本文参照作为理想化示例性附图的剖视图和/或平面图描述了示例性实施方式。在附图中，为了清楚，放大了层的厚度和区域的面积。因此，可设想到由于例如制造技术和/或公差引起的相对于附图的形状的变动。因此，示例性实施方式不应解释为局限于本文示出的区域的形状，而是包括因例如制造而引起的形状偏差。例如，示为矩形的蚀刻区域通常将具有弯曲的特征。因此，附图中所示的区域本质上是示意性的，且它们的形状并非旨在示 出设备的区域的实际形状，并且并非旨在限制示例性实施方式的范围。
参考图1A、图1B和图2，本公开的实施例提供了一种显示装置1000，从显示装置1000的发光类型上看，上述显示装置1000可以是主动发光显示装置，例如OLED(OrganicLight-Emitting Diode，有机发光二极管)显示装置、QLED(Quantum Dot Light Emitting Diodes，量子点电致发光)显示装置或者MLED(Mini/Micro Light Emitting Display，微型发光二极管)显示装置等。从显示装置1000的形状上看，上述显示装置1000可以是矩形或圆形等。本公开的实施例对此不做具体限定。
下面以显示装置为矩形作为示例，对本公开的一些实施例进行示意性说明，但是本公开的实施方式不限于此，并且也可以考虑任何其它显示装置，只要应用相同的技术思想即可。
显示装置1000为具有图像显示功能的产品。示例性地，显示装置1000可以是显示不论运动(例如，视频)的还是固定(例如，静止图像)的且不论文字的还是图像的任何装置。示例性地，该显示装置1000可以为平板电脑、车载显示器、飞行显示器等任何具有显示功能的产品或者部件。如图2所示，显示装置1000为可折叠的显示装置，例如折叠手机，图2示出了折叠手机的背面。
如图1A和图1B所示，显示装置1000包括显示模组1，以及设于显示模组1的出光侧的盖板2。在显示装置1000可折叠的显示装置的情况下，显示模组1包括支撑结构10和显示面板30。
其中，显示面板30包括至少两个第一显示部L1和至少一个第二显示部L2，一个第二显示部L2设于相邻两个第一显示部L1之间且与相邻两个第一显示部L1连接，第二显示部L2可弯折。支撑结构10被配置为支撑显示面板30，支撑结构10设于显示面板30的背光侧，包括与至少两个第一显示部L1分别对应设置的至少两个第一支撑部M1，和与至少一个第二显示部L2对应设置的至少一个第二支撑部M2。
显示面板30具有柔性。支撑结构10的材料包括具有刚性的材料，例如为不锈钢(SUS)、钛合金或者碳纤维等，支撑结构10还可以包括其他刚性材料只需满足起到支撑显示面板的作用即可。
设置于显示面板30的第一显示部L1背光侧的第一支撑部M1用于支撑对应的第一显示部L1。第二支撑部M2包括折叠结构以使得第二支撑部M2可弯折，通过弯折第二支撑部M2，可以使得第二支撑部M2两侧相连的两个第一显示部L1重合或展开，从而使得显示装置1000获得折叠、展开等状态。
例如，如图1A、图1B和图2所示，显示面板30包括两个第一显示部L1和一个第二显示部L2，一个第二显示部L2设于相邻两个第一显示部L1之间且与相邻两个第一显示部L1连接，第二显示部L2可弯折。支撑结构10包括与两个第一显示部L1分别对应设置 的两个第一支撑部M1，和与一个第二显示部L2对应设置的一个第二支撑部M2，通过弯折第二显示部L2，显示面板30可以呈现弯折状态、展开状态或者介于弯折状态和展开状态之间两个第一显示部L1具有夹角的状态。
