Description

一种显示面板和显示装置
技术领域
本发明涉及显示技术领域,更具体的说,涉及一种显示面板和显示装置。
背景技术
显示器具有机身薄、省电、无辐射等众多优点,得到了广泛的应用。现有市场上的显示器大部分为背光型显示器,其包括显示面板及背光模组(backlight module)。显示面板的工作原理是在两片平行的基板当中放置液晶分子,并在两片基板上施加驱动电压来控制液晶分子的旋转方向,以将背光模组的光线折射出来产生画面。
其中,薄膜晶体管显示器(Thin Film Transistor-Liquid Crystal Display,TFT-LCD)由于具有低的功耗、优异的画面品质以及较高的生产良率等性能,目前已经逐渐占据了显示领域的主导地位。同样,薄膜晶体管显示器包含显示面板和背光模组,显示面板包括彩膜基板(Color Filter Substrate,CF Substrate,也称彩色滤光片基板)和薄膜晶体管阵列基板(Thin Film Transistor Substrate,TFT Substrate),上述基板的相对内侧存在透明电极。两片基板之间夹一层液晶分子(Liquid Crystal,LC)。显示面板是通过电场对液晶分子取向的控制,改变光的偏振状态,并藉由偏光板实现光路的穿透与阻挡,实现显示的目的。
彩色光阻设置在阵列基板(Color Filter On TFT,COT)的技术近年来被广泛的应用于薄膜晶体管显示器产品上,其工艺有利于大尺寸及曲面式显示器应用的发展。
在COT技术于薄膜晶体管阵列基板工艺中,金属层容易断线,进而造成基板报废,增加报废成本。
发明内容
本发明所要解决的技术问题是提供一种减少金属层断线,提高良品率的显示面板。
此外,本发明还提供一种包括以上所述显示面板的显示装置。
本发明的目的是通过以下技术方案来实现的:一种显示面板,其特征在于,所述显示面板包括:
基板;
主动开关阵列;
彩色光阻层,形成于主动开关阵列上;
所述主动开关阵列,包括金属层,所述金属层设置在基板上,所述基板上设有保护层,所述保护层至少设置两层,所述保护层覆盖于所述金属层上,所述保护层对所述金属层和所述彩色光阻层进行分隔,当需要对所述彩色光阻层进行重工时,所述保护层能够更好的对所述金属层进行保护。
其中,所述保护层包括氧化硅层或氮化硅层,金属层上沉积至少两层氧化硅层或氮化硅层,从而更好的对金属层上进行覆盖,非常有效的防止金属毛刺裸露在保护层外,使得保护层能够更好的对金属层进行保护,氧化硅的化学性质比较稳定,不会与氢氧化钾溶液进行反应,有效的避免清洗剂对金属层的腐蚀破坏,能够非常好的对金属层进行保护;氮化硅层是一种超硬物质,且氮化硅材料耐磨损,高温时抗氧化,还能抵抗冷热冲击;而且通过进行多次化学气相沉积形成至少两层氧化硅层,中途不需要额外更换的原材料,也不需要额外更换设备,降低原材料成本、存储成本,物料清单不需要增加新的材料,方便流程管理和采购;同时化学气相沉积技术成熟,能够很好的控制氮化硅的使用量,进一步的减低了生产制造成本,使得显示面板具有更强的市场竞争力。
其中,所述保护层包括氮化硅层和氧化硅层;所述氮化硅层和氧化硅层堆叠设置,通过氮化硅层和氧化硅层堆叠设置,使得保护层能够更好的附着在金属层上,能够更好的对金属层上的金属毛刺进行覆盖,非常有效的防止金属毛刺裸露在保护层外,使得保护层能够更好的对金属层进行保护,能够非常有效的避免清洗剂对液晶面板的金属层的直接腐蚀,使得金属层能够保持完好,从而避免产生断线问题,进一步的提高了显示面板的耐用性。
其中,所述保护层包括至少两层氮化硅层和两层氧化硅层;所述氮化硅层和氧化硅层交替堆叠设置,使得保护层能够更好的附着在金属层上,能够更好的对金属层上的金属毛刺进行覆盖,非常有效的防止金属毛刺裸露在保护层外,使得保护层能够更好的对金属层进行保护。
其中,所述金属层包括第一金属层;所述第一金属上覆盖有所述保护层;所述彩色光阻层直接覆盖于所述保护层上。
