发明人通过研究以解决如何在显示面板硬件改动较小的情况下实现探测精度较高的压力感应的问题。
本发明实施例提供的一种显示装置，如图1所示，该显示装置包括：相对而置的阵列基板100和对向基板200，以及设置于阵列基板100与对向基板200之间的自电容电极300。该显示装置还包括：设置于阵列基板100下方的背光模组400，以及形成在该背光模组400的背面的背光金属500。背光金属500与自电容电极300相对设置，可以在彼此之间形成电容结构。
该自电容电极300为触控电极图案的一种示例，包括排列为阵列的多个电极，每个电极例如可以单独寻址、检测，例如通过铟锡氧化物(ITO)等透明导电材料形成。背光金属500为相对电极的一种示例，其可以整面形成，也可以对应于上述触控电极图案形成为例如多个彼此平行的条状电极，条状电极之间具有间隙。相对电极不限于以金属形成，例如可以通过ITO等导电材料形成。
例如，阵列基板100包括多条栅线和多条数据线，这些栅线和数据线彼此交叉由此限定了排列为矩阵的多个像素单元，每个像素单元包括作为开关元件的薄膜晶体管和用于控制液晶的排列方向的像素电极和公共电极。
在触控检测时间段，同时对自电容电极300和背光金属500加载触控检测信号，通过检测各自电容电极300的电容值变化以判断触控位置；在压力检测时间段，对自电容电极300或背光金属500加载触控检测信号，且通过检测自电容电极300的电容值变化以判断触控位置压力大小的触控侦测芯片。
本发明实施例提供的上述显示装置，利用触摸屏中的自电容电极300和背光金属500之间形成的电容结构实现压力感应的功能，对于显示装置的结构设计改动较小，不会受到装配公差的限制，有利于实现更好的探测精度，且有利于节省制作成本。
在本发明实施例提供的上述显示装置中，如图1所示，包括阵列基板100和对向基板200的触摸屏和其下方的背光模组400之间具有间距为d的空气间隙10。当触摸屏被按压时，该空气间隙10被压缩使得间距d减小，这样触摸屏中自电容电极300与背光金属500之间形成的电容就会增大，通过检测此电容值的变化就可以确定出压力的大小。
例如，在本发明实施例提供的上述显示装置中，为了防止在按压触摸屏时，背光模组400背面的背光金属500发生形变导致一部分压力传递出去而没有全部体现在空气间隙的间距d减小上。如图2所示，在另一个实施例的显示装置中，例如，可以在背光模组400外侧的电子设备(例如手机)的中框600与背光模组400的背光金属500之间填充支撑层700，支撑层700与设置在背光模组400背面的背光金属500相邻设置，以支撑背光金属500避免其发生形变。该支撑层700的材料选用高硬度的绝缘材料为佳，例如PET或PC等。该支撑层700为外侧附着层的一个示例。
例如，本发明实施例提供的上述显示装置中与自电容电极300形成电容结构的背光金属500例如可以采用包覆在背光模组400外侧的金属框，也可以采用贴覆于背光模组400背面的金属贴片，在此不做限定。
图6示出了本发明再一个实施例提供的显示装置，该实施例与图1所示的实施例的区别在于与电容电极300相对设置的相对电极非设置在背光模组400的背面，而是设置在背光模组400与阵列基板100相邻的一侧，并且在包括阵列基板100和对向基板200的触摸屏和其下方的背光模组400之间仍然具有间距为d的空气间隙10。
本发明实施例提供的上述显示装置中的自电容电极300的具体结构可以有多种实现方式。例如，可以采用阵列基板100中的公共电极层复用自电容电极300，即各自电容电极300组成阵列基板上的公共电极层。在将公共电极层的结构进行变更分割以形成自电容电极时，那么对于阵列基板制备工艺，不需要增加额外的工艺，可以节省生产成本，提高生产效率。例如，各自电容电极300也可以独立于阵列基板中的公共电极层独立形成，如制备于阵列基板的叠层结构之上。
