本实施例中，所述第一电极层113例如为阳极层，并包括与所述发光单元一一对应设置的多个阳极单元。
本实施例中，所述第二电极层116例如为阴极层，所述第二电极层116包括：设置在所述第一显示区11中的多个第一透光孔201，所述第一透光孔201位于相邻所述第一像素重复单元20之间。本申请通过对所述第二电极层116进行图案化设计，以在所述第二电极层116上形成与相邻所述第一像素重复单元20之间的间隙区域对应设置的第一透光孔201，从而能够减弱外界环境光在穿过相邻所述第一发光单元21之间的间隙区域时第二电极层116对所述外界环境光的滤光效果，减少光损失，有效提高所述第一显示区11的透光率，提高所述光学元件200的采光量，提升所述摄像头的成像效果。
本实施例中，所述显示面板100还包括驱动电路层，所述驱动电路层设置在所述衬底基板101和所述发光层115之间，其中，所述驱动电路层包括：设置在所述第一显示区11中的多个第二透光孔202，所述第二透光孔202与所述第一透光孔201对应设置。本申请通过在所述驱动电路层上形成与所述第一透光孔201对应设置的第二透光孔202，从而能够减弱外界环境光在穿过相邻所述第一发光单元21之间的间隙区域时驱动电路层对所述外界环境光的滤光效果，减少光损失，有效提高所述第一显示区11的透光率，提高所述光学元件200的采光量，提升所述摄像头的成像效果。
本实施例中，所述驱动电路层包括依次层叠设置于所述衬底基板101上的缓冲层102、薄膜晶体管层、平坦层和像素定义层114，其中，所述缓冲层102例如为无机材料形成的膜层；所述薄膜晶体管层中形成有薄膜晶体管和金属走线构成的像素驱动电路，所述薄膜晶体管的类型包括低温多晶硅、金属氧化物半导体和非晶硅中的至少一种，作为示例，所述薄膜晶体管层包括依次层叠设置在所述缓冲层102上的有源半导体层103、第一无机绝缘层104、第一金属层105、第二无机绝缘层106、第二金属层107、第三无机绝缘层108和第三金属层109；所述平坦层可以为单层或复合层的有机层，作为示例，所述平坦层包括第一平坦层110和第二平坦层112；所述像素定义层114包括与所述发光单元一一对应设置的像素定义开口，所述发光单元设置于所述像素定义开口内。
本实施例中，所述第二透光孔202可以形成在所述薄膜晶体管层、平坦层、像素定义层114中的至少一层中，且当所述第二透光孔202形成在所述薄膜晶体管层中时，所述第二透光孔202可以形成在所述薄膜晶体管层中的至少一个子膜层中，所述子膜层例如包括第一无机绝缘层104、第二无机绝缘层106和第三无机绝缘层108；当所述第二透光孔202形成在所述平坦层中时，所述第二透光孔202可以形成在所述平坦层中的至少一个子膜层中，所述子膜层例如包括第一平坦层110和第二平坦层112。
作为示例，图3是本申请实施例一提供的显示面板的第一种截面示意图；图6是本申请实施例一提供的显示面板的第二种截面示意图；图7是本申请实施例一提供的显示面板的第三种截面示意图。图3、图6和图7中的第二透光孔202所贯穿的膜层结构不同，具体的，结合图3、图6和图7所示，所述第二透光孔202可以为贯穿所述像素定义层114、所述平坦层和所述薄膜晶体管层的通孔，或所述第二透光孔202可以为贯穿所述像素定义层114、所述平坦层、所述薄膜晶体管层中的第三无机绝缘层108和第二无机绝缘层106的通孔，或所述第二透光孔202可以为贯穿所述像素定义层114、所述平坦层中的第二平坦层112的通孔。
