下面将结合附图对本申请实施方式提供的柔性显示装置进行详细描述。
请参照图1至图2，图1为本申请一实施方式提供的柔性显示装置在第一状态下的立体示意图。图2为图1的柔性显示装置在第一状态下的部分侧视图。柔性显示装置100包括第一壳体10、第二壳体20以及柔性显示屏30。第一壳体10具有第一表面10a和第二表面10b。第一表面10a与第二表面10b相对设置。第二壳体20设置于第一壳体10一侧。柔性显示屏30的一端可卷曲地连接于第一壳体10上，另一端固定连接于第二壳体20。柔性显示屏30能够在第一壳体10与第二壳体20之间展开或者收缩。柔性显示装置100具有第一形态。在第一形态下，第二壳体20远离第一壳体10，柔性显示屏30与第一表面10a形成第一夹角α。第一夹角的大小范围为大于0度且小于180度请参照图3至图5，图3为图1的柔性显示装置在第二状态下的立体示意图。图4为图1的柔性显示装置在第二状态下的另一个角度的立体示意图。图5为图1的柔性显示装置在第二状态下的部分侧视图。柔性显示装置100还具有第二形态。在第二形态下，第二壳体20位于第一壳体10的一侧，柔性显示屏30覆盖于第二表面10b上。其中，第一形态也可以称为笔记本电脑形态。第二形态也可以称为平板电脑形态。
本申请的柔性显示装置100的柔性显示屏30能够随着第二壳体20与第一壳体10的相对运动而展开或者收缩，从而在第一形态与第二形态之间进行变换。在第一形态下，第二壳体20远离第一壳体10，柔性显示屏30与第一表面10a形成第一夹角α，此时，柔性显示装置100能够作为笔记本电脑使用。在第二形态下，第二壳体20位于第一壳体10的一侧，柔性显示屏30覆盖于第二表面10b上，此时，柔性显示装置100能够作为平板电脑使用。
柔性显示装置100还具有第三形态。请参考图6和图7，图6为图1的柔性显示装置在第三形态下的立体示意图。图7为图1的柔性显示装置在第三形态下的部分侧视图。在第三形态下，柔性显示屏30收起，第二壳体20紧贴于第一壳体10的一侧。第三形态也可以称为关机形态。请参考图8，图8为图1的柔性显示装置在第四形态下的部分侧视图。在第四形态下，第二壳体20远离第一壳体10，柔性显示屏30与第一表面10a形成第二夹角β。第二夹角β大于第一夹角α。第二夹角β的大小范围为大于或者等于180度且小于360度。第四形态也可以称为带支架的平板电脑形态。以下，对柔性显示装置100的各部件以及形态进行详细描述。
第一壳体10在第一形态下作为笔记本电脑的底座；在第二形态下作为平板电脑的背板；在第三形态下作为柔性显示装置100的外壳；在第四形态下作为平板电脑的支架。本申请不限定第一壳体10的形状。在一个实施方式中，为了兼容本申请的多种形态，第一壳体10大致呈长方形。第一壳体10的长边方向为第一方向D1。短边方向为第二方向D2。在一个实施方式中，第一壳体10的第一表面10a上设置有键盘K以及触摸板T。在另一个实施方式中，键盘K可拆卸地安装于第一表面10a。在第一形态下，柔性显示装置100作为笔记本电脑使用，相较于虚拟键盘，设置于第一表面10a的键盘K能够提供用户真实触感，提升用户体验。第二表面10b为平坦表面。从而在第二形态下，柔性显示屏30可以设置于第二表面10b上以进行显示和触控。
