Description

显示面板、显示屏及电子设备 技术领域
本公开涉及显示技术领域，尤其涉及一种显示面板、显示屏及电子设备。
背景技术
屏下成像是未来最近几年显示屏行业最有前途的方向和研究热点。但是目前存在显示屏整体成像画质的影响大，解析力和对比度都大幅降低等问题。通过分析画质下降的原因，发现实际的画质下降比理论上衍射引起的画质下降程度更大。细分原因屏对整体画质下降的影响因素分为三点，透过率下降，衍射作用和散射影响。目前的方案主要关注降低衍射的影响，但通过理论分析，模拟和实验验证发现散射对画质的影响更大，而显示屏在有效成像视场角范围内，因金属电路层叠或其他不透光材料等因素会使入射光发生反射或散射，导致其出射光角度改变，进入成像组件后中形成杂散光，对有效成像造成干扰，降低了成像质量。
发明内容
有鉴于此，本公开提出了一种能同时实现良好显示与光学成像功能的显示面板、显示屏及电子设备以解决上述部分或全部技术问题。
为了达到上述目的，本公开所采用的技术方案为：
根据本公开实施例的第一方面，提供了一种显示面板，包括显示单元和透光显示单元，所述显示单元包括：基板以及设置于所述基板上的至 少一个像素，所述像素包括多个子像素，相邻两个所述子像素之间构成透光间隙；所述子像素包括位于所述基板上的金属电路层、位于所述金属电路层上的第一电极层、位于所述第一电极层上的发光层以及位于所述发光层上的第二电极层；其中，所述第一电极层为非透明阳极，所述显示单元还包括至少遮挡所述透光间隙的遮光层。
根据本公开实施例的第二方面，提供了一种显示屏，包括：主显示区域和副显示区域；其中，所述副显示区域通过上述中任一项所述的显示面板制成。
根据本公开实施例的第三方面，提供了一种电子设备，包括设备本体、设置于所述设备本体上的成像组件以及如上述的显示屏；其中，所述显示屏装配于所述设备本体，所述成像组件对应设置于所述显示屏的副显示区域。
本公开的实施例提供的技术方案可以包括以下有益效果：本公开通过在显示面板的显示单元中增设遮光层，通过完全遮光以减少显示单元中的杂射光进入成像组件，从而减少对有效成像的干扰，以使屏下成像组件的成像质量得到最无损的呈现，进而为显示面板的显示分辨率和显示面板与成像组件结合的成像画质提供一个最优的平衡方案。
应当理解的是，以上的一般描述和后文的细节描述仅是示例性和解释性的，并不能限制本公开。

为了更清楚地说明本公开实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本公开的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
下面将结合本公开实施例中的附图，对本公开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。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
在本公开使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开。在本公开和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
下面结合附图，对本公开的一些实施方式作详细说明，在不冲突的情况下，下述的实施例及实施例中的特征可以相互组合。
如图1所示，本公开实施例的显示面板10包括显示单元11和透光显示单元12。该显示单元11包括基板1以及设置于基板1上的至少一个 像素111，在具有多个像素111时，多个像素111可以以矩阵或者任意形状的方式设置在基板1上，相邻像素111之间构成透光区域。该像素111包括若干子像素1111，子像素1111也可以以矩阵或者任意形状的方式进行排布，该每个子像素1111所发出的光为红(R)、绿(G)、蓝(B)三原色中的一种，如此多个子像素1111通过三原色的配合可以使像素111发出各种颜色的光。其中，发出RGB的子像素1111可以以任意配色方式进行排布，图示中RGB的排布仅为示意性展示。
该子像素1111包括位于基板1上的金属电路层2、位于金属电路层2上的第一电极层3、位于第一电极层3上的发光层4以及位于发光层4上的第二电极层5。其中，当电力供应至适当电压时，金属电路层2驱动第一电极层3与第二电极层5中的电荷在发光层4结合，从而使发光层4产生光亮。
