具体实施方式
下面将结合附图，对本公开一些实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开所提供的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本公开保护的范围。
除非上下文另有要求，否则，在整个说明书和权利要求书中，术语“包括(comprise)”及其其他形式例如第三人称单数形式“包括(comprises)”和现在分词形式“包括(comprising)”被解释为开放、包含的意思，即为“包含，但不限于”。在说明书的描述中，术语“一个实施例(one embodiment)”、“一些实施例(some embodiments)”、“示例性实施例(exemplary embodiments)”、“示例(example)”、“特定示例(specific example)”或“一些示例(some examples)”等旨在表明与该实施例或示例相关的特定特征、结构、材料或特性包括在本公开的至少一个实施例或示例中。上述术语的示意性表示不一定是指同一实施例或示例。此外，所述的特定特征、结构、材料或特点可以以任何适当方式包括在任何一个或多个实施例或示例中。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本公开实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
如本文所使用的那样，“约”、“大致”或“近似”包括所阐述的值以及处于特定值的可接受偏差范围内的平均值，其中所述可接受偏差范围如由本领域普通技术人员考虑到正在讨论的测量以及与特定量的测量相关的误差(即，测量系统的局限性)所确定。
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，放大了层和区域的厚度。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。
如图1所示，本公开的一些实施例提供一种显示装置100，该显示装置100可以为电视、手机、电脑、笔记本电脑、平板电脑、个人数字助理(英文：Personal Digital Assistant，简称PDA)、车载电脑等。
如图1所示，显示装置100包括显示面板1、框架2、盖板3以及电路板4等其它电子配件。
其中，框架2的纵截面呈U型，盖板3设置于框架2的开口侧，显示面板1、电路板4以及其它电子配件均设置于框架2内，电路板4设置于显示面板1的远离盖板3的一侧。
在一些实施例中，如图2所示，显示装置100还包括位于盖板3与显示面板1之间的圆偏光片5。圆偏光片5被配置为减少外界光线被显示面板1中的金属结构反射后的反射光线。其中，参见图3，圆偏光片5可以通过粘接层6与盖板3贴附在一起；例如，圆偏光片5通过光学胶与盖板3贴附在一起。
在一些实施例中，如图2所示，显示面板1具有显示区A和位于显示区A1至少一侧的周边区B，附图2以周边区B包围显示区A为例进行示意。
其中，显示区A为显示图像的区域；周边区B为不显示图像的区域，周边区B被配置为设置显示驱动电路，例如，栅极驱动电路和源极驱动电路。
在一些实施例中，如图2和图3所示，显示区A包括功能器件设置区A2和围绕功能器件设置区的主显示区A1，主显示区A1被配置为设置多个亚像素P；功能器件设置区A2中设置有安装孔H，功能器件设置区A2包括围绕安装孔H的预留区域A21。
其中，至少一种功能器件可以设置在安装孔H内；功能器件可以为摄像头、红外传感器、近距离传感器、眼球追踪模组和人脸识别模组等等。示例性的，如图2所示，功能器件设置区A2为摄像头设置区，功能器件为摄像头。
参阅图4A和图4B，显示面板1包括显示用基板11和用于封装显示用基板11的封装层12。
此处，封装层12可以为封装薄膜，也可以为封装基板。
