技术领域
本申请实施例涉及显示技术领域，特别涉及一种显示面板及显示装置。
背景技术
显示屏具有透过率不同的区域，摄像头通过安装在透过率较高的区域，以确保摄像头的拍摄性能，但透过率较高的区域内会设置像素电路，使得该区域的透过率受到影响，从而导致显示面板的拍摄效果不佳。因此，有必要提供一种新的显示面板及显示装置来解决上述问题。
申请内容
本申请部分实施例的目的在于提供一种显示面板及显示装置，其能够提高显示面板的拍摄效果。
为解决上述技术问题，本申请部分的实施例提供了一种显示面板，包括：第一区域，所述第一区域内设有发光单元，所述发光单元包括第一单元和第二单元，所述第一单元和所述第二单元均包括多种颜色的像素；第二区域，所述第一区域透过率大于所述第二区域透过率，所述第二区域内设有与所述发光单元连接的驱动电路；及透明导线，所述发光单元中至少存在分别位于第一单元和第二单元中的两个颜色相同的像素通过所述透明导线连接。
相应的，本申请的实施例还提供了一种显示装置，包括上述的显示面板。
与现有技术相比，本申请的实施例具有如下优点：
第一区域的透过率大于第二区域，且第一区域内设有发光单元，由于第一区域下方通常对应设置外接的感光元件，因此在感光元件朝向显示面板的一侧不设置驱动电路，能够有效地避免了驱动电路阻挡外界光线射入感光元件，提高光线透过率，从而显示面板在满足全面屏显示的同时，确保了感光元件的光学性能；通过设置透明导线，且发光单元中至少存在分别位于第一单元和第二单元中的两个颜色相同的像素通过透明导线连接，简化第一区域像素与第二区域驱动电路之间导线连接的复杂度，颜色相同的像素之间的透明导线进一步提高了外界光线射入感光元件的透过率，从而使第一区域的透过率不会受到像素之间的导线的影响，进而提高了显示面板的拍摄效果。

本申请的实施例相对于现有技术而言，第一区域1的透过率大于第二区域2，且第一区域1内设有发光单元3，由于第一区域1通常对应外接的感光元件设置，因此在感光元件朝向显示面板100的一侧不设置驱动电路4，能够有效地避免了驱动电路4阻挡外界光线射入感光元件，提高光线透过率，从而确保了感光元件的光学性能；通过设置透明导线5，且发光单元3中至少存在分别位于第一单元301和第二单元302中的两个颜色相同的像素通过透明导线5连接， 简化第一区域像素与第二区域驱动电路之间导线连接的复杂度，颜色相同的像素之间的透明导线不会阻挡外界光线射入感光元件，进一步提高了第一区域1的光线透过率，进而提高了显示面板100的拍摄效果。
本实施例中，第一单元301中像素的颜色种类与第二单元302中像素的颜色种类相同，第一单元301和第二单元302内同一颜色的像素均为一个。
本实施例中，第一单元301与第二单元302相邻设置。
本实施例中，像素为具有第一颜色的第一像素311，或具有第二颜色的第二像素312，或具有第三颜色的第三像素313；发光单元3包括第一单元301和第二单元302，其中，第一单元301和第二单元302单元均包括一个第一像素311、一个第二像素312和一个第三像素313；第一单元301的第一像素311和第二像素312，与相邻的第二单元302的第三像素313沿第二方向Y依次排列，并形成第一结构A；第二单元302的第一像素311和第二像素312，与相邻的第一单元301的第三像素313沿第二方向Y依次排列，并形成第二结构B；第一结构A与第二结构B沿第一方向X依次排列，其中，第一方向X与第二方向Y垂直。
本实施例并不对第一颜色、第二颜色和第三颜色作具体限定，仅需确保第一颜色、第二颜色和第三颜色包括红色、绿色和蓝色即可。
图1所示的显示面板100中，第一方向X为行方向，第二方向Y为列方向，在实际应用中并不对第一方向X和第二方向Y作具体限定，仅需确保第一方向X与第二方向Y垂直即可。此外，图1包括一个第一结构A和一个第二结构B，在实际应用中，并不对第一结构A和第二结构B的数量作具体限定，如第一结构A和第二结构B可以沿第一方向X依次交替设置。
