Description

曲面液晶面板的制作方法
技术领域
本发明涉及显示技术领域,尤其涉及一种曲面液晶面板的制作方法。
背景技术
液晶显示器(Liquid Crystal Display,LCD)包括壳体、设于壳体内的液晶面板及设于壳体内的背光模组,其中液晶面板由一彩色滤光片基板(Color Filter,CF)、一薄膜晶体管阵列基板(Thin Film Transistor Array Substrate,TFT Array Substrate)以及一填充于两基板间的液晶层(Liquid Crystal Layer)所构成。CF基板和Array基板的相对内侧设有透明电极。液晶显示器通过电场对液晶分子的取向进行控制,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。随着显示技术的发展,人们对消费性电子产品的要求已经不单单局限于功能性,同时也更转向于设计性、艺术性以及具有良好的视觉体验性方面,如此前应运而生的曲面液晶显示器,不仅设计新颖,同时视觉体验效果更佳。
曲面液晶面板是曲面液晶显示器的核心组成部分。当前曲面液晶面板的制作方法为:先将制作完成的CF基板与Array基板在平面状态下贴合,形成一平板状的液晶面板,再将该平板状的液晶面板在外力作用下,使原本呈平板状态的液晶面板发生弯曲,并依照液晶面板的设计尺寸以及观赏距离来决定弯曲的程度(曲率半径)。
当前主流的LCD液晶面板,在CF基板侧设置有黑色矩阵(Black Matrix,BM),以阻止每个像素处漏光的发生,同时在CF基板与Array基板间会设置光阻间隔物(PhotoSpacer,PS),以维系两个基板间的间距,避免显示出现异常。
如图1所示,按照当前曲面液晶面板的制作方法,当液晶面板发生弯曲时,由于CF基板100与Array基板200的相对移动,会造成在弯曲部位的黑色矩阵110相对TFT像素电极移动,引起开口率的变化,造成在显示过程中出现视觉上的暗团。而当液晶面板进一步弯曲,CF基板100与Array基板200的相对偏移量进一步增大时,两个相邻的色阻甚至有可能移动到数据线210(Data Line)附近,而由于数据线210附近的电场会引起液晶发生偏转,造成漏光发生,这种显示缺陷在显示纯色画面时尤为明显。从而CF基板100与Array基板200的相对偏移会导致色阻移动,造成混色色偏和显示颜色不均。
如图2所示,由于液晶面板的弯曲,还会使得原本在平板状态时布置分配合理的光阻间隔物400随着从液晶面板中央至左右两边弯曲程度的不同,而发生不同程度的按比例的顶压现象。随着液晶面板的弯曲,图2中所标注的B、C、D及B’、C’、D’位置处的弧度发生变化,使得不同位置的光阻间隔物400对Array基板200的顶压效果不同,从而导致不同位置的光阻间隔物400的高度不同,很容易引发由于不同位置的光阻间隔物400的高度不同而造成的液晶层300盒厚不均匀的风险。
总之,对于四周已被框胶600粘结的液晶面板,从平板状态到弯曲状态时,势必会由于Array基板200与CF基板100的相对移动而造成开口率、以及整个液晶面板不同位置的液晶层300盒厚发生变化,进而带来相关的显示缺陷。
发明内容
本发明的目的在于提供一种曲面液晶面板的制作方法,能够避免现有曲面液晶面板制作方法造成的显示缺陷,有效提高产品良率,且制程简便、不增加额外成本。
为实现上述目的,本发明提供一种曲面液晶面板的制作方法,包括如下步骤:
步骤1、预设曲面液晶面板的CF基板与Array基板的曲率半径;
步骤2、制作CF基板与Array基板,所述CF基板与Array基板均呈平面状态;
所述Array基板上制作有数条等间距排列的数据线,所述CF基板上制作有呈阵列式排布的黑色矩阵,根据步骤1中预设的曲率半径将每相邻两条数据线之间的间距L2与黑色矩阵在数据线排列方向上的间隔L1设置为不等;