第一壳体10还用于收容柔性显示屏30。柔性显示屏30的一端可卷曲地设置于第一壳体10。具体地，第一壳体10包括第一卷轴11。柔性显示屏30的一端可卷曲地设置于第一卷轴11上，另一端固定连接于第二壳体20。柔性显示屏30可以卷曲到第一卷轴11上，以减小柔性显示装置100的尺寸，从而提高便携性。本申请不限定第一卷轴11的位置，其可以位于第一壳体10朝向第二壳体20的表面，也可以收容于第一壳体10中。如图2所示，在一个实施方式中，为了防止柔性显示屏30受到外力损伤，第一壳体10包括中空腔体101。第一卷轴11收容于中空腔体101中。第一卷轴11沿第一方向D1延伸。第一壳体10靠近第二壳体20的一端还开设有开口102。开口102与中空腔体101相连通。柔性显示屏30经由开口102连接于第二壳体20与第一卷轴11之间。具体地，第一卷轴11设置于中空腔体101远离开口102的一端。可以理解，中空腔体101还可以用于设置柔性显示装置100的其他部件，例如柔性显示屏30的驱动电路板等。
第二壳体20设置在第一壳体10的第二方向D2，即短边方向上。在一个实施方式中，第二壳体20沿第一方向D1延伸，且长度与第一壳体10的长度大致相同。本申请不限定第二壳体20的形状。第二壳体20的形状可以为圆筒状、长方体、棱柱等。在本实施方式中，第二壳体20为圆筒状。具体地，第二壳体20包括第二卷轴21。第二卷轴21沿第一方向D1延伸。第二卷轴21通过旋转，可以使柔性显示屏30卷绕在第二壳体20上，包覆第二壳体20的至少部分外表面，以扩大显示面积。例如，请参考图3，在第二形态下，柔性显示屏30卷曲于第二卷轴21上，并覆盖第二卷轴21的至少部分表面。柔性显示装置100还可以具有第五形态。请参考图9，第五形态是在第一形态的基础上，旋转第二卷轴21，使柔性显示屏30卷绕在第二壳体20上，包覆第二壳体20的至少部分外表面，以扩大显示面积。在另一种实施方式中，柔性显示屏30包括显示面30a和非显示面30b。显示屏30的非显示面30b与第二壳体20固定连接。例如，当第二壳体20包括第二卷轴21时，柔性显示屏30始终卷绕在第二卷轴21上，无论柔性显示装置100的形态如何变化，第二壳体20均位于柔性显示屏30的非显示面30b上，以实现最大面积的显示。
第二壳体20用于相对于第一壳体10相对运动。具体地，第二壳体20可以远离或者靠近第一壳体10，也可以围绕第一壳体10转动，也可以一边远离或者靠近第一壳体10并一边围绕第一壳体10转动。柔性显示屏30可以随着第二壳体20与第一壳体10的相对运动在第一壳体10与第二壳体20之间展开或者收缩。
柔性显示屏30用于显示图像。柔性显示屏30可以在第二方向D2上卷曲到第一卷轴11上，或者可以在第二方向D2上从第一卷轴11展开。在本实施方式中，柔性显示屏30还可以在第二方向D2上卷曲到第二卷轴21上，或者可以在第二方向D2上从第二卷轴21展开。
柔性显示屏30可以为有机发光二极管（Organic Light-emitting Diode，OLED）显示屏、主动矩阵有机发光二极管（Active Matrix Organic Light-emitting Diode，AMOLED）显示屏、被动矩阵有机发光二极管(Passive Matrix Organic Light-emitting Diode，PMOLED)显示屏、量子点有机发光二极管（Quantum Dot Light-emitting Diode，QLED）显示屏、微发光二极管（Micro Light-emitting Diode，Micro-LED）显示屏或者次毫米发光二极管（Mini Light-emitting Diode，Mini-LED）显示屏。
在第一形态下，柔性显示屏30与第一表面10a形成第一夹角α。第一夹角α的大小范围为大于0度且小于180度。在第二形态下，柔性显示屏30覆盖于第二表面10b上。柔性显示屏30还包括触控模组。在第二形态下，第一壳体10用于提供触控模组的刚性支撑面，柔性显示屏30可以实现触控功能。具体地，平坦的第二表面10b作为触控模组的支撑面。
