随着显示技术的发展，用户对显示设备的显示面积的要求越来越高，在使用状态下，显示面积越大越好，折叠屏和滑移屏由折叠到展开最多只能增加约50％-60％的屏幕面积，为进一步增大显示面积，开发了卷曲式终端。发明人经研究发现，卷曲式终端中，柔性显示面板展开后容易发生翘曲，从而使得柔性显示面板的平整性较差，影响用户体验。基于对上述问题的研究，发明人提供了一种柔性显示装置和移动终端，以提升柔性显示面板展开后的平整性。
为了更好地理解本申请，下面结合图1至图12根据本申请实施例的柔性显示装置和移动终端进行 详细描述。
请参阅图1和图2，本申请实施例提供了一种卷曲组件1，包括卷轴11、安装件12和支撑件13。卷轴11用于固定柔性显示面板10的第一端且收卷柔性显示面板10。安装件12用于固定柔性显示面板10的第二端。支撑件13具有收纳工位和展开工位。当柔性显示面板10处于展开状态时，支撑件13处于展开工位，支撑件13设置于柔性显示面板10背离显示面的一侧，支撑件13用于为柔性显示面板10提供支撑。当柔性显示面板10处于收纳状态时，支撑件13处于收纳工位。
本申请提供的卷曲组件1中，包括卷轴11、安装件12和支撑件13。在使用过程中，柔性显示面板10的第一端101与卷轴11固定、第二端102固定于安装件12，当柔性显示面板10卷绕于卷轴11时，柔性显示面板10处于收纳状态，支撑件13处于收纳工位，而当柔性显示面板10处于展开状态时，支撑件13处于展开工位，柔性显示面板10背离出光面的一侧设置有支撑件13，以由柔性显示面板10背离出光面的一侧的支撑件13为柔性显示面板10提供支撑，从而提升了柔性显示面板10处于展开状态时的平整度，提升了用户体验。
在一种可行的实施方式中，卷曲组件1为单向卷绕的卷曲组件，即柔性显示面板10仅第一端101为固定于卷轴11的卷曲端，柔性显示面板10可卷绕于卷轴11，柔性显示面板10的第二端102为可拉伸端，拉动可拉伸端可使得柔性显示面板10处于展开状态，安装件12包括用于夹紧第二端102的夹紧件122。
在上述实施方式中，当安装件12与卷轴11之间的距离增大时，可使得柔性显示面板10逐渐处于展开状态，从而使得柔性显示面板10中的可视显示面积逐渐增大。当安装件12与卷轴11之间的距离减小时，可使得柔性显示面板10逐渐卷绕于卷轴11以至收纳状态，从而使得柔性显示面板10中的可视显示面积逐渐减小，同时便携性提升。
在一种可行的实施方式中，如图3所示，卷曲组件1为双向卷绕的卷曲组件，柔性显示面板10的第一端101和第二端102均为卷曲端，安装件12包括卷绕轴120，柔性显示面板10部分卷绕于卷绕轴120。
在上述实施方式中，柔性显示面板10中靠近第一端101的部分可卷绕于卷轴11、靠近第二端102的部分可卷绕于卷绕轴120，从而使得柔性显示面板10处于收纳状态时部分卷绕于卷轴11、部分卷绕于卷绕轴120。当卷绕轴120与卷轴11之间的距离增大时，可使得柔性显示面板10逐渐处于展开状态，从而使得柔性显示面板10的可视显示面积逐渐增大。当卷绕轴120与卷轴11之间的距离减小时，可使得柔性显示面板10部分逐渐卷绕于卷轴11、部分卷绕于卷绕轴120以至收纳状态，从而使得柔性显示面板10的可视显示面积逐渐减小，同时便携性提升。
在一种可行的实施方式中，柔性显示面板10逐渐卷绕于卷轴11和/或卷绕轴120的方式包括：
