如图1～3所示，本公开一些实施例提供一种显示设备100，包括显示模组1、背板组件2、支架组件3和系统电路组件4。显示模组1包括显示面板11，显示面板11具有出光面111和与出光面111相对的背面112。背板组件2设置于显示面板11的背面112背离出光面111的一侧，背板组件2与显示模组1固定。背板组件2的远离显示模组1的表面与支架组件3固定，支架组件3具有镂空区3A。系统电路组件4固定于支架组件3的镂空区3A内，且系统电路组件4与显示模组1电连接；系统电路组件4被配置为向显示模组1 提供信号，以使显示模组1进行显示。
该显示设备100可以用作手机、平板电脑、个人数字助理(personal digital assistant，PDA)、数码相框、导航仪、车载电脑等具有任何显示功能的产品或者部件，本公开的实施例对显示装置的用途不做特殊限制。
在一些实施例中，显示面板11为柔性显示面板。在一些示例中，显示面板11为柔性自发光显示面板。例如，显示面板11为有机电致发光二极管(Organic Light-Emitting Diode，OLED)显示面板。当然，显示面板11还可以是其他类型的显示面板，本公开实施例中并限于显示面板11为柔性显示面板。
需要说明的是，本公开实施例中的显示设备100可以是平面显示设备，也可以是曲面型显示设备。在显示设备100为平面显示设备的情况下，显示面板11为柔性显示面板。
在一些实施例中，如图3、图4A～4B所示，支架组件3包括支撑部31、两个包边支架32和至少两个可拆卸固定结构33。
如图3所示，支撑部31沿第一方向X延伸，镂空区3A设置在支撑部31中。两个包边支架32沿第一方向X分别设置于支撑部31的两侧。每个包边支架32沿第二方向Y延伸，且包边支架32中远离支撑部31的端部为翻边部321。第一方向X为出光面111的一边的延伸方向，第二方向为出光面111的另一边的延伸方向，所述一边与所述另一边为出光面111的相邻两边。例如，第一方向X为出光面111的长边的延伸方向，第二方向Y为出光面111的短边的延伸方向。
如图4A和4B所示，每个包边支架32通过至少一个可拆卸固定结构33与对应的支撑部31的端部固定，即，两个包边支架32中的一个通过至少一个可拆卸固定结构33与支撑部31的一端部固定，两个包边支架32中的另一个通过至少一个可拆卸固定结构33与支撑部31的另一端部固定。相应地，两个包边支架32之间通过支撑部31连接。在一些实施例中，包边支架32通过多个可拆卸固定结构33与对应的支撑部31的端部固定。
如图4A和图4B所示，每个包边支架32与支撑部31的端部中，其中一者具有至少一个通孔K，每个可拆卸固定结构33穿过一个通孔K与另一者固定。在一些示例中，如图4A和图5所示，包边支架32具有至少一个通孔K，每个可拆卸固定结构33穿过一个通孔K与支撑部31的端部固定。在另一些示例中，如图4B所示，支撑部31的端部具有至少一个通孔K，每个可拆卸固定结构33穿过一个通孔K与包边支架32固定。在包边支架32通过多个可 拆卸固定结构33与对应的支撑部31的端部固定的情况下，在一些示例中，包边支架32与支撑部31的端部中，其中一者具有一个通孔K，每个可拆卸固定结构33穿过该通孔K与另一者固定。在另一些示例中，包边支架32与支撑部31的端部中，其中一者具有多个通孔K，多个通孔K与多个可拆卸固定结构33一一对应，每个可拆卸固定结构33穿过对应的一个通孔K与另一者固定。
可拆卸固定结构33的外壁与通孔K的孔壁之间具有间隙，以在支撑部31与包边支架32组装时，能够使包边支架32与支撑部31相对移动，从而调整包边支架32和支撑部31之间的相对位置。在一些实施例中，在支撑部31与包边支架32组装时，使包边支架32相对支撑部31沿第一方向X移动，在包边支架32和支撑部31之间的相对位置调整结束后，通过可拆卸固定结构33将包边支架32和支撑部31完全锁紧，使得包边支架32和支撑部31之间不再发生相对移动。
需要说明的是，包边支架32与支撑部31可以发生相对移动的最大距离可根据实际需求来设定，基于此，根据设定的最大距离，通过合理设置通孔K的尺寸以及可拆卸固定结构33的尺寸来实现。
在上述的支架组件3用于与背板组件2和显示模组1进行组装时，背板组件2和显示模组1设置在支撑部31的沿支架组件3的厚度方向的一侧。两个包边支架32的翻边部321沿第一方向X位于显示模组1的两侧，相应地，两个包边支架32的翻边部321沿第一方向X位于背板组件2的两侧。每个翻边部321和显示模组1的沿第一方向X相对的两侧侧面中的一个侧面相对，以对该侧面进行保护。在一些示例中，翻边部321与显示模组1的侧面之间的间距小于或等于预设宽度。预设宽度可以根据实际情况设定，示例的，该预设宽度小于或等于1mm。由于包边支架32与支撑部31的相对位置可调，使得两个包边支架32的翻边部321之间的距离可调。由此，翻边部321和显示模组1的侧面之间的间距可调，从而可将该间距调整至所需的范围内。支架组件3中可拆卸固定结构33的设置，在支架组件3和背板组件2、显示模组1进行组装时，可通过对可拆卸固定结构33的操作，随时调整包边支架32与支撑部31沿第一方向X相对位置。