例如，显示面板30还可以包括三个第一显示部L1和两个第二显示部L2，一个第二显示部L2设于相邻两个第一显示部L1之间且与相邻两个第一显示部L1连接，任一的第二显示部L2均可弯折。支撑结构10包括与三个第一显示部L1分别对应设置的三个第一支撑部M1，和与两个第二显示部L2对应设置的两个第二支撑部M2，通过弯折任一的第二显示部L2，与弯折的第二显示部L2连接两个第一显示部L1可以呈现弯折状态、展开状态或者介于弯折状态和展开状态之间两个第一显示部L1具有夹角的状态；通过弯折两个第二显示部L2，显示面板30可以呈现三折状态、展开状态或者介于弯折状态和展开状态之间的状态。
例如，显示面板30还可以包括多个第一显示部L1和多个第二显示部L2，一个第二显示部L2设于相邻两个第一显示部L1之间且与相邻两个第一显示部L1连接，任一的第二显示部L2均可弯折。支撑结构10包括与多个第一显示部L1分别对应设置的多个第一支撑部M1，和与多个第二显示部L2对应设置的多个第二支撑部M2，不做限定。
盖板2为透明盖板，被配置为支撑保护显示模组1，并保证显示模组1在受到撞击或刮蹭时仍能保持良好的显示效果。盖板2也具有柔性，以配合显示模组1的折叠、展开等状态。
在一些实施例中，盖板2包括至少一层有机材料。
示例性地，参考图1A，盖板2为单层，单层盖板的材料可以包括聚酰亚胺(Polyimide，简称：PI)或者聚对苯二甲酸乙二醇酯(Polyethylene terephthalate，简称：PET)。
示例性地，参考图1B，盖板2还可以为多层，盖板2为多层时，包括：依次层叠设置的第一盖板子层201、盖板胶层202和第二盖板子层203，第二盖板子层203设置在远离显示模组1的一侧。
例如，第一盖板子层201的材料包括：聚酰亚胺(Polyimide，简称：PI)或者超薄柔性玻璃。
例如，盖板胶层202的材料包括：为无色透明、高透过率、胶结强度良好的光学胶，(Optically Clear Adhesive，简称：OCA)，光学胶的粘结强度较高，且具有较高的透明度，不会影响显示模组的显示效果。
例如，第二盖板子层203的材料包括：聚对苯二甲酸乙二醇酯(Polyethylene terephthalate，简称：PET)。
目前，为了使显示装置1000实现较高的屏占比，可以在显示装置1000的显示区域中设置通孔，进而可以在通孔中设置摄像头等器件。参考图3，图3为图2中的显示装置1000 在虚线圈S处的放大图，显示装置1000包括显示区Q1、孔边区Q2和通孔区Q3，显示区Q1中设有子像素，用于进行画面显示；摄像头位于通孔区Q3；孔边区Q2位于显示区Q1和通孔区Q3之间且围绕通孔区Q3，孔边区Q2为围绕通孔区Q3的环形。可以理解的是，对于可折叠的显示装置1000，每个第一显示部L1均包括显示区Q1的一部分，每个第二显示部L2也均包括显示区Q1的一部分。
其中，孔边区Q2为显示区Q1和通孔区Q3之间的过渡区域，孔边区Q2未设置子像素，因此并不能用于显示。孔边区Q2用于设置对显示区Q1进行封装的相关结构，例如阻挡坝，以防止水氧经由通孔区Q3进入显示区Q1内部，对显示区Q1中的子像素、电路、信号线等结构造成腐蚀。
可以理解的是，图3中以孔边区Q2为圆环形为例进行示意，然而孔边区Q2的形状不限于环形，其可以是任意的形状，且其边界不一定平直或圆滑延伸，其边界可以是以不规则的形状延伸。在一些实施例中，孔边区Q2的形状依通孔区Q3的形状而定，当通孔区Q3为圆形时，孔边区Q2为圆环形，当通孔区Q3为矩形时，孔边区Q2为方框形，当通孔区Q3为跑道形时，孔边区Q2为跑道形。