手动使得卷轴11和/或卷绕轴120转动，以使得柔性显示面板10逐渐卷绕于卷轴11和/或卷绕轴120。
或者，卷曲组件1还包括驱动装置(图中未示出)，驱动装置与卷轴11和/或卷绕轴120连接，并用于驱动卷轴11和/或卷绕轴120转动，以使得柔性显示面板10逐渐卷绕于卷轴11和/或卷绕轴120，驱动装置可包括电机等，本申请不做特别限定。
或者，如图4所示，卷曲组件1还包括卷簧16，卷簧16设置于柔性显示面板10背离出光面的一侧，卷簧16与柔性显示面板10之间固定连接，卷簧16包括卷曲端和自由端，当卷曲组件1为单向卷绕显示装置时，卷曲组件1中可包括一个卷簧16，卷簧16的卷曲端位于靠近柔性显示面板10第一端101的一侧，自由端位于靠近柔性显示面板10的第二端102的一侧。当拉伸柔性显示面板10的第二端102时，克服卷簧16的收缩力，以使卷簧16处于展开状态，当停止对柔性显示面板10的第二端102的拉伸时，卷簧16恢复自然状态，即卷簧16卷绕于卷轴11以处于卷曲的状态，从而使得柔性显示面板10由展开状态恢复收纳状态。卷簧16贴合在柔性显示面板10背离出光面的一侧，起到使屏体收缩和展开的作用，并支撑屏体。
如图5所示，当卷曲组件1为双向卷绕的卷曲组件时，卷曲组件1中可包括两个卷簧，如第一卷簧161和第二卷簧162，第一卷簧161和第二卷簧162沿平行于由卷轴11指向安装件12的方向排列，其中，由卷轴11指向安装件12的方向为第二方向X，第一卷簧161的卷曲端位于靠近柔性显示面板10第一端101的一侧，第一卷簧161的自由端与第二卷簧162的自由端固定，第二卷簧162的卷曲端位于靠近柔性显示面板10的第二端102的一侧。当卷轴11与卷绕轴120之间的距离增大时，克服第一卷簧161和第二卷簧162的收缩力，第一卷簧161和第二卷簧162均处于展开状态，当卷轴11与卷绕轴120之间的距离减小时，第一卷簧161和第二卷簧162均逐渐恢复自然状态，即第一卷簧161卷绕于卷轴11以处于卷曲的状态、第二卷簧162卷绕于卷绕轴120以处于卷曲状态，从而使得柔性显示面板10由展开状态恢复收纳状态。其中，卷簧16可对柔性显示面板10起到辅助支撑的作用，使得柔性显示面板10展开后更为平 整。
可以理解的是，能够使得柔性显示面板10逐渐卷绕于卷轴11和/或卷绕轴120的方式不限于以上方式，本申请不做特别限定。
在一种可行的实施方式中，卷曲组件1还包括磁吸件17，磁吸件17设置于支撑件13和/或卷簧16，用于将支撑件13和卷簧16吸附固定。
在上述实施方式中，当柔性显示面板10处于展开状态时，卷簧16随柔性显示面板10同步处于展开状态，支撑件13处于展开工位并与卷簧16接触、以对柔性显示面板10提供支撑，通过在卷簧16和/或支撑件13上设置磁吸件17，以在柔性显示面板10处于展开状态时，通过卷簧16与支撑件13之间的磁吸附力吸附固定，以使得卷簧16与支撑件13贴附更为紧密，从而使得支撑件13对柔性显示面板10的支撑效果更好，使得柔性显示面板10的平整度更高。
具体地，如图5所示，磁吸件17可包括磁粉，当卷簧16和支撑件13均采用可被磁吸件17吸附的磁性材料制备而成时，可在卷簧16和支撑件13内设置磁粉，以将卷簧16和支撑件13吸附固定。
磁吸件17还可以包括设置于支撑件13的电磁铁，当电磁铁通电时具有磁性，可对卷簧16进行吸附，以提升柔性显示面板10处于展开状态时的平整性。同时也可防止柔性显示面板10处于展开状态后卷簧16回弹，保持柔性显示面板10的可视显示面积的大小。当电磁铁断电时磁性消失，对卷簧16的吸附力消失，以避免对需要进行收纳时产生阻力，不利于柔性显示面板10进行卷绕的情况发生。
