实施例一
本申请实施例一提供一种显示装置，所述显示装置包括：显示面板；至少一个功能膜，设置于所述显示面板的至少一侧，每个所述功能膜包括第一磁性部件；其中，所述显示装置还包括位于所述显示面板和各所述功能膜之间的第二磁性部件，所述第二磁性部件与所述显示面板固定连接，并与设置于所述显示面板同侧的所述第一磁性部件之间具有磁性吸附力，所述显示面板通过所述第二磁性部件与所述功能膜滑动连接。
本申请提供的显示装置通过相互吸引的第一磁性部件和第二磁性部件，使包含有所述第一磁性部件的功能膜和与所述第二磁性部件固定连接的显示面板滑动连接，从而避免了通过光学胶连接所述显示面板和功能膜而导致的膜层剥离问题，并且滑动连接的方式使得所述显示面板和功能膜在弯折过程中具有一定的自由度，有效提高了显示面板的稳定性和良率，降低了生产制造成本。
本实施例中，所述第一磁性部件和所述第二磁性部件之间具有磁性吸附力，两者相互吸引，以使得所述显示面板和所述功能膜能够较为紧密的结合到一起，避免了使用光学胶粘接固定所述显示面板和功能膜。但本申请对所述第一磁性部件和所述第二磁性部件之间的磁性吸附方式不作限制，两者例如可以通过单体磁铁、磁吸导轨、橡胶磁条、磁悬液、磁粉、磁性油墨和金属结构中的任意多种组合搭配实现。
具体的，所述显示装置为柔性显示装置，其类型可以是柔性OLED显示装置、柔性微发光二极管（英文全称：Micro Light Emitting Diode，简称Micro LED）显示装置或柔性迷你发光二极管（英文全称：Mini Light Emitting Diode，简称Mini LED）显示装置。优选的，所述显示装置为柔性OLED显示装置，所述柔性OLED显示装置中的显示面板类型为柔性OLED显示面板。
图1示出了本申请实施例一提供的显示装置的立体结构示意图，如图1所示，本实施例中，所述显示装置100包括弯折轴AA`，所述显示装置100能够沿所述弯折轴AA`自由弯折。需要说明的是，所述显示装置100可以为折叠显示装置或卷曲显示装置，所述显示装置100的弯折轴可以为一条或多条，当所述显示装置100的弯折轴为多条时，所述显示装置100的弯折轴包括弯折轴AA`及与弯折轴AA`平行的其他弯折轴。
图2示出了本申请实施例一提供的显示装置沿AA`线剖开的剖面示意图，结合图1和图2所示，本实施例中，所述显示装置100还包括与所述弯折轴AA`垂直的两个相对的侧边102，两个所述侧边102上分别设置有包边部件101。所述包边部件101用于对所述功能膜及所述显示面板进行限位，并覆盖两个所述侧边102及与两个所述侧边102邻接的所述显示装置100的两个边缘，其中，所述包边部件101均位于所述显示装置100的非显示区，以避免降低所述显示装置100的屏占比。所述包边部件101限定了所述功能膜相对于所述显示面板的滑动方向，使得所述功能膜相对于所述显示面板滑动的方向与所述侧边102的延伸方向相同，有效避免了显示面板和功能膜滑动连接导致的所述显示装置100在沿弯折轴AA`延伸的方向上发生膜层错位的问题。
其中，所述包边部件101具有柔性。在本实施例中，所述包边部件101的材质为橡胶，所述包边部件101采用橡胶材质能够便于所述显示装置100弯折，同时对所述显示装置100起到良好的缓冲抗震作用。
本实施例中，所述显示装置100中的功能膜可以为一个，可以为多个。当所述功能膜为多个时，所述多个功能膜可以分别设置在所述显示装置100的两侧。下面以所述显示装置100包括多个功能膜为例进行说明。
图3示出了本申请实施例一提供的显示装置的膜层结构示意图；图4示出了本申请实施例一提供的第一功能膜的俯视图；图5示出了本申请实施例一提供的第二磁性部件的俯视图；图6示出了本申请实施例一提供的偏光片的结构示意图。结合图1-图6所示，本申请实施例一提供的显示装置100包括：显示面板10，所述显示面板10例如包括：驱动电路层以及位于所述驱动电路层上的发光功能层。所述显示装置100还包括设置于所述显示面板10两侧的第一功能膜130和第二功能膜160，其中，所述第一功能膜130包括一第一磁性部件132，且所述第一功能膜130和所述显示面板10之间设置有一第二磁性部件122，所述第一磁性部件132和所述第二磁性部件122之间具有磁性吸附力；所述第二功能膜160包括一第一磁性部件161，且所述第二功能膜160和所述显示面板10之间设置有一第二磁性部件150，所述第一磁性部件161和所述第二磁性部件150之间具有磁性吸附力。
