具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
在本申请的描述中，需要理解的是，术语“中心”、“横向”、“上”、“下”“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”以及“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。此外，需要说明的是，当元件被称为“形成在另一元件上”时，它可以直接连接到另一元件上或者可能同时存在居中元件。当一个元件被认为是“连接”另一个元件，它可以直接连接到另一元件或者同时存在居中元件。相反，当元件被称作“直接在”另一元件“上”时，不存在中间元件。
申请人发现，将摄像头等感光器件设置在透明显示面板下方时，拍照得到的照片模糊。申请人经过研究发现，出现这个问题的原因在于，电子设备的显示屏体内有导电走线，外部光线经过这些导电走线时会使得衍射强度分布较为复杂，从而出现衍射条纹，进而影响摄像头等感光器件的正常工作。例如，位于透明显示区域之下的摄像头工作时，外部光线经过显示屏内的导线材料走线后会发生较为明显的衍射，从而使得摄像头拍摄到的画面失真。
为解决上述问题，本申请一实施例提供了一种显示面板。图1为一实施例中显示面板的剖视图。该显示面板包括基板110以及形成在基板110上的像素定义层120。像素定义层120上形成有像素开口130，以定义出像素的发光区域。在本实施例中所提及的像素均为最小的像素单位，如子像素。
像素开口130包括第一类型像素开口。第一类型像素开口在基板上的投影的各边互不平行且各边均为曲线，也即第一类型像素开口在各个方向上均具有变化的宽度且在同一位置具有不同的衍射扩散方向。光在穿过狭缝、小孔或者圆盘之类的障碍物时，会发生不同程度的弯散传播，从而偏离原来的直线传播，这种现象称之为衍射。衍射过程中，衍射条纹的分布会受到障碍物尺寸的影响，例如狭缝的宽度、小孔的尺寸等。具有相同宽度的位置处产生的衍射条纹的位置一致，从而产生较为明显的衍射效应。在本实施例中，当外部光线经过该第一类型像素开口时，在不同宽度的位置上能够产生具有不同位置和扩散方向的衍射条纹，因此不会产生较为明显的衍射效应，从而可以确保设置于该显示面板下方的感光元件能够正常工作。
传统的像素定义层上的像素开口均根据像素大小设置成长方形或者正方形。长方形存在两组相互平行的边，两条长边之间的距离处处相等，两条短边之间的距离也处处相等。因此，当外部光线经过该像素开口时，在长边方向或者短边方向的不同位置均产生具有位置相同且扩散方向一致的衍射条纹，从而产生明显的衍射效应，使得位于该显示面板下方的感光元件无法正常工作。本实施例中的显示面板可以很好的解决该问题，确保显示面板下方的感光元件能够正常工作。
在一实施例中，基板110可以为玻璃基板、石英基板或者塑料基板等透明基板。
在一实施例中，第一类型像素开口在基板110上的投影的各边采用的曲线可以为圆形、椭圆形和其他具有变化曲率的曲线中的至少一种。
在一实施例中，第一类型像素开口在基板110上的投影为一个图形单元或者多个彼此连通的图形单元。该图形单元可以为圆形或者椭圆形。图形单元还可以由其他各处具有不同曲率半径的曲线构成。图形单元的个数可以根据对应的子像素的形状来确定。例如，可以根据子像素的长宽比来确定个数。在确定图形单元的个数的同时需要考虑像素的开口率。在一实施例中，图形单元还可以为轴对称结构，从而确保整个显示面板上的各像素具有一致的开 口率，不会影响最终的显示效果。
第一类型像素开口在基板110上的投影具有至少两个图形单元时，投影还包括第一连接部。至少两个图形单元通过第一连接部相互连通，形成整体连通的图形区域。第一连接部的各边可以由曲线和直线中的至少一种构成。当第一连接部的各边为直线时，第一连接部的形状为条状。在一实施例中，第一连接部的各边均由曲线构成，从而使得光线在连接单元位置处也能够产生不同方向的扩散，以减弱衍射效应。
图2为一实施例中的像素定义层120在基板110上的投影的示意图。在本实施例中，像素定义层120上的像素开口130均为第一像素类型开口。多个第一类型像素开口规则地阵列排布在基板110上。第一类型像素开口在基板110上的投影130a的各边均为曲线，即第一类型像素开口的各边为曲线。因此，当光线经过第一像素类型开口时，产生的衍射条纹不会只朝着一个方向扩散，从而使得衍射不明显，具有较佳的衍射改善效果。具体地，每个第一类型像素开口在基板110上的投影130a(以下简称投影130a)为一个圆形或者至少两个圆形彼此连通的图形。投影130a中所包含的圆形的数量可以根据对应的子像素的形状来确定。
