 本发明的实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
请参照图1至图4，本发明实施例提供的柔性显示装置1包括：显示单元11，包括用于显示的第一表面110以及与所述第一表面110相面对的第二表面112；支架机构12包括：多个支撑单元14，沿所述显示单元11长边或者宽边（即侧边）所在方向间隔设置且固定于所述第二表面112，各所述支撑单元14分别设有开口相对且相互贯通的活动孔140；活动单元16，穿过所述活动孔140内并可相对于所述支撑单元14运动；其中，通过调节所述活动单元16与所述支撑单元14的位置关系以改变形状。
本发明实施例提供的柔性显示装置1通过将活动单元16穿过所述活动孔140并可相对所述支撑单元14运动，通过调节所述活动单元16于所述支撑单元14中的位置以改变显示单元11的形状，从而使得所述显示单元11可发生弯曲程度的变化。优选地，所述弯曲程度可以是由弯曲弧形转变为直板型或者由直板型转变为弯曲弧形，也可以是其他任意弯曲度的变化。
在该实施例中，所述支架机构12位于所述第二表面112上。
在该实施例中，所述显示单元11与所述支撑单元14固定连接，通过调节所述活动单元16以带动所述支撑单元14发生形状改变，从而改变所述显示单元11的形状，即实现所述显示单元11的弯曲或者正常平面显示。当所述显示单元11处于弯曲状态时，其可以穿戴在人体上。
在该实施例中，所述显示单元11为柔性显示屏，例如OLED柔性显示屏；或者，所述显示单元11为柔性触控显示屏。
请参照图3至图6，在该实施例中，所述显示单元11包括第一端部114和第二端部116，当所述显示单元11处于弯曲状态时，所述第一端部114和所述第二端部 116相互靠近甚至相互连接；当所述显示单元11处于正常平面显示状态时，所述第一端部114和所述第二端部116为所述显示单元11的两相对侧边。所述活动单元16包括与所述第一端部114相对应的第一端160以及靠近所述第二端部116的第二端162，通过调节所述第二端162相对于所述第二端部116的位置，以通过所述支撑单元14带动所述显示单元11发生弯曲变形。
请参照图1至图3，进一步地，所述活动单元16包括：柔性基材166，由柔性材料制成且与所述显示单元11相对设置；多个刚性件164，沿所述显示单元11长边或者宽边所在方向（即平行于支撑单元14的方向）间隔设置且与所述柔性基材 166固定连接，相邻支撑单元14之间的间隔小于所述刚性件164在该间隔方向上的宽度。可以理解地，所述刚性件164与所述支撑单元14相对应，且设置方向与所述支撑单元14的设置方向相同，即同时沿所述显示单元11的长边所在方向或者宽边所在方向间隔设置。具体地，当所述刚性件164和所述支撑单元14沿所述显示单元11的长边所在方向间隔设置时，所述显示单元11在弯曲后可以适用于人体穿戴，如图3所示；当所述刚性件164和所述支撑单元14沿所述显示单元11的宽边所在方向间隔设置时，所述显示单元11在弯曲后可以起到减小空间占有量，便于握持。
在该实施例中，所述柔性基材166固定连接于各所述刚性件164之间，以使所述活动单元16成一体化设置。在其他实施例中，所述柔性基材166为片状一体化设置，所述刚性件164间隔固定设置于所述柔性基材166上。
请参照图1至图3以及图5和图6,优选地，所述活动单元16还包括：驱动单元168，如图13所示，设置于所述柔性基材166末端并用于拉动所述柔性基材166以使所述刚性件164相对于所述支撑单元14移动。可以理解，所述驱动单元168与所述活动单元16的第二端162连接并带动所述第二端162相对于所述显示单元11的第二端运动，以使所述刚性件164收容于所述活动孔140内或者从所述活动孔140内抽出。
