具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。
为了方便理解本申请实施例提供的显示面板100，首先说明一下该显示面板100应用的场景，如图1中所示，本申请实施例提供的显示面板100应用于全面屏显示的移动终端，该移动终端为手机、平板电脑等移动终端，该全面屏在使用时，摄像头、红外传感器等不同的器件位于显示面板100的显示区域102的下方，因此，在显示面板100上设置有与该器件对应的透光区200域，该透光区200域用于透过外部照射到器件上的光线或者器件照射到移动终端外部的光线。
首先对本申请实施例中的名称进行一下说明，首先对于层结构，在本申请中所指的层结构指的是显示面板在制备时形成的不同功能的层。如下述中的第一层结构及第二层结构所指代的是显示面板中不同层，如平坦层、液晶层、黑矩阵层等不同的层结构。其次，对于通孔以及盲孔，其中，通孔指的是两端均具有开口的孔，盲孔指的是一端开口的孔。
在具体设置该显示面板100时，该显示面板100包括一个显示区域102以及非显示区域101，如图1中所示，在一些实施例中，该非显示区域101环绕该显示区域102设置，并位于显示面板100的边沿。当然，非显示区域101也不必一定环绕显示区域102设置，也可以设置在显示区域的某一侧或某两侧等。非显示区域101也可以设置为刘海形、水滴形等形状。其中，上述的显示区域102和非显示区域101指的是显示面板100的显示面上的区域。为了实现透光，在显示区域102设置了一个透光区200域，一并参考图2，该透光区200域为在显示面板100上的各个层结构上设置形成的通孔201形成的。在显示面板100中，其包含多层层结构，并且根据其透光的效果，分为两种：第一层结构及第二层结构，其中，第一层结构的透光率大于第二层结构的透光率。从而将显示面板100的层结构中，透光性能比较好的层界定成第一层结构，透光性能比较差的层结构界定成第二层结构。对于显示面板100中的层结构来说，其包含至少一个第一层结构及至少一个第二层结构，且至少一个第一层结构及至少一个第二层结构层叠设置。在排列时，上述的第一层结构及第二层结构可以交替设置时，也可以设置多个第一层结构后再设置第二层结构，具体的，可以根据实际的显示面板100的结构进行设置。
为了使得显示面板100能够具备上述的透光区域200，在设置显示面板100的各层结构时，由于第一层结构透光性能良好，因此，无需对其进行处理。而对于透光性能比较差的第二层结构进行挖孔设置，以使得光线透过。在具体设置时，在每个第二层结构上设置通孔201， 并且为了保证设置的通孔201能够穿过光线，在第二层结构为至少两个是，在设置时至少两个通孔201连通。为了清楚的描述至少两个通孔201连通的情况，下面以显示面为参考面，上述的至少两个通孔201在该参考面的垂直投影至少部分重叠，即可以采用至少两个通孔201在参考面上的垂直投影完全重叠，或者至少两个通孔201在参考面上的垂直投影中一部分重叠，并且无论时全部重叠还是部分重叠，在一个具体的实施方案中，上述的重叠部分位于显示区域102内，并且上述重叠部分的大小即为显示区域102的透光区200域的大小，当然也可以采用重叠部分位于非显示区域101，或者部分位于显示区域102，另一部分位于非显示区域101等不同方式。在光线传播时，可以穿过至少两个通孔201的重叠部分照射到器件上，同时，器件发射出的光线也可通过重叠部分照射到显示面板100外部。
如图2中所示，在具体设置上述第二层结构的通孔201时，至少两个通孔201采用共轴设置，从而可以增大上述通孔201的重叠的面积，在设置透光区200域时，可以以较小的通孔201来实现透光区200域。更具体的，各个第二层结构上的通孔201的大小及形状相同，以减少设置的透光区200域对显示面积的影响。此外，对于通孔201的形状可以为圆形、矩形、异形等不同的形状，具体的可以根据实际需要进行设置。在图1所示的通孔201采用圆形，当然也可以采用上述描述的其他的形状。
