Description

一种显示装置及其制作方法
技术领域
本发明涉及显示器技术领域,更具体地说,涉及一种一种显示装置及其制作方法。
背景技术
目前常用液晶显示器有TN(Twist Nematic;扭转向列型)模式,VA(VerticalAlignment;垂直对齐)模式,IPS(In-plane switching;平面方向转换)模式和FFS(FringeField Switching,边缘场开关)模式等。现有VA显示模式中最常用为PSVA(Polymerstabilized vertical alignment,聚合物稳定垂直排列)技术,因其具有高对比度和响应速度快的优势。PSVA液晶显示已经成为了目前最广泛的显示技术,但人们对显示技术的要求也越来越高,广视角、高穿透率一直是未来发展的重要方向。然而PSVA显示模式视角相对较差,即侧视角和正视角亮度和颜色差异明显,而且PSVA的穿透率(transmission,Tr)与Δn(光学双折射值)关系如公式1所示,随着波长增大,Δn逐渐减小,导致在短波长区域Tr容易出现反转,即电压增大时长波长区域Tr增加而短波长区域Tr降低,导致颜色偏黄(Blue亮度低,Red、Green亮度高,色点偏黄)。
Figure BDA0002309955160000011
现有技术提高穿透率的最有效方式之一是提高上述公式中的Δnd,增加d即加大面板盒厚度,会使液晶用量增加成本上升;常用方式是维持d不变,增加Δn。但增大Δn更容易使短波长Tr发生反转,出现颜色偏黄问题。而且色点越黄,视角越差(需要光学调节维持白点平衡,导致正视和侧视亮度差异更大)。而通过在液晶中加入手性剂,可使液晶沿着多方向倾倒,同时增加Δn,使液晶显示模式成为反转TN模式,可有效的提高穿透率,同时提高兰像素的穿透率,改善白点偏黄的问题,而且液晶分子可以沿着不同方向倾倒,使不同方位角具有相同亮度,从而实现高穿透率大视角显示。然而,在设计时,因为手性剂的存在,使液晶发生旋转,导致局部区域液晶分子无法沿着穿透率最大方向倾倒,从而产生暗纹,影响显示装置穿透率。

附图说明
下面将结合附图及实施例对本发明作进一步说明,附图中:
图1为螺距的结构示意图;
图2为液晶单元间隙的结构示意图;
图3为本发明实施例提供的黑色矩阵的非对称设置示意图;
图4为本发明实施例提供的驱动电极的非对称设置示意图;
图5为本发明实施例提供的驱动电极非对称设置结合黑色矩阵对称设置的示意图;
图6为本发明实施例提供的一种显示装置的制作方法的流程图。
具体实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解,现对照附图详细说明本发明的具体实施方式。
本发明提供一种显示装置,包括第一基板及第二基板,还包括设置于所述第一基板与所述第二基板之间的液晶;所述液晶包括手性剂,所述第一基板上设置有驱动电极,所述第二基板上设置有黑色矩阵;优选的,所述第一基板为薄膜晶体管阵列基板,所述第二基板为彩膜基板,所述液晶为负性液晶。在本发明所述的显示装置中,第一基板和第二基板可以为柔性基板或者普通基板。在两个基板中间加入液晶,Δnd介于300nm至500nm之间,其中Δn为光学双折射值,d为面板盒厚度,同时在液晶中增加手性剂,维持螺距为液晶单元间隙值的2倍到7倍,提升穿透率同时改善色点偏黄或偏绿问题,降低色偏,改善视角问题。
参见图1及图2,图1为螺距的结构示意图,图2为液晶单元间隙的结构示意图。图1中,手性液晶呈液晶层状排列,层内液晶取向有序,层与层之间液晶有一定角度旋转,其中图1中左侧n表示旋转方向,当不同层的指向矢沿螺旋方向旋转360°后,又回到初始方向的层间距为螺距,因此图中P即为螺距。图2中,液晶单元间隙为gap,gap为上基板与下基板之间的距离。因此螺距为液晶单元间隙值的2倍到7倍即为2≤P/gap≤7。