请参照图1和图3以及图8，进一步地，所述刚性件164容置于对应的一个所述活动孔140内时，所述柔性显示装置1的弯曲程度可以发送变化。可以理解，通过拉动所述活动单元16的第二端162以使所述活动单元16相对于所述支撑单元14运动，当持续拉动所述柔性基材166时，使得所述刚性件164完全容置于所述活动孔140内，这样，所述显示单元11可以发生弯曲变形，例如，由直板状态转换为弯曲弧形状态，以适用于穿戴。
请参照图3，优选地，所述活动单元16的一端与所述显示单元11的一端固定且另一端处于自由状态，所述柔性基材166具有弹性伸缩特性。可以理解地，所述活动单元16的第一端160固定于所述显示单元11的第一端部114处，所述第二端 162处于自由状态。所述第二端162在驱动单元168的拉动作用下，由于所述柔性基材166可弹性拉伸，所述柔性基材166于所述支撑单元14中长度变短，从而使得所述支撑单元14带动所述显示单元11发生弯曲变形。反之，所述显示单元11呈现正常平面显示状态。
请参照图1和图2以及图8，优选地，所述活动单元16的两端均处于自由状态。可以理解，所述第一端160和所述第二端162均处于自由状态。当所述驱动单元 168拉动其中任意一端时，所述活动单元16沿方向A在所述支撑单元14中平移，使得所述刚性件164完全容置于所述活动孔140内，这样，所述显示单元11可以发生弯曲变形，例如，由直板状态转换为弯曲弧形状态，以适用于穿戴。
请参照图1和图2以及图7和图9，进一步地，各所述刚性件164相对两侧收容于柔性基材166刚性件164相邻两所述支撑单元14的所述活动孔140内时，所述柔性显示装置1的弯曲程度保持不变。可以理解,当拉动所述活动单元16之第二端162，以使所述刚性件164的相对两侧分别收容于相邻两所述支撑单元14的所述活动孔140内，即各所述刚性件164搭接于相邻两所述支撑单元14上，这样，所述显示单元11的弯曲程度保持不变，例如，拉动前后均处于直板状态。
请参照图3至图6，进一步地，相邻两所述支撑单元14之间的距离依据所述柔性显示装置1所要弯曲的曲率而定。可以理解，例如，对于所述柔性显示装置1的弯曲曲率为：中间的曲率半径大于两端的曲率半径。由于支撑单元14固定于所述显示单元11上，于中间位置处相邻两所述支撑单元14之间的间距小于两端处相邻两所述支撑单元14之间的间距，具体地，对于曲率半径较大的地方，对应的两相邻支撑单元14之间的间距较小；对于曲率半径较小的地方，对应的两相邻支撑单元14之间的间距较大。
请参照图4，优选地，相邻两所述支撑单元14之间的距离沿所述显示单元11的中间向两端由小到大设置。可以理解，由于所述柔性显示装置1的弯曲曲率是逐渐变化过程，即由其中间至两端的曲率为由小变大的过程，那么对应的相邻两所述支撑单元14之间的距离为由小到大变化设置，这样可以有效保障弯曲的连续性和可靠性。
请参照图3，可选地，各所述支撑单元14与各所述刚性件164相对应而设置，且相邻两所述支撑单元14之间的距离与对应的相邻两所述刚性件164之间的距离相同。可以理解地，当所述显示单元11处于弯曲状态时，所述刚性件164完全容置于所述活动孔140内并与所述支撑单元14相对应，相邻两所述支撑单元14之间的距离与对应的相邻两所述刚性件164之间的距离相同，其间距变化规律为：沿所述显示单元11弯曲方向由中间至两端呈由小到大变化。
