具体实施方式
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，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1，图1是本发明实施例提供的第一种显示装置10的结构示意图。所述显示装置10包括感应层100和显示模组200，所述感应层100与所述显示模组200层叠设置，或者，所述感应层100内嵌于所述显示模组200，所述感应层100检测外部对所述显示模组200的压力，并用于指示所述显示模组200是否发生损坏，以及所述显示模组200发生损坏的部位。
其中，显示模组200为柔性显示模组200。
感应层100可以为超薄的压敏薄膜，也可以为压电薄膜。关于感应层100为压敏薄膜以及压电薄膜的具体实施方式参见后面的详细介绍。
在一些可能的实施方式中，显示模组200为封装完好的整体结构，感应层100与显示模组200层叠设置，即感应层100可以位于显示模组200的上面，也可以位于显示模组200的下面。当感应层100位于显示模组200的上面时，感应层100可以充当封装层，即感应层100一方面可以对显示模组200起到保护的作用，另一方面，还可以用于检测显示模组200外部对所述显示模组200的压力，并用于指示所述显示模组200是否发生损坏，以及所述显示模组200发生损坏的部位。由于感应层100位于显示模组200的上面，当外部压力作用于显示装置10时，直接作用于感应层100上，外部压力无需经过其他层结构传递至感应层100，换句话说，此时的感应层100对于外部压力作用更为敏感，因此，可以在确保感应层100具有较高检测精度的前提下，减小感应层100的厚度，有助于实现显示装置10的轻薄化设计。当感应层100位于显示模组200的下面时，通过按压显示模组200将压力传递至感应层100，再通过感应层100表现出来的不同现象可以更好的衡量外部对显示模组200施加的压力，从而有助于提高损坏检测的精度。
在另一些可能的实施方式中，感应层100内嵌于显示模组200内，即感应层100位于显示模组200任意相邻的两层结构之间，将感应层100内嵌于显示模组200，可以将感应层100和显示模组200作为一个整体一体化成型，有助于实现模块化设计，便于后续的安装以及拆卸更换等。且由于感应层100内嵌于显示模组200，可以使得感应层100更好的贴合于显示模组200。更进一步的，将感应 层100附着于显示模组200内，可以有效的避免感应层100从显示模组200上脱落下来，从而可以延长显示装置10的使用寿命。
进一步的，在其他一些可能的实施方式中，感应层100可以为一个整体的层结构，可以与显示模组200保持同等大小，从而可以检测显示模组200的任意部位是否发生损坏以及发生损坏时的具体部位。
请继续参阅图2，在另一些可能的实施方式中，感应层100也可以为间隔排布的若干个小的感应单元110组合而成，此时，由于相邻的感应单元110之间为间隔排布，相邻的感应单元110之间不会产生相互的挤压作用，可以很好的消除相邻感应单元110之间的应力，进而将感应层100与显示模组200之间的应力释放，有助于避免出现应力集中的问题，假设有显示模组200和感应层100之间存在应力集中的情况，那么显示模组200和感应层100之间的内应力可能会对外部压力产生干扰，可能会导致检测不准确的情况，因此，通过将若干个感应单元110间隔排布形成感应层100，可以解决显示模组200和感应层100之间的应力集中问题，进而提高显示装置10检测外部压力的检测精度。进而提高显示装置10对显示模组200是否发生损坏以及发生损坏时的部位的检测精度。
可选的，若干个感应单元110呈现阵列排布，以形成感应层100。当外部压力刚好施加于感应单元110时，通过感应单元110检测显示模组200外部对所述显示模组200的压力，并用于指示所述显示模组200是否发生损坏，以及所述显示模组200发生损坏的部位。当外部压力施加于相邻两个感应单元110之间的部位时，通过相邻两个感应单元110检测到的压力取平均值的方式来检测显示模组200外部对所述显示模组200的压力，并用于指示所述显示模组200是否发生损坏，以及所述显示模组200发生损坏的部位。当外部压力同时作用于多个相邻的感应单元110时，根据外部压力的方向与感应单元110的中心部位之间的距离大小分配权重系数，根据分配至多个感应单元110上的权重系数计算显示模组200外部对所述显示模组200的压力，并用于指示所述显示模组200是否发生损坏，以及所述显示模组200发生损坏的部位。且具体的，外部压力的方向与感应单元110的中心部位之间的距离越小，分配的权重系数越大。