对于曲面显示设备而言，显示面板11和背板组件2都是弯曲的。如图6A～6B所示，在一些示例中，由于显示面板11和背板组件2的材料和特性不同，导致原为平面结构的且组装在一起的显示面板11和背板组件2在弯曲过程中的形变能力不同，使得弯曲后的显示面板11一侧面和背板组件2的相应 侧面(该侧面和该相应侧面位于显示面板11和背板组件2的同一侧)会存在一定的错位。并且，随着显示面板11和背板组件2的弯曲程度增加，这种错位会越来越严重。
例如，如图6B所示，显示面板11和背板组件2向下弯曲，且显示面板11远离背板组件2的表面的弯曲边的延伸方向与第一方向X平行，显示面板11远离背板组件2的表面的未弯曲的边的延伸方向与第二方向Y平行。由于显示面板11和背板组件2在弯曲过程中的形变能力不同，导致显示面板11的一侧面和背板组件2的相应侧面在第一方向X上会存在偏差dx，使得显示面板11的该侧面和背板组件2的相应侧面无法对齐。
虽然在制作显示面板11和背板组件2时可以控制该偏差，在一定程度上减少错位程度，但由于曲面显示设备在实际弯曲时的曲率半径和设计时的曲率半径无法完全匹配，显示面板11和背板组件2在弯曲后的错位现象仍然不可避免。同时，偏差程度本身的一致性也较差，在不同的曲面显示设备上会呈现不同的偏差。
在本公开实施例中，如图4A所示，显示设备的组装过程，由于包边支架32与支撑部31的相对位置可调，因而，可根据曲面显示设备的实际情况对包边支架32与支撑部31的相对位置进行调节，从而对翻边部321和显示模组1的侧面之间的间距G1进行调整。由此，可将该间距G1调整到规定范围内，使不同的显示设备100的边缘缝隙大致相等，满足工业生产的一致性要求。
在一些实施例中，如图4A和图4B所示，包边支架32除包括翻边部321外，还包括连接部322，连接部322和翻边部321形成L型构造。连接部322与支撑部31的端部沿支架组件3的厚度方向层叠设置，所述至少一个通孔K设置在连接部322与支撑部31的端部中的一者中。在一些示例中，如图4A所示，所述至少一个通孔K设置在连接部322中，每个可拆卸固定结构33穿过一个通孔K与支撑部31的端部固定。在另一些示例中，如图4B所示，所述至少一个通孔K设置在支撑部31的端部，每个可拆卸固定结构33穿过一个通孔K与连接部322固定。
如图5所示，在一些示例中，连接部322和翻边部321连接形成的角为弧形倒角324。这样，连接部322和翻边部321在连接位置处平滑过渡，避免应力集中，从而提高结构性能，此外还可以避免存在毛刺，防止对背板组件2造成损伤。
在一些示例中，如图4A和5所示，连接部322包括第一连接子部3221和第二连接子部3222，第一连接子部3221位于第二连接子部3222与翻边部 321之间，且第一连接子部3221分别与第二连接子部3222、翻边部321连接。第二连接子部3222与支撑部31的端部沿支架组件3的厚度方向层叠设置，第一连接子部3221与支撑部31在支架组件3的厚度方向上无交叠。在所述至少一个通孔K设置在连接部322的实施例中，所述至少一个通孔K设置在第二连接子部3222中。
在一些实施例中，如图4A所示，支撑部31的端部朝向第二连接子部3222的一侧设置有至少一个螺纹孔(以下为方便描述，将该螺纹孔称为第一螺纹孔311B)，可拆卸固定结构33包括具有螺纹的紧固件，具有螺纹的紧固件穿过设置于第二连接子部3222中的一个通孔K与对应的一个第一螺纹孔311B固定连接。这里，第一螺纹孔311B可以贯穿支撑部31的端部，也可以不贯穿支撑部31的端部。
在一些示例中，如图4A所示，该通孔K为沉孔，具有螺纹的紧固件置于沉孔中，具有螺纹的紧固件不会凸出于第二连接子部3222远离支撑部31的一侧之外，使支架组件3在该处的外表面平整。
在另一些示例中，该通孔K为腰型孔，该通孔K沿第一方向X的长度大于该通孔K沿第二方向Y的宽度。
示例的，具有螺纹的紧固件为螺栓。螺栓包括螺杆和螺母，螺栓的螺杆穿过通孔K后，伸入第一螺纹孔311B内。通过旋转螺杆，使螺杆进入支撑部31的深度逐渐增加，当螺帽朝向螺杆的表面与第二连接子部3222被压紧，且第二连接子部3222的朝向支撑部31的表面与支撑部31也被压紧时，包边支架32与支撑部31固定连接在一起。
又示例的，具有螺纹的紧固件为双头螺柱，可拆卸固定结构33还包括螺母，螺母套设于双头螺柱的一端。双头螺柱的另一端穿过通孔K后，伸入第一螺纹孔311B内。通过旋转螺杆，使双头螺柱进入支撑部31的深度逐渐增加，当螺母朝向支撑部31的表面与第二连接子部3222被压紧，且第二连接子部3222的朝向支撑部31的表面与支撑部31也被压紧时，包边支架32与支撑部31固定连接在一起。
