具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
请一并参阅图1至图4，本申请实施例提供的柔性显示设备100包括刚性部分10和柔性显示部分20，刚性部分10与柔性显示部分20转动连接，一种实施方式中，刚性部分10与柔性显示部分20相互铰接，从而使刚性部分10与柔性显示部分20可以相对转动。本实施例中，刚性部分10不易弯折，结合图5，刚性部分10内设电路板18，刚性部分10保护电路板18，避免电路板18受到弯折后发生折断等情况。本实施例中，刚性部分10为中空的长方体形状，并且刚性部分10的厚度尺寸相对于刚性部分10的长度尺寸和宽度尺寸较小，刚性部分10也可以为片状结构。进一步的，柔性显示部分20具有柔性可弯折的特点，具体的，柔性显示部分20用于显示图像，结合图5，柔性显示部分20与刚性部分10内的电路板18电连接，从而使电路板18可以驱动柔性显示部分20显示图像，一种实施方式中，柔性显示部分20与电路板18通过柔性电路板电连接，其他实施方式中，柔性显示部分20与电路板18也可以通过通电导线电连接。柔性显示部分20包括用于显示图像的显示面200，柔性显示部分20弯曲时，柔性显示部分20向背离显示面200的一侧弯折，换言之，柔性显示部分20弯折成环状时，显示面200始终朝向外侧，以向外显示图像。进一步的，柔性显示部分20展开时，柔性显示部分20为长方体形状，并且柔性显示部分20的厚度尺寸相对于柔性显示部分20的长度尺寸和宽度尺寸较小，柔性显示部分20也可以为片状结构，显然的，柔性显示部分20的厚度越小，柔性显示部分20弯折的效果越好。具体到图1，图1所示为展开状态的柔性显示设备100，柔性显示部分20显示图像，刚性部分10位于柔性显示部分20的一侧，并驱动柔性显示部分20显示图像，一种实施方式中，柔性显示部分20的一侧表面均为显示面200，换言之，柔性显示部分20的一侧表面全部可以显示图像，走线、电路板18等均设置于刚性部分10内。具体到图3，图3所示为卷绕状态的柔性显示设备100，柔性显示设备100卷绕时，柔性显示部分20与刚性部分10首尾相连形成圆筒状的结构，结合图4，图4为卷绕状态的柔性显示设备100的侧视图，卷绕状态的柔性显示设备100的侧面为圆 环状。进一步的，柔性显示设备100的显示面200面向圆筒的外侧，从而使柔性显示设备100向周围接近360度方向显示图像。一种实施方式中，减小刚性部分10的尺寸，增大柔性显示部分20的尺寸，可以提高柔性显示设备100的显示范围，换言之，减小刚性部分10的尺寸，增大柔性显示部分20的尺寸，柔性显示设备100的显示范围越接近360度。
柔性显示设备100具有展开状态和卷绕状态两种显示模式，显示模式多样，进一步的，卷绕状态时，刚性部分10不弯折，以保护刚性部分10内部的电路板18，柔性显示部分20弯折以形成圆筒状的显示面200，柔性显示设备100在展开状态和卷绕状态之间切换，柔性显示设备100的显示模式灵活多变，提高了用户体验。
结合图5，图5所示为柔性显示设备100的部分结构放大示意图，具体的，图5所示为柔性显示设备100的刚性部分10及刚性部分10与柔性显示部分20的连接处的结构示意图。本实施例中，柔性显示部分20包括相对设置的第一端242与第二端244，进一步的，第一端242和第二端244位于柔性显示部分20的长度方向上，即柔性显示部分20可弯折的方向上。第一端242与刚性部分10的一端转动连接，一种实施方式中，第一端242与刚性部分10的一端铰接，从而使刚性部分10可以与柔性显示部分20相对弯折，第二端244设有第一连接件32，刚性部分10远离第一端242的一端设有与第一连接件32相配合的第二连接件34，当第一连接件32与第二连接件34连接时，刚性部分10与柔性显示部分20首尾相连形成环状结构。