结合参考图2、图3和图4，图4为图3中的显示装置沿AA向的局部结构的剖视图，显示模组1中，显示面板30的至少一个第一显示部L1具有贯穿第一显示部L1的第一通孔H1，支撑结构10的至少一个第一支撑部M1具有贯穿第一支撑部M1的第二通孔H2,第一通孔H1和第二通孔H2相贯通，用于放置显示装置1000的摄像头。
为了避免摄像头与支撑结构10形成干涉，设置第二通孔H2的边界位于第一通孔H1的边界外侧，也就是说显示面板30的第一显示部L1的部分相比支撑结构10的第一支撑部M1向外延伸，但由于支撑结构10一般选用刚性结构，显示装置1000中的盖板2为柔性盖板，显示面板30也为柔性面板，柔性盖板的机械性能较差，柔性盖板无法保护显示面板，显示面板30在受到外界挤压或跌落冲击时，由于延伸出来的显示面板30的第一显示部L1的底部没有支撑结构10的支撑，显示面板30就会在支撑结构10的第二通孔H2的边缘集中受压，导致应力集中进而引发显示面板30破裂，最终导致显示装置1000出现黑斑，如图3所示。因此，显示模组1的抗挤压和抗冲击的机械能力亟待解决。
为解决上述技术问题，参考图5，在一些实施例中，提供一种显示模组1。显示模组1包括：显示面板30和支撑结构10。显示面板30可折叠，其至少一个第一显示部L1具有贯穿第一显示部L1的第一通孔H1。支撑结构10可折叠，其至少一个第一支撑部M1具有贯穿第一支撑部M1的第二通孔H2，第一通孔H1和第二通孔H2相贯通；第一通孔H1的边界位于第二通孔H2的边界外侧，或第一通孔H1的边界与第二通孔H2的边界重合。
本公开实施例提供的显示模组1，通过设置第一通孔H1的边界位于第二通孔H2的边界外侧，或第一通孔H1的边界与第二通孔H2的边界重合，这样，相比于，第二通孔H2 的边界位于第一通孔H1的边界外侧，在显示面板30受到外界挤压或跌落冲击时，支撑结构10可以对显示面板30起到完全支撑的作用，避免了在支撑结构10的第二通孔H2的边缘与显示面板30造成应力集中而导致显示面板30破裂，从而提升了显示模组1的抗挤压和抗冲击的机械能力。
可以理解的是，支撑结构10的第二通孔H2的尺寸可以以与摄像头不形成干涉所需要的尺寸为准进行设置，在此基础上，显示面板30的第一通孔H1的尺寸需要比支撑结构10的第二通孔H2的尺寸大一些或者相等。
本公开实施例中的第一通孔H1的形状为圆形，但不限于此，第一通孔H1的形状还可以为矩形、椭圆形或其它不规则形状等。
本公开实施例中的第二通孔H2的形状为圆形，但不限于此，第二通孔H2的形状还可以为矩形、椭圆形或其它不规则形状等。
本公开实施例提供的显示模组1，第一通孔H1的边界位于第二通孔H2的边界外侧时，第一通孔H1和第二通孔H2可以为相同形状或者不同形状，只要保证第一通孔H1的边界位于第二通孔H2的边界外侧即可。
在一些实施例中，参考图5，显示面板30包括显示基板31和设置于显示基板31上的黑矩阵层32，黑矩阵层32位于显示区Q1，并在显示区Q1具有多个开口，多个开口内一一对应的设置多个色阻，多个色阻包括多种颜色的色阻，以使与色阻颜色相同的光线通过。黑矩阵层32位于任意相邻的色阻之间，用于防止显示基板31中的子像素之间出现色混淆，增加对比度。黑矩阵层32和上述多个色阻形成彩色滤光片，用于减少外界环境光在显示面板30内的反射，提高显示面板30的显示品质。该彩色滤光片可以设于显示面板30的封装层上，因此该彩色滤光片又称COE(colorfilm on encapsulation，彩色滤光片在封装层上)结构。