本实施例中，所述显示面板10包括第一侧和第二侧，其中，所述显示面板10的第一侧依次层叠设置有封装层110、第二磁性部件122、偏光片120和第一功能膜130；所述显示面板10的第二侧依次层叠设置有背板140、第二磁性部件150、第二功能膜160和缓冲层170。
本实施例中，所述第一功能膜130为设置在所述显示面板10第一侧的覆盖窗，所述覆盖窗例如设置于所述显示装置100的最外侧，以保护所述显示面板10免受外界的侵害。所述覆盖窗包括所述第一磁性部件132，具体的，所述覆盖窗包括覆盖窗本体131和位于所述覆盖窗本体131两侧的所述第一磁性部件132，所述第一磁性部件132与所述覆盖窗本体131同层邻接设置并固定连接，且所述第一磁性部件132在所述显示面板10上的垂直投影位于所述显示面板10的非显示区。
本实施例中，由于所述第一磁性部件132与所述覆盖窗本体131同层邻接设置，使得所述覆盖窗的整体厚度并不会增加，可以实现显示装置100的薄化；并且所述第一磁性部件132在所述显示面板10上的垂直投影位于显示面板10的非显示区，从而使得所述第一磁性部件132并不会降低所述显示面板10的显示面积，保证了所述显示装置100的显示区占比。
本实施例中，所述第一磁性部件132与所述包边部件101同侧设置，所述第一磁性部件132的延伸方向与垂直于所述弯折轴AA`的所述侧边的延伸方向相同。
本实施例中，所述覆盖窗本体131为柔性有机材料、超薄玻璃或其他可弯折材料。所述第一磁性部件132由金属材料制成，并具有金属网格结构。通过将所述第一磁性部件132设置为具有镂空部的金属网格结构，能够有效降低所述第一磁性部件132与所述覆盖窗本体131的结合难度，降低生产制造成本。具体的，所述第一磁性部件132通过金属网格镶嵌的方式固定于所述覆盖窗本体131的两侧。并且，所述第一磁性部件132具有的金属网格结构还能够在显示装置100弯折过程中通过网格结构形变抵消弯折应力，提升所述显示装置100的弯折性能。优选的，基于工艺与性能因素的考量，所述金属网格的目数为x，其中，500≤x≤1000，目数即每平方厘米面积内的目孔数，目数越高，所述第一磁性部件132单位面积内的孔眼越多，通过将所述第一磁性部件132中的所述金属网格的目数控制在500至1000范围内，可以使所述第一磁性部件132在具备优良的弯折性能的同时，使所述第一磁性部件132中的开孔面积占比与金属面积占比达到一定的均衡，保证所述第一磁性部件132与第二磁性部件122之间的磁性吸附强度，同时避免因单位面积内的孔眼设置过多导致的物料成本增加，并有效的控制成本。
本实施例中，所述第二磁性部件122为设置于所述显示面板10和所述覆盖窗之间的第一磁性油墨层，所述第一磁性油墨层在所述显示面板10上的垂直投影位于所述显示面板10的非显示区，且所述第一磁性油墨层在所述覆盖窗上的垂直投影覆盖所述第一磁性部件132。由于所述第一磁性油墨层在所述显示面板10上的垂直投影位于所述显示面板10的非显示区，从而使得所述第一磁性油墨层的设置并不会降低所述显示装置100的屏占比；并且，由于所述第一磁性油墨层在所述覆盖窗上的垂直投影覆盖所述第一磁性部件132，从而使得位于所述覆盖窗本体131两侧的第一磁性部件132能够与所述第一磁性油墨层产生磁性吸附力，在保证所述覆盖窗与所述显示面板10稳定结合的同时，使所述显示面板10在弯折过程中能够相对于所述覆盖窗沿所述侧边的延伸方向滑动，提高所述显示装置100的弯折性能。具体的，所述第一磁性油墨层在所述显示面板10上的垂直投影位于所述显示面板10的四个边缘上，并与所述显示面板10的非显示区对应设置。
