Description

一种显示面板及显示装置 技术领域
本发明涉及显示领域，尤其涉及一种显示面板及显示装置。
 背景技术
随着智能手机朝着全面屏的方向快速发展，屏占比要求越来越高，目前出现如iPhone X的刘海屏（Notch）设计方案，仅仅在手机的“前额”预留空间给前置摄像头，其余地方均为显示区域。
在屏内采用圆形开孔设计，在相机的位置开个圆形孔，从而使智能手机的“前额”进一步变窄，比刘海屏更接近全面屏，实现更大的屏占比。
为了进一步提高屏占比，同时不破坏显示的完整性，因此不允许在显示屏显示有效区内进行刘海屏或者开孔设计；因此人们想到将摄像头设置在屏幕下方，摄像头上方仍然可以正常显示，同时可以进行拍照，即我们目前所讲的屏下摄像头技术。
但是基于目前有机发光二极管（OLED）面板的结构，而且由于阵列基板为多层、密集的不规则金属线路，这些不透明的金属线路导致有机发光二极管面板实际透过率非常低，而且细小金属线路间存在狭缝衍射导致存在很多杂散光，严重影响屏下摄像头的成像质量。具体的，传统的有机发光二极管（OLED）显示屏，其驱动晶体管（TFT）位于其驱动的发光像素单元（Pixel）的正下方，由于驱动晶体管包含了有源层、栅极层、源漏极层等多层叠加的金属线路，这些不透明的金属线路导致有机发光二极管显示屏实际透过率非常低，而且细小金属线路间存在狭缝衍射导致存在很多杂散光，严重影响屏下摄像头的成像质量。

如图1所示，本实施例中，所述第二发光像素单元3包括至少一红色子像素31、至少一绿色子像素32和至少一蓝色子像素33，呈阵列式排布于所述屏下摄像头区20内；一条所述导电走线4与至少一个所述红色子像素31电性连接；和/或，一条所述导电走线4与至少一个所述绿色子像素32电性连接；和/或，一条所述导电走线4与至少一个所述蓝色子像素33电性连接。这样，所述导电走线4呈直线形、波浪线形、弧线形或S线形。
其中，所述第二发光像素单元3的子像素在所述屏下摄像头区20间隔设置呈阵列排布，优选呈菱形设置，即所述凹槽也呈菱形设置。所述绿色子像素32的面积小于所述蓝色子像素33的面积，所述红色子像素31的面积介于所述绿色子像素32的面积和所述蓝色子像素33的面积之间。
特别的，位于所述屏下摄像头区20外围的所述晶体管单元1通过导电走线4连接至所述屏下摄像头区20内的所述第二发光像素单元3对应的阳极层301时，通常由于需要连接的子像素较多，同时走线空间有限，需要多层导电走线4上下层走线的方式进行。

本实施例中，所述导电走线4和/或所述源漏极层108的材质为氧化铟锡。氧化铟锡为透明材质，透过率在90%以上，可提高透光率，从而提高穿过所述屏下摄像头区20的光强。
本实施例中，所述晶体管单元1还包括：第二平坦层110，设于所述导电走线4上并设有走线过孔；所述导电走线4穿过所述走线过孔与所述第二发光像素单元3电性连接。特别的，所述第二发光像素单元3的位置与外围的所述晶体管单元1的位置的距离尽可能短，这样可以进一步减小所述导电走线4的交错，进一步减少对屏下摄像头光线的遮挡。
本实施例中，所述晶体管单元1还包括：像素定义层111，设于所述第二平坦层110上，并在对应所述导电走线4位置设有凹槽，即像素定义槽，所述第一发光像素单元2、所述第二发光像素单元3设于所述凹槽内。

本实施例中，所述第二发光像素单元3包括阳极层301、发光层302以及阴极层303；所述阳极层301与所述导电走线4电性连接；所述发光层302设于所述阳极层301上；所述阴极层303设于所述发光层302上。
请参阅图4所示，本实施例中，一个所述晶体管单元1通过一条所述导电走线4与位于同一排的多个所述红色子像素31电性连接；一个所述晶体管单元1通过一条所述导电走线4与位于同一排的多个所述蓝色子像素33电性连接。
本实施例中，位于同一排的所述红色子像素31与所述蓝色子像素33交替间隔设置，连接多个所述红色子像素31的一条导电走线4与连接多个所述蓝色子像素33的另一条导电走线4分别位于该排子像素的两侧。

