下面结合附图和实施例对本申请作进一步说明。
参见图1至图4，是本发明实施例提供的显示面板的结构示意图。其中，显示面板可以为LCD。
如图1至图4所示，本发明实施例提供的显示面板包括多个子像素开口区P，多个子像素开口区P间隔设置且呈阵列分布，每个子像素开口区P对应设置一个子像素。不同子像素开口区P的大小可以相同或不同。
显示面板包括聚光层1，聚光层1包括多个聚光结构11和多个光隔离结构12。其中，多个聚光结构11间隔设置，且聚光结构11的数量可以与子像素开口区P的数量相同，多个聚光结构11一一对应设置在多个子像素开口区P。聚光结构11的设置，可以将背光源发出的光聚集在子像素开口区P后射出，提高显示面板的光利用率，且减少通向非子像素开口区（即多个子像素开口区P之间的区域）的光量，降低暗态亮度，提高显示对比度。
光隔离结构12设置在非子像素开口区，且任意相邻两个聚光结构11之间具有一个光隔离结构12。聚光结构11与光隔离结构12可以间隔设置，也可以相邻接（即聚光结构11与光隔离结构12之间无间隔）。光隔离结构12的设置，可以进一步减少通向非子像素开口区的光量，进一步降低暗态亮度，提高显示对比度，且可以减少相邻不同颜色光的干涉，提高显示效果。
光隔离结构12的高度不大于聚光结构11的高度，以避免光隔离结构12的设置过高影响聚光结构11的聚光效果。其中，聚光结构11的高度范围为2um至10um。
在一个实施方式中，如图1和图2所示，每个聚光结构11为一个聚光单元。聚光结构11的入光面为凸面，入光面是指聚光结构11朝向背光源一侧的表面，凸面是指聚光结构11的入光面朝向背光源凸起。该凸面可以为圆弧凸面，也可以为其他形状凸面，只要能达到聚光效果即可，此处不作具体限定。不同聚光结构11的入光面的形状（即凸面形状）可以相同或不同。聚光结构11的出光面为平面，出光面是指聚光结构11背离背光源一侧的表面。如图5至图8所示，聚光结构11的出光面可以呈规则形状，如圆形、椭圆形、多边形等，聚光结构11的出光面也可以呈不规则形状，此处不做具体限定。不同聚光结构11的出光面的形状可以相同或不同。例如，每个聚光结构11呈凸球型。
在另一个实施方式中，如图3和图4所示，聚光结构11包括并列设置的多个聚光单元10，不同聚光结构11中的聚光单元10的个数可以相同或不同。每个聚光单元10的入光面为凸面，该凸面可以为圆弧凸面，也可以为其他形状凸面。同一聚光结构11中不同聚光单元10的入光面的形状可以相同或不同，不同聚光结构11中聚光单元10的入光面的形状可以相同或不同。如图9所示，每个聚光单元10的出光面可以呈规则形状，如圆形、椭圆形、多边形等，每个聚光单元10的出光面也可以呈不规则形状。同一聚光结构11中不同聚光单元10的出光面的形状可以相同或不同，不同聚光结构11中聚光单元10的形状可以相同或不同。例如，每个聚光单元10呈凸球型。
由于不同子像素开口区P的大小可以相同或不同，因此可以根据不同子像素开口区P的大小来设置其中的聚光结构11，即可以根据不同子像素开口区P的大小来设置聚光结构11中聚光单元10的数量、形貌和口径大小（即出光面的面积）等，以使显示面板的光利用率达到最佳。例如，在聚光结构11中聚光单元10的数量和形貌固定时，在一定范围内聚光单元10的口径越大，显示面板的光利用率越高。
聚光结构11可以位于对应的子像素开口区P内，也可以完全覆盖对应的子像素开口区P。在一些实施例中，每个聚光结构11均恰好覆盖对应的子像素开口区P，以尽可能将照射至非子像素开口区的光聚拢至子像素开口区P，提高显示面板的光利用率。
聚光结构11的材料为高折射率材料且高穿透率材料，聚光结构11的折射率大于或等于1.6，穿透率大于90%。例如，聚光结构11的材料为丙烯酸类树脂类材料等。
如图2至图4所示，多个光隔离结构12包括反射结构12a和吸光结构12b中的至少一种。也就是说，如图4所示，多个光隔离结构12可以全部为反射结构12a；如图3所示，多个光隔离结构12可以全部为吸光结构12b；如图2所示，多个光隔离结构12可以部分为反射结构12a，部分为吸光结构12b。