请参照图3和图4，进一步地，所述多个支撑单元14至少包括：两个第一支撑块142，沿所述显示单元11的两相对侧边而设置；一个第二支撑块144，位于两所述第一支撑块142之间并位于长边或者宽边的中间位置。可以理解，所述第一支撑块142关于所述第二支撑块144对称设置，利用所述第一支撑块142和所述第二支撑块144形成供所述活动单元16运动的轨道，以便于带动所述显示单元11发生变形。通过在显示单元11的两侧分别设置一第一支撑块142以及于其中间位置设置一第二支撑块144，这样可以保证所述显示单元11于弯曲变形过程中，不容易出现折断或者褶皱现象，从而保证弯曲变形的连续性。
请参照图3和图4，优选地，所述支撑单元14还包括位于所述第一支撑块142与所述第二支撑块144之间的至少一个第三支撑块146。所述第一支撑块142和所述第三支撑块146分别关于所述第二支撑块144对称设置，为了进一步地加强显示单元11弯曲变形的连续性，在相应的第一支撑块142和第二支撑块144之间设置至少一个第三支撑块146，并保证各支撑块之间的间距满足上述关于支撑单元14间距设置规律。可选地，所述第一支撑块142与所述第三支撑块146之间的距离大于所述第二支撑块144与所述第三支撑块146之间的距离。
请参照图10，本发明实施例还提供了一种电子装置包括壳体4以及上述柔性显示装置1。所述壳体4与显示单元11相对设置并形成容置腔体，所述支架机构12设置于该容置腔体内。所述柔性显示装置1具有与上述各实施例中柔性显示装置1相同的结构和连接关系，且具有相同的作用和效果，此处不赘述。
请参照图13，进一步地，所述电子装置还包括：控制装置2，与所述柔性显示装置1电性连接；其中，所述控制装置2将其产生的控制信号传递至所述柔性显示装置1以驱动所述柔性显示装置1发生形状改变。可以理解，所述控制装置2控制所述驱动单元168的开启与关闭，利用所述控制装置2产生的控制信号以开启所述驱动单元168，并利用所述驱动单元168驱动所述活动单元16相对于支撑单元14运动，从而使所述柔性显示装置1发生形状改变。即使得所述柔性显示装置1由弯曲弧形转变为直板型或者由直板型转变为弯曲弧形。
请参照图13，优选地，所述电子装置还包括：感应器3，与所述控制装置2电连接；其中，所述感应器3发出感应信号并将所述感应信号发送至所述控制装置2，所述控制装置2根据所述感应信号将相应地控制信号发送至所述柔性显示装置1。可选地，所述感应器3为触控模组或者摄像装置或者压力传感器。
请参照图13，例如，当所述电子装置为手机时，如果该电子装置具有电话呼叫进入，使用者按下接听按钮后，所述控制装置2就会生成一个控制信号，该控制信号发送至所述柔性显示装置1并传入所述驱动单元168中，从而开启所述驱动单元168以驱动所述活动单元16相对于所述支撑单元14运动，从而驱动所述显示单元11发生形状改变，即使得该电子装置由弯曲弧形状态转变为直板型，以便于使用者接听电话，如图12所示。反之，当使用者按下挂断按钮后，所述控装置就会生成另一控制信号，该控制信号发送至所述柔性显示装置1并传入所述驱动单元168中，从而开启所述驱动单元168以驱动所述活动单元16相对于所述支撑单元14运动，从而驱动所述显示单元11发生形状改变，即使得该电子装置由直板型转变为弯曲弧形状态，以形成环形腕带便于佩戴，如图11所示。或者，可在特定感测区域来设置所述感应器3，当电子装置为直板型并且显示单元11朝下时，当手触碰到该触控模组或按压到该压力传感器或摄像装置感测到手靠近时，所述感应器3发出需弯曲的感应信号，所述控制装置2根据所述感应信号控制所述柔性显示装置1向上弯曲，此时由于手已经靠近电子装置，因此，弯曲后的电子装置自动佩戴在手上。
上述实施方式中电子装置1在不可变形时是处于直板状态，然而本领域技术人员应当理解，并不限于直板状态，也可以是弯曲状态，可根据实际需要设置。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
