 本发明的实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。此外，应当理解的是，此处所描述的具体实施方式仅用于说明和解释本申请，并不用于限制本申请。在本申请中，在未作相反说明的情况下，使用的方位词如“上”和“下”通常是指装置实际使用或工作状态下的上和下，具体为附图中的图面方向；而“内”和“外”则是针对装置的轮廓而言的。
本申请实施例提供一种显示面板和拼接面板，下文进行详细说明。需说明的是，以下实施例的描述顺序不作为对实施例优选顺序的限定。
需要说明的是，可选的，拼接面板包括至少两个第一面板和至少一第二面板。至少两个第一面板拼接设置，相邻两个第一面板之间存有缝隙。第二面板设置在相邻的两个第一面板上，并遮挡缝隙。第二面板包括面板主体和光栅层。光栅层设置在面板主体上。面板主体的正视亮度大于第一面板的正视亮度。
请参照图1至图3，本申请第一实施例提供一种显示面板100包括面板主体10和光栅层20。光栅层20形成在面板主体10上。光栅层20包括多个光栅21。多个光栅21沿着第一方向m间隔排列。多个光栅21也沿着第二方向n间隔排列。第一方向m与所述第二方向n交叉设置。
本申请实施例采用光栅层20形成在面板主体10上，也即是将光栅层20集成在面板主体10上，达到了薄化显示面板100的效果；另外采用多个光栅21分别沿着第一方向m和第二方向n间隔排列设置，可以降低侧视亮度。
可选的，光栅层20可以采用转印工艺或冲切工艺直接形成在面板主体10上。
其中，由于在第一方向m和第二方向n上，光栅21均是间隔设置，也即相邻光栅21之间设置有开口k，部分侧向光线可穿过开口k，部分侧向光线被光栅21所遮挡，达到降低侧视亮度，但侧视亮度不为零。也即，在大视角的情况下依然还有侧视的可视性。
另外，需要说明的是，某一视角的侧视亮度低于阈值时，则该视角对于用户而言为不可见视角，也即在该视角下，用户不能看到面板的显示内容。因此通过减低显示面板100的侧视亮度，在一定程度上可以达到缩小视角的效果。
可选的，第一方向m垂直于第二方向n。在一些实施例中，第一方向m非垂直于第二方向n，比如第一方向m与第二方向n的夹角可以为45度、60度或120度等。
可选的，面板主体10可以是LED面板，比如可以是微型LED面板（Micro-LED面板）、次毫米级LED面板（Mini-LED面板）、量子点LED面板（Q-LED面板）或有机发光二极管面板（OLED面板）；或者也可以是液晶显示面板。
可选的，面板主体10包括驱动基板11、发光器件12、封装层13、彩膜层14和平坦层15。
发光器件12设置在驱动基板11上。封装层13覆盖发光器件12。彩膜层14形成在封装层13上。平坦层15形成在彩膜层14上。光栅层20形成在平坦层15上。
可选的，发光器件12发白光，比如发光器件12可以是白光LED发光器件或蓝光LED发光器件搭配光转换膜。彩膜层14用于过滤发光器件12发出的光线形成红绿蓝光。可选的，彩膜层14包括红色色阻、绿色色阻和蓝色色阻。
可选的，驱动基板11包括基底和设置在基底上的薄膜晶体管，薄膜晶体管可以是顶栅型、底栅型或双栅型。
在一些实施例中，面板主体10也可以省略彩膜层14。也即，发光器件12包括发红光的发光器件、发绿光的发光器件和发蓝光的发光器件。亦或者，发光器件12为发单色光的发光器件，可在该发光器件上形成光转换层，以发出红、绿或蓝光。
可选的，显示面板100还可以包括保护层30，保护层30覆盖光栅层20。
可选的，请参照图3，多个光栅21沿着第一方向m延伸。光栅21在第一方向m的长度大于在第二方向n的宽度，当应用于面板时使得在第一方向m可遮挡更多的侧向光线，进而第一方向m的侧视亮度小于第二方向n的侧视亮度。由于第一方向m和第二方向n的侧视亮度不同，便于根据不同的需求进行不同方向的贴附设置，提高光栅层的适用性。
