具体实施方式
为使本公开的实施例要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
本公开的实施例提供一种显示面板及显示装置，能够实现中大尺寸显示产品设置屏下摄像头。
本公开的实施例提供一种显示面板，如图1所示，包括显示区域S1和位于所述显示区域S1周边的***区域S3，所述***区域S3包括封装区S2和屏下摄像头区S4，所述屏下摄像头区S4位于所述显示区域S2和所述封装区S2之间，所述显示面板还包括包围所述屏下摄像头区S4的过渡区域，所述显示面板包括相对设置的对置基板和阵列基板，
在所述屏下摄像头区，所述对置基板和所述阵列基板均为透光区域；
在所述过渡区域，所述对置基板上设置有至少一圈包围所述屏下摄像头区的隔垫物，每圈隔垫物包括多个间隔排布的隔垫物。
本实施例中，在屏下摄像头区，所述对置基板和所述阵列基板均为透光区域；能够实现屏下摄像头区的高透过率，保证屏下摄像头能够收集到足够的光线；并且，在过渡区域，对置基板上设置有至少一圈包围屏下摄像头区的隔垫物，每圈隔垫物包括多个间隔排布的隔垫物，过渡区域的隔垫物能够保证屏下摄像头区的盒厚的均一性，避免屏下摄像头区由于盒厚不均导致的发黄现象，实现中大尺寸显示产品设置屏下摄像头。
液晶显示面板包括相对设置的对置基板和阵列基板，如图4所示，对置基板依次包括第一衬底基板25、位于第一衬底基板上的黑矩阵02和彩膜层、位于黑矩阵上的平坦层26、位于平坦层26上的取向层24、隔垫物等；阵列 基板包括第二衬底基板21、位于第二衬底基板21上的栅绝缘层22、栅金属层、层间绝缘层、源漏金属层、钝化层23、取向层24；在两个取向层24之间设置有液晶层27。其中，在屏下摄像头区，对置基板上可以不设置黑矩阵和彩膜层，阵列基板上可以不设置金属膜层，从而实现屏下摄像头区均为透光区域，能够透过白光，保证屏下摄像头能够收集到足够的光线。
对于小尺寸的显示产品，屏下摄像头的尺寸比较小，可以直接在显示区域进行挖孔放置屏下摄像头；对于中大尺寸的显示产品，屏下摄像头的尺寸比较大，在显示区域进行挖孔放置屏下摄像头会对显示造成比较明显的影响，需要将屏下摄像头区放置在***区域，在屏下摄像头区去除阵列基板和对置基板上不透光的膜层(包括栅金属层和源漏金属层)，实现屏下摄像头区的高透过率，保证屏下摄像头能够收集到足够的光线；另外，为了保证高透过率，在屏下摄像头区未设置隔垫物，这会影响屏下摄像头区的盒厚的均一性，屏下摄像头区会出现发黄现象，影响成像效果，本实施例中，在包围屏下摄像头区S4的过渡区域设置至少一圈隔垫物，能够对盒厚进行支撑，保证屏下摄像头区的盒厚的均一性，避免屏下摄像头区由于盒厚不均导致的发黄现象，实现中大尺寸显示产品设置屏下摄像头。
本实施例中，屏下摄像头区的形状与屏下摄像头的形状相匹配，可以是圆形或者方形，屏下摄像头区的尺寸与屏下摄像头的尺寸相匹配，屏下摄像头区的尺寸可以稍大于屏下摄像头的尺寸。在屏下摄像头区为圆形时，为了避免对显示面板外观的影响，屏下摄像头区的直径可以小于等于4mm。
图2和图3为本公开实施例屏下摄像头区的平面示意图，图4为图3在AA方向上的截面示意图，如图2-图4所示，在屏下摄像头区周边的过渡区域，设置有多圈隔垫物(包括第一隔垫物031和第二隔垫物032)，为了在屏下摄像头区周边形成平缓的过渡，过渡区域分为第一过渡区和第二过渡区，其中，第一过渡区紧邻所述屏下摄像头区且包围所述屏下摄像头区，第二过渡区位于所述第一过渡区远离所述屏下摄像头区一侧且包围所述屏下摄像头区。