一种实施方式中，第一连接件32和第二连接件34为相互配合的锁紧件，例如卡扣等结构，其他实施方式中，第一连接件32和第二连接件34为相互配合的磁性件等可以相互固定且可以相互分离的结构。进一步的，结合图4，当第一连接件32与第二连接件34连接时，柔性显示部分20卷绕形成弧形的结构，柔性显示部分20的第一端242和第二端244分别连接于刚性部分10的两端，从而使柔性显示部分20与刚性部分10连接形成封闭的环形。一种实施方式中，柔性显示部分20各位置弯曲的弧度相同，换言之，柔性显示部分20卷绕后形成圆弧。
柔性显示设备100具有展开状态和卷绕状态两种显示模式，显示模式多样，进一步的，卷绕状态时，刚性部分10不弯折，以保护刚性部分10内部的电路板 18，柔性显示部分20弯折以形成圆筒状的显示面200，柔性显示部分20一端与刚性部分10转动连接，连接方式简单，柔性显示部分20另一端与刚性部分10通过第一连接件32和第二连接件34连接，连接紧固，且可拆卸，有利于柔性显示设备100在展开状态和卷绕状态之间切换，柔性显示设备100的显示模式灵活多变，提高了用户体验。
一种实施方式中，第一连接件32为挂钩，第二连接件34为扣环，挂钩与扣环的搭配容易扣合，也容易拆卸，扣合效果好，且使用寿命长。一种实施方式中，如图1所示，第一连接件32的数量和第二连接件34的数量可以为多个，且第一连接件32的数量和第二连接件34的数量相等，第一连接件32均匀的分布在柔性显示部分20的第二端244，对应的，第二连接件34均匀的分布在刚性部分10远离第一端242的一端，从而加强第一连接件32的数量和第二连接件34的锁紧效果，提高卷绕状态的柔性显示设备100的结构稳定性。
请参阅图2和图6，本实施例中，柔性显示部分20包括柔性背板220和固定于柔性背板220上的柔性显示面板，柔性背板220与刚性部分10转动连接，柔性显示面板电连接电路板18以显示图像。具体的，柔性背板220为柔性显示部分20的支撑板，柔性背板220具有柔性可弯折的特点，且柔性背板220不易断裂，以保持柔性显示部分20整体结构的稳定性。柔性显示面板也具有柔性可弯折的特点，柔性显示面板通过粘贴等方式固定于柔性背板220上，并且柔性显示面板与柔性背板220可以一同弯折。本实施例中，柔性背板220与刚性部分10转动连接，从而实现柔性显示部分20与刚性部分10的转动连接，进一步的，柔性背板220的一端与刚性部分10转动连接，即柔性背板220对应柔性显示部分20的第一端242的一端与刚性部分10转动连接。以柔性背板220作为柔性显示部分20的基板，并仅使用柔性背板220与刚性部分10直接连接，当柔性显示面板等组件损坏时，可以仅从柔性背板220上拆除柔性显示面板，而无需将柔性显示部分20与刚性部分10分离，简化维修过程，节约产品维护成本。进一步的，相较于柔性显示面板与刚性部分10转动连接，柔性背板220的结构简单且材料成本较低，若连接处弯折次数过多而出现损坏时，更换柔性背板220的维护成本更低，当然，相较于柔性显示面板，柔性背板220的耐磨损能力也更强。