可选的，在第一方向m上，相邻两个光栅21之间的开口宽度为第一宽度。在第二方向n上，相邻两个光栅21之间的开口宽度为第二宽度。第一宽度小于第二宽度，当应用于面板时使得第二方向n更少的侧向光线通过，进而第一方向m的侧视亮度大于第二方向n的侧视亮度。
可选的，光栅21的材料可以是黑色不透光的材料，比如可以是无机的金属材料，如Cr（铬）、Mo（钼）、Mn（锰）等，也可以是金属氧化物材料，如CrO x、MoO x、MnO 2等，或者由金属和金属氧化物形成的混合材料；亦可以是有机黑色树脂材料，如黑色聚苯乙烯、黑色光刻胶等。
可选的，光栅21的形状可以是矩形、梯形或其他形状。
可选的，光栅21的宽度大于或等于8微米，比如8微米、9微米或10微米。光栅21的长度介于35微米至75微米之间，比如35微米、45微米、55微米、65微米或75微米。光栅21的厚度介于50微米至130微米之间，比如50微米、70微米、90微米、110微米或130微米。
可选的，在光栅层20中，多个光栅21均匀排布。
可选的，请参照图4，在本第一实施例的另一俯视结构中，光栅层20包括位于中间区域的第一区q1和设置在第一区q1两侧的第二区q2。位于第一区q1的光栅21的排列密度小于位于第二区q2的光栅21的排列密度。
当本实施的光栅层20应用于拼接面板时，不同排列密度的光栅21进行分区设置，使得第一区q1的正视亮度大于第二区q2的正视亮度，进而使得拼接面板的整体亮度平缓过渡。
可选的，在第二方向n上，位于第一区q1的光栅21之间间距大于位于第二区q2的光栅21之间的间距。
可选的，位于第一区q1的光栅21高度小于位于第二区q2的光栅21高度。这样的设置，位于第一区q1的侧视亮度大于位于第二区q2的侧视亮度。
其中高度方向为垂直于平面mn的方向。
可选的，本申请实施例的显示面板100的制备方法如下：
步骤B1，提供一面板主体10；
步骤B2，在面板主体10上形成光栅层20。
其中步骤B2包括：
步骤B21，在面板主体10上形成光栅材料层。
可选的，光栅材料层的材料可以是黑色不透光的材料，比如可以是无机的金属材料，如Cr（铬）、Mo（钼）、Mn（锰）等，也可以是金属氧化物材料，如CrO x、MoO x、MnO 2等，或者由金属和金属氧化物形成的混合材料；亦可以是有机黑色树脂材料，如黑色聚苯乙烯、黑色光刻胶等。
步骤B22，冲切光栅材料层，形成多个光栅21。
可选的，步骤B22包括以下步骤：
步骤B221，采用第一冲切模具冲切光栅材料层，形成多个第一光栅211；
步骤B222，采用第二冲切模具冲切光栅材料层，形成多个第二光栅212；
步骤B223，去除光栅材料层中第一光栅211和第二光栅212之外的部分。
其中，第一冲切模具开设有与多个第一光栅211相同图案化的第一冲切孔。第二冲切模具开设有与多个第二光栅212相同图案化的第二冲切孔。
在一些实施例中，也可以采用一冲切模具冲切光栅材料层，形成多个第一光栅211和多个第二光栅212。达到节省冲切模具效果。
本申请实施例的显示面板100的制备方法，还包括B3步骤：
依次在光栅层20上层叠设置保护层。
这样便完成了本申请实施例的显示面板100的制备过程。
在一些实施例中，光栅层20也可以采用转印的方式形成在面板主体10上。
请参照图5，在本申请第一实施例的基础上，第二实施例的显示面板100的光栅层20还包括连接体ty。在第一方向m上，连接体ty连接在相邻两个光栅21之间。连接体ty的高度小于光栅21的高度。
其中，采用较低高度的连接体ty连接在光栅21之间，当采用转印工艺时，便于光栅21脱模。另外，连接体ty也可遮挡部分的大视角的光线，进一步降低大视角的亮度。