如图2-图4所示，在所述第一过渡区S6，所述对置基板包括第一衬底基 板25，位于所述第一衬底基板25上的黑矩阵02、平坦层26、取向层24和位于所述黑矩阵02远离所述第一衬底基板25一侧的至少一圈第一隔垫物031；在第一过渡区S6，每圈所述第一隔垫物031包括多个间隔排布的所述第一隔垫物031，所述第一隔垫物031围绕所述屏下摄像头区S4排布。其中，如图2所示，可以设置两圈第一隔垫物031，也可以如图3所示，设置一圈第一隔垫物031。在第一过渡区S6，第一隔垫物031能够对屏下摄像头区S4的盒厚进行支撑，保证屏下摄像头区的盒厚的均一性，避免屏下摄像头区由于盒厚不均导致的发黄现象。
为了实现第一过渡区S6到***区域的过渡，过渡区域还包括第二过渡区S7，如图2-图4所示，在第二过渡区S7，所述对置基板包括第一衬底基板25，位于所述第一衬底基板25上的黑矩阵02、位于黑矩阵02上的彩膜图形01、平坦层26、取向层24和位于彩膜图形01远离所述第一衬底基板25一侧的至少一圈第二隔垫物032；在第二过渡区S7，每圈所述第二隔垫物032包括多个间隔排布的所述第二隔垫物032，所述第二隔垫物032围绕所述屏下摄像头区S4排布。其中，如图2和图3所示，可以设置两圈第二隔垫物032，也可以设置多圈第二隔垫物032。在第二过渡区S7，第二隔垫物032能够进一步对屏下摄像头区S4的盒厚进行支撑，保证屏下摄像头区的盒厚的均一性，避免屏下摄像头区由于盒厚不均导致的发黄现象。
由于在第一过渡区S6未设置彩膜图形01，在第二过渡区S7设置了彩膜图形01，因此，可以设计第一隔垫物031的高度大于所述第二隔垫物032的高度，这样可以保证第一过渡区S6的盒厚与第二过渡区S7的盒厚保持一致，所述第一隔垫物031与所述第二隔垫物032的高度差可以为0.4-0.5微米。本实施例中，过渡区域的形状与屏下摄像头区的形状相匹配，可以是圆环形或者方环形，在屏下摄像头区为圆形时，过渡区域为圆环形，内径可以等于或略大于屏下摄像头区的半径，外径与内径之差可以为0.6-0.8mm。第一过渡区的外径与内径之差可以为0.2mm-0.4mm，第一隔垫物的密度可以为每一像素区域大小的范围设置一第一隔垫物031，每圈第一隔垫物中，相邻两个第一隔垫物之间的间距可以为6-7微米。第二过渡区的外径与内径之差可以为 0.4mm-0.6mm，第二隔垫物的密度可以为每一像素区域大小的范围设置一第二隔垫物032，每圈第二隔垫物中，相邻两个第二隔垫物之间的间距可以为6-7微米。彩膜图形01可以为圆形，直径在40-100微米，其中，第二隔垫物032在第一衬底基板25上的正投影可以位于彩膜图形01在第一衬底基板25上的正投影内。
一些实施例中，所述第二隔垫物032远离所述第一衬底基板的端部与所述阵列基板之间的最小距离小于所述第一隔垫物031远离所述第一衬底基板的端部与所述阵列基板之间的最小距离，这样从屏下摄像头区中心往外，隔垫物的支撑高度依次递增，能够形成过渡，避免出现“跷跷板”风险。
在显示面板的显示区域设置有主隔垫物和辅隔垫物，主隔垫物的高度大于辅隔垫物的高度，第一隔垫物的高度可以与显示区域的主隔垫物的高度保持一致；第二隔垫物的高度可以与显示区域的辅隔垫物的高度保持一致；在显示区域，由于蓝色滤光单元的厚度比较均一，因此，隔垫物都设置在蓝色滤光单元远离第一衬底基板的一侧，在过渡区域，第一隔垫物和第二隔垫物也可以都设置在蓝色滤光单元远离第一衬底基板的一侧。