在一些实施例中，如图4B所示，显示用基板11的每个亚像素P(参阅图2)均包括设置于衬底111上的发光器件和像素驱动电路，像素驱动电路包括多个薄膜晶体管112。薄膜晶体管112包括有源层、源极、漏极、栅极及栅绝缘层，源极和漏极分别与有源层接触。沿垂直于衬底111且远离衬底111的方向，发光器件包括第一电极113、发光功能层114和第二电极115。
此处，第一电极113为发光器件的阳极，第二电极115为发光器件的阴极；或者，第一电极113为发光器件的阴极，第二电极115为发光器件的阳极。以上情况均可，具体根据实际情况选择设置。
示例性的，如图4B所示，第一电极113为发光器件的阳极，第二电极115为发光器件的阴极。第一电极113和多个薄膜晶体管112中作为驱动晶体管的薄膜晶体管112的源极或漏极电连接。
显示用基板11还包括像素界定层116，像素界定层116包括多个开口区，一个发光器件312设置于一个开口区中。
在一些实施例中，发光功能层114仅包括发光层。在另一些实施例中，发光功能层114除包括发光层外，还包括电子传输层(election transporting layer，简称ETL)、电子注入层(election injection layer，简称EIL)、空穴传输层(hole transporting layer，简称HTL)和空穴注入层(hole injection layer，简称HIL)中的至少一个。
如图4B所示，显示用基板11还包括设置于薄膜晶体管112和第一电极113之间的第一平坦层117。
如图4B所示，显示用基板11还包括设置于封装层12和第二电极115之间的第二平坦层118。
在一种相关技术中，如图3所示，盖板3靠近显示面板1的表面设有遮光图案7＇，遮光图案7＇的内边界在显示面板1上的正投影位于预留区域A21的内边界的内侧，以防止安装孔H处漏光；遮光图案7＇的外边界在显示面板1上的正投影位于预留区域A21的外边界外侧或与预留区域A21的外边界近似重合，以遮蔽安装孔H的侧壁毛刺和安装孔H的边缘的裂缝等切割不良。
但是，在相关技术中的显示装置100的制作过程中，盖板2与圆偏光片5需要对位一次，对盖板3上设置的遮光图案7＇的工艺精度的要求较高。在这种情况下，为了保证遮光图案7＇能够遮蔽安装孔H的侧壁毛刺和安装孔H的周向的预留区域A21的裂缝等切割不良，以及防止安装孔H处漏光，无法将遮光图案7＇的宽度设计的很小(遮光图案7＇的宽度极限能到0.5mm)， 这样造成显示区域减小，屏占比降低。
本公开的一些实施例提供了一种显示模组1000，参阅图4B、图5B和图6B，具有功能器件设置区A2，及围绕功能器件设置区A2的主显示区A1；功能器件设置区A2中设置有安装孔H，功能器件设置区A2包括围绕安装孔H的预留区域A21；安装孔H的侧壁呈阶梯状或凹凸结构。
如图4B和图4C所示，显示模组1000包括显示面板1、第一遮光图案7、粘接层6和第二遮光图案8，第一遮光图案7设置于显示面板1的出光侧，第一遮光图案7在显示面板1上的正投影与显示面板1的预留区域A21大致重合，以遮蔽安装孔H周向的预留区域A21的裂缝等切割不良；粘接层6设置于第一遮光图案7远离显示面板1的一侧，安装孔H贯穿显示面板1、第一遮光图案7和粘接层6；第二遮光图案8至少覆盖安装孔H的侧壁，以遮蔽安装孔H的侧壁毛刺以及有效的防止安装孔H处漏光。
由上述可知，本公开的一些实施例提供的显示模组1000中，第一遮光图案7设置于显示面板1的出光侧，粘接层6设置于第一遮光图案7远离显示面板1的一侧，这样的话，第一遮光图案7可以采用沉积工艺(例如，蒸镀)或光刻工艺直接形成在显示面板1上的预留区域A21，相较于将第一遮光图案7设置于盖板3，可以降低工艺难度。基于此，相较于相关技术，本公开的一些实施例提供的显示模组1000中的第一遮光图案7的宽度可以设计的更小(第一遮光图案7的宽度的近似0.3mm)，从而增大显示区域。
此外，安装孔H的侧壁呈阶梯状或凹凸结构，可以增大第二遮光图案8与安装孔H的接触面积，加强第二遮光图案8与安装孔H的贴覆力，降低第二遮光图案8脱离的风险。
其中，第一遮光图案7和第二遮光图案8的材料为黑色油墨或黑色热熔胶。当然，第一遮光图案7和第二遮光图案8的材料选用其他黑色遮光材料也是可行的，本公开实施例不限于此。
