Description

一种显示面板及其显示装置
本申请要求于2019年12月12日提交中国专利局、申请号为201911274082.8、发明名称为“一种显示面板及其显示装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。

本发明涉及显示技术领域，具体涉及一种显示面板及其显示装置。
 背景技术
显示装置可以把计算机的数据变换成各种文字、数字、符号或直观的图像显示出来，并且可以利用键盘等输入工具把命令或数据输入计算机，借助系统的硬件和软件随时增添、删改、变换显示内容。显示装置根据所用之显示器件分为等离子、液晶、发光二极管和阴极射线管等类型。
有机发光显示装置(英文全称：Organic Light-Emitting Diode, 简称OLED)又称为有机电激光显示装置、有机发光半导体。OLED的工作原理是：当电力供应至适当电压时，正极空穴与阴极电荷就会在发光层中结合，在库伦力的作用下以一定几率复合形成处于激发态的激子（电子-空穴对），而此激发态在通常的环境中是不稳定的，激发态的激子复合并将能量传递给发光材料，使其从基态能级跃迁为激发态，激发态能量通过辐射驰豫过程产生光子，释放出光能，产生光亮，依其配方不同产生红、绿和蓝RGB三基色，构成基本色彩。
OLED具有电压需求低、省电效率高、反应快、重量轻、厚度薄，构造简单，成本低、广视角、几乎无穷高的对比度、较低耗电、极高反应速度等优点，已经成为当今最重要的显示技术之一。