其中,所述第一金属层包括源极金属层和漏极金属层,所述源极金属层与所述显示面板的源极驱动连接;所述漏极金属层与所述显示面板的像素电极连接;所述保护层覆盖于所述源极金属层和/或漏极金属层上。
其中,所述第一金属层采用铝或铝合金制成,铝或铝合金具有较好的导电性能和较低的电阻特性,能满足显示面板的需求,而且铝或铝合金的价格相对便宜,供货充足,方便采购,进一步的降低了显示面板的制造成本,使得显示面板具有更强的市场竞争力。
其中,所述金属层还包括第二金属层,所述第二金属层底部宽度大于顶部,所述第二金属层与显示面板的行扫描驱动连接,第二金属层底部宽度大于顶部,使得第二金属层的制作更加的方便,成型更加稳定,良品率更高,而且使得第二金属层底部的接触面积更大,粘粘效果更好,固定更加的牢固。
其中,所述第二金属层与所述第一金属层之间设有绝缘层,所述绝缘层材料为氧化硅或氮化硅,与后续步骤设置保护层的材料和方法相同,在后续设置保护层时,不需要额外更换的原材料,也不需要额外更换设备,降低原材料成本、存储成本,物料清单不需要增加新的材料,方便流程管理和采购。
根据本发明的另一个方面,本发明还公开了一种显示装置,所述显示装置包括背光模组和如上所述的显示面板。
与现有技术相比,本发明的技术效果是:
发明人研究发现,COT技术的显示面板,当发现制程出现问题时,会利用清洗剂对制程出现问题的区域进行重工剥除,但是在重工工艺中,清洗剂会对液晶面板的金属层进行腐蚀,进而产生断线问题,现有做法倾向不进行重工而是直接将玻璃报废,进而造成报废成本上升。本发明通过保护层的设置,将保护层覆盖于金属层上,采用COT技术对基板进行制程出现问题的区域重工时,保护层能够非常有效的避免清洗剂对液晶面板的金属层的直接腐蚀,使得金属层能够保持完好,从而避免产生断线问题,进而提升COT技术薄膜晶体管阵列基板的重工成功率而降低报废成本;而且金属层的侧边从微结构来看都有金属毛刺的现象,通过设置至少两层保护层,能够更好的对金属层上的金属毛刺进行覆盖,非常有效的防止金属毛刺裸露在保护层外,使得保护层能够更好的对金属层进行保护;同时采用保护层的设置能够很好的对制程出现问题的区域进行重工修复,而不需要将薄膜晶体管阵列基板进行报废处理,更加的绿色环保。

下面结合附图和较佳的实施例对本发明作进一步说明。
如图1所示是一种薄膜晶体管的结构,在COT技术于薄膜晶体管阵列基板工艺中,当发现金属层2上的制程出现问题时,会利用清洗剂对制程出现问题的区域进行重工剥除,清洗剂采用氢氧化钾溶液(KOH溶液)。
为此,申请人设计了一款未公开的显示面板,如图2所示,在重工工艺以后,发明人对薄膜晶体管的结构进行研究发现:金属层2的侧边从微结构来看都有金属毛刺213的现象,设置一层保护层3覆盖在金属层2上,保护层3能够对金属毛刺213进行很好的覆盖,但还是有极少部分的金属毛刺213贯穿保护层3伸出到保护层3的表面,导致金属毛刺213裸露保护层3上,对基板1进行重工时,清洗剂对腐蚀裸露在保护层3上的金属毛刺213,通过对贯穿保护层3的金属毛刺213的不断的腐蚀,使得保护层3形成腐蚀通道,清洗剂沿着腐蚀通道到达金属层2,对金属层2进行腐蚀,进而导致金属层2之间相互断裂,
发明人进一步研究发现,由于金属毛刺的存在,设置一层保护层3不能很好的粘附在金属层2上,而且清洗剂对金属层2进行腐蚀而导致断线问题。因此,发明人提成一种新的技术方案,可以进一步减少金属层断线问题,提升良品率。
下面参考图3至图6描述本发明实施例的显示面板结构示意图。