可选的，连接体ty与光栅21同层设置且一体成型。连接体ty的材料与光栅21的材料相同。
请参照图6和图7，在第一实施例的基础上，本第三实施例的显示面板100中光栅层20的光栅21包括两种形态。
多个光栅21包括多个第一光栅211和多个第二光栅212。第一光栅211沿着第一方向m延伸。多个第一光栅211沿着第一方向m间隔排列。多个第一光栅211沿着第二方向n间隔排列。
第二光栅212沿着第二方向n延伸。多个第二光栅212沿着第一方向m间隔排列。多个第二光栅212沿着第二方向n间隔排列。
本第三实施例的显示面板100采用第一光栅211和第二光栅212配合设置，进一步减低了第一方向m的侧视亮度。
可选的，第一光栅211与第二光栅212相连。也即，一第一光栅211与一第二光栅212交叉相连。
在第一方向m上，相邻两个第一光栅211之间间隔有第一开口k1。在第二方向n上，相邻两个第二光栅212之间间隔有第二开口k2。
多个第一开口k1的至少部分沿着第二方向n形成第一光通道g1。多个第二开口k2的至少部分沿着第一方向m形成第二光通道g2。
本第三实施例的显示面板100采用第一光栅211和第二光栅212交叉相邻的设置，形成了多个第一通道g1和多个第二通道g2，使得光栅层20在第一方向m和第二方向n的侧视亮度趋于均衡。
请参照图8，本第四实施例与第一实施例的显示面板100的不同之处在于：多个光栅21包括多个第一光栅211和多个第二光栅212。第一光栅211沿着第一方向m延伸，多个第一光栅211沿着第一方向m间隔排列成第一排fp。
第二光栅212沿着第二方向n延伸，多个第二光栅212沿着第二方向n间隔排列成第二排sp。
相邻两排第一排fp之间间隔有至少一个第二光栅212。相邻两排第二排sp之间间隔有至少一个第一光栅211。
在第一方向m上，相邻两个第一光栅211之间间隔有第一开口k1。在第二方向n上，第二光栅212对应于第一开口k1设置。
在第二方向n上，相邻两个第二光栅212之间间隔有第二开口k2。在第一方向m上，第一光栅211对应于第二开口k2设置。
在第二方向n上，多个第一开口k1至少部分对应形成至少一第一光通道g1。在第一方向m上，多个第二开口k2至少部分对应形成至少一第二光通道g2。
可选的，在第一排fp和第二排sp的交叉处，第一光栅211与第二光栅212相连或间隔设置。
本第四实施例中第一光栅211和第二光栅212采用间隔设置，以增加光通道的数量。另外将第一光栅211对应于第二开口k2，第二光栅212对应于第一开口k1，提高了光线穿过光栅层20的均衡性。
在一些实施例中，第一光栅211也可以间隔设置在两个第二光栅212之间。第二光栅212可以间隔设置在两个第一光栅211之间。
可选的，本第四实施例中，在第一方向m上，第一开口k1的长度d1大于第二光栅212的宽度d2。在第二方向n上，多个第一开口k1排列形成至少一第一光通道g1。
在本第四实施例中，第一开口k1的中心和第二光栅212的中心的连线沿着第二方向n延伸在第二方向n上，多个第一开口k1形成的光通道被第二光栅212分割为两个第一光通道g1，以提高光通过的均匀性。
可选的，在第二方向n上，第二开口k2的长度d3大于第一光栅211的宽度d4。
在第一方向m上，多个第二开口k2排列形成至少一第二光通道g2。
在本第四实施例中，第二开口k2的中心和第一光栅211的中心的连线沿着第一方向m延伸。在第一方向m上，多个第二开口k2形成的光通道被第一光栅211分割为两个第二光通道g2，以提高光通过的均匀性。
可选的，第一开口k1与第二开口k2重叠形成镂空区lk。镂空区lk沿着第三方向h排列形成第三光通道g3。镂空区lk沿着第四方向j排列形成第四光通道g4。
