技术领域
本申请涉及显示设备技术领域，尤其涉及一种显示装置及移动终端。
背景技术
随着电子产品的更新换代，为了带来更好的使用体验，各种电子设备终端，如手机、平板电脑等的显示屏幕变得越来越大。但是，随着屏幕的增大，电子设备的外形尺寸也会相应地增大，会带来携带、存放不方便的问题。
折叠手机的设计满足了消费者追求便携式大屏的需求。因此，柔性折叠屏被认为是未来手机的发展形态。柔性折叠屏技术很好的找到了电子设备的小型化发展与显示屏幕的大屏化发展的折中点，比如折叠屏手机在折叠后跟常规手机大小一样，可以很方便的携带；而当把屏幕展开，则可以获得一块显示面积较大的屏幕。另外，柔性屏能很大程度实现自由弯曲，使得智能终端设备摆脱现有的刚性结构，实现形式的多样化构造，实现智能终端设备屏幕的折叠弯曲。
但是目前的折叠产品在从折叠状态到展平状态时，展平状态的折叠产品屏体存在轻微褶皱的外观问题，影响客户的观感和产品寿命。
发明内容
本申请提供一种显示装置及移动终端，旨在解决折叠产品外观效果差的问题。
本申请第一方面的实施例提供了一种显示装置，包括：柔性显示面板，包括固定部及位于相邻两个固定部之间的可弯折部；支撑组件，包括两个支撑部，两个支撑部分别设置于两个固定部的表面以支撑柔性显示面板；转轴，位于两个所述支撑部之间并对应于可弯折部设置；滑动组件，包括在垂直于转轴的方向上可滑动连接的第一滑件和第二滑件，第一滑件连接于支撑部，第二滑件可转动地连接于转轴；驱动组件，包括第一磁性件和第二磁性件，第一磁性件和第二磁性件之间的磁力向第一滑件提供沿远离转轴的方向移动的驱动力。
本申请第二方面的实施例还提供了一种移动终端，包括上述的显示装置。
在本申请实施例的显示装置中，显示装置包括柔性显示面板、支撑组件、滑动组件和驱动组件。柔性显示面板通过其可弯折部能够实现显示装置在折叠状态至展平状态之间的转变，支撑组件的支撑部能够向柔性显示面板的固定部提供良好的支撑，转轴能够保证可弯折部实现正常弯折。滑动组件中的第一滑件和第二滑件相互可滑动设置，使得显示装置在弯折时，第一滑件能够带动支撑部相对转轴移动。驱动组件中第一磁性件和第二磁性件会产生磁力，该磁力驱动第一滑件向远离转轴的方向移动，使得第一滑件能够带动支撑部远离转轴，进而带动固定部远离转轴，能够使得固定部尽可能的远离弯折部，从而将可弯折部拉伸至平展状态。因此本申请实施例的显示装置能够解决现有技术中折叠产品在展平状态存在褶皱的问题，使得折叠产品具有良好的观感，并能够避免由于褶皱对柔性屏使用寿命的影响，提高柔性显示面板的使用寿命。

具体实施方式
为了更好地理解本申请，下面结合图1至图5对本申请实施例的显示装置及移动终端进行详细描述。
请一并参阅图1至图3，本申请实施例的显示装置包括：柔性显示面板100，包括相邻的两个固定部110及位于相邻两个固定部110之间的可弯折部120；支撑组件200，包括两个支撑部210，两个支撑部210分别设置于两个固定部110的表面以支撑柔性显示面板100；转轴220，位于两个支撑部210之间并对应于可弯折部120设置；滑动组件300，包括在垂直于转轴220的方向(即图1中的X方向)上可滑动连接的第一滑件310和第二滑件320，第一滑件310连接于支撑部210，第二滑件320可转动地连接于转轴220；驱动组件400，包括第一磁性件410和第二磁性件420，第一磁性件410和第二磁性件420之间的磁力向第一滑件310提供远离转轴220的方向移动的驱动力。
根据本申请的实施例，对于显示装置的具体类型没有限制。显示装置的示例可以，但不限于，可折叠手机的显示屏，或者可折叠平板电脑的显示屏等。
图1中以虚线示出固定部110和可弯折部120之间的界限，虚线并不构成对柔性显示面板100结构的限定，固定部110和可弯折部120可以为一体式设置。
