本公开涉及显示技术领域,尤其涉及一种显示面板、显示面板的制作方法和显示装置。
这里的陈述仅提供与本公开有关的背景信息,而不必然地构成现有技术。
随着科技的发展和进步,液晶显示器由于具备机身薄、省电和辐射低等热点而成为显示器的主流产品,得到了广泛应用。现有市场上的液晶显示器大部分为背光型液晶显示器,其包括液晶面板及背光模组(Backlight Module)。液晶面板的工作原理是在两片平行的玻璃基板当中放置液晶分子,并在两片玻璃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,薄膜晶体管液晶显示器(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,薄膜晶体管液晶显示器包含液晶面板和背光模组,液晶面板包括彩 膜基板(Color Filter Substrate,CF Substrate,也称彩色滤光片基板)、薄膜晶体管阵列基板(Thin Film Transistor Substrate,TFT-Substrate)和光罩(Mask),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)。显示面板时常有画面闪烁的情况发生,降低了显示面板的画面品质,影响使用效果和观看体验,本领域的技术人员一直在探索这个问题的解决方法,如此一来,一个可以解决此问题的方法就显得相当的重要。
本公开的目的是提供一种显示面板、显示面板的制作方法和显示装置。
为实现上述目的,本公开提供了一种显示面板,包括:
第一基板;
第二基板,所述第一基板与所述第二基板相对设置;
色阻层,形成于所述第一基板上;
共电极,形成于所述色阻层上;以及
数据线,形成于所述第二基板上;
所述第一基板上的共电极上设有第一凹槽,所述第一凹槽向第一基板方向凹陷,所述第一凹槽与所述第二基板上的数据线位置相对应。
本公开还提供了一种显示面板的制作方法,包括步骤:
在第一基板上形成色阻层;
其中,形成色阻层的步骤包括:在色阻层上形成凹槽;
在所述色阻层上形成共电极;
使得共电极在对应所述色阻层的凹槽的位置处形成第一凹槽,使得所述第一凹槽向第一基板的方向凹陷,且与所述第二基板上的数据线的位置相对应。
本公开还提供了一种显示装置,包括上述显示面板。
相对于数据线与共电极间距离较近的方案来说,本申请中,共电极上设有向第一基板方向凹陷的第一凹槽,增加了数据线与共电极间的距离,减小了色阻层的厚度,进而减少数据线与共电极之间的寄生电容;当在对像素进行充电和放电的过程中,可以有效的避免数据线电压变化时导致的共电极信号不稳定的情况发生,有效避免画面闪烁,进而有效提高显示面板的画面品质。

这里所使用的术语仅仅是为了描述具体实施例而不意图限制示例性实施例。除非上下文明确地另有所指,否则这里所使用的单数形式“一个”、“一项”还意图包括复数。还应当理解的是,这里所使用的术语“包括”和/或“包含”规定所陈述的特征、整数、步骤、操作、单元和/或组件的存在,而不排除存在或添加一个或更多其他特征、整数、步骤、操作、单元、组件和/或其组合。
下面结合附图和实施例对本公开作进一步说明。
双栅极驱动是发明人知晓的一种像素驱动设计,其在阵列基板栅极驱动(GOA)的结构上有明显的成本优势。双栅极驱动即扫描线(gate)数量增加一倍,而数据线(data)数量减少一倍。如图1为双栅极驱动的基本架构。图2为其像素的阵列(array)侧与彩色滤光片(Color Filter,CF)侧结构,阵列(array)侧主要包括扫描线(gate)与数据线(data)以及提供共电极的共用电极线(a-com);彩色滤光片(Color Filter,CF)侧主要包括用来提供彩色的R/G/B色阻,用来遮 挡非色阻区防止漏光并且避免不同颜色色阻混合的遮光材料(BM),以及覆盖整面作为共电极(cf-com)的透明导电薄膜(Indium Tin Oxide,ITO)。图2中a的宽度小于b的宽度,b对应的下基板相应位置第一金属线组处的金属线路较复杂。遮光材料(BM)宽度应可以全部覆盖住该金属线路,保证不漏光。其中在有线路的地方由遮光材料(BM)覆盖。遮光材料(BM)在两个子像素间的距离不相同,其中a(a=14±2um)为单共用电极线上方遮光材料(BM)宽度,b(b=21±2um)为数据线(data)上方的遮光材料(BM)的宽度,首先a处为色阻边缘也接近阵列(array)侧金属边缘,a处遮光材料(BM)在共用电极线的正上方,设置该宽度a接近单共用电极线的宽度,比此处共用电极线稍宽,尽量保证小开口率的同时,保证此处不漏光;其次a处也是两色阻相邻位置,由于色阻制程精度限制,此处会有色阻重叠,会影响画面显示效果,遮光材料(BM)可遮挡该处混色对画面品质的影响。故此发明中定义宽度为a的遮光材料(BM)侧为窄框区,遮光材料(BM)宽度为b处为宽框区。在子像素两侧a、b交替出现;其厚度在各处相同,都为1±0.3um。