参见图2，在本实施例中，第一类型像素开口130a对应的子像素形状为长宽比小于1.5的长方形或者正方形，也即，当第一类型像素开口130a对应的子像素形状的长宽比小于1.5时，投影130a为一个圆。在一实施例中，投影130a为轴对称图形，其对称轴与相应子像素的对称轴对应。投影130a中的圆的直径小于子像素的最小宽度。具体地，投影130a的圆的直径可以根据子像素的形状并结合开口率确定。投影130a的圆的直径的确定方法可以采用传统的确定像素开口的尺寸的方法，此处不赘述。
图3为另一实施例中的像素定义层120在基板110上的投影的示意图。在本实施例中，像素开口130同样均为第一类型像素开口，并且各第一类型像素开口规则排布在基板110上。在本实施例中，第一类型像素开口对应的像素的长宽比在1.5到2.5之间。此时，投影130a为由两个圆形彼此连通形 成的哑铃形。两个圆分别沿对应的子像素的长度方向排布。在一实施例中，两个圆之间有第一连接部1301，第一连接部1301的两边均为曲线，而确保光线经过第一连接部1301时，也能够向各个方向扩散，从而改善衍射效果。
图4为一实施例中的像素定义层120在基板110上的投影的示意图。在本实施例中，像素开口130同样均为第一类型像素开口，并且各第一类型像素开口规则排布在基板110上。在本实施例中，第一类型像素开口对应的子像素的长宽比大于2.5。此时，投影130a为由三个以上圆形彼此连通而成的波浪形。三个以上圆形分别沿对应的子像素的长度方向排布。在一实施例中，投影130a中还形成有第一连接部1302。第一连接部1302为弧线，也即三个以上圆形的相交处采用弧线连接，从而确保光线经过第一连接部1302时，也能够向各个方向扩散，从而改善衍射效果。
当第一类型像素开口对应的子像素的长宽比等于1.5时，投影130a可以为一个圆形，也可以为两个圆形彼此连通的哑铃形。当第一类型像素开口对应的子像素的长宽比等于2.5时，投影130a可以为两个圆形彼此连通的哑铃形，也可以为由三个圆形彼此连通的波浪形。
图5为一实施例中的像素定义层120在基板110上的投影的示意图。在本实施例中，像素开口130同样均为第一类型像素开口，并且各第一类型像素开口规则排布在基板110上。参见图5，投影130a为一个椭圆。此时，椭圆的尺寸与子像素的尺寸相匹配。例如，子像素的尺寸长宽比为1.2，则椭圆的长轴与短轴的比为1.2。在一实施例中，椭圆的中心点与对应子像素的中心点对应。在其他的实施例中，当第一类型像素开口对应的子像素的长宽比较大时，投影130a也可以为两个或者两个以上的椭圆连通的波浪形。
从图2至图5中可以清楚地看出，投影130a在各个方向上均具有变化的宽度，也即第一类型像素开口在各个方向上均具有变化的宽度，从而使得光线经过时会在不同宽度位置处产生具有不同位置的衍射条纹，从而减弱衍射效应。
在一实施例中，投影130a上形成有多个凸起130b，如图6所示。多个 凸起130b沿投影130a的边缘排布。凸起130b的边均为曲线。由于像素定义层120用于定义子像素的形状，故最终得到的子像素也具有多个凸起，且多个凸起沿子像素的边缘排布。通过在子像素上设置多个凸起130b，能够进一步打乱子像素各处的宽度的均匀性分布，从而降低衍射效应。
在一实施例中，像素开口130还可以包括第二类型像素开口，此时像素定义层120在基板110上的投影如图7所示。第二类型像素开口在基板110上的投影为130d，其具有与子像素相同的形状。在本实施例中，子像素的形状为正方形，故投影130d也为正方形，从而可以在一定程度提高像素开口率。投影130a和投影130d均规则排布在基板110上，且二者相间分布，也即第一类型像素开口和第二类型像素开口在均匀规则排布，从而使得整个显示面板在各处的衍射效果较为一致。
在一实施例中，像素定义层120中的各像素开口130包括第一类型像素开口和第二类型像素开口，第一类型像素开口和第二类型像素开口的各边均为非平滑边。非平滑边上形成有多个凸起；凸起的边为直线和/或曲线。通过将像素开口130的各边设置为非平滑边，能够进一步打乱像素开口各处的宽度的均匀性分布，从而降低衍射效应。
