透光层13，透光层13形成于彩色色块层12的朝向发光层11的一侧，透光层13的与彩色色块层12连接的一面形成为半透半反面130，半透半反面130被配置为接收自子像素单元110发出的光线，并透过自子像素单元110射向对应的子色块1201的光线，反射自子像素单元110射向对应的子色块1201之外的子色块1201的光线。
作为本公开实施例一种可选的实施方式，半透半反面130被配置为接收自子像素单元110发出的光线，并透过入射角度小于夹角θ的光线，反射入射角度大于或等于夹角θ的光线。其中，夹角θ被配置为：自子像素单元110指向与对应的子色块1201相邻的另一子色块1201的方向与半透半反面130的法向之间形成的夹角。可以理解的是，由于夹角θ可为自子像素单元110的任一位置指向与对应的子色块1201相邻的另一子色块1201的任一位置的方向，与半透半反面130的法向之间形成的夹角，因此，夹角θ的取值不唯一，如图2所示，图2中示例性地示出了两种不同角度的夹角θ的取值情况。
以夹角θ的角度取值为图2中所示的角度较小的夹角θ为例，如图2所示，图2中的粗虚线与箭头示例性地示出了两种不同的光路，其中，一种光路为自子像素单元110射向半透半反面130的入射角度为φ1的光线，该入射角度φ1小于夹角θ，且该光线透过半透半反面130，并射向对应的子色块1201，另一种光路为自子像素单元110射向半透半反面130的入射角度为φ2的光线，该入射角度φ2大于夹角θ，且该光线被半透半反面130反射，无法射向非对应的子色块1201。
作为本公开实施例一种可选的实施方式，透光层13具有折射率n1，彩色色块层12的连接于透光层13的一侧具有折射率n2，该折射率n1与n2可满足：n1＞n2，从而利用光线自高折射率的传播介质射向低折射率的传播介质时，当光线的入射角较大，会发生全反射的性质，使透光层13与彩色色块层12的连接面形成为半透半反面130，换言之，无需额外设置其他的光学结构，即能够使透光层13与彩色色块层12的相连接处形成为，能够透过第一预设角度φ1的光线并反射第二预设角度φ2的光线的半透半反面130。
在其他实施方式中，半透半反面130还可通过在透光层13的朝向发光层11的一侧覆设半透半反膜，或者设置能够实现半透半反功能的光学微结构来形成。
作为本公开实施例一种可选的实施方式，为了使半透半反面130能够将入射角度为第二预设角度φ2的光线尽可能多地甚至全部反射，并透过入射角度为第一预设角度φ1的光线，以实现更好的防串光的效果，可使夹角θ为半透半反面130 的全反射临界角，而全反射临界角可以理解为折射角等于90°时的入射角角度，从而，根据折射率的计算公式，该折射率n1与n2可满足：n2除以sinθ的值小于n1，即，该折射率n1与n2可满足：
作为本公开实施例一种可选的实施方式，考虑到实际情况中，sinθ可大致为0.4≤sinθ≤1，换言之，θ可大致为：23°≤θ≤90°，以折射率n1满足：1≤n1≤1.5为例，此时，折射率n2可大致满足：1.5≤n2≤2.5，例如，折射率n1可为：1、1.1、1.2、1.3、1.4或1.5等，折射率n2可为：、1.5、1.6、1.7、1.8、1.9、2、2.1、2.2、2.3、2.4或2.5等。
作为本公开实施例一种可选的实施方式，沿发光层11指向彩色色块层12的方向上，各子像素单元110的背离彩色色块层12的一侧表面至各子像素单元110之间的距离为h，沿平行于半透半反面130的方向上，对于任意一个子色块1201，对应于子色块1201的子像素单元110与和子色块1201相邻的其他子色块1201之间具有距离a，考虑到各子像素单元110形成为立体的结构，且各子像素单元110的各外表面均可发光，因此，为了更进一步地提升防止串光的效果，可使子像素单元110发出的光线中，射向与对应的子色块1201相邻的子色块1201的光束的最小入射角为夹角θ，即，夹角θ可满足：
可见，射率n1与n2可满足：
从而能够提升防止串光的效果，显示屏1的显示效果更好。
