背景技术
随着电子设备的快速发展，用户对屏占比的要求越来越高，使得电子设备的全面屏显示受到越来越多的关注。而由于需要集成如前置摄像头、听筒以及红外感应元件等，电子设备并不能在整个屏幕的各个区域均进行显示，无法实现真正意义上的全面屏。
发明内容
有鉴于此，本申请提供一种阵列基板、显示面板和显示装置。
根据本申请的实施例，提供一种阵列基板，其特征在于，包括：
衬底；
第一电极层，所述第一电极层形成于所述衬底上；
发光层，所述发光层形成于所述第一电极层上，包括第一发光区和第二发光区，所述第一发光区包括多个第一发光块，所述第二发光区包括多个第二发光块，所述多个第一发光块和所述多个第二发光块在同一个工艺中形成；和
第二电极层，所述第二电极层形成于所述发光层上；
其中，所述第一电极层包括对应所述第一发光区设置的多个第一电极，每一所述第一电极上对应多个所述第一发光块，且同一所述第一电极上的第一发光块的颜色相同，所述第一发光区为透明区，所述第二发光区为非透明区。同一第一电极对应的第一发光块颜色一致能够降低蒸镀难度，降低混色风险；第一发光区为透明区能够允许光线透过，从而使得配置有该阵列基板电子设备所包括的感光器件可以放置于该第一发光区下方，从而在能够采集或者发射光线的同时避免占用电子设备的显示区域，有利于提高屏占比。
可选的，至少部分所述第一发光区被所述第二发光区包围。
可选的，所述第一电极为条状电极，多个所述第一电极排列成一行多列、一列多行、两列多行、两行多列或多行多列。第一电极层上的第一电极采用规律性排布，能够降低加工难度，并且第二电极层采用面电极结构，进一步能够简化工艺步骤，降低生产成本。

可选的，每一所述第一电极上沿第一方向对应多列所述第一发光块，对应同一所述第一电极上沿第二方向相邻的两个所述第一发光块对齐设置或者错位设置，所述第二方向与所述第一方向垂直。基于此，可以在第一发光区的像素密度不变的情况下，可以在降低掩膜形变量的同时，减少第一电极的数量，降低加工难度。其中对齐设置可以降低对掩膜的加工要求；错位设置能够提高第一发光块排布的均匀性，提升显示效果。

可选的，所述第一电极在列方向上的两条边均为波浪形，且两条波浪形的边的波峰相对设置，波谷相对设置；和/或
所述第一发光块在所述第一电极的列方向上的两条边均为波浪形，且两条波浪形的边的波峰相对设置、波谷相对设置。因此在第一电极的不同宽度位置以及相邻第一电极的不同间距之间，产生的衍射条纹的位置不同，不同位置处的衍生效应相互抵消，从而可以有效减弱衍射效应。
可选的，每一所述第一电极在所述衬底上的投影的形状包括至少一个第一图形单元；每一所述第一发光块在所述衬底上的投影的形状包括至少一个第二图形单元；所述第一图形单元和/或所述第二图形单元包括圆形、椭圆形、哑铃形、葫芦形或矩形。

可选的，所述像素限定层还包括对应于所述第二发光区的多个第二像素限定孔，所述第二像素限定孔的尺寸等于或小于所述第一像素限定孔的尺寸。第一像素限定孔和第二像素限定孔的尺寸相等，可以降低对掩膜的加工难度；第一像素限定孔的尺寸可以大于第二像素限定孔的尺寸，从而在相邻第一像素限定孔之间间距等于相邻第二像素限定孔之间间距时，减小第一像素限定孔的分布密度，减少第一像素限定孔之间的间隙数量，降低光线的衍射概率。
可选的，多个所述第一发光块和多个所述第二发光块均排布成多列，且一一对应；同一列中所述第一发光块颜色与第二发光块中靠近所述第一发光区设置的第一个第二发光块颜色一致。。以降低对第一发光区的工艺要求，使得第一发光区在同一列方向的混色风险较小。可选的，多个所述第一发光块和多个所述第二发光块均排布成多列，同一列的至少一个所述第一发光块与该列所述第二发光块中靠近所述第一发光区设置的至少一个所述第二发光块组成一个像素重复单元。基于此，可以在第一发光区和第二发光区的交界处进行显示过渡，提升显示效果。
可选的，所述第一电极层和/或所述第二电极层为透明材料制成；所述透明材质的透光率大于或等于90％。