请参考图1，柔性显示装置100还包括支撑件40。在本实施方式中，支撑件40的一端转动连接于第一壳体10，另一端固定连接于第二壳体20。在第一形态下，支撑件40与第一表面形成第三夹角γ以支撑第二壳体20。第三夹角γ的大小范围为大于0度且小于180度。在第二形态下，支撑件40平行于第一壳体10，以将柔性显示屏30固定于第二表面10b。具体地，第二壳体20还包括位于第二卷轴21两侧的连接部22。支撑件40固定连接于连接部22。在本实施方式中，连接部22为插销。支撑件40中开设有插孔。插销嵌入插孔中与支撑件40固定连接。可以理解，本申请并不限定连接部22和支撑件40的固定方式。
支撑件40设置于第一壳体10在第一方向D1上的两侧。在一种实施方式中，支撑件40可伸缩。具体地，支撑件40包括第一伸缩杆41、第二伸缩杆42、第三伸缩杆43以及第四伸缩杆44。第一伸缩杆41转动连接于第一壳体10。第二伸缩杆42固定连接于第二壳体20。第三伸缩杆43一端滑动连接于第一伸缩杆41，另一端滑动连接于第四伸缩杆44。第四伸缩杆44一端滑动连接于第三伸缩杆43，另一端滑动连接于第二伸缩杆42。可以理解，本申请不限定支撑件40包括的伸缩杆的数目。并且，本申请也不限定支撑件40的伸缩结构，只要是能够进行长度变化的结构，均可用作本申请的支撑件40。具体例子可以列举“Z”字形或者“X”字形的铰链结构等。由于支撑件40可以围绕第一壳体10转动，通过转动支撑件40，即可调整第一壳体10与第二壳体20的相对位置，从而调整柔性显示屏30与第一壳体10之间的角度。由于支撑件40可以伸缩，通过调整支撑件40的长度，即可调整第一壳体10与第二壳体20之间的距离，从而调整柔性显示屏30的大小。
在一种实施方式中，支撑件40可以是电动支撑件40。请参考图2，柔性显示装置100还包括支撑件40的驱动组件50。驱动组件50用于驱动支撑件40伸缩和/或旋转。驱动组件50可以设置于中空腔体101中。驱动组件50通过驱动支撑件40的伸长，带动第二壳体20相对第一壳体10运动，使柔性显示屏30从第一卷轴11上释放从而在第一壳体10与第二壳体20之间展开。反之，驱动组件50通过驱动支撑件40的缩短，并配合第一卷轴11的转动，使柔性显示屏30往第一卷轴11上卷绕从而在第一壳体10与第二壳体20之间缩短。此外，通过驱动支撑件40的转动，可以调整柔性显示屏30与第一壳体10的角度，使柔性显示装置100在多个形态之间变化。
需要说明的是，在一种实施方式中，支撑件40可拆卸地连接于第一壳体10和/或第二壳体20。具体地，在一种实施方式中，在第三形态下，支撑件40从第一壳体10和第二壳体20下拆卸下来。在从第三形态变换为第一形态的过程中，使第二壳体20远离第一壳体10，柔性显示屏30展开，再将支撑件40分别安装于第一壳体10和第二壳体20上，将第二壳体20支撑于第一壳体10上，从而固定柔性显示屏30。在从第三形态或者第一形态变换为第二形态的过程中，支撑件40可以从第一壳体10和第二壳体20下拆卸下来，将第二壳体20调整至第一壳体10在第二方向D2上远离开口102的一侧，使柔性显示屏30覆盖在第二表面10b上，再将支撑件40分别安装于第一壳体10和第二壳体20上，以固定第一壳体10与第二壳体20的位置。可以理解，在第二状态下，第二壳体20可以与第一壳体10接触，也可以保持一定距离。在一种实施方式中，支撑件40可以可转动地连接于第一壳体10，但与第二壳体20可拆卸连接，在调整完第二壳体20的位置后，再与第二壳体20连接，以固定第二壳体20的位置。请参考图10，图10为本申请另一种实施方式的柔性显示装置在第二形态下的立体示意图。在另外一种实施方式中，在第二形态下，支撑件40从第一壳体10和第二壳体20下拆卸下来。此时，柔性显示装置100还包括固定件60。在第二形态下，固定件60将第二壳体20固定于第一壳体10上，从而将柔性显示屏30固定于第二表面10b。