请参见图2，本申请另一实施例提供的显示面板的结构示意图。发光单元3包括多个第一单元301和多个第二单元302；第一单元301沿第一方向X依次排列，第二单元302沿第一方向X依次排列，第一单元301和第二单元302沿第二方向Y依次排列。具体的说，图2所示的发光单元3包括两个第一单元301和两个第二单元302，由于发光单元3包括较多的第一单元301和第二单元302时，会导致单个发光单元3的占用面积过大，而第一区域1的面积固定，使得第一区域1单位面积内的发光单元3数量较少，进而导致第一区域1的显示效 果不佳；发光单元3包括较少的第一单元301和第二单元302时，会导致第一区域1内的发光单元3数量较多，由于发光单元3与驱动电路4一一对应连接，因此会导致第二区域2内的驱动电路4较多，进而导致第二区域2的显示效果不佳，通过设置如图2所示密度的第一单元301和第二单元302，能够同时确保第一区域1和第二区域2的显示效果。值得一提的是，通过设置此种像素排列方式的发光单元3，能够使发光单元3内连接像素的导线数量最少，简化了第一区域走线复杂度，进而简化了显示面板100的制备流程。
进一步的，第一单元301的第一像素311与相邻的第二单元302的第一像素311通过透明导线5C连接。通过此种方式，使得相邻的第一像素311之间的导线不会阻挡外界光线射入感光元件，从而使第一区域1的透过率不会受到相邻的第一像素311之间的导线的影响，从而进一步提高了显示面板的拍摄效果。
优选地，第一单元301的第二像素312与相邻的第二单元302的第二像素312通过透明导线5B连接。通过此种方式，使得相邻的第二像素312之间的导线不会阻挡外界光线射入感光元件，从而使第一区域1的透过率不会受到相邻的第二像素312之间的导线的影响，从而进一步提高了显示面板的拍摄效果。
值得一提的是，本实施例提及的透明导线5为单层结构，实现了像素之间电性连接效果，也可以简化制备流程；显示面板100还包括金属导线7，金属导线7在垂直于显示面板100的厚度方向上的投影，与至少一条透明导线5在垂直于显示面板100的厚度方向上的投影交叠。由于透明导线5与金属导线7的材料不同，因此在显示面板的制备过程中，透明导线5与金属导线7是不同层设置的(也即透明导线5与金属导线7之间设有绝缘层)，通过此种方式，即可避免发光单元3中交叉的导线产生信号串扰。
更优的，显示面板100第二区域2内设有金属层(图未示出)，金属层包括栅极、栅极走线、扫描信号线和EM电路等，金属层材料包括金属Mo，金属导线7与金属层同层设置。通过此种结构的设置，能够使显示面板100在制备金属层时，可以将金属导线7一同制备出来，从而无需额外的工艺流程制备金属导线7，进而简化了显示面板100的制备流程。本实施例中的第一区域1下方通常对应设置外接的感光元件；第二区域2为包围第一区域1的过渡区，显示面板还包括主显示区，主显示区与第二区域2邻接，或者第二区域2为包围第 一区域1的主显示区，第二区域设置有发光单元。
通过将第一区域一部分像素之间的连接线设为单层透明导线，提高光线透过率又简化工艺制备流程；另一部分像素之间的连线设为金属导线，与第二区域的金属层同层，无需额外制备，有利于提高制备效率。
在一个可行的实施例中，第一单元301的第三像素313与相邻的第一单元301的第三像素313通过透明导线5A连接；第二单元302的第三像素313与相邻的第二单元302的第三像素313通过透明导线5A连接；靠近驱动电路4的第一单元301的第三像素313与相邻的第二单元302的第三像素313通过金属导线7连接。不难发现，图2所示的靠近驱动电路4的第一单元301的第三像素313与相邻的第二单元302的第三像素313之间的导线，会与相邻的第一像素311之间的导线和相邻的第二像素312之间的导线交叉，由于透明导线5为单层结构，为了避免交叉的导线产生信号串扰，通过将靠近驱动电路4的第一单元301的第三像素313与相邻的第二单元302的第三像素313通过金属导线7连接，提高了显示面板100的可靠性。
请参见图3，本申请又一实施例提供的显示面板的结构示意图。驱动电路4包括第一像素电路41、第二像素电路42和第三像素电路43；靠近驱动电路4的第一单元301的第一像素311与第一像素电路41连接，靠近驱动电路4的第一单元301的第二像素312与第二像素电路42连接，靠近驱动电路4的第二单元302的第三像素313与第三像素电路43连接。也就是说，一个像素电路对应连接一种颜色的像素，如图3所示的发光单元3中，以第一像素311为例，第一像素311为四个，四个像素311通过三条透明导线5连接，第一像素电路41与最靠近驱动电路4的第一像素311通过走线6连接。也就是说，一个第一像素电路41控制一个发光单元3中的四个第一像素311共同发光或共同不发光，简化第一区域的走线复杂度，确保光线透过率。
