支撑构件包括第一支撑板2、第一粘接层5和第二支撑板3，第二支撑板3通过第一粘接层5粘接于第一支撑板2的一侧。其中，第一支撑板2为柔性板，第一支撑板2包括第一可变形区21，第一可变形区21设有多个开孔4，第一可变形区21与显示面板1的弯折区12的形状匹配，二者贴合并通过第一粘接层5固定在一起。第二支撑板3设于第一支撑板2背离显示面板1的一侧，第二支撑板3的刚性大于第一支撑板2，也就是说，第二支撑板3相比于第一支撑板2而言不易弯折。第二支撑板3包括第二可变形区31，第二可变形区31与第一可变形区21贴合并通过第一粘接层5固定在一起。
参考图1，第一支撑板2还可以包括第一平面区22，由于第一支撑板2为柔性板，该第一平面区22仅指在使用过程中呈平面形态，实际上也可以进行弯折。第二支撑板3也可以包括第二平面区32，由于第二支撑板3相对刚性较强，该第二平面区32是指在使用过程中或无外力作用下都呈平面形态。
需要说明的是，第一支撑板2为柔性板，当显示面板的弯折区12在弯折过程中，第一支撑板2的第一可变形区21可以对应改变形态；例如，显示面板的弯折区12可以具有展平状态，此时弯折区12和平面区11位于同一平面内，第一支撑板2整体也形成平板结构，即显示面板的第一可变形区21也呈平板状。显示面板的弯折区12还可以具有弯折状态，例如沿曲线延伸，此时弯折区12和平面区11位于不同平面内，相应的，第一支撑板2的第一可变形区21也沿曲线延伸呈弯折状。第二支撑板3相对于第一支撑板2而言刚性较强，不易弯折，是指在使用过程中能够保持较稳定的形态(平面或弧面)，确保给显示面板1提供稳定的支撑。其第二可变形区31通过机械加工形成，因此并非完全不能够弯折，实际上在较大外力下也能够弯折，以便可以经过冲压等机械加工形成第二可变形区31。
该支撑构件设置了双层支撑板，第二支撑板3具有刚性，对显示面板起主要的支撑作用。第一支撑板2具有柔性，设置在第二支撑板3和显示面板1之间，可以弯折形成弧面形态，对显示面板弯折区12起到一定的支撑作用，粘接为一体的双层支撑板整体结构能够提高支撑效果。由于第二支撑板3刚性较强，弯折时回弹力较大，第一支撑板2的第一可变形区21上设置的开孔可释放双层支撑板整体的形变应力，将双层支撑板整体变形产生的回弹力分解，使得双层支撑板整体的回弹力减小，可以防止第一支撑板2因回弹和第二支撑板3之间产生分层，提高弯折区12的结构稳定性，进而提高产品的生产和良率。
本公开中，第一支撑板2和第二支撑板3之间通过第一粘接层5粘接在一起。第一粘接层5可以为光学胶等粘性材料。可以理解的是，第一粘接层5的粘性材料具有可弯折性，以便配合第一支撑板2和第二支撑板3进行弯折。
第一支撑板2和第二支撑板3可以均为金属板，例如均为不锈钢板，第一支撑板2厚度较薄，以便能够弯折，第二支撑板3的厚度较厚，刚性较强。作为优选，第一支撑板2的厚度小于或等于50μm，进一步地，第一支撑板2的厚度30μm＜h＜50μm，该范围的第一支撑板2能够兼顾支撑强度和弯折性能的要求。作为优选，第二支撑板3的厚度大于或等于100μm，进一步地，第一支撑板2的厚度100μm＜h＜300μm，该范围的第二支撑板3能够兼顾支撑强度和模组整体厚度的要求。
本公开中，第一可变形区21在第一支撑板2的位置以及第二可变形区31在第二支撑板3的位置根据显示面板1中弯折区12的位置来确定。显示面板1的弯折区12可以位于平面区11的至少一侧。参考图1，为一种双向弧面的显示面板1，即该显示面板1的中央显示部分为一整个平面区11，左右两侧各设置有一个弯折区12，例如沿图中第一方向弯折，即图中水平方向。对应的，第一支撑板2的中央部分为第一平面区22，第一可变形区21位于第一平面区22的左右两侧；第二支撑板3的中央部分为第二平面区32，第二可变形区31位于第二平面区32的左右两侧，且第一可变形区、第二可变形区的弯折方向与弯折区12的弯折方向一致。参考图4，为一种单向弧面的显示面板1的俯视图，图5为图4中B-B向的截面示意图。图5中N区的放大图也参考图3。该显示面板1的中央显示部分为一整个平面区11，其右侧设置有一个弯折区12。对应的，第一支撑板2的中央部分为第一平面区22，第一可变形区21位于第一平面区22的右侧。第二支撑板3的中央部分为第二平面区32，第二可变形区31位于第二平面区32的右侧。图1和图4所示的显示面板1中，弯折区12均设于显示面板1的边缘，第一可变形区21、第二可变形区31分别位于第一平面区22、第二平面区32的边缘。