本申请提出一种显示面板100。
参照图1至图3,本申请技术方案提出的显示面板100包括有效显示区和邻近所述有效显示区的非有效显示区,该显示面板100还包括:
衬底基板10;
第一金属层30,所述第一金属层30设置于所述衬底基板10的一表面,定义所述第一金属层30沿第一方向投影于所述衬底基板10第一投影区;
第二金属层50,所述第二金属层50设置于所述第一金属层30的正上方,定义所述第二金属层50沿第一方向投影于所述衬底基板10设置第二投影区;
所述第二投影区的外轮廓设置于所述第一投影区的外轮廓内;
所述第一金属层30和所述第二金属层50均设置于所述非有效显示区。
本申请技术方案通过将显示面板100的第二金属层50设于第一金属层30的一侧,定义所述第一金属层30沿第一方向投影于所述衬底基板10形成第一投影区;定义所述第二金属层50沿第一方向投影于所述衬底基板10形成第二投影区;所述第二投影区的外轮廓设置于所述第一投影区的外轮廓内,从而为堆叠于第一金属层30上方的第二金属层50设置第二绝缘层90提供更多覆盖的空间,使得第二绝缘层90覆盖第二金属层50时具有较大的缓冲空间,进而避免了第二绝缘层90不能将第二金属层50的边缘覆盖的问题。并且,由于将第一金属层30和第二金属层50均设于非有效显示区,如此设置可以避免金属层遮挡有效显示区的光传播,进而提高显示面板100的产品质量。如此,本申请技术方案可以保证绝缘层对双层金属层进行覆盖时,密封性较好,从而避免上层金属层被腐蚀,提高产品质量。
在本申请的一实施例中衬底基板10可以包括例如玻璃材料、金属材料或塑料材料(如聚对苯二甲酸乙二醇醋(PET,Polyethylene terephthalate)、聚萘二甲酸乙二醇醋、聚酰亚胺)的各种材料中的一种或多种设置的基底。衬底基板10可以包括设置在基底上的TFT阵列。衬底基板10可以是可弯曲的或可折叠的。
以及绝缘层的材料可以为含硅有机材料,含硅光刻胶可为主链含硅、以硅氧键作为主链或含硅的光刻胶材料例如含硅聚酰亚胺或聚二甲基硅氧烷类材料,更可选地,可采用含硅聚酰亚胺,含硅聚酰亚胺为有机高分子材料,覆盖性及弯折性好,适用范围广。
在本申请的一实施例中,第一金属层30和第二金属层50均用于共电极信号,绝缘层未被第一金属层30和第二金属层50覆盖的部分可以用于局部透光。以及,该第一金属层30和第二金属层50的材质可以采用铜、铝、钼或者其他合金,只要均有较好地导电性即可。
需要说明的是,该第二投影区的外轮廓设置于第一投影区的外轮廓的形式可以为“回”字型的完全包含,或者为“目”字型的部分包含(该第二投影区的部分外轮廓可以与第一投影区的部分外轮廓重合,该第二投影区其他部分的外轮廓则设置于第一投影区的其他部分的外轮廓内),具体根据产品的实际结构设置,只要能使第二金属层50设置让位绝缘层铺设的位置即可。以及,该第一方向具体为上下方向或者为第一金属层30、第二金属层50、第一绝缘层70和第二绝缘层90的堆叠方向。
在本申请的一实施例中,非有效显示区呈环形设置,并环绕有效显示区,如此设置便于第一金属层30和第二金属层50的设置,进而便于共电极信号的传输。
在本申请的一实施例中,所述第一投影区的外轮廓为矩形;
且/或,所述第二投影区的外轮廓为矩形。如此设置,其结构简单、易于制造,当然了,具体应用中,第一投影区和第二投影区的外轮廓也可设为其它形状,例如弧形或者环形或者其它多边形等。
参照图1、图2,在本申请的一实施例中,所述第一金属层30具有相邻设置的第一边缘31和第二边缘33,所述第二金属层50在第二边缘33之延伸方向的投影尺寸小于所述第二边缘33。第二边缘33的延伸方向即为第一金属层30的宽度方向,即第二金属层50的宽度小于第一金属层30的宽度,可以理解的是,在本实施例中,第一边缘31为第一金属层30长度较长的边缘,第二边缘33为第一金属层30长度较短的边缘,该第二边缘33的长度为1μm-100μm,如此设置一方面能较好地便于共电极信号的传输,另一方面较好地防止第一金属层30的尺寸不至于过大而影响显示面板100的整体结构。具体的,该第二边缘33的取值可以为3μm、7μm、10μm、20μm、30μm、40μm、50μm、60μm、70μm、80μm、90μm等均能较好的便于共电极信号的传输。可选的,该第二边缘33的长度为5μm-20μm,如此设置可一方面能很好地便于共电极信号的传输,另一方面很好地防止第一金属层30的尺寸不至于过大而影响显示面板100的整体结构。具体的,该第二边缘33的取值可以为8μm、9μm、12μm、15μm、17μm、18μm等均能很好的便于共电极信号的传输。
