应当理解，本申请说明书以及权利要求书中使用的“第一”“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“一个”或者“一”等类似词语也不表示数量限制，而是表示存在至少一个。除非另行指出，“前部”、“后部”、“下部”和/或“上部”等类似词语只是为了便于说明，而并非限于一个位置或者一种空间定向。“包括”或者“包含”等类似词语意指出现在“包括”或者“包含”前面的元件或者物件涵盖出现在“包括”或者“包含”后面列举的元件或者物件及其等同，并不排除其他元件或者物件。
本申请一个或多个实施例的柔性显示设备可以应用于不同的电子产品的显示系统。不同的电子产品可以包括但不限于手机、个人电脑、键盘、显示器、电视机、车载显示终端、电子书等。本申请实施例的柔性显示设备可以在需要显示时将其屏幕组件展开，在不需要显示时通过卷曲的方式将其屏幕组件收起，以便节约空间。一个示例，本申请实施例的柔性显示设备可以应用于电视机，作为电视机的显示屏。当电视机关机或者不需要显示画面时，电视机的显示屏可以通过卷曲收起以节省空间；当电视机开机或需要显示画面时，电视机的显示屏可以展开为平整的屏幕。又一个示例，本申请实施例的柔性显示设备可以作为单独的显示附件使用，该显示附件，即柔性显示设备可以与各种终端设备(例如：手机、个人电脑等)连接，作为其外接显示设备使用。当终端设备需要进行扩展显示时，柔性显示设备可以连接所述终端设备并将屏幕组件展开进行显示； 当终端设备不需要进行扩展显示时，柔性显示设备可以将其屏幕组件卷曲收起，以方便携带。
如图1所示，在一些实施例中，柔性显示设备100可以包括屏幕组件2和支撑轴6。在一些实施例中，支撑轴6与屏幕组件2的一端1100相连，用于在柔性显示设备100不需要显示时将屏幕组件2进行收卷。在一些实施例中，当柔性显示设备100需要显示时，屏幕组件2可以绕支撑轴6被展开。在一些实施例中，支撑轴6与屏幕组件2的一端1100的连接方式可以是固定连接，也可以是可拆卸连接。在一些实施例中，固定连接的方式可以包括但不限于一体成型、胶粘、销钉连接等。在一些实施例中，可拆卸连接的方式可以包括但不限于卡扣、插拔链接等。

在一些实施例中，柔性显示设备100还可以包括驱动装置，用于驱动支撑轴6进行卷绕操作。在一些实施例中，驱动装置可以包括但不限于弹簧驱动机构、马达驱动机构、棘轮驱动机构、齿轮驱动机构等。在一些实施例中，驱动装置可以设置于收纳装置7内部，以便节约柔性显示设备100的空间大小，并提升柔性显示设备100的整体外观的美观度。在一些实施例中，驱动装置还可以包括设置于收纳装置7内部的用户控制模块，用户控制模块可以采集用户的控制指令并将控制指令传输至驱动装置，用户控制模块可以通过无接触方式来采集用户的控制指令。在一些实施例中，用户控制模块可以是手势识别模块、声控模块等类型。以声控模块为例，驱动装置通过声控模块采集柔性显示设备100的使用者的声控指令，并根据声控指令的内容控制支撑轴6转动，以实现对屏幕组件2的收纳或展开。在一些实施例中，驱动装置也可以是设置于收纳装置7内部的扭力弹簧，当屏幕组件2展开时扭力弹簧发生扭转形变，储存弹性势能，当屏幕组件2需要卷绕时，扭力弹簧可以通过释放弹性势能带动支撑轴6对屏幕组件2进行卷绕。
