背景技术
近年来，随着OLED显示技术的出现和不断发展，柔性显示、柔性压感触控技术应运而生。目前，在显示领域尤其是手机或平板等领域中，感测显示面板受到的压力的压力传感器通常需要形成在额外的玻璃基底上，之后将带有压力传感器的玻璃基底结合到柔性显示面板中，这种方式由于增加了玻璃基底而使柔性显示面板的厚度增大。

具体实施方式
为使本领域技术人员更好地理解本公开的技术方案，下面结合附图和具体实施方式对本公开作进一步详细描述。
根据本公开的一个方面，提供了一种柔性显示屏。如图1所示，该柔性显示屏包括基底10、背膜1、压力传感器2。背膜1层叠地设置在基底10的背离柔性显示屏出光面的侧面上，压力传感器2层叠地设置在背膜1的背离基底10的侧面上，并且构造为输出与施加在柔性显示屏上的力有关的信号。
由于本示例性实施例中的柔性显示屏中的压力传感器2设置在背膜1上，因此无需选用一个单独的基板(例如，相关技术中的玻璃基底)来形成压力传感器2，从而使得所形成的具有压力传感器2的柔性显示屏较为轻薄，同时还可以降低工艺成本。
在本公开的示例性实施例中，压力传感器2为电容式压力传感器，如图1所示，其包括沿相对于背膜1背离基底10的方向依次设置的第一电极21、介质层23、第二电极22。第二电极22为整层结构的接地电极，且与柔性显示屏的中框7(其在图1中仅被示意性地示出左侧的一部分)共用，因此可以使得柔性显示屏较为轻薄。压力传感器2的各层结构(即第一电极21、介质层23、第二电极22)可以通过印刷工艺完成，该工艺简单，且良率较高。在此需要说明的是，第一电极21与介质层23之间，以及介质层23与第二电极22之间均可以采用双面胶进行粘结，由此简单方便地形成压力传感器2。
在本公开的示例性实施例中，压力传感器2中的介质层23的材料为泡棉，其中，泡棉的材料可以是EPDM(三元乙丙橡胶)、PU(聚氨酯)等绝缘材料。由于泡棉的弹性较好，在对压力传感器2施压时，泡棉发生形变，从而可以改变第一电极21和第二电极22二者之间的距离，根据电容公式：C＝εS/d，进而可以得到压力传感器2的电容变化。应当说明的是，正常情况下，电容公式为C＝εS/4πkd，但如果平行的两个极板的间距d远小于它们的宽度和长度，则电容公式近似为C＝εS/d，其中，ε为极板间介质的介电常数，S为极板面积，d为极板间的距离。
在本公开的示例性实施例中，如图2所示，柔性显示屏还包括散热层3，该散热层3位于介质层23和第二电极22之间，用于将柔性显示屏所产生的热量进行释放。例如，当柔性显示屏为手机时，这种情况下，散热层3主要用于对手机的电池所产生的热量进行释放。散热层3的材料可以包括铜和石墨。当然，也不局限于这两种材料，还可以使用其他具有热量释放功能的材料。
在本公开的示例性实施例中，为了避免柔性显示屏在显示时看到压力传感器2，如图3所示，在背膜1与压力传感器2之间设置遮光层4，或者，如图4所示，在基底10与背膜1之间设置遮光层4。遮光层4的材料可以为油墨，当然也可以采用其他不透光的材料，例如黑色树脂材料。
在本公开的示例性实施例中，背膜的材料包括：PI(聚酰亚胺)、PET(聚对苯二甲酸乙二醇酯)、TAC(三醋酸纤维素)中任意一种高分子薄膜材料。当然，也不局限于以上几种材料，也可以采用其他的柔性材料。
在本公开的示例性实施例中，柔性显示屏可以为有机电致发光二极管显示屏，因此，如图5所示，该柔性显示屏还包括：位于基底10上的多个像素单元5，每个像素单元5中包括有机电致发光二极管51。
在本公开的示例性实施例中，如图5所示，在像素单元5的出光面侧还设置有触控单元6，以用于实现触控，通常触控单元6 包括驱动电极和感应电极。此时，本示例性实施例中的柔性显示屏可以实现触控在X、Y、Z三个方向上的检测，实现3D触控功能。具有上述构造的整个模组较为轻薄，有利于柔性显示屏的弯折。
根据本公开的另一个方面，提供了一种显示装置。该显示装置包括上述柔性显示屏，关于柔性显示屏的构造，此处不详细描述。
在本公开的示例性实施例中，该显示装置可以包括：OLED面板、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。
可以理解的是，以上实施方式仅仅是为了说明本公开的原理而采用的示例性实施方式，然而本公开并不局限于此。对于本领域内的普通技术人员而言，在不脱离本公开的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本公开的保护范围。
