在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
参见图1，图1是本申请实施例提供的显示模组的结构示意图。如图1所示，本申请实施例提供的显示屏模组包括：显示屏10、压电传感器20、超声指纹模组30和控制模块，其中，所述压电传感器20和超声指纹模组30均设置在所述显示屏10的内侧，且所述压电传感器20和所述超声指纹模组30间隔设置；所述控制模块分别与所述压电传感器20和所述超声指纹模组30电连接；
其中，所述压电传感器20发射第一超声波信号，所述超声指纹模组30检测接收到的所述第一超声波信号的第一信号强度值，所述控制芯片基于第一信号强度值确定第一按压操作信息。
本申请实施例中，上述显示屏10可以理解为包括多层介质，例如可以包括显示层和玻璃层等。其中，所述压电传感器20和超声指纹模组30均设置在显示层的内侧。其中，压电传感器20和超声指纹模组30分别靠近显示屏10的两相对端设置，如图1所示，压电传感器20靠近显示屏10的左端设置，超声指纹模组30靠近显示屏10的右端设置。
需要说明的是，上述压电传感器20的数量可以根据实际需要进行设置，如图1所示，在一些实施例中，上述压电传感器20为一个，当然在一些实施例中，为了覆盖更多的检测区域，还可以设置两个压电传感器20，此时，两个压电传感器20分别设置在显示屏10的两相对端，超声指纹模组30可以设置在两个压电传感器20之间。
可选地，上述压电传感器20和超声指纹模组30可以粘接固定在显示屏10的内侧，如图2所示，在无手指按压显示屏时，压电传感器20发射的超声波的传输路径为路径1：经过粘胶剂到显示屏10内，再经过显示屏10和粘胶剂后传递到超声指纹模组30。此时由于显示屏10的外界都是空气，空气和显示屏之间的声阻抗差异过大，大部分能量都被返回。
如图3所示，当存在手指按压显示屏时，增加了传输路径2：经过粘胶剂到显示屏10内，再经过显示屏10传递到用户手指。此时部分能量折射到手指中，从而使得接收到第一超声波信号的能量减小。与此同时，有手指接触显示屏的界面时，整体的振动模态被改变，手指的接触相当于对整个系统起到了一种“减震”效果，使得超声传递的振动能量被削弱。因此，本申请实 施例中可以基于第一信号强度值检测按压情况，从而确定第一按压操作信息。
需要说明的是，上述超声指纹模组30可以包括呈阵列分布的多个压电单元，为了节省电量，可以通过设置超声指纹模组30中的第一压电单元检测接收到的所述第一超声波信号的第一信号强度值。该第一压电单元可以为超声指纹模组30中的一个压电单元或者由多个压电单元组成的集合。
可选地，可以选择一个压电单元作为第一压电单元，即最左侧中间的压电单元，也可以为最右侧中间的压电单元。如图1所示，假设选择接收单元(Receive 0，RX0)作为第一压电单元，当未存在手指按压屏幕时，第一压电单元接收到的波形如图4所示。如图5所示，当由手指按压时，由于部分超声波能量在手指出发生了折射，同时由于手指的接触导致整个系统的振动模态发生变化，发生了减震效果，此时第一压电单元接收的波形如图6所示。在图6中，实线表示手指未按压时第一压电单元接收到的波形，虚线表示手指未按压时第一压电单元接收到的波形。
应理解，超声波的能量传输路径主要分布在压电传感器20和第一压电单元之间的区间，但手指按压到屏幕的位置即使超出了压电传感器20和第一压电单元之间的区间也会对超声能量有一定的衰减，这主要是由于手指接触屏幕后对系统振动起到了减弱作用，所以有效按压识别区域会比压电传感器20和第一压电单元之间的区间更大，如图5的区域501所示。