在一种实施方式中，特别当是支撑件40可拆卸地连接于第一壳体10和/或第二壳体20时，支撑件40也可以是固定长度。
请再次参考图2和图5，柔性显示装置100还包括第一滚轮70和第二滚轮80。第一滚轮70和第二滚轮80均位于第一卷轴11与第二壳体20之间。在一种实施方式中，第一滚轮70与第二滚轮80相对设置。在一个实施方式中，第一滚轮70和第二滚轮80均设置于开口102中，且分别位于第一壳体10在厚度方向上的两侧。第一滚轮70和第二滚轮80用于在柔性显示屏30展开或收缩的过程中，与柔性显示屏30相对滑动，以防止柔性显示屏30摩擦受损。在第一形态下，柔性显示屏30与第一滚轮70相接触。并且，柔性显示屏30以第一滚轮70为拐点进行弯折，由于柔性显示屏30与第一滚轮70的曲面之间发生面接触，能够减小摩擦力，从而保护柔性显示屏30。在第二形态下，柔性显示屏30与第二滚轮80相接触。并且，柔性显示屏30以第二滚轮80为拐点进行弯折，由于柔性显示屏30与第二滚轮80的曲面之间发生面接触，能够减小摩擦力，从而保护柔性显示屏30。
以下，对本申请的柔性显示装置100的第一形态至第五形态及其变换过程进行详细描述。本申请的柔性显示装置100可以在第一形态至第五形态的任意两个形态之间发生变化。以下，仅举例说明其变化过程。
首先，请参考图6和图7，第三形态可以为柔性显示屏30的初始形态。在第三形态下，第二壳体20紧贴于第一壳体10在第二方向D2上的一侧。柔性显示屏30的一端可卷曲地固定在第一卷轴11上，另一端固定在第二壳体20上。柔性显示屏30与第一卷轴11一起收容于第一壳体10的中空腔体101内。支撑件40位于第一壳体10在第一方向D1上的两侧，且平行于第一壳体10设置，减小柔性显示装置100占用的空间。
请参考图2，在从第三形态变换为第一形态的过程中，驱动组件50驱动支撑件40伸长到预定长度后停止，带动第二壳体20远离第一壳体10，使柔性显示屏30从第一卷轴11上释放从而在第二方向D2上展开；然后，驱动组件50再驱动支撑件40朝远离第一表面10a的方向旋转至预定角度后停止，使柔性显示屏30与第一表面10a形成第一夹角α。在此过程中，柔性显示屏30与第一滚轮70相对滑动。可以理解，驱动组件50驱动支撑件40伸长和旋转的顺序可以颠倒，也可以同时驱动支撑件40伸长并旋转。
请参考图9，由于在第一形态下，第二壳体20位于柔性显示屏30的显示面30a上，可以通过转动第二卷轴21，将柔性显示屏30卷绕在第二卷轴21上，使柔性显示屏30覆盖第二壳体20表面，将第二壳体20变换至柔性显示屏30的非显示面30b上，从而提高柔性显示装置100的显示面积，此为第五形态。
请参考图8，在从第一形态或者第五形态变换为第四形态的过程中，驱动组件50驱动支撑件40继续朝远离第一表面10a的方向旋转至预定角度后停止。在此过程中，支撑件40带动第二壳体20围绕第一壳体10旋转，并使柔性显示屏30与第一表面10a形成第二夹角β。第二夹角β的大小范围为大于或者等于180度且小于360度。在此形态下，柔性显示屏30可以显示画面，第一壳体10与支撑件40之间形成稳定的三角形，可以将柔性显示屏30支撑在平面上。在此过程中，柔性显示屏30与第二滚轮80相对滑动。