在一实施例中，显示面板还包括形成于发光区域的发光结构140。相邻两个发光结构140之间形成有像素定义层120。发光结构140包括形成于基板110上的波浪形的第一电极142。图8为多个第一电极142的示意图。此时，显示面板为被动矩阵有机发光二极体(Passive-Matrix Organic Light-Emitting Diode，PMOLED)显示面板。在本实施例中，由于第一电极142为波浪形，因此在第一电极142的延伸方向上，其宽度为连续变化或者间断变化。宽度连续变化是指第一电极142上任意两个相邻位置处的宽度不相同。图8中，第一电极142的延伸方向为其长度方向。第一电极142在延伸方向上宽度连续变化。而宽度间断变化是指在第一电极142上存在部分区域内相邻两个位置的宽度相同，而在部分区域内相邻两个位置的宽度不相同。在本实施例中，多个第一电极142在基板110上规则排布，因此，相邻两个 第一电极142之间的间隙在平行于第一电极142的延伸方向上也呈现为连续变化或者间断变化。第一电极142在延伸方向上，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。
在一实施例中，第一电极142在延伸方向上的两条边均为波浪形，如图8所示。延伸方向上的两条边的波峰T相对设置且波谷B相对设置。本实施例中，两条边均由同一圆弧形边相连而成。在其他的实施例中，两条边也可以均由同一椭圆形边相连而成，如图9所示。通过将第一电极142的两边设置成由圆弧形或者椭圆形形成的波浪形，可以确保第一电极142上产生的衍射条纹能够向不同方向扩散，进而避免产生较为明显的衍射效应。
在一实施例中，在第一电极142的波谷相对处形成有第二连接部1422，如图10所示。第二连接部1422为条状。第二连接部1422的宽度W应该大于4微米，且小于第一电极142上的最大宽度。在一实施例中，第一电极142上相邻两个第二连接部1422之间的区域对应一个像素开口，第二连接部1422则对应于相邻两个像素开口之间的间隙。通过对第二连接部1422的宽度W的调整，可以实现对第一电极142上的电阻大小的调整，以使得其满足使用需求。在其他的实施例中，第二连接部1422也可以采用其他不规则结构，如中间小两端大的形状，或者采用中间大两端小的形状。
在另一实施例中，第一电极142上形成有多个凸起142a，如图11所示。多个凸起142a的边为曲线。通过在第一电极142上设置多个142a，能够进一步打乱第一电极120各处的宽度的均匀性分布，从而降低衍射效应。
在其他的实施例中，发光结构140还包括形成于第一电极142上的发光层144以及第二电极146，如图1所示。其中，第一电极142为阳极，第二电极146为阴极。在其他的实施例中，第一电极142为阴极，第二电极146为阳极。第二电极146与第一电极142的延伸方向相互垂直。第二电极146可以与第一电极142的形状相同，均采用波浪形的电极结构。
在一实施例中，第一电极142在基板110上的投影的边与像素开口130 在基板110上的投影的边互不平行。如图12所示，在不同位置，两者在对应区域的间距AA不相同，从而使得具有不同间距的位置产生的衍射条纹也具有不同的位置，最终可以弱化衍射效应，进而确保摄像头设置在该透明显示面板下方时，拍照得到的图形具有较高的清晰度。
在一实施例中，显示面板为主动矩阵有机发光二极体(Active-Matrix Organic Light-Emitting Diode，AMOLED)显示面板。此时，基板110为薄膜晶体管(Thin Film Transistor，TFT)阵列基板。基板110上形成有第一电极。第一电极包括形成于TFT阵列基板上的各类导电走线。第一电极的宽度尺寸需要根据导电走线的宽度来设计。其中，导电走线包括扫描线、数据线以及功率线中的至少一种。例如，可以将TFT阵列基板上的所有导电走线如扫描线、数据线以及功率线进行改进，采用如图8所示的电极形状。通过将TFT阵列基板上的导电走线改成图8至图11中的任意一种波浪形的电极形状，可以确保在导线走线的延伸方向上，光线经过在不同宽度位置处以及相邻走线的不同间隙处时能够形成具有不同位置的衍射条纹，进而减弱衍射效应，使得放置于其下方的感光器件能够正常工作。
在一实施例中，在显示面板为AMOLED显示面板时，显示面板还包括形成于基板上方的阳极层。阳极层包括阳极阵列。阳极阵列由多个相互独立的阳极构成。阳极的形状可以为圆形、椭圆形或者由彼此连通的两个圆形形成的哑铃形。图13为采用圆形的阳极形成的阳极阵列的示意图，图14为哑铃形的阳极形成的阳极阵列的示意图。通过将阳极形状改为圆形、椭圆形或者哑铃形，可以确保光线经过阳极层时，在阳极的不同宽度位置处同样能够产生具有不同位置以及扩散方向的衍射条纹，从而弱化衍射效应。进一步的，各个子像素也可设置为图13和图14所示的圆形、椭圆形或者哑铃形，以弱化衍射效应。