反射结构12a用于将照射至非子像素开口区的光反射至子像素开口区P，进一步增加子像素开口区P的光量，提高显示面板的光利用率。吸光结构12b用于吸收照射至非子像素开口区的光，进一步减少非子像素开口区的光量，从而降低暗态亮度，增加显示对比度。另外，吸光结构12b还可以吸收多余的相邻干涉颜色光。
如图2所示，在多个光隔离结构12包括多个反射结构12a和多个吸光结构12b时，多个反射结构12a和多个吸光结构12b可以交替排列，即任意相邻两个反射结构12a之间具有一个吸光结构12b，任意相邻两个吸光结构12b之间具有一个反射结构12a。在多个光隔离结构12全部为反射结构12a时，可能导致反射率过强，影响显示效果。而通过反射结构12a和吸光结构12b交替排列的设置方式，可以在增加光利用率的同时，降低反射率，有效提高显示效果。
反射结构12a可以为掺杂有散射型粒子的白色光阻，散射型粒子可以包括二氧化钛等，反射结构12a也可以为金属膜，如铝膜等。吸光结构12b的材料可以为黑色树脂等。
如图1至图4所示，聚光层1还可以包括平坦层13，平坦层13可以填充在多个聚光结构11和多个光隔离结构12之间，并覆盖多个聚光结构11和多个光隔离结构12，以保证平坦层13的入光面（即平坦层13靠近背光源一侧的表面）为平面。
平坦层13的折射率小于聚光结构11的折射率。背光源发出的光先经过低折射率的平坦层13再经过高折射率的聚光结构11，有效提高折射效果，进而提高光聚拢效果。平坦层13的材料为低折射率材料，例如硅氧烷聚合物等。
如图1至图4所示，显示面板包括彩膜基板8，彩膜基板8包括上述聚光层1。彩膜基板8还可以包括彩膜层2，彩膜层2可以包括多个色阻单元21，多个色阻单元21可以包括多种颜色色阻单元，如红色色阻单元R、蓝色色阻单元B、绿色色阻单元G等。多个色阻单元21间隔设置，且多个色阻单元21的数量与子像素开口区P的数量相同，多个色阻单元21一一对应设置在多个子像素开口区P，使得同一子像素开口区P处的色阻单元21和聚光结构11对应设置，即多个色阻单元21与多个聚光结构11一一对应设置。聚光结构11在彩膜层2上的正投影可以位于对应的色阻单元21内，也可以完全覆盖对应的色阻单元21。
彩膜层2还可以包括多个遮光块22，任意相邻两个色阻单元21之间具有一个遮光块22，且多个遮光块22与多个光隔离结构12一一对应设置。光隔离结构12在彩膜层2上的正投影可以位于对应的遮光块22内，也可以恰好覆盖对应的遮光块22。也就是说，光隔离结构12的宽度不大于对应的遮光块22的宽度，以避免光隔离结构12的设置对显示面板的显示效果产生影响。聚光结构11的侧面可以与遮光块22的内侧平齐，以尽可能将照射至非子像素开口区的光聚拢至子像素开口区P，提高显示面板的光利用率。
彩膜基板8还可以包括彩膜衬底7。聚光层1位于彩膜衬底7与彩膜层2之间，或者彩膜层2位于聚光层1与彩膜衬底7之间。彩膜基板8还可以包括光阻层6，光阻层6位于彩膜层2背离彩膜衬底7的一侧。在彩膜层2位于聚光层1与彩膜衬底7之间时，光阻层6位于彩膜层2与聚光层1之间。
显示面板还可以包括阵列基板4，阵列基板4与彩膜基板8相对设置。阵列基板4可以包括阵列衬底（图中未示出），以及位于阵列衬底上的阵列层（图中未示出）。阵列层可以包括多个薄膜晶体管（图中未示出），与多个子像素开口区P一一对应设置。显示面板还可以包括液晶层5，液晶层5封装在阵列基板4与彩膜基板8之间。
显示面板还可以包括背光模组9，阵列基板4位于背光模组9上。背光模组9可以包括背光源（图中未示出），用于向显示面板提供光源。背光模组9还可以包括依次设置的反射片（图中未示出）、导光板（图中未示出）、扩散片（图中未示出）、下增光片（图中未示出）和上增光片（图中未示出）。反射片可以设于背板（图中未示出）上，导光板设于反射片上，扩散片设于导光板上，下增光片设于扩散片上，上增光片设于下增光片上，背光源设于反射片背离导光板的一侧。其中，扩散片用于对背光源发出的光扩散以提供一个均匀的面光源，下增光片和上增光片用于增强光源的亮度。