基于上述结构，在本实施例中，黑矩阵层32进一步延伸至孔边区Q2，以遮挡孔边区Q2，防止显示区Q1的子像素的光线经孔边区Q2射出而造成漏光。本实施例中，直接采用黑矩阵层32覆盖孔边区Q2来遮挡孔边区Q2的光线，相比在孔边区Q2单独设置用于遮光的膜层，由于不需要考虑遮光的膜层与显示面板的贴合精度，而在遮光的膜层预留额外的遮光面积，因此可以实现窄边框；并且节省了工艺步骤。
在另一些实施例中，参考图6，显示面板30包括显示基板31，和设置于显示基板31上的偏光片33，第一通孔H1还贯穿偏光片33。第一显示部L1包括显示区Q1和孔边区Q2，孔边区Q2位于显示区Q1和第一通孔H1之间且围绕第一通孔H1。
为了遮挡显示面板30在孔边区Q2的光线，显示面板30还包括第二遮光层50，设于偏光片33远离显示基板31的一侧，且覆盖孔边区Q2。偏光片33用于减少外界环境光在显示面板内的反射，提高显示面板30的显示品质。
在此基础上，当第一通孔H1的边界位于第二通孔H2的边界外侧时，外界环境的光从显示面板30的出光侧照射至通孔区Q3时，支撑结构10的第一支撑部M1相比显示面板30的第一显示部L1伸出的部分会反射外界环境的光，对于显示面板30包括显示基板31和设置于显示基板31上的黑矩阵层32时，孔边区Q2的黑矩阵层32会将一部分外界环境的光进行吸收不会反射出去，对于显示面板30包括显示基板31，和设置于显示基板31上的偏光片33，显示面板30还包括设于偏光片33远离显示基板31的一侧且覆盖孔边区Q2的第二遮光层50时，孔边区Q2的第二遮光层50会将一部分外界环境的光进行吸收不会反射出去，因此在显示模组1的出光侧会引入正面孔区目视色差问题，即孔边区Q2中有黑矩阵层32遮盖的部分和支撑结构10的第一支撑部M1相比显示面板30的第一显示部L1伸出的部分存在色差，或者，孔边区Q2中有第二遮光层50遮盖的部分和支撑结构10的第一支撑部M1相比显示面板30的第一显示部L1伸出的部分存在色差。
为解决上述问题，在一些实施例中，参考图7，在第一通孔H1处，第一支撑部M1的部分相比第一显示部L1伸出；显示模组1还包括第一遮光层40，设于第一显示部L1和第一支撑部M1之间，在向参考面的正投影中，第一遮光层40至少覆盖第一支撑部M1相比第一显示部L1伸出的部分。其中，参考面为显示面板30远离支撑结构10的表面所在的平面。这样设置，当外界环境的光从显示面板30的出光侧照射至通孔区Q3时，第一支撑部M1相比第一显示部L1伸出的部分不会反射外界环境的光或者只反射一小部分光，因此改善了显示模组1的出光侧正面孔边区Q2的目视色差问题。
在一些实施例中，黑矩阵层32和第一遮光层40的吸光系数相同。这样设置有利于改善在显示模组1的出光侧引入的正面孔区目视色差问题。示例性地，第一遮光层40的颜色可以与黑矩阵层32的颜色相同或相近。例如，第一遮光层40的材料可以与黑矩阵层32的材料相同，例如均为黑色油墨。
继续参考图7，显示模组1还包括：粘胶层20，设于第一显示部L1和第一支撑部M1之间，粘胶层20被配置为粘结支撑结构10与显示面板30。
示例性地，粘胶层20包括第一子胶层21、第二子胶层22以及位于第一子胶层21和第二子胶层22之间的基材层23；其中，基材层23包括聚酰亚胺(Polyimide，简称：PI)基材层或者聚对苯二甲酸乙二醇酯(Polyethylene terephthalate，简称：PET)基材层。
示例性地，粘胶层还可以为单层，单层粘胶层的材料包括光学胶(Optically Clear Adhesive，简称：OCA)。
粘胶层20具有贯穿粘胶层20的第三通孔H3，从而第一通孔H1、第三通孔H3和第二通孔H2形成相贯通的容纳空间。示例性地，第三通孔H3的边界与第一通孔H1的边界重合，以避免对摄像头造成干涉。