本申请实施例中，通过设置显示屏模组包括：显示屏10、压电传感器20、超声指纹模组30和控制模块，其中，所述压电传感器20和超声指纹模组30均设置在所述显示屏10的内侧，且所述压电传感器20和所述超声指纹模组30间隔设置；所述控制模块分别与所述压电传感器20和所述超声指纹模组30电连接；其中，所述压电传感器20发射第一超声波信号，所述超声指纹模组30检测接收到的所述第一超声波信号的第一信号强度值，所述控制芯片基于第一信号强度值确定第一按压操作信息。这样通过压电传感器20和超声指纹模组30配合实现按压检测，从而无需在多个位置设置压电传感器20。因此，本申请实施例减小了显示屏模组中检测压力的元器件占用的空间。与此同时，相对于现有技术设置多个压力检测元件，本申请实施例仅需要增加一个压电传感器20，即可实现压力的检测，因此降低了成本。此外，还可以 避免压力传感器与超声指纹模组30设置位置的冲突。
可选地，在本申请实施例中，所述第一按压操作信息包括在第二方向的坐标信息和按压的压力值中的至少一项。
应理解，随着用户手指的按压力度增加，手指与显示屏10的接触面积增加，同时接触更加尽量，从而会导致更多的超声波能量被折射掉，因此可以根据接收到的能量的减弱程度确定用户手指按压的力度。假设用ΔS表示不同压力状态下超声波能量的衰弱程度，则ΔS与压力呈正相关关系，具体如图7所示。
可选地，如图8所示，在一些的实施例中，所述显示屏10包括沿第一方向依次排列的至少两个显示区域，所述超声指纹模组30检测包括与所述显示区域一一对应设置的第一压电单元，所述第一压电单元在所述显示屏的垂直投影位于对应的所述显示区域内，其中，所述第一压电单元检测接收到的所述第一超声波信号的第一信号强度值。
本申请实施例中，上述显示区域的数量为3个(显示区域A、显示区域B和显示区域C)，其中每一显示区域对应设有一个第一压电单元(RX0、RX1和RX2)。上述第一方向可以理解为纵向，即Y轴方向。当然在其他实施例中，第一方向可以为其他方向，例如斜向上的倾斜方向等，在此不做进一步的限定。由于将显示屏划分了多个显示区域，且每一显示区域内设置有用于检测接收到的所述第一超声波信号的第一信号强度值的第一压电单元，从而可以基于多个第一压电单元确定用户手指当前按压的显示区域，根据按压在不同的显示区域内，执行对应不同的按压操作。因此，本申请实施例可以提高操作控制的灵活性。
可选地，在一些实施例中，所述压电传感器20和所述超声指纹模组30沿第二方向间隔设置，所述第二方向垂直于所述第一方向。
本申请实施例中，上述第二方向可以理解为横向，即X轴向。压电传感器20和所述超声指纹模组30沿第二方向间隔设置可以理解为压电传感器20和所述超声指纹模组30间隔设置，且压电传感器20的几何中心和所述超声指纹模组30的几何中心的连线位于第二方向上。
可选地，在本申请实施例中，可以根据三个第一压电单元(RX0、RX1 和RX2)接收到的能量的差异，判断手指按压的区域，从而可以确定按压的纵向坐标信息，即第一方向的坐标信息。例如，假设某一显示区域对应的第一压电单元接收到的能量变化值大于其他各显示区域对应的第一压电单元接收到的能量的变化值，则可以确定该第一压电单元对应的显示区域为用户手指按压的区域。
假设三个第一压电单元检测到的超声波能量的衰弱程度ΔS如图9所示，其中S 0_A表示位于显示区域A对应的第一压电单元接收到压电传感器发射的超声波能量的衰弱程度，S 0_B表示位于显示区域A对应的第一压电单元接收到压电传感器发射的超声波能量的衰弱程度，S 0_C表示位于显示区域C对应的第一压电单元接收到压电传感器发射的超声波能量的衰弱程度。其中，由于S 0_B的值最大，表明用户手指当前按压的显示区域为显示区域B。
可选地，在一些实施例中，所述超声指纹模组30还包括与所述显示区域101一一对应的压电单元组，所述压电单元组在所述显示屏的垂直投影位于对应所述显示区域内，所述压电单元组包括第二压电单元和第三压电单元，所述第二压电单元位于所述第三压电单元与所述压电传感器之间，所述第三压电单元用于发射第二超声波信号，所述第二压电单元用于检测接收到的所述第二超声波的第二信号强度值，所述控制芯片还用于基于所述第一信号强度和所述第二信号强度确定第二按压操作信息。