请参考图5，在从第四形态变换为第二形态的过程中，驱动组件50驱动支撑件40继续朝靠近第二表面10b的方向旋转，直到第二壳体20位于第一壳体10在第二方向D2上的一侧，且柔性显示屏30覆盖在第二表面10b上。并且，柔性显示屏30覆盖于第二卷轴21朝向第一壳体10的表面上。在俯视第二表面10b时，柔性显示屏30从第二表面10b延伸至第二卷轴21的表面，从而进行全面屏显示。
请参考图6，在从第一形态或者第二形态变换为第三形态的过程中，驱动组件50通过驱动支撑件40朝靠近第一表面10a的方向旋转预定角度，直到支撑件40与第一壳体10平行的位置并停止，驱动组件50再驱动支撑件40缩短，配合第一卷轴11的转动，使柔性显示屏30往第一卷轴11上卷绕从而在第一壳体10与第二壳体20之间缩短。最终，使柔性显示屏30完全卷绕在第一卷轴11上，第二壳体20紧贴于第一壳体10的一侧。
本申请提供一种柔性显示装置。柔性显示装置包括第一壳体、第二壳体以及柔性显示屏。第一壳体具有第一表面和第二表面。第一表面与第二表面相对设置。第二壳体设置于第一壳体一侧。柔性显示屏的一端可卷曲地连接于第一壳体上，另一端固定连接于第二壳体上。柔性显示屏能够在第一壳体与第二壳体之间展开或者收缩。柔性显示装置具有第一状态和第二状态。在第一状态下，第二壳体远离第一壳体，柔性显示屏与第一表面形成第一夹角，第一夹角的大小范围为大于0度且小于180度；在第二状态下，第二壳体位于第一壳体的一侧，柔性显示屏覆盖于第二表面上。
本申请的柔性显示装置的柔性显示屏能够随着第二壳体与第一壳体的相对运动而展开或者收缩，从而在第一状态与第二状态之间进行变换。在第一状态下，第二壳体远离第一壳体，柔性显示屏与第一表面形成第一夹角，此时，柔性显示装置能够作为笔记本电脑使用。在第二状态下，第二壳体位于第一壳体的一侧，柔性显示屏覆盖于第二表面上，此时，柔性显示装置能够作为平板电脑使用。即，本申请的柔性显示装置能够以笔记本电脑和平板电脑至少两种形态使用。
此外，本申请的柔性显示装置还能作为带支架的平板电脑使用，使用形态丰富。并且，本申请的柔性显示装置还具有结构简单、成本低廉的优点。
另外，请再次参考图1和图2，本申请的另一实施方式还提供一种柔性显示装置100，其包括：第一壳体10、第二壳体20、柔性显示屏30以及支撑件40。
第一壳体10具有第一表面10a和第二表面10b。第一表面10a与第二表面10b相对设置。
第二壳体20设置于第一壳体10的一侧。
柔性显示屏30的一端可卷曲地连接于第一壳体10上，另一端固定连接于第二壳体20上。柔性显示屏30能够在第一壳体10与第二壳体20之间展开或者收缩。
支撑件40的一端转动连接于第一壳体10，另一端固定连接于第二壳体20。在一种实施方式中，支撑件40可伸缩。关于本实施方式中的柔性显示装置100的第一壳体10、第二壳体20、柔性显示屏30以及支撑件40的具体结构，可以参考以上描述，在此省略其说明。
本实施方式的柔性显示装置，通过能够在第一壳体与第二壳体之间转动的支撑件，带动第二壳体相对于第一壳体运动，从而柔性显示屏能够随着第二壳体与第一壳体的相对运动而展开或者收缩，从而在第一状态与第二状态之间进行变换，使柔性显示装置能够以笔记本电脑和平板电脑至少两种形态使用。
以上对本申请实施方式提供了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施方式的说明只是用于帮助理解本申请。同时，对于本领域的技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
