需要说明的是，第一方向F1为柔性显示屏10回缩和展开的运动方向，在本实施例中为柔性显示屏10的长度方向。
在一实施例中，柔性显示屏10可以为柔性的OLED显示屏，显示屏包括第一显示部101，以及与第一显示部101连接的第二显示部102，且第一显示部101和第二显示部102之间无缝隙，为整块屏幕。
在一实施例中，第一显示部101背光面可以通过粘合胶贴设在第一支撑壳体201的第一支撑面（即多条第一梳齿2012）上，第一显示部101远离第二显示部102的一侧边与第一支撑壳体的第一主干2011固定贴设。
第二显示部102绕第二支撑壳体202设置，且第二显示部102远离第一显示部101的一侧边绕过第二主干2021与第二支撑壳体202背离第一显示部101的一侧面（即第二支撑壳体202的背面）相对滑动连接。
在一实施例中，如图2、如图4和图5第一显示部101固定连接于第一支撑壳体201上，第二显示部102沿第一方向F1绕设在第二支撑壳体202的外周侧，且第二显示部102与第二支撑壳体202沿第一方向F1滑动连接，第二显示部102远离第一显示部101的一侧边连接有第三显示部103，第三显示部103始终与第一显示部101的出光面朝向相反。
具体地，如图1、图2和图3所示，支撑组件20包括第一支撑壳体201，以及与第一支撑壳体201滑动连接的第二支撑壳体202，第一支撑壳体201和第二支撑壳体202的尺寸相匹配。
在一具体实例中，第一支撑壳体201的大小与第二支撑壳体202的大小相同，第二支撑壳体202相对第一支撑壳体201沿第一方向F1滑动连接，第一支撑壳体201和第二支撑壳体202相对滑动，包括重叠的回缩状态和展开的伸长状态，使得支撑组件20的支撑面积状态在小面积与大面积之间进行切换。
具体地，如图6和图8所示，第一支撑壳体201包括梳形结构，具体包括第一主干2011，第一主干2011上连接多条互相平行的第一梳齿2012，多条第一梳齿2012的形状、尺寸可以相同，第一梳齿2012的长度方向与第一方向F1相同，多个第一梳齿2012靠近第一显示部101的一侧面组成第一支撑面，用于贴设第一显示部101。

具体地，第二主干2021上设置有与第二主干2021平行的多段滚轴，多段滚轴同轴设置且通过固定轴承204转动连接至第二主干2021上，第二显示部102的背光面与滚轴的轴面抵接，能够提高滑移屏滑动（即第二显示部102绕第二支撑壳体202移动）的顺畅程度，减小移动终端滑移屏滑动负载。
具体地，第一梳齿2012和第二梳齿2022实现滑动连接的具体结构可以为：
第一梳齿2012包括第一主体部2012c、第一支撑部2012a和第一止挡部2012b，第一支撑部2012a和第一止挡部2012b分别位于第一主体部2012c朝向第二梳齿2022的两侧面上，第一支撑部2012a和第一止挡部2012b的厚度不作具体限制，优选小于或等于第一主体部的厚度；
第一梳齿2012上，第一支撑部2012a、第一止挡部2012b的设置方式和数量具体不作限制，只要第一支撑部2012a能够与第二止挡部2022b相配合实现沿第一方向F1滑动，第一止挡部2012b能够与第二支撑部2022a相配合实现沿第一方向F1滑动的技术方案均在本申请的保护范围内；
一种实施方式为，第一梳齿2012朝向第二梳齿2022的两侧边分别形成第一方向F1凹槽和凸起，第二梳齿2022朝向第一梳齿2012的两侧边分别形成沿第一方向F1延伸的凹槽和凸起，第一梳齿和第二梳齿通过凹槽和凸起滑动卡接。
在另一实施方式，如图8、图9、图10所示，第一梳齿2012的横剖面(如图8中的A-A’剖面)均为Z字型（Z字形的左右朝向不作限制），即第一支撑部2012a、第一止挡部2012b的数量均为一个。
例如，该Z字形可以为正向的Z字形（如图10）或为反向的Z字形（图11）所示，第一支撑部2012a和第一止挡部2012b的横截面可以为矩形，如图12、图13、图14和图15所示，第一支撑部2012a和第一止挡部2012b的横截面也可以为梯形，该梯形的形状不作限制，第一支撑部2012a和第一止挡部2012b的截面可以为楔形。