本申请实施例中，上述第二压电单元和第三压电单元均可以为超声指纹模组30中的一个压电单元或者由多个压电单元组成的集合。其中，上述第二压电单元可以与第一压电单元为相同的压电单元，也可以为不同的压电单元。如图4所示，本申请实施例中，以上述第二压电单元与第一压电单元为相同的压电单元为例进行说明，在基于第一压电单元检测接收到的第一超声波信号的第一信号强度后，可以基于该第一信号强度确定用户手指按压的位置对应的显示区域，然后控制该显示区域对应的第三压电单元发射第二超声波信号，该显示区域对应的第一压电单元检测接收到的第二超声波信号的第二信号强度。此时，可以根据所述第二信号强度和所述第一信号强度确定第二按压操作信息，该第二按压操作信息可以包括在第二方向的坐标信息，即横向坐标信息。
需要说明的是，由于按压位置距离超声波发射端的距离不同，对超声波能量减弱的程度不同，因此，可以基于超声波能量减弱的程度确定横向的坐标信息。此外，为了避免按压压力对计算横坐标信息的影响，可以基于第一信号强度和第二信号强度的比值确定横坐标信息，以提高横坐标确定的准确性。
可选地，在一些实施例中，计算所述第二信号强度和所述第一信号强度的目标比值；基于预设的关联关系，确定所述目标比值对应的第二按压操作信息；其中，所述预设的关联关系用于表示所述第二信号强度和所述第一信号强度的比值信息与按压操作信息的关联关系，所述第二按压操作信息包括在第二方向的坐标信息。
本申请实施例中，可以将第二信号强度和第一信号强度的比值和横向的坐标位置做一个函数对应，形成上述关联关系。由于利用第二信号强度和所述第一信号强度的目标比值确定第二按压操作信息，从而可以使得超声指纹模组对应的区域作为按压检测区域，因此提高了按压检测区域的检测范围。当然在其他实施例中，还可以通过设置第一压电单元位于超声指纹模组30远离压电传感器的一侧，从而提高了按压检测区域的检测范围。
如图8所示，可以对应每一显示区域设置一个第三压电单元，其中显示区域A对应的第三压电单元为发送单元(Transmit 3，TX3)，显示区域B对应的第三压电单元为TX2，显示区域C对应的第三压电单元为TX1。本申请实施例还可以在第二方向将每一个显示区域划分为多个区域。在检测到用户按压的位置位于显示区域B的情况下，可以开启RX0对应的TX2，此时压电传感器20和TX2同时向RX0发送波形信号，当手指按压的位置在压电传感器20到RX0区间时，则S B_0大于S B_2，如图10所示。其中，S B_0表示RX0接收到电传感器20发射的超声波能量的衰弱程度，S B_2表示RX0接收到TX2发射的超声波能量的衰弱程度。
需要说明的是，在本申请实施例中，可以基于上述第一按压操作信息和第二按压操作信息执行相应的功能。例如可以根据坐标信息将显示屏划分为四个区域，其中，不同的区域对应不同的功能，且可以设置不同按压的压力值大小对应不同的功能。假设设置两个压力等级，则可以实现八种功能的按 压操作。
本申请实施例还提供一种电子设备，该电子设备包括上述实施例中的显示屏模组，该显示屏模组的结构可以参照上述实施例，在此不再赘述。由于本申请实施例提供的电子设备包括了上述实施例中的显示屏模组，因此本申请实施例提供的电子设备具有上述实施例中显示屏模组的全部有益效果。
参照图11，图11是本申请实施例提供的一种按压操作检测方法的流程图，如图11所示，包括以下步骤：
步骤1101，控制压电传感器发射第一超声波信号；
步骤1102，控制超声指纹模组检测接收到的所述第一超声波信号的第一信号强度；
步骤1103，根据所述第一信号强度确定第一按压操作信息。
本申请实施例中，上述第一按压操作信息包括在第一方向的坐标信息和按压的压力值中的至少一项。该第一方向可以为纵向。可选地，超声指纹模组和压电传感器的结构可以参照上述实施例。