在另一些实施例中，如图4B所示，支撑部31的端部具有至少一个通孔K，包边支架32的连接部322朝向支撑部31的端部的一侧设置有至少一个第二螺纹孔3223。可拆卸固定结构33包括具有螺纹的紧固件，具有螺纹的紧固件穿过设置于支撑部31的端部中的一个通孔K与对应的一个第二螺纹孔3223固定连接。这里，第二螺纹孔3223可以贯穿连接部322，也可以不贯穿连接部322。关于具有螺纹的紧固件的示例性结构可参考上述，在此不再赘述。
在一些实施例中，如图4A所示，支撑部31的远离背板组件2的表面在支撑部31的沿第一方向X的两个端部的每个端部处具有缺口槽。第二连接子部3222设置在该缺口槽中。
在一些示例中，如图4A所示，连接部322的远离背板组件2的表面和支撑部31的远离背板组件2的表面位于同一平面。在包边支架32和支撑部31组装后，连接部322的远离背板组件2的表面和支撑部31的远离背板组件2的表面构成支架组件3的一侧外表面，使得支架组件3的该侧外表面平整。这样，可将支架组件3的该侧外表面直接放在安装台上，利用支架组件3作为显示模组1和背板组件2的装配治具，减少额外的治具。
在一些实施例中，如图3所示，支撑部31的靠近背板组件2的表面为弧形表面，该弧形表面的弯曲边的延伸方向与第一方向X平行，且该弧形表面和翻边部321位于支架组件3的同一侧。基于此，该支撑部31可与曲面形状的背板组件2进行适配连接，使支架组件3可适用于曲面显示设备。
在一些示例中，如图4A所示，第一连接子部3221靠近背板组件2的表面为倾斜面，且该倾斜面和支撑部31的弧形表面中与该倾斜面靠近的边缘相切。这样，可使该倾斜面和弧形表面的边缘之间平滑过渡，不会出现锐利的过渡部位；相应地，在背板组件2和倾斜面与弧形表面的过渡部位接触时，背板组件2不会被过渡部位刮伤。
如图3所示，在一些实施例中，支撑部31包括至少两个支撑件311，所述至少两个支撑件311中的任意相邻两个支撑件311沿第二方向Y间隔设置。每个支撑件311的一端部通过至少一个可拆卸固定结构33与一个包边支架32固定，另一端部通过至少一个可拆卸固定结构33与另一个包边支架32固定。这里，两个包边支架32之间通过至少两个支撑件311连接，形成稳定的组件结构。
如图3所示，在一些示例中，支撑件311的形状为弓形，且该支撑件311的与背板组件2的远离显示模组1的表面接触的表面(为弧形表面。该弧形表面的弯曲边的延伸方向与第一方向X平行，且该弧形表面和翻边部321位于支架组件3的同一侧。
在此基础上，在一些示例中，如图3所示，支架组件3还包括至少一个支架34，每个支架34沿第二方向Y延伸。至少一个支架34设置在两个包边支架32之间，且至少一个支架34和至少两个支撑件311固定连接。系统电路组件4设置在相邻两个支撑件311和至少一个支架34围成的镂空区3A内。
在一些示例中，至少一个支架34包括两个支架34，两个支架34沿第一方向X间隔设置。系统电路组件4设置在相邻两个支撑件311和两个支架34围成的镂空区3A内。
在一些示例中，两个支架34中，其中一个支架34与对应的一个包边支架32的距离等于另一个支架34与对应的另一个包边支架32的距离。
在一些示例中，如图3所示，每个支撑件311上设置有至少一个散热窗口311A，所述至少一个散热窗口311A沿第二方向Y贯穿该支撑件311。一方面，通过设置散热窗口311A，可以使支撑件311在该处镂空，从而在不影响该支撑件311的结构性能的前提下，降低该支撑件311的重量。另一方面，散热窗口311A可以作为其他零部件的存放空间，增加支架组件3的存储能力。再一方面，散热窗口311A可以作为散热通道，加快热量散发的速度，增加支架组件3的散热能力。
在一些示例中，如图3所示，支架组件3的朝向背板组件2的表面上设置有多个安装孔35，所述多个安装孔35与翻边部321位于支架组件3的同一侧。示例的，多个安装孔35设置在支撑部31、支架34以及包边支架32上。如图9A和9B所示，背板组件2朝向支架组件3的支撑部31的一侧设置有多个凸起211，所述多个凸起211被配置为与所述多个安装孔35配合，使支架组件3和背板组件2能够快速定位。示例的，如图9B所示，多个凸起211与多个安装孔35一一对应，每个凸起211可以插入一个安装孔35之中，形成轴孔式定位关系。示例的，所述多个安装孔35均匀分布，相应的，多个凸起211均匀分布，使得支架组件3与背板组件2之间的连接力均匀分散，避免应力集中。
在一些实施例中，支撑部31、支架34以及包边支架32为钣金或注塑。
在一些实施例中，如图7和图8A所示，显示模组1还包括两个保护边框12。两个保护边框12设置于显示面板11沿第二方向Y相对设置的两侧边缘处，每个保护边框12和显示面板11的沿第二方向Y相对设置的两个侧面中的一个侧面固定。这样，在对显示面板11的侧面进行保护的基础上，可以减小或消除保护边框12和显示面板11的该侧面之间的缝隙，提高显示设备100的可靠性，保证显示设备100的外观美观。
示例的，保护边框12与显示面板11粘结固定。