第二梳齿2022包括第二主体部2022c、第二支撑部2022a和第二止挡部2022b，第二支撑部2022a和第二止挡部2022b分别位于第二主体部2022c朝向第一梳齿2012的两侧面上，第二支撑部2022a和第二止挡部2022b的厚度不作具体限制，可以小于或等于第二主体部2022c的厚度。
具体地，第二梳齿2022上，第二支撑部2022a、第一止挡部2012b的设置方式和数量具体不作限制，只要第二支撑部2022a能够与第一止挡部2012b相配合实现沿第一方向F1滑动，第二止挡部2022b能够与第一支撑部2012a相配合实现沿第一方向F1滑动的技术方案均在本申请的保护范围内。
在本实施例中，如图8、图9、图10所示，第二梳齿2022的横剖面（如图9中的B-B’剖面）均为Z字型（Z字形的左右朝向不作限制），即第二支撑部2022a、第二止挡部2022b的数量均为一个。
例如，该Z字形可以如图10、图11所示，第二支撑部2022a和第二止挡部2022b的截面可以为矩形，如图12、图13、图14和图15所示，第二支撑部2022a和第二止挡部2022b的截面也可以为梯形，该梯形的形状不作限制，第二支撑部2022a和第二止挡部2022b的梯形可以相同也可以不同，第二支撑部2022a和第二止挡部2022b的截面可以为楔形。
具体地，可以如图16所示，第一梳齿2012的第一支撑部2012a和第一止挡部2012b的横剖面为矩形，第二梳齿2022的第二支撑部2022a和第二止挡部2022b的纵剖面为梯形，第二支撑部2022a和第二止挡部2022b的梯形可以相同也可以不同。
本实施例中第一梳齿2012和第二梳齿2022为并排交错设置的结构，如图17a和图17b所示，以一个第一梳齿2012与两第二梳齿2022的连接单元结构进行举例说明。
如图17a和图17b所示，第一梳齿2012包括第一支撑部2012a和第一止挡部2012b，第二梳齿2022包括第二支撑部2022a和第二止挡部2022b，第一梳齿2012的第一止挡部2012b与其右侧相邻的第二梳齿2022的第二支撑部2022a滑动抵接，第一梳齿2012的第一支撑部2012a与其左侧相邻的另一第二梳齿2022的第二止挡部2022b滑动抵接。
其中，第一支撑部2012a和第二支撑部2022a提供向上的支撑力，第一止挡部2012b和第二止挡部2022b提供向下的稳固力，使得第一梳齿2012和第二梳齿2022均处于平衡状态，实现稳固支撑效果。
通过设置多个上述连接单元结构，多个第一梳齿2012和多个第二梳齿2022形成卡接的稳定结构，以对柔性显示屏10起到良好的支撑效果。
现有技术中的第一梳齿2012和第二梳齿2022的滑动连接方式为滑块与滑槽的滑动连接方式，例如第一梳齿2012为凹形滑槽的结构，第二梳齿2022上对应该凹形滑槽形成有凸形滑块，凸形滑块在该凹形滑槽内滑动，使得第一梳齿2012和第二梳齿2022实现滑动连接，但是该滑动连接结构整体滑动接触面较大，厚度较大，滑动结构占据过多的显示装置的内部空间，严重影响整机续航。
本实施例中，如图6和图7所示，通过设置第一梳齿2012和第二梳齿2022为Z字型，且相邻的第一梳齿2012和第二梳齿2022为交错卡接的结构，使得第一支撑壳体201和第二支撑壳体202的相互锁叠，由于避免了设置凹滑槽和凸型滑块，相对减薄了支撑结构的厚度，预留出更多的内部空间，能够设置更大容量的电池，提升显示装置的整机续航能力，同时相对现有技术的凹滑槽和凸型滑块结构，本实施例中，第一梳齿2012和第二梳齿2022接触的面积较小，减少了第一梳齿2012和第二梳齿2022之间滑动的摩擦阻力，滑动更顺畅，稳定性高。
在一实施例中，第一支撑壳体201和第二支撑壳体202之间可以设置同步传动件，以使第一支撑壳体201和第二支撑壳体202同步传动且滑动更稳定。
柔性显示装置通过第一支撑壳体201与第二支撑壳体202的相对滑动在平展状态和回缩状态之间进行切换；平展状态下，第一显示部101和第二显示部102的出光面位于同一平面，如图2、图3、图4和图5所示，其中，图2和图5为展平状态下的柔性显示装置的背面；回缩状态下，如图1所示，第一显示部101和第二显示部102的出光面相反。