在一些实施例中，可以通过超声指纹模组中的第一压电单元检测接收到的所述第一超声波信号的第一信号强度。若第一压电单元为一个，此时上述第一按压操作信息可以为按压的压力值。在另一实施例中，若上述第一压电单元为多个，且每一个对应一个基于第一方向划分的显示区域的情况下，第一按压操作信息包括在第一方向的坐标信息和按压的压力值中的至少一项。
本申请实施例通过控制压电传感器发射第一超声波信号；控制超声指纹模组检测接收到的所述第一超声波信号的第一信号强度；根据所述第一信号强度确定第一按压操作信息。这样通过压电传感器和超声指纹模组配合实现按压检测，从而无需在多个位置设置压电传感器。因此，本申请实施例减小了显示屏模组中检测压力的元器件占用的空间。与此同时，相对于现有技术设置多个压力检测元件，本申请实施例仅需要增加一个压电传感器，即可实现压力的检测，因此降低了成本。此外，还可以避免压力传感器与超声指纹模组设置位置的冲突。
可选地，在一些实施例中，所述控制超声指纹模组检测接收到的所述第一超声波信号的第一信号强度之后，所述方法还包括：
控制显示屏的目标显示区域对应的第一目标对象发射第二超声波信号，所述目标显示区域基于所述第一信号强度确定，所述第一目标对象为所述超声指纹模组的第三压电单元；
控制所述目标显示区域对应的第二目标对象检测接收到的所述第二超声波信号的第二信号强度，所述第二目标对象为所述超声指纹模组的第二压电单元；
根据所述第二信号强度和所述第一信号强度确定第二按压操作信息。
本申请实施例中，上述第二压电单元和第三压电单元均可以为超声指纹模组中的一个压电单元或者由多个压电单元组成的集合。其中，上述第二压电单元可以与第一压电单元为相同的压电单元，也可以为不同的压电单元。如图4所示，本申请实施例中，以上述第二压电单元与第一压电单元为相同的压电单元为例进行说明，在基于第一压电单元检测接收到的第一超声波信号的第一信号强度后，可以基于该第一信号强度确定用户手指按压的位置对应的显示区域，然后控制该显示区域对应的第三压电单元发射第二超声波信号，该显示区域对应的第一压电单元检测接收到的第二超声波信号的第二信号强度。此时，可以根据所述第二信号强度和所述第一信号强度确定第二按压操作信息，该第二按压操作信息可以包括在第二方向的坐标信息，即横向坐标信息。
需要说明的是，由于按压位置距离超声波发射端的距离不同，对超声波能量减弱的程度不同，因此，可以基于超声波能量减弱的程度确定横向的坐标信息。此外，为了避免按压压力对计算横坐标信息的影响，可以基于第一信号强度和第二信号强度的比值确定横坐标信息，以提高横坐标确定的准确性。换句话说，在本申请实施例中，所述根据所述第二信号强度和所述第一信号强度确定第二按压操作信息包括：
计算所述第二信号强度和所述第一信号强度的目标比值；
基于预设的关联关系，确定所述目标比值对应的第二按压操作信息；
其中，所述预设的关联关系用于表示所述第二信号强度和所述第一信号强度的比值信息与按压操作信息的关联关系，所述第二按压操作信息包括在第二方向的坐标信息。
本申请实施例中，可以将第二信号强度和第一信号强度的比值和横向的坐标位置做一个函数对应，形成上述关联关系。由于利用第二信号强度和所述第一信号强度的目标比值确定第二按压操作信息，从而可以使得超声指纹模组对应的区域作为按压检测区域，因此提高了按压检测区域的检测范围。当然在其他实施例中，还可以通过设置第一压电单元位于超声指纹模组远离压电传感器的一侧，从而提高了按压检测区域的检测范围。
需要说明的是，在本申请实施例中，可以基于上述第一按压操作信息和第二按压操作信息执行相应的功能。例如可以根据坐标信息将显示屏划分为四个区域，其中，不同的区域对应不同的功能，且可以设置不同按压的压力值大小对应不同的功能。假设设置两个压力等级，则可以实现八种功能的按压操作。
需要说明的是，本申请实施例提供的按压操作检测方法，执行主体可以为按压操作检测装置，或者该按压操作检测装置中的用于执行加载按压操作检测方法的控制模块。本申请实施例中以按压操作检测装置执行加载按压操作检测方法为例，说明本申请实施例提供的按压操作检测方法。
