背景技术
随着折叠形态整机的出现，弯折区形状的差异化探索越来越多。目前主流的弯折区形态主要有两种，即，U形弯折(U shape)和水滴形弯折(Water-drop shape)。水滴形弯折主要用于显示器向内折叠的整机设计中，相对于U形弯折而言，水滴形弯折能为整机的其他组件提供更大的有效空间，从而利于内折设备的轻薄化。
水滴形弯折的形状几何设计方面更为复杂，柔性显示模组堆叠结构中应变及应力的分布也更复杂。这种形状本身对折叠显示模组的设计提出了更高的要求。例如，由于主弯折区与水滴形弯折区实质上为相邻的反向弯折区，区域交界位置容易产生应力集中，造成柔性显示模组粘结层开胶的问题。
发明内容
本发明旨在至少解决现有技术中存在的技术问题之一。为此，本发明提出一种用于显示模组的支撑件，所述用于显示模组的支撑件可以实现局部区域的弯折信赖性，实现弯折区应力分散、支撑性提升及弯折后的回复能力，并且，可以在实现不同弯折半径和相反弯折方向形变的同时，有效降低水滴形弯折区域的水平应力集中，解决显示模组叠层结构开胶问题。

具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本发明，而不能理解为对本发明的限制。
下面参考附图描述根据本发明第一方面实施例的用于显示模组的支撑件10。显示模组在折叠状态和展开状态之间可切换，支撑件10位于显示模组的柔性显示面板的背光侧。
如图1-图5和图12所示，根据本发明实施例的用于显示模组的支撑件10，包括：第一弯折区100、第二弯折区200和平面区300。
具体而言，第二弯折区200为多个，多个第二弯折区200分布于第一弯折区100的相对两侧，例如，第二弯折区200为两个，两个第二弯折区200分别位于第一弯折区100的左侧和右侧。平面区300为多个，多个平面区300分布于第二弯折区200的远离第一弯折区100的一侧，例如，平面区300为两个，一个平面区300位于左侧的第二弯折区200的左侧，另一个平面区300位于右侧的第二弯折区200的右侧。可以理解，这里的平面区300是相对于弯折区而言的。
其中，显示模组在折叠状态时，第一弯折区100的弯折方向和第二弯折区200的弯折方向相反，即，第一弯折区100在弯折时的弯折方向和第二弯折区200在弯折时的弯折方向相反，例如，第一弯折区100向内弯折，第二弯折区200为向外弯折。这里，向内可以理解为朝向折叠状态下显示模组的内部，向外可以理解为朝向折叠状态下显示模组的外部，例如，第二弯折区200和平面区300分别为两个，显示模组在折叠状态下，第一弯折区100的在未折叠时的左右两侧在上下方向上相对，两个第二弯折区200在上下方向上相对且两个平面区300在上下方向上相对，第一弯折区100、两个第二弯折区200和两个平面区300所围的空间即构成显示模组的内部空间，此时，第一弯折区100的弯折轴位于显示模组的内部，第二弯折区200的弯折轴位于显示模组的外部。第一弯折区100(对应主弯折区)弯折半圆的弧顶对应显示模组的弯折轴，第二弯折区200对应水滴形弯折区。
第一弯折区100、第二弯折区200和平面区300中的至少一个上设有弹性孔11，弹性孔11为多组，多组弹性孔11沿第一方向(例如图5示出的方向A)排列,每组包括多个弹性孔11,每组中的多个弹性孔11沿第二方向(例如图5示出的方向B)排列，第一方向和第二方向不同，第一方向与第二方向可以相互垂直也可以彼此倾斜。例如，弹性孔11为通孔(贯穿支撑件)或半通孔(例如为槽)。也就是说，可以在第一弯折区100、第二弯折区200和平面区300中的一个区域上设置多个弹性孔11，也可以在第一弯折区100、第二弯折区200和平面区300中的两个区域上分别设置多个弹性孔11，或者第一弯折区100、第二弯折区200和平面区300中的每一区域都设置多个弹性孔11，多个弹性孔11排列成网格状，以实现图案化设计。可以理解，不同区域的弹性孔11图案化分布设计可以相同也可以不同。
由此，用于显示模组的支撑件10使用分区域设计的图案化设计，适应主弯折区、水滴形弯折区、平面区300的不同支撑及耐弯折需求，匹配不同弯折半径及不同几何形状。