举例而言，假设外部压力同时作用于相邻的第一感应单元110、第二感应单元110和第三感应单元110，外部压力的作用方向与第一感应单元110之间的距离为d1，外部压力的作用方向与第二感应单元110之间的距离d2，外部压力的作用方向与第三感应单元110之间的距离d3，当d1<d2<d3时，分配至第一感应单元110用于计算外部压力的权重系数为a1，分配至第二感应单元110用于计算外部压力的权重系数为a2，分配至第三感应单元110用于计算外部压力的权重系数为a3，其中，a1>a2>a3，且a1+a2+a3＝1。
本发明实施例提供的显示装置10包括感应层100和显示模组200，在一些可能的实施方式中，感应层100与显示模组200层叠设置，在另一些实施方式中，感应层100内嵌于显示模组200。其中，感应层100用于检测外部对显示模组200的压力，并用于指示显示模组200是否发生损坏，以及当显示模组200发生损坏时，指示显示模组200发生损坏的部位。通过设置感应层100来判断柔性显示模组200的损坏原因是人为操作不当引起的，还是柔性显示模组200自身品质问题出现局部显示异常或坏点，对柔性显示模组200的售后判定具有参考价值。
请继续参阅图3，图3是本发明实施例提供的第二种显示装置10的结构示意图。第二种显示装置10的结构示意图与第一种显示装置10的结构示意图基本相同，不同之处在于，所述感应层100为压电层，当所述显示模组200受到外部 压力时，所述感应层100会产生压电电流，所述显示装置10还包括控制器300，所述控制器300根据所述感应层100产生压电电流的大小判断所述显示模组200是否发生损坏。
其中，控制器300可以为微处理器，也可以为中央处理器。控制器300用于根据感应层100产生的压电电流的大小来判断显示模组200是否发生损坏的情况。具体的，由于感应层100为压电层，具有压电效应，当显示模组200受到外部压力作用时，感应层100上会产生微弱的电流信号，即为压电电流。压电电流会经过显示模组200中的集成电路将产生压电电流对应显示模组200上的坐标、根据压电电流大小获取到的外力值以及产生压电电流的时间都反馈到显示装置10做后台记录并将数据保留，以便于后续对显示装置10进行维护时，将产生压电电流对应显示模组200上的坐标、根据压电电流大小获取到的外力值以及产生压电电流的时间作为判断是人为损坏还是显示模组200本身的故障。
在一种可能的实施方式中，当所述显示模组200发生损坏时，所述控制器300还根据所述感应层100产生压电电流的部位判断所述显示模组200受到压力冲击的部位。
具体的，由于感应层100为压电层，受到外部压力作用时会产生压电电流，因此，感应层100产生压电电流的部位与显示模组200受到压力冲击的部位之间具有对应关系。当显示模组200受到外部压力作用时，感应层100上会产生微弱的压电电流。压电电流会经过显示模组200中的集成电路将产生压电电流对应显示模组200上的坐标反馈到显示装置10做后台记录并将数据保留。当需要对显示模组200进行损坏检测时，显示装置10后台记录的数据此时可以作为参考的依据，根据产生压电电流的部位就可以确定显示模组200发生损坏的部位。
请继续参阅图4，图4是本发明实施例提供的第三种显示装置10的结构示意图。第三种显示装置10的结构示意图与第一种以及第二种显示装置10的结构示意图基本相同，不同之处在于，当所述感应层100与所述显示模组200层叠设置时，所述感应层100和所述显示模组200之间设置有双面胶400，所述双面胶400用于将所述感应层100和所述显示模组200固定连接。
其中，所述双面胶400为超薄高回弹双面胶400。
在一种实施方式中，所述双面胶400为一整层的双面胶400，即双面胶400为一整块，用于将感应层100和显示模组200固定相连，使得感应层100与显示模组200紧密贴合，从而可以使得外部压力可以很好的通过显示模组200传递至感应层100，然后通过感应层100可以精确的检测到外部压力的大小。
在另一种实施方式中，所述双面胶400包括若干个间隔排布的胶体单元410。可选的，若干个间隔排布的胶体单元410呈现阵列排布。通过若干个间隔排布的胶体单元410将感应层100粘接于显示模组200上，由于相邻的胶体单元410之间没有直接接触，因此，可以很好的消除相邻胶体单元410之间产生的内应力，进而消除感应层100与显示模组200之间的内应力，有助于解决感应层100与显示模组200之间产生应力集中的问题，进而可以延长显示装置10的使用寿命。