对于第二层结构来说，其可以为显示面板100上的不同功能的层结构。如在一个具体的实施方案中，该第二层结构为显示面板100上的金属层，该金属层上设置有上述的通孔201。该金属层可以为不同的个数，如一个、两个、三个等不同的个数。并且在设置时，该金属层也可以采用不同方式设置，既可以相邻设置，也可以间隔设置。如在一个具体的实施方案中，两个金属层间隔设置，且在两个金属层之间间隔一个第一层结构，该第一层结构具体为绝缘层114。而对于金属层来说，其可以为显示面板100上的不同功能的层结构，如图2所示，图2示出了两个具体的金属层为薄膜晶体管层107及栅线层108。
此外，该第二层结构还可以为其他的不同的层结构，如其中的一个第二层结构为黑矩阵109层。该黑矩阵109设置在彩膜基板上，并且黑矩阵109中对应通孔201的位置填充透明胶层。当然除了上述的黑矩阵109结构外，该第二层结构还可以为背光源，也可以为液晶层。在第二层结构为液晶层时，该液晶层内设置有用于封堵液晶的封堵结构，并且封堵结构围成位于液晶层的通孔201的侧壁，以避免液晶泄漏。
上述的第二层结构上的通孔201在形成时，直接在制备时形成。在第二层结构与第一层结构相邻时，由于第二层结构上挖去了一部分，因此，形成的第一层结构形成凸起延伸到对应的通孔201内，从而使得显示面板100中至少部分通孔201内填充有第一层结构延伸入的凸起。当然，也有部分通孔201内并未填充任何物质。
对于第一层结构来说，其为透光性能比较好的层。在显示面板100的结构中，该第一层结构可以为不同功能的结构。如第一层结构为取向膜层113、111，或者第一层结构为平坦层110，或者为位于两个金属层之间的绝缘层114，并且通过设置的绝缘层114将两个金属层分隔开来，在设置该绝缘层114时，绝缘层114延伸到栅线层108的通孔201内。
为了方便理解上述的层结构，下面以图2中示例的显示面板100的结构为例，详细说明一下整个显示面板100上的通孔201的设置方式。
如图2中所示，该显示面板100包括对盒的彩膜基板以及阵列基板，以及封闭在该彩膜基板及阵列基板的液晶层，还包括位于该液晶层两侧的取向膜层113、111，以及介于取向膜层111与彩膜基板之间的平坦层110；该显示面板100还包括位于彩膜基板背离液晶层一面 的偏光片105层以及光学胶层104，还包括设置在光学胶层104上的玻璃盖板103。除上述结构外，该显示面板100还包括设置在阵列基板背离液晶层一面的背光源117以及设置在背光源117与阵列基板之间的偏光片116。
在上述结构中，其中的背光源117、平坦层110、液晶层以及光学胶层104、偏光片105、116为第二层结构，因此，在该结构上均设置了通孔201以便于透光。其中的平坦层110为第一层结构，因此，无需进行挖孔设置。在具体设置上述液晶层时，如图2中所示，该液晶层内设置了支撑柱112，以保证彩膜基板及阵列基板在对盒后的液晶的填充空间，在形成通孔201时，在液晶层内设置封堵结构118，该封堵结构118围成通孔201的形状，并且该封堵结构118与相邻的两个层结构之间形成密封，以避免液晶泄漏，在图2所示的结构中，液晶层的两侧为取向膜层113、111，因此，设置的封堵结构118的两端分别与取向膜层113、111密封。
对于上述的阵列基板及彩膜基板，均为多层层结构，其中的一部分为透光结构，另一部分为非透光结构。首先对于阵列基板来说，其包含第一衬底115，该第一衬底115为玻璃衬底或树脂等透光材料制备而成的衬底；还包括设置在该第一衬底115上的栅线层108，以及设置在该栅线层108上的绝缘层114，该绝缘层114为透明胶层制备的绝缘层114，还包括设置在该绝缘层114上的薄膜晶体管层107，在上述层结构中，第一衬底115及绝缘层114为透光层，可以作为第一层结构。而对于薄膜晶体管层107以及栅线层108，其均为金属层，因此需要进行挖孔以形成通孔201。此外，在制备时，由于上述层结构采用一层层的制备而成，因此，在形成绝缘层114时，绝缘层114形成延伸到栅线层108的通孔201内的凸起。此外，该阵列基板还可能包含触控层，该触控层也为金属层，因此，在包含触控层时，也需要在触控层上形成通孔201，并且在制备触控层时，该触控层可能与栅线层108或者薄膜晶体管层107为同一层，或者单独设置成一层，在单独设置一层时，该触控层与栅线层108及薄膜晶体管层107之间均间隔设置。