在一些实施例中，如图4C、图5C和图6C所示，第一遮光图案7与第二遮光图案8连接，以保证预留区域A21上的第一遮光图案7与安装孔H的侧壁上的第二遮光图案8之间不存在漏光区域，有效防止安装孔H处漏光。
为了防止外界环境光对所要显示的图像造成干扰，在一些实施例中，上述显示模组1000还包括圆偏光片5，圆偏光片5设置于显示面板1与粘接层6之间，且第一遮光图案7位于圆偏光片5靠近显示面板1的一侧，安装孔H贯穿圆偏光片5。在这种情况下，圆偏光片5能够有效的防止外界环境 光对所要显示的图像造成干扰。
在另一些实施例中，参阅图7，上述显示模组1000包括黑矩阵图案BM(Black Matrix，简称BM)，黑矩阵BM设置于显示面板1与粘接层6之间。黑矩阵图案BM被配置为，将从不同亚像素P发出的光间隔开，并减少外界环境光进入显示面板1内部后产生反射光线的作用，即降低外界环境光对所要显示的图像造成干扰。此时，第一遮光图案7可以与黑矩阵图案BM同层同材料设置。
在一些实施例中，如图4C、图5C和图6C所示，安装孔H包括多个子孔，多个子孔沿显示面板1的厚度方向排列，且至少有两个相邻的子孔的侧壁不平齐。
需要说明的是，每个子孔的侧壁的表面平整，每个子孔的侧壁可以大致平行于显示面板1的厚度方向(参见图4B、图5B和图6B)，或每个子孔的侧壁可以与显示面板1的厚度方向呈一定夹角(参见图4C、图5C和图6C)。其中，在每个子孔的侧壁与显示面板1的厚度方向呈一定夹角的情况下，每个子孔的最大孔径与最小孔径的差值为30μm～100μm。
示例性地，如图4C、图5C和图6C所示，安装孔H包括第一子孔H1、第二子孔H2和第三子孔H3，沿显示面板1的厚度方向且由显示面板1指向粘接层6的方向，第一子孔H1、第二子孔H2和第三子孔H3依次排列。
相应的，如图4C、图5C和图6C所示，第二遮光图案8包括覆盖第一子孔H1的侧壁的第一子图案81，覆盖第二子孔H2的侧壁的第二子图案82，和覆盖第三子孔H3的侧壁的第三子图案83。
在一些实施例中，如图4C所示，第一子孔H1靠近第二子孔H2的一端的孔径小于第二子孔H2靠近第一子孔H1的一端的孔径，第一子孔H1的侧壁与第二子孔H2的侧壁形成台阶结构；第二子孔H2靠近第三子孔H3内的一端的孔径小于第三子孔H3靠近第二子孔H2的一端的孔径，第二子孔H2的侧壁的与第三子孔H3的侧壁形成台阶结构。示例性地，第一子孔H1靠近第二子孔H2的一端的孔径比第二子孔H2靠近第一子孔H1的一端的孔径小50μm～150μm，第二子孔H2靠近第三子孔H3内的一端的孔径比第三子孔H3靠近第二子孔H2的一端的孔径小50μm～150μm。
相应的，如图4C所示，第一子图案81靠近第一子孔H1的侧壁的边界相对于第二子图案82靠近第二子孔H2的侧壁的边界靠近安装孔H的轴线；第二子图案82靠近第二子孔H2的侧壁的边界相对于第三子图案83靠近第三子孔H3的侧壁的边界靠近安装孔H的轴线。
在另一些实施例中，如图5C所示，第一子孔H1靠近第二子孔H2的一端的孔径小于第二子孔H2靠近第一子孔H1的一端的孔径，第一子孔H1的侧壁与第二子孔H2的侧壁形成台阶结构；第二子孔H2靠近第三子孔H3的一端的孔径等于第三子孔H3靠近第二子孔H2的一端的孔径，第二子孔H2与第三子孔H3的侧壁平齐。示例性地，第一子孔H1靠近第二子孔H2的一端的孔径比第二子孔H2靠近第一子孔H1的一端的孔径小50μm～150μm。
相应的，如图5C所示，第一子图案81靠近第一子孔H1的侧壁的边界相对于第二子图案82靠近第二子孔H2的侧壁的边界靠近安装孔H的轴线；第二子图案82靠近第二子孔H2的侧壁的边界与第三子图案83靠近第三子孔H3的侧壁的边界平齐。