在一些示例中，如图8A所示，保护边框12包括侧框121、与侧框121连接在一起的卡接部122、以及设置于卡接部122远离显示面板11的一侧的限位台123，卡接部122设置于显示面板11和背板组件2之间，侧框121与 显示面板11的侧面固定(侧框121粘结固定于显示面板11的侧面)。示例的，保护边框12的材料为弹性材料。卡接部122可以发生弹性变形，由此产生的弹性力使卡接部122固定在显示面板11和背板组件2之间。
背板组件2的边缘部分设置在该限位台123远离显示面板11的表面上，且背板组件2的位于该边缘部分的侧面与该限位台123的侧壁之间具有间隙dy。这样，可避免保护边框12和背板组件2之间发生挤压及造成保护边框12移位，进而保证保护边框12和显示面板11的侧面能够可靠接触。
在一些实施例中，如图7和图8A所示，显示模组1还包括至少一个第一驱动电路板13，所述至少一个第一驱动电路板13设置于显示面板11的沿第二方向Y相对设置的两侧边缘中的至少一侧边缘处。在一些示例中，如图7所示，显示模组1包括多个第一驱动电路板13，多个第一驱动电路板13设置于显示面板11的沿第二方向Y相对设置的两侧边缘中的一侧边缘处。在另一些示例中，显示模组1包括多个第一驱动电路板13，多个第一驱动电路板13中的部分设置于显示面板11的沿第二方向Y相对设置的两侧边缘中的一侧边缘处，多个第一驱动电路板13中的其余部分设置于显示面板11的沿第二方向Y相对设置的两侧边缘中的另一侧边缘处。
如图8A所示，每个第一驱动电路板13位于显示面板11的背面112，且超出显示面板11的边缘。第一驱动电路板13位于侧框121、卡接部122和显示面板11之间。这样，可保证第一驱动电路板13不会暴露在显示模组1之外，一方面可对第一驱动电路板13进行保护，另一方面保证显示模组1的外观整洁美观。
示例的，第一驱动电路板13包括第一薄膜131和设置于第一薄膜131上的源极驱动IC(Integrated Circuit，集成电路)132，源极驱动IC 132位于第一薄膜131远离显示面板11一侧。在固定第一驱动电路板13时，第一薄膜131的一端与显示面板11的背面112固定，其余部分伸出显示面板11外，然后反向折叠至显示面板11的背面112一侧。
在一些实施例中，如图7和8B所示，显示模组1还包括至少一个第二驱动电路板14，至少一个第二驱动电路板14设置于显示面板11的沿第一方向X相对设置的两侧边缘中的至少一侧边缘处。在一些示例中，显示模组1包括多个第二驱动电路板14，多个第二驱动电路板14设置于显示面板11的沿第一方向X相对设置的两侧边缘中的一侧边缘处。在另一些示例中，如图7所示，显示模组1包括多个第二驱动电路板14，多个第二驱动电路板14中的部分设置于显示面板11的沿第一方向X相对设置的两侧边缘中的一侧边缘 处，多个第二驱动电路板14中的其余部分设置于显示面板11的沿第一方向X相对设置的两侧边缘中的另一侧边缘处。
如图8B所示，每个第二驱动电路板14位于显示面板11的背面112，且第二驱动电路板14在背板组件2上的正投影位于显示面板11在背板组件2上的正投影范围内。第二驱动电路板14不会超出显示面板11的边缘，始终被显示面板11和背板组件2遮挡，不能从外侧观察到。基于此，无需在包边支架32的翻边部321设计相应的结构来对第二驱动电路板14进行遮挡和避让。示例的，第二驱动电路板14包括第二薄膜141和设置于第二薄膜141上的栅极驱动IC 142，栅极驱动IC 142位于第二薄膜141远离显示面板11一侧。在固定第二驱动电路板14时，第二薄膜141与显示面板11的朝向背板组件2的背面112固定。
在一些实施例中，如图10A和图11A所示，背板组件2包括背板21以及设置于背板21靠近显示面板11一侧表面的至少一个连接结构(以下为与其他连接结构区分，将该连接结构称为第一连接结构231)；显示面板11通过第一连接结构231与背板21固定。
在一些实施例中，如图13所示，显示设备100具有中心区101以及围绕中心区的边缘区102。相应地，如图10A和图11A所示，背板21具有背板中心区21A和背板边缘区21B，背板边缘区21B围绕背板中心区21A。背板中心区21A在与显示设备100的厚度方向垂直的一平面上的正投影与中心区101在该平面上的正投影完全重叠，背板边缘区21B在该平面上的正投影与边缘区102在该平面上的正投影完全重叠。在此情况下，第一连接结构231设置于背板21上且位于背板中心区21A。类似地，如图10B和图11B所示，显示模组1具有面板中心区11A和面板边缘区11B，面板边缘区11B围绕面板中心区11A。面板中心区11A在该平面上的正投影与中心区101在该平面上的正投影完全重叠，面板边缘区11B在该平面上的正投影与边缘区102在该平面上的正投影完全重叠。也就是说，面板中心区11A与背板中心区21A正对，面板边缘区11B与背板边缘区21B正对。这里，显示设备100的厚度方向包括显示面板11的出光面111指向背面112的方向以及背面112指向出光面111的方向。支架组件3的厚度方向与显示设备100的厚度方向平行。