根据本申请实施例的第二方面，提供一种显示面板，包括：
如上述任一项实施例所述的阵列基板；
封装层，所述封装层封装于所述阵列基板上远离所述衬底的一侧；所述封装层包括偏光片，所述偏光片覆盖所述第二发光区，未覆盖所述第一发光区；和
芯片组件，控制所述第一发光块和所述第二发光块的显示状态。通过芯片组件调节第一发光区和第二发光区交界处的显示颜色，可以提升交界处的显示效果，降低视觉差异。
根据本申请实施例的第三方面，提供一种显示装置，包括：
设备本体，具有器件区；和
如上述任一项实施例所述的显示面板，所述显示面板覆盖在所述设备本体上；
其中，所述器件区位于所述第一发光区的下方，且所述器件区包括透过所述第一发光区发射或者采集光线的感光器件。感光器件设置于该第一发光区的下方，以保证感光器件能够正常工作，并且不占用显示区域，从而提升屏占比。
由上述实施例可知，本申请中多个第一发光块和第二发光块采用一张掩膜进行蒸镀，从而减少掩膜的数量，降低生产成本。由于可以在同一第一电极上形成多个第一发光块，在掩膜上对应于第一发光区上同一电极的区域可以形成多个孔，从而相较于在掩膜上开设一个大孔，能够提高掩膜的强度，缓冲应力，减少掩膜的形变，有效降低相邻第一发光块之间混色的风险。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。
应当理解，尽管在本申请可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本申请范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。
电子设备如手机、平板电脑等，由于需要集成诸如前置摄像头、听筒以及红外感应元件等，故而可通过在显示面板上开槽(Notch)，在开槽区域设置摄像头、听筒以及红外感应元件等，但开槽区域并不用来显示画面，如采用刘海屏等，或者采用在屏幕上开孔的方式。对于实现摄像功能的电子设备来说，外界光线可通过屏幕上的开孔处进入位于屏幕下方的感光器件。但是这些电子设备并不能在整个屏幕的各个区域均进行显示，如在摄像头区域不能显示画面，因而均不是真正意义上的全面屏。
基于当前电子设备的发展趋势，如何在保证电子设备前置拍摄功能的同时，将电子设备所配置的显示面板屏占比提高至接近100％，已经成为本领域内需要解决的问题。

在一实施例中，发光层3可以包括第一发光区31和第二发光区32。如图1所示，至少部分第一发光区31可以被第二发光区32包围。例如，第一发光区31可以全部被第二发光区32包围，或者第一发光区31的一侧边缘可以与第二发光区32的相对侧边缘接触。在一实施例中，如图1所示，第一发光区31可以为弧形；或者，第一发光区31可以为圆形、矩形、椭圆形或不规则形状等。
在一实施例中，如图2所示，该阵列基板100可以包括衬底1、第一电极层2、发光层3和第二电极层4。其中，衬底1可以包括基板、无机层和有机层等层结构。该基板可以包括柔性基板或者刚性基板，其中柔性基板可以采用柔性材料制成，该柔性材料可以为聚酰亚胺(Polyimide，简称PI)、聚碳酸酯(Polycarbonate，简称PC，也称PC塑料)、聚对苯二甲酸类(Polyethylene terephthalate，简称PET)等；刚性基板可以采用有机玻璃制成。第一电极层2形成在衬底1上，发光层3形成于第一电极层2上，第二电极层4形成于发光层3上。第一发光区31为透明区，第二发光区32为非透明区。配置有该阵列基板100的电子设备所包括的感光器件可以对应于第一发光区31设置。外部光线可以透过第一发光区31后被感光器件采集，内部光线可以透过第一发光区31而射出。基于此，可以在保证感光器件正常工作的同时，与感光器件对应的屏幕能够正常显示，从而不影响电子设备的屏占比。其中，当感光器件处于关闭状态时，感光器件对应的第一发光区31区域可以用于显示图像，并且第一发光区31示出的图像与第二发光区32示出的图像之间可以吻合，以保证图像显示的完整性，提升显示效果。在一实施例中，感光器件对应的第一发光区31也可以是静态显示。
