Description

柔性显示装置及电子装置 技术领域
本申请涉及显示技术领域，尤其涉及一种柔性显示装置及电子装置。
背景技术
柔性屏相对于传统的显示装置而言，具有可弯折的特性，使得搭载有柔性屏的显示装置更加方便携带。
现有的柔性显示装置将柔性屏固定到薄金属支撑片上，然后在将固定有柔性屏的薄金属支撑片固定到柔性屏的弯折区域的铰链上。然而，现有技术中，柔性屏和薄金属支撑片在铰链所对应的弯折区域不能直接进行刚性固定。若直接进行刚性固定，则柔性屏在展平和弯折状态下容易被拉伸损坏或无法进行弯折。另外，若柔性屏和薄金属支撑片在弯折区域不固定，则柔性屏在弯折和展开的过程中会出现弯折区域的翘起，使柔性屏损坏。
发明内容
鉴于现有技术中存在的上述问题，本申请提供一种可让柔性屏的弯折区更好地贴合到支撑片上的柔性显示装置，以保护柔性屏在弯折和展开时不会拉伸和翘起，避免柔性屏被损坏。
为了实现上述目的，本申请实施方式提供如下技术方案：
第一方面，本申请提供了一种柔性显示装置，包括柔性屏以及第一支撑片，所述柔性屏包括弯折区，所述第一支撑片用于支撑所述柔性屏的弯折区，所述弯折区包括固定区和滑动区，所述弯折区通过弹性胶与所述第一支撑片连接，所述弹性胶相比于所述滑动区更偏向于所述固定区；当所述柔性屏弯折时，所述滑动区朝远离所述固定区的方向相对所述第一支撑片滑动。
第二方面，本申请还提供一种电子装置，包括如上所述的柔性屏显示装置及壳体，所述柔性屏装置收容于所述壳体内。
相较于现有技术，本申请实施方式提供的柔性显示装置及电子装置，通过弹性胶将所述柔性屏的弯折区与所述第一支撑片连接，以使柔性屏的弯折区更好地贴合于第一支撑片，所述弹性胶相比于所述滑动区更偏向于所述固定区；当所述柔性屏弯折时，所述滑动区朝远离所述固定区的方向相对所述第一支撑片滑动，因此可补偿柔性屏在弯折和展开过程中的位移变化而避免因拉伸和翘起造成的失效损坏，且不会出现柔性屏的弯折区与第一支撑片的分离，也即可改善柔性屏出现损坏的问题。

具体实施方式
下面将结合本申请实施方式中的附图，对本申请实施方式中的技术方案进行清楚、完整地描述。
可以理解，这里所用的术语仅是为了描述特定实施方式，并非要限制本申请。在这里使用时，除非上下文另有明确表述，否则单数形式“一”和“该”也旨在包括复数形式。进一步地，当在本说明书中使用时，术语“包括”和/或“包含”表明所述特征、整体、步骤、元件和/或组件的存在，但不排除一个或多个其他特征、整体、步骤、元件、组件和/或其组合的存在或增加。说明书后续描述为实施本申请的较佳实施方式，然所述描述乃以说明本申请的一般原则为目的，并非用以限定本申请的范围。本申请的保护范围当视所附权利要求所界定者为准。
请参阅图1至图3，图1所示所示为本申请第一实施例提供了一种柔性显示装置100，图2所示该柔性显示装置100的剖视图，图3所示为该柔性显示装置100弯折状态下的部分剖视图。该柔性显示装置100包括外壳10、设置于外壳10上的柔性屏30及柔性屏防护机构50。柔性屏防护机构50包括滑动件51、第一支撑片52、以及弹性胶55。柔性屏30包括弯折区301，第一支撑片52用于支撑柔性屏30的弯折区301。弯折区301包括固定区3011和滑动区3012，固定区3011通过弹性胶55与第一支撑片52连接，弹性胶55相比于滑动区3012更偏向于固定区3011。当柔性屏30弯折时，滑动区3012朝远离固定区 3011的方向相对第一支撑片52滑动。
当柔性屏30弯折时，柔性屏30与第一支撑片52在弯折区301相对滑动，弹性胶55在柔性屏30相对第一支撑片52滑动时产生拉伸变形，并产生将柔性屏30与第一支撑片52相向拉动的作用力，从而避免柔性显示屏30在弯折时被拉伸而造成的失效损坏。
