Description

一种显示模组 技术领域
本发明属于液晶显示技术领域，具体地讲，涉及一种柔性显示面板的组装方式。
背景技术
随着OLED显示技术的发展日趋成熟，广大消费者体验到了OLED显示与传统LCD显示的巨大差异，随之而来的是OLED消费市场的迅速增长。由于OLED自发光的特性，使得响应时间短、高对比度、广视角、广色域、显示面板轻薄化、可弯折性等特点得以实现。特别是OLED显示面板的可弯折性，给消费者带来了颠覆性的概念，因此Flexible(可弯折)OLED近年来是行业发展的主流。
然后，可弯折的显示面板对电子设备自身器件的组装也形成了挑战。传统终端厂商，往往采用黏贴的方式将显示面板固定在中框上。对于玻璃基板显示面板，由于玻璃基板本身的刚性比较适合采用这种方式进行固定。但是，对于OLED柔性显示面板而言，采用中框和胶材的固定黏贴这种组装方式使得显示面板在弯折过程中，会对柔性显示面板产生应力，极易造成柔性显示面板的损坏，使得产品的弯折可靠性大大减低。
同时，当固定本身就很柔软的显示面板时，由于基板本身柔软，因此在采用该方式的时候往往会出现粘贴位置不准，往往会带来重工、固定困难，从而导致良率降低的问题，影响了生产效率，提高了生产成本。
人们希望找到一种新的应用于柔性显示面板的固定方式。
发明内容
为了解决上述现有技术存在的问题，本发明提供一种新的显示模组，包括：
中框，以及设置在所述中框上的柔性显示面板，所述中框设有第一磁性件；
所述柔性显示面板包括有基板，所述基板上设有与所述第一磁性件对应的第二磁性件，使得所述柔性显示面板、所述中框之间通过所述第一磁性件、第二磁性件配合连接。
其中，所述中框包括：第一矩形部和第二矩形部，以及，连接于所述第一矩形部和第二矩形部之间的转动组件；所述第一矩形部、第二矩形部绕所述转动组件相对转动，使得所述中框至少具有折合状态和平展状。
其中，所述第一矩形部、第二矩形部对应于所述显示面板均具有用于支承所述显示面板的支撑凹槽，所述第一磁性件设置于所述支撑凹槽上。
其中，所述转动组件包括至少两个铰接件及设置于两铰接件之间的转动轴：所述铰接件设置于所述第一矩形部与所述第二矩形部邻接的侧面之间。
其中，所述第一磁性件与所述中框一体成型。
其中，所述柔性显示面板包括从下至上依次设置于所述基板上的阴极层、电子传送层、有机发射器、空穴注射层、阳极层和保护层。
其中，所述第二磁性件与所述基板一体成型。
有益效果：
本发明通过采用磁性固定的方式，不需要黏胶就可以把柔性显示面板固定到中框，满足终端厂家的需求。同时由于采用磁性材料，适合柔性显面板的弯折操作，减少了中框及胶材给柔性显示面板带来的应力，并且可以反复重工，不损伤显示面板的性能，减少了工作量，提高了工作效率，降低了生产成本。
附图说明
通过结合附图进行的以下描述，本发明的实施例的上述和其它方面、特点和优点将变得更加清楚，附图中：
图1是本发明显示面板与中框贴合过程的结构示意图。
图2是本发明中框的结构示意图。
图3是本发明中框的结构分解图。
具体实施方式
以下，将参照附图来详细描述本发明的实施例。然而，可以以许多不同的形式来实施本发明，并且本发明不应该被解释为限制于这里阐述的具体实施例。相反，提供这些实施例是为了解释本发明的原理及其实际应用，从而使本领域的其他技术人员能够理解本发明的各种实施例和适合于特定预期应用的各种修改。
本发明提供的显示模组，如图1所示，其包括中框10，以及安设在所述中框10内的柔性显示面板20。本发明的柔性显示面板是采用OLED柔性显示面板为例。
其中，所述柔性显示面板20包括从下至上依次设置于所述基板21上的阴极层22、电子传送层23、有机发射器24、空穴注射层25、阳极层26和保护层27。一般地，基板21、保护层27的材质为塑料。
结合图2所示，所述中框10上、对应于显示面板20的一面设有第一磁吸件11。所述基板21上设有与所述第一磁性件11对应的第二磁性件，使得所述柔性显示面板20、所述中框10之间通过所述第一磁性件11、第二磁性件配合连接。本实施例中，第二磁性件优选与所述基板21一体成型，即在基板21的制备过程中直接引入磁性材料，使得整个基板本身就带有磁性。换句话说，基板可认为是第二磁吸件。在其他实施例中，第二磁吸件也可以采用黏贴的方式与基板结合。
为了配合柔性显示面板的可弯折性能，中框也制作为可弯折的结构。如图2、图3所示，本发明的中框10包括第一矩形部12、第二矩形部13以及连接于所述第一矩形部12、第二矩形部13之间的转动组件30，所述第一矩形部12、第二矩形部13绕所述转动组件30相对转动，使得所述中框10至少具有折合状态和平展状态。
进一步地，所述第一矩形部12、第二矩形部13对应于所述柔性显示面板 20均具有用于支承所述柔性显示面板20的支撑凹槽14，所述第一磁性件11设置于所述支撑凹槽14上。具体地，第一磁吸件11可以通过黏贴的方式组合于支撑凹槽14上，也可以在中框的制作材料中直接引入磁性材料，与中框一体成型，使得整个中框均带有磁性。
结合图3可知，所述转动组件30包括至少两个铰接件31及设置于两铰接件31之间的转动轴32：当所述中框10处于平展状态，第一矩形部12与所述第二矩形部13具有相邻接的侧面121、侧面131，所述铰接件31于所述第一矩形部12与所述第二矩形部13邻接的侧面121、侧面131之间。所述第一矩形部12与所述第二矩形部13绕所述转动轴32转动，所述第一矩形部12与所述第二矩形部13之间能够成任意角度的平面夹角，使得中框至少具有折合状态和平展状态之余，也能够似“双翼”般任意角度展开，满足柔性显示面板的要求。
组装时，中框10先展开平铺，然后将柔性显示面板20放置在中框10内预设安装的位置，柔性显示面板20上设有第二磁吸件的基板21，与设有第一磁吸件11的中框10对应，两者相互吸引固定，安装完成。由于显示面板与中框仅仅通过磁吸作用固定，即使安装时贴合不准确，可以无限次拆卸分离、再重新贴合安装，不影响柔性显示面板的性能；而且，磁吸的固定方式不同于黏胶，可以在柔性显示面板弯折时，允许柔性显示面板和中框的接触面产生相对移位，减少应力对显示面板的损害，在柔性显示面板恢复平整时，显示面板又会在磁吸作用下与中框重新贴合，保持良好的固定结构。
本发明通过采用磁性固定的方式，不需要黏胶就可以把柔性显示面板固定到中框，满足终端厂家的需求。同时由于采用磁性材料，适合柔性显示面板的弯折操作，减少了中框及胶材带来的应力，并且减少了工作量，提高了工作效率，降低了生产成本。
虽然已经参照特定实施例示出并描述了本发明，但是本领域的技术人员将理解：在不脱离由权利要求及其等同物限定的本发明的精神和范围的情况下，可在此进行形式和细节上的各种变化。