下面以采用公共电极层复用作为自电容电极300为例，对本发明实施例提供的上述显示装置如何实现触控侦测和压力感应的具体实现方式进行详细的介绍。
在本发明实施例提供的上述显示装置中，例如，为了减少显示和触控信号之间的相互干扰，需要采用触控和显示阶段分时驱动的方式。例如，还可以将显示驱动芯片和触控侦测芯片整合为一个芯片，进一步降低生产成本。
如图3和图4所示的驱动时序图中，一般将显示装置中每一帧(V-sync) 的时间分成显示时间段(Display)、触控检测时间段(Touch)和压力检测时间段(Force)。
在显示时间段(Display)，如图3和图4所示，对显示装置中的每条栅极信号线Gate依次施加栅扫描信号，对数据信号线Source施加灰阶信号；当采用公共电极层复用自电容电极Cm时，与各自电容电极Cm连接的触控侦测芯片向各自电容电极Cm分别施加公共电极信号，以实现液晶显示功能。此时，与背光金属BL连接的触控侦测芯片一般也会向背光金属BL施加公共电极信号。
在触控检测时间段(Touch)，如图3和图4所示，触控侦测芯片同时对自电容电极Cm和背光金属BL加载触控检测信号。此时，在触控按压时造成的自电容电极Cm和背光金属BL之间距离的变化不会带来两者之间形成的电容结构的充放电，即不会对自电容电极Cm上的探测信号造成影响。因此，可以根据自容的检测原理，通过检测各自电容电极Cm的电容值变化以判断触控位置，实现触控侦测功能。
进一步地，在触控检测时间段(Touch)，为了避免阵列基板中的栅线Gate和数据线Source与自电容电极Cm之间产生对地电容从而影响触控检测的准确性，如图3和图4所示，可以在触控检测时间段对阵列基板中的栅线Gate和数据线Source加载与触控检测信号相同的电信号，这样可以消除栅线Gate和数据线Source与自电容电极Cm之间的对地电容，便于提高触控检测的准确性。
在压力检测时间段(Force)，触控侦测芯片对自电容电极Cm或背光金属BL加载触控检测信号，此时，在触控按压时造成的自电容电极Cm和背光金属BL之间距离的变化会带来两者之间形成的电容结构的充放电，即对自电容电极上的探测信号造成影响，因此可以通过检测自电容电极的电容值变化以判断触控位置压力大小，实现压力感应功能。
例如，在压力检测时间段(Force)触控侦测芯片对于自电容电极和背光金属加载的信号可以采用以下两种方式：
第一种方式，如图3所示。在压力检测时间段，触控侦测芯片对自电容电极Cm加载触控检测信号；同时对背光金属BL加载固定值信号，即背光金属BL此时的电平相对固定。这样，在触控按压时造成的自电容电极Cm 和背光金属BL之间距离的变化会带来两者之间形成的电容结构的充放电，该充放电过程造成的影响会计入自电容电极的探测信号量中，假设此时得到的探测信号量为b，而在触控检测时间段(Touch)通过自容的检测原理，通过手指与自电容电极之间产生的电容探测到自电容电极的探测信号量假设为a，则由于压力而产生的探测信号量f＝b-a。f越大则表明压力值越大，通过上述方式可以确定出压力值。
进一步地，在第一种方式中，为了避免在压力检测时间段阵列基板中的栅线Gate和数据线Source与自电容电极Cm之间产生对地电容从而影响压力感应的准确性，在具体实施时，如图3所示，在压力检测时间段，可以对阵列基板中的栅线Gate和数据线Source加载与所述触控检测信号相同的电信号，这样可以消除栅线Gate和数据线Source与自电容电极Cm之间的对地电容，便于提高压力感应的准确性。
第二种方式，如图4所示。在压力检测时间段，触控侦测芯片对背光金属BL加载触控检测信号；同时对自电容电极Cm加载固定值信号，即自电容电极Cm此时的电平相对固定。这样，在触控按压时造成的自电容电极Cm和背光金属BL之间距离的变化会带来两者之间形成的电容结构的充放电，利用互容检测原理，检测自电容电极的信号变化量，可以确定出自电容电极和背光金属之间的电容值，从而计算出压力的大小。