柔性显示装置由回缩状态切换至平展状态，第二支撑壳体202沿第一方向F1向远离第一支撑壳体201的一侧移动，同时，第二显示部102的自由端由第二支撑壳体202靠近第一支撑壳体201的一侧边向第二支撑壳体202远离第一支撑壳体201的一侧边移动，使得第二显示部102的出光面绕第二支撑壳体202的第二主干2021转动，使得第二显示部102的出光面由与第一显示部101的出光面朝向相反切换至与第一显示部101出光面朝向相同。
当柔性显示屏处于回缩状态时，第一支撑壳体201的第一支撑面和第二支撑壳体202的第二支撑面重合，当柔性显示屏处于展开状态时，第一支撑壳体201的第一支撑面和第二支撑壳体202的第二支撑面同平面展开。
在一实施例中，支撑组件20可以为金属或者合金构件。
可以理解的是，通过设置支撑组件20包括第一支撑壳体201和第二支撑壳体202，第一支撑壳体201包括多条第一梳齿2012，第二支撑壳体202包括多条第二梳齿2022，第一梳齿2012包括第一主体部2012c、第一支撑部2012a和第一止挡部2012b，第一支撑部2012a和第一止挡部2012b分别位于第一主体部2012c朝向第二梳齿2022的两侧面上；第二梳齿2022包括第二主体部2022c、第二支撑部2022a和第二止挡部2022b，第二支撑部2022a和第二止挡部2022b分别位于第二主体部2022c朝向第一梳齿2012的两侧面上，第一梳齿2012和第二梳齿2022并排交错设置，且沿第一方向F1相对滑动连接；在垂直第一方向F1的平面上，第一梳齿2012的第一支撑部2012a与相邻的第二梳齿2022的第二止挡部2022b相抵接以使第一支撑部2012a支撑第二止挡部2022b，且第二梳齿2022的第二支撑部2022a与相邻的第一梳齿2012的第一止挡部2012b相抵接以使第二支撑部2022a支撑第一止挡部2012b，实现第一支撑壳体201和第二支撑壳体202的相互锁叠，相对于现有技术的凹滑槽和凸滑块结构，接触面更少，减少了第一梳齿2012和第二梳齿2022之间的摩擦阻力，滑动更顺畅，稳定性高，将第一支撑部2012a和第一止挡部2012b设置于第一梳齿2012朝向第二梳齿2022的两侧面上，将第二支撑部2022a和第二止挡部2022b设置于第二梳齿2022朝向第一梳齿2012的两侧面上，使得第一梳齿2012和第二梳齿2022的卡接的结构也有效降低了支撑组件20的整体厚度，使得柔性显示装置中支撑组件20的体积占比低，进而提高柔性显示装置的整机续航能力。
在一实施例中，如图8~图17a和图17b所示，第一支撑部2012a包括第一接触面C1、第一止挡部2012b包括第二接触面C2，第二支撑部2022a包括第三接触面C3、第二止挡部2022b包括第四接触面C4；
在与第一梳齿2012相邻的两第二梳齿2022中，其中一第二梳齿2022的第四接触面C4与第一梳齿2012的第一接触面C1滑动抵接，另一第二梳齿2022的第三接触面C3与第一梳齿2012的第二接触面C2滑动抵接；
第一接触面C1、第二接触面C2、第三接触面C3和第四接触面C4均为平坦面，且与垂直第一显示部101出光面的方向呈一预设夹角。
例如，预设夹角为非零的任意角度，例如可以为45°、60°、90°，优选90°。
可以理解的是，通过设置第一接触面C1、第二接触面C2、第三接触面C3和第四接触面C4均为平面能够进一步降低第一梳齿和第二梳齿相对滑动之间的摩擦阻力。
承上述实施例，如图8~图17a和图17b所示，第一接触面C1、第二接触面C2、第三接触面C3和第四接触面C4均与第一显示部101平行。
具体地，第一梳齿2012和与其相邻的第二梳齿2022中第一接触面C1与第四接触面C4抵接，第二接触面C2和第三接触面C3抵接，在相抵接的接触面上因重力产生相应的支撑力，当接触面（第一接触面C1、第二接触面C2、第三接触面C3和第四接触面C4）倾斜时，重力产生的支撑力会对应的分散，导致第一梳齿2012和第二梳齿2022之间互相支撑的效果减弱。