在本实施方式中，柔性屏30的弯折区301位于柔性屏30的中间位置。柔性屏30包括第一非弯折区302和第二非弯折区303。第一非弯折区302和第二非弯折区303位于弯折区301正对的两侧。柔性屏30的背面于弯折区301和第二非弯折区303正对的位置处设置有第一支撑片52。第一支撑片52用于支撑位于弯折区301和第二非弯折区303内的柔性屏30。在其他实施方式中，第一支撑片52可仅设置在弯折区301正对的位置处，或设置在柔性屏30的背面与所述弯折区301和第一非弯折区302正对的位置处。
在本实施方式中，柔性屏30包括屏体31及固定贴合于屏体31背面的保护层33。保护层33与第一支撑片52之间于固定区3011对应的位置设置有弹性胶55。与弯折区301的滑动区3012正对的保护层33与第一支撑片52之间滑动贴合，保护层33能防止第一支撑片52磨损屏体31的背面。
在本实施方式中，屏体31的正面是指屏体31的出光面，屏体31的背面是指背朝出光面的侧面。保护层33固定贴合于屏体31的背面。保护层33由弹性较好的材料制成。在一实施方式中，保护层33是液态金属片。可以理解的，在其他实施例中，保护层33可以是固定贴合于屏体31背面的耐磨塑胶片或耐磨橡胶片等。
第一支撑片52固定连接于滑动件51。滑动件51相对于固定区3011更邻近滑动区3012，也即，第一支撑片52与滑动区3012相邻的一侧固定于滑动件51。当柔性屏30弯折时，第一支撑片52驱动滑动件51朝滑动区3012滑动，使第一支撑片52与滑动件51在柔性屏30的弯折方向上的周长与弯折区301的周长相等。在本实施方式中，滑动件51设置在第一支撑片52远离柔性屏30的背面，并支撑部分的第一支撑片52，也即，第一支撑片52与滑动件51在靠近柔性屏30的一侧是位于不同的平面上。在另一实施方式中，滑动件51设置在第一支撑片52邻近滑动区3012的一侧并支撑部分的弯折区301的柔性屏30，也即，第一支撑片52与滑动件51在靠近柔性屏30的一侧是位于同一平面上。在本实施方式中，滑动件51大致呈L型。滑动件51包括滑动部511和自滑动部511朝靠近弯折区301的端部垂直向上延伸的连接部512。滑动部511滑动地收容于外壳10所定义的容纳空间(图未示)内。连接部512连接于第一支撑片52。连接部512远离固定区3011的侧面与第一支撑片52远离固定区3011的侧面位于同一水平面上。如此，连接部512与第一支撑片52在弯折区301与第一非弯折区302之间均形成有间隙，因此柔性屏30在弯折时，滑动件51往滑动区3012的滑动时是会朝间隙滑动，并能够支撑该间隙正对的柔性屏30。
第一支撑件52与柔性屏30的弯折区301正对位置处远离所述柔性屏30的一侧设置有铰链15，铰链15所定义的弯折中心轴A1过固定区3012。连接部512靠近铰链15的侧面在柔性屏30处于展开状态时抵接铰链15。在柔性屏30绕弯折中心轴A1弯折时，滑动件51相对铰链15朝远离铰链15的弯折中心轴A1滑动。
可以理解的，滑动件51设置在铰链15与弯折中心轴A1平行的一侧。具体的，在本 实施方式中，滑动件51设置于铰链15在柔性屏30长度方向的一侧，弹性胶55设置于弯折中心轴A1远离滑动件51的一侧。在本实施方式中，弹性胶55沿垂直于柔性屏30的弯折中心轴A1的方向延伸。任意两相邻的弹性胶55间隔平行设置。可选的，任意两相邻的弹性胶55等间距设置。
可选的，柔性屏防护机构50还包括连接于滑动件51远离第一支撑片52的一侧的弹性件56。弹性件56沿滑动件51的滑动方向延伸。当柔性屏30弯折时，第一支撑片52驱动滑动件51朝滑动区3012滑动，滑动件51的滑动使弹性件56发生弹性形变。弹性件56用于在柔性屏30由弯折状态转变为展开状态时给滑动件51提供弹力，以使滑动件51在由弯折状态转变为展开状态后仍能够复位。当柔性屏30由弯折状态转变为展开状态时，弹性件56恢复弹性形变并驱动滑动件51朝靠近固定区3011的一侧滑动。当柔性屏30由展开状态转变为弯折状态时，滑动件51的滑动使弹性件56发生形变并驱动弹性件56朝远离固定区3011的一侧滑动。