本实施例中，基于工艺制程的限制，所述第二电极层116可以覆盖所述第二透光孔202的至少部分侧壁（图中未示出）。在实际应用中，为了便于通过激光工艺来进行第二电极层116的图案化处理，会先在驱动电路层中形成第二透光孔202，并在第二透光孔202底面设置金属牺牲层，然后在所述驱动电路层上覆盖发光层（例如电子传输层、空穴传输层等）和第二电极层116，再通过激光从衬底基板101侧对金属牺牲层进行加热，加热膨胀后的金属牺牲层会带动其上的发光层和第二电极层116脱落，进而形成第二电极层116的第一透光孔201，但此时会存在有部分第二电极层116仍覆盖在第二透光孔202的至少部分侧壁。由此可知，驱动电路层中形成第二透光孔202不仅可以便于提高第一显示区11的透光率，同时也会方便第二电极层116的激光图案化工艺实现。
如图3所示，本实施例中，所述发光层115例如仅包括设置在所述像素定义开口内的发光单元。但在本申请的其他实施例中，所述发光层115除包括设置在所述像素定义开口内的发光单元外，还可以包括设置在像素定义开口外的不发光部分（例如由主体材料和掺杂材料构成的发光材料可以仅设置在像素定义开口中，而其他的功能材料如电子传输层、空穴传输层等会覆盖整个面板，而不仅限于像素定义开口中，而这部分材料无法独立发光）。此种情况下，所述发光层115包括：设置在所述第一显示区11中的多个第三透光孔，所述第一透光孔201通过所述第三透光孔与所述第二透光孔202连通，所述第三透光孔分别与所述第一透光孔201、第二透光孔202对应设置。本申请通过在所述发光层115上形成所述第三透光孔，从而能够减弱外界环境光在穿过相邻所述第一发光单元21之间的间隙区域时发光层115对所述外界环境光的滤光效果，减少光损失，有效提高所述第一显示区11的透光率，提高所述光学元件200的采光量，提升所述摄像头的成像效果。
本实施例中，所述显示面板100还包括彩膜层，所述彩膜层设置在所述第二电极层116远离所述衬底基板101的一侧。具体的，所述彩膜层包括：遮光层119和色阻120，其中，所述遮光层119包括：与所述第一发光单元21对应设置的第一开孔、与所述第二发光单元31对应设置的第二开孔，所述色阻120填充所述第一开孔和所述第二开孔。也即，位于所述第一开孔和所述第二开孔内的所述色阻120与所述第一发光单元21和所述第二发光单元31对应设置。本申请通过在所述第二电极层116远离所述衬底基板101的一侧设置彩膜层，所述彩膜层能够实现抗反射功能的同时，厚度相较于常规技术中的偏光片而言更薄，从而能够避免在所述显示面板100中设置厚度较厚的偏光片，以减薄所述显示面板100的整体厚度。
本实施例中，所述遮光层119还包括：设置在所述第一显示区11中的多个第四透光孔204，所述第四透光孔204与所述第一透光孔201对应设置。本申请通过在所述遮光层119上形成与所述第一透光孔201对应设置的第四透光孔204，从而能够使外界环境光顺利穿过所述遮光层119，并射入到所述光学元件200中，保证所述摄像头能够正常实现成像功能。
本实施例中，所述第一像素重复单元20在第一显示区11中的分布密度，与所述第二像素重复单元30在所述第二显示区12中与所述第一显示区11形状、面积相同的区域上的分布密度相同。也即，所述第一显示区11中的第一像素重复单元20的数量，与所述第二显示区12中与所述第一显示区11形状、面积相同的区域上的第二像素重复单元30的数量相同。在实际应用中，第一像素重复单元20和第二像素重复单元30的排布方式也可以相同，且相邻两个第一像素重复单元20的中心点的间距与相邻两个第二像素重复单元30的中心点的间距也可以相同。
相应的，由于每个所述第一像素重复单元20包含的第一发光单元21的数量与每个所述第二像素重复单元30包含的第二发光单元31的数量相同。因此，所述第一发光单元21在所述第一显示区11中的分布密度，与所述第二发光单元31在所述第二显示区12中与所述第一显示区11形状、面积相同的区域上的分布密度也相同，也即所述第一显示区11中的第一发光单元21的数量与所述第二显示区12中与所述第一显示区11形状、面积相同的区域上的第二发光单元31的数量相同，从而能够弱化所述第一显示区11和所述第二显示区12的画面显示差异。