在一些实施例中，屏幕组件2还可以用于提供触控功能。在一些实施例中，柔性显示设备100的使用者可以在屏幕组件2上通过触控的方式对屏幕组件2显示的画面进行操作。在一些实施例中，屏幕组件2中用于画面显示的显示器件的类型可以包括 但不限于：有机发光二极管(Organic Light Emitting Diode，OLED)、发光二极管(Light Emitting Diode，LED)、微发光二极管(Micro Light Emitting Diode，Micro LED)、次毫米发光二极管(Mini Light Emitting Diode，Mini LED)等。
在一些实施例中，屏幕组件2可以是多层结构。在一些实施例中，屏幕组件2可以包括显示器件层3、阵列结构层4、柔性基底5。其中，各层的顺序从下往上依次为柔性基底5、阵列结构层4、显示器件层3，如图2所示，即显示器件层3可以位于屏幕组件2的最上层，阵列结构层4可以位于显示器件层3与柔性基底5之间，柔性基底5可以位于屏幕组件2的最底层。
在一些实施例中，显示器件层3可以包括发出光线的膜层，例如，显示器件层3可以包括OLED发光层，OLED发光层包括多个呈阵列排布的像素单元，这些像素单元发出光线以使得显示器件层3能够显示画面。在一些实施例中，屏幕组件2还包括触控层，触控层可以设置在显示器件层3的上方用于接收用户触摸操作或保护显示器件层3。在一些实施例中，触控层可以包括触控器件，用于使用户对所述柔性显示设备100进行触摸控制。在一些实施例中，触控层可以包括非接触式感应器件，用于使用户通过相关姿势来对柔性显示设备100的控制。在一些实施例中，触控层可以保护显示器件层3免受撞击损坏的盖板玻璃。
在一些实施例中，阵列结构层4可以用于为显示器件层3提供与显示相关的控制器件。在一些实施例中，阵列结构层4可以包括像素驱动电路，像素驱动电路与显示器件层3电性链接以用于控制显示器件层3的显示画面。在一些实施例中，像素驱动电路可以包括但不限于TFT(Thin Film Transistor)器件和电容器件等。
在一些实施例中，柔性基底5可以是屏幕组件2的基材膜层，用于支撑显示器件层3和阵列结构层4。在一些实施例中，柔性基底5的材料可以包括但不限于聚酰亚胺(Polyimide，PI)材料、聚对苯二甲酸乙二醇酯(Polyethylene terephthalate，PET)材料、聚苯并咪唑(Polybenzimidazoles，PBI)材料、聚醚醚酮(Polyetheretherketone，PEEK)材料、聚偏氟乙烯(Polyvinylidene fluoride，PVDF)材料、聚醚类塑料(Polyphenylenesulphide，PPS)材料，以及上述材料的任意组合；在另外的实施例中，柔性基底5还可以是具有弯曲性能的玻璃材料，仅需保证玻璃厚度符合弯折需求即可。在一些实施例中，在柔性基底层5的若干组合材料中，聚酰亚胺的质量占比为50％～100％；在一些实施例中，在柔性基底层5的若干组合材料中，聚酰亚胺的质量占比为60％～90％。在一些实施例中，聚对苯二甲酸乙二醇酯的质量占比为0～20％；在一些实施例中，聚对 苯二甲酸乙二醇酯的质量占比为0～10％；在一些实施例中，聚对苯二甲酸乙二醇酯的质量占比为0～4％。在一些实施例中，聚苯并咪唑的质量占比为0～30％；在一些实施例中，聚苯并咪唑的质量占比为5～20％；在一些实施例中，聚醚醚酮的质量占比为0～4％。在一些实施例中，聚偏氟乙烯的质量占比为0～10％；在一些实施例中，聚偏氟乙烯的质量占比为0～5％。在一些实施例中，聚醚类塑料的质量占比为0～10％；在一些实施例中，聚醚类塑料的质量占比为0～5％。
在一些实施例中，屏幕组件2还可以包括缓冲层。在一些实施例中，缓冲层可以用于当屏幕组件2受到冲击时起缓冲作用。在一些实施例中，缓冲层可以设置在柔性基底5的下方，并位于柔性基底5和支撑结构之间。在一些实施例中，缓冲层的材料可以包括但不限于泡棉类材料，例如聚氨基甲酸酯(Polyurethane，PU)泡棉，硅泡棉，亚克力泡棉。
