当将绑定区域向显示面板的背后进行弯折时，绑定区域与显示区域之间会出现弯折区域。由于绑定区域与显示区域之间设置有多条用于传输信号的金属信号线，因此当显示面板弯折时，在弯折区域内的金属信号线容易受到应力作用而导致断裂，从而引发信号传输不良，使显示面板无法正常显示。
因此，有必要提供一种气囊组件及柔性面板弯折方法，以解决上述问题。

 本发明的实施方式
为了使本发明的目的、技术手段及其效果更加清楚明确，以下将结合附图对本发明作进一步地阐述。应当理解，此处所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例，并不用于限定本发明。
请参考图1，其示出本发明实施例提供的气囊组件的结构示意图。气囊组件1用于弯折柔性面板，其包括壳体10和弹性膜11。其中，壳体10包括至少一个出气口100和至少一个进气口101。在本发明实施方式中，壳体10包括多个出气口100，多个出气口100于壳体10的长度方向上线性等距地排列。弹性膜11包围壳体10以形成气体容室12，其中出气口100和进气口101连通于气体容室12。具体地，弹性膜11为橡胶膜。在一些实施方式中，弹性膜11利用胶材黏贴于壳体10的二端以形成密闭的气体容室12。气体容室12可充气来膨涨弹性膜11, 藉由膨胀的弹性膜11来弯折柔性面板至所需弯曲曲率。
如图1所示，气囊组件1还包括：压力传感器13、调压阀14、气源15、输气管16和控制器17。其中，压力传感器13设于输气管16内。调压阀14通过输气管16连接气源15及壳体10。输气管16连通于气源15及壳体10的进气口101。控制器17与压力传感器13及调压阀14电连接，用于接收压力传感器13的输出信号且控制调压阀14的开关动作。在一些实施方式中，调压阀14为电磁阀。当调压阀14开启时，气源15可以通过输气管16供气给壳体10；当调压阀14关闭时，气源15无法通过输气管16供气给壳体10。进一步，调压阀14可与外界连通以对气囊组件1进行排气，从而使得气体容室12减压。
请参考图2，其示出根据本发明实施例的柔性面板的弯折方法的流程图。
同时参考图3A-3C，图3A为实施图2的步骤S02、S03、S04的示意图，图3B为实施图2的步骤S04的剖面示意图，图3C为实施图2的步骤S05的剖面示意图。如图3A所示，柔性面板2包括显示区DA、待弯折区域BA及邻接待弯折区域BA的端子区域PA。具体地，柔性面板2为有机发光二极体显示面板。再者，柔性面板2包括柔性基板20、多条通过待弯折区域BA的金属信号线21和设于端子区域PA的绑定端子(图中未示出)，其中金属信号线21与所述绑定端子电性连接。
继续参考图2，柔性面板2的弯折方法包括如下步骤：
步骤S01、提供气囊组件1(如图1所示)。
步骤S02、对所述气囊组件1进行充气。在本发明实施方式中，如图1所示，步骤S02包括：首先，由控制器17控制调压阀14进行开启。图1中，箭头所示的气流不断地向气体容室12内流进。接着，当气体容室12内的气压增加到一预定值时，由压力传感器13输出一第一信号。最后，由控制器17接收所述第一信号并控制调压阀14进行关闭。
步骤S03、使气囊组件1抵靠于待弯折区域BA(如图3A所示)。
步骤S04、如图3A、3B所示，以气囊组件1为支撑轴，对柔性面板2进行弯折，使得柔性面板2的弯折部分紧密接触气囊组件1的表面，并使得端子区域PA位于柔性面板2的背后。图3B示出图1的气囊组件1沿A-A的剖面示意图。于图3B中，多个出气口100于壳体10的圆周上等距地排列。进一步地，箭头所示的气流通过多个出气口100流入气体容室12，使得弹性膜11均匀膨胀。在弯折时，柔性面板2系
Figure 627a
靠在膨胀的弹性膜11上。 藉由在膨胀弹性膜11上对柔性面板2施加弯折力量以弯折柔性面板2至所需的弯曲曲率。不同膨胀程度的弹性膜11可得到不同的弯曲曲率的柔性面板2。如此，本发明的气囊组件可适用来形成不同构形的柔性面板。
步骤S05、于柔性面板2弯折后，对气囊组件1进行排气。如图1所示，步骤S05包括：首先，由控制器17控制调压阀14进行减压。接着，当气体容室12内的气压降低到一预定值时，由压力传感器13输出一第二信号。最后，由控制器17接收所述第二信号并控制调压阀14停止减压。如图3C所示，箭头所示的气流不断地从气体容室12内流出。当气囊组件1排气完成后，气囊组件1与柔性面板2呈分离状态，如此可避免彼此的干涉。
综上所述，本发明提供的气囊组件及柔性面板弯折方法, 主要于柔性面板于弯折过程中提供气囊组件对柔性面板的弯折部分进行支撑，以避免金属信号线受到应力作用而导致断裂，确保显示面板正常显示。
应当理解的是，本发明的应用不限于上述的举例，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，所有这些改进和变换都应属于本发明所附权利要求的保护范围。
 工业实用性
本发明提供气囊组件对柔性面板的弯折部分进行支撑，以避免金属信号线受到应力作用而导致断裂，确保显示面板正常显示。