可选的，柔性屏防护机构50还包括设置在柔性屏30的第一非弯折区301的背面的第二支撑片53。第二支撑片53与第一支撑片52之间形成间隙54，以为第一支撑片52相对柔性屏30的保护层33滑动时提供滑动空间。在本实施方式中，第一支撑片52对应弯折区301的区域部分滑动贴合于保护层33，第一支撑片52对应第二非弯折区303的区域刚性贴合于保护层33。第二支撑片53刚性贴合于柔性屏30的保护层33。例如，第二支撑片53通过焊接、胶粘或是其他连接件固定地贴合于柔性屏30的保护层33。
在本实施方式中，第一支撑片52和第二支撑片53均由硬度较高和弹性较好的材料制成，比如钢片。在本实施方式中，第一支撑片52和第二支撑片53均是可弯曲的薄钢片。可选的，第一支撑片52和第二支撑片53的硬度高于柔性屏30保护层33的硬度，以提高整个柔性显示装置100的硬度和强度，进而提高用户的操作体验。
请参见图2，外壳10包括第一框体11、第二框体13及连接于第一框体11与第二框体13之间的铰链15。柔性屏30的弯折区301正对铰链15，也即铰链15设置在外壳10上对应弯折区301的位置处。铰链15具有相对的第一侧和第二侧，第一框体11设置在铰链15的第一侧，第二框体13设置在铰链15的第二侧。
在本实施方式中，第一框体11包括相互卡合的第一盖板111和第二盖板112。第一盖板111和第二盖板112共同围设形成供滑动件51滑动的滑槽113。第一盖板111靠近铰链15的一侧开设有供滑动件51穿过的开口1111。开口1111与间隙54相贯通。在本实施方式中，第二框体13的结构与第一框体11相似，不同的是，第二框体13的第一盖板131和第二盖板132之间未设置滑槽。
在一实施方式中，滑动件51的数量可以为一个，滑动件51可设置在第一框体11的中部，或是横跨第一框体11在柔性屏30宽度方向的正对的两末端上。在另一实施方式中，滑动件51的数量也可以为两个。两滑动件51分别间隔设置在第一框体11在柔性屏30宽度方向的正对的两末端上，以使整个柔性屏30在弯折时受力较均匀，且为柔性显示装置100节省空间。
具体的，当柔性显示装置100弯折时，滑动件51由滑槽113的第一位置P1(也即初 始位置)滑动到第二位置P2，此时连接部512抵顶第一盖板111而与铰链15间隔设置，连接部512抵压弹性件56而使弹性件56发生形变。当柔性显示装置100处于展开状态时，滑动件51由滑槽113的第二位置P2滑动到第一位置P1，此时连接部512抵顶铰链15而与第一盖板111间隔设置，弹性件56恢复形变而抵推连接部512返回至初始位置，也即连接部512与第一盖板111间隔设置。可以理解的，第一位置P1是指滑槽113靠近铰链15的弯折中心轴A1的一端(也即滑动件51的连接部512在柔性屏30展开时靠近第一盖板111的侧面)；第二位置P2是指滑槽113远离铰链15的弯折中心轴A1的一端(也即第一盖板111靠近第一支撑片51的侧面)。如此，第一支撑片52的弯折可驱动滑动件51朝滑动区3012滑动，从而延伸第一支撑片52正对弯折区301的长度，进而可在柔性屏30进行弯折时在弯折方向上对弯折区301进行长度补偿。
铰链15包括相互铰接的若干链条151及滑动地设置在链条151上的若干导滑件152。导滑件152可相对铰链15滑动并穿过铰链15。在本实施例中，铰链15包括4个链条151。可以理解的，铰链15的链条151数量取决于柔性显示装置100可弯折的角度。当柔性显示装置100弯折的角度越大，就需要更多的链条151。
具体的，每一链条151沿其长度方向的两端设置有供导滑件152滑动的导滑槽153，且导滑件152的一端卡持于导滑槽153内。导滑槽153设置于铰链15在柔性屏30宽度方向的正对的两末端上。导滑槽153在链条151上沿柔性显示装置100弯折的方向延伸。导滑槽153为设置在链条151上的通槽。导相邻两导滑件152错位设置。