在一些实施例中，由于屏幕组件2具备可卷曲的性能，当屏幕组件2处于展开状态时，屏幕组件2的表面受到力的作用可能无法保持平坦，从而影响屏幕组件2的显示效果。本申请实施例的屏幕组件2在具有不同刚度需求的方向能够获得不同的刚度。在沿其卷曲方向的第一方向，屏幕组件2可以获得较低的刚度，使得屏幕组件2容易卷曲收纳；在垂直于其卷曲方向的第二方向，屏幕组件2可以获得较高的刚度，使得整个屏幕组件2不易因外力的作用发生变形，进而保证屏幕组件2的显示效果。
本申请一些实施例的屏幕组件2的背面可以设置支撑结构，支撑结构能够带来第一方向的较低的刚性和第二方向较高的刚性，使屏幕组件2既具备易卷曲的性能，又能保证其展开时的平整性。以下结合附图详细描述该结构。
应当理解的是，本说明书的一个或多个实施例的系统及方法的应用场景仅仅是本说明书的一个或多个实施例的一些示例，对于本领域的普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图将本说明书的一个或多个实施例应用于其它类似情景。例如，其他类似的显示系统。
在一些实施例中，如图3A～3C所示，柔性显示设备200可以包括屏幕组件2和支撑结构20。支撑结构20设置在屏幕组件2上，用于支撑屏幕组件2。在一些实施例中，所述支撑结构20可以设置在屏幕组件2的背面。其中，所述屏幕组件2的背面可以理解为背离屏幕组件2出光面的那一面。
在一些实施例中，支撑结构20可以设置在屏幕组件2中最下面一层的背面，例如，支撑结构20可以设置在柔性基底5的背面上。在一些实施例中，支撑结构20也可 以设置在屏幕组件2内部，即可以将支撑结构设置在屏幕组件2中最下面一层的正面与最上面一层的背面之间的任一位置。例如，支撑结构20可以设置在柔性基底5和阵列结构层4之间。其中，对于屏幕组件2中的若干膜层来说，朝向屏幕组件2出光面的那一面为正面，背离屏幕组件2出光面的那一面为背面。在一些实施例中，支撑结构20可以用于在展开状态下对屏幕组件2进行支撑。在一些实施例中，支撑结构20可以与屏幕组件2连接。在一些实施例中，支撑结构20与屏幕组件2的连接方式可以包括但不限于胶粘、静电吸附、磁性吸附等。在一些实施例中，支撑结构20与屏幕组件2具有不同的材料。在一些实施例中，支撑结构20的材料可以包括钢，钛合金，铝合金，玻璃，碳纤维，玻璃纤维。在另一些实施例中，支撑结构20的材料除了包括钢，钛合金，铝合金，玻璃，碳纤维，玻璃纤维之外，还可以包括硅胶、橡胶、水凝胶。在一些实施例中，支撑结构20的材料可以是均一的，也可以包括两种或以上材料。在一些实施例中，支撑结构20与屏幕组件2也可以具有相同的材料。
在一些实施例中，柔性显示设备200还可以包括电源接口30。在一些实施例中，电源接口30可以用于连接向柔性显示设备200提供工作所需电力的电源。在一些实施例中，柔性显示设备200可以不具有电源接口30，而是通过内置的电池为柔性显示设备200提供电源。
