具体实施方式
下面将结合本申请实施例中的附图，对本申请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申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。若本申请实施例中有涉及“第一”、“第 二”等的描述，则该“第一”、“第二”等的描述仅用于描述目的，而不能理解为指示或暗示其相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。另外，各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本申请要求的保护范围之内。
请参阅图1，本申请一实施例提供的一种柔性显示装置100，包括柔性显示面板10、机壳20、透明支撑部30及光学指纹模组40；
所述机壳20用于承载所述柔性显示面板10，所述柔性显示面板10可为液晶显示面板(TFT-LCD)或者OLED(Organic Light-Emitting Diode，有机发光二极管)显示面板。
所述柔性显示面板10用于发射光线，当柔性显示面板10为液晶显示面板时，背光源可促使液晶像素单元成像，并且使得液晶显示面板发射光线，其中，发射光线以背光源为光源起始点，穿过各个液晶像素单元之间的缝隙，发射到液晶显示面板的外部环境。当柔性显示面板10为OLED显示面板时，OLED显示面板内若干OLED发光单元组成的发光层产生所述发射光线，其中，发射光线以发光层为光源起始点，穿过各个OLED像素单元之间的缝隙，发射到显示面板的外部环境。
当所述柔性显示面板10被按压物按压时，所述发射光线被所述按压物阻挡而反射回所述柔性显示面板10内，所述反射光线被光学指纹模组40接收，所述光学指纹模组40进而可根据所述反射光线生成指纹图像，对所述按压物的指纹信息进行识别。
所述按压物为可以为手指或脚趾等具有特定纹路的身体部位，又或者为具有特定纹路的物体。
为了使所述反射光线能够更好的被光学指纹模组40接收，提高生成的指纹图像质量，所述机壳20朝向所述柔性显示面板10的表面开设有透光槽， 且所述光学指纹模组40收容于所述透光槽远离所述柔性显示面板10的一端，可以理解的是，所述透光槽可允许更多反射光线穿过所述透光槽被所述光学指纹模组40接收，而不被所述机壳20遮挡，从而使所述反射光线能够更好的被光学指纹模组40接收，提高了生成的指纹图像质量，提高解锁速度。
但是由于所述柔性显示面板10是柔性的、可弯折的，当所述按压物按压所述柔性显示面板10的指纹采集区域时，所述指纹采集区域会发生形变，造成指纹成像质量较差，解锁速度较慢或者无法解锁。
因此为了消除所述指纹采集区域的形变对指纹成像质量造成的不良影响，在本实施例中，在所述柔性显示装置100中设置有透明支撑部30，所述透明支撑部30安装于所述机壳20，所述透明支撑部30位于所述透光槽靠近所述柔性显示面板10的一端，且所述透明支撑部30的一表面与所述柔性显示面板10接触，以支撑所述柔性显示面板10。当所述按压物按压所述柔性显示面板10的指纹采集区域时，由于所述透明支撑部30具有预设硬度和刚度，所述透明支撑部30可在一定程度上抵消掉所述按压物对柔性显示面板10的按压力，对所述指纹采集区域起到支撑作用，消除所述指纹采集区域的形变对指纹成像质量造成的不良影响，提高了指纹成像质量。
进一步地，为了使所述反射光线能够更好的被光学指纹模组40接收，将所述光学指纹模组40与所述透明支撑部30间隔设置，以形成有透光空间24，所述透光空间24可允许更多发射光线顺利穿过所述透光空间24被所述光学指纹模组40接收，而不被所述机壳20遮挡，从而使所述反射光线能够更好的被光学指纹模组40接收，提高了生成的指纹图像质量，提高解锁速度。
在本实施例中，通过将所述透明支撑部30设置于所述透光槽靠近所述柔性显示面板10的一端，且所述透明支撑部30的一表面支撑所述柔性显示面板10，当所述按压物按压所述柔性显示面板10的指纹采集区域时，由于所述透明支撑部30具有预设硬度和刚度，所述透明支撑部30可在一定程度上抵 消掉所述按压物的对柔性显示面板10的按压力，对所述指纹采集区域起到支撑作用，消除所述指纹采集区域的形变对指纹成像质量造成的不良影响，提高了指纹成像质量，与用户预存指纹图形匹配度高，进而提高了指纹解锁的准确度和速度。
