技术领域
本发明涉及显示器设计领域,特别涉及一种阵列基板及其制备方法、显示面板、显示装置。
背景技术
在阵列基板周边走线的设计中,周边走线中输出区域内的栅极周边走线与数据线周边走线之间需要交替布线以解决空间不足问题,但是由于数据线周边走线背离衬底基板一侧的保护层的厚度(200~400nm)小于栅极周边走线背离衬底基板一侧保护层(绝缘层+保护层)的厚度(600nm~800nm),因此数据线周边走线更易遭受外界异物的划伤或压伤,进而导致线不良问题。
发明内容
本发明提供了一种阵列基板及其制备方法、显示面板、显示装置,其中,该阵列基板能够减少数据线周边走线被外界异物压伤或划伤的概率,提高产品使用稳定性。

上述阵列基板中,由于保护层与栅极周边走线图形正对的部位背离衬底基板的表面高于保护层与所述数据线周边走线正对部位背离所述衬底基板的表面,因此,当外界异物在与阵列基板的周边走线区域接触时首先与保护层与栅极周边走线正对的部位接触,从而减少数据线周边走线被外界异物压伤或划伤的概率,提高产品使用稳定性。

具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
如图1-图3所示,本发明实施例提供了一种阵列基板、显示面板及显示装置,该阵列基板包括衬底基板1、形成于衬底基板1上的栅极周边走线2、栅绝缘层3、数据线周边走线5、保护层6,其中,保护层6与栅极周边走线2图形正对部位背离衬底基板1的表面高于保护层6与数据线周边走线5正对部位背离衬底基板的表面。由于保护层6与栅极周边走线2图形正对部位背离衬底基板1的表面高于保护层6与数据线周边走线5正对部位背离衬底基板1的表面,所以,在外界异物与阵列基板的周边周线区域接触时,外界异物首先与保护层6与栅极周边走线2正对的部位接触,减少了外界异物与保护层6与数据线周边走线5部位接触的几率,进而能够减小数据线周边走线5被外界异物压伤或划伤的概率,提高了阵列基板的产品性能稳定性。且提高了包括上述阵列基板的显示面板、以及包括上述显示面板的显示装置的产品性能稳定性。
本发明实施例还提供了一种上述阵列基板的制备方法,该制备方法包括:在衬底基板上依次形成栅极周边走线图形、栅绝缘层图形、数据线周边走线图形、保护层的图形,其中,所述保护层与所述栅极周边走线图形正对部位背离所述衬底基板的表面高于所述保护层与所述数据线周边走线正对部位背离所述衬底基板的表面。
具体地,上述阵列基板可以通过下述具体结构实现保护层与栅极周边走线图形正对部位背离衬底基板的表面高于保护层与数据线周边走线正对部位背离衬底基板的表面:
方式一:如图1所示,本发明实施例提供的阵列基板包括衬底基板1、形成于衬底基板1上的栅极周边走线2、栅绝缘层3、数据线周边走线5、保护层6。其中,栅绝缘层3与数据线周边走线5相对的部位设有凹槽,且数据线周边走线5的至少一部分位于凹槽内。
上述阵列基板中,因数据线周边走线5的至少一部分位于凹槽内,在不减少数据线周边走线5的厚度的同时可以减小其背离衬底基板1的表面与衬底基板1之间的距离,使得保护层6与数据线周边走线5正对的部位更加靠近衬底基板1,从而使保护层6与栅极周边走线2图形正对部位背离衬底基板1的表面高于保护层6与数据线周边走线5正对部位背离衬底基板1的表面。
优选地,该凹槽沿垂直于衬底基板1并指向衬底基板1的方向的深度为100~400nm,如100nm、150nm、200nm、250nm、300nm、350nm、400nm。
相应地,上述方式一中提供的阵列基板的可以通过下述制备方法制备,该制备方法具体包括:
在衬底基板1通过一次构图工艺上形成栅金属层,并形成栅极周边走线2的图形;
通过HTM构图工艺在栅极周边走线2的图形上形成栅绝缘层3的图形,并形成栅绝缘层3的图形中包括在数据线周边走线5的设计区域内的凹槽;
通过一次构图工艺在栅绝缘层3的图形上形成源漏金属层,并形成数据线周边走线5的图形,数据线周边走线5的至少一部分位于凹槽内;