作为本公开实施例一种可选的实施方式，透光层13的材料可包括Al

2中的至少一种材料，以使透光层13具有较高的折射率。
如图3所示，作为本公开实施例一种可选的实施方式，透光层13的背离彩色色块层12的一侧还可覆设有封装层131，从而通过封装层131保护透光层13以及彩色色块层12，以阻隔水氧，并避免透光层13、彩色色块层12在转运的过程中受到破坏。
作为本公开实施例一种可选的实施方式，彩色色块层12还可包括平坦层122，该平坦层122可包括透明有机材料，平坦层122设于多个阵列排布的色块单元120的朝向透光层13的一侧，平坦层122的背离色块单元120的一侧连接于透光层13，平坦层122与透光层13的连接面形成为半透半反面130，换言之，该平坦层122形成为彩色色块层12的连接于透光层13的一侧，因此，该平坦层122具有前文中所述的折射率n2，该平坦层122一方面，用于使彩色色块层12的表面平整，以使半透半反面130形成为形状平整的面，从而半透半反面130在各个不同位置处对相同角度的光线的透过或全反射方向更加统一，以提升半透半反面130整体的防串光功能的有效性及可控性，另一方面，用于使彩色色块层12的连接于透光层13的一侧的折射率更加统一，能够避免由于各子色块1201的折射率不完全相同，而导致半透半反面130各处对光线的全反射临界角存在差异的问题，从而进一步提升半透半反面130整体的防串光功能的有效性及可控性。
作为本公开实施例一种可选的实施方式，彩色色块层12可包括第二遮光结构121以及阵列设于第二遮光结构121的色块单元120，该第二遮光结构121可包括深色，例如黑色或深灰色等颜色的遮光材料，各子色块1201的外周均设置有第二遮光结构121，且相邻的两个子色块1201的外周的第二遮光结构121相连接，从而能够通过第二遮光结构121来遮挡、吸收相邻的两个子色块1201之间的光线， 以减少光线在相邻的两个子色块1201之间发生串光干扰的现象，从而进一步地提升显示屏1的显示效果。
作为本公开实施例一种可选的实施方式，任意相邻的两个子像素单元110之间、以及各子像素单元110与驱动背板10之间可通过填充胶111相固定连接，从而能够通过该填充胶111将各子像素单元110固定于驱动背板10的同时，使任意相邻的两个子像素单元110之间的相对位置稳定，从而使发光层11与驱动背板10之间的连接稳固，并使发光层11整体的结构稳定。
可以理解的是，本公开实施例的显示屏1，可包括但不限于量子点显示屏以及有机发光显示屏等。
以显示屏1为量子点显示屏为例，作为本公开实施例一种可选的实施方式，子像素单元110可被配置为在电流的作用下发出蓝光的结构，例如蓝光发光二极管，各色块单元120可至少包括第一子色块120a、第二子色块120b以及第三子色块120c，第一子色块120a、第二子色块120b包括光致发光材料，第三子色块120c为透光色块，第一子色块120a被配置为接收自对应的子像素单元110发出的蓝光，并在子像素单元110发出的蓝光的激发下发出绿光，第二子色块120b被配置为接收自对应的子像素单元110发出的蓝光，并在子像素单元110发出的蓝光的激发下发出红光，第三子色块120c被配置为接收自对应的子像素单元110发出的蓝光并透出，从而通过各子像素单元110来调整发光亮度，通过各子色块120来调整显示光线的颜色，以实现使显示屏1显示彩色画面的功能。
可以理解的是，此时，第一子色块120a对应的预定波段为在色度学中大致成绿色的光线的波段，第二子色块120b对应的预定波段的光线为在色度学中大致成红色的光线的波段，第三子色块120c对应的预定波段的光线为在色度学中大致成蓝色的光线的波段。在其他实施方式中，子色块1201对应的预定波段还可为其他的任意波段，本实施例不作具体限定。