可以理解的是，设置第一接触面C1、第二接触面C2、第三接触面C3和第四接触面C4均与第一显示部101平行，第一接触面C1与第四接触面C4抵接后，第二接触面C2和第三接触面C3抵接后，其产生的支撑力方向在垂直第一显示部101的方向上，提升第一梳齿2012和第二梳齿2022互相支撑的稳固性。
在一实施例中，如图8~图17a和图17b所示，在垂直第一显示部101的方向上，第一梳齿2012的厚度与第二梳齿2022的厚度相等，第一支撑部2012a和第一止挡部2012b设置于两第一表面所在的平面之间，第二支撑部2022a和第二止挡部2022b设置于两第二表面所在的平面之间。
在实施例中，第一支撑部2012a和第一止挡部2012b的厚度可以相等也可以不等，第二支撑部2022a和第二止挡部2022b的厚度可以相等也可以不等。
可以理解的是，通过设施第一梳齿2012的厚度与第二梳齿2022的厚度相等，第一支撑部2012a和第一止挡部2012b的厚度均小于第一梳齿2012的厚度，第二支撑部2022a和第二止挡部2022b的厚度小于第一梳齿2012的厚度，第一支撑部2012a和第一止挡部2012b设置于两第一表面所在的平面之间，第二支撑部2022a和第二止挡部2022b设置于两第二表面所在的平面之间，在保证第一梳齿2012和第二梳齿2022滑动时具有较小的滑动摩擦力的同时，能够有效的降低支撑组件20的厚度，使得第一梳齿2012和第二梳齿2022的互锁结构不会额外占据过多的空间，避免第一支撑部2012a、第一止挡部2012b、第二支撑部2022a和第二止挡部2022b干涉柔性显示屏10的正常显示，第一梳齿2012和第二梳齿2022的互锁结构设置在两梳齿的侧面，使得柔性显示装置中支撑组件20的体积占比低，进而提高柔性显示装置的整机续航能力。
承上述实施例，如图17a和图17b所示，在第一梳齿2012上，第一主体部2012c包括朝向第一显示部101的第一上表面、背离第一显示部101的第一下表面，第一支撑部2012a与第一主体部2012c的第一下表面平齐，第一止挡部2012b与第一主体部2012c的第一上表面平齐.
在第二梳齿2022上，第二主体部2022c包括朝向第一显示部101的第二上表面、背离第一显示部101的第二下表面，第二支撑部2022a与第二主体部2022c的第二下表面平齐，第二止挡部2022b与第二主体部2022c的第二上表面平齐；
具体地，设置第一支撑部2012a与第一主体部2012c的第一下表面平齐，第一止挡部2012b与第一主体部2012c的第一上表面平齐，第二支撑部2022a与第二主体部2022c的第二下表面平齐，第二止挡部2022b与第二主体部2022c的第二上表面平齐，能够使得支撑组件20朝向柔性显示屏10的两支撑面具有较高的表面平整度。
需要说明的是，第一支撑部2012a、第一止挡部2012b设置于第一梳齿2012的侧面，第二支撑部2022a和第二止挡部2022b设置于第二梳齿2022的侧面，当第一梳齿2012相对第二梳齿2022滑动，使得支撑组件20展开，支撑组件20远离柔性显示屏10的一侧面上形成的凹槽由于支撑部的填充，相对于现有技中的凹滑槽结构，凹槽的深度更低，因此在支撑组件20上贴设柔性显示屏10后能够缓解用户在触控使用过程中按压的下陷感，有效提升用户的使用体验度。
可以理解的是，采用本实施例的技术方案，使得支撑组件20的厚度更薄，且第一支撑部2012a、第一止挡部2012b设置于第一梳齿2012的侧面，第二支撑部2022a和第二止挡部2022b设置于第二梳齿2022的侧面，也能够缓解侧滑屏显示装置在使用过程中因为支撑结构的表面凹凸不平导致的用户在触控使用过程中按压屏幕产生下陷感，有效提升用户的使用体验度。
在一实施例中，如图17a和图17b所示，第一主体部2012c还包括连接第一上表面和第一接触面C1的第一连接面M1、连接第一下表面和第二接触面C2的第二连接面M2；第二支撑部2022a还包括连接第二下表面和第三接触面C3的第三连接面M3、第二止挡部2022b还包括连接第二上表面和第四接触面C4的第四连接面M4。