如图2和图3所示，在第一实施方式中，导滑件152的一端穿过铰链15的导滑槽153而固定于第一支撑片52上，导滑件152的另一端收容在导滑槽153内。如此，第一支撑片52与铰链15滑动地相连，可在柔性屏30进行弯折时在弯折方向上对弯折区301进行长度补偿，从而避免柔性屏30在弯折时被拉伸。具体的，导滑件152包括本体1521、锁固件1522、焊接垫片1523及滑动垫片1524。本体1521大致呈柱状。在本实施方式中，本体1521与锁固件1522相卡合，焊接垫片1523的其中一端焊接于第一支撑片52远离柔性屏30的一侧上，焊接垫片1523的另一端焊接于本体1521上，也即焊接垫片1523固定地设置在本体1521和第一支撑片52之间。在另一实施方式中，导滑件152的焊接垫片1523可以省略，具体的，导滑件152的本体1521固定于第一支撑片52，也即本体1521背离锁固件1522的一端固定于第一支撑片52上。锁固件1522设置在本体1521背离焊接垫片1523的一端，且与导滑槽153相卡持。可以理解的，在本实施方式中，本体1521为螺纹套筒，锁固件1522为与螺纹套筒相配合的螺钉。在其他实施方式中，本体1521为螺柱，锁固件1522为螺母。滑动垫片1524夹设在锁固件1522和本体1521之间。具体的，滑动垫片1524夹设在导滑槽153与锁固件1522之间。
请参见图4，在第二实施方式中，导滑件152的一端穿过铰链15的导滑槽153而固定于柔性屏30的保护层33上，且与铰链15滑动地相连，可在柔性屏30进行弯折时在弯折方向上对弯折区301进行长度补偿，从而避免柔性屏30在弯折时被拉伸。具体的，第一支撑片52a开设有供导滑件152穿过的开孔522a。开孔522a与导滑槽153相贯通，但开孔522a的孔径大于导滑槽153的孔径。具体的，焊接垫片1523收容于开孔522a内，并可 在开孔522a内滑动，也即导滑件152通过焊接垫片1523固定地连接于第一支撑片52a。本体1521收容在导滑槽153内。
请一并参看图2和图3，在本实施方式中，导滑件152在柔性屏30展开状态时位于导滑槽153背离滑动件51的一侧，而导滑件152在柔性屏30弯折状态时位于导滑槽153靠近滑动件51的一侧。当柔性屏30处于弯曲状态时，铰链15与第一支撑片52一同弯曲，第一支撑片52驱动滑动件51朝滑动区3012滑动，并且同时驱动导滑件152朝靠近滑动件51的方向滑动。请参见图4，导滑槽153包括相对的第一侧1531和第二侧1532。其中，所述第一侧1531靠近固定区3011，所述第二侧1532靠近滑动区3012。当柔性屏30弯折时，导滑件152自导滑槽153的第一侧1531滑动到所述导滑槽的第二侧1532。当柔性屏30由弯折状态转变为展开时，导滑件152自导滑槽153的第二侧1532滑动到导滑槽153的第一侧1531。可以理解的，当导滑件152滑动到导滑槽153的第二侧1532时，柔性屏30的弯折角度达到最大；当导滑件152滑动到导滑槽153的第一侧1531时，柔性屏30处于展开状态。如此，第一支撑片52的弯折可驱动第一滑动件51a，第二滑动件51b朝滑动区3012滑动，从而延伸第一支撑片52正对弯折区301的长度，进而可在柔性屏30进行弯折时在弯折方向上对弯折区301进行长度补偿。此外，可避免柔性显示装置100在展开时，由于第一支撑片52与柔性屏30在弯折区301的长度不一致而造成柔性屏30在弯折时被拉伸的问题，进而可改善柔性屏30的出现损坏的问题。
请参见图5，在第三实施方式中，柔性显示装置的结构与第二实施方式的柔性显示装置的结构相似。不同之处在于，第三实施方式的导滑件152a的结构不同于第二实施方式中的导滑件152。
