Description
技术领域
本发明涉及液晶显示面板的光配向技术领域,具提涉及一种光配向设备。
背景技术
现有的液晶显示器大部分为背光型液晶显示器,其包括壳体、设于壳体内的液晶面板及设于壳体内的背光模组。通常液晶面板由一彩色滤光片基板(Color Filter,CF)、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,其工作原理是通过在CF基板和TFT基板上施加驱动电压来控制液晶层的液晶分子的旋转,控制光的输出量,将背光模组的光线折射出来产生画面。
在液晶显示面板的制作过程中,对配向膜进行配向是一项重要工艺,通过配向工艺来实现液晶分子按照特定的方向与角度排列。在TFT-LCD生产中,有两种配向方法:摩擦配向和光配向。摩擦配向为物理方法,会产生静电和颗粒的污染。光配向是一种非接触式的配向技术,利用线偏振光透过光罩照射在对光敏感的高分子聚合物配向膜上,在配向膜表面形成一定倾斜角度的配向微结构达到配向效果。
图1为现有技术的光配向机台的示意图,机台104上方设置支架105,支架105上设置有配向光源101,配向光源101经过滤光片102以及偏光片103,获得固定偏振方向的直线偏振光。由于直线偏振光的偏振方向会决定配向膜(液晶)的配向方向,而不同的基板设计需要配向膜不同的配向方向。在偏振光方向不能变化的情况下,一般是通过旋转基板106,玻璃长边扫描照光或者短边扫描照光;如果是长边进入,则需要增大配向光源101、滤光片102、偏光片103以及机台的尺寸,从而会增加成本。
因此,需要提供一种新的光配向设备,能够在不增加各部件尺寸的条件下,满足对不同类型液晶显示面板的配向膜进行配向。
发明内容
本发明提供一种光配向设备,能够在不改变各部件尺寸的条件下,对不同类型液晶显示面板的配向膜进行配向,以解决当不同配向需求的基板进入配向设备之前,需要将基板进行旋转,基板以长边进入时需要增加机台和各部件的尺寸,进而增加设备成本的技术问题。
为解决上述问题,本发明提供的技术方案如下:
本发明提供一种光配向设备,包括机台,所述机台上传送有待配向基板,所述机台上方设置有:
配向光源,用于放出液晶配向光;
偏光片,位于所述配向光源下方,使进入的光形成偏振光射出;以及
扭曲向列型液晶盒,位于所述偏光片下方,用于控制透过的光的偏振方向;
其中,所述扭曲向列型液晶盒包括:
上基板,其下表面设置有公共电极层;
下基板,与所述上基板相对设置,其上表面设置有薄膜晶体管阵列以及像素电极层;以及
液晶层,夹设与所述上基板与下基板之间。
根据本发明一优选实施例,所述上基板的下表面设置有上配向膜,所述下基板的上表面设置有下配向膜,所述上配向膜表面的取向沟槽与位于所述下配向膜表面的取向沟槽相互垂直,所述液晶层位于所述上配向膜与所述下配向膜之间。
根据本发明一优选实施例,当所述扭曲向列型液晶盒不加电压时,所述液晶层中的液晶分子的长轴平行于所述上配向膜与下配向膜,且单个像素中的液晶分子纵向分布,且自上而下逐渐旋转至90度;当所述扭曲向列型液晶盒加电压时,所述液晶层中的液晶分子的长轴均垂直于所述上配向膜与下配向膜。
根据本发明一优选实施例,所述光配向设备所述还包括一滤光片,所述滤光片位于所述配向光源下方,用于根据实际需求过滤掉指定波长的光。
根据本发明一优选实施例,所述滤光片用于过滤掉波长240~370nm以外的紫外光。
根据本发明一优选实施例,所述机台位于所述扭曲向列型液晶盒的下方,所述机台上移载有涂抹聚酰亚胺液的玻璃基板。
根据本发明一优选实施例,所述光配向设备还包括一横向设置的导光板,所述导光板的一侧为入光面,所述配向光源的发光面接近所述导光板的入光面设置,所述导光板的下表面为出光面,所述出光面位于所述偏光片上方并平行于所述偏光片。
根据本发明一优选实施例,所述导光板的上表面贴设有反射片。
根据本发明一优选实施例,所述配向光源为微波紫外灯。
根据本发明一优选实施例,所述微波紫外灯的功率至少为900MHz。
本发明的有益效果为:本发明相较于现有的光配向设备,能够根据配向需求来调节配向光的偏振方向,从而不需要旋转基板就能对不同配向需求的配向膜进行配向;解决了现有技术的光配向设备,兼容性较弱,配向光不可调节,当具有不同配向要求的基板进入设备时需要旋转90度以长边进入,从而需要增加机台及各部件的尺寸以满足该基板的光配向,进而增加了设备成本的技术问题。
附图说明
为了更清楚地说明实施例或现有技术中的技术方案,下面将对实施例或现有技术描述中所需要使用的附图作简单介绍,显而易见地,下面描述中的附图仅仅是发明的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下,还可以根据这些附图获得其他的附图。

具体实施方式
以下各实施例的说明是参考附加的图示,用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语,例如[上]、[下]、[前]、[后]、[左]、[右]、[内]、[外]、[侧面]等,仅是参考附加图式的方向。因此,使用的方向用语是用以说明及理解本发明,而非用以限制本发明。在图中,结构相似的单元是用以相同标号表示。