对于彩膜基板来说，该彩膜基板包含第二衬底106，该第二衬底106也为玻璃衬底或树脂等透光材料制备而成的衬底；还包括设置在第二衬底106上的黑矩阵109，以及镶嵌在黑矩阵109内的子像素，该子像素可以为红、蓝、绿三色子像素。在上述结构中，第二衬底106为透光的，属于第一层结构，而黑矩阵109为不透光材质制备而成的，因此需要对其进行挖孔形成通孔201，并且在形成通孔201的位置不设置子像素，此外，为了形成一个稳定的支撑，该黑矩阵109上对应通孔201的位置内设置了透明胶层，该透明胶层可以通过印刷，刻蚀来实现，以保证黑矩阵层的平整度，或者如图2中所示，采用平坦层110形成向上的凸起以填充到黑矩阵层中。
此外，对于其中的取向膜层113、111，在显示面板中可以包含也可以不包含。如图2及图3中所示，图2及图3示出的显示面板取向膜113及取向膜111。在包含取向膜层113及取向膜层111时，可以根据实际的透光需要进行挖孔，如图2中所示，在需要进行挖孔时，该取向膜层113、111作为第二层结构，并对该取向膜113及取向膜111进行挖孔设置，并且在形成通孔201时，可以通过直接形成在封堵结构118的一侧，此时，封堵结构118的顶端与平坦层110直接接触。如图3所示，在不需要挖孔时，该取向膜113及取向膜111作为第一层结构，并且，取向膜113具有延伸到薄膜晶体管层107的凸起。在取向膜111不挖孔时，该封堵结构118的顶端与取向膜111进行接触。在采用该结构时，对于取向膜层的保留，保证液晶层能够取向，能够最大限度的将液晶层进行提升透过率，实验证明，在同样的成盒 条件下，有取向和没有取向，液晶层的透过率可能相差5％。除此之外，在取向膜111及取向膜113不进行挖孔时，还可采用在取向膜111及取向膜113对应通孔201的位置不进行取向处理。
一并参考图2及图3，虽然设置的通孔201在对应的第二层结构上两端开口，在多个第二层结构及第一层结构层叠时，形成的透光区200为一个盲孔的结构，如图2及图3中所示，该盲孔的开口方向朝下，并且开口朝向传感器器件。
通过上述描述可以看出，在本申请实施例提供的显示面板100中，通过在制备每层结构时，将不透光的层结构直接在制备时形成通孔201结构，并且透光的第一层结构延伸到通孔201内，从而在显示面板100制备时，直接形成带透光的通孔201，从而提高了显示面板100的制备效率，以及成品率，减少了后期挖孔对整个显示面板100造成的不良影响。
本申请实施例还提供了一种显示面板的制备方法，该制备方法包括：制备层叠的至少一个第一层结构及至少一个第二层结构；其中，所述至少一个第一层结构的透光率高于所述至少一个第二层结构的透光率；还包括：在制备第二层结构时，形成通孔。其中，在具体制备第一层结构及第二层结构时，包括制备第二层结构，在制备的第二层结构上制备第一层结构，且所述第一层结构填充到所述制备的第二层结构的通孔内。
该方法还包括：在制备第二层结构时，形成通孔；所述第一层结构的个数为至少两个，且至少两个所述通孔在所述显示面板的显示面上的垂直投影至少部分重叠。在具体形成通孔时，先制备第二层结构，在所述制备的第二层结构上刻蚀或钻孔形成通孔。
为了方便理解本申请实施例提供的上述制备方法，下面结合附图2对其具体步骤进行详细说明。
步骤一：制备背光源117；
具体的，如图4a在制备背光源117时，在背光源117上形成通孔201，其中，该背光源117中的背壳、反射板等不能反射光线的结构上开设通孔，而在背光源117中的导光部件，如导光板及膜层等结构可以作为第一层结构，不进行开孔。
步骤二、在制备的背光源上设置偏光片116。
具体的，如图4b，在背光源上设置偏光片116时，该偏光片116上设置有通孔201，并且与背光源117上的通孔201对齐。
步骤三、在偏光片116上设置阵列基板；
具体的，如图4c所示，在设置阵列基板时，包含阵列基板的制备过程，该阵列基板包括第一衬底115，该第一衬底115为玻璃衬底或树脂等透光材料制备而成的衬底，因此，无需进行挖孔。在制备时，包括在第一衬底115上制备栅线层108，具体的可以通过电镀等方式进行制备。在制备栅线层108时，由于栅线层108不透光，因此，在制备栅线层108时，通过刻蚀形成通孔201。之后，在栅线层108上制备绝缘层114，该绝缘层114为透明胶层制备的绝缘层，因此，无需进行开孔，并且绝缘层114在制备时，部分延伸到栅线层108中填充上了栅线层108上的通孔201。该方法还包括在该绝缘层114上制备薄膜晶体管层107；在制备薄膜晶体管层107时，由于其不透光，因此，在其上面应该制备通孔201，具体制备时，可以通过刻蚀的方式形成通孔201。