在一种可行的实施方式中，如图5所示，支撑件13包括第一支撑件131，第一支撑件131包括多个支撑板，当第一支撑件131处于展开工位时，多个支撑板沿平行于由卷轴11指向安装件12的方向依次排列，即多个支撑板沿平行于第二方向X的方向依次排列，且相邻支撑板之间通过转动件133可翻转连接。
在上述实施方式中，当第一支撑件13处于展开工位时，多个支撑板朝向柔性显示面板10的一侧表面均位于同一平面上，以提升柔性显示面板10的平整度。支撑板的个数为至少两个。
在上述实施方式中，转动件133可以为具有弹性的连接片等，本申请不做特别限定。
在一种可行的实施方式中，当第一支撑件13处于收纳工位时，至少部分支撑板沿第一方向Z排列(即层叠设置)，其中，第一方向Z垂直于由卷轴11指向安装件12的方向X。第一方向Z可垂直于第二方向X。部分或全部支撑板沿第一方向Z排列，可以减小收纳后的体积。第一方向Z可垂直于处于展开状态时的柔性显示面板的显示面。
在一种可行的实施方式中，如图5所示，第一支撑件131与卷轴11、安装件12中的一者连接。此时，第一支撑件131包括未与卷轴11以及安装件12连接的自由端A，可通过拉动自由端A以使得第一支撑件131处于展开工位。
在另一种可行的实施方式中，第一支撑件131沿自身展开方向(平行于第二方向X)的两端分别与卷轴11、安装件12中的一者和另一者连接。
当第一支撑件131处于展开工位时，除位于两端的支撑板外，其余支撑板的沿第二方向X相对的两端分别与两侧邻近的支撑板连接。位于端部的支撑板的沿第二方向X相对的两端中的一端与邻近的支撑板连接，另一端与卷轴11或安装件12连接。
其中，第一支撑件131沿自身展开方向(平行于第二方向X)的两端中的一端与卷轴11、安装件12中的一者连接可以是固定连接，还可以是翻转连接和/或沿第一方向Z滑动连接。翻转连接可为转动连接。第一支撑件131沿自身展开方向(平行于第二方向X)的两端中的另一端与卷轴11、安装件12中的另一者连接可以是固定连接，还可以是翻转连接和/或沿第一方向Z滑动连接。

在上述实施方式中，可选的，第一支撑件131与卷轴11或安装件12滑动连接的一端设置有凸起(相当于滑块的作用)，凸起在卷轴11或安装件12上设置的沿第一方向Z延伸的滑槽内可滑动和转动，以实现第一支撑件131与卷轴11或安装件12之间可滑动转动连接，从而使得第一支撑件131的展开和收纳过程更为顺畅。可根据需要设置滑槽和凸起的形状和间隙，以保证滑动和转动的顺畅度。

具体地，多个第一支撑板1311中，最远离第三支撑板1313的第一支撑板1311远离第二支撑板1312的一端与第一连接件的一端转动连接，第一连接件的另一端与卷轴11滑动连接。多个第二支撑板1312中，最远离第三支撑板1313的第二支撑板1312远离第一支撑板1311的一端与第二连接件的一端转动连接，第二连接件的另一端与安装件12滑动连接。增设有上述第一连接件和第二连接件，从而可提升第一支撑件131展开时的顺畅度。
