱动触觉反馈基板PNL时，可以驱动部分驱动单元DE，也可以驱动各个驱动单元DE。当相邻的两个驱动单元DE被驱动时，相邻的两个驱动单元DE上所加载的驱动信号可以不同，尤其是可以为反相的驱动信号。
举例而言，在本公开的一种实施方式中，步骤S120可以包括：向第偶数个所述驱动单元DE的各个所述电极组EE加载第一驱动信号；向第奇数个所述驱动单元DE的各个所述电极组EE加载第二驱动信号；所述第一驱动信号为所述第二驱动信号的反相信号。在该实施方式中，各个驱动单元DE均可以被驱动，以使得触觉反馈基板PNL的振型具有大的振幅。
再举例而言，在本公开的另一种实施方式中，步骤S120可以包括：
向第偶数个所述驱动单元DE的各个所述电极组EE加载所述驱动信 号，或者，向第奇数个所述驱动单元DE的各个所述电极组EE加载所述驱动信号。在该实施方式中，仅第偶数个驱动单元DE或者第奇数个驱动单元DE被驱动，即仅有一半的驱动单元被驱动。在本公开中，可以将这些被驱动的驱动单元DE定义为工作驱动单元；控制器CTR可以仅仅驱动工作驱动单元，而不驱动其他驱动单元。在本公开的其他实施方式中，除了通过驱动单元DE所处的奇数偶数位置外来确定工作驱动单元外，还可以通过其他方式来确定工作驱动单元，例如从每三个驱动单元DE中选择一个作为工作驱动单元，或者从每三个驱动单元DE中选择一个作为工作驱动单元，本公开对这些方式不做限定。
在一些实施方式中，参见图4和图5，第一电极层EP1和第二电极层EP2中的一个设置有沿行方向H1依次排列的多个条形电极EP0，另一个设置与各个所述条形电极EP0交叠的公共电极COM；任意一个所述条形电极EP0与所述公共电极COM组成一个所述电极对EE。
举例而言，参见图5，所述第一电极层EP1包括沿行方向H1依次排列的多个第一条形电极EP01(作为条形电极EP0)；第二电极层EP2设置有与各个第一条形电极EP01交叠的公共电极COM。则第一条形电极EP01与公共电极COM组成电极对EE。
再举例而言，参见图4，所述第二电极层EP2包括沿行方向H1依次排列的多个第二条形电极EP02(作为条形电极EP0)；第一电极层EP1设置有与各个第二条形电极EP02交叠的公共电极COM。则第二条形电极EP02与公共电极COM组成电极对EE。
在本公开的一种实施方式中，在驱动该触觉反馈基板PNL时，可以向第偶数个所述驱动单元DE的各个所述电极组EE加载所述驱动信号，或者，向第奇数个所述驱动单元DE的各个所述电极组EE加载所述驱动信号。驱动信号可以包括驱动电压信号和公共电压信号；可以向工作驱动单元的条形电极EP0加载驱动电压信号，且向公共电极COM加载公共电压信号。在本公开的一种实施方式中，驱动电压信号可以为交变电压信号、或者脉冲电压信号；公共电压信号为恒压信号。当然的，在本公开的其他实施方式中，驱动电压信号也可以为恒压信号，且公共电压信号可以为交变电压信号或者脉冲电压信号。
这样，在触觉反馈基板PNL设置有公共电极COM时，控制器CTR在驱动触觉反馈基板PNL时可以向公共电极COM加载公共电压信号，这使得各个电极对EE的公共电极COM的电压相同。因此，控制器CTR在各个驱动模式中，可以仅仅确定驱动单元DE中的各个电极对EE的条形电极EP0。换言之，在任意一种驱动模式中，控制器CTR可以根据各个条形电极EP0来确定该条形电极EP0所属的驱动单元DE，进而向该条形电极EP0加载相应的驱动电压信号。