在数据线周边走线5的图形上形成保护层6。
方式二:如图2所示,本发明实施例提供的阵列基板包括衬底基板1、形成于衬底基板1上的栅极周边走线2、栅绝缘层3、半导体层4、数据线周边走线5、保护层6。其中,半导体层4位于栅绝缘层3与保护层6之间、且沿垂直于衬底基板1方向与栅极周边走线2重叠。
因位于栅绝缘层3与保护层6之间的半导体层4沿垂直于衬底基板1的方向与栅极周边走线2重叠,使得半导体层4与栅极周边走线2正对的部位远离衬底基板,进而能够使半导体层4背离衬底基板1的表面的高度高于数据线周边走线5的表面背离衬底基板1的表面的高度,从而使保护层6与栅极周边走线2图形正对部位背离衬底基板1的表面高于保护层6与数据线周边走线5正对部位背离衬底基板1的表面。
优选地,沿垂直于衬底基板并背离衬底基板的方向,半导体层的厚度为100~300nm,如100nm、130nm、150nm、200nm、230nm,250nm、300nm。
相应地,上述方式二中提供的阵列基板可以通过下述制备方法制备,该制备方法包括:
在衬底基板1上通过一次构图工艺形成栅金属层,并形成栅极周边走线2的图形与栅绝缘层3的图形;
在栅绝缘层3上形成半导体层4的图形,其中,半导体层4的图形中保留沿垂直于衬底基板方向与栅极周边走线2重叠的部位;
在栅绝缘层3的图形上形成源漏金属层,并形成数据线周边走线5;
在数据线周边走线图形上形成保护层6。
方式三:如图3所示,本发明实施例提供的阵列基板包括衬底基板1、形成于衬底基板1上的栅极周边走线2、栅绝缘层3、半导体层4、数据线周边走线5、保护层6。其中,栅绝缘层3与数据线周边走线5相对的部位设有凹槽,且数据线周边走线5的一部分位于凹槽内;半导体层位于栅绝缘层3与保护层6之间、且沿垂直于衬底基板1方向与栅极周边走线2重叠。
上述阵列基板中,因数据线周边走线5的至少一部分位于凹槽内,在不减少数据线周边走线5的厚度的同时可以减小其背离衬底基板1的表面与衬底基板1之间的距离,使得保护层6与数据线周边走线5正对的部位更加靠近衬底基板1;同时位于栅绝缘层3与保护层6之间的半导体层4沿垂直于衬底基板1的方向与栅极周边走线2重叠,使得半导体层4与栅极周边走线2正对的部位远离衬底基板,进而能够使半导体层4背离衬底基板1的表面高于数据线周边走线5的表面背离衬底基板1的表面。因此保护层6与栅极周边走线2图形正对部位背离衬底基板1的表面高于保护层6与数据线周边走线5正对部位背离衬底基板1的表面。
优选地,该凹槽沿垂直于衬底基板1并指向衬底基板1的方向的深度为100~400nm,如100nm、150nm、200nm、250nm、300nm、350nm、400nm。
优选地,沿垂直于衬底基板1并背离衬底基板1的方向,该半导体层4的厚度为100~300nm,如100nm、130nm、150nm、200nm、230nm,250nm、300nm。
相应地,上述方式三中提供的阵列基板的制备方法具体实施方式为:
在衬底基板1通过一次构图工艺上形成栅金属层,并形成栅极周边走线2的图形;
在栅极周边走线2的图形上形成栅绝缘层3,栅绝缘层3的图形中包括在数据线周边走线5的设计区域形成的凹槽;
在栅绝缘层3的图形上形成半导体层4,其中,半导体层4的图形中沿垂直于衬底基板1方向与栅极周边走线2重叠;
在栅绝缘层3的图形上通过一次构图工艺形成源漏金属层,并形成数据线周边走线5的图形,其中,数据线周边走线5的至少一部分位于上述凹槽内;
在数据线周边走线5的图形上形成保护层6。
当然,上述阵列基板还可以通过其他结构实现,。
显然,本领域的技术人员可以对本发明实施例进行各种改动和变型而不脱离本发明的精神和范围。这样,倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内,则本发明也意图包含这些改动和变型在内。
