本申请提供显示面板，所述显示面板包括但不限于以下实施例。
在一实施例中，如图1至图3所示，所述显示面板100包括：基板10；发光层，位于所述基板10上，所述发光层包括多个发光部201，至少一所述发光部201为第一类发光部2011；色阻层，位于所述发光层远离所述基板10的一侧，所述色阻层包括与多个所述发光部201一一对应的多个色阻部301，每一所述色阻部301和对应的所述发光部201相对设置，至少一所述色阻部301为与所述第一类发光部2011相对设置的第一类色阻部3011；其中，所述第一类色阻部3011包括遮挡部401，所述遮挡部401用于阻挡光线穿过。
其中，所述基板10可以为柔性基板或者刚性基板，所述柔性基板的组成材料可以包括但不限于聚酰亚胺，所述刚性基板的组成材料可以包括但不限于玻璃。其中，多个所述发光部201可以包括但不限于发红光的红色发光部、发绿光的绿色发光部和发蓝光的蓝色发光部，发光颜色不同的发光部201的组成材料可以不同；进一步的，相邻的两所述发光部201之间可以设有一像素定义部501，像素定义部501用于阻隔相邻的两所述发光部201，以避免两者混色；进一步的，多个像素定义部501可以形成于多个发光部201之前，像素定义部501的侧部与底部的夹角可以为锐角，以便于发光部201填充于对应的两像素定义部501之间，以及降低发光部201溢出的风险。
具体的，对应于红色发光部的色阻部301可以透过的光线的波长范围包含红光的波长，对应于绿色发光部的色阻部301可以透过的光线的波长范围包含绿光的波长，对应于蓝色发光部的色阻部301可以透过的光线的波长范围包含蓝光的波长，即每一色阻部301可以透过的光线的波长范围包含对应的发光部201发出的光线的波长，并且每一发光部201发出的光线的波长处于包含于发出不同颜色的光线的发光部201对应的色阻部301可以透过的光线的波长范围之外，以避免画面显示时出现混色现象。
特别的，第一类发光部2011可以理解为发光异常的发光部201，例如第一类发光部2011实际发出的光线与理论上发出的光线的亮度差异较大，又例如第一类发光部2011一直发光无法熄灭，又例如第一类发光部2011所处区域内部分区域由于异物作用导致亮度异常。需要注意的是，由于人眼对亮点的敏感程度较高，若不对第一类发光部2011所处区域进行处理，会严重降低显示面板100的画面显示质量。
具体的，本实施例中在与第一类发光部2011相对设置的第一类色阻部3011中设置遮挡部401，且遮挡部401用于阻挡光线穿过，即第一类发光部2011发出的光线可以被对应的遮挡部401阻挡以避免入射至人眼，即第一类发光部2011所处区域呈现为常暗状态。可以理解的，由于人眼对暗点的敏感程度较低，且显示面板100在进行画面显示时，呈现为暗态的第一类发光部2011的数目极少，其它的发光部201发出的光线符合要求以使对应的区域正常显示，即人眼接收的画面中的暗点可以忽略，显示面板100的画面显示质量有所提高。
需要注意的是，通过激光作用于位于色阻层下方的导电材料时，由于部分色阻部301无法被激光穿过二造成对应区域的导电材料无法被去除，从而无法避免对应的发光部201发光，从而仍然存在亮点。结合上文论述，本实施例中通过在与第一类发光部2011相对设置的第一类色阻部3011中设置遮挡部401以阻挡第一类发光部2011发出的光线穿过，即本实施例中的遮挡部401并不是位于第一类色阻部3011靠近发光层的一侧，避免了采用激光通过穿透色阻部301的方式以实现消除亮点，提高了像素修复的成功率。
在一实施例中，如图1至图3所示，所述遮挡部401位于对应的所述第一类色阻部3011远离所述发光层的区域内。可以理解的，本实施例的第一类色阻部3011内，遮挡部401靠近显示面板100的出光侧而设置，可以在靠近出光侧的区域进行光线的消除，避免遮挡部401由于设置为出光侧距离较远而需进行二次消除光线，提高了光线消除的可靠性。具体的，可以采用激光从显示面板100的出光侧照射至第一类色阻部3011，以作用于第一类色阻部3011靠近显示面板100的出光侧的部分，以将第一类色阻部3011靠近显示面板100的出光侧的部分转化为遮挡部401。
