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。
相关技术中，为了提高显示基板的出光效率，在显示基板的出光侧设置光取出结构。但对于小尺寸高分辨率的显示产品，由于相邻像素之间的间距 很小，光取出结构取出的光线很容易会经相邻像素出射，造成图像模糊的问题。
本公开的实施例提供一种显示基板及其制作方法、显示装置，能够提高显示基板的出光效率，并且避免出现图像模糊。
本公开的实施例提供一种显示基板，包括：
位于衬底基板上阵列排布的多个像素；
位于所述像素远离所述衬底基板一侧的遮光图形，所述遮光图形在所述衬底基板上的正投影与相邻像素之间的间隙在所述衬底基板上的正投影存在重叠；
位于所述像素的出光侧、且位于所述遮光图形靠近所述衬底基板一侧的光取出结构，所述光取出结构的出光方向为所述光取出结构远离所述像素的方向，所述光取出结构在所述衬底基板上的正投影与所述像素在所述衬底基板上的正投影存在重叠。
本实施例中，在像素的出光侧设置有光取出结构，光取出结构可以提高显示基板的出光率；同时在像素远离衬底基板的一侧设置有遮光图形，遮光图形在衬底基板上的正投影与相邻像素之间的间隙在衬底基板上的正投影存在重叠，这样遮光图形可以对经光取出结构取出、射向相邻像素的光线进行遮挡，避免光取出结构取出的光线会经相邻像素出射，进而避免出现图像模糊的问题。
其中光取出结构在衬底基板上的正投影可以位于像素在衬底基板上的正投影内，或者，像素在衬底基板上的正投影位于光取出结构在衬底基板上的正投影内，或者，光取出结构在衬底基板上的正投影与像素在衬底基板上的正投影重合。像素包括阳极、阴极和位于阳极与阴极之间的发光层，像素所在区域即显示基板的像素界定层限定出的区域。
本公开一些实施例中，所述遮光图形在所述衬底基板上的正投影与相邻像素之间的间隙在所述衬底基板上的正投影完全重合，这样遮光图形一方面不会影响显示基板的开口率，另一方面能够最大程度地遮挡经光取出结构取出、射向相邻像素的光线，避免出现图像模糊的问题。
对于集成触控功能的显示基板来说，在显示基板上设置有触控电极。为 了降低触控电极的阻抗同时避让显示基板的发光区，触控电极大多采用金属网格的设计，如图1A和图2所示，触控电极可以采用双层金属的网格状设计，触控电极包括位于同一层的第一触控子电极11和第二触控子电极13，第一触控子电极11沿第二方向排布，第二触控子电极13沿第三方向排布，第三方向和第二方向相互交叉，相邻第二触控子电极13之间直接连接，相邻第一触控子电极11之间通过异层的触控电极架桥12连接。触控电极也可以如图1B和图3所示，采用单层金属的网格状设计，包括位于同一层、多个相互分离的触控子电极14。
如图1C所示，金属网格状的触控电极1限定出的区域为像素2所在区域。
由于触控电极大多采用不透光的金属，具有遮光性能，如图2中箭头所示，经像素2出射、射向相邻像素的光线会被触控电极遮挡；并且网格状的触控电极围绕像素设置，每一金属网格对应所述显示基板的一个像素2，像素2在所述衬底基板上的正投影与对应金属网格限定出的镂空区域在所述衬底基板上的正投影重合，因此可以将触控电极同时作为显示基板的遮光图形。
本公开一些实施例中，显示基板还包括：
覆盖所述多个像素的封装层；
所述遮光图形位于所述封装层远离所述像素的一侧，所述遮光图形采用导电材料，复用为触控电极。
本公开一些实施例中，将遮光图形复用为触控电极，可以简化显示基板的结构，降低显示基板的生产成本。
在显示基板上设置遮光图形后，在像素的出光侧设置光取出结构，可以达到提升光取出效率的效果，由于遮光图形可以对经光取出结构取出、射向相邻像素的光线进行遮挡，避免光取出结构取出的光线会经相邻像素出射，因此，本实施例的技术方案可以应用于小尺寸的显示产品中，达到提高小尺寸的显示产品的光取出效率的目的。