根据本发明实施例的用于显示模组的支撑件10，局部区域图案化可以实现局部区域的弯折信赖性，实现弯折区应力分散、支撑性提升及弯折后的回复能力，并且，通过不同的图案设计及相邻两区域的图案化设计匹配设计，可以在实现不同弯折半径和相反弯折方向形变的同时，有效降低水滴形弯折区域的水平应力集中，解决显示模组叠层结构开胶问题。
根据本发明的一些实施例，如图12所示，第一弯折区100与第二弯折区200之间设有过渡区12，过渡区12为实体件，从而可以在实现不同弯折半径和相反弯折方向形变的同时，更加有效地降低水滴形弯折区域的水平应力集中、解决显示模组叠层结构 开胶问题。其中，第一弯折区100的弹性孔11的形状、大小和排布方式与第二弯折区200的弹性孔11的形状、大小和排布方式相同。
根据本发明的一些实施例，第一弯折区100、第二弯折区200和平面区300可以为一体金属件，从而结构简单、支撑强度高，弯折后的回复能力强，能够更好地解决应力集中和显示模组叠层结构开胶问题。这里，用于显示模组的支撑件10可以为硬质金属，例如不锈钢、钛、镁、铝及其他金属的合金。
根据本发明的一些实施例，弹性孔11内可以填充有柔性件，以降低孔局部的应力集中。柔性件可以由高分子材料制成，例如，柔性件为橡胶件、硅胶件、PU件。
在本发明的一些具体实施例中，柔性件的厚度为0.001mm-0.5mm，以在保证一定弹性的同时保证表面平整度。
根据本发明的一些实施例，弹性孔11的形状可以为圆形、椭圆形、矩形、圆弧端矩形和多边形中的任一种。其中，圆弧端矩形孔是指长圆形孔，即，孔为长条形，孔的两端部轮廓为圆弧形，孔的两端之间的轮廓部分为直线形。可以理解，不同区域的弹性孔11的形状可以相同或不同，同一区域的多个弹性孔11的形状可以相同或不同，本领域技术人员可以根据实际弯折和支撑需求进行合理调整。
在本发明的一个具体实施例中，如图5所示，第一弯折区100的弹性孔11的形状和第二弯折区200的弹性孔11的形状完全相同，且均为圆弧端矩形通孔。
根据本发明的一些实施例，第一弯折区100、第二弯折区200和平面区300的形状分别为矩形、椭圆形和多边形中的任一种，可以理解，第一弯折区100、第二弯折区200和平面区300的形状可以彼此相同或不同，多个第二弯折区200的形状可以相同或不同，多个平面区300的形状可以相同或不同。
如图6-图11所示，根据本发明第二方面实施例的用于显示模组的支撑组件30，包括：根据本发明第一方面实施例所述的用于显示模组的支撑件10和补强件400。
具体而言，补强件400位于支撑件10的背向显示模组的柔性显示面板的一侧，即，支撑件10位于补强件400与柔性显示面板之间。补强件400包括第一补强片410和第二补强片420，第一补强片410和第二补强片420分别与支撑件10的背面相连。
如图7所示，显示模组在展开状态时第一补强片410的朝向支撑件10的一侧表面和第二补强片420的朝向支撑件10的一侧表面位于同一平面内以至少支撑第一弯折区100。这里，“至少支撑第一弯折区100”是指，显示模组在展开状态时，支撑件10和补强件400分别展平，此时，第一弯折区100的水平投影与补强件400的水平投影至少部分重合，使得补强件400对展平的第一弯折区100起到支撑作用；当然，补强片还可以为第一弯折区100以外的弯折区域提供支撑，可以通过调整补强片与支撑件 10的连接位置实现。
如图6所示，显示模组在折叠状态时第一补强片410与第二补强片420张开且第一补强片410的朝向支撑件10的一侧表面和第二补强片420的朝向支撑件10的一侧表面相对。这里，第一补强片410的朝向支撑件10的一侧表面和第二补强片420的朝向支撑件10的一侧表面相对，包括第一补强片410的朝向支撑件10的一侧表面和第二补强片420的朝向支撑件10的一侧表面正对、第一补强片410的朝向支撑件10的一侧表面和第二补强片420的朝向支撑件10的一侧表面错开、第一补强片410的朝向支撑件10的一侧表面和第二补强片420的朝向支撑件10的一侧表面相互平行以及第一补强片410的朝向支撑件10的一侧表面和第二补强片420的朝向支撑件10的一侧表面彼此倾斜这些情形。例如，在折叠或展平过程中，支撑件10带动第一补强片410和第二补强片420张开或展平，支撑件10折叠时补强片张开。