请继续参阅图2和图6，本实施例中，柔性显示设备100还包括转动连接的 第一支撑板122和第二支撑板124，电路板18固定于第一支撑板122上，柔性背板220包括相对设置的第一侧面220a与第二侧面220b，第一侧面220a至少部分贴合于第二支撑板124上，柔性显示面板设置于第二侧面220b上。具体的，第一支撑板122和第二支撑板124为刚性、不易弯折的支撑板，一种实施方式中，第一支撑板122和第二支撑板124为钢片。第一支撑板122固定于刚性部分10上，也可以理解为，第一支撑板122为刚性部分10的基板，保持刚性部分10的刚性强度，电路板18设置于第一支撑板122上，从而在第一支撑板122的保护下，电路板18不会受到弯折的力的作用，从而保证电路板18的长期使用。柔性背板220的第一侧面220a贴合在第二支撑板124上，具体的，柔性背板220靠近第一端242的端部贴合在第二支撑板124上，第二支撑板124仅支撑柔性背板220靠近第一端242的端部，从而使柔性背板220靠近第一端242的端部不易弯折，以使柔性显示部分20在第一端242位置处的柔性显示面板等结构不发生弯折。进一步的，柔性背板220未贴合第二支撑板124的部分没有收到第二支撑板124的约束，可以发生弯折并卷绕。本实施例中，柔性显示面板设置于第二侧面220b上，第二支撑板124使柔性显示部分20的第一端242处不可弯折，从而保护第一端242内部的器件不会因为弯折而被破坏。
具体的，柔性显示面板包括背光源222、导光板224及液晶面板226，导光板224和液晶面板226依次层叠设置于柔性背板220上，背光源222位于柔性背板220上，且背光源222位于导光板224靠近刚性部分10的一侧，导光板224用于将背光源222发出的光线导向液晶面板226以显示图像，背光源222在柔性背板220的垂直投影落在第二支撑板124的范围内，导光板224在柔性背板220的垂直投影与第二支撑板124相交。本实施例中，背光源222为侧入式导光结构，换言之，背光源222从导光板224的一侧向导光板224内射入背光光线，通过导光板224的导光效果，背光光线在导光板224内的传播方向偏转约90度后从导光板224面对液晶面板226的一侧射出，从而使背光光线穿过液晶面板226，液晶面板226显示图像。一种实施方式中，柔性显示面板中还设有反射片、扩散片等结构用于改善光路效果。本实施例中，背光源222在柔性背板220的垂直投影落在第二支撑板124的范围内，导光板224在柔性背板220的垂直投影与第二支撑板124相交，换言之，第二支撑板124支撑背光源222和导光板224面对背光源222的一 端，导光板224面对背光源222的一端不发生弯折，背光源222与导光板224的距离不变，背光源222向导光板224的偶光质量不会受到影响，柔性显示面板显示图像的亮度和效果较佳，无论柔性显示设备100处于展开状态还是卷绕状态，柔性显示显示面板的显示效果不受影响。
请继续参阅图2和图6，本实施例中，柔性显示设备100还包括百褶连接盖40，百褶连接盖40连接于刚性部分10与柔性显示部分20之间，百褶连接盖40对应第一支撑板122与第二支撑板124的连接处。具体的，百褶连接盖40位于刚性部分10与柔性显示部分20的连接处，即百褶连接盖40对应刚性部分10与柔性显示部分20的连接位置。进一步的，百褶连接盖40用于形成柔性显示设备100的部分外观。具体到图2，当柔性显示设备100处于展开状态时，刚性部分10与柔性显示部分20处于一条直线上，百褶连接盖40处于折叠的状态，百褶连接盖40遮盖刚性部分10与柔性显示部分20的连接处，百褶连接盖40占用的空间小；具体到图6，当柔性显示设备100处于卷绕状态时，刚性部分10与柔性显示部分20相对弯折，即刚性部分10与柔性显示部分20之间形成夹角，一种实施方式中，刚性部分10与柔性显示部分20之间形成夹角的角度为90度，此时百褶连接盖40处于伸展的状态，百褶连接盖40伸展成为平整的表面，百褶连接盖40依然遮盖刚性部分10与柔性显示部分20的连接处。由于刚性部分10与柔性显示部分20相对弯折时，百褶连接盖40位置为弯折半径最大的位置，百褶连接盖40的长度可以压缩或伸长，百褶连接盖40压缩时不占用过多空间，百褶连接盖40伸长时不会因为被过度拉伸而易折断，换言之，百褶连接盖40可以满足柔性显示设备100在展开状态和卷绕状态的使用要求，提高柔性显示设备100的结构稳定性。