本公开的一些实施例中，所述光取出结构可以包括一个光取出层；或者，从靠近所述衬底基板到远离所述衬底基板的方向上，光取出结构包括依次排布的至少两个光取出层。
如图4所示，本公开的一些实施例中，显示基板包括位于基板3上的像 素界定层7，像素2位于像素界定层7限定出的区域内；覆盖像素2的封装层4；位于封装层4远离像素2的一侧的光取出层9和缓冲层5；位于缓冲层5远离像素2一侧的触控子电极14；覆盖触控子电极14的第二绝缘层6。本实施例中，在像素2的出光侧设置一层光取出层9，光取出层9能够改变像素2出射光线的方向，减小像素2出射光线与第一方向的夹角，增加正向光取出，从而提高显示基板的出光效率，其中，第一方向为垂直于基板3的方向；另外，由于在光取出层9远离像素2的一侧设置有触控子电极14，触控子电极14采用金属制作，具有遮光性能，能够对经光取出层9取出、射向相邻像素的光线进行遮挡，因此，可以避免图像模糊的问题。
如图5所示，本公开的一些实施例中，显示基板包括位于基板3上的像素界定层7，像素2位于像素界定层7限定出的区域内；覆盖像素2的封装层4；位于封装层4远离像素2一侧的光取出层9和缓冲层5；位于缓冲层5远离像素2一侧的触控电极架桥12、第一触控子电极11和第二触控子电极13，第一触控子电极11、第二触控子电极13与触控电极架桥12之间间隔有第一绝缘层8；位于第一绝缘层8远离像素2一侧的第二触控子电极13和第一触控子电极11；覆盖第一触控子电极11和第二触控子电极13的第二绝缘层6。本实施例中，在像素2的出光侧设置一层光取出层9，光取出层9能够改变像素2出射光线的方向，减小像素2出射光线与第一方向的夹角，增加正向光取出，从而提高显示基板的出光效率，其中，第一方向为垂直于基板3的方向；另外，由于在光取出层9远离像素2的一侧设置有第一触控子电极11、第二触控子电极13和触控电极架桥12，第一触控子电极11、第二触控子电极13和触控电极架桥12采用金属制作，具有遮光性能，能够对经光取出层9取出、射向相邻像素的光线进行遮挡，因此，可以避免图像模糊的问题。
如图6所示，本公开的一些实施例中，显示基板包括位于基板3上的像素界定层7，像素2位于像素界定层7限定出的区域内；覆盖像素2的封装层4；位于封装层4远离像素2一侧的光取出层9和缓冲层5；位于缓冲层5远离像素2一侧的触控电极架桥12和光取出层9；位于光取出层9远离像素2一侧的第一绝缘层8；位于第一绝缘层8远离像素2一侧的第二触控子电极 13；覆盖第二触控子电极13的第二绝缘层6。本实施例中，在像素2的出光侧设置两层光取出层9，光取出层9能够改变像素2出射光线的方向，减小像素2出射光线与第一方向的夹角，增加正向光取出，从而提高显示基板的出光效率，其中，第一方向为垂直于基板3的方向；另外，由于在光取出层9远离像素2的一侧设置有第二触控子电极13和触控电极架桥12，第二触控子电极13和触控电极架桥12具有遮光性能，能够对经光取出层9取出、射向相邻像素的光线进行遮挡，因此，可以避免图像模糊的问题。本实施例中，显示基板设置有两层光取出层9，相比设置单层光取出层，能够进一步提高显示基板的光取出效率。
由于光取出层采用透光材料制作，不影响光线的出射，因此光取出层可以设计为一整层，这样可以简化光取出层的制作工艺。在显示基板仅包括单层光取出层时，光取出层可以仅设置在显示基板的部分区域，比如光取出层在衬底基板上的正投影与像素在所述衬底基板上的正投影重合；或者，光取出层为一整层。在显示基板包括至少两层光取出层时，其中至少一层可以仅设置在显示基板的部分区域，其他的光取出层可以为一整层；或者，所有的光取出层均为一整层；或者，所有的光取出层仅设置在显示基板的部分区域。