显示面板1可以为曲面显示面板，也可以为滑卷、卷轴等存在弧面区的柔性显示面板。在其他实施方式中，弯折区12还可以位于平面区11的四周。在一种实施方式中，显示面板1还可以为可折叠的显示面板1，该显示面板1可以包括多个平面区11，各相邻平面区11之间设置弯折区12，以便进行折叠。对应的，第一支撑板2、第二支撑板3也可以分别包括多个第一平面区22、第二平面区32，第一可变形区21、第二可变形区31分别设置 在相邻的第一平面区22之间、相邻的第二平面区32之间。总而言之，无论弯折区12设于显示面板1的什么位置，支撑板都可以在对应位置设置弧面区，并且通过双层结构提高柔性显示面板1的支撑效果，同时防止显示面板弯折区12因为回弹性较大与第二支撑板3分离，进而提高产品的生产和良率。
如图2-图4所示，本公开中，第一支撑板2上的开孔4为贯穿第一支撑板2的通孔。由此，第一支撑板2和第二粘接层6之间的第一粘接层5会在开孔4处向上溢出，进一步可以粘接在显示面板1上，使得显示面板1和第二支撑板3之间连接更为牢固，避免发生分层现象。当然，在其他实施方式中，开孔4也可以为设置在第一支撑板2上表面或下表面的盲孔，第一粘接层5或第二粘接层6在制备过程中会在开孔4处溢出，最终“抓”在第一支撑板2或第二支撑板3上，也可以提高模组弯折部分的整体结构稳定性。
参考图6，开孔4包括条形开孔，条形开孔的延伸方向与第一可变形区、第二可变形区的弯折方向一致，即沿第一方向延伸，第一方向与显示面板弯折区12的弯折方向一致，即图中水平方向。多个条形开孔沿第二方向，即图中纵向方向间隔排列。水平方向的条形开孔能将第一可变形区21的应力沿弯折方向释放，能够有效释放应力。
在另一种实施例中，开孔4还包括沿纵向延伸的条形开孔，多个沿纵向延伸的条形开孔沿水平方向间隔排列，两个方向的多个条形开孔相交呈网格状(图中未示出)。网格状的条形孔能将第一可变形区21的应力沿弯折方向和其他方向同时释放，能够起到更好的释放效果。
在其他实施方式中，开孔4的形状包括但不限于条形，还可以为图6所示的圆形、矩形、菱形、六边形等任意规则或不规则的形状。多个开孔4阵列排布在第一支撑板2的第一可变形区21，也能够均匀释放第一可变形区21的应力。
本公开还提供一种包含上述支撑构件的显示模组，如图所示，支撑构件设置在显示面板1的背光侧，且第一支撑板2的第一可变形区21与显示面板1的弯折区12贴合，形成显示模组。其中，第一支撑板2和显示面板1之间可以设置第二粘接层6，以将二者粘接在一起。显示 面板1、第一支撑板2、第二支撑板3两两贴合且粘接在一起，由于第一支撑板2的第一可变形区21设置有开孔，可释放双层支撑构件和显示面板的形变应力，将双层支撑构件和显示面板整体变形产生的回弹力分解，减小双层支撑构件与显示面板整体的回弹力，从而避免显示面板1与双层支撑构件分离。
第二粘接层6的材料可以与第一粘接层5相同，也可以不同，例如可以为光学胶等粘性材料。可以理解的是，第二粘接层6的材料也具有可弯折性，以便配合显示面板进行弯折。
由于第一支撑板2上设置有开孔4，且开孔4为贯穿第一支撑板2的通孔，制作过程中第一粘接层5会在开孔4处向上溢出，并与第二粘接层6粘接为一体，第一粘接层5和第二粘接层6将第一支撑板2“包裹”在其中，也提高了模组弯折部分的整体结构稳定性，避免显示面板1和支撑构件发生分层现象。同理，在制作第二粘接层6时，第二粘接层6也会在开孔4处向下溢出，并与第一粘接层5粘接为一体。
如前所述，显示模组中的显示面板可以为曲面显示面板，也可以为滑卷、卷轴等存在弧面区的柔性显示面板。基于支撑构件的支撑，本公开显示模组能够提高产品的良率及产品开发的成功率，也能够保证柔性产品的形态，满足设计需求。
本公开实施方式还提供一种显示装置，该显示装置包括上述实施方式的显示模组。由于该显示装置包括上述显示模组，因此具有相同的有益效果，本公开在此不再赘述。
本公开对于显示装置的适用不做具体限制，其可以是电视机、笔记本电脑、平板电脑、可穿戴显示设备、手机、车载显示、导航、电子书、数码相框、广告灯箱等任何具有柔性显示功能的产品或部件。
本领域技术人员在考虑说明书及实践这里公开的发明后，将容易想到本公开的其它实施方案。本申请旨在涵盖本公开的任何变型、用途或者适应性变化，这些变型、用途或者适应性变化遵循本公开的一般性原理并包括本公开未公开的本技术领域中的公知常识或惯用技术手段。说明书和实施例仅被视为示例性的，本公开的真正范围和精神由所附的权利要求指出。