在一些示例中，中心区101为显示设备100的显示区，边缘区102为显示设备100的周边区。在另一些示例中，中心区101的面积略小于 显示设备100的显示区，边缘区102为显示设备100的其他区域。在另一些示例中，中心区101的面积略大于显示设备100的显示区，边缘区102为显示设备100的其他区域。
在一些示例中，如图10B和11B所示，显示模组1还包括设置于显示面板11的背面112的控制电路板19；至少一个第一连接结构231设置于中心区101，控制电路板19设置于边缘区102(即，控制电路板19设置于显示面板11上且位于面板边缘区11B)。
在一些示例中，如图10A和图11A所示，背板组件2还包括设置于背板21靠近显示面板11一侧表面的绝缘片22，且绝缘片22在显示模组1上的正投影覆盖控制电路板19。绝缘片22可以使控制电路板19与背板21之间保持绝缘，在背板21为金属背板时，就可以避免控制电路板19与背板21发生短路，从而保证显示面板11的正常工作。
控制电路板19与上述的第一驱动电路板13和第二驱动电路板14连接。在一些示例中，控制电路板19为印刷电路板组件(Printed Circuit Board Assembly，PCBA)。示例的，PCBA包括印刷电路板(Printed Circuit Board，PCB)和设置于PCB上的时序控制器(Timing Controller，TCON)、电源管理集成电路(Power Management IC，PMIC)以及其它IC或电路等。
在一些示例中，如图10A和图11A所示，至少一个第一连接结构231包括多个第一连接结构231，且多个第一连接结构231呈阵列排布。
在一些示例中，第一连接结构231为磁吸结构，第一连接结构231被配置为使显示模组1与背板21吸附固定。在另一些示例中，第一连接结构231为粘结结构，第一连接结构231被配置为使显示模组1与背板21粘接固定。
在第一连接结构231为磁吸结构的情况下，示例的，第一磁吸件231为软磁片。软磁片是一种由磁性较弱的材料制成的板状结构，能够产生轻微的磁性吸附力，起到辅助固定作用。示例的，软磁片的材料包括橡胶等柔性材料。柔性材料性状柔软，缓冲作用较佳，因而，由柔性材料制成的第一连接结构231可防止对显示面板11造成冲击。在上述显示模组1和背板组件2组装过程中，由柔性材料制成的第一连接结构231，还有易于弯曲、与显示面板11更为贴合的优点。
在一些实施例中，如图10A和图11A所示，背板组件2还包括设置于背板21靠近显示面板11一侧表面的至少一个第二连接结构232，至少一个第二连接结构232设置在背板边缘区21B。在一些示例中，至少 一个第二连接结构232包括多个第二连接结构232，多个第二连接结构232间隔设置。在一些示例中，第二连接结构232为粘结结构。在另一些示例中，第二连接结构232为磁吸结构。在又一些示例中，多个第二连接结构232中的部分为粘结结构，部分为磁吸结构。
在第一连接结构231为磁吸结构，第二连接结构232为粘结结构的情况下，在对显示模组1和背板组件2进行组装时，首先通过第一连接结构231使显示模组1与背板21吸附固定而实现对位预装。由于显示模组1与背板21通过磁吸结构吸附固定，因而在该对位预装过程中可较容易地对显示模组1和背板21的相对位置进行调整，降低装配难度、提高装配精度。在显示模组1与背板21准确对位后，再利用多个第二连接结构232对显示面板11与背板21进行进一步固定。
这样，一方面，可保证显示模组1和背板21牢固的固定在一起。另一方面，相对于显示模组1和背板21通过整层的粘结层固定，可能会导致显示面板11的应力过大，使显示面板11破碎，本公开实施例中通过磁吸结构与粘结结构的配合可避免此问题。再一方面，由于磁吸结构在显示面板11与背板21间产生的磁吸力的方向主要沿法向(也就是显示设备100的厚度方向)分布，磁吸力在切向(也就是垂直于显示设备100的厚度方向的方向)上较弱，因而，显示设备100在运输过程，作用于显示面板11和背板21上的振动可以通过磁吸结构所在区域的显示面板11与背板21在切向上微小形变来吸收，从而可避免显示面板11损坏。
在一些示例中，背板21为金属背板。在一些示例中，背板21的材料包括铁(Fe)、钴(Co)、镍(Ni)元素及其合金，稀土元素及其合金，或锰(Mn)的化合物中的一种。
在第一连接结构231为磁吸结构，第二连接结构232为磁吸结构的情况下，在一些示例中，第一连接结构231的磁吸力小于第二连接结构232的磁吸力。这样，在保证显示模组1和背板21对位精确且可靠固定的情况下，可减少面板中心区11A的应力。尤其在曲面显示设备的组装过程中，将较大的磁吸力作用在面板边缘区11B，使显示面板11达到预定的整体弯曲弧度；而将较小的磁吸力作用在面板中心区11A，使显示面板11在面板中心区11A与背板21较好的贴合，从而达到预定的局部弯曲弧度，且弯曲过渡平滑。由此，显示面板11能够很好地弯曲到与曲面背板贴合的程度，且避免了面板中心区11A的应力集中和弯曲过度的情况， 保证组装过程中显示面板11不被损坏。