在本申请实施例的显示装置中，显示装置包括柔性显示面板100、支撑组件200、滑动组件300和驱动组件400。柔性显示面板100通过其可弯折部120能够实现显示装置在折叠状态至展平状态之间的转变，支撑组 件200的支撑部210能够向柔性显示面板100的固定部110提供良好的支撑，转轴220能够保证可弯折部120实现正常弯折。滑动组件300中的第一滑件310和第二滑件320相互可滑动设置，使得显示装置在弯折时，第一滑件310能够带动支撑部210相对转轴220移动。驱动组件400中第一磁性件410和第二磁性件420会产生磁力，该磁力驱动第一滑件310向远离转轴220的方向移动，使得第一滑件310能够带动支撑部210远离转轴220，进而带动固定部110远离转轴220，能够使得固定部110尽可能的远离可弯折部120，从而将可弯折部120拉伸至平展状态。因此本申请实施例的显示装置能够解决现有技术中折叠产品在展平状态存在褶皱的问题，使得折叠产品具有良好的观感，并能够避免由于褶皱对柔性屏使用寿命的影响，提高柔性显示面板100的使用寿命。
在一些可选的实施例中，柔性显示面板100和支撑组件200之间设置有保护层130，支撑部210通过保护层130连接于固定部110。避免支撑部210带动固定部110移动时对固定部110造成损伤，进一步提高显示装置的使用寿命。保护层130例如可以为柔性金属板等。
在一些可选的实施例中，显示装置具有折叠状态和展平状态，在展平状态下第一磁性件410和第二磁性件420之间的磁力向第一滑件310提供远离转轴220方向移动的驱动力。
当显示装置为内折式显示装置，即在折叠状态下柔性显示面板100位于支撑组件200的内侧，在折叠状态下用户无法观察到柔性显示面板100，因此内折式显示装置在折叠状态下无需柔性显示面板100进行显示。但是内折式显示装置在展平状态，可弯折部120易出现凹陷等问题。本申请实施例的显示装置在展平状态下，第一磁性件410和第二磁性件420之间的磁力向第一滑件310提供远离转轴220方向移动的驱动力。因此在展平状态下，第一滑件310能够带动支撑部210及固定部110沿远离转轴220的方向移动，进而能够提高可弯折部120的平整度。
如图4和图5所示，图4和图5所示的显示装置为外折式显示装置，图5中为了更好的展示显示装置的内部结构，将支撑组件200外侧的柔性显示面板100及保护层130等结构去除。当显示装置为外折式显示装置， 即在折叠状态下柔性显示面板100位于支撑组件200的外侧，在折叠状态下用户依然可以观察到柔性显示面板100。外折式显示装置在折叠状态时，柔性显示面板100处于拉伸状态，不易出现褶皱问题。但是外折式显示装置在展平状态下，可弯折部120易出现鼓包等问题。本申请实施例的显示装置在展平状态下，第一磁性件410和第二磁性件420之间的磁力向第一滑件310提供远离转轴220方向移动的驱动力。因此在展平状态下第一滑件310能够带动支撑部210及固定部110沿远离转轴220的方向移动，进而能够提高可弯折部120的平整度。
第一磁性件410和第二磁性件420之间磁力的设置方式有多种，例如可以利用第一磁性件410和第二磁性件420之间产生的磁性吸力作为上述的驱动力。这时第一磁性件410和第二磁性件420的磁性相异，在展平状态下第一磁性件410和第二磁性件420之间的距离在预设距离范围之内，使得第一磁性件410和第二磁性件420之间的磁性吸力能够向第一滑件310提供沿远离转轴220的方向移动的驱动力。
预设距离范围的具体取值有多种，用户可以根据第一磁性件410和第二磁性件420所具有的磁场的强度或者显示装置内预留的尺寸空间等进行设定，只要当第一磁性件410和第二磁性件420之间的距离在预设距离范围之内时，使得第一磁性件410和第二磁性件420之间产生的磁性吸力能够驱动第一滑件310沿远离转轴220的方向移动即可。例如预设距离范围为2mm～6mm等。
当第一磁性件410和第二磁性件420的磁性相异时，在展平状态下，第二磁性件420位于第一磁性件410背离转轴220的一侧，使得第一磁性件410和第二磁性件420之间的磁性吸力可以驱动第一磁性件410沿远离转轴220的方向移动，进而提高可弯折部120的平整度。
或者，在另一些可选的实施例中，可以利用第一磁性件410和第二磁性件420产生的磁性斥力作为上述的驱动力。这时，第一磁性件410和第二磁性件420的磁性相同，在展平状态下第一磁性件410和第二磁性件420之间的距离小于或等于第一距离阈值，使得第一磁性件410和第二磁性件420之间的磁性斥力能够驱动第一滑件310沿远离转轴220的方向移 动。且当第一磁性件410和第二磁性件420之间的磁性斥力作为驱动力时，由于第一磁性件410和第二磁性件420的磁性相同，即使显示装置内设置有多组滑动组件300和驱动组件400，各驱动组件400之间的磁性力不会相互干扰，保证各驱动组件400的正常稳定运行。