本公开的实施例中，基板1可以是刚性衬底，如玻璃衬底、石英衬底或者塑料衬底等透明基板。基板1也可为柔性透明衬底，如聚酰亚胺(Polyimide，PI)薄膜等，以提高器件的透明度。该第一电极层3为非透明阳极层，第二电极层5为阴极层。
相邻两个子像素1111之间构成透光间隙6，由于子像素1111呈矩阵或者任意形状排布，因此每个子像素1111的周围具有多个透光间隙6。现有技术中，入射光在部分透光间隙6中会与层叠的金属电路层2或者其他不透光材料发生散射或反射，如此以导致出射光偏离入射光方向，出射光在成像面汇聚时形成杂散光，以使显示面板10降低成像质量。
针对上述技术问题，本公开的显示单元11还包括至少遮挡透光间隙6的遮光层7，该透光间隙6具有反射光线或者散射光线射出。本公开通过遮光层7的设置可以有效减少散射或者散射引起的成像画质损失，提升显示面板10的解析力。
在遮光层7的作用下(即通过遮光层7消除各个子像素1111的金属电路层2所产生的反射光和散射光)，该显示面板10的雾度小于20％。优选地，在该遮光层7的作用下以使显示面板的10雾度低于15％。其中，需要说明的是，遮光层7的增加会降低入射光通过显示面板的整体透过率，但对成像画质的影响较小。
本公开的透光单元12的结构有多种可能性，比如可以是透光单元12中没有金属电路层和第一电极层等遮光元件，只保留发光层4和第二电极层5等透光或半透明元件。另一种可以是工艺允许的情况下去除金属电路层、第一电极层、发光层和第二电极层。又或者可以在金属电路层改用透明材料，与显示单元11结构相同，实现既可成像又可显示功能。本公开中对透光单元12的位置和尺寸没有指定，对透光单元12的形状和排列方式没有限制，该透光单元12可以是圆形或者方形或者无规则形状，该透光单元12的排列可以是阵列式排布或者错位或者不规则分布。
本公开对遮光层7的位置设定也并不限定，该遮光层7的目的是为了减少散射光或反射光对显示面板10下成像组件的成像影响，下列各个实施例对遮光层7的具体设置位置进行限定。
在第一实施例中，如图1所示，该遮光层7设置于基板1与金属电路层2之间且覆盖于像素111中每个子像素1111的金属电路层2。该实施例中，该遮光层7贴合于整个显示单元11，具体地贴于每个子像素1111的金属电路层2，从而消除各个子像素1111的金属电路层2所产生的反射光和散射光，减少反射光和散射光对屏下成像组件引起的画质损失。
在第二实施例中，如图2所示，遮光层7设置于基板1与金属电路层2之间，该遮光层7为多个且分别对应遮挡显示单元11中的各个透光间隙6。由于第一电极层3是非透明阳极，因此金属电路层2的发射光和散射光是通过透光间隙6射出的，该实施例通过将遮光层7设置于基板1与金属电路层2之间而遮挡于透光间隙6，即设置于反射光和散射光的传播 路径上，以使遮光层7可以消除透光间隙6内的反射光和散射光，减少反射光和散射光对屏下成像组件引起的画质损失。
在第三实施例中，如图3所示，遮光层7设置于金属电路层2与第一电极层3之间，遮光层7为多个且分别对应遮挡显示单元11中的各个透光间隙6。由于第一电极层3是非透明阳极，因此金属电路层2的发射光和散射光是通过透光间隙6射出的，该实施例通过将遮光层7设置于金属电路层2与第一电极层3之间而遮挡于透光间隙6，即该遮光层7设置于反射光和散射光的传播路径上，以使遮光层7可以消除透光间隙6内的反射光和散射光，减少反射光和散射光对屏下成像组件引起的画质损失。其中，该遮光层7的设置需要满足保证金属电路层2与第一电极层3之间的电性连接。
在第四实施例中，如图4所示，遮光层7连接于相邻两个子像素1111中第一电极层3之间，遮光层7为多个且分别对应遮挡显示单元11中的各个透光间隙6。该实施例中，该遮光层7通过连接于第一电极层3的侧面以将透光间隙6遮挡住，通过与非透明的第一电极层3的配合从而可以避免入射光照射到金属电路层2而形成反射光和散射光。该遮光层7可以消除透光间隙6内的反射光和散射光，减少反射光和散射光对屏下成像组件引起的画质损失。
在上述各个实施例中，该遮光层7的材料不受限制，只要满足可以遮光的效果即可。具体地该遮光层7可以为遮光金属层或者黑胶层，在遮光层7为金属时，可以为铝、钛或者铜等金属。