所述柔性显示面板10包括盖板、触控电极层、显示功能膜层及承载基底。
所述承载基底作为承载所述盖板、触控电极层、显示功能膜层的衬底，所述承载基底上依次设置有所述盖板、触控电极层、显示功能膜层。
所述盖板包括超薄玻璃层及基材，所述超薄玻璃层用于贴附于所述柔性显示屏上，所述超薄玻璃层具有可弯折性；由于所述超薄玻璃层的超薄特性，使其具有良好的弯折特性，所述超薄玻璃层在良好可弯折性的基础上，同时可具有较高硬度和/或刚度，因此所述超薄玻璃层使所述柔性显示面板具有耐摔和恢复性等特性的基础上，也是可在一定程度上抵消掉所述按压物的对柔性显示面板的按压力，减少所述指纹采集区域的形变对指纹成像质量造成的不良影响，提高指纹成像质量。
所述基材形成于所述超薄玻璃层上，所述基材用于提高所述盖板的硬度。由于所述基材形成于所述超薄玻璃层且正对使用用户，所述基材在具有预设硬度的同时，可具有耐刮、耐磨的特性。进一步地，所述基材的材料为有机材料时，使所述基材具备弯折特性，可进一步提高所述盖板的可弯折性。
所述触控电极层包括多个触控电极，多个所述触控电极分别沿第一方向间隔预设距离排列设置；多个所述触控电极分别沿第二方向间隔预设距离排列设置；所述第一方向和所述第二方向相互垂直，多个所述触控电极呈阵列式排布。
所述显示功能膜层包括发光层、薄膜晶体管层及偏光层。所述偏光层设置于所述发光层朝向所述触控电极层的一侧面。所述发光层与所述偏光层之间的连接可采用光学胶固定连接、嵌设压合固定连接或层膜镀设等连接方式。
所述发光层作为发射光线源用于产生所述发射光线，在本实施例中，所述发光层产生的所述发射光线应用于所述柔性显示装置100的光学指纹模组40，即所述光学指纹模组40可接收的所述反射光线，生成指纹图像。
所述发光层包括有机功能层、阴极及阳极。其中，所述有机功能层层叠设置于所述阴极与所述阳极之间，以产生所述发射光线。其中，所述有机功能层由基质材料掺杂一定比例的有机发光材料制备而成。在施加外部电压的情况下，所述阳极的空穴向所述有机功能层迁移，所述阴极的电子向所述有机功能层迁移，电子与空穴在所述有机功能层中相遇形成电子-空穴对，电子从激发态跃迁为基态，以辐射光子的形式释放能量，从而产生电致发光。其中的有机发光材料可以选择有机小分子材料或有机高分子材料，以实现电致发光。
所述薄膜晶体管层设置于所述发光层的一侧面，用以驱动所述发光层。所述薄膜晶体管层结构，以及如何扫描驱动所述发光层产生所述发射光线，是现有技术手段，在此不再赘述。
所述偏光层为圆偏光层，用于将发光层产生的发射光学由非偏振光转化为偏振光。
所述透明支撑部30为透明玻璃、亚克力有机薄膜(PMMA)等透光材质所形成，所述透明支撑部30可以受可见光、红外光、或是紫外光所穿透。当所述柔性显示面板10被按压时，所述发射光线被按压物阻挡而反射回所述柔性显示面板10内形成反射光线，所述反射光线经过所述透明支撑部30透射而被所述光学指纹模组40接收。
所述光学指纹模组40包括线路基板、支架、镜片、指纹芯片、滤光片及微透镜(micro-lens)。所述支架设置在所述线路基板上；所述镜片设置在所述支架上；所述指纹芯片设置在所述线路基板上面，且与所述线路基板电性连接；所述滤光片设置在所述指纹芯片上面；所述微透镜设置在所述滤光片上面。由于将微透镜贴付于滤光片表面，滤光片可以设计得较小，降低了成本。
在一些实施例中，所述光学指纹模组40可为其他结构或任意型号，只要所述光学指纹模组40能够进行指纹识别操作即可。
所述机壳20作为承载所述柔性显示面板10的衬底，所述机壳20朝向所述柔性显示面板10的表面开设有透光槽。
为了使所述反射光线能够更好的被光学指纹模组40接收，可设置所述透光槽正对于所述柔性显示面板10的指纹采集区域，由于所述光学指纹模组40收容于所述透光槽远离所述柔性显示面板10的一端，因此所述透光槽可允许更多指纹采集区域的反射光线顺利穿过所述透光槽被所述光学指纹模组40接收，而不被所述机壳20遮挡，从而使所述反射光线能够更好的被光学指纹模组40接收，提高了生成的指纹图像质量，提高解锁速度。