更进一步的，对应显示模组200边缘部位设置的相邻胶体单元410之间的间隙为第一间隙，对应显示模组200的中间部位设置的相邻胶体单元410之间的间隙为第二间隙，第一间隙大于第二间隙。由于显示模组200的边缘部位与感应层100进行贴合时，更容易出现应力集中的问题，因此，当对应显示模组200边缘部位设置的相邻胶体单元410之间的第一间隙大于对应显示模组200中间部位设置的相邻胶体单元410之间的第二间隙时，可以更好的避免显示模组200边缘部 位设置的胶体单元410之间出现应力集中的问题，进而改善显示模组200边缘部位与感应层100进行贴合时的应力集中问题。
请继续参阅图5，图5是本发明实施例提供的第四种显示装置10的结构示意图。第四种显示装置10的结构示意图与第一种以及第二种显示装置10的结构示意图基本相同，不同之处在于，所述显示装置10还包括层叠设置的显示面板500和柔性盖板600，所述感应层100位于所述显示面板500远离所述柔性盖板600的一侧。
其中，柔性盖板600盖合于显示面板500的表面。柔性盖板600为聚酰亚胺材料(PI材料)。聚酰亚胺是综合性能最佳的有机高分子材料之一，耐高温达400℃以上，长期使用温度范围-200～300℃，部分无明显熔点，高绝缘性能。柔性盖板600构成显示装置10的部分外观结构，用于对显示面板500进行保护，充当封装层和保护层的作用。柔性盖板600和显示面板500之间可以通过透明光学胶固定连接。

在本实施例中，感应层100通过双面胶400固定于显示面板500远离柔性盖板600的表面。其中双面胶400可以为超薄高回弹双面胶400。由于感应层100相对于显示面板500远离柔性盖板600设置，当外部压力作用于柔性盖板600时，先通过柔性盖板600传递至显示面板500，然后再通过显示面板500传递至感应层100，通过感应层100就可以判断柔性显示面板500的损坏原因是人为操作不当引起的，还是柔性显示面板500自身品质问题出现局部显示异常或坏点，对柔性显示面板500的售后判定具有参考价值。且将感应层100相对于显示面板500远离柔性盖板600设置，可以避免感应层100对显示面板500形成遮挡，有助于提高显示装置10的显示效果。
请继续参阅图6，图6是本发明实施例提供的第五种显示装置10的结构示意图。第五种显示装置10的结构示意图与第一种以及第二种显示装置10的结构示意图基本相同，不同之处在于，所述显示装置10还包括层叠设置的显示面板500和柔性盖板600，所述感应层100内嵌于所述显示面板500。

在本实施例中，感应层100内嵌于显示面板500内。即感应层100可以位于显示面板500内任意相邻的两个层结构之间。此时，感应层100和显示面板500可以作为一个整体的结构一体化成型，便于后续的安装以及拆卸更换等。且将感应层100内嵌于显示面板500时，可以使得感应层100与柔性盖板600之间的距离更近，进而可以在确保显示装置10具有较高的检测精度的前提下，减小感应层100的厚度，从而实现显示装置10的轻薄化设计。
请继续参阅图7，图7是本发明实施例提供的第六种显示装置10的结构示意图。第六种显示装置10的结构示意图与第一种以及第二种显示装置10的结构示意图基本相同，不同之处在于，所述显示装置10还包括层叠设置的显示面板500和柔性盖板600，所述感应层100位于所述显示面板500和所述柔性盖板600之间。
其中，显示面板500为柔性显示面板500。柔性盖板600盖合于感应层100的表面，感应层100盖合于显示面板500的表面。柔性盖板600为聚酰亚胺材料 (PI材料)。柔性盖板600构成显示装置10的部分外观结构，用于对显示面板500进行保护，充当封装层和保护层的作用。柔性盖板600与感应层100之间以及感应层100与显示面板500之间可以通过透明光学胶固定连接。
在本实施例中，感应层100位于柔性盖板600和显示面板500之间。此时，可以使得感应层100与柔性盖板600之间的距离更近，当外部压力作用于柔性盖板600时，可以快速的传递至感应层100上，进而可以在确保显示装置10具有较高的检测精度的前提下，减小感应层100的厚度，从而实现显示装置10的轻薄化设计。