本发明针对现有的光配向设备,兼容性较弱,配向光不可调节,当具有不同配向要求的基板进入设备时需要旋转90度以长边进入,从而需要增加机台及各部件的尺寸以满足该基板配向膜的光配向,导致设备成本增加的技术问题,本实施例能够解决该缺陷。
如图2所示,本发明的光配向设备,包括有机台201,所述机台201内设置有传送部及夹持部,所述夹持部一侧与所述传送部固定连接,待配向基板208从所述机台201的入口处进入,所述待配向基板208的一侧被所述夹持部夹持固定,然后经由所述传送部将所述待配向基板208送至配向光源的下方,最后将配向完成后的基板送入下一制程。
所述待配向基板208为液晶显示面板的阵列基板或彩膜基板,所述阵列基板与彩膜基板的表面均设置有一层配向膜,在待配向基板208进入光配向设备之前,所述配向膜表面会涂布用于与配向光发生反应以完成配向的感光剂;部分类型的液晶显示面板,位于所述阵列基板上的配向膜表面的取向沟槽与位于所述彩膜基板上的配向膜表面的取向沟槽方向相差90度(正交),因此在进行配向时有一基板需要旋转90度才能受到正确方向的扫描照光。
所述机台201的上部设置有一支架202,所述支架202上设置有配向光源203、偏光片204以及扭曲向列型液晶盒205(Twisted Nematic Liquid Crystal Display,TN-LCD);所述配向光源203为微波紫外灯,用于放出配向光,所述配向光源203位于所述支架202靠上的位置;所述偏光片204位于所述配向光源203下方,使进入的光形成偏振光射出;所述扭曲向列型液晶盒205,位于所述偏光片204下方,用于控制透过的光的偏振方向。
优选的,所述配向光源203与所述偏光片204之间设置有滤光片206,所述滤光片206用于过滤掉一些不需要的光线,留下指定波长的光以配合实际配向需求;例如,使用所述滤光片206过滤掉波长为240~370nm以外的紫外光。
优选的,所述203外侧设有灯罩207,以扩大光照范围,且使光扩散均匀。又如,所述光配向设备还包括一横向设置的导光板,所述导光板的一侧为入光面,所述203的发光面接近所述导光板的入光面设置,所述导光板的下表面为出光面,所述出光面位于所述偏光片上方并平行于所述偏光片;所述导光板使所述203发出的光均匀分散,以充分利用配向光。
优选的,所述导光板的上表面贴设有反射片,所述反射片用以将配向光向下反射至所述偏光片。
如图3所示,为图2中扭曲向列型液晶盒的放大结构示意图,所述扭曲向列型液晶盒包括有上基板301、下基板302,所述上基板301与所述下基板302相对设置,所述上基板301与所述下基板302之间夹设有液晶层303,所述液晶层303外侧设置有框胶304,所述扭曲向列型液晶盒的下方不设置偏光片;所述上基板301表面设置有公共电极层307,所述下基板302表面设置有若干薄膜晶体管305以及一像素电极层306,向所述像素电极层306与所述公共电极层307之间施加电压以改变液晶层303的形态,进而可控制光的通过率。
所述扭曲向列型液晶盒的上基板301的下表面设置有上配向膜308,所述下基板302的上表面设置有下配向膜309,根据扭曲向列型液晶盒的特性,所述上配向膜308表面的取向沟槽与位于所述下配向膜309表面的取向沟槽方向相互垂直,所述液晶层303位于所述上配向膜308与所述下配向膜309之间。
如图4所示,为图3的扭曲向列型液晶盒中的液晶分子在不通电状态下的活动规律,图中包括公共电极层401、位于公共电极层401下表面的上配向膜402以及像素电极层403、位于所述像素电极层403上表面的下配向膜404,所述液晶层中的液晶分子沿上配向膜402及下配向膜404排列,液晶分子405的长轴在不加电的状态下与上基板、下基板相平行,并且液晶分子405从上基板至下基板之间逐渐扭转90度排列,所述液晶层夹入上基板与下基板之间,制成所述扭曲向列型液晶盒,因此,所述配向光源发出的光线经位于其下方的偏光片变成线偏振光,入射到所述扭曲向列型液晶盒内,光被扭曲90度后射出。
如图5所示,为图3的扭曲向列型液晶盒中的液晶分子在通电状态下的活动规律,图中包括公共电极层501、位于公共电极层501下表面的上配向膜502以及像素电极层503、位于所述像素电极层503上表面的下配向膜504,所述液晶层中的液晶分子505沿上配向膜502及下配向膜504排列,当两电极之间加上一定的电压时,每个液晶分子505的长轴旋转90度,与所述上基板、下基板呈垂直排列,入射光透过液晶盒内的偏振光,未被扭曲,使得射出的光线保持原偏振方向。
本发明的光配向设备,利用了扭曲向列型液晶盒的旋光特性,液晶分子长轴90度扭曲导致了90度的旋光,当加电压时,液晶分子将随电场方向排列,扭曲结果消失,导致旋光作用消失,透过的光不作偏振变化,通过控制光的两种偏振方向,能够满足对不同配向需求的基板进行光配向;机台及其他的部件的尺寸不需改变,两种配向需求的基板均可以短边进入机台,只需控制配向光的偏振方向来适配不同基板的配向需求。
综上所述,虽然本发明已以优选实施例揭露如上,但上述优选实施例并非用以限制本发明,本领域的普通技术人员,在不脱离本发明的精神和范围内,均可作各种更动与润饰,因此本发明的保护范围以权利要求界定的范围为准。