本公开的一些实施例中，如图7所示，显示基板包括位于基板3上的像素界定层7，像素2位于像素界定层7限定出的区域内；覆盖像素2的封装层4；位于封装层4远离像素2的一侧的光取出层9；位于光取出层9远离基板3一侧的缓冲层5；位于缓冲层5远离像素2一侧的触控电极架桥12和光取出层9；位于光取出层9远离像素2一侧的第一绝缘层8；位于第一绝缘层8远离像素2一侧的第二触控子电极13；覆盖第二触控子电极13的第二绝缘层6。本实施例中，在像素2的出光侧设置两层光取出层9，光取出层9能够改变像素2出射光线的方向，减小像素2出射光线与第一方向的夹角，增加正向光取出，从而提高显示基板的出光效率，其中，第一方向为垂直于基板3的方向；另外，由于在光取出层9远离像素2的一侧设置有第二触控子电极13和触控电极架桥12，第二触控子电极13和触控电极架桥12具有遮光性能，能够对经光取出层9取出、射向相邻像素的光线进行遮挡，因此，可以避免图像模糊的问题。本实施例中，显示基板设置有两层光取出层9，其 中，靠近像素2的光取出层设计为一整层，远离像素2的光取出层仅占据显示基板的部分区域。
本公开的一些实施例中，所述光取出层包括第一光取出层，所述第一光取出层包括层叠设置的至少两层透光材料层，从靠近所述衬底基板到远离所述衬底基板的方向上、透光材料层的折射率呈递增趋势，这样可以使得光取出层9改变像素2出射光线的方向，减小像素2出射光线与第一方向的夹角，增加正向光取出。
或者，从靠近所述衬底基板到远离所述衬底基板的方向上、透光材料层的折射率呈高低交替排布的趋势，比如从靠近所述衬底基板到远离所述衬底基板的方向上、依次排布有第1透光材料层、第2透光材料层、第3透光材料层、第4透光材料层、…、第m透光材料层，其中，第2透光材料层的折射率大于第1透光材料层的折射率，第3透光材料层的折射率小于第2透光材料层的折射率，第4透光材料层的折射率大于第3透光材料层的折射率，以此类推。第一光取出层包括的至少两层透光材料层中，其中至少一层透光材料层可以为一整层，其他层透光材料层仅设置在显示基板的部分区域；或者，所有的透光材料层均为一整层；或者，所有的透光材料层仅设置在显示基板的部分区域。
本公开的一些实施例中，如图8所示，所述第一光取出层包括层叠设置的第一透光材料层91和第二透光材料层92，所述第二透光材料层92位于所述第一透光材料层91远离衬底基板的一侧，所述第一透光材料层91朝向所述第二透光材料层92的一侧表面设置有多个凹槽10。其中，第一透光材料层91的折射率小于第二透光材料层92的折射率，第一透光材料层91表面的凹槽10可以阵列排布，像素2出射的光线照射到第一透光材料层91与第二透光材料层92之间的界面时，会发生偏折，朝向像素2中心的方向出射，从而增加正向光取出，提高显示基板的出光效率。其中，所述凹槽10在平行于衬底基板的方向上的截面可以为圆形或矩形，当然，凹槽10在平行于衬底基板的方向上的截面并不局限为圆形或矩形，还可以为其他形状。
本公开的一些实施例中，如图9所示，所述第一光取出层包括层叠设置的第三透光材料层93、第四透光材料层94和第五透光材料层95，从靠近所 述衬底基板到远离所述衬底基板的方向上、透光材料层的折射率呈递增趋势，这样像素2出射的光线照射到相邻两层透光材料层之间的界面时，会发生偏折，朝向像素2中心的方向出射，从而增加正向光取出，提高显示基板的出光效率。
本公开的一些实施例中，如图10所示，所述光取出层包括第二光取出层，所述第二光取出层包括透光材料层96和位于所述透光材料层96内的多个折射粒子97，所述折射粒子97的折射率大于所述透光材料层96的折射率，这样像素2出射的光线照射到透光材料层96中，经透光材料层96出射时，会发生偏折，朝向像素2中心的方向出射，从而增加正向光取出，提高显示基板的出光效率。
显示基板的绝缘膜层包括封装层中的无机绝缘层，还包括缓冲层、第一绝缘层、第二绝缘层等，这些绝缘膜层都是采用透光绝缘材料制作，为了简化显示基板的结构，组成光取出层的至少一层透光材料层可以复用所述显示基板的以下至少一种绝缘膜层：无机绝缘层、缓冲层、第一绝缘层和第二绝缘层。