第一距离阈值的具体取值有多种，第一距离阈值可以根据第一磁性件410和第二磁性件420磁场强度和显示装置内预留的空间尺寸等参数进行设定，只要第一磁性件410和第二磁性件420之间的距离小于或等于第一距离阈值时，第一磁性件410和第二磁性件420之间的磁性斥力足以驱动第一滑件310沿远离转轴220的方向移动即可。例如，第一阈值为50μm～3mm等。
当第一磁性件410和第二磁性件320的磁性相同，在展平状态下第二磁性件420位于第一磁性件410朝向转轴220的一侧。使得第二磁性件420和第一磁性件410之间的磁性斥力能够驱动第一磁性件410沿远离转轴220的方向移动，进而提高可弯折部120的平整度。例如，第二磁性件420位于第一磁性件410和转轴220之间；或者转轴220位于第二磁性件420和第一磁性件410之间，即第二磁性件420位于转轴220背离第一磁性件410的一侧。
下面以第一磁性件410和第二磁性件420的磁性相同作为实施例进行说明，如图1至3所示，为本申请实施例提供的一种内折式显示装置，即在折叠状态下柔性显示面板100位于支撑组件200的内侧，此时第一磁性件410位于第一滑件310朝向转轴220的一侧，第二磁性件420位于第二滑件320靠近转轴220的一侧。
在内折式显示装置由折叠状态转变为展平状态时，即当显示装置由图2所示的状态转变为图1所示的状态时，第一滑件310沿靠近转轴220的方向移动。当内折式显示装置处于展平状态时，第一滑件310和转轴220之间的距离最近，此时第一磁性件410和第二磁性件420之间的距离最近，且第一磁性件410和第二磁性件420之间的距离小于或等于第一距离阈值，使得第一磁性件410和第二磁性件420之间的磁性斥力能够驱动第一滑件310沿背离转轴220的方向移动，从而提高可弯折部120的平整 性。
在内折式显示装置由展平状态转变为折叠状态时，第一滑件310沿远离转轴220的方向移动，展平状态转变为折叠状态的初始，第一磁性件410和第二磁性件420的斥力能够驱动第一滑件310移动，从而让便于将展平状态弯折为折叠状态。当内折式显示装置处于折叠状态时，第一磁性件410和第二磁性件420之间的距离最远，此时第一磁性件410和第二磁性件420之间的距离大于第一距离阈值，第一磁性件410和第二磁性件420之间的作用力不会影响第一滑件310的运行，从而避免柔性显示面板100在折叠状态继续被拉伸，能够提高柔性显示面板100的使用寿命。
在上述实施例中，第一磁性件410可以设置于第一滑件310上、并位于第一滑件310上朝向转轴220的一侧，或者第一磁性件410设置于支撑部210、并位于第一滑件310朝向转轴220的一侧，或者第一滑件310和支撑部210上均设置有第一磁性件410，只要第一磁性件410位于第一滑件310朝向转轴220的一侧即可。第二磁性件420可以设置于第二滑件320上、并位于第二滑件320上靠近转轴220的一侧；或者第二磁性件420设置于转轴220，或者第二滑件320和转轴220上均设置有第二磁性件420，只要第二磁性件420位于第二滑件320靠近转轴220的一侧即可。
在另一可选的实施例中，滑动组件300为两组以上，两组以上的滑动组件300中至少有两组滑动组件300相对转轴220对称分布，此时第一磁性件410和第二磁性件420可以分设于该两组滑动组件300的第一滑件410上。在内折式显示装置由折叠状态转变为展平状态时，即当显示装置由图2所示的状态转变为图1所示的状态时，相对转轴220对称分布的两个第一滑件310沿靠近转轴220的方向移动，即相对转轴220对称分部的两个第一滑件310沿相互靠近的方向移动。当内折式显示装置处于展平状态时，两个第一滑件310之间的距离最近，此时第一磁性件410和第二磁性件420之间的距离最近，且第一磁性件410和第二磁性件420之间的距离小于或等于第一距离阈值，使得第一磁性件410和第二磁性件420之间的磁性斥力能够驱动第一滑件310沿背离转轴220的方向移动，从而提高可弯折部120的平整性。