步骤四、在阵列基板上层叠取向膜113；
如图4d所示，在具体设置取向膜113时，该取向膜113已经进行了取向处理，并且在设置时，该取向膜113作为不透光的第二层结构，因此，需要在取向膜113上进行开孔处理， 以形成通孔201。
步骤五、在取向膜113上设置液晶层，并在液晶层上设置取向膜111；
具体的，如图4e所示，该液晶层内设置了支撑柱112，以保证彩膜基板及阵列基板在对盒后的液晶的填充空间，在形成通孔201时，在液晶层内设置封堵结构118，该封堵结构118围成通孔201的形状，并且该封堵结构118与相邻的两个层结构之间形成密封，以避免液晶泄漏。液晶层的两侧为取向膜层113、111，因此，设置的封堵结构118的两端分别与取向膜层113、111密封。在具体制备时，通过取向膜113、111以及上述中的支撑柱112及封堵结构118围成盒体，之后在其中填充液晶分子。
步骤六、在取向膜111上设置平坦层110；
具体的，如图4f所示，在取向膜111上形成平坦层110，在制备平坦层110时，在其对应透光区的位置设置一个凸起，该凸起用于与其上面的黑矩阵109配合。
步骤七、在平坦层110上设置彩膜基板；
具体的，如图4g所示，在平坦层110上设置彩膜基板，其中，彩膜基板在制备时，包括在第二衬底106上设置黑矩阵109，该黑矩阵109内镶嵌有子像素，该子像素可以为红、蓝、绿三色子像素。其中的第二衬底106为第一层结构，无需进行开孔。而黑矩阵109为不透光的第二层结构，因此，需要进行开孔，以形成通孔201，并且在形成通孔201的位置不设置子像素，此外，为了形成一个稳定的支撑，该黑矩阵109上对应通孔201的位置内设置了透明胶层，该透明胶层可以通过印刷，刻蚀来实现，以保证黑矩阵层的平整度，或者如图4g中所示，采用平坦层110形成向上的凸起以填充到黑矩阵层中。
步骤八、在彩膜基板上设置偏光片105；
具体的，如图4h，该偏光片105为不透光的第二层结构，该偏光片105上设置有通孔201。
步骤九、在偏光片105上设置玻璃盖板103；
具体的，如图4i，在偏光片105上涂覆光学胶层104，通过该光学胶层104粘接玻璃盖板103。该光学胶层104为不透光的光学胶层，因此，需要设置通孔。而玻璃盖板103为透光的，因此，无需开设通孔。
通过上述制备方法可以看出，在制备时，通过在制备每层结构时，将不透光的层结构直接在制备时形成通孔结构，从而在显示面板制备时，直接形成带透光的通孔，从而提高了显示面板的制备效率，以及成品率，减少了后期挖孔对整个显示面板造成的不良影响。
此外，本申请实施例还提供了一种移动终端，如图5所示，以手机为例，该移动终端包括上述任一项所述的显示面板100。该移动终端可以为手机或者平板电脑等常见的移动终端，并且在采用上述显示面板100时，通过在制备每层结构时，将不透光的层结构直接在制备时形成通孔结构，并且透光的第一层结构延伸到通孔内，从而在显示面板100制备时，直接形成带透光的通孔，从而提高了显示面板100的制备效率，以及成品率，减少了后期挖孔对整个显示面板100造成的不良影响。
此外，本申请还包括了一种移动终端的制备方法，如图5所示，该制备方法包括：该制备方法包括如下步骤：将上述任一项所述的显示面板装配在移动终端的壳体300上。其中显示面板的制备方法可以参考上述中的描述，在此不予赘述。在将显示面板固定在移动终端内时，可以采用现有的固定方式，如粘接或者通过螺纹连接件进行连接。在上述移动终端中，通过在制备每层结构时，将不透光的层结构直接在制备时形成通孔结构，从而在显示面板制 备时，直接形成带透光的通孔，从而提高了显示面板的制备效率，以及成品率，减少了后期挖孔对整个显示面板造成的不良影响。
以上，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以权利要求的保护范围为准。