在本公开的另外一种实施方式中，控制器CTR在驱动触觉反馈基板PNL时，可以同时驱动各个电极对EE，即采用两种不同的驱动信号来实现对各个电极对EE的驱动。控制器CTR可以向电极对EE加载三种不同的电压，即加载至公共电极COM的公共电压信号、加载至第偶数个驱动单元DE的各个条形电极EP0的第一驱动电压信号、加载至第奇数个驱动单元DE的各个条形电极EP0的第二驱动电压信号；其中，第一驱动电压信号和第二驱动电压信号可以为反相信号。这样，第偶数个驱动单元DE中，第一驱动电压信号和公共电压信号构成一组驱动信号；第奇数个驱动单元DE中，第二驱动电压信号和公共电压信号构成另一组驱动信号。进一步地，第一驱动电压信号和第二驱动电压信号可以为交变电压信号、或者脉冲电压信号；公共电压信号为恒压信号。
在本公开的一些实施方式中，所述第一电极层EP1包括沿行方向H1依次排列的多个第一条形电极EP01；所述第二电极层EP2包括沿行方向H1依次排列且与各个第一条形电极EP01一一对应的多个第二条形电极EP02；相对应的所述第一条形电极EP01和所述第二条形电极EP02相互交叠；所述第一条形电极EP01和对应的所述第二条形电极EP02组成所述电极对EE。换言之，本公开的电极对EE可以为电极对，电极对包括相互交叠的第一条形电极EP01和第二条形电极EP02。
在本公开的一种实施方式中，第一条形电极EP01和第二条形电极EP02在压电层PE的正投影完全重合。
在本公开的一种实施方式中，控制器CTR可以驱动各个驱动单元DE，并使得相邻两个驱动单元DE所形成的电场方向相反。例如，在步骤S120中，可以向第偶数个所述驱动单元DE中的各个所述第一条形电极EP01 加载第一驱动电压信号，向第偶数个所述驱动单元DE中的各个所述第二条形电极EP02加载第二驱动电压信号。向第奇数个所述驱动单元DE中的各个所述第一条形电极EP01加载所述第二驱动电压信号，向第奇数个所述驱动单元DE中的各个所述第二条形电极EP02加载所述第一驱动电压信号。这样，相邻两个驱动单元DE所加载的驱动信号保持相反。进一步地，第一驱动电压信号和第二驱动电压信号可以为交变电压信号、或者脉冲电压信号。
在本公开的另一种实施方式中，控制器CTR在驱动触觉反馈基板PNL时，还可以选择性地驱动部分驱动单元DE。作为一种示例，工作驱动单元可以为各个第偶数个驱动单元DE或者各个第奇数个驱动单元DE。换言之，控制器CTR在驱动触觉反馈基板PNL时，可以仅仅驱动第偶数个驱动单元DE或者第奇数个驱动单元DE。在驱动工作驱动单元时，可以向工作驱动单元的第一条形电极EP01加载第一驱动电压信号，向工作驱动单元的第二条形电极EP02加载第二驱动电压信号。
再举例而言，在本公开的一种实施方式中，在步骤S120中，向第偶数个所述驱动单元DE中的各个所述第一条形电极EP01加载第一驱动电压信号，向第偶数个所述驱动单元DE中的各个所述第二条形电极EP02加载第二驱动电压信号。或者，向第奇数个所述驱动单元DE中的各个所述第一条形电极EP01加载所述第二驱动电压信号，向第奇数个所述驱动单元DE中的各个所述第二条形电极EP02加载所述第一驱动电压信号。
在一些实施方式中，参见图12，条形电极EP0(例如第一条形电极EP01和/或第二条形电极EP02)可以被分为多个条形子电极EP0sub，各个条形子电极EP0sub均与控制器CTR各自独立地电连接。示例性地，参见图12，各个条形子电极EP0sub通过驱动走线LN与各自的绑定焊盘(图中未示出)电连接。