如图4和图5所示，为外折式显示装置，即在折叠状态柔性显示面板100位于支撑组件200的外侧，此时第一磁性件410位于第一滑件310朝向转轴220的一侧，第二磁性件420位于第二滑件320上。
在外折式显示装置由折叠状态转变至展平状态时，第一滑件310沿远离转轴220的方向移动。当外折式显示装置处于展平状态时，第一滑件310和转轴220之间的距离最远，此时第一磁性件410和第二磁性件420之间的距离最远。此时，第一磁性件410设置于第一滑件310朝向转轴220的一侧，第二磁性件420设置于第二滑件320上，使得第一磁性件410和第二磁性件420之间的距离能够足够小并小于或等于第一距离阈值，使得第一磁性件410和第二磁性件420之间的磁性斥力能够驱动第一滑件310沿背离转轴220的方向继续移动，从而提高可弯折部120的平整性。
在上述实施例中，第一磁性件410可以设置于第一滑件310上、并位于第一滑件310上朝向转轴220的一侧，或者第一磁性件410设置于支撑部210、并位于第一滑件310朝向转轴220的一侧，或者第一滑件310和支撑部210上均设置有第一磁性件410，只要第一磁性件410位于第一滑件310朝向转轴220的一侧即可。
当显示装置在折叠状态和展平状态之间转变时，驱动第一滑件310和第二滑件320相互移动的方式有多种，例如第一滑件310和转轴220之间还连接有弹性结构，当显示装置在折叠状态和展平状态之间转变时，通过弹性结构的弹性变形使得第一滑件310和第二滑件320相对移动。或者，如图4和图5所示，第一滑件310上设置有滑槽311，第二滑件320上设置有滑杆323及扇形孔324，滑杆323上设置有沿滑槽311可移动的滑块，且滑杆323在扇形孔324内可转动设置。当显示装置在折叠状态和展平状态之间转变时，通过外力使得第一滑件310和第二滑件320之间能够相互滑动。
在一些可选的实施例中，支撑部210背离固定部110的一侧设置有第一支撑块211，且第一支撑块211对应于固定部110靠近可弯折部120的一侧，第二滑件320上设置有第一卡扣块321，在展平状态下，第一卡扣块321和第一支撑块211在显示装置的厚度方向上层叠设置。即在展平状 态下，第一卡扣块321和第一支撑块211在厚度方向(图1中的Z方向)上相互抵靠接触设置，使得第一卡扣块321能够向第一支撑块211提供朝向柔性显示面板100的支撑力。
在显示装置在折叠状态和展平状态之间转变时，固定部110和可弯折部120的连接部位易出现凹陷等问题。在本申请实施例的显示装置中，固定部110靠近可弯折部120的一侧设置有第一支撑块211，且在展平状态下，第二滑件320上的第一卡扣块321和第一支撑块211层叠设置，因此第一卡扣块321能够向第一支撑块211提供支撑，进而使得第一支撑块211能够通过支撑部210向固定部110提供支撑，避免固定部110出现凹陷等问题，进一步保证柔性显示面板100的平整性。
在一些可选的实施例中，支撑组件200还包括承载板230，承载板230设置于支撑部210和转轴220背离柔性显示面板100的一侧，即支撑部210、转轴220、滑动组件300和驱动组件400均设置于柔性显示面板100和承载板230之间。
承载板230上设置有第二支撑块231，第二支撑块231和第一支撑块211沿厚度方向间隔分布；第二滑件320上还设置有第二卡扣块322，在展平状态下，第二卡扣块322和第二支撑块231在厚度方向上层叠设置。
在这些可选的实施例中，通过设置第二支撑块231和第二卡扣块322，使得在厚度方向上第一支撑块211、第一卡扣块321、第二滑件320、第二卡扣块322和第二支撑块231依次层叠设置并相互支撑，能够提高第一支撑块211所在位置的支撑力，进而保证固定部110的平整性。
第一卡扣块321和/或第二卡扣块322与第二滑件320的连接方式有多种。例如，第一卡扣块321和/或第二卡扣块322可以利用螺栓、粘接、铆接或焊接等方式连接于第二滑件320。或者第一卡扣块321和/或第二卡扣块322与第二滑件320一体成型。
