第一柔性屏1021和第二柔性屏1022均为柔性有机发光二极管显示屏。第一柔性屏1021和第二柔性屏1022包括多个阵列排布的有机发光二极管以及多个阵列排布的薄膜晶体管，薄膜晶体管控制有机发光二极管的发光状态。薄膜晶体管包括无机层、金属层等，薄膜晶体管在第一柔性屏和1021和第二柔性屏1022长期处于90°折叠时会因为遭受应力的影响而导致有机发光二极管出现显示异常的问题。
第一支撑机构1011和第二支撑机构1012起到支撑第一柔性屏1021和第二柔性屏1022的作用。第一支撑机构1011和第二支撑机构1012相对设置且活动连接。第一支撑机构1011和第二支撑机构1012之间具有缝隙101a，以为第一支撑机构1011和第二支撑机构1012折叠时的相对运动提供运动空间。第一柔性屏1021设置于第一支撑机构1011上且延伸至缝隙101a，第二柔性屏1022设置于第二支撑机构1012上且延伸至缝隙101a。
第一支撑机构1011具有第一支撑面1011a，第一支撑面1011a为平面，第一支撑面1011a上设置有第一柔性屏1021，第一柔性屏1021可以粘接或者卡接于第一支撑面1011a上。第二支撑机构1012具有第二支撑面1012a，第二支撑面1012a上设置有第二柔性屏1022，第二柔性屏1022可以粘接或卡接于第二支撑面1012a上。第一支撑机构1011还具有第一倾斜面1011b，第一倾斜面1011b与第一支撑面1011a连接且两者的夹角大于90度且小于180度，第一倾斜面1011b上设置有第一形变件1031，以使得第一形变件1031体积收缩为0时，第一柔性屏1021折叠角为钝角，避免第一柔性屏102的折叠角小于或等于90度而对薄膜晶体管造成损伤。第二支撑机构1012具有第二倾斜面1012b，第二倾斜面1012b与第二支撑面1012a连接且两者的夹角大于90度且小于180度，第二倾斜面1012b上设置有第二形变件1032。
第一支撑机构1011和第二支撑机构1012之间铰接。可折叠显示模组100包括第一连接杆1041以及第二连接杆1042，第一连接杆1041的一端与第一支撑机构1011铰接，第二连接杆1042的一端与第二支撑机构1012铰接，第一连接杆1041的另一端和第二连接杆1042的另一端铰接。第一连接杆1041设置于第一支撑机构1011的侧面，第二连接杆1042设置于第二支撑机构1012的侧面。
第一形变件1031设置于第一柔性屏1021和第一支撑机构1011之间，第二形变件1032设置于第二柔性屏1022和第二支撑机构1012之间。第一形变件1031和第二形变件1032均为气囊。气囊在无空气时充气体积膨胀，气囊在体积膨胀时通过放气体积收缩。气囊具有弹性。气囊在自然状态下为气囊中气体量接近0且处于压缩状态。也可以通过控制气囊中气体的含量以控制第一变形件1031和第二形变件1032的体积。
如图1所示，可折叠显示模组100处于展平状态时，第一形变件1031和第二形变件1032均体积膨胀，第一柔性屏1011延伸至缝隙101a的部分和第二柔性屏1012延伸至缝隙101a的部分无缝拼接。具体地，第一形变件1031和第二形变件1032的截面为直角三角形。第一形变件1031与第一柔性屏1021之间的接触面为互相垂直的面，第二形变件1032与第二柔性屏1022之间的接触面为互相垂直的平面，以实现第一柔性屏1021和第二柔性屏1022在可折叠显示模组处于展平状态的无缝拼接，提供良好的显示体验。
如图2所示，可折叠显示模组100处于折叠状态时，第一形变件1031和第二形变件1032均体积收缩，第一柔性屏1021和第二柔性屏1022不存在直角折叠，使得第一柔性屏1021和第二柔性屏1022中的薄膜晶体管受的应力最小，减少可折叠显示模组100在折叠过程中受的应力作用。可折叠显示模组100处于折叠状态时，第一支撑机构1011和第二支撑机构1012之间的夹角小于180度且大于或等于0度，例如90度。体积收缩可以为气囊中的气体含量为0，此时气囊处于自然状态，体积收缩也可以为气囊中的气体相比于气囊完全膨胀时少。
第一柔性屏1021的长度等于第一支撑面1011a的长度和第一倾斜面1011b的长度之和，第二柔性屏1022的长度等于第二支撑面1012a的长度和第二倾斜面1012b的长度之和，以使得可折叠显示模组在展平状态时能实现无缝拼接且在折叠状态时柔性屏折叠部分较少，减少柔性屏上的薄膜晶体管受折叠应力作用而影响显示效果。
本申请实施例可折叠显示模组通过在支撑机构和柔性屏之间设置形变件，第一形变件和第二形变件在可折叠显示模组处于展平状态时体积膨胀，使第一柔性屏和第二柔性屏之间实现无缝拼接，以提供更好的显示体验。
可折叠显示模组100还包括充放气阀门105，第一支撑机构1011和第二支撑机构1012具有容纳腔体，充气阀门105设置于容纳腔体中。可折叠显示模组100需要展开以进行显示时，充放气阀门105打开且气体注入至第一形变件1031和第二形变件1032，以使第一形变件1031和第二形变件1032体积膨胀。第一形变件1031和第二形变件1032充气到预定形状后，充放气阀门105关闭。可折叠显示装置100需要折叠时，充放气阀门105打开，第一形变件1031和第二形变件1032中的气体释放出，第一形变件1031和第二形变件1032体积收缩，第一形变件1031和第二形变件1032中的气体接近于0。充放气阀门105的数目为多个，以快速实现充气和放气。
在本实施例中，可折叠显示模组100还包括控制单元106，控制单元106用于控制充放气阀门105的开合。控制单元106可以为按键，控制单元106可以嵌入第一支撑机构和第二支撑结构中，与音量按键等一起设置，也可以集成到触控屏控制。
如图3所示，其为本申请实施例第一形变件与吸排气装置连接的示意图。可折叠显示模组100还包括第一输气管1071、吸排气装置1073以及第二输气管1072，第一输气管1071的一端与空气连通，第一输气管1071的另一端与吸排气装置1073连接，第二输气管1072的一端与吸排气装置1073连接，第二输气管1072的另一端与第一形变件1031。第二输气管1072包括输气主管以及输气支管，充放气阀门105设置于第二输气管1072的支管上。吸排气装置1073为吸气球，吸排气装置1073具有弹性，在无外力作用下呈体积完全膨胀状态。对吸排气装置1073施加压力后，吸排气装置1073体积压缩，再移除施加的外力，空气从第一输气管1071进入至吸排气装置1073，充放气阀门105打开，空气从吸排气装置1073经第二输气管1072传输至吸排气装置1073，以使空气注入至第一形变件1031中，使第一形变件1031体积膨胀。第二形变件1032体积膨胀的原理与第一形变件1031相同，此处不作详述。可以理解的是，吸排气装置1073也可以为电动式抽排气装置。