为了实现摄像功能，需要保证屏下摄像头区S4的光线不能被金属阻隔，因此阵列基板上的金属层需要特殊设计，在所述***区域，所述阵列基板包括第二衬底基板和位于所述第二衬底基板上的驱动电路，如图5所示，所述驱动电路避让所述屏下摄像头区S4，所述驱动电路包括以下至少一项：电源电压信号线06、第一公共电压信号线05、接地信号线04、静电释放电路阵列08。其中，驱动电路避让述屏下摄像头区S4，即驱动电路在第二衬底基板21上的正投影与屏下摄像头区S4不重叠。
在***区域，靠近屏下摄像头区S4的接地信号线04的线宽应相应地减少，以实现屏下摄像头区S4的透过率大于或等于90％。在***区域，靠近屏下摄像头区S4的第一公共电压信号线05的线宽应相应地减少，以实现屏下摄像头区S4的透过率大于或等于90％。在***区域，靠近屏下摄像头区S4的电源电压信号线06的线宽应相应地减少，以实现屏下摄像头区S4的透过率大于或等于90％。
在***区域，静电释放电路阵列08的尺寸应当减小，以实现屏下摄像头区S4的透过率大于或等于90％。在行方向上，静电释放电路阵列08的长度应在1mm-4mm内。如图5所示，静电释放电路阵列08靠近所述屏下摄像头区的边界的延伸方向与所述屏下摄像头区靠近所述静电释放电路阵列08的边界的延伸方向相同或大致相同，这样可以有效利用摄像头模组周边空白区域，缓解此区域与显示面板其他区域的差异。
另外，在***区域，虚拟像素09的个数需要减少，以实现屏下摄像头区S4的透过率大于或等于90％。虚拟像素09减小的数量可以根据屏下摄像头区S4的尺寸决定，最少虚拟像素09可以减少至0个。
如图4所示，在屏下摄像头区S4，阵列基板仅包括第二衬底基板21、栅绝缘层22、钝化层23和取向层24，在第一过渡区S6和第二过渡区S7，阵列基板包括第二衬底基板21、第一公共电压信号线05、栅绝缘层22、钝化层23和取向层24，第一公共电压信号线05与隔垫物一起配合支撑屏下摄像头区S4的盒厚。本实施例中，可以是接地信号线04和第一公共电压信号线05与隔垫物一起配合支撑屏下摄像头区S4的盒厚，也可以如图4所示，仅第一公共电压信号线05与隔垫物一起配合支撑屏下摄像头区S4的盒厚，接地信号线04可以完全被覆盖到封装胶内部。
如图6所示，所述显示面板还包括位于所述显示区域的第二公共电压信号线13，显示区域设置有栅线16、数据线11和公共电极14，公共电压信号经由第一公共电压信号线05传递至第二公共电压信号线13，进而传递至公共电极14，为了提高公共电压均一性，可以将公共电压信号通过多点连入显示区域，如图6所示，所述显示面板还包括：连接图形12，通过多个连接点与所述第一公共电压信号线05连接，且通过多个连接点与所述第二公共电压信号线13连接，这样利用连接图形12可以实现将公共电压信号通过多点连入显示区域。其中，连接图形12可以与第一公共电压信号线05、第二公共电压信号线13异层设置，在***区域，连接图形12通过多个过孔15与第一公共电压信号线05连接，在显示区域，连接图形12通过多个过孔15与第二公共电压信号线13连接。
连接图形12上传递公共电压信号时，为了减少公共电压信号对数据线11上数据信号的耦合，如图6所示，所述连接图形12在所述第二衬底基板上的正投影与所述数据线11在所述第二衬底基板上的正投影不重叠。连接图形12可以为梳状，连接图形12的梳柄位于***区域，连接图形12的梳齿位于显示区域。当然，连接图形还可以为其他形状，比如连接图形12为长条形，连接图形12在***区域和显示区域的线宽基本相同。