在第二连接结构232为磁吸结构的情况下，在一些示例中，第二连接结构232的材料包含金属。示例的，第二连接结构232的材料包括铁(Fe)、钴(Co)、镍(Ni)元素及其合金，稀土元素及其合金，或锰(Mn)的化合物中的一种。例如，第二连接结构232为钕铁硼磁铁。
在一些示例中，如图10A、图11A和图12所示，背板21中开设有多个点胶通孔212。点胶通孔212被配置为使胶体注入至背板21与显示模组1之间，以进一步固定显示模组1和背板21。
在一些示例中，如图14A所示，背板组件2还包括第一粘结层24。第一粘结层24具有两个粘接面，其中一个粘结面与背板21粘结，另一个粘结面与至少一个第一连接结构231粘结，以使第一连接结构231固定在背板21上。当然，如图14B和图14C所示，在背板组件2还包括第二连接结构232的情况下，第二连接结构232也通过第一粘结层24固定在背板21上。
示例的，至少一个第一连接结构231包括多个第一连接结构231，第一粘结层24包括多个第一粘结块，每个第一粘结块的一面与背板21粘结，每个第一粘结块的另一面与对应的一个第一连接结构231粘结。示例的，第一粘结层24可以是双面胶。又示例的，第一粘结层24还包括多个第二粘结块，每个第二粘结块的一面与背板21粘结，每个第二粘结块的另一面与对应的一个第二连接结构232粘结。
为保证第一连接结构231可靠的粘结在背板21，可使第一粘结层24与背板21之间的粘接力大于第一连接结构231与显示面板11之间的磁吸力。这样，可防止磁吸力使第一连接结构231与背板21分离。同理，可使第一粘结层24与背板21之间的粘接力大于第二连接结构232与显示面板11之间的磁吸力。
在一些实施例中，如图13所示，边缘区102包括沿第一方向X设置于中心区101相对两侧的两个第一边缘子区AA和沿第二方向Y设置于中心区101相对两侧的两个第二边缘子区BB。对应于上述的两个第一边缘子区AA和两个第二边缘子区BB，如图10A和图11A所示，背板边缘区21B也划分成沿第一方向X设置于背板中心区21A相对两侧的两个第一背板边缘子区21B1和沿第二方向Y设置于中心区101相对两侧的两个第二背板边缘子区21B2。每个第一背板边缘子区21B1在与显示 设备100的厚度方向垂直的一平面上的正投影与对应的一个第一边缘子区AA在该平面上的正投影完全重叠，每个第二背板边缘子区21B2在该平面上的正投影与对应的一个第二边缘子区BB在该平面上的正投影完全重叠。
上述多个第二连接结构232可分为第一组连接结构和第二组连接结构。第一组连接结构包括多个第二连接结构232中的部分，第二组连接结构包括多个第二连接结构232中的其余部分，且第一组连接结构和第二组连接结构中的第二连接结构232均为多个。在一些示例中，第一组连接结构设置于两个第一背板边缘子区21B1。即，第一组连接结构中的部分第二连接结构232设置于一个第一背板边缘子区21B1，其余第二连接结构232设置于另一个第一背板边缘子区21B1。第二组连接结构设置于两个第二背板边缘子区21B2。即，第二组连接结构中的部分第二连接结构232设置于一个第二背板边缘子区21B2，其余第二连接结构232设置于另一个第二背板边缘子区21B2。
基于此，多个第二连接结构232在两个第一边缘子区AA和两个第二边缘子区BB产生的磁吸附力分布较为均匀，使显示面板11与背板21在整个边缘区102都能较好地吸附固定，防止局部松开或翘起。
在一些示例中，如图10A和图11A所示，多个点胶通孔212中的部分点胶通孔212设置于一个第二背板边缘子区21B2，且该部分点胶通孔212沿第一方向X间隔排布，多个点胶通孔212中的剩余部分点胶通孔212设置于另一个第二背板边缘子区21B2，且该剩余部分点胶通孔212沿第一方向X间隔排布。这样在背板21弯曲时，沿第一方向X开设的多个点胶通孔212，也可以释放背板21因弯曲产生的应力，避免背板21的应力过大。
如图10B、图11B和图14B所示，在一些实施例中，显示模组1还包括两个辅助磁吸件15和第二粘结层16。该两个辅助磁吸件15设置在面板边缘区11B，且分别设置在面板中心区11A的相对两侧。第二粘结层16具有两个粘结面，其中一个粘结面与显示面板11的背面112粘结，另一个粘结面与该两个辅助磁吸件15粘结，以使辅助磁吸件15与显示面板11可靠固定。在此情况下，第二连接结构232为磁吸结构。
需要说明的是，图14B中仅示意了第二粘结层16的另一个粘结面与一个辅助磁吸件15粘结，另一个辅助磁吸件15的设置方式与图14B所 示的该一个辅助磁吸件15的设置方式相同。此外，由于该两个辅助磁吸件15分别设置在面板中心区11A的相对两侧，因而，第三粘结层16可仅设置在该两个辅助磁吸件15所在区域。