具体的，导滑件152a包括焊接垫片1521a和连接于焊接垫片1521a的卡钩1522a。卡钩1522a大致呈L型。焊接垫片1521a和卡钩1522a共同围设形成卡槽1523a。卡槽1523a朝柔性屏30的弯折方向延伸。导滑槽153靠近第一支撑片52的一端的内壁设置有凸起1533。凸起1533可滑动地收容于卡槽1523a内。卡钩1522a在柔性显示装置100处于展开状态时抵接导滑槽153背离凸起1533的槽壁。卡钩1522a在柔性显示装置100弯折到最大角度时抵顶凸起1533。
请一并参看图6和图7，在本实施方式中，所述第一支撑片52对应固定区3011位置处开设有若干通孔520。柔性屏30的保护层33在与通孔520对应的位置处形成有若干填充槽521。通孔520于填充槽521内设置有弹性胶55，以实现柔性屏30固定区域3011的保护层33连接于第一支撑片52。具体的，在本实施方式中，通孔520的两侧壁与保护层33的背面围设形成填充槽521。每一填充槽521沿柔性屏30的弯折方向延伸。若干填充槽521沿弯折区301的长度方向间隔设置。
在本实施方式中，每一填充槽521内过自动点胶设备点有弹性胶55，即，在保护层33的背面与第一支撑片52的通孔520的内壁之间进行点胶，以使保护层33通过弹性胶55连接于第一支撑片52。
弹性胶55例如是，但不局限于光敏胶(比如紫外光固化胶)、硅胶、单组份或双组份AB胶。在本实施方式中，弹性胶55为光敏胶，也即柔性显示装置100的保护层33与 第一支撑片52之间点胶完成后，弹性胶55通过紫外光照射后能固化，此时，弹性胶55固化成具有弹性的固态胶。
本实施例中，柔性显示装置100的保护层33的背面与第一支撑片52的通孔520的侧面之间通过自动点胶设备点设有弹性胶55，且弹性胶55通过紫外光照射后固化成具有弹性的固态胶，因此，弹性胶55能将保护层33与第一支撑片52粘贴连接在一起，能防止柔性屏30与第一支撑片52分离。
在本实施方式中，填充槽521的横截面大致呈矩形。在其他实施例中，填充槽521的横截面还可以大致呈梯形、圆弧形或不规则图形等，以增大弹性胶55与第一支撑片52的接触面积，从而使弹性胶55与第一支撑片52及保护层33的粘贴更牢固。弹性胶55的横截面可以大致呈三角形、梯形、矩形、T字形或不规则图形等。
请参看图8，图8是本申请第二实施方式中的柔性屏和第一支撑片的部分剖视结构示意图。本申请的柔性屏和第一支撑片的第二实施方式的结构与第一实施方式的结构相似，不同之处在于，在第二实施方式中，具体的，保护层33的背面对应填充槽521开设有定位槽331。定位槽331连通填充槽521。填充槽521大致呈梯形。当通过自动点胶设备对第一支撑片52的通孔520与保护层33的背面之间进行点胶时，定位槽331和填充槽521均填充有弹性胶55。
本实施例中，定位槽331的横截面呈V形，定位槽331能增大弹性胶55与第一支撑片52的接触面积，从而使弹性胶55与第一支撑片52的通孔520及保护层33的背面粘贴更牢固。在其他实施例中，定位槽331的横截面可以呈矩形、圆弧形或不规则图形等。
请参看图9，图9是本申请第三实施方式中的柔性屏和第一支撑片的部分剖视结构示意图。本申请的柔性屏和第一支撑片的第三实施方式的结构与第一实施方式的结构相似，不同之处在于，在第三实施方式中，保护层33靠近第一支撑片52的一侧开设有若干定位槽332，定位槽332对应弯折区301。定位槽332连通填充槽521。定位槽332的一侧对应第一支撑片52的背面，定位槽5124的另一侧连通填充槽521。定位槽332沿填充槽521的长度方向延伸。当柔性显示装置100的保护层33的背面与第一支撑片52的通孔520之间通过自动点胶设备点有弹性胶55时，定位槽332内也填充有弹性胶55，此时第一支撑片52的侧面与正面均填充有弹性胶55，即，保护层33的侧面与第一支撑片52之间均设置有弹性胶55。
本实施例中，定位槽332的横截面呈半圆形，定位槽332能增大弹性胶55与第一支撑片52及保护层33的接触面积，从而使弹性胶55与第一支撑片52及保护层33的粘贴更牢固、更密封。