在又一些实施例中，如图6C所示，第一子孔H1靠近第二子孔H2的一端的孔径小于第二子孔H2靠近第一子孔H1的一端的孔径，第一子孔H1的侧壁与第二子孔H2的侧壁形成台阶结构；第二子孔H2靠近第三子孔H3的一端的孔径大于第三子孔H3靠近第二子孔H2的一端的孔径，第三子孔H3的侧壁相对于与第二子孔H2的侧壁凸起。示例性地，第一子孔H1靠近第二子孔H2的一端的孔径比第二子孔H2靠近第一子孔H1的一端的孔径小50μm～200μm，第二子孔H2靠近第三子孔H3内的一端的孔径比第三子孔H3靠近第二子孔H2的一端的孔径大50μm～200μm。
相应的，如图6C所示，第一子图案81靠近第一子孔H1的侧壁的边界相对于第二子图案82靠近第二子孔H2的侧壁的边界靠近安装孔H的轴线；第二子图案82靠近第二子孔H2的侧壁的边界相对于第三子图案83的靠近第三子孔H3的侧壁的边界远离安装孔H的轴线。
其中，显示面板1中设有多层无机膜，无机膜相较于有机膜，更加脆弱，针对显示面板1开孔的过程中，无机膜对应的孔的边缘易产生裂痕。基于此，在一些实施例中，如图4C、5C和图6C所示，第一子孔H1贯穿显示面板1和第一遮光图案7，第二子孔H2贯穿圆偏光片5，第三子孔H3贯穿粘接层6。
在这种情况下，显示面板1只需要开孔一次，且无需对显示面板1对应的子孔的侧壁在进行切割处理，降低显示面板1对应的子孔的边缘产生裂痕的风险，显示面板1的预留区域A21的宽度可以设计的更窄。
需要说明的是，在本公开实施例中，第一子孔H1、第二子孔H2和第三子孔H3分别贯穿的膜层不限于此。
在一些实施例中，如图4B、图5B和图6B所示，显示模组1000还包括第一保护层9，第一保护层9设置于粘接层6远离显示面板1远离的一侧，第一保护层9对粘接层6远离显示面板1远离的一侧的表面起到保护的作用。
其中，为制备显示装置100，在后续的工艺过程中，上述显示模组1000的第一保护层9需要剥离下来，以将盖板3贴附在粘接层上。基于此，第一保护层9可以为离型膜，易于第一保护层9的剥离。
在此基础上，如图4C、图5C和图6C所示，安装孔H还包括贯穿第一保护层9的第四子孔H4，第四子孔H4靠近第三子孔H3的一端的孔径大于第三子孔H3靠近第四子孔H4的一端的孔径，第四子孔H4的侧壁与第三子孔H3的侧壁形成台阶结构。示例性地，第四子孔H4靠近第三子孔H3的一端的孔径比第三子孔H3靠近第四子孔H4的一端的孔径大100μm～300μm。
相应的，如图4C、图5C和图6C所示，第二遮光图案8还包括第四子图案84，第四子图案84覆盖粘接层6远离显示面板1的表面中超出第一保护层9的部分。例如，第四子图案84在显示面板1上的正投影，位于显示面板1的预留区域A21之内；又例如，第四子图案84在显示面板1上的正投影与显示面板的预留区域A21大致重合。
在这种情况下，由于第四子图案84还与粘接层6大面积贴合，因此，在剥离第一保护层9的过程中，可以降低第一保护层9与第四子图案84接触处产生拉胶的风险，便于撕离。
此外，第四子图案84还能够遮挡第一遮挡图案7远离显示面板1的一侧的预留区域A21对应的子孔的边缘的裂痕，并进一步地降低漏光的风险。
其中，在上述第四子图案84制备的过程中，第四子图案84与第二遮光图案8中覆盖安装孔H侧壁的部分一体设置，这样可以简化工艺，降低制作成本。
在一些实施例中，如图4B、图5B和图6B所示，显示模组1000还包括第二保护层10，第二保护层10设置于显示面板1远离粘接层6的一侧，以对显示面板1起到支撑和保护的作用。
在此基础上，如图4C、图5C和图6C所示，安装孔H还包括贯穿第二保护层10的第五子孔H5，第五子孔H5靠近第一子孔H1的一端的孔径等于第一子孔H1靠近第五子孔H5的一端的孔径，第五子孔H5的侧壁与第一子孔H1的侧壁平齐。
相应的，如图4C、图5C和图6C所示，第二遮光图案还包括覆盖第五子孔的侧壁的第五子图案。
在一些实施例中，如图4C、图5C和图6C所示，第二遮光图案8靠近安装孔H的轴线的表面平整，以减少对第二遮光图案8对应显示面板1的显示侧的一端的开口接收的外界光产生不良的干扰，保证更多的外界光可以通过安装孔H进入功能器件。
此外，第二遮光图案8靠近安装孔H轴线的表面大致平行于安装孔H的轴线。也就是说，第二遮光图案8的内径近似相等，第二遮光图案8对应显示面板1的显示侧的一端的开口接收的外界光，大部分均可以通过安装孔H进入功能器件，这样可以在功能器件设置区A2占用较小的显示区域的情况下，保证充足的外界光可以通过安装孔H进入功能器件。