本实施例中，一个所述晶体管单元1通过一条所述导电走线4与环绕一个所述红色子像素31或所述蓝色子像素33的四个所述绿色子像素32电性连接。
更具体的讲，请参阅图4所示，其中的一个外围的所述晶体管单元1去驱动一个以上的多个所述第二发光像素单元3发光，具体在图4中一条所述导电走线4与4个所述绿色子像素32电性连接，即一个对应绿色的所述晶体管单元1对应驱动4个所述绿色子像素32；一条所述导电走线4与2个所述红色子像素31电性连接，即一个对应红色的所述晶体管单元1对应驱动2个所述红色子像素31；一条所述导电走线4与2个所述蓝色子像素33电性连接，即一个对应蓝色的所述晶体管单元1对应驱动2个所述蓝色子像素33。亦即在图4中是同颜色的子像素之间先串联，然后与一个对应的所述晶体管单元1连接。
本实施例中，不同颜色的子像素对应的阳极层301通过内部导电走线4或者外部导电走线4电性串接在一起，提高了所述屏下摄像头区20的透光率，从而提高了穿过所述屏下摄像头区20的光强，增强了所述屏下摄像头区20屏下摄像头的感光能力，减少金属狭缝的衍射光的影响。
实施例2
请参阅图5所示，在实施例2中包括实施例1中大部分的技术特征，其区别在于，实施例2中的一个外围的所述晶体管单元1去驱动一个以上的多个所述第二发光像素单元3发光时多个同颜色的子像素同时与一个对应的所述晶体管单元1连接，而不是实施例1中同颜色的子像素之间先串联，然后与一个对应的所述晶体管单元1连接。
本实施例中，一个所述晶体管单元1通过一条所述导电走线4与位于同一排的多个所述红色子像素31电性连接；一个所述晶体管单元1通过一条所述导电走线4与位于同一排的多个所述蓝色子像素33电性连接。位于同一排的所述红色子像素31与所述蓝色子像素33交替间隔设置，连接多个所述红色子像素31的一条导电走线4与连接多个所述蓝色子像素33的另一条导电走线4分别位于该排子像素的两侧。一个所述晶体管单元1通过一条所述导电走线4与位于同一排的相邻两个所述红色子像素31电性连接；一个所述晶体管单元1通过一条所述导电走线4与位于同一排的相邻两个所述蓝色子像素33电性连接。一个所述晶体管单元1通过一条所述导电走线4与位于同一排的多个所述绿色子像素33电性连接，一条所述导电走线4的所述绿色子像素33的数量优选为四个。
本实施例通过导电走线4内部导线连接可以有效减少多层导电走线4上下层走线的层数，从而有效降低制程复杂度，降低成本。
具体如图5所示，其中的一个外围的所述晶体管单元1去驱动一个以上的多个所述第二发光像素单元3发光时，一条所述导电走线4与4个所述绿色子像素32电性连接，即一个对应绿色的所述晶体管单元1对应驱动4个所述绿色子像素32；一条所述导电走线4与2个所述红色子像素31电性连接，即一个对应红色的所述晶体管单元1对应驱动2个所述红色子像素31；一条所述导电走线4与2个所述蓝色子像素33电性连接，即一个对应蓝色的所述晶体管单元1对应驱动2个所述蓝色子像素33。在图5中是多个同颜色的子像素同时与一个对应的所述晶体管单元1连接，这样可实现所述导电走线4在一层走线内设连接多个同颜色的子像素，且用于连接不同颜色的子像素的所述导电走线4也可设置在不同层内。
请参阅图6所示，本发明还提供一种显示装置200，包括上文所述显示面板100以及传感器30，其中，所述传感器30对应所述屏下摄像头区20的位置设置。
本实施例中，所述传感器30包括摄像头传感器、呼吸灯传感器、距离传感器、指纹扫描仪传感器、麦克风传感器或透明天线传感器中的一种或其组合。
本发明的显示装置200可适用于各种场合，可与各种器件、结构相结合，显示装置200既可以是移动终端（手机、智能穿戴）或者固定终端（PC），也可为带有显示功能的其他设备，例如平板电脑、电视机、显示橱窗等。应该理解，为了实现功能，本发明的显示装置200带有在本说明书中未示出的其他器件、结构等。
本发明的有益效果在于，提供一种显示面板及显示装置，通过将位于屏下摄像头区外围的晶体管单元驱动一个以上的多个第二发光像素单元，不同颜色的子像素对应的阳极层通过内部导电走线或者外部导电走线电性串接在一起，提高了所述屏下摄像头区的透光率，从而提高了穿过所述屏下摄像头区的光强，增强了所述屏下摄像头区屏下摄像头的感光能力，减少金属狭缝的衍射光的影响。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