本实施例中，所述第一磁性油墨层包括遮光油墨和掺杂于所述遮光油墨中的磁粉，所述磁粉的直径为y，其中，0.5μm≤y≤50μm。由于所述遮光油墨的初始状态为液态，用于与所述第一磁性部件132产生磁性吸附力的所述磁粉通过掺杂方式形成在所述遮光油墨中，使得所述磁粉能够均匀的分布在所述遮光油墨中，保证所述第二磁性部件122与所述第一磁性部件132之间的吸附力度的均一性。并且，磁粉的直径大小还会直接影响单个所述磁粉与所述第一磁性部件132之间的磁性吸附强度及所述第一磁性油墨层的厚度，通过将所述磁粉的直径控制在0.5μm至50μm的范围内，能够在保证所述第一磁性部件132与所述第二磁性部件122之间的吸附强度的同时，将所述第一磁性油墨层的厚度控制在一合理范围内，避免由于所述第一磁性油墨层的设置导致的显示装置100的整体厚度过厚的问题，有利于所述显示装置100的薄化。优选的，所述第一磁性油墨层的厚度等于所述磁粉的直径大小。进一步的，所述第一磁性油墨层中的所述遮光油墨的颜色例如为黑色，在显示面板10中，显示面板10的非显示区往往设置有金属走线，由于所述遮光油墨的颜色为黑色，使得所述第一磁性油墨层在实现与所述第一磁性部件132相互吸附的同时，还能够起到遮蔽显示面板10中位于非显示区的金属走线的作用。
本实施例中，所述第一磁性油墨层例如通过打印的方式所形成，但本实施例对所述第一磁性油墨层的形成方式并不做限制，在本申请的其他实施例中，所述第一磁性油墨层还可以通过涂布的方式形成。
本实施例中，所述第一磁性油墨层为单独设置的膜层，所述第一磁性油墨层位于所述显示面板10和所述偏光片120之间。
本实施例中，所述显示装置100例如还包括封装层110，所述封装层110设置在所述显示面板10和所述偏光片120之间，用于防止外界水汽或氧气对所述显示面板10的侵蚀。所述封装层110可以由有机封装层和无机封装层多层堆叠所形成。所述第一磁性油墨层具体位于所述封装层110和所述偏光片120之间。
需要说明的是，本申请对独立设置的所述第二磁性部件122的位置并不作限定，在本申请的其他实施例中，所述第二磁性部件122例如还可以设置在所述偏光片120和所述第一功能膜130之间，以缩短所述第二磁性部件122与所述第一磁性部件132之间的距离，进一步提升所述第二磁性部件122与所述第一磁性部件132之间的磁性吸附力。
本实施例中，所述第二功能膜160为设置在所述显示面板10第二侧的金属支撑层（英文全称：Metal sheet，简称MS），所述显示面板10的第二侧也即所述显示面板10远离所述第一功能膜130的一侧。具体的，所述显示装置100还包括位于所述显示面板10远离所述第一功能膜130一侧的背板（英文全称：Back plate，简称BP）140，所述背板140用于承载所述显示面板10，所述金属支撑层设置在所述背板140远离所述显示面板10的一侧。
本实施例中，所述金属支撑层包括第一磁性部件161，所述第一磁性部件161由所述金属支撑层图案化所形成。
具体的，所述第一磁性部件161由形成所述金属支撑层的金属材料制成，并具有金属网格结构。所述网格结构的第一磁性部件161在所述显示面板10上的垂直投影可以位于所述显示面板10的显示区和/或非显示区。这是由于所述显示面板10的第二侧为背光侧，不存在显示需求，因此，所述第一磁性部件161在所述显示面板10上的垂直投影不仅可以位于显示面板10的显示区还可以位于非显示区。
需要说明的是，金属支撑层为显示装置100中的固有膜层，以对所述显示面板10起支撑补强作用和/或散热作用，故一般采用具有较强支撑强度和/或较高散热效果的金属制成，如不锈钢SUS等。而不锈钢中的很多系列是可以直接被磁性物质所吸附的。因此，本申请利用所述金属支撑层的自身特性，将其直接图案化形成所述第一磁性部件161，可以避免显示装置100整体厚度的增加，并有效降低所述显示装置100的制造成本。并且，图案化的所述第一磁性部件161还能够有效降低显示装置100的弯折应力，提升所述显示装置100的弯折性能。
本实施例中，所述背板140和所述第二功能膜160之间设置有所述第二磁性部件150，所述第二磁性部件150为第二磁性油墨层，所述第二磁性油墨层在所述第二功能膜160上的垂直投影覆盖所述第一磁性部件161，以保证所述第二磁性油墨层与所述第一磁性部件161之间具有较强的磁性吸附力，避免光学胶的使用，并使所述显示面板10能够相对于所述第二功能膜160滑动。具体的，所述第二磁性油墨层可以通过涂布的方式直接涂布于所述背板140远离所述显示面板10的一侧，所述第二磁性油墨层例如包括黑色油墨和掺杂于所述黑色油墨中的磁粉。优选的，所述第二磁性油墨层的材料与所述第一磁性油墨层的材料相同，以降低物料种类和生产制造成本。