请继续参阅图8，图8是本发明实施例提供的第七种显示装置10的结构示意图。第七种显示装置10的结构示意图与第一种以及第二种显示装置10的结构示意图基本相同，不同之处在于，所述显示装置10还包括层叠设置的显示面板500和柔性盖板600，所述感应层100位于所述柔性盖板600远离所述显示面板500的一侧。
其中，显示面板500为柔性显示面板500。感应层100盖合于柔性盖板600的表面，柔性盖板600盖合于显示面板500的表面。柔性盖板600为聚酰亚胺材料(PI材料)。感应层100构成显示装置10的部分外观结构，与柔性盖板600一起用于对显示面板500进行保护，充当封装层和保护层的作用。感应层100与柔性盖板600之间以及柔性盖板600与显示面板500之间可以通过透明光学胶固定连接。
在本实施例中，柔性盖板600位于感应层100和显示面板500之间。此时，外部压力可以直接作用于感应层100，进而可以在确保显示装置10具有较高的检测精度的前提下，最大程度的减小感应层100的厚度，从而实现显示装置10的轻薄化设计。且由于感应层100位于柔性盖板600的表面，可以进一步的对柔性盖板600以及显示面板500形成保护，有助于延长显示装置10的使用寿命。
请继续参阅图9，图9是本发明实施例提供的第八种显示装置10的结构示意图。第八种显示装置10的结构示意图与第四种至第七种显示装置10的结构示意图基本相同，不同之处在于，所述显示面板500和所述柔性盖板600之间设置有第一光学胶450，所述第一光学胶450用于将所述显示面板500和所述柔性盖板600固定连接，所述显示面板500包括依次层叠设置的触控层510、第二光学胶520、偏光片530、发光层540、第三光学胶550和基板560，所述触控层510相对于所述第二光学胶520邻近所述柔性盖板600设置。
其中，第一光学胶450为透明光学胶。在一种实施方式中，第一光学胶450为一整层胶体，位于柔性盖板600和显示面板500之间，以将柔性盖板600和显示面板500固定连接。
其中，触控层510包括交叉设置的驱动电极和感应电极，用于实现显示装置10的触控功能。
第二光学胶520也为透明光学胶，第二光学胶520可以为一整层的光学胶，以将触控层510和偏光片530固定连接。第二光学胶520也可以为若干个间隔排布的胶体单元410组合形成，此时，有助于消除相邻胶体单元410之间形成的内应力，进而消除触控层510和偏光片530之间的内应力，延长显示装置10的使用寿命。
其中，发光层540为有源矩阵有机发光二极体(Active-matrix organic light-emitting diode，OLED)发光器件层。
第三光学胶550也为透明光学胶，第三光学胶550可以为一整层的光学胶， 以将发光层540和基板560固定连接。第三光学胶550也可以为若干个间隔排布的胶体单元410组合形成，此时，有助于消除相邻胶体单元410之间形成的内应力，进而消除发光层540和基板560之间的内应力，延长显示装置10的使用寿命。
其中，基板560为柔性基板560，可以为聚酰亚胺(PI)材料，也可以为聚对苯二甲酸乙二醇酯(PET)材料。
请继续参阅图10，图10是本发明实施例提供的第九种显示装置10的结构示意图。第九种显示装置10的结构示意图与第一种显示装置10的结构示意图基本相同，不同之处在于，所述感应层100为压敏层110，当所述显示模组200受到外部压力，且压力值大于预设阈值时，所述感应层100会呈现出预设颜色，所述预设颜色用于指示所述显示模组200发生损坏。
在一种可能的实施方式中，所述感应层100呈现出的预设颜色的深浅用于指示所述显示模组200的受损程度。
举例而言，当感应层100为压敏层110，显示模组200受到外部压力时，感应层100会呈现出红色，感应层100呈现深红色表示对应部位的显示模组200受到较大的外部压力，浅红色表示对应部位的显示模组200受到较小的外部压力。此时，预设颜色为同一种颜色。
可以理解的，在其他实施方式中，感应层100可以呈现出不同颜色，且不同颜色表示不同压力值大小。比如，显示模组200受到外部压力时，感应层100会呈现出红、橙、黄、绿等颜色，感应层100呈现红色表示对应部位的显示模组200受到的外部压力最大，其次是橙色，再次是黄色，最后是绿色。此时，预设颜色为不同种颜色。
在另一种可能的实施方式中，所述感应层100呈现出的预设颜色的面积大小用于指示所述显示模组200受损的面积大小。
由于感应层100为压敏层110，在外部压力作用下会呈现出预设颜色，因此，感应层100呈现出的预设颜色的面积大小与显示模组200受损的面积大小之间具有对应关系。