其中所述显示面板100还包括像素单元1，所述像素单元1分布于所述显示区101的所述显示面板100上。
如图2所示，所述主显示区1011的所述像素单元1相互连接呈阵列排布。其中所述像素单元1均包括四个子像素，所述四个子像素分别为一个红色子像素11、一个蓝色子像素13和两个绿色子像素12。
如图3所示，所述摄像区1012的所述显示面板100包括像素单元1，还包括至少一透光孔2，所述透光孔2设置于所述摄像区1012未设置像素单元1的区域。其中所述像素单元1均包括四个子像素，所述四个子像素分别为一个红色子像素11、一个蓝色子像素13和两个绿色子像素12。通过去除摄像区1012中的部分摄像单元1形成透光孔2，便于外部光线能够经过透光孔2直接射入后期对应于所述摄像区1012的显示面板100下方设置的摄像元件200，从而达到拍摄目的。由于所述摄像区1012去除了部分像素单元1，因此所述摄像区1012的显示面板100未被去除的摄像单元1还是可以正常显示的，因此在解决摄像元件200透光性的问题的同时可以实现全面屏，提高了显示面板100的屏占比。
如图2、图3所示，其中所述摄像区1012的所述像素单元1的分布密度小于所述主显示区1011的所述像素单元1的分布密度。具体的，其中所述摄像区1012的所述像素单元1的分布密度小于或等于所述主显示区1011的所述像素单元1的分布密度的二分之一。换句话讲，可以在所述摄像区1012隔一个像素单元1设置一个透光孔2。
其中所述主显示区1011的所述像素单元1是均匀排列的。由此主要是为了防止摄像单元1分布不均匀造成的显示差异，避免导致客户使用体验感差。
其中所述摄像区1012的所述像素单元1是均匀排列的。由此主要是为了防止摄像单元1分布不均匀造成的显示差异，避免导致客户使用体验感差。另一方面，由于摄像区1012去除了部分像素单元1形成透光孔，会导致单位面积内像素单元的数量的减少，客户在使用时会感觉到去除像素单元1和未去除像素单元1之间的差异，因此尽可能的将像素单元1均匀分布，可以使摄像区1012的显示面板100显示更均匀。
如图1所示，为了通过多个摄像元件200共同拍摄图片，对画质进行补正，使照片进行优化，提高摄像的拍照范围，我们需要增加摄像元件200的数量，因此需要增加摄像区1012的数量。因此，其中所述显示区101可以包括两个或者三个摄像区1012，每一摄像区1012具有至少一透光孔2。本实施例的所述显示区101包括了2个摄像区1012。
如图1所示，由于透光孔2的形成会导致单位面积内像素单元1的数量的减少，因此会导致画面显示的细致度的降低。客户在使用时会感觉到去除像素单元1和未去除像素单元1之间的差异，影响客户体验感。由于客户使用时，精力比较集中于中心为孩子，对于角落处的关注比较少，因此我们将摄像区1012设置于显示面板100的左上角和右上角，以此可以避免客户感知到透光孔2的设置带来的画面差异感。
如图1所示，其中所述摄像区1012的形状包括矩形、多边形、圆形、椭圆形中的一种或多种。本实施例中所述摄像区1012的形状为矩形。
如图4所示，所述像素单元1包括：基板3、薄膜晶体管结构层4、像素定义层5、像素电极6、发光层7以及阴极层8。其中所述薄膜晶体管结构层4设置于所述基板3上；所述像素定义层5设于薄膜晶体管结构层4上，所述像素定义层5具有一开口；所述像素电极6设置于所述像素定义层5的开口中；所述发光层7设置于所述开口中的所述像素电极6上；所述阴极层8设置于所述发光层7上。
当电力供应至适当电压时，像素电极6中的空穴与阴极层8中的电荷就会在发光层7中结合，在库伦力的作用下以一定几率复合形成处于激发态的激子（电子-空穴对），而此激发态在通常的环境中是不稳定的，激发态的激子复合并将能量传递给发光层7中的发光材料，使其从基态能级跃迁为激发态，激发态能量通过辐射驰豫过程产生光子，释放出光能，产生光亮。
其中所述薄膜晶体管结构层4包括缓冲层、有源层、栅极层、栅极绝缘层、源漏极层、层间绝缘层、平坦层等结构，此不赘述。
如图4所示，其中所述透光孔2由所述阴极层8远离所述基板3的表面贯穿至所述基板3远离所述阴极层8的表面。事实上，所述透光孔2还可以自像素电极6远离所述基板3的表面向下贯穿至所述基板3远离所述阴极层8的表面。本实施例的设计可以避免发光层7以及阴极层8的设置影响光线进入摄像元件200，提高透光效果，另一方面也是避免发光层7以及阴极层8的材料浪费，降低生产成本。
如图5所示，其中所述显示面板100还包括：第一无机层9、有机层10、第二无机层11。其中所述第一无机层9设置于所述阴极层8上；所述有机层10设置于所述第一无机层9上；所述第二无机层11设置于所述有机层10上。
其中所述第一无机层9和第二无机层11主要起阻水氧作用，防止水氧入侵导致显示面板100中的元件的损坏，提高产品使用寿命。
其中所述有机层10主要是起缓冲作用，对显示装置使用时收到的应力达到释放效果，避免显示装置受外界应力作用时损坏。
如图5所示，本发明还提供了一种显示装置，其中包括本发明所涉及的显示面板100，还包括摄像元件200，所述摄像元件200对应设置于所述摄像区1012的显示面板100下方。
本发明还提供一种移动终端，所述移动终端包括上述显示装置。其中所述移动终端包括平板电脑、笔记本电脑中的一种或多种。其中所述移动终端一般会有显示电量、显示网络信号、显示时间的图标，一般客户使用时很少会注意这些图标，因此我们可以将摄像区1012设置于这些图标对应的位置，同样的可以避免客户感知到透光孔2的设置带来的画面差异感。
实施例2
如图6所示，本实施例与实施例1的区别在于：其中所述显示区101包括四个摄像区1012，每一摄像区1012具有至少一透光孔2。所述摄像区1012设置于所述显示面板100的四个角落，由此可以避免客户感知到透光孔2的设置带来的画面差异感。
以上对本发明所提供的显示面板及其显示装置进行了详细介绍。应理解，本文所述的示例性实施方式应仅被认为是描述性的，用于帮助理解本发明的方法及其核心思想，而并不用于限制本发明。在每个示例性实施方式中对特征或方面的描述通常应被视作适用于其他示例性实施例中的类似特征或方面。尽管参考示例性实施例描述了本发明，但可建议所属领域的技术人员进行各种变化和更改。本发明意图涵盖所附权利要求书的范围内的这些变化和更改，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