可选的，第一开口k1和第二开口k2的尺寸相等。第一方向m、第二方向n、第三方向h和第四方向j两两相交。
可选的，第三方向h垂直于第四方向j。第一光栅211的长度等于第二光栅212的长度。第一光栅211的宽度d2等于第二光栅212的宽度d4。第一开口k1沿第一方向m的长度d1等于第一开口k1沿着第二方向n的长度。第一开口k1的长度d1等于第二开口k2的长度d3。在第一方向m上，多个第二光栅212同轴设置，多个第一光栅211同轴设置；在第二方向n上，多个第一光栅211同轴设置，多个第二光栅212同轴设置。
本第四实施例设置多个第三光通道g1和多个第四光通道g4，以增加倾斜视角的发光亮度，使得倾斜视角的亮度分别尽可能与水平视角和垂直视角的亮度一致。
请参照图9和图10，本第五实施例的显示面板100相较于第四实施例的显示面板100的不同之处在于：
第一方向m和第二方向n的夹角为钝角，比如可以是120度。且相邻两排第一排fp之间间隔有多个第二光栅212。相邻两排第二排sp之间间隔有多个第一光栅211。
相较于第四实施例的显示面板100，本第五实施例的显示面板100中光栅21的密度较稀，可提高显示面板100的发光亮度。也即，本申请的实施例可以通过调整光栅21之间的间距，进而调整显示面板100的发光亮度。
相应的，请参照图11，本申请实施例还提供一种拼接面板1000，其包括至少两个第一面板p1和至少一第二面板p2。
至少两个第一面板p1拼接设置，相邻两个第一面板p1之间存有缝隙fx。
第二面板p2设置在相邻的两个第一面板p1的出光面上，并遮挡缝隙fx。
第二面板p2为上述任意一项实施例的显示面板100。
面板主体10侧视亮度大于第一面板p1的侧视亮度。
相邻两个第一面板p1的拼接方向与第一方向m交叉设置。这样的设置以确保降低第二面板p2的侧视亮度；且在整个拼接面板1000中，保证第二面板p2的侧视亮度不为0。
可选的，第一面板p1的拼接方向垂直于第一方向m，使得部分光通道的延伸方向与拼接方向一致。
本申请实施例的拼接面板1000的第二面板p2采用光栅层20形成在面板主体10上，降低了第二面板p2的侧视亮度和正视亮度，进而使得拼接面板1000整体的侧视亮度和正视亮度分别趋于一致。
另外，需要说明的是，某一视角的侧视亮度低于阈值时，则该视角对于用户而言为不可见视角，也即在该视角下，用户不能看到面板的显示内容。因此通过减低显示面板100的侧视亮度，在一定程度上可以达到缩小视角的效果。
而第二面板p2的视角大于第一面板p1的视角，因此光栅层20的设置也达到了使得第一面板p1和第二面板p2的视角趋于一致的效果。
可选的，第一面板p1可以是液晶显示面板，但不限于此。其中，第一面板p1的出光侧还可以设置有增光膜。面板主体10包括设置在发光器件12上的彩膜层14。
在第二面板p2中形成彩膜层14可以使得第一面板p1和第二面板p2的色域趋于一致。
请参照图12，在一些实施例中，第二面板p2也可以设置在相邻的两个第一面板p1的入光面上。
需要说的是，入光面与出光面相对设置。也即出光面为第一面板p1的正面，入光面为第一面板p1的反面。
可选的，第二面板p2设置于第一面板p1的非显示区。第二面板p2对应于非显示区的部分呈透明状。
将第二面板p2设置在第一面板p1的反面，由于第一面板p1非显示区部分的膜层具有一定的耗光性，以减低第二面板p2的出光亮度，进而减少光栅层20中光栅21的设置数量，减低制备光栅层的难度。
以上对本申请实施例所提供的一种显示面板和拼接面板进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的方法及其核心思想；同时，对于本领域的技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