具体的说，第一像素311与第一像素电路41、第二像素312与第二像素电路42以及第三像素313与第三像素电路43均通过透明导线6连接，透明导线6为单层结构。通过此种方式，使得导线6不会阻挡外界光线射入感光元件，从而使第一区域1的透过率不会受到导线6的影响，进而提高了显示面板100的拍摄效果。本实施例中的驱动电路4为TFT层，该TFT层包括有源层、栅绝缘层、栅极、层间绝缘层、源极及漏极。其中，有源层设置于柔性基底上，栅 绝缘层设置于有源层上，栅极设置于栅绝缘层上，层间绝缘层设置于栅极上。源极的一端与漏极的一端通过有源层连接，源极的另一端与漏极的另一端分别依次贯穿栅绝缘层、层间绝缘层，延伸至平坦化层中。平坦化层中设有过孔，导线6通过该过孔电连接至源极或漏极(可根据TFT是N型或P型，选择所连接的极)。
在实际应用中，柔性基底可由酰亚胺(PI)、聚碳酸酯(PC)、聚醚砜(PES)、聚对苯二甲酸乙二醇酯(PET)、聚萘二甲酸乙二醇酯(PEN)、多芳基化合物(PAR)或玻璃纤维增强塑料(FRP)等聚合物材料形成。柔性基底可以是透明的、半透明的或不透明的，以对设置在其上的各膜层的形成提供支撑。
有源层可以为铟镓锌氧化物层(indium gallium zincoxide，简称IGZO)。栅绝缘层可以为诸如氧化硅、氮化硅或金属氧化物形成的无机层，并且栅绝缘层可以为单层或多层结构。栅极可以为金(Au)、银(Ag)、铜(Cu)、镍(Ni)、铂(Pt)、钯(Pd)、铝(Al)、钼(Mo)或铬(Cr)形成的单层或多层结构，或者诸如铝(Al)钕(Nd)合金、钼(Mo)钨(W)合金等合金形成的层结构。层间绝缘层可以由氧化硅或氮化硅等绝缘无机材料形成，并且层间绝缘层也可以为单层或多层结构。
在一个实施例中，透明导线5和透明导线6的材料可包括氧化铟锡、氧化铟锌、掺杂银的氧化铟锡、掺杂银的氧化铟锌中的至少一种。如此，可使得透明导电材料的透光率较高。透明导线的材料为掺杂银的氧化铟锡或者掺杂银的氧化铟锌时，可在保证高透光率的基础上，减小电阻。本实施例并不对透明导线的材质作具体限定，透明导线5也可以为其他透过率高的导线。
值得一提的是，由于第二区域2的连接第一区域像素的驱动电路4和主显示区的驱动电路是一同形成的，即第二区域2的驱动电路4和主显示区的驱动电路密度相同，但第二区域2的驱动电路4还要负责第一区域1的发光单元3发光，导致在驱动电压相等的情况下，第二区域2(及第一区域1)的光亮度与主屏的光亮度不同。根据上述分析可知，当需要显示屏的亮度为一目标值时，需要分别对第二区域2(及第一区域1)和主屏的亮度进行补偿。
本实施例中可以通过对显示面板100显示的白画面进行像素亮度采集，得到白画面中所有子像素的实际光学数据，使得采集到子像素的实际光学数据都是白画面(所有子像素均发光)中各种颜色的子像素的亮度数据，从而确保 了数据采集的准确性；再根据实际光学数据得到子像素的补偿光学数据，由于补偿光学数据是白画面中子像素需要补偿的亮度数据，因此通过补偿光学数据对白画面进行亮度调整，补偿的是白画面实际需要补偿的亮度数据，使得亮度调整后的白画面显示亮度均一，不会出现白画面偏色，从而提高了图像画面显示的均匀性。
另一方面，本申请提供一种显示装置，包括上述的显示面板。
其中，显示面板可以为柔性有机发光显示面板或者非柔性有机发光显示面板。该有机发光显示面板的发光模式可以是顶发光、底发光或者双面发光。
显示面板还可以封装在显示装置中，显示装置可以应用在智能穿戴设备(如智能手环、智能手表)中，也可以应用在智能手机、平板电脑、显示器等设备中。
本领域的普通技术人员可以理解，上述各实施例是实现本申请的具体实施例，而在实际应用中，可以在形式上和细节上对其作各种改变，而不偏离本申请的精神和范围。任何本领域技术人员，在不脱离本申请的精神和范围内，均可作各自更动与修改，因此本申请的保护范围应当以权利要求限定的范围为准。