在一实施例中，第一发光区31可以包括多个第一发光块311，第二发光区32可以包括多个第二发光块321。其中，第一发光块311和第二发光块321可以在同一个工艺中形成，以减少掩膜的数量，降低生产成本。
在一实施例中，第一电极层2还可以包括多个对应第一发光区31设置的第一电极，第一电极上可以对应多个第一发光块311，并且，同一第一电极对应的第一发光块311的颜色相同。
图3至图6是本申请根据不同示例性实施例示出的阵列基板的结构示意图。在一实施例中，如图3所示，第一电极层2可以包括第一电极21、22和23，第一电极21、第一电极22和第一电极23上分别对应两个第一发光块311。第一电极21上对应的第一发 光块311均为红色色块，第一电极22上对应的第一发光块311均为绿色色块，第一电极23上对应的第一发光块311均为蓝色色块。在一些实施例中，每个第一电极上还可以包括三个或者三个以上的第一发光块311，且不同第一电极所包括的第一发光块311的数量可以相同也可以不同，本申请并不限制。
其中，多个第一发光块311可以采用一张掩膜进行蒸镀，由于可以在同一第一电极上形成多个第一发光块311，相应的可以在一张掩膜上对应第一发光区31的区域形成多个孔，相较于在掩膜上开设一个大孔，能够提高掩膜的强度，减少掩膜的形变，有效降低相邻第一发光块311之间混色的概率。
在一实施例中，该第一电极可以为条状电极，如图3所示，多个第一电极可以排列成多行多列结构；或者，如图4所示，多个第一电极可以排列成一行多列结构。其中，第一电极的列方向即为条状电极的纵向延伸方向，即图3、图4中所示的Y方向；第一电极的行方向即为条状电极的横向并排方向，即图3、图4中所示的X方向。在一些实施例中，列方向可以为条状电极的横向并排方向，即如图5所示的X方向，行方向为条状电极的纵向延伸方向，即如图5所示的Y方向。
在一些实施例中，第一电极的列方向可以与第一发光块311的行方向相同或者垂直。如图4所示，第一发光块311的行方向为X方向，第一电极的列方向为Y方向，则第一发光块311的行方向与第一电极的列方向垂直。如图5所示，第一发光块311的行方向为X方向，第一电极的列方向也为X方向，则第一发光块311的行方向与第一电极的列方向平行。
在一实施例中，如图4至图6所示，第一电极层2还可以包括多个对应第二发光区32设置的第二电极24，第二电极24上可以对应多个第二发光块321。在一实施例中，第二发光块321的列方向可以与第一电极21的列方向垂直，如图5所示，第二发光块321的列方向为Y方向，而第一电极21的列方向为X方向。在另一实施例中，第二发光块321的列方向可以与第一电极21的列方向相同，且在该列方向上，第一电极21的宽度大于或等于第二电极24的宽度。如图4和图6所示，第一电极21、22和23的列方向均为Y方向，且第二发光块321的列方向也为Y方向，则在Y方向上，第一电极21的宽度的D1大于或等于第二电极24的宽度D2，即D1≥D2。其中，D1可以等于D2，如图4所示；或者，D1可以大于D2，如图6所示。
由于第一电极21的宽度相对第二电极24的宽度较大，因此第一发光块311的面积相对较大，有利于增加第一发光块311的开口率，从而加大发光强度，以有效弥补由于 第一发光区31为透明区而双向透光导致亮度降低的弊端。当然，在此仅以Y向为第一电极和第二发光块321的列方向为例进行说明，在其他实施例中，也可以是整体旋转90°，以X方向为第一电极和第二发光块321的列方向。
图7至图10A是本申请根据不同示例性实施例示出的阵列基板上第一发光区的结构示意图。在一实施例中，如图7所示，第一电极可以沿第一方向对应多列第一发光块311，该第一方向可以为第一电极的纵向延伸方向，即图7所示的Y方向。基于此，在第一发光区31的像素密度不变的情况下，可以在降低掩膜形变量的同时，有效减少第一电极的数量，从而降低加工难度。