对应于上述的两个第一边缘子区AA和两个第二边缘子区BB，如图10B和图11B所示，面板边缘区11B也划分成沿第一方向X设置于面板中心区11A相对两侧的两个第一面板边缘子区11B1和沿第二方向Y设置于中心区101相对两侧的两个第二面板边缘子区11B2。每个第一面板边缘子区11B1在与显示设备100的厚度方向垂直的一平面上的正投影与对应的一个第一边缘子区AA在该平面上的正投影完全重叠，每个第二面板边缘子区11B2在该平面上的正投影与对应的一个第二边缘子区BB在该平面上的正投影完全重叠。
在一些示例中，如图10B和图11B所示，该两个辅助磁吸件15分别设置在两个第二面板边缘子区11B2中。第二组连接结构中位于每个第二背板边缘子区21B2中的所有第二连接结构232在显示面板11上的正投影，均位于对应的一个辅助磁吸件15在显示面板11上的正投影的范围内。该辅助磁吸件15被配置为与所述所有第二连接结构232磁性吸附。
第二粘结层16在辅助磁吸件15与显示面板11之间产生的粘接力大于辅助磁吸件15与第二连接结构232之间的磁吸力，防止该磁吸力使辅助磁吸件15与显示面板11分离，保证显示面板11与辅助磁吸件15之间连接的可靠性。在一些示例中，第二粘结层16可以是双面胶。
在一些示例中，辅助磁吸件15为金属片。示例的，该金属片的厚度大约为0.25～0.35mm，例如金属片的厚度为0.25mm、0.28mm、0.3mm、0.32mm、或0.35mm等。该金属片的厚度方向与显示设备100的厚度方向平行。
考虑到显示面板11中的金属层的厚度通常小于0.1mm，该金属层与第二连接结构232之间的磁性吸附力较小，因而通过设置辅助磁吸件15，可以使第二组连接结构中的第二连接结构232与该辅助磁吸件15以及显示面板11中的金属层之间形成的磁性吸附力更强，从而增大显示面板11与背板21之间的吸附力，使显示面板11与背板21之间的固定更为可靠。此外，通过合理设置辅助磁吸件15的厚度，对显示设备100厚度的影响可忽略，而且对于曲面显示装置，也不影响显示面板11的弯曲。
在一些示例中，如图10B和图11B所示，控制电路板19设置于一 第二面板边缘子区11B2中。在另一些示例中，至少一个第一驱动电路板13和控制电路板19设置于同一个第二面板边缘子区11B2中。在另一些示例中，至少一个第二驱动电路板14包括多个第二驱动电路板14，多个第二驱动电路板14中的部分设置于一个第一面板边缘子区11B1中，多个第二驱动电路板14中的其余部分设置于另一个第一面板边缘子区11B1中。
在一些示例中，如图15所示，该显示设备100还包括多个粘结结构23B，每个粘结结构23B位于一个点胶通孔212位置处，且位于两个辅助磁吸件15和背板21之间。通过将粘结材料点胶工艺注入点胶通孔212，可使粘结材料沿着点胶通孔212的边缘填充在显示面板11和背板21之前，从而在粘结材料固化后形成该粘结结构23B。
此处，粘结结构23B与显示面板11不发生直接接触，一方面避免对显示面板11的结构造成损伤，另一方面在需要将显示面板11与背板21进行分离时，可以直接切开粘结结构23B而不会伤及显示面板11，拆解安全便捷。
在一些示例中，粘结结构23B的材料包括中性透明玻璃胶。由于中性透明玻璃胶在涂覆至点胶通孔212的边缘后呈半液半固态，凝固需要一段时间，这样使得涂覆中性透明玻璃胶有一定容错度，可以在玻璃胶凝固之前调整涂覆位置。在中性透明玻璃胶凝固为粘结结构23B之后，粘结结构23B具有较强的粘性和一定的弹性，有利于显示面板11与背板21之间的固定。另外，当显示面板11需要从背板21上拆去时，可以加热该粘结结构23B，使其软化，再使用刀片等工具将粘结结构23B剥离，从而方便显示面板11从背板21上拆离，提高显示面板11的拆装维修的便利性。
在一些实施例中，如图10B和图14C所示，上述显示模组1还包括两个辅助连接结构17和第三粘结层18。该两个辅助连接结构17设置在面板边缘区11B，且分别设置在面板中心区11A的相对两侧。第三粘结层18具有两个粘结面，其中一个粘结面与显示面板11粘结，另一个粘结面与该两个辅助连接结构17粘结，以使辅助连接结构17与显示面板11可靠固定。需要说明的是，图14C中仅示意了第四粘结层18的另一个粘结面与一个辅助连接结构17粘结，另一个辅助连接结构17的设置方式与图14C所示的该一个辅助连接结构17的设置方式相同。此外，由于该两个辅助连接结构17分别设置在面板中心区11A的相对两侧，因 而，第三粘结层18可仅设置在该两个辅助连接结构17所在区域。
在一些示例中，如图10B所示，该两个辅助磁吸件15分别设置在两个第一面板边缘子区11B1。第一组连接结构中位于每个第一背板边缘子区21B1中的所有第二连接结构232在显示面板11上的正投影，均位于对应的一个辅助连接结构17在显示面板11上的正投影的范围内。该辅助连接结构17被配置为与位于该第一背板边缘子区21B1中的所有第二连接结构232磁性吸附。