在一些实施例中，柔性显示设备200还可以包括信号接口40。在一些实施例中，信号接口40可以用于将柔性显示设备200与信号源连接。在一些实施例中，所述信号源可以是任意类型的能够进行影像数据输出的终端设备，包括但不限于手机、平板电脑、个人电脑、电视机、游戏机等。在一些实施例中，信号接口40可以是有线接口。在一些实施例中，有线接口可以包括但不限于交互式数字视频系统(Digital Visual Interface，DVI)接口、高清晰度多媒体(High Definition Multimedia Interface，HDMI)接口、模拟接口(D-subminiature，D-sub)、视频图形阵列(Video Graphics Array，VGA)接口、数据处理(Data Processing，DP)接口、通用串行总线(Universal Serial Bus，USB)接口等。在一些实施例中，信号接口40也可以是无线接口。在一些实施例中，无线接口可以是任意类型的无线网络接口，包括但不限于区域网络(Local Area Network，LAN)接口、广域网络(Wide Area Network，WAN)接口、无线区域网络(Wireless Local Area Network，WLAN)接口、都会区域网络(Metropolitan Area Network，MAN)接口、蓝牙网络接口、紫峰(ZigBee)无线网络接口、近场通讯(Near-field Communication，NFC)网络接口等。
在一些实施例中，电源接口30和信号接口40也可以一体实现，即柔性显示设备200可以提供一个接口，该接口可以在将柔性显示设备200与信号源连接的同时，为柔性显示设备提供电源连接。需要注意的是，柔性显示设备200也可以没有电源接口30和信号接口40，其不会影响柔性显示设备200的显示性能及支撑性能，本申请对此不作限定。
在一些实施例中，柔性显示设备200的屏幕组件2可以在需要显示时展开(如图3A、3B所示)，在不需要显示时通过卷曲的方式收起(如图3C所示)。在一些实施例中，屏幕组件2卷曲时，可以沿卷曲方向，从屏幕组件2的两端开始卷曲；也可以从屏幕组件2的其中一端开始卷曲。在一些实施例中，所述屏幕组件2的卷曲方向是指屏幕组件2从开始卷曲的一端向另一端进行卷动的方向。在一些实施例中，参照图3A所示，屏幕组件2的卷曲方向可以是第一方向1001，与卷曲方向垂直的方向可以是第二方向1002。
在一些实施例中，参见图4A、4B，柔性显示设备200可以为单轴卷曲形式，此时，柔性显示设备200还可以包括一个支撑轴6，支撑轴6沿第二方向1002固定于屏幕组件2垂直于第一方向1001的任意一个端部侧边。其中，所述支撑轴6设置在所述屏幕组件2的一端。在一些实施例中，所述支撑轴6的轴线平行于所述第二方向，以使所述屏幕组件2能够沿所述第一方向围绕所述支撑轴6卷曲。在一些实施例中，在屏幕组件2展开时，所述支撑轴6可以用于沿第二方向1002支撑屏幕组件2。在一些实施例中，在屏幕组件2卷曲时，所述支撑轴6可以作为卷曲的中心轴，支撑卷曲后的屏幕组件2。本实施例的柔性显示设备200在屏幕组件2展开时，支撑轴6可以对屏幕组件2进行支撑，提高屏幕组件2保持平坦的能力；在屏幕组件2卷曲时，支撑轴6可以使屏幕组件2更容易卷曲，并且卷曲后所占用的空间较小。
在一些实施例中，参见图5A、5B，柔性显示设备200也可以为双轴卷曲形式，此时，柔性显示设备200可以包括两个支撑轴6，所述两个支撑轴6沿第二方向1002分别固定于屏幕组件2垂直于第一方向1001的两个相对的侧边。其中，两个支撑轴6的轴线都平行于所述第二方向，以使所述屏幕组件2沿所述第一方向分别围绕所述两个支撑轴6进行卷曲。在一些实施例中，屏幕组件2卷曲时，两个支撑轴6的转动方向相反，即在屏幕组件2卷曲的过程中，两个支撑轴6分别沿第一方向相对转动，最后转至相互接触的位置，如图5B所示。在一些实施例中，在屏幕组件2展开时，所述两个支撑轴6可以用于沿第二方向1002分别支撑屏幕组件2的两侧。