本发明的最佳实施方式
以下各实施例的说明是参考附加的图式,用以例示本揭示可用以实施的特定实施例。
在本揭示的实施例中,如图1所示,图1为本揭示实施例的显示面板结构示意图。所述显示面板包括:薄膜晶体管基板100、彩色滤光片基板101、第一金属图案102以及第二金属图案103,薄膜晶体管基板100与彩色滤光片基板101相对设置,第一金属图案102与第二金属图案103设置在所述薄膜晶体管基板100上,同时,所述显示面板还包括第一区域104、第二区域105以及第三区域106,第一区域104与第二区域105相邻,第二区域105与第三区域106相邻。具体的,在第一区域104内,为印刷线路区,在所述区域内,薄膜晶体管基板100与侧边的柔性电路板相连接,柔性电路板上设置有侧边印刷线路,柔性电路板上的侧边印刷线路与薄膜晶体管基板100上的第二金属图案相匹配,以实现显示面板的显示功能,同时,在印刷线路的边缘区域内还设置有对位标尺,所述对位标尺包括有多个平行排布的对位刻度。第二区域105为标记对位区,具有定位的作用,第三区域106为精度监控区,在具体监控时,通过比对金属图案与对位标尺的吻合程度来判断所述印刷电路的生产精度。
实际生产监控过程中,由于印刷线路层细小精密,其制造精度难以监控,进而影响显示面板的显示性能。在本揭示实施例中,通过在显示面板的第三区域106内设置第一金属图案102,若干第一金属图案102间隔设置,每相邻两条第一金属图案102之间的距离相同,所述第一金属图案102为条状金属图案,以方便与标记刻度进行比对,提高辨识率。第二金属图案103设置在薄膜晶体管100上,每相邻两条第二金属图案103之间的距离相同,第二金属图案103与柔性电路板上的印刷电路匹配。
具体的,在进行精度监控时,第二金属图案103为主刻度,第一金属图案102为分刻度,其中,第二金属图案103的宽度大于第一金属图案102的宽度,第一金属图案102与第二金属图案103相结合,形成一种游标卡尺,其中,第一金属图案102为游标卡尺上的分刻度,第二金属图案103为游标卡尺上的主刻度。监控时,首先将印刷线路区内的一条印刷线路与对位标尺的主刻度对齐,对齐后,再比对第三区域106内的第一金属图案102中的金属图案,找出与标准刻度对齐情况最一致的金属图案,然后直接从标准刻度上读出该条金属图案所对应的精度,从而监控得到所述印刷电路的制造精度。
如图2所示,图2为本揭示另一实施例的显示面板结构示意图。所述显示面板包括:薄膜晶体管基板200、彩色滤光片基板201、第一金属图案202、第二金属图案203以及金属层204。薄膜晶体管基板200与彩色滤光片基板201相对设置,第一金属图案202与第二金属图案203设置在薄膜晶体管基板200上,并设置在第二区域206内,第二金属图案203设置在第一金属图案202上,金属层204设置在第一区域205内,并与侧边印刷线路连接。
第一金属图案202的金属层较薄,正常情况下不容易辨识,在精度监控时,难以区分,因此,在第一金属图案202上再设置第二金属图案203,使分刻度为双层金属图案,以提升识别度,防止在比对时,读数错误。第二金属图案203的厚度与第一金属图案202的厚度相同,并与第一金属图案202一一对应,同时,第一金属图案202和第二金属图案203的总厚度小于薄膜晶体管基板200与彩色滤光片基板201之间的距离。
如图3所示,图3为本揭示又一实施例提供的显示面板的结构示意图。所示显示面板包括:薄膜晶体管基板300、彩色滤光片基板301、第一金属图案302、黑矩阵303、开口304以及第二金属图案305,同时,还包括相邻设置的第一区域306与第二区域307。薄膜晶体管基板300与彩色滤光片基板301相对设置,第一金属图案302与第二金属图案305设置在薄膜晶体管基板300上,黑矩阵303设置在薄膜晶体管基板300与彩色滤光片基板301之间。
为了提高精度监控时的刻度识别度,本实施例中,在黑矩阵303上开设若干开口304,所述开口304与第一金属图案302相对,这样,当从侧边进行监控时,容易对第一金属图案302和标准刻度进行比对,从而提高了金属层的识别度。同时,还可在开口304的区域上设置支撑柱,以进一步的提高辨识度。
具体的,在进行精度监控时,如图4所示,图4为本揭示实施例提供的对位标尺示意图。对位标尺包括第一区域400、第二区域401以及第三区域402,上述区域依次相邻设置,同时,在第一区域400内还包括主刻度403,在第三区域402内设置有分刻度404。对位刻度的精度等级设置在分刻度404上,每两个相邻分刻度的偏差介于1um~4um之间,并且,分刻度404设置有刻度零点,多个对位刻度对称分布在所述刻度零点的两侧,沿所述刻度零点向其两侧,刻度值依次增大。
优选的,分刻度404的精度等级设置为5级,在精度监控时,比对金属图案层与分刻度的对齐情况,金属图案层与哪一条分刻度相对齐,该条分刻度代表的精度等级即为印刷线路的印刷精度。同时,根据具体的印刷线路产品,分刻度404的精度等级还可设置更多等级。
如图5所示,图5为本揭示实施例提供的显示面板的印刷线路精度监控流程图。具体的,包括如下步骤:
S100:提供一待监控的显示面板以及具有标记刻度的掩膜板。
显示面板内的金属图案及印刷线路印刷完成后,对其精度进行监控,所述掩膜板上设置有对位标尺,所述对位标尺包括主刻度以及分刻度。在进行精度监控时,将不同的刻度与显示面板上的金属图案相对齐。
S101:将所述掩膜板的主刻度与所述显示面板的印刷线路对齐;
首先将掩膜板的主刻度与显示面板侧边的印刷线路金属层相对齐,主刻度相当于游标卡尺的主刻度。
S102:观察所述掩膜板的分刻度与所述显示面板的金属图案,找出所述金属图案与所述分刻度对齐的刻度值,并标记。
分刻度设置在精度监控区内,分刻度代表了印刷线路的印刷等级,在精度监控时,从金属图案中找出一条金属图案,所述金属图案与分刻度对齐程度最高,其对齐的该分刻度等级即为印刷线路的印刷精度等级。
S103:根据所述步骤S102的读数,监控所述印刷线路的精度。
综上所述,整个流程可通过显微镜从显示面板的侧面印刷线路区进行观察,直接从分刻度上读取印刷线路的印刷等级,操作流程简单。
以上对本揭示实施例所提供的一种显示面板及显示面板的印刷线路的精度监控的方法进行了详细介绍,以上实施例的说明只是用于帮助理解本揭示的技术方案及其核心思想;本领域的普通技术人员应当理解:其依然可以对前述各实施例所记载的技术方案进行修改,而这些修改或者替换,并不使相应技术方案的本质脱离本揭示各实施例的技术方案的范围。