在另一实施例中，如图5所示，该遮光层7还可以为设置于子像素1111中第一电极层3外围的扩展电极块，该扩展电极块为多个且分别对应遮挡于显示单元11中的各个透光间隙6。该实施例中，通过扩展电极块以将透光间隙6遮挡住，该扩展电极块与第一电极层3一体成型制成，该扩展电极块与第一电极层3均为非透明阳极。简单来说，即通过增加第一电 极层3的尺寸以消除该透光间隙6，从而消除透光间隙6内的反射光和散射光，减少反射光和散射光对屏下成像组件引起的画质损失。
此外，为了进一步地增加显示面板10的透光效果，该显示面板10中各个透光显示区域12可以使用透明电路，该显示面板10可以无需设置偏光层等方式，可以进一步地提高成像组件的画质。
本公开通过在显示面板的显示单元中增设遮光层，通过完全遮光以减少显示单元中的杂射光进入成像组件，从而减少对有效成像的干扰，以使屏下成像组件的成像质量得到最无损的呈现，进而为显示面板的显示分辨率和显示面板与成像组件结合的成像画质提供一个最优的平衡方案。
如图6结合图1所示，根据本公开实施例的又一方面，还提供了一种显示屏100，该显示屏100与光学成像系统结合能同时实现良好显示与成像功能。该显示屏100包括主显示区域101和副显示区域102。其中，副显示区域102通过上述各个实施例的显示面板10制成。该副显示区域102可以同时实现显示和成像。该副显示区域102可以根据应用需求设置于显示屏100的任一位置。
本公开的主显示区域101主要用于画面显示，该主显示区域101由基板1、金属电路层2、第一电极层3、发光层4及第二电极层5依序层叠组成。该主显示区域101与副显示区域102的结构层相同，区别在于：副显示区域102进行了透光设计。本公开的副显示区域102中的显示面板10可以通过降低像素密度，第一电极层3和第二电极层5采用透明材料，以及改变金属电路层2的结构设计等方式，以满足显示单元11具有透光效果。
进一步地，该副显示区域102中相邻两个像素111之间的间距变大，如此以增加副显示区域102的透光区域，从而使副显示区域102具有透光效果。
为了进一步提高显示面板10对应成像组件的成像画质，本公开的显 示面板10还包括遮挡目标透光间隙6的遮光层7，该目标透光间隙6为具有反射光线或者散射光线射出的透光间隙6。本公开通过遮光层7的设置可以有效减少散射或者散射引起的成像画质损失，提升显示面板10的解析力。该遮光层7的具体设置位置及材料可参见上述显示面板10的各个实施例，在此不再赘述。
需要说明的是，在一种可选的实施例中，显示屏100也可以只设置副显示区域102，该副显示区域102通过上述各个实施例的显示面板10制成。
如图7所示，根据本公开实施例的另一方面，还提供了一种电子设备200，该电子设备200包括设备本体201、设置于设备本体201上的成像组件202以及如上述各个实施例所述的显示屏100。其中，显示屏100装配于设备本体201，成像组件202对应设置于显示屏100的副显示区域102，如此即实现了屏下成像组件202的设置。从而可以满足电子设备200的全面屏显示。
其中，本公开的电子设备200可以是任一具备显示屏的设备，例如，移动通信终端(如手机)、PDA(Personal Digital Assistant，掌上电脑)、移动电脑、平板电脑、可穿戴设备等设备。
本公开的显示屏100上包括副显示区域102，该副显示区域102在保证正常显示的前提下，还可以使成像组件202透过该副显示区域102进行拍摄，且不影响成像组件202的拍摄效果。
优选地，该副显示区域102的尺寸与成像组件202相匹配，如此以尽可能地减小该副显示区域102的尺寸，以减小成像组件202进行拍摄时显示屏100未显示的区域尺寸，从而可以提高用户使用过程中的视觉感受。
本领域技术人员在考虑说明书及实践这里公开的公开后，将容易想到本公开的其它实施方案。本申请旨在涵盖本公开的任何变型、用途或者 适应性变化，这些变型、用途或者适应性变化遵循本公开的一般性原理并包括本公开未公开的本技术领域中的公知常识或惯用技术手段。说明书和实施例仅被视为示例性的，本公开的真正范围和精神由本申请的权利要求指出。
应当理解的是，本公开并不局限于上面已经描述并在附图中示出的精确结构，并且可以在不脱离其范围进行各种修改和改变。本公开的范围仅由所附的权利要求来限制。