作为本公开实施例一种可选的实施方式，显示屏1还可包括杂光过滤层14，杂光过滤层14设于彩色色块层12的背离发光层11的一侧，杂光过滤层14可包括第一遮光结构141以及阵列设置于第一遮光结构141的多个过滤单元140，各过滤单元140包括多个子过滤块140a，各子过滤块140a的外周均连接于第一遮光结构141，各子过滤块140a对应于各子色块1201设置，子过滤块140a被配置为供对应的子色块1201所对应的预定波段的光线透过，并阻挡预定波段之外的光线，例如，对应于第一子色块120a的子过滤块140a用于透过绿光，并阻挡除绿光波段之外的波段的光线，对应于第二子色块120b的子过滤块140a用于透过红光，并阻挡除红光波段之外的波段的光线，对应于第三子色块120c的子过滤块140a用于透过蓝光，并阻挡除蓝光波段之外的波段的光线，从而，通过杂光过滤层14来滤除自第一子色块120a、第二子色块120b射出的光线中，未激发量子点材料发光的蓝光，以防止出现显示屏1的显示画面整体偏蓝的情况。该第一遮光结构141可包括深色，例如黑色或深灰色等颜色的遮光材料，从而能够通过第一遮光结构141来遮挡、吸收相邻的两个子过滤块140a之间的光线，以减少光线在相邻的两个子过滤块140a之间发生串光干扰的现象，从而进一步地提升显示屏1的显示效果。
作为本公开实施例一种可选的实施方式，发光层11与透光层13可间隔设置，以避免发光层11与透光层13相碰撞而导致损坏。
如图1所示，作为本公开实施例一种可选的实施方式，显示屏1还可包括框 胶16，框胶16沿发光层11的边缘设置，并连接于发光层11的边缘与彩色色块层12之间，以一方面通过框胶16来使发光层11与彩色色块层12之间形成稳定的间距，另一方面，通过框胶16封闭显示屏1的边缘处，从而包括彩色色块层12以及发光层11，避免水和氧气进入显示屏1的内部，导致光致发光材料、子像素单元110发生发光猝灭。
作为本公开实施例一种可选的实施方式，框胶16可由填充有弹性支撑颗粒的无影胶固化形成，从而框胶16能够支撑、保护发光层11、透光层13以及彩色色块层12的同时，还能够将发光层11与透光层13相胶接，以使显示屏1整体的结构稳定。
作为本公开实施例一种可选的实施方式，显示屏1还可包括封装基板15，封装基板15设于彩色色块层12的背离发光层11的一侧，且封装基板15的边缘位于彩色色块层12的外周，框胶16连接于封装基板15的边缘与发光层11的边缘之间，从而一方面能够通过封装基板15保护彩色色块层12，以使彩色色块层12的形状、结构保持稳定，另一方面，能够通过封装基板15的边缘连接于框胶16，从而能够使彩色色块层12的外周被框胶16包围，以将彩色色块层12整体封装于显示屏1的内部，从而对彩色色块层12的保护效果更好。可以理解的是，当彩色色块层12的背离发光层11的一侧设有杂光过滤层14时，封装基板15可设于杂光过滤层14的背离发光层11的一侧，以通过封装基板15支撑、保护杂光过滤层14以及彩色色块层12。
作为本公开实施例一种可选的实施方式，发光层11与彩色色块层12之间可填充有透明填充胶17，以进一步地避免水和氧气接触彩色色块层12以及发光层11，从而进一步地封装、保护彩色色块层12以及发光层11，其中，为了便于看，图2中省略了透明填充胶17。
本实施例提供的显示屏1，通过设置透光层13以形成半透半反面130，来阻止各子色块1201之间的串光现象，从而缓解了显示屏1的色偏问题，以提升显示屏1的显示效果。
此外，通过在多个阵列排布的色块单元120的朝向透光层13的一侧设置平坦层122，以使得彩色色块层12的连接于透光层13的一侧的折射率一致性高，且该一侧的表面平整度高，从而使半透半反面130的形状、性能在不同的位置的差异均较小，使得半透半反面130在各个不同位置处对相同角度的光线的透过或全反射方向更加统一，半透半反面130整体的防串光功能的有效性及可控性更好。

其中，可通过旋涂工艺、蒸镀工艺或其他膜层成型工艺将高折射率的透光材料覆设于彩色色块层12的一侧，以形成透光层13。从而，无需在透光层13与彩色色块层12之间额外设置连接结构，避免该连接结构影响透光层13与彩色色块层12之间的半透半反面130的半透半反性能。
由前文所述，显示屏1还可包括封装层131，在此一个或多个实施例中，该方法还可包括：