请继续参阅图11，图11是本发明实施例提供的第十种显示装置10的结构示意图。第十种显示装置10的结构示意图与第九种显示装置10的结构示意图基本相同，不同之处在于，所述压敏层110包括依次层叠设置的第一薄膜层111、隔离层112和第二薄膜层113，所述隔离层112用于对所述第一薄膜层111和所述第二薄膜层113形成隔离，所述第一薄膜层111由第一微粒111a组成，所述第二薄膜层113由第二微粒113a组成，当压力值大于预设阈值时所述隔离层112破裂，所述第一微粒111a和所述第二微粒113a发生反应以呈现出所述预设颜色。
其中，第一微粒111a和第二微粒113a为化学微粒，当外部压力作用于显示模组200上时，第一微粒111a和第二微粒113a之间的隔离层112会破裂，进而使得第一微粒111a和第二微粒113a产生不可逆的化学反应，并呈现出特定的颜色。
请继续参阅图12，图12是本发明实施例提供的第十一种显示装置10的结构示意图。第十一种显示装置10的结构示意图与第十种显示装置10的结构示意图基本相同，不同之处在于，所述显示装置10还包括层叠设置的显示面板500和柔性盖板600，所述显示面板500和所述柔性盖板600之间设置有第一胶体521，所述第一胶体521用于将所述显示面板500和所述柔性盖板600固定连接，所述显示面板500包括依次层叠设置的触控层510、第二胶体522、偏光片530、 发光层540、第三胶体551和基板560，所述触控层510相对于所述第二胶体522邻近所述柔性盖板600设置，所述感应层100位于所述显示面板500远离所述柔性盖板600的一侧，且所述第一薄膜层111相对于所述第二薄膜层113邻近所述基板560设置，所述第一薄膜层111和所述基板560之间通过双面胶400固定连接。
其中，第一胶体521为透明光学胶。在一种实施方式中，第一胶体521为一整层胶体，位于柔性盖板600和显示面板500之间，以将柔性盖板600和显示面板500固定连接。
其中，触控层510包括交叉设置的驱动电极和感应电极，用于实现显示装置10的触控功能。
第二胶体522也为透明光学胶，第二胶体522可以为一整层的光学胶，以将触控层510和偏光片530固定连接。第二胶体522也可以为若干个间隔排布的胶体单元410组合形成，此时，有助于消除相邻胶体单元410之间形成的内应力，进而消除触控层510和偏光片530之间的内应力，延长显示装置10的使用寿命。
其中，发光层540为有源矩阵有机发光二极体(Active-matrix organic light-emitting diode，OLED)发光器件层。
第三胶体551也为透明光学胶，第三胶体551可以为一整层的光学胶，以将发光层540和基板560固定连接。第三胶体551也可以为若干个间隔排布的胶体单元410组合形成，此时，有助于消除相邻胶体单元410之间形成的内应力，进而消除发光层540和基板560之间的内应力，延长显示装置10的使用寿命。
其中，基板560为柔性基板560，可以为聚酰亚胺(PI)材料，也可以为聚对苯二甲酸乙二醇酯(PET)材料。所述基板560和所述第一薄膜层111之间通过双面胶400固定连接，所述双面胶400为超薄高回弹双面胶400。
请继续参阅图13，图13是本发明实施例提供的第十二种显示装置10的结构示意图。第十二种显示装置10的结构示意图与第九种显示装置10的结构示意图基本相同，不同之处在于，所述显示装置10还包括层叠设置的显示面板500和柔性盖板600，所述显示面板500和所述柔性盖板600之间设置有第一胶体521，所述第一胶体521用于将所述显示面板500和所述柔性盖板600固定连接，所述显示面板500包括依次层叠设置的触控层510、第二胶体522、偏光片530、发光层540、第三胶体551和基板560，所述触控层510相对于所述第二胶体522邻近所述柔性盖板600设置，所述感应层100位于所述基板560和所述发光层540之间。
其中，感应层100与基板560之间以及感应层100与发光层540之间均是通过光学胶连接。此时，感应层100与柔性盖板600之间的距离更近，当外部压力作用于柔性盖板600，可以较快的通过柔性盖板600传递至感应层100，然后再通过感应层100检测外部压力的大小，进而指示显示模组200是否发生损坏以及发生损坏时的受损部位。