进一步地，在第二种方式中，为了避免在压力检测时间段阵列基板中的栅线Gate和数据线Source与自电容电极Cm之间产生对地电容从而影响压力感应的准确性，在具体实施时，如图4所示，在压力检测时间段，可以对阵列基板中的栅线Gate和数据线Source加载固定值电信号，这样可以消除栅线Gate和数据线Source与自电容电极Cm之间的对地电容，便于提高压力感应的准确性。
基于同一发明构思，本发明实施例还提供了一种上述显示装置的驱动方法，如图5所示，该方法包括以下步骤。
S501、在触控检测时间段，同时对自电容电极和背光金属加载触控检测信号，通过检测各自电容电极的电容值变化以判断触控位置；
S502、在压力检测时间段，对自电容电极或背光金属加载触控检测信号，且通过检测自电容电极和背光金属之间的电容值变化以判断触控位置压力大 小。
例如，在本发明实施例提供的上述显示装置的驱动方法中，在执行步骤S501时，还可以执行如下步骤：在触控检测时间段，对阵列基板中的栅线和数据线加载与触控检测信号相同的电信号。这样可以消除栅线和数据线与自电容电极之间的对地电容，便于提高触控检测的准确性。
例如，在本发明实施例提供的上述显示装置的驱动方法中，步骤S501中对自电容电极或背光金属加载触控检测信号，例如一种实现方式为：在压力检测时间段，对自电容电极加载触控检测信号，同时对背光金属加载固定值信号。
进一步地，在本发明实施例提供的上述显示装置的驱动方法中，步骤S501采用上述方式实现时，还可以包括以下步骤：在压力检测时间段，对阵列基板中的栅线和数据线加载与触控检测信号相同的电信号。这样可以消除栅线和数据线与自电容电极之间的对地电容，便于提高压力感应的准确性。
例如，在本发明实施例提供的上述显示装置的驱动方法中，步骤S501中对自电容电极或背光金属加载触控检测信号，例如另一种实现方式为：在压力检测时间段，对背光金属加载触控检测信号，同时对自电容电极加载固定值信号。
进一步地，在本发明实施例提供的上述显示装置的驱动方法中，步骤S501采用上述方式实现时，还可以包括以下步骤：在压力检测时间段，对阵列基板中的栅线和数据线加载固定值电信号。这样可以消除栅线和数据线与自电容电极之间的对地电容，便于提高压力感应的准确性。
本发明实施例提供的上述显示装置及其驱动方法，包括相对而置的阵列基板和对向基板，设置于阵列基板与对向基板之间的自电容电极，设置于阵列基板下方的背光模组背面的背光金属；其中，背光金属与自电容电极形成电容结构。在触控检测时间段，同时对自电容电极和背光金属加载触控检测信号，此时，在触控按压时造成的自电容电极和背光金属之间距离的变化不会带来两者之间形成的电容结构的充放电，即不会对自电容电极上的探测信号造成影响，因此，可以根据自容的检测原理，通过检测各自电容电极的电容值变化以判断触控位置，实现触控侦测功能。在压力检测时间段，对自电容电极或背光金属加载触控检测信号，此时，在触控按压时造成的自电容电 极和背光金属之间距离的变化会带来两者之间形成的电容结构的充放电，即对自电容电极上的探测信号造成影响，因此可以通过检测自电容电极的电容值变化以判断触控位置压力大小，实现压力感应功能。本发明实施例提供的上述显示装置，利用触摸屏中的自电容电极和背光金属之间形成的电容结构实现压力感应的功能，对于显示装置的结构设计改动较小，不会受到装配公差的限制，有利于实现更好的探测精度，且有利于节省制作成本。
本发明的另一个实施例提供了一种电子设备，该电子设备包括上述任一的显示装置。该电子设备例如可以为手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