步骤3、分别对所述CF基板、Array基板进行弯曲,以达到步骤1中预设的曲率半径;
步骤4、将弯曲后的CF基板与Array基板以曲面贴合方式进行真空贴合,形成曲面液晶面板。
所述曲面液晶面板的制作方法,还包括步骤5、对真空贴合后的CF基板与Array基板进行切割。
其中,所述CF基板与Array基板上具有相互对应的显示区域,所述步骤2包括在所述CF基板或Array基板上围绕显示区域涂覆一圈框胶,并将液晶滴入所述框胶内形成液晶层。
其中,制作所述黑色矩阵采用光罩进行曝光。
其中,在步骤2所述CF基板与Array基板在平面状态时,每相邻两条数据线之间的间距L2与黑色矩阵在数据线排列方向上的间隔L1成比例关系;设所述CF基板的预设曲率半径为R,CF基板与Array基板之间的液晶层的盒厚为d,则L1:L2=R:(R+d)或L1:L2=R:(R-d)。
其中,在步骤4所述CF基板与Array基板以曲面贴合方式进行真空贴合时,黑色矩阵沿曲面液晶面板弯曲方向与每一数据线在曲面液晶面板的径向上重合,使得Array基板与CF基板的像素区域相匹配。
其中,在所述步骤2中,所述CF基板上还制作有多个光阻间隔物,根据步骤1中预设的CF基板的曲率半径将位于CF基板不同位置处的光阻间隔物的高度设置为不等。

其中,所述步骤2采用平板涂布方式制作CF基板与Array基板。
其中,所述步骤5采用竖版切割方式进行切割。
本发明的有益效果:本发明提供的一种曲面液晶面板的制作方法,使CF基板与Array基板分别弯曲后,再在曲面状态下贴合、切割,并对黑色矩阵、光阻间隔物进行合理设计。该方法不同于现有曲面液晶面板的制作方法中对整个平板液晶面板进行弯曲,解决了平板液晶面板弯曲过程中由于CF基板与Array基板的相对移动所导致的黑色矩阵位移、光阻间隔物高度不同的问题,避免了现有曲面液晶面板制作方法造成的显示缺陷,有效提高产品良率,且制程简便、不增加额外成本。

具体实施方式
为更进一步阐述本发明所采取的技术手段极其效果,以下结合本发明的优选实施例极其附图进行详细描述。
请参阅图3,本发明提供一种曲面液晶面板的制作方法,包括如下步骤:
步骤1、根据设计要求预设曲面液晶面板的CF基板与Array基板的曲率半径。
需要说明的是,CF基板的预设曲率半径与Array基板的预设曲率半径之间相差一个液晶层盒厚,将面向观看者的CF基板的预设曲率半径设定为曲面液晶面板的曲率半径。
步骤2、制作CF基板1与Array基板2。
请同时参阅图4、图5,该步骤2与现有的曲面液晶面板制作方法中制作CF基板与Array基板的过程相同,即采用平板涂布方式制作CF基板1与Array基板2。完成该步骤2后,所述CF基板1与Array基板2均呈平面状态。且所述CF基板1与Array基板2上具有相互对应的显示区域5。
该步骤2包括了在所述CF基板1或Array基板2上围绕显示区域5涂覆一圈框胶6,并将液晶滴入所述框胶6内形成液晶层3。涂覆框胶6也与现有的曲面液晶面板制作方法中涂覆框胶的过程相同,即采用平板涂布方式涂覆框胶6。
值得注意的是,该步骤2中CF基板1上的黑色矩阵11、及光阻间隔物4不同于现有的CF基板。
具体的,该步骤2采用合理设计的光罩22曝光BM光阻从而将所述黑色矩阵11制作于CF基板1上,且黑色矩阵11呈阵列式排布。针对一种特定曲率的液晶面板只需一种光罩22来进行曝光,不需增加额外的成本。所述Array基板2上制作有数条数据线21,且所述数条数据线21等间距排列。此时,在CF基板1与Array基板2均处于平面状态时,根据步骤1中预设的曲率半径将每相邻两条数据线21之间的间距L2与黑色矩阵11在数据线21排列方向上的间隔L1设计为不相等,不同于现有的基板中将黑色矩阵11在数据线21排列方向上的间隔L1与每相邻两条数据线21之间的间距L2设置为相等。