第二绝缘层90沿第二金属层50的宽度方向铺设,由于第二金属层50内缩设置让位第二绝缘层90堆叠的空间,第二绝缘层90可以在第二金属层50的边界处得到缓冲,从而第二绝缘层90不至于因为较大的爬坡而不能将第二金属层50的边界覆盖。第一边缘31即为第一金属层30的长度,可以理解的是,当第一金属层30投影于衬底基板10,且第一金属层30呈矩形设置时,该第一金属层30具有两相对的第一边缘31和两相对的第二边缘33。
在本申请的一实施例中,所述第二金属层50在所述第二边缘33之延伸方向的投影尺寸分别与所述第二边缘33的两端部设置距离x1 和距离x2 ,所述距离x1 的取值范围为:0<x1 ≤50μm;
所述距离x2 的取值范围为:0<x2 ≤50μm。
在本实施例中,第一金属层30和第二金属层50用于共电极信号的传输(类似于地线Ground,只是数值不一定为0),当x1 =0时,该第二金属层50在第二边缘33之延伸方向的投影尺寸与第二边缘33的长度相等,由于第二金属层50设置在第一金属层30上,所以第二金属层50的边缘处设置较大的断差,较大的断差会导致第二绝缘层90铺设时,在第二金属层50的边缘处的爬坡度太大,不利于对第二金属层50进行覆盖。当x1 >50μm时,该第二金属层50在第二边缘33之延伸方向的投影尺寸与第二边缘33的长度具有太长的让位缓冲部分,从而第二金属层50的尺寸会变得太小,太小的第二金属层50不利于传输足够的共电极信号,从而不利于显示面板100正常工作。当x1 为:0<x1 ≤50μm时,一方面可以使第二金属层50的边缘相对第一金属层30内缩设置一定的让位缓冲,另一方面不至于使第二金属层50的尺寸过小而无法传输足够的共电极信号,方便用户使用。x2 的设置的效果与x1 的设置效果近似,在此不做赘述。可以理解的是,该x1 和x2 可以为1μm、3μm、5μm、10μm、15μm、20μm、25μm、30μm、35μm、40μm、45μm、50μm等,均可使第二绝缘层90铺设于第二金属层50上的覆盖性较好。
在本申请的一实施例中,所述距离x1 的取值范围为:3≤x1 ≤30μm;
且/或,所述距离x2 的取值范围为:3≤x2 ≤30μm。如此设置,一方面可以很好的使第二金属层50的边缘相对第一金属层30内缩设置一定的让位缓冲,另一方面很好的使第二金属层50的尺寸不至于过小而无法传输足够的共电极信号,方便用户使用。
参照图1,在本申请的一实施例中,所述显示面板100还包括:
第一绝缘层70,所述第一绝缘层70设于所述衬底基板10的一表面,并将覆盖所述第一金属层30,所述第二金属层50设于所述第一绝缘层70背离所述第一金属层30的表面;
第二绝缘层90,所述第二绝缘层90设于所述第一绝缘层70背离所述衬底基板10的表面,并将覆盖所述第二金属层50。
在本申请的一实施例中,可以在第一金属层30上,例如通过旋涂或丝网印刷,施加含硅聚酰亚胺设置用于绝缘的第一绝缘层70和/或第二绝缘层90。根据需要,可以对第一绝缘层70和/或第二绝缘层90进行图案化。采用含硅光刻胶设置的第一绝缘层70和/或第二绝缘层90,可通过一次光刻工艺对绝缘层进行图案化。与采用无机材料例如氧化硅、碳化硅作为第一绝缘层70和/或第二绝缘层90和常规绝缘层的工艺相比,减少了图案转移和光刻胶剥离的步骤,可以提高产品质量和成品率。
参照图1,在本申请的一实施例中,所述第二金属层50包括第一表面、第二表面以及连接所述第一表面和所述第二表面的侧面51,所述侧面51与所述第二表面呈夹角设置。该第一表面和第二表面分别为第二金属层的上表面和下表面,将第二金属层50的侧面51与第二表面设置夹角可以增加第二绝缘层90与第二金属层50的接触面积,从而提高第二绝缘层90对第二金属层50的覆盖性。同样的,可以对第一金属层30的侧面51也采用与第一金属层30的底面具有夹角的设置,提高第一绝缘层70的覆盖性。
本申请还提出一种显示装置,该显示装置包括显示面板100,该显示面板100包括衬底基板10;第一金属层30,所述第一金属层30设置于所述衬底基板10的一表面,定义所述第一金属层30沿第一方向投影于所述衬底基板10形成第一投影区;
第二金属层50,所述第二金属层50设置于所述第一金属层30的一侧,定义所述第二金属层50沿第一方向投影于所述衬底基板10形成第二投影区;
所述第二投影区的外轮廓设置于所述第一投影区的外轮廓内;
所述第一金属层30和所述第二金属层50均设置于所述非有效显示区。由于本显示装置采用了上述所有实施例的全部技术方案,因此至少具有上述实施例的技术方案所带来的所有效果,在此不再一一赘述。
以上所述仅为本申请的可选实施例,并非因此限制本申请的专利范围,凡是在本申请的发明构思下,利用本申请说明书及附图内容所作的等效结构变换,或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