为了更好的将所述透明支撑部30固定于所述机壳20，且位于所述透光槽靠近所述柔性显示面板10的一端，所述透光槽的内侧壁上开设有收容槽22，所述透明支撑部30固定收容于所述收容槽22内，且盖住所述透光槽；同时为了当所述按压物按压所述柔性显示面板10的指纹采集区域时，使所述透明支撑部30更好的对所述指纹采集区域起到支撑作用，消除所述指纹采集区域的形变对指纹成像质量造成的不良影响，将所述透明支撑部30的一表面支撑所述柔性显示面板10，在本实施例中，可将所述透明支撑部30的一表面通过光学胶贴附于所述柔性显示面板10上。
所述光学胶为OCA胶(Optically Clear Adhesive)，所述OCA胶具有无色透明、光透过率在90％以上、胶结强度良好，可在室温或中温下固化，且有固化收缩小等特点。
由于若收容于所述收容槽22内的所述透明支撑部30的厚度过大，则会影响所述柔性显示装置100的外观效果，同时若所述透明支撑部30的厚度过小，则会影响所述透明支撑部30对所述指纹采集区域起到支撑作用，因此需要所述透明支撑部30紧密收容固定于所述收容槽22。
因此为了解决由于透明支撑部30的厚度过大或过小，而带来的上述技术 问题，使所述收容槽22的槽深与所述透明支撑部30的厚度之差不大于预设高度差。优选地，所述预设高度差的范围为10-15um。
目前由于所述机壳20和所述柔性显示面板10之间连接不牢靠，所以当弯折所述柔性显示装置100时，所述机壳20会相对于所述柔性显示面板10产生移动，进而导致所述机壳20与所述柔性显示面板10之间会产生摩擦力，所述摩擦力会对柔性显示面板10造成损伤。
为了消除所述机壳20和所述柔性显示面板10之间的摩擦力，请参阅图2，本申请一些实施例提供的柔性显示装置100a与图1所示的柔性显示装置100基本相同，区别在于所述柔性显示装置100a还包括防磨平坦层50，所述防磨平坦层50设置于所述机壳20和所述柔性显示面板10之间，所述防磨平坦层50用于消除所述机壳20和所述柔性显示面板10之间的摩擦力。
具体地，所述防磨平坦层50包括第一粘附层52、超薄玻璃层54和第二粘附层56；所述超薄玻璃层54设置于所述第一粘附层52和所述第二粘附层56之间，所述超薄玻璃层54的一表面通过所述第一粘附层52贴附于所述柔性显示面板10上，所述超薄玻璃层54的相对的另一表面通过所述第二粘附层56贴附于所述机壳20和所述透明支撑部30上。由于所述超薄玻璃层54一面贴附于所述柔性显示面板10上，所述超薄玻璃层54的另一面贴附于所述机壳20上，因此当弯折所述柔性显示装置100a时，避免了所述机壳20相对于所述柔性显示面板10产生移动，进而减小了所述机壳20和所述柔性显示面板10之间的摩擦力，降低了对所述柔性显示面板10造成的损伤，延长了所述柔性显示面板10的使用寿命。
同时由于所述超薄玻璃层54具有一定的硬度和刚度，所述超薄玻璃层54能够提高所述柔性显示面板10的表面平整度，进而提高了所述柔性显示装置100a的外观美观度。
所述超薄玻璃层54可为含碱超薄玻璃和无碱超薄玻璃，具体地，所述含碱超薄玻璃可为钠钙硅玻璃或铝硅酸盐玻璃。所述无碱超薄玻璃可为硼酸盐 玻璃。
所述超薄玻璃层54经薄化(蚀刻)、强化(离子交换)达到超薄特性的要求，所述超薄玻璃层54的厚度范围可为10μm～100μm，优选地，所述超薄玻璃层54的厚度范围为50μm～75μm。
在一些实施中，为了使所述超薄玻璃层54在可弯折性的基础上，同时可具有较高硬度和/或刚度，以满足耐摔和恢复性特性。所述超薄玻璃层54的表面硬度范围为3H～9H，优选地，所述超薄玻璃层54的表面硬度范围为所4H～7H，所述超薄玻璃层54的杨氏模量(E)范围为10GPa～100GPa，优选地，所述超薄玻璃层54的杨氏模量(E)范围为50Gpa～80Gpa。
所述第一粘附层52和所述第二粘附层56的材质包括环氧化合物、(甲基)丙烯酸酯化合物以及光引发剂，其中环氧化合物包含芳香族环氧化合物和脂环族环氧化合物，且相对于100重量份的环氧化合物和(甲基)丙烯酸酯化合物，芳香族环氧化合物包含10重量份到30重量份的芳香族化合物的多缩水甘油醚。由于所述第一粘附层52和所述第二粘附层56的组成物中包含芳香族化合物的多缩水甘油醚和(甲基)丙烯酸酯化合物，从而使所述第一粘附层52和所述第二粘附层56具有良好耐水性和粘着强度。