如图3所示,所述显示面板包括基板1和金属层2;所述金属层2设置在基板1上,所述基板1上设有保护层3,本发明通过保护层3的设置,将保护层3覆盖于金属层2上,采用COT技术对基板1上制程出现问题的区域进行重工时,保护层3能够非常有效的避免清洗剂对液晶面板的金属层2的直接腐蚀,使得金属层2能够保持完好,从而减少产生断线问题,进而提升COT技术薄膜晶体管阵列基板1的重工成功率而降低报废成本。所述保护层3设置两层,分别为第一保护层31和第二保护层32,第一保护层31覆盖设在基板1上,第二保护层32覆盖设在第一保护层上,由于金属层2的侧边从微结构来看都有金属毛刺213的现象,通过设置至少两层保护层3,能够更好的对金属层2上的金属毛刺213进行覆盖,如图3所示,第一保护层31能够非常有效的对金属毛刺213进行覆盖,第二保护层32能够非常有效的对裸露在第一保护层31上的金属毛刺213进行覆盖,非有效的防止金属毛刺213裸露在保护层3外,使得保护层3能够更好的对金属层2进行保护;同时采用保护层3的设置能够很好的对制程出现问题的区域进行重工修复,而不需要将薄膜晶体管阵列基板1进行报废处理,更加的绿色环保。
其中,所述保护层3为氧化硅层,即保护层3采用氧化硅材料制成,通过化学气相沉积(Chemical Vapor Deposition,CVD)技术将氧化硅沉积到金属层2上,在金属层2上进行一次化学气相沉积后,等待第一层氧化硅层冷却凝固形成第一保护层31,在第一保护层31进行第二次化学气相沉积后形成第二保护层32,重复以上步骤,使得金属层2上沉积至少两层氧化硅层,从而更好的对金属层2上进行覆盖,非常有效的防止金属毛刺213裸露在保护层3外,使得保护层3能够更好的对金属层2进行保护,氧化硅的化学性质比较稳定,不会与氢氧化钾溶液进行反应,有效的避免清洗剂对金属层2的腐蚀破坏,能够非常好的对金属层2进行保护;而且通过进行多次化学气相沉积形成至少两层氧化硅层,中途不需要额外更换的原材料,也不需要额外更换设备,降低原材料成本、存储成本,物料清单不需要增加新的材料,方便流程管理和采购,同时化学气相沉积技术成熟,能够很好的控制氧化硅的使用量,进一步的减低了生产制造成本,使得显示面板具有更强的市场竞争力。
当然也可以是,所述保护层3为氮化硅层,即保护层3采用氮化硅材料制成,通过化学气相沉积技术将氮化硅沉积到金属层2上,在金属层2上进行一次化学气相沉积后,等待第一层氮化硅层冷却凝固形成第一保护层31,在第一保护层31进行第二次化学气相沉积后形成第二保护层32,重复以上步骤,使得金属层2上沉积至少两层氮化硅层,从而更好的对金属层2上进行覆盖,非常有效的防止金属毛刺213裸露在保护层3外,使得保护层3能够更好的对金属层2进行保护,氮化硅不会与氢氧化钾溶液进行反应,有效的避免清洗剂对金属层2的腐蚀破坏,能够非常好的对金属层2进行保护,氮化硅是一种超硬物质,且氮化硅材料耐磨损,高温时抗氧化,还能抵抗冷热冲击,而且通过进行多次化学气相沉积形成至少两层氮化硅层,中途不需要额外更换的原材料,也不需要额外更换设备,降低原材料成本、存储成本,物料清单不需要增加新的材料,方便流程管理和采购,同时化学气相沉积技术成熟,能够很好的控制氮化硅的使用量,进一步的减低了生产制造成本,使得显示面板具有更强的市场竞争力。
如图4所示,图示中的最外层采用阴影的画法,只是区分保护层3采用氮化硅层和氧化硅层堆叠,且不特指是氮化硅层或氧化硅,作为本发明的又一个实施例,所述保护层3包括氮化硅层和氧化硅层,通过化学气相沉积技术将氧化硅沉积到金属层2上,等待氧化硅层冷却凝固形成第一保护层31,然后化学气相沉积技术将氮化硅沉积到氧化硅层上形成第二保护层32,当然也可以是先设置氮化硅层作为第一保护层31,再将氧化硅层覆盖在氮化硅层上形成第二保护层32,通过氮化硅层和氧化硅层堆叠设置,使得保护层3能够更好的附着在金属层2上,能够更好的对金属层2上的金属毛刺213进行覆盖,非常有效的防止金属毛刺213裸露在保护层3外,使得保护层3能够更好的对金属层2进行保护,能够非常有效的避免清洗剂对液晶面板的金属层2的直接腐蚀,使得金属层2能够保持完好,从而避免产生断线问题,进一步的提高了显示面板的耐用性。
如图5所示,图示中未示意出金属毛刺213,金属毛刺213的示意可参照图3或图4,作为本发明的另外一个实施例,所述保护层3包括至少两层氮化硅层和两层氧化硅层;通过化学气相沉积技术将氧化硅沉积到金属层2上,等待氧化硅层冷却凝固,然后化学气相沉积技术将氮化硅沉积到氧化硅层上,再在氮化硅层上设置第二层氧化硅层,最后在第二层氧化硅层上设置第二层氮化硅层,当然也可以是先设置氮化硅层,再将氧化硅层覆盖在氮化硅层上,使得氮化硅层和氧化硅层交替堆叠设置,使得保护层3能够更好的附着在金属层2上,能够更好的对金属层2上的金属毛刺213进行覆盖,非常有效的防止金属毛刺213裸露在保护层3外,使得保护层3能够更好的对金属层2进行保护。