在其他实施例中，定位槽332的横截面可以是矩形、V形或不规则图形等。
请参阅图10，图10是本申请第四实施例中的柔性显示装置的部分剖视结构示意图。本申请柔性显示装置的第四实施例的结构与第一实施例的结构相似，不同之处在于，第四实施例中，弹性胶55的横截面呈三角形，也即弹性胶55涂覆于保护层33的背面及第一支撑片52的通孔520的其中一个侧面。
本实施例中，弹性胶55是通过侧面点胶的方式注入填充槽521内，使得上述各层能 相互粘接。在其他实施例中，弹性胶55的横截面可以是矩形等，只需弹性胶55一并涂设于保护层33的背面及第一支撑片52的侧面上即可。
本申请实施方式提供的柔性显示装置，通过将弹性胶将弯折区与第一支撑片连接在一起，所述弹性胶相比于所述滑动区更偏向于所述固定区；当所述柔性屏弯折时，所述滑动区朝远离所述固定区的方向相对所述第一支撑片滑动，以补偿柔性屏在弯折和展开过程中的单向位移变化而避免因拉伸造成的失效损坏，进而不会出现柔性屏的弯折区与铰链的分离，也即可改善柔性屏出现损坏的问题。此外，在柔性显示装置弯曲时，通过第一支撑片的弯曲驱动滑动件及导滑件朝滑动区滑动，以使铰链与第一支撑片发生变形，且使得铰链与第一支撑片一同弯曲。由于铰链是和第一支撑片一同弯曲，可避免第一支撑片不受控的单独发生弯曲，从而避免柔性屏的翘起，进而防止或减轻柔性屏损坏的问题。
请一并参阅图11至图13，图11是本申请第二实施例中的柔性显示装置的结构示意图。本申请柔性显示装置的第二实施例的结构与第一实施例的结构相似，不同之处在于，在第二实施例中，柔性显示装置200包括第一滑动件51a、第二滑动件51b、两弹性件56及两第二支撑片53。第一支撑片52间隔地设置在两第二支撑片53之间，且对应弯折区301。第一滑动件51a和第二滑动件51b分别设置在铰链15与弯折中轴A1平行的两侧，也即设置在弯折区301的左右两侧。第一滑动件51a和第二滑动件51b分别固定地连接于第一支撑片52的两末端上。弹性胶55a设置在柔性屏30和第一支撑片52之间，且设置在弯折区301所对应的中间位置。每一弹性件56连接于对应的滑动件51。导滑件152a相对铰链15的弯折中心轴A1相向地设置在对应的链条151上，导滑件152a在柔性屏30弯折时朝背离铰链15的弯折中心轴A1的一侧滑动。
在本实施方式中，弯折区301包括一固定区3011与两滑动区3012，固定区3011位于弯折区301的中间位置，滑动区3012各自位于固定区3011的正对的两侧。在本实施例中，弹性胶55a并排设置在固定区3011。弹性胶55沿垂直于柔性屏30的弯折中心轴A1的方向延伸。任意两相邻的弹性胶55间隔平行设置。可选的，任意两相邻的弹性胶55等间距设置。弹性胶55a相对铰链15的弯折中心轴A1对称地设置。
弹性胶55a沿柔性屏30的弯折方向延伸，也即弹性胶55a沿垂直于柔性屏30的弯折中心轴A1的方向延伸。任意两相邻的弹性胶55a间隔平行设置。可选的，任意两相邻的弹性胶55a等间距设置，以使柔性屏30在弯折或展开时受力均衡，从而避免柔性屏30的显示器件因拉伸而导致器件损坏。弹性胶55a设置在每一链条151上的两相对的导滑件152之间。
第一滑动件51b滑动地设置在第一框体11上。在本实施方式中，第一框体11的结构与第一实施例中的第一框体11的结构相同，在此不再赘述。第二框体13的结构与第一框体11的结构相同。第二框体13包括相互卡合的第一盖板131和第二盖板132。第一盖板131和第二盖板132共同围设形成供第二滑动件51b滑动的滑槽133。第一盖板131靠近铰链15的一侧开设供第二滑动件51b的连接部512b穿过的开口1311。