在一些实施例中，继续参考图7，在第三通孔H3的边界与第一通孔H1的边界重合的 情况下，第一遮光层40可以至少设于第一支撑部M1朝向第一显示部L1的表面。
示例性地，参考图7，第一遮光层40仅覆盖支撑结构10的第一支撑部M1相比显示面板30的第一显示部L1伸出的部分的表面，这样第一遮光层40和延伸至孔边区Q2的黑矩阵层32组合起来，共同遮挡孔边区Q2。
示例性地，参考图8，第一遮光层40覆盖支撑结构10的第一支撑部M1相比显示面板30的第一显示部L1伸出的部分的表面，并向远离第二通孔H2的方向延伸，也就是说，在向参考面的正投影中，第一遮光层40与黑矩阵层32中位于孔边区Q2的部分交叠，这样可以确保第一遮光层40与黑矩阵层32交接位置处不会漏光，保证孔边区Q2被完全遮挡。
示例性地，参考图9，第一遮光层40还覆盖第一通孔H1的侧壁和第三通孔H3的侧壁。在视线与参考面(参考面为显示面板30远离支撑结构10的表面所在的平面)的法线存在夹角的情况下，即侧视角的情况下，由于第一通孔H1的侧壁和第三通孔H3的侧壁被第一遮光层40覆盖，因此，显示模组在侧视角下的色差也可得到改善。
示例性地，参考图10，第一遮光层40还覆盖第二通孔H2的侧壁。在视线与参考面的法线存在夹角的情况下，由于第一通孔H1的侧壁、第二通孔H2和第三通孔H3的侧壁均被第一遮光层40覆盖，因此，显示模组在侧视角下的色差可得到进一步改善。
在第一遮光层40覆盖第一通孔H1、第二通孔H2和第三通孔H3的侧壁的情况下，第一遮光层40的形成步骤可以为：参考图11，在将支撑结构10设置在显示面板30的背光侧之后，采用喷涂工艺，在第二通孔H2的侧壁、支撑结构10靠近显示面板30的表面、第三通孔H3的侧壁以及第一通孔H1的侧壁形成第一遮光层40。
示例性地，采用喷涂装置P进行喷涂，喷涂的材料包括油墨。
可以理解的是，在第一遮光层40还覆盖第一通孔H1的侧壁和第三通孔H3的侧壁的情况下，也可采用上述方法形成第一遮光层40，不同的是，仅需通过调整喷涂的角度、遮挡第二通孔H2的侧壁等方式，避免在第二通孔H2的侧壁上喷涂油墨即可。
此外，继续参考图9和图10，在一些可能的设计中，第一遮光层40覆盖第一通孔H1的侧壁，且与黑矩阵层32连接。这样可以避免黑矩阵层32与第一遮光层40在第一通孔H1的侧壁处形成缝隙，防止显示基板31的光从缝隙处漏出。
在另一些实施例中，参考图12，在向参考面的正投影中，第三通孔H3的边界介于第一通孔H1的边界和第二通孔H2的边界之间，第一遮光层40至少设于第一支撑部M1朝向第一显示部L1的表面。
示例性地，第一遮光层40可以仅覆盖支撑结构10的第一支撑部M1相比显示面板30的第一显示部L1伸出的部分的表面。或者，继续参考图12，第一遮光层40覆盖第一支撑部M1相比第一显示部L1伸出的部分的表面，并向远离第二通孔H2的方向延伸，以使得在向参考面的正投影中，第一遮光层40与黑矩阵层32交叠。这样可以确保第一遮光层40与黑矩阵层32交接位置处不会漏光，保证孔边区Q2被完全遮挡。
示例性地，参考图13，第一遮光层40覆盖支撑结构10的第一支撑部M1相比显示面 板30的第一显示部L1伸出的部分的表面，还覆盖粘胶层20相比显示面板30的第一显示部L1伸出的部分远离支撑结构10的第一支撑部M1的表面。这样，可以避免侧视角的光线从黑矩阵层32与设于支撑结构10表面的第一遮光层40之间射出，从而避免漏光。
在另一些实施例中，在向参考面的正投影中，第三通孔H3的边界与第二通孔H2的边界重合，第一遮光层40设于粘胶层20靠近或远离支撑结构10的表面，或粘胶层20内部。