在一实施例中，所述遮挡部401的组成材料包括碳元素。其中，色阻部301的组成材料可以为有机材料，即色阻部301的组成材料可以包括碳元素、氧元素和氢元素，结合上文论述，采用激光从显示面板100的出光侧照射至第一类色阻部3011，可以使得第一类色阻部3011靠近显示面板100的出光侧的部分发生炭化作用，可以理解为第一类色阻部3011靠近显示面板100的出光侧的部分中的氧元素和氢元素变成气态而脱离于第一类色阻部3011，以使第一类色阻部3011靠近显示面板100的出光侧的部分中仅包括碳元素形成为遮挡部401，可以理解为遮挡部401包括由碳元素形成的呈黑色的多个颗粒，因此遮挡部401可以阻挡第一类发光部2011发出的光线穿过以使对应的区域呈现为暗态，从而实现对应的子像素的修复。
在一实施例中，如图1至图3所示，所述显示面板100还包括：黑色矩阵层，与所述色阻层同层设置，所述黑色矩阵层包括多个黑色矩阵部601，所述黑色矩阵部601的侧部与底部的夹角为锐角，相邻两所述黑色矩阵部601之间填充有一所述色阻部301；其中，如图1所示，所述遮挡部401中每一侧部与相邻的所述黑色矩阵部601中相邻的侧部共面。
需要注意的是，如图1至图3所示，黑色矩阵部601的侧部与底部的夹角为锐角，结合上文关于像素定义部501的论述，黑色矩阵部601可以阻隔相邻的两色阻部301以避免两者混色。结合上文论述，每一色阻部301可以透过的光线的波长范围包含对应的发光部201发出的光线的波长，并且每一发光部201发出的光线的波长处于包含于发出不同颜色的光线的发光部201对应的色阻部301可以透过的光线的波长范围之外，本实施例中的黑色矩阵部601位于相邻两色阻部301之间，黑色矩阵部601可以吸收任意颜色的光线，即多个色阻部301所在的区域为透光区，可以透过对应颜色的光线，进一步的，黑色矩阵部601的侧部与底部的夹角为锐角，即对应的透光区也呈现为开口逐渐增大，有效增加了出光面积。
在此基础上，如图1所示，本实施例中的遮挡部401中每一侧部与相邻的黑色矩阵部601中相邻的侧部共面，即遮挡部401可以形成为对应的第一类色阻部3011远离发光层的一侧，也可以阻挡经由第一类色阻部3011的侧部射出的光线；可以理解的，当第一类发光部2011整体发光异常时，本实施例可以实现对于第一类发光部2011发出的光线的全面阻挡，提高了对应的子像素的修复的可靠性。
在一实施例中，如图2所示，所述第一类发光部2011包括异常区域A，所述遮挡部401与对应的所述第一类发光部2011中的所述异常区域A相对设置。其中，结合上文论述，异常区域A可以理解为第一类发光部2011所处区域内由于异物作用导致亮度异常的部分区域，即第一类发光部2011中除去异常区域A之外的区域可以正常发光。可以理解的，本实施例中的遮挡部401仅与对应的第一类发光部2011中的异常区域A相对设置，而并未与整个第一类发光部2011相对设置，一方面，第一类发光部2011中除去异常区域A之外的区域中的部分发出的光线仍然可以透过第一类色阻部3011中除去遮挡部401的部分射出以削减暗点的尺寸，另一方面，结合上文论述，此处可以仅对第一类色阻部3011中与对应的第一类发光部2011中的异常区域A相对设置的部分进行碳化处理，减小了激光作用的范围，可以有效节能或者提高像素修复发效率。
在一实施例中，如图1至图3所示，所述显示面板100还包括：阳极层，位于所述发光层靠近所述基板10的一侧，所述阳极层包括与多个所述发光部201一一对应的多个阳极部701；阴极层80，位于所述发光层远离所述基板10的一侧，如图1和图2所示，所述阴极层80至少覆盖所述第一类发光部2011远离所述基板10的一侧。