在一实施例中，在与第一方向垂直的第二方向上，即在图7所示的X方向上，同一第一电极上相邻的两个第一发光块311对齐设置；或者，如图8所示，同一第一电极上沿X方向相邻的两个第一发光块311错位设置。相对于图7所示的对齐设置的方式，图8所示的错位设置的方式能够提高第一发光块311排布的均匀性，有效提升显示效果。
在一实施例中，如图8所示，相邻的两个第一电极上对应的第一发光块311可以对齐设置。在一实施例中，如图9所示，相邻的两个第一电极上对应的第一发光块311也可以错位设置。
在一实施例中，同一第一电极上相邻的两个第一发光块311的中轴线在第二方向上的间距为第一发光块311在该第二方向上尺寸的0.5-2倍。如图8所示，在X方向上相邻的第一发光块311A与第一发光块311B错位设置，且第一发光块311A与第一发光块311B中轴线在Y方向上的间距为D3，D3等于第一发光块311B在Y方向上的长度D4。在一实施例中，如图9所示，D3＝1.5*D4。在一实施例中D3还可以是D4的0.5倍、0.8倍、1.2或者2倍。
在一实施例中，如图9和图10A所示，第一电极23可以包括多个第一子电极231，该多个第一子电极231在Y方向上错位排列。每一第一子电极231可以包括多个块状电极或者条状电极。在一实施例中，如图9所示，第一电极23可以包括第一子电极231和第二子电极232。其中，第一子电极231可以包括多个块状电极2311。在一实施例中，块状电极2311与第一发光块之间一一对应；或者，单个块状电极2311可以对应多个第一发光块311。第二子电极232可以包括多个块状电极2321。
在一实施例中，如图9和图10A所示，第一电极23还可以包括连接部233，该连接部233连接相邻的两个子电极。如图10A所示，通过连接部23电性连接相邻的两个子 电极231、232，可以得到沿X方向延伸且呈波浪形的第一电极23。在一些实施例中，X方向和Y方向可以进行适应性调整，如方向互换或整体旋转90°等。
图10B是本申请根据一示例性实施例示出的阵列基板的局部结构示意图。第一电极21、22、23在第一发光区31内可以排布成如图10B所示的三行两列的结构。在一些实施例中，第一电极在第一发光区内也可以排布成两行两列、三行三列的结构等。在一实施例中，在同一行的所有第一电极上可以对应颜色相同的第一发光块311。在一些实施例中，也可以在同一列的所有第一电极上对应颜色相同的第一发光块311。
在一实施例中，第一电极层2可以为阳极、第二电极层4可以为阴极。在一些实施例中，第二电极层4可以为面电极，能够有效简化加工难度。
图11至图13B是本申请根据一示例性实施例示出的阵列基板的截面示意图。在一实施例中，如图11所示，第二电极层4可以包括透明材料层41和金属层42。其中，透明材料层4可以覆盖第一发光区31和第二发光区32，而金属层42可以覆盖第二发光区32。其中整个透明材料层41是在同一工艺中形成。其中，在第二发光区32设置金属层42可以降低第二电极层4的电阻，从而有效降低压降。
在一实施例中，如图12所示，第二电极层4可以包括第三电极43和第四电极44。其中，第三电极43可以对应第一发光区31设置，第四电极44可以对应第二发光区31设置。其中，该第三电极43可以为透明材料层，第四电极可以为金属层。在一实施例中，如图13A所示，第三电极43和第四电极44均可以为金属层，且第一发光区31对应的第三电极43的金属层厚度小于第二发光区32对应的第四电极44的金属层厚度。
上述实施例中，透明材料层可以采用氧化铟锡、氧化铟锌、掺杂银的氧化铟锡和掺杂银的氧化铟锌中一种或者多种制成；金属层可以采用Mg、Ag和Al中的一种或者多种制成，如可以采用纯金属制成或者合金制成，例如MgAg系合金。能够有效提高第一发光区31的透光率，进而有利于提升位于第一发光区31下方的摄像头的拍照效果。在一实施例中，如图13B所示，所述第二电极层还可以包括对应所述第一发光区31设置的第五电极45。在一实施例中第五电极45可以为面电极；