请继续参阅图14，图14是本发明实施例提供的第十三种显示装置10的结构示意图。第十三种显示装置10的结构示意图与前面任意一种显示装置10的结构示意图基本相同，不同之处在于，所述感应层100的中间部位101对应第一压力阈值，所述感应层100的边缘部位102对应第二压力阈值，所述第一压力阈值大于所述第二压力阈值。
具体的，由于显示模组200的中间部位应力分布较为均匀，显示模组200的边缘部位应力分布不均匀，因此，相对于显示模组200的中间部位而言，显示模 组200的边缘部位比较容易遭受破坏。换句话说，显示模组200的边缘部位对于外部压力的表现更为敏感。当感应层100的中间部位101对应的第一压力阈值大于感应层100的边缘部位102对应的第二压力阈值时，可以更为准确的检测出显示模组200的中间部位以及边缘部位对外部压力的不同承受能力，可以增加显示装置10对外部压力检测的灵敏度。
在一种实施方式中，感应层100的中间部位101对应的第一压力阈值为恒定值，感应层100的边缘部位102对应的第二压力阈值也为恒定值，此时，感应层100的制备更为方便简单，同时也能够满足对于外部压力的检测精度。
在另一种实施方式中，感应层100的中间部位101对应的第一压力阈值为渐变的数值，感应层100的边缘部位102对应的第二压力阈值也为渐变的数值，感应层100的压力阈值从感应层100的中间部位101朝向感应层100的边缘部位102逐渐减小。在一种可能的实施方式中，感应层100的压力阈值从感应层100的中间部位101朝向感应层100的边缘部位102呈现均匀减小，从而可以更加贴合显示模组200本身应力分布的实际情况，有助于提高显示装置10对于外部压力检测的精确度。
请继续参阅图15，图15是本发明实施例提供的第十四种显示装置10的结构示意图。第十四种显示装置10的结构示意图与第十三种显示装置10的结构示意图基本相同，不同之处在于，所述感应层100的中间部位101和所述感应层100的边缘部位102的厚度保持一致，所述感应层100的中间部位101的密度小于所述感应层100的边缘部位102的密度。
具体的，当感应层100各个部位对应的厚度保持均匀一致时，可以确保整个显示装置10的厚度较为均匀，进而有助于消除显示装置10内部的应力集中问题。且当感应层100的中间部位101的密度小于感应层100的边缘部位102的密度时，由于感应层100的中间部位101的材料更为稀疏，感应层100的边缘部位102的材料更为密集，因此，感应层100的中间部位101受到外部压力作用时，对于外部压力的敏感程度较低，感应层100的边缘部位102受到外部压力作用时，对于外部压力的敏感程度较高，也就是说，感应层100的中间部位101对应的压力阈值大于感应层100的边缘部位102的压力阈值。由于显示模组200的中间部位应力分布较为均匀，显示模组200的边缘部位应力分布不均匀，因此，相对于显示模组200的中间部位而言，显示模组200的边缘部位比较容易遭受破坏。通过将感应层100的边缘部位102的密度设置的更大一些，可以使得感应层100的边缘部位102对于外部压力的检测更为灵敏。
请继续参阅图16，图16是本发明实施例提供的第十五种显示装置10的结构示意图。第十五种显示装置10的结构示意图与第十三种显示装置10的结构示意图基本相同，不同之处在于，所述感应层100的中间部位101和所述感应层100的边缘部位102的密度保持一致，所述感应层100的中间部位101的厚度小于所述感应层100的边缘部位102的厚度。
具体的，当感应层100的中间部位101的密度与边缘部位的密度保持一致时，可以边缘感应层100的制备，有助于简化感应层100的制备工艺。
进一步的，由于显示模组200的中间部位应力分布较为均匀，显示模组200的边缘部位应力分布不均匀，因此，相对于显示模组200的中间部位而言，显示模组200的边缘部位比较容易遭受破坏。当感应层100的中间部位101的厚度小于感应层100的边缘部位102的厚度时，有助于降低感应层100的中间部位101对应外部压力的敏感度，提高感应层100的边缘部位102对应外部压力的敏感度， 此时，可以更加贴合显示模组200内部应力分布的实际情况，进而提高显示装置10对于外部压力检测的灵敏度。

请继续参阅图19，图19是本发明实施例提供的第三种电子设备1的结构示意图。第三种电子设备1的结构示意图与第一种电子设备1的结构示意图基本相同，不同之处在于，所述电子设备1还包括中框60和电池70，所述中框60部分收容于所述第一壳体30以及所述第二壳体40内，所述中框60相对于所述电池70邻近所述显示装置10设置，所述电池70用于为所述显示装置10供电。