其中，每一阳极部701可以具有对应的阳极电压，整层的阴极层80可以具有阴极电压，对于位于阳极部701和阴极层80之间的发光部201而言，在对应的阳极电压和阴极电压的作用下，电子从阴极层80注入到发光部201中，同时空穴从阳极部701注入到发光部201中，从而在电子和空穴在发光部201中发生复合而发出光。进一步的，如图1至图3所示，所述显示面板100还包括位于基板10和阳极层之间的线路层90，线路层90可以包括传递栅极信号的多条栅极线、传递数据信号的多条数据线和多个驱动晶体管，多个薄膜晶体管和多个发光部201一一对应，且每一薄膜晶体管和对应的发光部201相对设置且电性连接对应的阳极部701，多条栅极线和多条数据线相交设置以形成多个单位区域，每一个驱动晶体管位于对应的单位区域内；具体的，每一薄膜晶体管电性连接至对应的栅极线和对应的数据线以向对应的阳极部701输入相应的信号，从而控制对应的发光部201发光。
可以理解的，由于发光异常的发光部201的不确定性，在进行像素修复之前可以形成整层的阴极层80，结合上文论述，本申请中再根据第一类发光部2011的位置对对应的第一类色阻部3011处理以形成遮挡部401，从而阻挡第一类发光部2011发出的光线射出与出光侧，在此基础上，本实施例中限定阴极层80至少覆盖第一类发光部2011远离基板10的一侧，即本实施例不需要对阴极层80中与第一类发光部2011相对设置的部分进行处理而阻止第一类发光部2011发光。因此，一方面，本实施例避免了去除阴极层80中与第一类发光部2011对应的部分，结合上文论述，本实施例可以降低由于激光无法透过一些发光部201而作用于阴极层80中对应的部分造成的亮点无法去除的风险，提高了像素修复的成功率；另一方面，当仅对第一类色阻部3011中与对应的第一类发光部2011中的异常区域A相对设置的部分进行碳化处理时，由于阴极层80覆盖第一类发光部2011远离基板10的一侧，使得第一类发光部2011仍然可以发光，并且第一类发光部2011中除去异常区域A之外的区域中的部分发出的光线仍然可以透过第一类色阻部3011中除去遮挡部401的部分射出以削减暗点的尺寸。
在一实施例中，如图3所示，至少一所述发光部201为第二类发光部2012，所述阴极层80设有至少一开口801，所述开口801和所述第二类发光部2012相对设置。其中，第二类发光部2012也可以理解为发光异常的发光部201，可以参考上文关于第一类发光部2011的相关描述，第二类发光部2012发光的颜色和第一类发光部2011发光的颜色可以相同或者不同。
可以理解的，对应于不同颜色的发光部201的色阻部301对于光线的穿透率分布存在差异，此处以对应于红色发光部的红色色阻部、对应于绿色发光部的绿色色阻部、对应于蓝色发光部的蓝色色阻部对于光线的穿透率分布如图4所示为例进行说明，红色色阻部对于波长大于650纳米的光线的透过率可以大概达到70%甚至以上，绿色色阻部对于波长为500纳米至570纳米的光线、波长大于750纳米的光线透过率可以大概达到40%甚至以上，蓝色色阻部对于波长为420纳米至500纳米的光线、波长大于850纳米的光线的透过率可以大概达到40%甚至以上。
具体的，结合图3和图4所示，当第一类色阻部3011为红色色阻部、绿色色阻部、蓝色色阻部三者中的任一者时，由于红色色阻部、绿色色阻部、蓝色色阻部三者中的任一者对于波长小于350纳米的光线的透光率均极低，即对应为吸收率均极高，可以理解为波长小于350纳米的光线可以充分作用于红色色阻部、绿色色阻部、蓝色色阻部三者中的任一者以发生炭化作用，因此均可以采用波长小于350纳米的激光处理第一类色阻部3011以形成遮挡部401。
其中，如图1至图3所示，显示面板100还可以包括位于色阻层和黑色矩阵层远离基板10的一侧的平坦层901，平坦层901远离基板10的一侧可以平行于水平面以实现平坦化。其中，本实施例中的第二类发光部2012可以理解为采用去除对应的阴极的方式实现避免第二类发光部2012发光。