其中,所述驱动电极为非对称设置或所述黑色矩阵为非对称设置。参见图3,图3为本发明实施例提供的黑色矩阵的非对称设置示意图,黑色矩阵的非对称设置具体为:在暗纹宽区域增加黑色矩阵的宽度,在暗纹窄区域缩小黑色矩阵的宽度。
参见图4,图4为本发明实施例提供的驱动电极的非对称设置示意图,驱动电极的非对称设置为:根据像素周边暗纹对所述驱动电极进行非对称设置。
参见图5,图5为本发明实施例提供的驱动电极非对称设置结合黑色矩阵对称设置的示意图,该实施例为图4所示实施例的进一步细化。
此外,还可以采用非对称ITO样式设计,在暗纹明显区域ITO设计外延,增加边缘电场强度,诱导周边液晶配向,使暗纹外移,达到提升透过率的效果。其中,ITO导电玻璃是在钠钙基或硅硼基基片玻璃的基础上,利用溅射、蒸发等多种方法镀上一层氧化铟锡(俗称ITO)膜加工制作成的。液晶显示器专用ITO导电玻璃,还会在镀ITO层之前,镀上一层二氧化硅阻挡层,以阻止基片玻璃上的钠离子向盒内液晶里扩散。
参见图6,图6为本发明实施例提供的一种显示装置的制作方法的流程图,该显示装置的制作方法包括步骤S1-S2:
S1、在液晶中掺杂手性剂,并将掺杂有所述手性剂的液晶设置于第一基板与第二基板之间;其中,第二基板可视情况增加红绿蓝彩色滤光层、黑色矩阵等,以实现彩色显示、防止漏光等有益效果。步骤S1包括步骤S11-S13:
S11、将液晶注入液晶层,其中,所述液晶的光学双折射值与面板盒厚度的乘积的范围为300nm至500nm;例如:在基板上制作配向层,然后将液晶注入液晶层,所述液晶为负性液晶,液晶Δnd介于300nm至500nm之间。通常制作显示器时,上下电极表层还镀上一层很薄的高分子塑胶(如:polyimide),称之液晶分子配向层。
S12、在液晶中增加手性剂,螺距为液晶单元间隙值的2倍到7倍;由于液晶中增加手性剂,导致pixel周边电场较弱区域液晶发现旋转,导致不同区域旋转角度不同,造成暗纹宽度差异。而且,添加手性剂的液晶,现有技术已有实验证实在不同电压状态下增加手性剂可以有效增加短波长区域,即波长500nm以下区域可以增大透过率,从而增加蓝色光的亮度,即改善白点偏绿、偏黄的问题。
S13、进行贴合形成液晶盒,对液晶进行预设的制程处理。进行贴合形成液晶盒,对液晶和进行PSVA(Polymer stabilized vertical alignment,聚合物稳定垂直排列技术)制程处理,即加电进行UV照射(紫外线照射),形成预倾角,形成所示液晶显示装置。
S2、将驱动电极非对称设置或将黑色矩阵非对称设置。步骤S2包括步骤S21-S22:
S21、根据像素周边暗纹对所述驱动电极进行非对称设置。参见图2,可以看出驱动电极依据暗纹区域进行调整,最终所组成的暗纹区域面积不规则亦不对称。
S22、在暗纹宽区域增加黑色矩阵的宽度,在暗纹窄区域缩小黑色矩阵的宽度。本方案利用黑色矩阵非对称性设计,暗纹宽区域加宽黑色矩阵,窄区域缩小黑色矩阵的宽度,可有效利用黑色矩阵非对称设计缩小像素间距,达到提升透过率的效果。
通过上述方案,在液晶中加入手性剂,同时增加Δn(即光学双折射值),使液晶显示模式成为反转TN(Twist Nematic;扭转向列型)模式,可有效的提高穿透率,同时提高蓝像素的穿透率,改善白点偏黄的问题;采用非对称电极或者黑色矩阵设计,改善周边暗纹,提升穿透率。
上面结合附图对本发明的实施例进行了描述,但是本发明并不局限于上述的具体实施方式,上述的具体实施方式仅仅是示意性的,而不是限制性的,本领域的普通技术人员在本发明的启示下,在不脱离本发明宗旨和权利要求所保护的范围情况下,还可做出很多形式,这些均属于本发明的保护之内。