在一些实施例中，在屏 幕组件2卷曲时，两个支撑轴6沿着相反的旋转方向转动，两个支撑轴6可以分别作为卷曲时的支撑轴，将屏幕组件2的屏幕组件2和支撑结构20卷绕在支撑轴6的外表面上，如图5B所示。在一些实施例中，屏幕组件2卷曲时，两个支撑轴6的转动方向相反(例如，其中一个支撑轴6顺时针转动，另一个支撑轴6逆时针转动)，并且在屏幕组件2卷曲的过程中，两个支撑轴6分别沿第一方向相向移动，最后转至相互接触的位置，形成如图5B所示的“双筒望远镜”的形状。在一些实施例中，屏幕组件2卷曲时，两个支撑轴6的转动方向相同(例如，两个支撑轴6都顺时针转动，或者两个支撑轴6都逆时针转动)，并且在屏幕组件2卷曲的过程中，两个支撑轴6分别沿第一方向相向移动，最后转至相互接触的位置，形成“8”字形状。本实施例的柔性显示设备200在屏幕组件2展开时，支撑轴6可以从两侧对屏幕组件2进行支撑，其支撑能力更强，屏幕组件2更易保持平坦；在卷曲时，支撑轴6也可以起到辅助卷曲的作用。
在一些实施例中，柔性显示设备200也可以没有支撑轴6，屏幕组件2卷曲时，可以通过手动辅助的方式，直接将屏幕组件2卷起，屏幕组件2自身卷绕起来，不再卷绕在支撑轴6上。此时，屏幕组件2可以从任意一端向另一端卷起，也可以从两端向中间卷起。
在一些实施例中，如图4A、4B所示，柔性显示设备200还可以包括收纳装置7。在一些实施例中，收纳装置7可以用于在屏幕组件2卷曲时对屏幕组件2进行收纳，保护其免受外物的损伤或污染。在一些实施例中，支撑轴6可以设置于收纳装置7内部。在一些实施例中，收纳装置7可以沿第二方向1002设置于屏幕组件2垂直于第一方向1001的任意一个端部侧边处。在一些实施例中，收纳装置7的个数可以与支撑轴6的个数相同。例如，柔性显示设备200为单轴卷曲形式，收纳装置7可以是一个，设置在所述屏幕组件2的其中一端。又例如，柔性显示设备200为双轴卷曲形式，收纳装置7可以是两个，分别设置在所述屏幕组件2的两端。
在一些实施例中，若柔性显示设备200为单轴卷曲形式，参见图4A，支撑轴6可以不始终收纳于收纳装置7内，收纳装置7与支撑轴6可以分别设置在屏幕组件2的相对两侧边。在一些实施例中，当屏幕组件2展开时，收纳装置7位于与支撑轴6相对的一侧，收纳装置7和支撑轴6可以从屏幕组件2的两个侧边支撑屏幕组件2。进一步参见图4B，在一些实施例中，当屏幕组件2卷曲时，屏幕组件2可以卷绕在支撑轴6上，收纳装置7可以对卷绕了屏幕组件2的支撑轴6进行收纳。
在一些实施例中，柔性显示设备200在需要使用时可以自动将屏幕组件2展开， 不需要使用时可以自动将屏幕组件2卷曲收起，为实现柔性显示设备200的自动化动作，柔性显示设备200还可以包括一个或多个驱动装置，以带动支撑轴6旋转，以实现自动地展开或自动地卷曲收起。
在一些实施例中，驱动装置可以包括第一驱动装置，所述第一驱动装置可以设置于收纳装置7内部(图中未示出)。在一些实施例中，第一驱动装置可以驱动支撑轴6进行第一旋转，以将所述屏幕组件2进行卷曲收纳，即将屏幕组件2卷绕在支撑轴6的表面。在一些实施例中，所述第一旋转可以是绕支撑轴6的中心轴的旋转。在一些实施例中，所述第一旋转可以是顺时针方向的旋转，也可以是逆时针方向的旋转。在一些实施例中，第一驱动装置可以包括但不限于弹簧驱动机构、马达驱动机构、棘轮驱动机构、齿轮驱动机构等。具体的，在一些实施例中，屏幕组件2可以通过手动的方式进行展开，例如，柔性显示设备的操作者可以从屏幕组件2的一端开始拉拽，将屏幕组件2从支撑轴6上展开。当柔性显示设备的屏幕组件2需要卷曲时，第一驱动装置可以驱动支撑轴6进行第一旋转，将展开的屏幕组件2重新卷绕在支撑轴6上。例如，第一驱动装置可以是固定在支撑轴6上的弹簧驱动机构，屏幕组件2在展开的过程中可以带动支撑轴6旋转并使弹簧驱动机构积蓄弹性势能，当展开屏幕组件2的拉拽力消失后，弹簧驱动机构可以释放弹性势能从而驱动支撑轴6旋转。又例如，第一驱动装可以是单向旋转的电机驱动机构，当屏幕组件2被手动展开后，可以通过单向旋转的电机驱动机构驱动支撑轴6进行第一旋转，将屏幕组件2卷绕在支撑轴6上。