进一步的,本实施例将L2与L1设置成比例关系,设所述CF基板1的预设曲率半径为R,CF基板1与Array基板2之间的液晶层3的盒厚为d,其中R为处于曲面状态下的CF基板1的圆心到其靠近液晶层3一侧表面的距离,则当该曲面液晶面板设定为朝向CF基板1一侧弯曲时,Array基板2的预设曲率半径相应为R+d,即曲面状态下的Array基板2的圆心到其靠近液晶层3一侧表面的距离,则设置L1:L2=R:(R+d);当该曲面液晶面板设定为朝向Array基板2一侧弯曲时,Array基板2的预设曲率半径相应为R-d,则设置L1:L2=R:(R-d)。
同时,所述CF基板1上还制作有多个光阻间隔物4,根据步骤1中预设的CF基板的曲率半径将位于CF基板1不同位置处的光阻间隔物4的高度设置为不等,不同于现有的曲面液晶面板制作方法中将位于CF基板不同位置处的光阻间隔物的高度设置为相等。此时,在CF基板1与Array基板2在平面状态时,位于CF基板1中间位置的光阻间隔物4比位于两侧位置的光阻间隔物4的高度高。这样设置光阻间隔物4的目的在于,当完成后续步骤3、步骤4,分别对所述CF基板1、Array基板2进行弯曲,并以曲面贴合方式进行真空贴合,形成曲面液晶面板后,CF基板1与Array基板2的中间位置所承受的应力与受挤压的程度大于两侧位置所承受的应力与受挤压的程度,而将位于CF基板1中间位置的光阻间隔物4设置为比位于两侧位置的光阻间隔物4的高度高,可使得位于CF基板1中间位置的光阻间隔物4比位于两侧位置的光阻间隔物4能承受更大的应力,使得位于CF基板1不同位置处的光阻间隔物4的高度相同,从而所述CF基板1与Array基板2之间得以保持等间距,保证曲面液晶面板整体的液晶层3的盒厚一致。
步骤3、分别对所述CF基板1、Array基板2进行弯曲,以达到步骤1中预设的曲率半径。
该步骤3明显不同于现有的曲面液晶面板制作方法中先将CF基板与Array基板对组形成平板液晶面板,再将整个平板液晶面板进行弯曲的过程,而是先分别弯曲CF基板1、Array基板2至预设的曲率半径。
步骤4、将弯曲后的CF基板1与Array基板2以曲面贴合方式进行真空贴合,形成曲面液晶面板。
在完成步骤3分别对所述CF基板1、Array基板2进行弯曲后,该步骤4采用曲面贴合方式进行贴合,实现弯曲的CF基板1与Array基板2的对组。如图6、图7所示,由于步骤2中对黑色矩阵11、光阻间隔物4做了合理设计,所述CF基板1与Array基板2在曲面状态下,所述黑色矩阵11沿曲面液晶面板弯曲方向与每一数据线21在曲面液晶面板的径向上重合,使得Array基板2与CF基板1的像素区域相匹配,从而能够避免漏光缺陷;位于CF基板1不同位置处的光阻间隔物4对Array基板2的顶压效果相同,从而不同位置处的光阻间隔物4的高度相同,使得不同位置处的液晶层3的盒厚相同,避免了由液晶层3的盒厚不均造成的显示缺陷。
若需要将大尺寸的曲面液晶面板切割为小尺寸,本发明的曲面液晶面板的制作方法还包括步骤5、对真空贴合后的CF基板1与Array基板2进行切割。
具体的,如图8所示,该步骤5采用竖版切割方式进行切割。所谓竖版切割,即将曲面液晶面板立起来进行切割,减少切割对曲面液晶面板的曲率半径造成的影响。
综上所述,本发明的曲面液晶面板的制作方法,使CF基板与Array基板分别弯曲后,再在曲面状态下贴合、切割,并对黑色矩阵、光阻间隔物进行合理设计。该方法不同于现有曲面液晶面板的制作方法中对整个平板液晶面板进行弯曲,解决了平板液晶面板弯曲过程中由于CF基板与Array基板的相对移动所导致的黑色矩阵位移、光阻间隔物高度不同的问题,避免了现有曲面液晶面板制作方法造成的显示缺陷,有效提高产品良率,且制程简便、不增加额外成本。
以上所述,对于本领域的普通技术人员来说,可以根据本发明的技术方案和技术构思作出其他各种相应的改变和变形,而所有这些改变和变形都应属于本发明权利要求的保护范围。