在正常情况下，在驱动条形电极EP0时，可以向条形电极EP0的各个条形子电极EP0sub加载相同的电压，以使得各个条形子电极EP0sub模拟条形电极EP0。当发现压电层PE存在缺陷时，例如压电层PE在某一特定位置存在短路缺陷时，则该特定位置处的条形子电极可以被控制器CTR所屏蔽；驱动器在驱动触觉反馈基板PNL时，不向该缺陷处的条形子电 极加载驱动信号。具体的，当任意一个条形子电极EP0sub所覆盖的压电层PE存在缺陷是，该条形子电极EP0sub可以被CRT所屏蔽；控制器CTR发送驱动信号时，不向该条形子电极EP0sub发送信号。
在一些实施方式中，衬底基板BP可以为无机材料的衬底基板，也可以为有机材料的衬底基板。举例而言，在本公开的一种实施方式中，衬底基板的材料可以为钠钙玻璃(soda-lime glass)、石英玻璃、蓝宝石玻璃等玻璃材料。在本公开的另一种实施方式中，衬底基板的材料可以为聚甲基丙烯酸甲酯(Polymethyl methacrylate，PMMA)、聚乙烯醇(Polyvinyl alcohol，PVA)、聚乙烯基苯酚(Polyvinyl phenol，PVP)、聚醚砜(Polyether sulfone，PES)、聚酰亚胺、聚酰胺、聚缩醛、聚碳酸酯(Poly carbonate，PC)、聚对苯二甲酸乙二酯(Polyethylene terephthalate，PET)、聚萘二甲酸乙二酯(Polyethylene naphthalate，PEN)或其组合。
当然的，在本公开的其他实施方式中，衬底基板也可以为具有特定功能的基板，例如可以为显示面板、触控面板、触控显示面板、彩膜基板、玻璃盖板等等。
在本公开的一些实施方式中，压电层PE的材料可以为无机压电材料、有机压电材料或者复合压电材料。在本公开的一种实施方式中，压电层PE的材料可以包括PZT(锆钛酸铅压电陶瓷)、PVDF(偏聚氟乙烯)、ZnO(氧化锌)等中的一种。
可选地，第一电极层EP1和第二电极层EP2材料可以选自导电材料，例如可以选择金属、导电性金属氧化物、导电性高分子、导电性复合材料或其组合。示例性的，金属可以选自铂、金、银、铝、铬、镍、铜、钼、钛、镁、钙、钡、钠、钯、铁、锰或其组合。示例性的，导电性金属氧化物可以选自氧化铟、氧化锡、铟锡氧化物、掺氟的氧化锡、掺铝的氧化锌、掺镓的氧化锌或其组合。示例性的，导电性高分子可以选自聚苯胺、聚吡咯、聚噻吩、聚乙炔、聚(3,4-伸乙基二氧噻吩)/聚苯乙烯磺酸(PEDOT/PSS)或其组合，导电性高分子中还可以添加有酸(例如盐酸、硫酸、磺酸等)、路易斯酸(例如氟化磷、氟化砷、氯化铁等)、卤素、碱金属等掺杂剂。示例性的，导电性复合材料可以选自分散有碳黑、石墨粉、金属微粒子等的导电性复合材料。在本公开的一种实施方式中，第一电极层EP1和第二 电极层EP2的材料可以包括Mo(钼)、Pt(铂)、ITO(氧化铟锡)中的一种。
可选地，控制器CTR可以与触觉反馈基板PNL绑定连接。在本公开的一种实施方式中，控制器CTR可以包括与触觉反馈基板PNL绑定的电路板和位于电路板上的驱动芯片，驱动芯片通过电路板驱动各个电极组EE。
本公开实施方式还提供一种电子设备，该电子设备包括上述触觉反馈装置实施方式所描述的任意一种触觉反馈装置。该电子设备可以为车载显示屏、手机屏幕或者其他类型的电子设备。由于该电子设备具有上述触觉反馈装置实施方式所描述的任意一种触觉反馈装置，因此具有相同的有益效果，本公开在此不再赘述。