金属层2包括第一金属层21;第一金属上覆盖有保护层3;彩色光阻层直接覆盖于保护层3上,通过保护层3将彩色光阻层与第一金属层21进行分隔开,当发现彩色光阻层其中一层或多层的制程出现问题时,会利用清洗剂对彩色光阻层进行重工剥除,保护层3能够非常好的对第一金属层21进行保护,保护层3能够非常有效的避免清洗剂对液晶面板的金属层2的直接腐蚀,使得金属层2能够保持完好,从而避免产生断线问题;同时采用保护层3的设置能够很好的对彩色光阻层进行重工修复,而不需要将薄膜晶体管阵列基板1进行报废处理,更加的绿色环保。
第一金属层21包括源极金属层211和漏极金属层212,源极金属层211与显示面板的源极驱动连接;漏极金属层212与显示面板的像素电极连接;保护层3覆盖于源极金属层211和/或漏极金属层212上。
第一金属层21采用铝或铝合金制成,铝或铝合金具有较好的导电性能和较低的电阻特性,能满足显示面板的需求,而且铝或铝合金的价格相对便宜,供货充足,方便采购,进一步的降低了显示面板的制造成本,使得显示面板具有更强的市场竞争力。
其中,金属层2还包括第二金属层22,第二金属层22底部宽度大于顶部,第二金属层22与显示面板的行扫描驱动连接,第二金属层22底部宽度大于顶部,使得第二金属层22的制作更加的方便,成型更加稳定,良品率更高,而且使得第二金属层22底部的接触面积更大,粘粘效果更好,固定更加的牢固,其中第二金属层22的截面优选为梯形,特别是等腰梯形。
如图6所示,显示面板与行扫描驱动连接的第二金属层22采用三层结构,从下往上依次为与基板1连接的第一高附着金属层221、中间导电层222和第二高附着金属层223。中间导电层222可以采用较低电阻特性的金属,有效地降低显示面板第二金属层22的电阻与寄生电容,第二金属层22的第一高附着金属层221和第二高附着金属层223则采用附着性能较好的金属,这样中间导电层222可以很好的与第一高附着金属层221和第二高附着金属层223粘粘固定,同时中间导电层222还可以通过第一高附着金属层221和第二高附着金属层223与上下层粘粘固定,粘粘性更好,不容易导致中间导电层222与上下层剥离,即能很好的满足显示面板第二金属层22的电性性能,又能很好的与上下层粘粘固定,提升产品良率,降低生产成本。
其中,中间导电层222的厚度大于第一高附着金属层221和第二高附着金属层223的厚度。中间导电层222的厚度大于第一高附着金属层221的厚度,也大于第二高附着金属层223的厚度,中间导电层222可以采用较低电阻特性的金属,厚度更大能有效地降低面板第二金属层22的电阻与寄生电容,第一高附着金属层221和第二高附着金属层223则采用附着性能较好的金属,中间导电层222通过第一高附着金属层221和第二高附着金属层223与上下层连接,粘粘性更好,不容易导致中间导电层222与上下层剥离,第一高附着金属层221和第二高附着金属层223主要是用来与上下层粘粘厚度小可以节约成本,可选的,中间导电层222的厚度可以大于第一高附着金属层221加第二高附着金属层223的厚度。
可选的,其中,中间导电层222底部宽度大于顶部,第一高附着金属层221宽度与中间导电层222底部宽度相同,第二高附着金属层223宽度与中间导电层222顶部宽度相同。中间导电层222底部宽度大于顶部,方便制作,成型稳定,良品率高,第一高附着金属层221宽度与中间导电层222底部宽度相同,第二高附着金属层223宽度与中间导电层222顶部宽度相同,制作方便,中间导电层222与第一高附着金属层221和第二高附着金属层223接触面积最大,粘粘效果更好,其中中间导电层222的截面优选为梯形,特别是等腰梯形。
