Description

液晶显示装置用摩擦装置
技术领域
本发明涉及液晶显示装置用摩擦装置,特别是涉及改善了配置基板的载物台的摩擦装置。
背景技术
通常,液晶显示装置(以下称为LCD)工序中,液晶单元工序是,在形成滤色层及通用电极的滤色基板和形成薄膜晶体管(以下称为TFT)及象素电极的TFT基板之间注入液晶,添加驱动电路,可进行图像显示的液晶单元状态进行制造的工序。这样的液晶单元工序可分为:用于液晶分子的取向膜形成工序、单元间隙形成工序及粘附偏光薄膜的工序等。
其中,取向膜形成工序通常是人为地在基板上形成有机高分子膜,机械地摩擦处理的方法,此时,摩擦工序是指,在基板上涂敷聚酰亚胺(Polyimide)系高分子化合物,形成均匀的膜,然后,利用机械摩擦装置以一定的方向摩擦。当进行这样的摩擦时,基板上的液晶分子沿摩擦方向排列。
用于摩擦工序的摩擦装置具有载置平坦基板的载物台和摩擦基板的辊。
图1表示现有的摩擦装置摩擦基板时的平面。
如图1所示,摩擦装置具有载物台110和辊120。当在载物台110上放置基板130时,辊120沿一定的方向摩擦基板130。
但是,初期,辊120为摩擦基板130而在基板130上移动时,形成于基板130和载物台110之间的一定高度的颚部会损伤包围由棉或人造(rayon)系纤维的毛构成的辊120的摩擦布,损伤时产生的异物散布在基板130上。特别是在基板130的端部不平坦时,会有大量的异物散布在基板130上。当这样的异物散布在基板130上时,会产生LCD的品质降低的问题。因此,为除去散布的异物,先除去形成于基板130上的取向膜后再进行摩擦。这样的再操作造成了使制造LCD时所需要的时间和费用增加的问题。
发明内容
因此,本发明是鉴于所述问题点而开发的,其目的在于,提供一种摩擦装置,可通过改善载置基板的载物台减少制造LCD时所需要的费用和时间,制造高品质的LCD。
本发明的实施例的液晶显示装置用摩擦装置包括:载物台,其载置有基板;辊,其打磨涂敷于所述基板上的化合物膜,形成取向膜,其中,所述载物台包括:吸附装置,其吸附所述基板,并可垂直移动;台阶缓和装置,其包围所述基板的外端侧,可上下左右移动。
在使用本发明的摩擦装置时,通过减少包围辊的摩擦布损伤时产生的异物散布在基板上,可减少为除去散布的异物而所需要的时间和费用,可制造高品质的LCD。

具体实施方式
下面,参照附图详细说明本发明实施例的LCD用摩擦装置。
图2A是表示本发明的摩擦装置摩擦基板时的剖面图。
如图2A所示,摩擦装置具有载物台210和辊220,在摩擦装置的载物台210上载置有基板230。
载物台210具有台阶缓和器211和吸附器213。台阶缓和器211具有与基板230的侧面接触的部分形成得高的倾斜面,在辊220为打磨衬底230而在基板230上移动时,形成于基板320和载物台210之间的一定高度的颚部得到缓和。台阶缓和器211可选择如橡胶(Rubber)或聚四氟乙烯(Teflon)等的弹性原材料,也可选择向弹性原材料中添加高分子或金属粒子的原材料。由此,与现有的情况不同,摩擦时由基板230的端部产生的异物的散布被显著地降低。另外,吸附器212通过吸入口213吸附基板230,其通过在摩擦时辊220施加在基板230上的压力上下移动。
下面是摩擦装置摩擦基板230的一连串过程。
首先,吸附器212通过吸入口210吸附基板230。即,将基板230载置在载物台210上。然后在基板230的端部外侧配置台阶缓和器211,然后,辊220经由台阶缓和器211从载物台210上移动到基板230上。当移动的辊220摩擦基板230时,在基板230上液晶分子的初期排列方向被决定。在辊220摩擦基板230时,通过辊220施加在基板230上的压力使吸附器212上下移动。
图2B是表示本发明的摩擦装置摩擦基板时的平面图。
如图2B所示,摩擦装置具有载物台210和辊220,在摩擦装置的载物台210上载置有基板230。台阶缓和器211包围基板230的端部。
摩擦装置摩擦基板230的一连串过程如前面所说明。
图3是本发明的摩擦装置的另一实施例,表示摩擦装置的台阶缓和器可根据基板的大小调整的情况。
如图3所示,摩擦装置具有载物台310和辊320,在摩擦装置的载物台310上载置有基板330。特别是台阶缓和器311,根据基板330的大小排列,其各侧面能够以条(bar)的状态分离开,水平或垂直地移动调整包围基板330的端部。
摩擦装置摩擦基板330的一连串过程如上面所说明。
下面,在比较现有的装置和本发明的装置之后,对本发明的优越性进行说明。
在图1所示的现有摩擦装置中,辊直接经过形成于基板和载物台之间的一定高度的颚部,移动到在基板上。其结果是颚部造成包围辊的摩擦布损伤,损伤时产生的异物散布在基板上。
但是,在图2所示的本发明的摩擦装置中,形成于基板和载物台之间的一定高度的颚部通过台阶缓和器被缓和。即,由于辊通过台阶缓和器移动到基板上,故可防止颚部造成包围辊的摩擦布损伤,结果减少损伤时产生的异物的散布。
以上通过实施例详细地说明了本发明,但本发明不限于实施例,具有本发明在所属的技术领域的通常的知识的方法的技术人员可不脱离本发明的思想和精神对本发明进行修改或变更。