相应的，单位面积内，所述第一发光单元21的分布密度与所述第二发光单元31的分布密度不同。具体的，单位面积内，所述第一发光单元21的分布密度大于所述第二发光单元31的分布密度，所述单位面积例如为所述第一像素重复单元20的面积，也即，在对应所述第一像素重复单元20的单位面积内，所述第一发光单元21的分布更紧凑，从而能够使相邻所述第一像素重复单元20之间的间隔距离大于相邻所述第二像素重复单元30之间的间隔距离，并为在所述第一像素重复单元20之间的间隙区域设置透光结构创造条件。
本实施例中，所述第一像素重复单元20中的多个所述第一发光单元21的排布方式与所述第二像素重复单元30中的多个所述第二发光单元31的排布方式相同（这里的排布方式是指第一发光单元21或第二发光单元31阵列排布的关系相同，但不限定相邻第一发光单元21的间距与相邻第二发光单元31的间距也相同。例如图4和图5中，蓝色发光单元B和红色发光单元R交替排成一列，绿色发光单元G排成相邻的另一列，且绿色发光单元G在蓝色发光单元B和红色发光单元R之间）。具体的，图8是图2中A1处的第一像素重复单元和第一透光孔的第二种位置示意图。其中，图8中的每个第一像素重复单元20包含的第一发光单元21的数量，与图4中的每个第一像素重复单元20包含的第一发光单元21的数量相同；图8中的每个第一像素重复单元20中的第一发光单元21的排布方式，与图4中的每个第一像素重复单元20中的第一发光单元21的排布方式相同。与图4不同的是，图8所示的第一像素重复单元20的面积与图4所示的第一像素重复单元20的面积存在差异，图8所示的第一透光孔201的面积与图4所示的第一透光孔201的面积存在差异。
结合图4、图5和图8所示，所述第一像素重复单元20中的两个相邻所述第一发光单元21之间的间隔距离小于所述第二像素重复单元30中的相对应的两个相邻所述第二发光单元31之间的间隔距离。
优选的，每个所述第一像素重复单元20中的多个所述第一发光单元21包括：显示第一颜色的第一子像素、显示第二颜色的第二子像素和显示第三颜色的第三子像素；每个所述第二像素重复单元30中的多个所述第二发光单元31包括：显示第一颜色的第四子像素、显示第二颜色的第五子像素和显示第三颜色的第六子像素。其中，每个所述第一像素重复单元20中的两个相邻所述第一子像素之间的间距小于每个所述第二像素重复单元30中的两个相邻所述第四子像素之间的间距；每个所述第一像素重复单元20中的两个相邻所述第二子像素之间的间距小于每个所述第二像素重复单元30中的两个相邻所述第五子像素之间的间距；每个所述第一像素重复单元20中的两个相邻所述第三子像素之间的间距小于每个所述第二像素重复单元30中的两个相邻所述第六子像素之间的间距。
本实施例中，每个所述第一像素重复单元20所包含的不同发光颜色的发光单元的种类与每个所述第二像素重复单元30所包含的不同发光颜色的发光单元的种类相同。优选的，每个所述第一像素重复单元20包含三种不同发光颜色的第一发光单元21，每个所述第二像素重复单元30亦包含三种不同发光颜色的第二发光单元31，所述三种不同发光颜色分别为第一颜色、第二颜色和第三颜色。
进一步的，每个所述第一像素重复单元20中，任意一种发光颜色的第一发光单元21的数量，与每个所述第二像素重复单元30中的、具有同种发光颜色的第二发光单元31的数量相同。也即，每个所述第一像素重复单元20中的第一子像素的数量与每个所述第二像素重复单元30中的第四子像素的数量相同；每个所述第一像素重复单元20中的第二子像素的数量与每个所述第二像素重复单元30中的第五子像素的数量相同；每个所述第一像素重复单元20中的第三子像素的数量与每个所述第二像素重复单元30中的第六子像素的数量相同。