请参阅图2，本实施例中，刚性部分10包括前框14和侧框16，前框14与第一支撑板122相对设置，电路板18收容于前框14、侧框16及第一支撑板122形成的收容空间内，进一步的，前框14、侧框16及第一支撑板122均为刚性结构，不易弯折，电路板18收容于该收容空间内可以得到很好的保护，不会因为受到外力而弯折或折断。本实施例中，柔性显示部分20还包括透明盖板228，透明盖板228位于柔性显示面板背离柔性背板220的一侧，透明盖板228贴合于液晶面板226的表面上，起到保护液晶面板226的作用，防止液晶面板226被刮伤。请继续参阅图2，本实施例中，百褶连接盖40的一端固定于前框14上，另一端 固定于透明盖板228上，具体的，百褶连接盖40包括第一连接段42、第二连接段44及折叠段46，折叠段46位于第一连接段42与第二连接段44之间，第一连接段42固定连接前框14，从而使百褶连接盖40与刚性部分10固定连接，第二连接段44固定连接透明盖板228，从而使百褶连接盖40与柔性显示部分20固定连接，卷绕柔性显示设备100时，刚性部分10通过第一连接段42拉伸折叠段46，柔性显示部分20通过第二连接段44拉伸折叠段46，展开柔性显示设备100时，刚性部分10通过第一连接段42压缩折叠段46，柔性显示部分20通过第二连接段44压缩折叠段46。
请继续参阅图2，本实施例中，当柔性显示设备100处于展开状态时，前框14与透明盖板228齐平，百褶连接盖40一端贴合于前框14面对第一支撑板122的一侧，另一端贴合于透明盖板228背离第二支撑板124的一侧，具体的，百褶连接盖40的第一连接段42贴合于前框14面对第一支撑板122的一侧，百褶连接盖40的第二连接段44贴合于透明盖板228背离第二支撑板124的一侧，可以提高百褶连接盖40与刚性部分10及柔性显示部分20的连接强度，避免多次卷绕和展开柔性显示设备100后百褶连接盖40脱落。
请继续参阅图2，本实施例中，第一连接件32固定于柔性背板220上，第二连接件34固定于侧框16上。柔性背板220为柔性显示部分20的基板，当第一连接件32与第二连接件34锁紧时，第一连接件32与第二支撑板124从柔性背板220的两端拉伸柔性背板220，而柔性背板220上的导光板224、液晶面板226等器件不受到拉伸力的影响，柔性显示部分20的结构稳定，不易被损坏。第二连接件34固定于侧框16上，即第二连接件34固定连接至第一支撑板122与前框14，第二连接件34牢固而不易从刚性部分10脱落，提高了柔性显示设备100处于卷绕状态时的结构稳定性。
一种实施方式中，刚性部分10的厚度与柔性显示部分20的厚度相同，从而当柔性显示设备100处于展开状态时，柔性显示设备100的一体化效果更佳，提高用户体验。
柔性显示设备100具有展开状态和卷绕状态两种显示模式，显示模式多样，进一步的，卷绕状态时，刚性部分10不弯折，以保护刚性部分10内部的电路板18，柔性显示部分20弯折以形成圆筒状的显示面200，柔性显示部分20一端与 刚性部分10转动连接，连接方式简单，柔性显示部分20另一端与刚性部分10通过第一连接件32和第二连接件34连接，连接紧固，且可拆卸，有利于柔性显示设备100在展开状态和卷绕状态之间切换，柔性显示设备100的显示模式灵活多变，提高了用户体验。
以上所揭露的仅为本申请几种较佳实施例而已，当然不能以此来限定本申请之权利范围，本领域普通技术人员可以理解实现上述实施例的全部或部分流程，并依本申请权利要求所作的等同变化，仍属于申请所涵盖的范围。