第三粘结层18在辅助连接结构17与显示面板11之间产生的粘接力大于辅助连接结构17与第二连接结构232之间的磁吸力，防止该磁吸力使辅助连接结构17与显示面板11分离，保证显示面板11与辅助连接结构17之间连接的可靠性。在一些示例中，第四粘结层18可以是双面胶。
在一些示例中，辅助连接结构17为金属片。示例的，该金属片的厚度大约为0.25～0.35mm，例如0.25mm、0.28mm、0.3mm、0.32mm、或0.35mm等。该金属片的厚度方向与显示设备100的厚度方向平行。
考虑到显示面板11中的金属层的厚度通常小于0.1mm，该金属层与第二连接结构232之间的磁性吸附力较小，因而通过设置辅助连接结构17，可以使第一组连接结构中的第二连接结构232与该辅助连接结构17以及显示面板11中的金属层之间形成的磁性吸附力更强，从而增大显示面板11与背板21之间的吸附力，使显示面板11与背板21之间的固定更为可靠。此外，通过合理设置辅助连接结构17的厚度，对显示设备100厚度的影响可忽略，而且对于曲面显示装置，也不影响显示面板11的弯曲。
在一些实施例中，如图16所示，系统电路组件4的至少一个侧壁上具有多个外部接口411A。示例的，这些接口411A露出于显示设备100的外表面上，使用户可以将外部信号线的一端快速地连接到系统电路组件4上对应的接口411A上，外部信号线的另一端则可连接到如计算机主机、游戏机、移动通信设备等外部设备上的对应接口。示例的，这些接口可以包括USB(Universal Serial Bus，通用串行总线)、HDMI(High Definition Multimedia Interface，高清多媒体接口)、VGA(Video Graphics Array，视频图形阵列)、Thunderbolt(雷雳接口)等接口类型。
在一些示例中，如图3所示，至少一个支撑件311的远离背板组件2一侧开设有凹槽311C，该凹槽311C沿第二方向Y贯穿该支撑件311。该凹槽311C被配置为供外部信号线进入支架组件3内。
在一些示例中，如图16所示，系统电路组件4的一个侧壁上具有过线口411B，与显示模组1连接的内部信号线穿过过线口411B与系统电路组件4电连接。相应地，如图10A和图11A所示，背板组件2具有开口213，开口213被配置为使内部信号线穿过以与显示模组1电连接，便于内部信号线进行穿线布局。这里，系统电路组件4通过内部信号线向显示模组1提供信号，以使显示模组1进行显示。
在一些实施例中，如图16～17所示，系统电路组件4包括承载盒41、盒盖42和系统电路板43。承载盒41包括承载盒本体411以及设置于承载盒本体411至少相对两侧边缘处的多个固定部412；该多个固定部412伸出至承载盒本体411的外侧，且多个固定部412被配置为与支架组件3连接。示例的，承载盒本体411可以嵌入支架组件3的镂空区3A中，多个固定部412则与支架组件3进行连接。
盒盖42与承载盒41固定以形成容纳腔，系统电路板43设置在容纳腔内。在一些示例中，盒盖42上设置有多个散热孔421，对系统电路板43产生的热量进行散失，减少热量堆积及由此引起的温度上升。在一些示例中，承载盒41可以为分体或一体式结构。
在一些示例中，如图17所示，承载盒本体411包括底板4111、第一侧壁4112和第二侧壁4113。底板4111包括相对设置的第一边缘和第二边缘以及相对设置的第三边缘和第四边缘。第一侧壁4112和第二侧壁4113分别设置于第一边缘和第二边缘处，且第一侧壁4112和第二侧壁4113与底板4111连为一体。多个固定部412中的至少一个固定部412与第三边缘连为一体，多个固定部412中的其余固定部412与第四边缘连为一体。
在一些示例中，如图17所示，承载盒41还包括第三侧壁4114和第四侧壁4115，第三侧壁4114与第四侧壁4115分别设置于第三边缘和第四边缘处。位于第三边缘处的第三侧壁4114与第一侧壁4112和第二侧壁4113，和/或底板4111固定；位于第三边缘处的至少一个固定部412位于第三侧壁4114远离第四侧壁4115的一侧。位于第四边缘处的第四侧壁4115与第一侧壁4112和第二侧壁4113，和/或底板4111固定；位于第四边缘处的其余固定部412位于第四侧壁4115远离第三侧壁4114的一侧。在一些示例中，多个接口4111A设置在第四侧壁4115上。
在一些示例中，如图17所示，承载盒41还包括设置于第一侧壁4112和第二侧壁4113上的多个连接固定件413，多个连接固定件413被配置 为使盒盖42与第一侧壁4112和第二侧壁4113固定。示例的，连接固定件413为设有螺纹孔的固定片；盒盖42上设有过孔，螺栓的螺纹杆部穿过过孔后与固定片上的螺纹孔螺纹连接，通过螺栓的头部将盒盖42压紧于第一侧壁4112和第二侧壁4113上。示例的，多个连接固定件413的数量为4个，其中两个设置在第一侧壁4112的两端，另外两个设置在第二侧壁4113的两端，以使4个连接固定件413位于承载盒41的4个角位置处。示例的，多个连接固定件413焊接在第一侧壁4112和第二侧壁4113上。