本实施例中，发光颜色相同的所述第一发光单元21和所述第二发光单元31中，所述第一发光单元21的面积可以小于所述第二发光单元31的面积。本申请通过缩小所述第一发光单元21的面积以进一步提升所述显示面板100的第一显示区11的透光率。当然，也可以根据实际需求将第一发光单元21的面积设计成大于或等于第二发光单元31的面积，来增强第一显示区11的显示效果，这里不做限制。
当然，本申请对所述第一像素重复单元20中的多个所述第一发光单元21的排布方式不作限制。图9是图2中A1处的第一像素重复单元和第一透光孔的第三种位置示意图；图10是图2中A1处的第一像素重复单元和第一透光孔的第四种位置示意图；图11是图2中A1处的第一像素重复单元和第一透光孔的第五种位置示意图。参照图9-图11所示，本申请提供的所述显示面板中，所述第一像素重复单元20中的多个所述第一发光单元21的排布方式还可以与所述第二像素重复单元30中的多个所述第二发光单元31的排布方式不同。由于所述第一像素重复单元20中的多个所述第一发光单元21不再局限于与所述第二像素重复单元30中的多个所述第二发光单元31的排布方式相同，而可以任意排列，因此，能够进一步收缩所述第一像素重复单元20内各第一发光单元21之间的间隙距离，进一步缩小所述第一像素重复单元20的面积，以进一步提高所述第一显示区11的透光率。
下面对所述第一显示区11和所述第二显示区12的相对位置关系进行详细说明。本实施例中，所述显示面板100的第一显示区11与所述第二显示区12间隔设置，所述显示面板100还包括位于所述第一显示区11和所述第二显示区12之间的过渡显示区13，所述过渡显示区13设置有与各所述第一发光单元21电性连接的多个像素驱动电路。由于所述过渡显示区13不存在透光功能的需求，本申请通过将与所述第一发光单元21电性连接的、用于驱动所述第一发光单元21的像素驱动电路设置在过渡显示区13，从而能够进一步提升所述第一显示区11的透光率。
本实施例中，所述过渡显示区13的所述像素驱动电路通过透明金属走线111与所述第一发光单元21电性连接。
进一步的，每个所述第一像素重复单元20中，显示同种颜色的多个所述第一发光单元21与同一像素驱动电路电性连接。此种情况下，用于驱动每个所述第一像素重复单元20中的多个第一发光单元21的像素驱动电路的数量，能够少于每个所述第一像素重复单元20中的第一发光单元21的数量，从而大大减少所述过渡显示区13的像素驱动电路布局难度，降低生产制造成本。当然，在本申请的其他实施例中，每个所述第一发光单元21均与其对应的一个所述像素驱动电路性电连接，也即每个所述像素驱动电路对应连接一个所述第一发光单元21。
本实施例中，每个所述第一像素重复单元20中的多个所述第一发光单元21包括：显示第一颜色的两个第一子像素、显示第二颜色的两个第二子像素和显示第三颜色的四个第三子像素，其中，所述第一子像素的面积和所述第二子像素的面积均大于所述第三子像素的面积。
优选的，所述第一子像素显示的颜色为蓝色，所述第二子像素显示的颜色为红色，所述第三子像素显示的颜色为绿色。也即，每个所述第一像素重复单元20包括8个第一发光单元21，所述8个第一发光单元21分别为两个蓝色发光单元B、两个红色发光单元R和四个绿色发光单元G。当然，本申请对所述第一像素重复单元20包含的第一发光单元21的数量不作限制，在本申请的其他实施例中，所述第一像素重复单元20还可以包括其他数量的第一发光单元21，所述其他数量例如为4，所述4个第一发光单元21分别为一个蓝光发光单元B、一个第一红色发光单元R和两个绿色发光单元G。