在一实施例中，第五电极45可以为单层结构或叠层结构。第五电极45为单层结构时，第五电极45可以为单层金属层、单层金属混合物层或单层透明金属氧化物层；第五电极45为叠层结构时，第五电极45可以为透明金属氧化物层与金属层的叠层或透明金属氧化物层与金属混合物层的叠层。
在一实施例中，第五电极45的材料中掺杂有金属，第五电极45的厚度大于或等于100埃且小于或等于500埃，进一步地，第五电极45的厚度大于或等于100埃且小于或等于200埃，第五电极45的厚度整体连续，第五电极45的透明度大于40％，使得第一发光区31的透光率能够有效提升。
在一实施例中，第五电极45的材料中掺杂有金属，第五电极45的厚度大于或等于50埃，小于或等于200埃时，所述第五电极45的厚度整体连续，且所述第五电极45的透明度大于50％，进一步地，第五电极45的透明度大于60％。
在一实施例中，第五电极45可以为单层结构，其中，单层金属层材料可以为Al或Ag；单层金属混合物层材料可以为MgAg或掺杂Al的金属混合材料；透明金属氧化物可以为ITO或IZO。
在一实施例中，如图13A所示，第三电极43为金属层，其厚度可以大于10埃，并形成一整体连续的面电极，且金属层的透明度>40％；进一步地，金属层的厚度可以大于50埃，并形成一整体连续的面电极，且金属层的透明度>50％。
在一实施例中，第一电极层2和第二电极层4均可以采用透明材料制成。在一实施例中，透明材料的透光率可以大于等于90％。其中，透明材料可以包括氧化铟锡、氧化铟锌、掺杂银的氧化铟锡和掺杂银的氧化铟锌中至少一种。如此使得第一发光区31的透光率能够有效提升，例如可以使得透光率为80％以上。
在一实施例中，发光层3可以包括有机发光材料层和公共层。其中，有机发光材料层可以包括多个独立的个体，以形成第一发光块。公共层可以包括空穴注入层、空穴传输层、电子传输层及电子注入层，该空穴注入层、空穴传输层、电子传输层及电子注入层中的至少一层覆盖第一电极层2以及相邻第一电极之间的间隙，从而可以通过该公共层中的一层或者多层隔离第一电极层2和第二电极层4，避免短路。
图14-20是本申请根据不同示例性实施例示出的阵列基板上第一发光区的结构示意图。在一实施例中，如图14所示，第一电极的列方向(图14中的Y方向)上的两条边均可以为波浪形，且两条边的波峰相对设置、波谷相对设置。如此使得相邻两列第一电极的间隙在列方向呈现为连续变化或者间断变化。第一电极21在列方向上，无论其宽度是连续变化还是间断变化都可以为周期性变化，一个变化周期的长度可以对应于一个像素的宽度。
第一发光区31可以设置有多行波浪形的第一电极，以在列方向上，第一电极的宽度 连续变化或者间断变化，从而使得相邻两列第一电极具有连续变化的间距或者间断变化的间距。因此在第一电极的不同宽度位置以及相邻两列第一电极的不同间距之间，产生的衍射条纹的位置不同，不同位置处的衍射效应相互抵消，从而可以有效减弱衍射效应，进而有利于提升位于该第一发光区31下方的摄像头的拍照效果。
在一实施例中，如图14所示，其中，第一电极呈多行多列排布，Y方向为第一电极的列方向、X方向为第一电极的行方向。每一第一电极均可以包括一个或者多个波峰和一个或者多个波谷。以第一电极21为例，图14中T所示位置处为波峰，B所示位置处为波谷。其中，第一电极的两条边的波峰相对处的宽度D5在30μm至(A-X)μm之间；第一电极的两条边的波谷相对处的宽度D6大于X，且小于波峰相对处的宽度D5，其中A为第一发光块大小，X为电极尺寸最小处的宽度值，且A大于或等于(30+X)μm。在一实施例中，X可以为4微米；在一实施例中，X可以小于4微米。
由于第一电极的边呈波浪形变化，从而导致相邻第一电极之间的间距亦随之产生变化。在一实施例中，如图14所示，两列第一电极的波峰相对处具有最小间距W1，并在两列第一电极的波谷位置相对处具有最大间距W2。其中，最小间距W1为(A-D5)，最大间距W2为(A-D6)。