具体的，结合图3和图4所示，为避免激光的穿透率过高会损坏位于色阻层上的平坦层901等膜层，当第二类发光部2012为红色发光部时，可以采用但不限于波长为650纳米至750纳米的激光穿透对应于第二类发光部2012的色阻部301，即采用但不限于波长为650纳米至750纳米的激光穿透此红色色阻部处理阴极层80以形成对应的开口801，当第二类发光部2012为绿色发光部时，可以采用但不限于波长为520纳米至550纳米的激光穿透对应于第二类发光部2012的色阻部301，即采用但不限于波长为520纳米至550纳米的激光穿透此绿色色阻部处理阴极层80以形成对应的开口801，当第二类发光部2012为蓝色发光部时，可以采用但不限于波长为420纳米至490纳米的激光穿透对应于第二类发光部2012的色阻部301，即采用但不限于波长为420纳米至490纳米的激光穿透此蓝色色阻部处理阴极层80以形成对应的开口801。
在一实施例中，如图4所示，与发光颜色不同的多个所述发光部一一对应的多个色阻部，对于波长大于850纳米的光线的穿透率均大于60%。具体的，结合图4和上文描述可知，红色色阻部对于波长大于650纳米的光线的透过率可以大概达到70%甚至以上，绿色色阻部对于波长大于750纳米的光线透过率可以大概达到40%甚至以上，蓝色色阻部对于波长大于850纳米的光线的透过率可以大概达到40%甚至以上，在此基础上，如图4所示，本实施例中的红色色阻部、绿色色阻部和蓝色色阻部三者对于波长大于850纳米的光线的穿透率可以均大于60%。因此，在保证位于色阻层上的平坦层901等膜层不被烧伤的前提下，也可以均采用波长大于850纳米的激光穿透红色色阻部、绿色色阻部或者蓝色色阻部在阴极层80中对应的区域以形成对应的开口801。
在一实施例中，如图1至图3所示，所述显示面板100还包括：触控层902，位于所述色阻层靠近所述发光层的一侧，所述触控层902包括多条触控电极9021，所述触控电极9021位于相邻的两所述发光部201之间。其中，触控层902可以实现触控功能，多条触控电极9021可以包括多条发射电极和多条接收电极，发射电极可以传输触控发射信号以驱动接收电极工作，接收电极可以在外界触摸下产生触控感应信号。可以理解的，本实施例中的触控层902可以电容触控层而并非光学触控层，以避免受到遮挡部401的影响，进一步的，触控电极9021位于相邻的两发光部201之间，可以降低触控层902对于发光部201发出的光线的影响。进一步的，触控电极9021的组成材料可以包括氧化铟锡，进一步降低触控层902对于发光部201发出的光线的影响。
本申请还提供移动终端，所述移动终端包括终端主体部和如上文任一所述的显示面板，所述终端主体部和所述显示面板组合为一体。
本申请还提供显示面板的制作方法，如图5所示，所述显示面板的制作方法可以包括但不限于以下步骤，并且结合图6的场景示意图作为参考。
S1，提供一基板。
其中，如图6所示，所述基板10可以为柔性基板或者刚性基板，所述柔性基板的组成材料可以包括但不限于聚酰亚胺，所述刚性基板的组成材料可以包括但不限于玻璃。
S2，在所述基板上形成发光层，所述发光层包括多个发光部，至少一所述发光部为第一类发光部。
其中，如图6所示，多个所述发光部201可以包括但不限于发红光的红色发光部、发绿光的绿色发光部和发蓝光的蓝色发光部，发光颜色不同的发光部的组成材料可以不同；进一步的，相邻的两所述发光部201之间可以设有一像素定义部501，像素定义部501用于阻隔相邻的两所述发光部201，以避免两者混色；进一步的，多个像素定义部501可以形成于多个发光部201之前，像素定义部501的侧部与底部的夹角可以为锐角，以便于发光部201填充于对应的两像素定义部501之间，以及降低发光部201溢出的风险。
特别的，第一类发光部2011可以理解为发光异常的发光部，例如第一类发光部2011实际发出的光线与理论上发出的光线的亮度差异较大，又例如第一类发光部2011一直发光无法熄灭，又例如第一类发光部2011所处区域内部分区域由于异物作用导致亮度异常。需要注意的是，由于人眼对亮点的敏感程度较高，若不对第一类发光部2011所处区域进行处理，会严重降低显示面板的画面显示质量。