在一实施例中，阳极在基板110上的投影的边与像素开口130在基板110上的投影的边互不平行。如图15所示，在不同位置，二者对应区域的间距AA不相同，从而使得具有不同间距的位置区域产生的衍射条纹也具有不同的 位置，不同位置处的衍射相互抵消，最终可以弱化衍射效应，进而确保摄像头设置在该透明显示面板下方时，拍照得到的图形具有较高的清晰度。
在一实施例中，上述显示面板还可以为LCD显示面板。
在一实施例中，上述显示面板可以为透明的或者半透半反式的显示面板。显示面板的透明可以通过采用透光率较好的各层材料来实现。例如，各层均采用透光率大于90％的材料，从而使得整个显示面板的透光率可以在70％以上。可选的，各层均采用透光率大于95％的材料，从而使得整个显示面板的透光率在80％以上。具体地，导电走线如阴极和阳极等的材料可以为ITO、IZO、Ag+ITO或者Ag+IZO等，绝缘层材料优选SiO 2，SiN x以及Al 2O 3等，像素定义层120的材料则采用高透明材料。显示面板的透明还可以采用其他技术手段实现，上述显示面板的结构均可以适用。透明或者半透半反式的显示面板处于工作状态时能够正常显示，而在不工作时处于不显示状态。当显示面板处于不显示状态时，其面板呈现透明或者半透明的状态。此时可以透过该显示面板看到放置于该显示面板之下的感光器件等。
本申请一实施例还提供一种显示屏。该显示屏具有第一显示区，第一显示区用于显示动态或静态画面。第一显示区设置有如前述任一实施例中所提及的显示面板。第一显示区下方可以设置感光器件。由于第一显示区采用了前述实施例中的显示面板，因此当光线经过该显示区域时，不会产生较为明显的衍射效应，从而能够确保位于该第一显示区下方的感光器件能够正常工作。在感光器件不工作时，第一显示区随着整体显示屏的显示内容的变化而变化，如显示正在拍摄的外部图像；或者第一显示区也可以处于不显示状态，从而进一步确保感光器件能够透过该显示面板正常进行光线采集。
图16为一实施例中的显示屏的示意图。该显示屏包括第一显示区910和第二显示区920，第二显示区920与第一显示区910相邻。第一显示区910的透光率大于第二显示区920的透光率。第一显示区910的下方可设置感光器件930。第一显示区910设置有如前述任一实施例中所提及的显示面板。第一显示区910和第二显示区920均用于显示静态或者动态画面。由于第一 显示区910采用了前述实施例中的显示面板，因此当光线经过该显示区域时，不会产生较为明显的衍射效应，从而能够确保位于该第一显示区910下方的感光器件930能够正常工作。第一显示区910在感光器件930不工作时，可以正常进行动态或者静态画面显示，而在感光器件930工作时，可以处于不显示状态，从而确保感光器件930能够透过该显示面板正常进行光线采集。在其他的实施例中，第一显示区910和第二显示区920的透光率也可以相同，从而使得整个显示面板具有较好的透光均一性，确保显示面板具有较好的显示效果。
在一实施例中，设置在第一显示区910的显示面板为PMOLED显示面板或AMOLED显示面板，设置在第二显示区920的显示面板为AMOLED显示面板，从而可以形成由PMOLED显示面板和AMOLED显示面板构成的全面屏。
本申请另一实施例还提供一种显示终端。图17为一实施例中的显示终端的示意图，该显示终端包括设备本体810和显示屏820。显示屏820设置在设备本体810上，且与该设备本体810相互连接。其中，显示屏820可以采用前述任一实施例中的显示屏，用以显示静态或者动态画面。
图18为一实施例中的设备本体810的示意图。在本实施例中，设备本体810上可设有开槽区812和非开槽区814。在开槽区812中可设置有诸如摄像头930以及光传感器等感光器件。此时，显示屏820的第一显示区的显示面板贴合在开槽区814，以使得上述的诸如摄像头930及光传感器等感光器件能够透过该第一显示区对外部光线进行采集等操作。第一显示区中的显示面板能够有效改善外部光线透射该第一显示区所产生的衍射现象，从而可有效提升显示设备上摄像头930所拍摄图像的质量，避免因衍射而导致所拍摄的图像失真，同时也能提升光传感器感测外部光线的精准度和敏感度。
上述电子设备可以为手机、平板、掌上电脑、ipod等数码设备。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本申请专利范围的限制。对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