在一些实施例中，当屏幕组件2展开时，进一步参见图6，支撑件210可以从屏幕组件2背面的多个位置对屏幕组件2进行支撑，从而改变柔性显示设备在第一方向 1001和第二方向1002的刚度。
在一些实施例中，当屏幕组件2卷曲时，进一步参见图7，由于支撑件210间隔分布于屏幕组件2的背面，各支撑件210之间的间隙使得支撑件210可以随屏幕组件2一同卷绕进行收纳。在一些实施例中，屏幕组件2卷绕后，屏幕组件2还可以被支撑件210隔开，减少屏幕组件2在卷绕时可能产生的摩擦。
在一些实施例中，支撑件210沿第一方向的尺寸以及与该支撑件相邻的间隙沿第一方向1001的长度的比值可以为1:10～1:1中的任一数值；在一些实施例中，所述比值可以是1:8～1:1中任一数值；在一些实施例中，所述比值可以是1:6～1:2中任一数值；在一些实施例中，所述比值可以是1:5～1:4中任一数值。在一些实施例中，所述比值从靠近支撑轴6的区域以1:1的数值向远离支撑轴6的区域逐渐地变化至1:10。其中，当柔性显示设备为单轴卷曲形式时，所述远离支撑轴的区域可以是屏幕组件上远离支撑轴的那个侧端；当柔性显示设备为双轴卷曲形式时，所述远离支撑轴的区域也可以是屏幕组件沿第一方向的中间区域。在一些实施例中，所述比值从靠近支撑轴6的区域以1:1的数值向屏幕组件2的中间区域逐渐地变化至1:10，然后再从1:10继续向远离支撑轴6的区域逐渐地变化至1:1。在一些实施例中，所述比值从靠近支撑轴6的区域以1:1的数值向屏幕组件2的中间区域逐渐地变化至1:5，然后再从1:5继续向远离支撑轴6的区域逐渐地变化至1:10。
在一些实施例中，支撑件210可以沿所述第一方向1001相对屏幕组件2的不同位置进行分布，以使柔性显示设备沿第一方向1001的刚度不同。在一些实施例中，参见图9～12，屏幕组件2可以包括沿第一方向1001分布的第一区域810和第二区域820。在一些实施例中，第一区域810沿所述第一方向1001的刚度需求大于所述第二区域820沿所述第一方向1001的刚度需求。
在一些实施例中，屏幕组件2在进行卷曲收纳的过程中，越靠近柔性显示设备200的支撑轴6的区域，卷曲半径越小，卷曲幅度越大，越容易反弹。因此，在靠近支撑轴6的区域柔性显示设备的刚度较小，远离支撑轴6的区域柔性显示设备的刚度较大，即第一区域810可以是沿第一方向远离支撑轴6的区域，第二区域820可以是靠近支撑轴6的区域。
在一些实施例中，若柔性显示设备200为单轴卷曲形式，参见图9～11，则第一区域810可以位于远离支撑轴6的一侧，第二区域820可以位于靠近支撑轴6的一侧。对应地，在一些实施例中，第一区域810沿第一方向1001的宽度与屏幕组件2沿第一 方向1001的宽度的比值可以是0.2～0.8；优选的，可以是0.3～0.7；进一步优选的，可以是0.4～0.6。在一些实施例中，第二区域820沿第一方向1001的宽度与屏幕组件2沿第一方向1001的宽度的比值可以是0.2～0.8；优选的，可以是0.3～0.7；进一步优选的，可以是0.4～0.6。在一些实施例中，若柔性显示设备200为双轴卷曲形式，则第一区域810可以位于屏幕组件2的中间区域，第二区域820可以位于屏幕组件2的两侧区域。在一些实施例中，第一区域810沿第一方向1001的宽度与屏幕组件2沿第一方向1001的宽度的比值可以是0.2～0.6；优选的，可以是0.2～0.4；进一步优选的，可以是0.3～0.4。在一些实施例中，第二区域820沿第一方向1001的宽度可以是0.2～0.4；优选的，可以是0.3～0.4；进一步优选的，可以是0.3～0.35。