本实施例中，所述显示面板100例如还包括封装层117，所述封装层117用于保护所述发光层115，防止外界水氧入侵到所述显示面板100内部。具体的，所述封装层117设置在所述第二电极层116和所述彩膜层之间，并与所述第二电极层116邻接设置，所述封装层117可以为多个无机封装层和有机封装层层叠形成的复合膜层。
本实施例中，所述显示面板100例如还包括触控层118，所述触控层118用于执行触控功能，其触控模式可以为互容或自容，所述触控层118的材料可以为透明导电材料或网格状金属。具体的，所述触控层118设置在所述封装层117和所述彩膜层之间，并与所述封装层117邻接设置。
本实施例中，所述显示装置还可以包括位于所述显示面板100一侧的盖板121，所述盖板121与所述显示面板100中的彩膜层邻接设置；所述显示装置还可以包括位于所述显示面板100另一侧的背板和散热层（图中未示出），所述背板位于所述衬底基板101和所述散热层之间，且所述背板与所述衬底基板101邻接设置。
实施例二
图12是本申请实施例二提供的显示面板的俯视示意图；图13是图12中A1处的第一像素重复单元和第一透光孔的第一种位置示意图；图14是图12中A1处的第一像素重复单元和第一透光孔的第二种位置示意图；图15是图12中A1处的第一像素重复单元和第一透光孔的第三种位置示意图。结合图1、图12-图15所示，本申请实施例二提供一种显示装置10，所述显示装置10包括光学元件200和显示面板100，其中，所述光学元件200位于所述显示面板100的一侧，并与所述显示面板100的所述第一显示区11对应设置。所述显示面板100的结构与本申请实施例一中的显示面板100结构相类似，本申请实施例二对于相同部分不再一一赘述。
不同的是，与所述第一发光单元21电性连接的像素驱动电路设置的位置与实施例一存在不同。具体的，所述第一显示区11中设置有与所述第一发光单元21电性连接的像素驱动电路，所述像素驱动电路与所述第一像素重复单元20重叠设置。本申请实施例二提供的显示面板100通过将与所述第一发光单元21电性连接的像素驱动电路和所述第一发光单元21重叠设置，在前文设计满足第一显示区11透光率需求的前提下，可以将与第一发光单元21电性连接的像素驱动电路设置在第一发光单元21下面，无需设置额外的透明金属走线111，降低第一显示区11的布线设计难度，还具有简化膜层结构，减少制程工艺次数的效果。
综上所述，本申请公开了一种显示面板及显示装置，显示面板包括：第一显示区和围绕第一显示区设置的第二显示区，第一显示区阵列设置有多个第一像素重复单元，每个第一像素重复单元包括多个第一发光单元；第二显示区阵列设置有多个第二像素重复单元，每个第二像素重复单元包括多个第二发光单元；其中，第一像素重复单元包含的第一发光单元的数量和第二像素重复单元包含的第二发光单元的数量相同，且第一像素重复单元的面积小于第二像素重复单元的面积。本申请通过将位于第一显示区的固定数量的第一发光单元组合成第一像素重复单元，将位于第二显示区的对应数量的第二发光单元组合成第二像素重复单元，并使所述第一像素重复单元的面积小于所述第二像素重复单元的面积，从而能够使相邻第一像素重复单元之间的间隙区域的面积大于相邻第二像素重复单元之间的间隙区域的面积，从而便于在相邻第一像素重复单元之间的间隙区域进行膜层结构设计，并设置透光结构，以提高第一显示区的透光率。
以上对本申请实施例所提供的一种棱镜膜及显示装置进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的方法及其核心思想；同时，对于本领域的技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