本公开实施例还提供了一种显示装置，包括如上所述的显示基板。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：电视、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。
本公开实施例还提供了一种显示基板的制作方法，包括：
在衬底基板上形成阵列排布的多个像素；
在所述像素远离所述衬底基板的一侧形成遮光图形，所述遮光图形在所 述衬底基板上的正投影与相邻像素之间的间隙在所述衬底基板上的正投影存在重叠；
在所述像素的出光侧、所述遮光图形靠近所述衬底基板的一侧形成光取出结构，所述光取出结构的出光方向为所述光取出结构远离所述像素的方向，所述光取出结构在所述衬底基板上的正投影与所述像素在所述衬底基板上的正投影存在重叠。
本实施例中，在像素的出光侧设置有光取出结构，光取出结构可以提高显示基板的出光率；同时在像素远离衬底基板的一侧设置有遮光图形，遮光图形在衬底基板上的正投影与相邻像素之间的间隙在衬底基板上的正投影存在重叠，这样遮光图形可以对经光取出结构取出、射向相邻像素的光线进行遮挡，避免光取出结构取出的光线会经相邻像素出射，进而避免出现图像模糊的问题。
本实施例的显示基板的制作方法用以制作上述实施例所述的显示基板，其中光取出结构在衬底基板上的正投影可以位于像素在衬底基板上的正投影内，或者，像素在衬底基板上的正投影位于光取出结构在衬底基板上的正投影内，或者，光取出结构在衬底基板上的正投影与像素在衬底基板上的正投影重合。像素包括阳极、阴极和位于阳极与阴极之间的发光层，像素所在区域即显示基板的像素界定层限定出的区域。
本公开一些实施例中，所述遮光图形在所述衬底基板上的正投影与相邻像素之间的间隙在所述衬底基板上的正投影完全重合，这样遮光图形一方面不会影响显示基板的开口率，另一方面能够最大程度地遮挡经光取出结构取出、射向相邻像素的光线，避免出现图像模糊的问题。
对于集成触控功能的显示基板来说，在显示基板上设置有触控电极。为了降低触控电极的阻抗同时避让显示基板的发光区，触控电极大多采用金属网格的设计，如图1A和图2所示，触控电极可以采用双层金属的网格状设计，触控电极包括位于同一层的第一触控子电极11和第二触控子电极13，第一触控子电极11沿第二方向排布，第二触控子电极13沿第三方向排布，第三方向和第二方向相互交叉，相邻第二触控子电极13之间直接连接，相邻第一触控子电极11之间通过异层的触控电极架桥12连接。触控电极也可以如图 1B和图3所示，采用单层金属的网格状设计，包括位于同一层、多个相互分离的触控子电极14。
如图1C所示，金属网格状的触控电极1限定出的区域为像素2所在区域。
由于触控电极大多采用不透光的金属，具有遮光性能，如图2中箭头所示，经像素2出射、射向相邻像素的光线会被触控电极遮挡；并且网格状的触控电极围绕像素设置，每一金属网格对应所述显示基板的一个像素2，像素2在所述衬底基板上的正投影与对应金属网格限定出的镂空区域在所述衬底基板上的正投影重合，因此可以将触控电极同时作为显示基板的遮光图形。
本公开一些实施例中，显示基板的制作方法包括：
形成覆盖所述多个像素的封装层；
在所述封装层远离所述像素的一侧形成遮光图形，所述遮光图形采用导电材料，复用为触控电极。
本实施例中，将遮光图形复用为触控电极，可以简化显示基板的结构，降低显示基板的生产成本。
在显示基板上设置遮光图形后，在像素的出光侧设置光取出结构，可以达到提升光取出效率的效果，由于遮光图形可以对经光取出结构取出、射向相邻像素的光线进行遮挡，避免光取出结构取出的光线会经相邻像素出射，因此，本实施例的技术方案可以应用于小尺寸的显示产品中，达到提高小尺寸的显示产品的光取出效率的目的。
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。