本公开的一些实施例还提供了一种显示装置100的制作方法，如图8所示，包括S100～S600。
S100，提供显示面板1，显示面板1包括功能器件设置区A2，及围绕功能器件设置区A2的主显示区A1。
S200，在显示面板1的出光侧制作第一遮光图案7，第一遮光图案7在显示面板1上的正投影与显示面板1的功能器件设置区A2大致重合。
示例性地，采用涂布的方法在显示面板1的出光侧形成第一遮光膜，然后依次通过曝光、显影、刻蚀获得第一遮光图案7，第一遮光图案7在显示面板1上的正投影与显示面板1的功能器件设置区A2大致重合。
S300，在形成有第一遮光图案7的显示面板1的出光侧依次设置圆偏光片5、粘接层6和第一保护层9。
示例性地，圆偏光片5可以通过粘接的方法在第一遮光图案7远离显示面板1的一侧，与显示面板1及第一遮光图案7粘接；粘接层6和第一保护层9为一体来料，直接与圆偏光片5远离显示面板1的表面粘接。
S400，在显示面板1的功能器件设置区A2开孔，形成初始孔，初始孔贯穿显示面板1、第一遮光图案7、圆偏光片5、粘接层6和第一保护层9。
示例性地，在第一保护层9远离显示面板1的一侧，将一束激光的焦点汇聚在显示面板1远离粘接层6的一侧，对第一保护层9、粘接层6、圆偏光片5、第一遮光图案7和显示面板1进行切割，形成初始孔。
例如，利用脉冲式飞秒激光器发射激光，激光的频率为500KHZ～800KHZ，对应的切割速度为300mm/s～1500mm/s，切割30次～100次，形成初始孔。

其中，显示模组1000包括显示面板1、第一遮光图案7、粘接层6和第二遮光图案8，第一遮光图案7设置于显示面板1的出光侧，第一遮光图案7在显示面板1上的正投影与显示面板1的预留区域A21大致重合；粘接层6设置于第一遮光图案7远离显示面板1的一侧，安装孔H贯穿显示面板1、第一遮光图案7和粘接层6；第二遮光图案8至少覆盖安装孔H的侧壁；盖板3设置于粘接层6远离显示面板1的一侧。
在一些实施例中，参阅图4C、图5C和图6C，安装孔H包括多个子孔，多个子孔沿显示面板1的厚度方向排列，且至少有两个相邻的子孔的侧壁不平齐。
需要说明的是，每个子孔的侧壁的表面平整，每个子孔的侧壁可以大致平行于显示面板1的厚度方向(参见图4B、图5B和图6B)，或每个子孔 的侧壁可以与显示面板1的厚度方向呈一定夹角(参见图4C、图5C和图6C)。其中，在每个子孔的侧壁与显示面板1的厚度方向呈一定夹角的情况下，每个子孔的最大孔径与最小孔径的差值为30μm～100μm。
示例性地，如图4C、图5C和图6C所示，安装孔H包括第一子孔H1、第二子孔H2和第三子孔H3，沿显示面板1的厚度方向且由显示面板1指向粘接层6的方向，第一子孔H1、第二子孔H2和第三子孔H3依次排列。

相应的，如图4A和图4C所示，第一子图案81靠近第一子孔H1的侧壁的边界相对于第二子图案82靠近第二子孔H2的侧壁的边界靠近安装孔H的轴线；第二子图案82靠近第二子孔H2的侧壁的边界相对于第三子图案83靠近第三子孔H3的侧壁的边界靠近安装孔H的轴线。
在另一些实施例中，如图5A和图5C所示，第一子孔H1靠近第二子孔H2的一端的孔径小于第二子孔H2靠近第一子孔H1的一端的孔径，第一子孔H1的侧壁与第二子孔H2的侧壁形成台阶结构；第二子孔H2靠近第三子孔H3的一端的孔径等于第三子孔H3靠近第二子孔H2的一端的孔径，第二子孔H2与第三子孔H3的侧壁平齐。示例性地，第一子孔H1靠近第二子孔H2的一端的孔径比第二子孔H2靠近第一子孔H1的一端的孔径小50μm～150μm。
相应的，如图5A和图5C所示，第一子图案81靠近第一子孔H1的侧壁的边界相对于第二子图案82靠近第二子孔H2的侧壁的边界靠近安装孔H的轴线；第二子图案82靠近第二子孔H2的侧壁的边界与第三子图案83靠近第三子孔H3的侧壁的边界平齐。