第一支撑块211与支撑部210的连接方式也可有多种。例如，第一支撑块211可以利用铆接、粘接或焊接等连接方式连接于支撑部210背离柔性显示面板100的表面，或者第一支撑块211和支撑部210一体成型。
在一些可选的实施例中，第一支撑块211朝向第一卡扣块321的表面 凹陷形成有第一卡槽212，在展平状态下，第一卡扣块321卡扣于第一卡槽212，进而保证第一支撑块211和第一卡扣块321之间相对位置的稳定性。
在这些可选的实施例中，第一支撑块211朝向第一卡扣块321的顶面与第二滑件320之间的距离小于第二卡扣块322凸出于第二滑件320的高度。使得第一卡扣块321移动至第一卡槽212内时，会先推动第一支撑块211移动，进而使得第一支撑块211带动支撑部210和固定部110移动，进一步保证柔性显示面板100的平整性。当第一卡扣块321位于第一卡槽212内时，能够向第一支撑块211提供限位力，防止第一支撑块211朝向转轴220移动，保证固定部110不回缩，进一步提高柔性显示面板100的平整性。
第一卡槽212的设置方式还有多种，例如第一卡槽212还可以设置于第一卡扣块321朝向第一支撑块211的表面，在展平状态下，第一支撑块211卡扣于第一卡槽212，进而保证第一支撑块211和第一卡扣块321之间相对位置的稳定性。只要使得第一支撑块211和第一卡扣块321中一者的表面设置有卡槽，在展平状态下，第一支撑块211和第一卡扣块321能够通过第一卡槽212相互卡扣配合，提高第一支撑块211和第一卡扣块321之间相对位置的稳定性即可。
在另一些可选的实施例中，第二支撑块231朝向第二卡扣块322的表面凹陷形成有第二卡槽232，在展平状态下，第二卡扣块322卡扣于第二卡槽232，进而保证第二支撑块231和第二卡扣块322之间相对位置的稳定性。
第二卡槽232的设置方式还有多种，例如第二卡槽232还可以设置于第二卡扣块322朝向第二支撑块231的表面，在展平状态下，第二支撑块231卡扣于第二卡槽232，进而保证第二支撑块231和第二卡扣块322之间相对位置的稳定性。只要使得第二支撑块231和第二卡扣块322中一者的表面设置有卡槽，在展平状态下，第二支撑块231和第二卡扣块322能够通过第二卡槽232相互卡扣配合，提高第二支撑块231和第二卡扣块322之间相对位置的稳定性即可。
在上述任一实施例中，对于滑动组件300的个数没有特别限制。例如，可以设置一组滑动组件300。或者如图3所示，可以设置两组以上的滑动组件300，两组以上的滑动组件300沿转轴220的轴向(即图3中的Y方向)间隔分布。使得通过两组以上的滑动组件300中第一滑件310和第二滑件320的相互滑动，能够带动不同位置的支撑部210移动，进而保证柔性显示面板100各处的平整性。
在另一些可选的实施例中，两组以上的滑动组件300分设于转轴220的两侧，使得转轴220两侧的两个支撑部210均能够在滑动组件300的带动下沿远离转轴220的方向移动，进而使得两个固定部110沿远离彼此的方向上拉伸，提高可弯折部120的平整性。
显示装置例如采用双轴式或者单轴式，双轴式即支撑组件200包括两个转轴220，两个转轴220沿垂直于其轴向的方向并排设置。此时分设于转轴220两侧的第二滑件320分别连接与其相邻的转轴220。单轴式即支撑组件200包括一个转轴220，此时，分设于转轴220两侧的第二滑件320沿转轴220的轴向交错分布，两个以上的第二滑件320分别连接于转轴220的不同位置。
两组以上的滑动组件300可以选用一组驱动组件400驱动，例如第一磁性件410和第二磁性件420均呈条状并沿转轴220的轴向延伸成型，使得第一磁性件410和第二磁性件420能够向多组滑动组件300的第二滑件320提供驱动力。或者，在另一些可选的实施例中，驱动组件400的个数为两组以上，各驱动组件400与滑动组件300一一对应设置，使得各驱动组件400分别驱动滑动组件300中的第二滑件320移动。
本申请实施例另一方面还提供一种移动终端，包括上述的显示装置。移动终端例如为折叠手机、折叠平板或折叠学习机等。由于本申请实施例的移动终端包括上述的显示装置，因此本申请实施例的移动终端具有上述显示装置所具有的有益效果，在此不再赘述。