示例性地，参考图14，第一遮光层40设于粘胶层20靠近支撑结构10的表面。
示例性地，参考图15，第一遮光层40设于粘胶层20远离支撑结构10的表面。
示例性地，参考图16、图17和图18，第一遮光层40设于粘胶层20内部。
粘胶层20包括第一子胶层21、第二子胶层22以及位于第一子胶层21和第二子胶层22之间的基材层23。在第一遮光层40设于粘胶层20内部的情况下，第一遮光层40设于第一子胶层21和基材层23之间，和/或，第二子胶层22和基材层23之间。
例如，参考图16，第一遮光层40设于第一子胶层21和基材层23之间。
例如，参考图17，第一遮光层40设于第二子胶层22和基材层23之间。
例如，参考图18，第一子胶层21和基材层23之间，和第二子胶层22和基材层23之间均设有第一遮光层40。
此外，在一些可能的设计中，参考图19，粘胶层20中的基材层23包括遮光材料，作为第一遮光层40。也就是说，基材层23除了用作第一子胶层21和第二子胶层22的载体，还复用为第一遮光层40。这样可以避免额外增加一层结构，有利于减小显示模组的厚度。
在上述设计方式，可以在制备粘胶层20的过程中，将遮光材料添加在溶剂状态的基材层材料中，之后涂覆该溶剂并经过固化形成具有遮光作用的基材层。例如，所添加的遮光材料可以选用碳粉。
对于显示面板30包括显示基板31、设置于显示基板31上的偏光片33以及第二遮光层50时，为了解决在显示模组1的出光侧会引入正面孔区目视色差问题，在显示模组中设置第一遮光层，第一遮光层可能设置的情况，参照上面的描述，在此不再赘述。
在一些实施例中，第二遮光层50和第一遮光层40的吸光系数相同。这样设置有利于改善在显示模组1的出光侧引入的正面孔区目视色差问题。
示例性地，第一遮光层40的颜色可以与第二遮光层50的颜色相同或相近。例如，第一遮光层40的材料可以与第二遮光层50的材料相同，例如均为黑色油墨。
参考图20，本公开的实施例还提供一种显示装置1000，该显示装置1000包括显示模组1、摄像头4和盖板2。
其中，显示模组1中贯穿显示面板30的第一通孔H1的边界位于贯穿支撑结构10的第二通孔H2的边界外侧，或第一通孔H1的边界与第二通孔H2的边界重合。这样在显示装置1000受到外界挤压或跌落冲击时，支撑结构10可以对显示面板30起到完全支撑的作用，避免了在支撑结构10的第二通孔H2的边缘与显示面板30造成应力集中而导致显示面板30破裂，从而提升了显示装置1000的抗挤压和抗冲击的机械能力。
需要说明的是，显示模组1包括前任一实施例提供的显示模组，在此不再赘述。
摄像头4设于第一通孔H1和第二通孔H2内。
盖板2设于显示模组1的出光侧，且覆盖摄像头4。盖板2为柔性盖板，盖板2的材料和作用可参考前面的相应的描述，此处不再赘述。
在一些实施例中，显示装置1000还包括：光学胶层3，设于盖板2和显示模组1之间，光学胶层3被配置为粘结显示模组1与盖板2。
示例性地，光学胶层3为无色透明、高透过率、胶结强度良好的光学胶(Optically Clear Adhesive，简称：OCA)，光学胶的粘结强度较高，且具有较高的透明度，不会影响显示模组的显示效果。
光学胶层3具有贯穿光学胶层3的第四通孔H4，第四通孔H4与第一通孔H1相贯通，这样设置不仅可以将盖板2和显示模组1之间充分的粘结，还可以避免光学胶层3对摄像头4形成遮挡，提高摄像头的成像质量。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