根据本发明实施例的用于显示模组的支撑组件30，利用如上所述的用于显示模组的支撑件10，可以实现局部区域的弯折信赖性，实现弯折区应力分散、支撑性提升及弯折后的回复能力，并且，可以在实现不同弯折半径和相反弯折方向形变的同时，有效降低水滴形弯折区域的水平应力集中，解决显示模组叠层结构开胶问题；此外，第一补强片410和第二补强片420不仅能够提高弯折区域的平坦度及支撑性，同时对弯折区域展平时的抗冲击能力也有增强的作用。
根据本发明的一些实施例，如图6所示，补强件400与支撑件10的连接处位于第一弯折区100与第二弯折区200之间，即，第一补强片410与支撑件10的连接处位于第一弯折区100与第二弯折区200之间，和/或，第二补强片420与支撑件10的连接处位于第一弯折区100与第二弯折区200之间。例如，第一补强片410与支撑件10的连接处、第二补强片420与支撑件10的连接处布置在第一弯折区100的相对两侧，当第一弯折区100与第二弯折区200之间设有过渡区12时，第一补强片410和第二补强片420可以分别与两侧的过渡区12相连，以补充弯折区的支撑性和抗冲击能力。
根据本发明的一些实施例，如图9和图10所示，显示模组在展开状态时第一补强片410与第二补强片420形状配合，即，第一补强片410和第二补强片420拼接，从而利于折叠和展开，利于提高支撑性和抗冲击能力。
在本发明的一些实施例中，显示模组在展开状态时第一补强片410与第二补强片420之间的配合间隙小于10mm，以保证支撑性和抗冲击能力。进一步地，显示模组在展开状态时第一补强片410与第二补强片420之间的配合间隙小于等于2mm。
根据本发明的一些实施例，第一补强片410和第二补强片420中的每一个的厚度为0.05mm-0.5mm，以保证足够的支撑性，并减小折叠时占用的收纳空间。
根据本发明的一些实施例，如图8所示，补强件400与支撑件10之间设有柔性缓冲层500。也就是说，第一补强片410和第二补强片420中的至少一个与支撑件10之间设有柔性缓冲层500。例如，第一补强片410与支撑件10之间、第二补强片420与支撑件10之间分别设有柔性缓冲层500，柔性缓冲层500固定在支撑件10的背面，且柔性缓冲层500与第一弯折区100位置对应，以补充补强件400和支撑件10之间的间隙，提高可靠性。
根据本发明的一些实施例，如图11所示，第一补强片410和第二补强片420中的至少一个由多个子补强片401顺次相连所构成。可以理解，多个子补强片401可以通过固定轴彼此连接。例如，第一补强片410和第二补强片420分别由多个子补强片401顺次相连所构成，这样，在折叠状态下可以具有更小的收纳空间。在本发明的一些具体实施例中，补强件400和支撑件10可以为金属件，例如为不锈钢件、铝合金件、镁合金件、钛合金件。补强件400与支撑件10之间的固定方式可以是通过粘结层粘接或金属铆接或焊接。
根据本发明第三方面实施例的显示模组1，包括：根据本发明第一方面实施例所述的用于显示模组的支撑件10和柔性显示面板20。或者，根据本发明第三方面实施例的显示模组1，包括：根据本发明第二方面实施例所述的用于显示模组的支撑组件30和柔性显示面板20。
具体而言，柔性显示面板20为顶发射结构，第一弯折区100、第二弯折区200和平面区300分别贴合于柔性显示面板20的背光面(非发光面)。例如，柔性显示面板20为OLED面板。由此，对水滴形弯折结构进行分区(主弯折区、水滴形弯折区、平面区300)图案化设计，以匹配不同分区的弯折状态。
根据本发明实施例的显示模组1，利用如上所述的用于显示模组的支撑件10，可以实现局部区域的弯折信赖性，实现弯折区应力分散、支撑性提升及弯折后的回复能力，并且，可以在实现不同弯折半径和相反弯折方向形变的同时，有效降低水滴形弯折区域的水平应力集中，解决显示模组叠层结构开胶问题。
根据本发明实施例的显示模组1的其他构成以及操作对于本领域普通技术人员而言都是已知的，这里不再详细描述。