在本实施例中，第二实施例中的第一滑动件51a和第二滑动件51b的结构与第一实施例中的滑动件51的结构一致，在此不再赘述。如图13所示，第一滑动件51a和第二滑动 件51b分别设置在外壳10在铰链15在柔性屏30长度方向的相对的两侧，弹性胶55a设置在铰链15的弯折中心轴A1所对应的位置。第一滑动件51a和第二滑动件51b相对铰链15的弯折中心轴A1对称地设置。第一滑动件51a和第二滑动件51b在柔性屏30弯曲时朝背离铰链15的弯折中心轴A1滑动，也即两滑动件51的运动方向相反。铰链15的相对两侧受力时，铰链15与第一支撑片52一同弯曲，第一支撑片52驱动第一滑动件51a和第二滑动件51b分别朝对应的滑动区3012滑动，并且同时驱动导滑件152a朝靠近滑动件51的方向滑动，以补偿柔性屏在弯折和展开过程中的双向位移变化而避免因拉伸造成的失效损坏，进而不会出现柔性屏的弯折区与铰链的分离，也即可改善柔性屏出现损坏的问题。
在本实施方式中，第一滑动件51a由滑槽113的第一位置P1滑动到第二位置P2，第二滑动件51b由滑槽133由滑槽113的第一位置P1滑动到第二位置P2。第一位置P1是指滑槽113，133靠近弯折中心轴A1的一端，第二位置P2是指滑槽113，133远离弯折中心轴A1的一端。当柔性屏30弯折时，导滑件152a背离铰链15的弯折中心轴A1一侧滑动。具体的，导滑件152a由导滑槽153的第三位置P3滑动到第四位置P4。第三位置P3是指导滑槽153靠近铰链15的弯折中心轴A1的一端(也即滑槽153背离凸起1533的槽壁)，第四位置P4是指导滑槽153远离铰链15的弯折中心轴A1的一端(也即卡钩1522a的自由端)。如此，第一支撑片52的弯折可驱动导滑件152、第一滑动件51a及第二滑动件51b朝滑动区3012滑动，从而延伸第一支撑片52正对弯折区301的长度，进而可在柔性屏30进行弯折时在弯折方向上对弯折区301进行长度补偿。此外，可避免柔性显示装置100在展开时，由于第一支撑片52与柔性屏30在弯折区301的长度不一致而造成柔性屏30在弯折时被拉伸的问题，进而可改善柔性屏30的出现损坏的问题。
可以理解的，第一实施例所述的第一支撑片52，52a的结构设计、导滑件152，152a的结构设计、以及填充槽521的结构设计均适用于第二实施例的柔性显示装置200，在此不再赘述。
本申请实施方式提供的柔性显示装置，通过在弯折区的两外围边缘分别设置有第一滑动件和第二滑动件，第一滑动件和第二滑动件分别固定连接于第一支撑片的两端，而第一支撑片通过弹性胶滑动贴合于柔性屏，从而第一支撑片能够在柔性屏弯折时驱动第一滑动件和第二滑动件在两弯折区相向滑动，弹性胶在柔性屏相对第一支撑片滑动时产生拉伸变形，以补偿柔性屏在弯折和展开过程中的双向位移变化而避免因拉伸造成的失效损坏，进而不会出现柔性屏的弯折区与铰链的分离，也即可改善柔性屏出现损坏的问题。此外，在柔性显示装置弯曲时，通过第一支撑片的弯折可驱动导滑件、第一滑动件及第二滑动件朝滑动区滑动，且使得铰链与第一支撑片一同弯曲。由于铰链是和第一支撑片一同弯曲，可避免第一支撑片不受控的单独发生弯曲，从而避免柔性屏的翘起，进而防止或减轻柔性屏损坏的问题。
如图14所示，在本实施方式中，所示为本申请实施例提供了一种电子装置1000。电子装置1000包括第一实施例和第二实施例所述的柔性屏显示装置100，200及壳体300，所述柔性屏装置100，200收容于所述壳体300内。
电子装置1000为手机。可以理解的，电子装置1000还可以是，但不局限于平板电脑、 显示器、液晶面板、OLEP面板、电视、智慧手表、VR头戴显示器、车载显示器等其它任何具有显示功能的产品和部件。
以上对本申请实施方式进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施方式的说明只是用于帮助理解本申请的方法及其核心思想；同时，对于本领域的一般技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上上述，本说明书内容不应理解为对本申请的限制。