具体的，如图6所示，在形成多个像素定义部501之前，可以依次在基板10上形成线路层90、位于线路层90上的多个阳极部701，线路层90和多个阳极部701的具体设置方式可以参考上文的相关描述。
S3，在所述发光层远离所述基板的一侧形成色阻层，所述色阻层包括与多个所述发光部一一对应的多个色阻部，每一所述色阻部和对应的所述发光部相对设置，至少一所述色阻部为与所述第一类发光部相对设置的第一类色阻部，所述第一类色阻部包括遮挡部，所述遮挡部用于阻挡光线穿过。
具体的，如图6所示，每一色阻部301可以透过的光线的波长范围包含对应的发光部201发出的光线的波长，并且每一发光部201发出的光线的波长处于发出不同颜色的光线的发光部201对应的色阻部301可以透过的光线的波长范围之外，以避免画面显示时出现混色现象。
可以理解的，本实施例中在与第一类发光部2011相对设置的第一类色阻部3011中设置遮挡部401，且遮挡部401用于阻挡光线穿过，即第一类发光部2011发出的光线可以被对应的遮挡部401阻挡以避免入射至人眼，即第一类发光部2011所处区域呈现为常暗状态。可以理解的，由于人眼对暗点的敏感程度较低，且显示面板在进行画面显示时，呈现为暗态的第一类发光部2011的数目极少，其它的发光部201发出的光线符合要求以使对应的区域正常显示，即人眼接收的画面中的暗点可以忽略，显示面板的画面显示质量有所提高。并且，本实施例中通过在与第一类发光部2011相对设置的第一类色阻部3011中设置遮挡部401以阻挡第一类发光部2011发出的光线穿过，可以避免采用激光通过穿透色阻部301的方式以实现消除亮点，提高了像素修复的成功率。
具体的，如图6所示，在形成色阻层之前，可以依次在发光层上形成阴极层80、位于阴极层80上的触控层902、位于触控层902上的多个黑色矩阵部601，触控层902包括多条触控电极9021，在形成色阻层之后，可以在色阻层和多个黑色矩阵部601上形成平坦层901，阴极层80、触控层902、黑色矩阵部601、触控电极9021的具体设置方式可以参考上文的相关描述。
其中，在步骤S3中形成所述第一类色阻部的步骤，可以包括但不限于如下步骤，并且结合图7的场景示意图作为参考。
S301，在所述第一类发光部远离所述基板的一侧形成第一类色阻块。
具体的，如图7所示，此处可以理解为在第一类发光部2011远离基板10的一侧形成多个色阻块702，多个色阻块702用于形成多个色阻部301，其中多个色阻块702还用于形成包括遮挡部401的色阻块称之为第一类色阻块7021，即每一色阻块702的组成材料可以相同于对应的色阻部301中除去遮挡部401之外的部分的组成材料。
S302，自所述第一类色阻块远离所述基板的一侧采用激光处理所述第一类色阻块，以在所述第一类色阻块内形成所述遮挡部。
具体的，如图7所示，可以采用激光照射第一类色阻块7021远离基板10的一侧以进行炭化处理，其中用于进行炭化处理的激光的选择可以参考上文中结合图4的相关描述。具体的，激光的能量、照射时间以及照射区域可以根据实际情况进行选择，应该避免灼伤位于色阻层上的平坦层901等膜层。
其中，结合上文论述，第一类色阻块7021经由炭化处理可以形成包括遮挡部401的第一类色阻部3011，未经由碳化处理的多个色阻块702保留作为多个色阻部301。当然，结合上文论述，炭化处理可以在形成平坦层901之后进行。
本申请提供了显示面板及其制作方法、移动终端，所述显示面板包括：基板；发光层，位于所述基板上，所述发光层包括多个发光部，至少一所述发光部为第一类发光部；色阻层，位于所述发光层远离所述基板的一侧，所述色阻层包括与多个所述发光部一一对应的多个色阻部，每一所述色阻部和对应的所述发光部相对设置，至少一所述色阻部为与所述第一类发光部相对设置的第一类色阻部；其中，所述第一类色阻部包括遮挡部，所述遮挡部用于阻挡光线穿过。其中，本申请通过将第一类色阻部设置为包括用于阻挡光线穿过的遮挡部，以实现阻挡第一类色阻部发出的光线穿过的作用，避免了采用激光通过穿透色阻部的方式以实现消除亮点，提高了像素修复的成功率。