在一些实施例中，支撑件210对应于第一区域810的密度分布可以是第一密度分布，对应于第二区域820的密度分布可以是第二密度分布。其中，所述第一密度分布大于所述第二密度分布。
在一些实施例中，所述第一密度分布可以是均匀分布。在一些实施例中，所述第一密度分布也可以是渐变分布。在一些实施例中，所述第二密度分布可以是均匀分布。在一些实施例中，所述第二密度分布也可以是渐变分布。
其中，所述第一密度分布和第二分配密度可以通过支撑件沿第一方向的尺寸以及与该支撑件相邻的间隙沿第一方向的尺寸的比值来反映。为了方便描述，第一区域内，支撑件210沿第一方向的尺寸与其相邻的间隙沿第一方向的尺寸比值称为第一比值；第二区域内，支撑件210沿第一方向的尺寸与其相邻的间隙沿第一方向的尺寸比值称为第二比值。

在一些实施例中，参见图8～9，第二部分222以凸条或凹槽状态形成在支撑膜220上,第二部分222的形态支撑膜220并能够被人眼、显微镜等检测设备观察到，以使得第二部分222的宽度和厚度等参数可以明确的检测出。在一些实施例中，以第二部分222是凸条状为例，这种凸条状的第二部分222可以与支撑膜220分离的，例如可以通过在支撑膜220上喷涂，胶粘，热压成型、物理蒸镀或溅镀方式等方式这类第二部分。在一些实施例中，以第二部分222是凹槽状为例，这种凹槽状的第二部分222可以通过刻蚀等方式形成，值得注意的是，此时需要对凹槽内掺杂更多量的第二材料，以保证第二部分222刚性超过第一部分的刚性。
在一些实施例中，第二部分222还可以与第一部分221形成不同的色差、纹理，第一部分和第二部分仍然可以被人眼、显微镜等检测设备观察到，第二部分222的宽度和厚度等参数也可以明确的检测出。在一些实施例中，以第二部分222和第一部分221存在纹理差异为例，可以通过在支撑膜不同区域掺杂对应材料形成第一部分和第二部分，并对应位置上方进行纹理处理，以作区分。在一些实施例中，以第二部分222是凸条状为例，从俯视或仰视屏幕组件2的方向上，凸条的形状可以包括矩形或腰形或梯形。在一些实施例中，第二部分222的形状是矩形。在一些实施例中，矩形的宽度尺寸为10mm-300mm；优选的，尺寸为10mm-200mm；优选的，尺寸为10mm-150mm；优选的，尺寸为10mm-100mm；优选的，尺寸为10mm-50mm；进一步优选的，尺寸为10-20mm。在一些实施例中，矩形的长度与屏幕组件2边缘沿第二方向1002的尺寸比例可以是0.8～1.1；优选的，可以是0.97；进一步优选的，可以是0.98。在一些实施例中，腰形的直径可以是10mm-300mm；优选的，尺寸为10mm-200mm；优选的，尺寸为10mm-150mm； 优选的，尺寸为10mm-100mm；优选的，尺寸为10mm-50mm；进一步优选的，尺寸为10-20mm。腰形的直边长度与屏幕组件2边缘沿第二方向1002的尺寸比例可以是0.8～1.1；优选的，可以是0.97；进一步优选的，可以是0.98。应当注意的是，凸条状第二部分的形状也可以参考本说明书中支撑件210的形状设置。