在一些实施例中，第一电极21在衬底上的投影的形状可以包括至少一个第一图形单元，从而可以形成上述的波峰和波谷。第一图形单元可以为圆形、椭圆形、哑铃形、葫芦形或矩形。如图14和图15所示，每一第一电极21可以由多个圆形组成；在一实施例中，如图16所示，第一电极21可以由多个椭圆形组成；在一实施例中，如图17所示，第一电极21可以由多个哑铃形组成。在一些实施例中，第一电极21还可以由多个葫芦形组成，其中葫芦形可以由两个圆形组成。在一实施例中，第一电极21也可以是由一个第一图形单元组成。如图18中所示，每个第一电极21均由一个葫芦形图形单元组成。在一实施例中，如图19所示，由于每个第一电极21均由一个椭圆形的图形单元组成，那么，第一电极21仅包括波峰，不存在波谷，相应的，两列第一电极间仅存在最小间距。
在一实施例中，第一发光块311在衬底上的投影的形状可以包括至少一个第二图形单元，从而可以形成上述的波峰和波谷。该第二图形单元可以包括圆形、椭圆形、哑铃形、葫芦形或矩形。如图20所示，第一发光块311可以为矩形。
在一实施例中，第一电极21与第一发光块311的形状可以相同或不同。如图14所示，第一电极21上对应的第一发光块311的形状与该第一电极21的形状类似，均为由 多个圆形组成的形状。在一实施例中，如图15所示，第一电极21上对应的第一发光块311形状与该第一电极21的形状不同，第一电极21为有多个圆形组成的形状，而第一发光块311为长方形，或者在一实施例中，第一发光块311也可以为圆形或者椭圆形等。在一实施例中，如图20所示，第一电极21与第一发光块311均为矩形；在一实施例中，该呈矩形的第一电极21上对应的第一发光块311还可以是圆形或者椭圆形等。
图21是本申请根据一示例性实施例示出的一种阵列基板的截面示意图。在一实施例中，如图21所示，该阵列基板100还可以包括像素限定层5，该像素限定层5形成于第一电极层2上，并且包括对应于第一发光区31设置的多个第一像素限定孔51。在一实施例中，每一像素限定孔51内可以设置多个第一发光块311，如图21所示；或者，在一实施例中，每一像素限定孔51内也可以设置一个第一发光块311，可以有效降低相邻第一发光块311之间的混色风险。
图22-26是本申请根据不同示例性实施例示出的阵列基板上的结构示意图。如图22所示，像素限定层5还可以包括对应于第二发光区32设置的多个第二像素限定孔52。在一实施例中，第二像素限定孔可以与第二发光块之间一一对应，或者也可以是单个第二像素限定孔内对应多个第二发光块。
在一实施例中，第二像素限定孔52的尺寸等于或小于第一像素限定孔51的尺寸。如图22所示，第一像素限定孔51和第二像素限定孔52的尺寸相等，可以有效降低对掩膜的加工难度；或者，如图23所示，第一像素限定孔51的尺寸可以大于第二像素限定孔52的尺寸，从而相邻第一像素限定孔51之间的间距等于相邻第二像素限定孔52之间的间距时，第一像素限定孔51的分布密度相对较小，第一像素限定孔51之间的间隙数量少，能够有效降低光线的衍射概率。在一实施例中，像素限定层5可以整体采用透明有机材质制成；或者，像素限定层5也可以采用透明无机材质制成；或者，像素限定层5对应第一发光区31的一段可以采用透明材质制成，而对应第二发光区32的一段可以采用非透明材质制成。
在一实施例中，如图24所示，多个第一发光块311和多个第二发光块321均设置多列，并且第一发光块311的列和第二发光块321的列一一对应，如此可以使得第一发光区31的分布密度相对较大。在一实施例中，如图24所示，多个第一发光块311和多个第二发光块321的列方向为Y方向；在一些实施例中，多个第一发光块311和多个第二发光块321的列方向可以为X方向。