在一个实施方式中，如图1和图3所示，聚光层1位于背光模组9与彩膜层2之间。具体地，聚光层1位于液晶层5与光阻层6之间，彩膜层2位于光阻层6与彩膜衬底7之间。背光源发出的光经聚光层1聚拢至子像素开口区P后再经彩膜层2射出，有效提高显示面板的光利用率。
在另一个实施方式中，如图2和图4所示，彩膜层2位于背光模组9与聚光层1之间。具体地，彩膜层2位于光阻层6与彩膜衬底7之间，聚光层1位于彩膜层2与彩膜衬底7之间。背光源发出的光经彩膜层2后再经过聚光层1聚拢至子像素开口区P，有效提高显示面板的光利用率。
本申请实施例通过设置聚光层，使聚光层中的多个聚光结构一一对应设置在多个子像素开口区，以将光聚集在子像素开口区射出，且任意相邻两个聚光结构之间设置一个光隔离结构，减少通向非子像素开口区的光量，从而提高显示装置的光利用率，且降低暗态亮度，提高显示对比度，进而提高显示效果。
相应的，本发明实施例还提供一种显示面板的制作方法，能够制作上述实施例中的显示面板。
如图10所示，本发明实施例提供的显示面板的制作方法，所述显示面板包括多个子像素开口区，所述方法包括步骤101，具体如下：
步骤101、形成聚光层，所述聚光层包括多个聚光结构和多个光隔离结构，所述多个聚光结构一一对应设置在所述多个子像素开口区，任意相邻两个所述聚光结构之间具有一个所述光隔离结构。
其中，光隔离结构采用黄光工艺制作而成，聚光结构采用黄光工艺或纳米压印工艺制作而成。例如，先涂布光隔离材料层，再经过曝光、显影、烘烤等步骤，将光隔离材料层刻蚀为多个光隔离结构。多个光隔离结构间隔出多个开口，在光隔离结构上涂布高折射率材料层，且高折射率材料层填充多个开口。再经过曝光、显影、烘烤等步骤，将高折射率材料层刻蚀为多个聚光结构，且多个聚光结构一一对应位于多个开口中。光隔离结构和聚光结构的制作工艺简单，且当前产线试做设备即可进行制作。
聚光层还包括平坦层，在制作形成多个聚光结构和多个光隔离结构后，在多个聚光结构和多个光隔离结构上覆盖低折射率材料，以形成平坦层。
进一步地，所述方法还包括形成彩膜衬底、彩膜层和光阻层，以使彩膜衬底、彩膜层、光阻层和聚光层构成彩膜基板。

然后，在彩膜层2上形成光阻层6，在光阻层6上形成聚光层1，从而构成彩膜基板8。聚光层1包括形成于光阻层6上的多个聚光结构11和多个光隔离结构12，多个聚光结构11一一对应设置于子像素开口区P，使多个聚光结构11与多个色阻单元21一一对应设置，多个光隔离结构12与多个遮光块22一一对应设置，且任意相邻两个聚光结构11之间具有一个光隔离结构12。聚光层1还包括平坦层13，平坦层13覆盖多个聚光结构11和多个光隔离结构12，且平坦层13背离光阻层6一侧的表面为平面。
然后，将彩膜基板8与阵列基板4对盒设置，使彩膜衬底7背向阵列基板4设置。然后，在彩膜基板8与阵列基板4之间填充液晶层5，从而构成显示面板。
在另一个实施方式中，如图2和图4所示，先提供彩膜衬底7，在彩膜衬底7上形成聚光层1。聚光层1包括形成于彩膜衬底7上的多个聚光结构11和多个光隔离结构12，多个聚光结构11一一对应设置于子像素开口区P，任意相邻两个聚光结构11之间具有一个光隔离结构12，光隔离结构12位于非子像素开口区。聚光层1还包括平坦层13，平坦层13覆盖多个聚光结构11和多个光隔离结构12，且平坦层13背离光阻层6一侧的表面为平面。

综上，本申请实施例通过设置聚光层，使聚光层中的多个聚光结构一一对应设置在多个子像素开口区，以将光聚集在子像素开口区射出，且任意相邻两个聚光结构之间设置一个光隔离结构，减少通向非子像素开口区的光量，从而提高显示装置的光利用率，且降低暗态亮度，提高显示对比度，进而提高显示效果。
综上所述，虽然本申请已以优选实施例揭露如上，但上述优选实施例并非用以限制本申请，本领域的普通技术人员，在不脱离本申请的精神和范围内，均可作各种更动与润饰，因此本申请的保护范围以权利要求界定的范围为准。