本实施例中，所述缓冲层170设置在所述金属支撑层远离所述背板140的一侧，所述缓冲层170例如由泡棉材料制成。
实施例二
图7示出了本申请实施例二提供的显示装置的膜层结构示意图；图8示出了本申请实施例二提供的偏光片的结构示意图。结合图1、图2、图7和图8所示，本申请实施例二提供一种显示装置100，所述显示装置100包括显示面板10，所述显示面板10包括第一侧和第二侧，其中，所述显示面板10的第一侧依次层叠设置有封装层110、偏光片120和第一功能膜130；所述显示面板10的第二侧依次层叠设置有背板140、第二磁性部件150、第二功能膜160和缓冲层170，且所述显示装置100中的第一功能膜130为所述覆盖窗，所述覆盖窗包括第一磁性部件132，所述覆盖窗和所述显示面板10之间设置有能够与所述第一磁性部件132产生磁性吸附力的第二磁性部件122，所述第二磁性部件122为第一磁性油墨层。即本申请实施例二提供的显示装置100的结构与实施例一相类似，本实施例对于相同部分在此不再一一赘述。
不同的是，本申请实施例二提供的显示装置100中，作为第二磁性部件122的第一磁性油墨层不再设置于所述封装层110和所述偏光片120之间。
具体的，所述显示装置100包括设置于所述显示面板10和所述第一功能膜130之间的偏光片120，所述偏光片120包括偏光片本体121和设置于所述偏光片本体121四周的所述第二磁性部件122，所述偏光片本体121与所述显示面板10的显示区相对应，所述第二磁性部件122与所述显示面板10的非显示区相对应。在常规的OLED显示装置中，偏光片通常设置于覆盖窗和显示面板之间，以起到降低环境反射光、提升显示面板显示效果的作用，本申请实施例保留了具有降低环境反射光功能的偏光片本体121，同时在对应所述显示面板10非显示区的偏光片120中形成所述第二磁性部件122，从而能够在实现与第一磁性部件132相互吸引，提升显示装置100弯折性能的同时，不增加所述显示装置100的整体厚度，保证所述显示装置100的薄化和视觉美观。并且，位于所述偏光片120中的所述第二磁性部件122还和所述第一磁性部件132直接接触，从而缩短了所述第二磁性部件122和所述第一磁性部件132之间的距离，进一步提高了所述第一功能膜130和显示面板10的装配稳定性。
本实施例中，可以采取对偏光片120裁切的方式，使偏光片本体121在对应所述显示面板10的非显示区的位置缺失，并在所述缺失的位置上形成所述第一第二磁性部件122。但本申请对所述第二磁性部件122在所述偏光片120中的位置不作限制，在本申请的其他实施例中，所述偏光片120包括多个膜层，可以将所述多个膜层中的至少部分膜层在对应所述显示面板10的非显示区的位置替换为所述第二磁性部件122。
综上所述，本申请提供一种显示装置，所述显示装置包括：显示面板；至少一个功能膜，设置于所述显示面板的至少一侧，每个所述功能膜包括第一磁性部件；其中，所述显示装置还包括位于所述显示面板和各所述功能膜之间的第二磁性部件，所述第二磁性部件与所述显示面板固定连接，并与设置于所述显示面板同侧的所述第一磁性部件之间具有磁性吸附力，所述显示面板通过所述第二磁性部件与所述功能膜滑动连接。本申请提供的显示装置通过相互吸引的第一磁性部件和第二磁性部件，使包含有所述第一磁性部件的功能膜和与所述第二磁性部件固定连接的显示面板滑动连接，从而避免了通过光学胶连接显示面板和功能膜而导致的膜层剥离问题，并且滑动连接的方式使得显示面板和功能膜在弯折过程中具有一定的自由度，有效提高了显示面板的稳定性和良率，降低了生产制造成本。
以上对本申请实施例所提供的显示面板及其显示装置进行了详细介绍，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，以上实施例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，综上所述，本说明书内容不应理解为对本申请的限制。