通过以上实施例，在不改变显示面板边框以及尺寸的前提下，可实现嵌入式屏下摄像头。通过本实施例，能够实现高透过率的屏下摄像头区S4，保证屏下摄像头能够收集到足够的光线。另外，由于中大尺寸显示产品中，屏下摄像头区S4的面积较大，为了保证高透过率，在屏下摄像头区未设置隔垫物，这会影响屏下摄像头区的盒厚的均一性，屏下摄像头区会出现发黄现象，本实施例中，在包围屏下摄像头区S4的过渡区域设置至少一圈隔垫物，能够保证屏下摄像头区的盒厚的均一性，避免屏下摄像头区由于盒厚不均导致的发黄现象，实现中大尺寸显示产品设置屏下摄像头。
本公开的实施例提供了一种显示装置，包括如上所述的显示面板。
该显示装置包括但不限于：射频单元、网络模块、音频输出单元、输入单元、传感器、显示单元、用户输入单元、接口单元、存储器、处理器、以及电源等部件。本领域技术人员可以理解，上述显示装置的结构并不构成对显示装置的限定，显示装置可以包括上述更多或更少的部件，或者组合某些部件，或者不同的部件布置。在本公开实施例中，显示装置包括但不限于显示器、手机、平板电脑、电视机、可穿戴电子设备、导航显示设备等。
所述显示装置可以为：液晶电视、液晶显示器、数码相框、手机、平板电脑等任何具有显示功能的产品或部件，其中，所述显示装置还包括柔性电路板、印刷电路板和背板。
如图7-图10所示，显示装置还包括贴附在所述显示面板1表面的偏光片10，为了保证屏下摄像头区S4的高透过率，所述偏光片10在所述显示面板1上的正投影与所述屏下摄像头区S4不重叠。
一具体实施例中，如图7所示，所述偏光片10包括有开孔101，所述开 孔101在所述显示面板1上的正投影的第一边界包围所述屏下摄像头区S4。开孔101的形状与屏下摄像头区S4的形状相适配，比如，屏下摄像头区S4为圆形，则开孔101为圆形；屏下摄像头区S4为矩形，则开孔101为矩形。开孔101的尺寸应大于屏下摄像头区S4的尺寸，屏下摄像头区S4和开孔101为圆形时，开孔101的半径应大于屏下摄像头区S4的半径+偏光片尺寸精度+设备贴合精度；一些实施例中，所述第一边界与所述屏下摄像头区的第二边界之间的最小距离可以大于2微米。
在擦拭采用图7所示的偏光片的显示面板时，如图8所示，在位置d容易积累灰尘，很难清除位置d的灰尘，为了解决这一问题，如图9所示，一些实施例中，所述偏光片10的边缘包括有凹口102，所述凹口102在所述显示面板上的正投影的边界包围所述屏下摄像头区S4，在擦拭采用图9所示的偏光片的显示面板时，如图10所示，能够很容易将灰尘从屏下摄像头区S4去除。凹口102的形状不做限制；一些实施例中，所述凹口102可以为梯形，偏光片10采用倒梯形留海上开口方式形成凹口102，凹口102的尺寸应大于屏下摄像头区S4的尺寸+偏光片尺寸精度+设备贴合精度，凹口102的两个角α1和α2可以为圆角，角度为90-150°之间，圆角的半径可以为0.5-2.5微米。
通过本实施例，能够实现高透过率的屏下摄像头区S4，保证屏下摄像头能够收集到足够的光线。
需要说明，本说明书中的各个实施例均采用递进的方式描述，各个实施例之间相同相似的部分互相参见即可，每个实施例重点说明的都是与其他实施例的不同之处。尤其，对于实施例而言，由于其基本相似于产品实施例，所以描述得比较简单，相关之处参见产品实施例的部分说明即可。