如图4至图8所示,在一实施例中,公布了一种显示面板100包括:
第一基板110;
第二基板120,所述第一基板110与所述第二基板120相对设置;
色阻层130,形成于所述第一基板110上;
共电极140,形成于所述色阻层130上;以及
数据线150,形成于所述第二基板120上;
所述第一基板110上的共电极140上设有第一凹槽141,所述第一凹槽141向第一基板110方向凹陷,所述第一凹槽141与所述第二基板120上的数据线150位置相对应。
相对于数据线150与共电极140间距离较近的方案来说,本申请中,共电极140上设有向第一基板110方向凹陷的第一凹槽141,增加了数据线150与共电极140间的距离,减小了色阻层130的厚度,进而减少数据线150与共电极140之间的寄生电容;当在对像素进行充电和放电的过程中,可以有效的避免数据线150电压变化时导致的共电极140信号不稳定的情况发生,有效避免画面闪烁,进而有效提高显示面板100的画面品质。图4为子像素两侧的色阻层130的设计,左侧为第一基板110上没有数据线150对应的色阻层130的设计,右侧为第一基板110上有数据线150对应的色阻层130的设计。
如图5所示,在一实施例中,所述色阻层130包括黑色色阻层131,所述黑色色阻层131上设置有凹槽,所述第一凹槽141形成于所述黑色色阻层131的凹槽上。这是一种形成第一凹槽141的方法。
如图6所示,在一实施例中,所述色阻层130包括彩色色阻层132,所述彩色色阻层132上设置有凹槽,所述第一凹槽141形成于所述彩色色阻层132的凹槽上。这是另一种形成第一凹槽141的方法。
如图7至图8所示,在一实施例中,所述色阻层130包括黑 色色阻层131和彩色色阻层132,所述黑色色阻层131和彩色色阻层132上设置有凹槽,所述彩色色阻层132形成于所述黑色色阻层131上,所述第一凹槽141形成于所述彩色色阻层132的凹槽上。这是另一种形成第一凹槽141的方法,可以更加灵活的来形成凹槽.
本方案中,彩色色阻层132的凹槽可以是在对应两个不同色阻的交接处形成。
在一实施例中,所述第一凹槽141的宽度大于所述数据线150的宽度。
本方案中,数据线150和共用电极线160位于不同金属层,数据线150和共用电极线160之间存在绝缘层170;则数据线150和共用电极线160的高度不一样,第一凹槽141的宽度大于数据线150的宽度,则数据线150与第一凹槽141之间的距离增加,进而数据线150与共电极140之间的距离增加,降低了数据线150与共电极140之间的寄生电容;当在对像素进行充电和放电的过程中,可以有效的避免数据线150电压变化时导致的共电极140信不号稳定的情况发生,有效的避免画面闪烁,进而有效提高显示面板100的画质品质。
在一实施例中,所述显示面板100包括共用电极线160,所述共用电极线160位于所述数据线150的两侧;所述数据线150与其两侧的所述共用电极线160形成第一金属线组180;所述第一凹槽141的宽度小于所述第一金属线组180的宽度。

在一实施例中,对应凹槽的位置处的所述黑色色阻层131的膜厚为X,其中,0.4微米≤X≤0.8微米。
相对于对应凹槽的位置处的黑色色阻层131的膜厚大于等于0.7微米(μm),且小于等于1.3微米(μm)的方案来说;本方案中,对应凹槽的位置处的黑色色阻层131的膜厚为X,其中,0.4微米≤X≤0.8微米;若黑色色阻层131的膜厚小于0.4微米,则凹槽处易损坏,发生漏光的现象;若黑色色阻层131的膜厚大于0.8微米,则凹槽处的共电极140与数据线150之间依然存在寄生电容,当数据线150的电压变化时,易造成共电极140信号的变化;本方案既保证了凹槽的坚固性,又可以最大限度的较少数据线150与共电极140间的寄生电容,从而有效的避免数据线150中电压变化对共电极140信号的影响,进而避免显示面板100的画面闪烁的情况发生,提升显示面板100的画面品质。