在又一些实施例中，如图6A和图6C所示，第一子孔H1靠近第二子孔 H2的一端的孔径小于第二子孔H2靠近第一子孔H1的一端的孔径，第一子孔H1的侧壁与第二子孔H2的侧壁形成台阶结构；第二子孔H2靠近第三子孔H3的一端的孔径大于第三子孔H3靠近第二子孔H2的一端的孔径，第三子孔H3的侧壁相对于与第二子孔H2的侧壁凸起。示例性地，第一子孔H1靠近第二子孔H2的一端的孔径比第二子孔H2靠近第一子孔H1的一端的孔径小50μm～200μm，第二子孔H2靠近第三子孔H3内的一端的孔径比第三子孔H3靠近第二子孔H2的一端的孔径大50μm～200μm。
相应的，如图图6A和图6C所示，第一子图案81靠近第一子孔H1的侧壁的边界相对于第二子图案82靠近第二子孔H2的侧壁的边界靠近安装孔H的轴线；第二子图案82靠近第二子孔H2的侧壁的边界相对于第三子图案83的靠近第三子孔H3的侧壁的边界远离安装孔H的轴线。
在一些实施例中，显示装置100的显示模组1000还包括圆偏光片5，圆偏光片5设置于显示面板1与粘接层6之间，且第一遮光图案7位于圆偏光片5靠近显示面板1的一侧，安装孔H贯穿圆偏光片5。
其中，显示面板1中设有多层无机膜，无机膜相较于有机膜，更加脆弱，针对显示面板1开孔的过程中，无机膜对应的孔的边缘易产生裂痕。基于此，在一些实施例中，如图所示，第一子孔H1贯穿显示面板1和第一遮光图案7，第二子孔H2贯穿圆偏光片5，第三子孔H3贯穿粘接层6。
在这种情况下，显示面板1只需要开孔一次，且无需对显示面板1对应的子孔的侧壁在进行切割处理，降低显示面板1对应的子孔的边缘产生裂痕的风险，显示面板1的预留区域A21的宽度可以设计的更窄。
需要说明的是，在本公开实施例中，第一子孔H1、第二子孔H2和第三子孔H3分别贯穿的膜层不限于此。
在一些实施例中，如图4A、图5A和图6A所示，第二遮光图案8包括第四子图案84(参见图4C、图5C和图6C)，第四子图案84覆盖粘接层6远离显示面板1的表面中位于安装孔H周围的部分；盖板3靠近显示面板1的一面与第四子图案84的表面接触。
此处，第四子图案84在显示面板1上的正投影，位于显示面板1的预留区域A21之内；或，第四子图案84在显示面板1上的正投影与显示面板的预留区域A21大致重合。
在这种情况下，由于第四子图案84还与粘接层6大面积贴合，在显示装置100的制作过程中，在粘接层6上方的第一保护层9剥离的过程中，可以降低第一保护层9与第四子图案84接触处产生拉胶的风险，便于撕离。
此外，第四子图案84还能够遮挡第一遮挡图案7远离显示面板1的一侧的预留区域A21对应的子孔的边缘的裂痕，并进一步地降低漏光的风险。
其中，在上述第四子图案84制备的过程中，第四子图案84与第二遮光图案8中覆盖安装孔H侧壁的部分一体设置，这样可以简化工艺，降低制作成本。
在一些实施例中，如图4A、图5A和图6A所示，显示装置100的显示模组1000还包括第二保护层10，第二保护层10设置于显示面板1远离粘接层6的一侧，安装孔H贯穿第二保护层10。
在此基础上，参阅图4C、图5C和图6C，安装孔H还包括贯穿第二保护层10的第五子孔H5，第五子孔H5靠近第一子孔H1的一端的孔径等于第一子孔H1靠近第五子孔H5的一端的孔径，第五子孔H5的侧壁与第一子孔H1的侧壁平齐。
相应的，参阅图4C、图5C和图6C，第二遮光图案还包括覆盖第五子孔的侧壁的第五子图案。
在一些实施例中，如图4A、图5A和图6A所示，第二遮光图案8靠近安装孔H的轴线的表面平整，以减少对第二遮光图案8对应显示面板1的显示侧的一端的开口接收的外界光产生不良的干扰，保证更多的外界光可以通过安装孔H进入功能器件。
此外，第二遮光图案8靠近安装孔H轴线的表面大致平行于安装孔H的轴线。也就是说，第二遮光图案8的内径近似相等，第二遮光图案8对应显示面板1的显示侧的一端的开口接收的外界光，大部分均可以通过安装孔H进入功能器件，这样可以在功能器件设置区A2占用较小的显示区域的情况下，保证充足的外界光可以通过安装孔H进入功能器件。
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。