在一些实施例中，所述第一粘附层52和所述第二粘附层56可采用任意种类或类型的胶粘剂、粘合剂、粘连剂、胶合剂及粘着剂等等。只需满足所述第一粘附层52和所述第二粘附层56能够分别将所述柔性显示面板10贴附到所述柔性显示面板10和所述机壳20上即可。
为了给所述柔性显示装置提供所需要的外观颜色，请参阅图3，本申请一些实施例提供的柔性显示装置100b与图2所示的柔性显示装置100a基本相同，区别在于所述柔性显示装置100b还包括油墨层60，所述油墨层60层叠于超薄玻璃层54上。具体地，所述油墨层60可涂布于所述超薄玻璃层54的一表面，且/或所述超薄玻璃层54的相对另一表面上。
所述油墨层60的外观颜色可以为红色、橙色、黄色、绿色、青色、蓝色、 紫色、粉色、白色等。油墨层60可以通过喷涂、旋涂、、丝印(丝网印刷，Screen Printing)及其他工艺形成，在本实施例中，所述油墨层60的材料为由环氧树脂调制形成的黑色油墨。
值得注意的是，所述油墨层60的厚度过大或过小，都会对所述柔性显示装置100产生不良影响，例如，油墨层60的厚度过小，无法提供给所述柔性显示装置100所需要的外观颜色；油墨层60的厚度过大，会导致层叠有油墨层的超薄玻璃层区域与未层叠有油墨层的超薄玻璃层区域的断差太大，影响柔性显示面板的表面平整度。
因此为了消除所述油墨层60的厚度过大或过小，而对所述柔性显示装置100b产生的上述不良影响，优选地，所述油墨层60的厚度范围为8～10um。
请一并参阅图4和图5，进一步地，为了避免由于所述油墨层60的遮挡，而导致所述反射光线不能够很好的被所述光学指纹模组40接收，影响生成的指纹图像质量，在所述超薄玻璃层54预留有透光区542和遮光区544，所述透光区542位于所述超薄玻璃层54的中部，所述透光区542之外的所述超薄玻璃层54的其他区域为遮光区544，所述遮光区544围绕所述透光区542。所述油墨层60层叠于所述遮光区544上，所述透光区542正对于所述透光槽，所述超薄玻璃层54上预留的所述透光区542因未涂布有油墨层60，因此所述反射光线可依次穿过所述透光区542和所述透光区542正对的透光空间24，进而被所述光学指纹模组40接收，从而解决了由于所述油墨层60的遮挡，而导致所述反射光线不能够很好的被所述光学指纹模组40接收的技术问题。
本申请另一实施例还提供一种电子设备，所述电子设备包括但不限于手机、笔记本、平板电脑、POS机、车载电脑、相机等。
所述电子设备包括上述任一实施例中的柔性显示装置100、100a、或100b、处理器、收发器、存储器和总线。
其中，所述柔性显示装置100、100a、或100b连接于总线，以通过总线与处理器等其它部分连接。所述柔性显示装置100、100a、或100b的显示区 域可以为操作人员提供一输入界面，以便操作人员通过该输入界面选择布控项。

其中，总线可以是工业标准体系结构(Industry Standard Architecture，ISA)总线、外部设备互连(Peripheral Component，PCI)总线或扩展工业标准体系结构(Extended Industry Standard Architecture，EISA)总线等。该总线可以分为地址总线、数据总线、控制总线等。
与现有技术相比较，本申请电子设备中提供了一种柔性显示装置100、100a、或100b，通过将所述透明支撑部30设置于所述透光槽靠近所述柔性显示面板10的一端，且所述透明支撑部30的一表面支撑所述柔性显示面板10，当所述按压物按压所述柔性显示面板10的指纹采集区域时，由于所述透明支撑部30具有预设硬度和刚度，所述透明支撑部30可在一定程度上抵消掉所述按压物对柔性显示面板10的按压力，对所述指纹采集区域起到支撑作用，消除所述指纹采集区域的形变对指纹成像质量造成的不良影响，提高了指纹成像质量，与用户预存指纹图形匹配度高，进而提高了指纹解锁的准确度和速度。
最后应说明的是：以上实施例仅用以说明本申请的技术方案，而非对其限制；在本申请的思路下，以上实施例或者不同实施例中的技术特征之间也可以进行组合，步骤可以以任意顺序实现，并存在如上所述的本申请的不同方面的许多其它变化，为了简明，它们没有在细节中提供；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围。