在一实施例中，同一列第一发光块311的颜色与该列第二发光块321中靠近第一发 光区31的第一个第二发光块321颜色相同，可以降低对第一发光区31的工艺要求，有效避免第一发光区31在同一列方向的混色风险。如图24所示，第一发光块311C和第一发光块311D组成一列，在该列中的第二发光块中靠近第一发光区31的第二发光块321A与第一发光块311C和第一发光块311D的颜色相同。即，当第二发光块321A为蓝色时，第一发光块311C和第一发光块311D均为蓝色；或者，当第二发光块321A为绿色时，第一发光块311C和第一发光块311D均为绿色；或者，当第二发光块321A为红色时，第一发光块311C和第一发光块311D均为红色。
在一实施例中，一列第二发光块中靠近第一发光区31设置的一个或者多个第二发光块321和该列第一发光块311中相邻的一个或者多个第一发光块311组成一个像素重复单元。在一实施例中，像素重复单元可以包括三原色，如图25所示，第二发光块321A、第一发光块311C和第一发光块311D可以组成一个包括红色、绿色和蓝色色块的像素重复单元(如图25中虚线框所示)；在一实施例中，如图26所示，第二发光块321A、第二发光块321B和第一发光块311C可以组成一个包括红色、绿色和蓝色色块的像素重复单元(如图26中虚线框所示)。如此可以在第一发光区31和第二发光区32的交界处进行显示过渡，提升显示效果。在一些实施例中，该像素重复单元也可以包括两个原色，例如红色和绿色、红色和蓝色或者绿色和蓝色。在一些实施例中，像素重复单元也可以包括四个或者四个以上的原色，相应的，组成该像素重复单元的第一发光块311和第二发光块321的数量可以相应进行调整。
图27是本申请根据一示例性实施例示出的显示面板的截面示意图。如图27所示，本申请还提供一种显示面板200，该显示面板200可以包括封装层201和上述任一项实施例中所述的阵列基板100。封装层201位于阵列基板100上远离衬底的一侧。在显示面板100上可以形成对应于第一发光区31设置的透明显示区域和对应于第二发光区设置的非透明显示区域。透明显示区域的下方可以放置感光器件，该感光器件可以通过该透明显示区域采集外部光线，或者向外发射光线。在一实施例中，当感光器件处于工作状态时，透明显示区域可以切换至非显示状态，当感光器件处于关闭状态时，透明显示区域可以切换至显示状态。在一实施例中，该封装层201可以包括偏光片(图中未示出)，该偏光片可以覆盖第二发光区对应的区域，且未覆盖第一发光区对应的区域，以避免偏光片的设置影响外部的入射光线和/或电子设备发出的光线。
在一实施例中，阵列基板100的第一发光区至少部分被第二发光区包围，如图27所示，该显示面板200还可以包括芯片组件202，该芯片组件202可以用于控制第一发 光块和第二发光块的显示状态，并且能够使得位于第一发光区和第二发光区交界处的第一发光块和第二发光块颜色一致，从而在视觉上减弱透明显示区域和非透明显示区域之间的差异，有效提升用户的视觉效果。
图28是本申请根据一示例性实施例示出的显示装置的截面示意图。如图28所示，本申请提供一种显示装置300，该显示装置300可以包括装置本体301和上述任一项实施例所述的显示面板200，显示面板200设置在装置本体301上，且与该装置本体301相互连接。其中，显示面板200可以采用前述任一实施例中的显示面板，用以显示静态或者动态画面。
图29是本申请根据一示例性实施例示出的显示装置的结构示意图。如图29所示，设备本体301可以包括一器件区3011，该器件区3011可以设置有如摄像头400以及光传感器等感光器件。显示面板200的透明显示区域对应于器件区3011设置，以使得感光器件能够透过第一发光区对外部光线进行采集等操作。由于第一发光区中的显示面板能够有效改善外部光线透射该第一发光区时所产生的衍射效应，从而可有效提升显示装置上摄像头400所拍摄图像的质量，避免因衍射而导致的图像失真，同时也能提升光传感器感测外部光线的精准度和敏感度。
该显示装置可以为液晶显示装置、电子纸、手机、平板电脑、电视机、显示器、笔记本电脑、数码相框或导航仪等任何具有显示功能的产品或部件。