具体地，第一钝角A1和第二钝角A2均大于90°且小于180°；第一锐角B1和第二锐角B2均大于0°小于90°，当第一钝角A1为120°时，对应的第二锐角B2的度数为60°，当第二钝角A2为150°时，对应的第一锐角B1的度数为30°。
具体地，第一钝角A1和第二钝角A2的度数可以相同也可以不同，具体不作限制，但是第一钝角A1和第二锐角B2的度数需要互补，第二钝角A2和第一锐角B1的度数需要互补，使得第一连接面M1和第四连接面M4能够相贴合，第二连接面M2和第三连接面M3相贴合。
可以理解的是，通过设置第一连接面M1和第四连接面M4能够相贴合（过盈设置），第二连接面M2和第三连接面M3相贴合（过盈设置），且其贴合面倾斜，使得在连接面（第一连接面M1、第二连接面M2、第三连接面M3和第四连接面M4）上也能够对应产生相应的支撑力，使得相应的第一梳齿2012和第二梳齿2022之间互相支撑的效果更好，具体可以根据实际生产情况调整第一钝角A1、第二钝角A2、第一锐角B1和第二锐角B2的角度进行调整。
如图17a和图17b所示，第二主体部2022c还包括连接第二上表面和第三接触面C3的第五连接面M5、连接第二下表面和第四接触面C4的第六连接面M6；第一支撑部2012a还包括连接第一下表面和第一接触面C1的第七连接面M7，第一止挡部2012b还包括连接第一上表面和第二接触面C2的第八连接面M8。
如图17a所示，第五连接面M5与第二上表面具有第三钝角A3，第六连接面M6与第二下表面具有第四钝角A4，第七连接面M7与第一下表面的夹角为第三锐角B3，第八连接面M8与第一上表面的夹角为第四锐角B4，或
如图17b所示，第五连接面M5与第二上表面具有第三锐角B3，第六连接面M6与第二下表面具有第四锐角B4，第七连接面M7与第一下表面的夹角为第三钝角A3，第八连接面M8与第一上表面的夹角为第四钝角A4；第三钝角A3与第四锐角B4互补，第四钝角A4与第三锐角B3互补。
第三钝角A3和第四钝角A4均大于90°且小于180°；第三锐角B3和第四锐角B4均大于0°小于90°，当第三钝角A3为120°时，对应的第四锐角B4的度数为60°，当第四钝角A4为150°时，对应的第三锐角B3的度数为30°。
具体地，第三钝角A3和第四钝角A4的度数可以相同也可以不同，具体不作限制，但是第三钝角A3和第四锐角B4的度数需要互补，第四钝角A4和第三锐角B3的度数需要互补，使得第五连接面M5和第八连接面M8能够相贴合，第六连接面M6和第七连接面M7相贴合。
可以理解的是，通过设置第五连接面M5和第八连接面M8能够相贴合（过盈设置），第六连接面M6和第七连接面M7相贴合（过盈设置），且其贴合面倾斜，使得在连接面（第五连接面M5、第六连接面M6、第七连接面M7和第八连接面M8）上也能够对应产生相应的支撑力使相应的第一梳齿2012和第二梳齿2022之间互相支撑的效果更好，具体可以根据实际生产情况调整第三钝角A3、第四钝角A4、第三锐角B3和第四锐角B4的角度进行调整。
在一实施例中，第一连接面M1、第二连接面M2、第三连接面M3、第四连接面M4、第五连接面M5、第六连接面M6、第七连接面M7、第八连接面M8均与第一显示部101垂直，第一连接面M1和第四连接面M4间隙设置，第二连接面M2和第三连接面M3间隙设置，第五连接面M5和第八连接面M8面间隙设置，第六连接面M6和第七连接面M7面间隙设置。
可以理解的是，通过设置第一连接面M1、第二连接面M2、第三连接面M3、第四连接面M4、第五连接面M5、第六连接面M6、第七连接面M7、第八连接面M8均与第一显示部101垂直，且相对应的连接面之间间隙设置，使得第一梳齿2012和第二梳齿2022之间仅通过第一接触面C1、第二接触面C2、第三接触面C3和第四接触面C4相抵接设置，使得第一梳齿2012和第二梳齿2022之间的滑动摩擦力最小，第一支撑壳体201和第二支撑壳体202之间的滑动更顺滑。