在一些实施例中，当屏幕组件2展开时，支撑膜220可以在屏幕组件2的背面对屏幕组件2进行支撑。在一些实施例中，当屏幕组件2卷曲时，支撑膜220可以位于屏幕组件2的各卷绕层之间。
在一些实施例中，第二部分222可以沿所述第一方向1001相对屏幕组件2的不同位置进行分布，以使柔性显示设备沿第一方向1001的刚度不同。
在一些实施例中，柔性显示设备200可以是单轴卷曲形式，第二部分222密度分布与渐变规则可以参考图11中支撑件210的相关描述。

在一些实施例中，屏幕组件2从卷曲状态展开时，需要恢复至平整状态，以便于屏幕组件2进行画面显示。在一些实施例中，由于靠近柔性显示设备200的支撑轴6的区域在卷绕过程中，卷曲变形更大，其恢复平整所需的弹性力更大。因此，若该区域柔性显示设备具有更大的刚度，则可以有利于该区域恢复平整。因此，在一些实施例中，参见图13～14，所述第二区域820可以是靠近支撑轴的区域，第一区域810可以是远离支撑轴的区域。其中，第一区域810和第二区域820对应的支撑件210或第二部分222的密度分布可以参考图9～10中的分布规则设置。
在一些实施例中，支撑结构20包括具有若干图形孔2301的第二支撑膜，即支撑膜230。在一些实施例中，图形孔2301可以减小支撑膜230上对应区域的刚度，即支撑膜230中，存在图形孔2301的区域的刚度比不存在图形孔2301的区域的刚度更小。在一些实施例中，所述第二支撑膜可以是设置在屏幕组件2中最下面一层背面的膜层；在一些实施例中，也可以是屏幕组件2中任一个可实施若干图形孔方案的膜层。

在一些实施例中，图形列2302可以沿所述第一方向1001以不同的分布密度进行设置，以使柔性显示设备沿第一方向1001的刚度不同。在一些实施例中，图形列的分布密度可以通过图形列2302在对应区域的开孔率来反映。在一些实施例中，所述图 形列2302所对应区域的开孔率可以是0.2～0.8；优选的，可以是0.4～0.8；进一步优选的，可以是0.6～0.8。所述开孔率可以理解为在支撑膜230的规定面积内，开设图形孔的面积与所述规定面积的比值。在一些实施例中，所述规定面积可以是支撑膜230的整体面积。在一些实施例中，所述规定面积也可以是支撑膜230的局部面积。例如，所述局部面积可以是一个沿第二方向分布的图形列加上与该图形列相邻的间隙的面积。例如，所述局部面积可以是下文中的第一区域或第二区域。

在一些实施例中，图形列2302在第一区域和第二区域内沿第一方向的不同位置处，开孔率可以均匀地设置，也可以渐变地设置。
在一些实施例中，支撑结构中的支撑膜230上也可以包括若干第二部分222以及图形列2302。参照图17所示，支撑结构包括若干个图形列2302，3个图形列2302形成一个阵列组，相邻两个阵列组之间设有支撑子部件2221。
在一些实施例中，柔性显示设备200的支撑轴6的横截面可以是圆形，也可以是方形。在一些实施例中，若柔性显示设备200的支撑轴6的横截面是圆形的，则支撑结构20可以是上述任意一个实施例所述的支撑结构。
在一些实施例中，若柔性显示设备200的支撑轴6的横截面是方形的，则支撑结构20的结构可以进一步参见图17以及图18。

在一些实施例中，支撑结构20也可以只包括间隔分布设置的支撑件210，当屏幕组件2卷曲时，支撑件210可以对应于支撑轴6的侧边，支撑轴6的棱边可以对应于相邻两个支撑件210的间隙。

在一些实施例中，当支撑结构20包括若干支撑件或若干第二部分时，则屏幕组件2卷曲后，支撑轴6的倒角区域可以与支撑件或第二部分的间隔空隙对应。对应的，在展开状态下，支撑件或第二部分的间隔空隙大于对应位置的倒角的弧长。
