如图1所示，本发明提供一种柔性OLED显示器；其中本发明的柔性OLED显示器可以用于动态弯折。本发明的柔性OLED显示器包括：柔性OLED显示面板103、支撑框架102以及缓冲层101；
其中，所述支撑框架102位于所述缓冲层101表面上，所述柔性OLED          显示面板位于所述支撑框架102表面上。
如图2所示，本发明柔性OLED显示器处于平面状态下的剖视图中，所述支撑框架102具有弯折区域201和非弯折区域，所述弯折区域201位于所述支撑框架102的中心位置；

如图4所示，本发明柔性OLED显示器中所述铰链204包括支撑构件401和轴心构件402。所述支撑构件401固定连接在所述支撑框架102的侧面；所述轴心构件402固定连接在所述支撑构件401的表面；所述轴心构件402的形状为弹簧状。
装配本发明柔性OLED显示器时，首先在所述柔性OLED面板103的下表面位置装配所述支撑框架102，然后在所述支撑框架102的下表面处沉积所述缓冲层101。所述支撑框架102的制造，可以采用左右两部分结合装配的方式。首先在所述支撑框架102位于所述弯折区域201的一侧面焊接所述支撑构件401，所述支撑构件401的表面固定连接所述轴心构件402的一部分。所述第一保护构件202的左端分别与所述支撑框架102的上表面和所述支撑构件401嵌合固定连接，组成了所述支撑框架102的左侧；所述第二保护构件203的右端分别与所述支撑框架102的下表面和右边的所述支撑构件401嵌合固定连接，组成了所述支撑框架102的右侧。
所述铰链204与所述支撑框架102以及所述第一保护构件202与制程框架可以采用焊接、胶接等方式连接。将所述支撑框架102的两端完整装配后，完整保护所述第一保护构件202与所述支撑框架102之间的连接和所述第二保护构件203与所述支撑框架102之间的连接，组成新型的整体框架，得到了所述支撑框架102。这样，本发明柔性OLED显示器在动态弯折区域存在所述铰链204的结构，使得在弯折过程中，由于两侧的所述支撑构件401对中间弯折的所述轴心构件402的拉力，所述铰链204逐渐拉紧并且缩小，同时为所述柔性OLED显示面板103弯折形成的余量提供空间。
本发明的有益效果为：本发明所提供的柔性OLED显示器，将位于弯曲区域的支撑框架中设置一种新型铰链结构，为OLED显示面板弯折形成的余量提供空间，进一步实现了柔性OLED显示器的动态弯折，更进一步提高了动态弯折柔性OLED显示器的产量。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