如图10所示，当第一支撑件131处于收纳工位时，与卷轴11滑动连接的第一支撑板1311、与安装件12滑动连接的第二支撑板1312均位于第三支撑板1313远离柔性显示面板的一侧，其中，多个第一支撑板1311沿第一方向Z排列，多个第二支撑板1312沿第一方向Z排列，第一支撑板1311和第二支撑板1312沿第二方向X排列。第三支撑板1313可与柔性显示面板10或卷簧16固定连接，当第一支撑件131由收纳工位向展开工位切换时，第一支撑板1311、第二支撑板1312、第三支撑板1313由层叠状态翻转 展开，与卷轴11滑动连接的第一支撑板1311、与安装件12滑动连接的第二支撑板1312均向上滑动以与第三支撑板1313平齐，以为柔性显示面板10提供支撑，其中，第三支撑板1313位于第一支撑板1311和第二支撑板1312之间，多个第一支撑板1311、多个第二支撑板1312和一个第三支撑板1313沿第二方向X排列。

在一种可行的实施方式中，如图12所示，卷曲组件1还包括：可伸缩连接件14。可伸缩连接件14设置于支撑件13背离柔性显示面板10的一侧，可伸缩连接件14的一端与卷轴11连接、另一端与安装件12连接，可伸缩连接件14可沿第二方向X伸缩。
其中，可伸缩连接件14沿卷第二方向X伸缩，以使卷轴11与安装件12之间的距离增大或减小，进而带动第一支撑件131展开或收纳。
在一种可行的实施方式中，如图12所示，卷曲组件1还包括：驱动件15。驱动件15与可伸缩连接件14连接，用于驱动可伸缩连接件14沿第二方向X伸缩。
其中，可伸缩连接件14可选用沿第二方向X具有支撑作用的结构，以在支撑件13选用弹性支撑网时，保持柔性显示面板10的展开状态，防止由于弹性支撑网的自身弹性回弹而造成柔性显示面板10恢复收纳状态。
具体地，弹性支撑网背离柔性显示面板10的一侧表面可通过支撑连接件与可伸缩连接件14连接，一方面可进一步提升对柔性显示面板10中间位置的支撑，提升柔性显示面板10的平整度，另一方面可使得可伸缩连接件14的伸缩运动更为平稳。

在上述实施方式中，当第一电机可驱动可伸缩部151伸展时，可沿平行于第一连接部141指向第二连接部142的方向，使第一连接部141与转动部143的中心之间的距离增加，从而使得转动部143旋转，使得沿平行于第一连接部141指向第二连接部142的方向，第一连接杆144与第二连接杆145之间的距离增加，并使得转动部143与第一连接杆144以及第二连接杆145之间的角度增大，以为第一连接部141、第二连接部142提供远离彼此方向的作用力，使得第一连接部141与第二连接部142之间的距离增加，从而实现柔性显示面板10的展开。同时，当第一电机可驱动可伸缩部151收缩时，可沿平行于第一连接部141指向第二连接部142的列方向，使第一连接部141与转动部143的中心之间的距离减小，使得转动部143回转，以使得第一连接部141和第二连接部142之间的距离减小，实现柔性显示面板10的收纳。
在上述实施方式中，可伸缩部151可以为丝杠和与丝杆螺纹配合的第二滑块，第二滑块可固定于第一连接部141的中部，丝杆的第一端101固定于转动部143的中部，另一端与第二滑块螺纹配合，可通过第一电机驱动丝杆旋转，从而调整第二滑块与第一端101之间的距离，以调整第一连接部141中部与驱动件15中部之间的距离。
当卷曲组件1为单向卷绕的卷曲组件时，可通过上述可伸缩连接件14实现安装件12与卷轴11的远离与靠近，从而实现柔性显示面板10的自动展开与收纳。当卷曲组件1为双向卷绕的卷曲组件时，可通过上述可伸缩连接件14实现卷轴11与卷绕轴120的远离与靠近，从而可实现柔性显示面板10双向滑移展开与收纳的动作。
