Description

液晶面板及其制造方法
技术领域
本发明涉及一种液晶面板及其制造方法。
背景技术
近年来由于工商发达、社会进步,相对提供的产品也主要针对便利、经济实惠为主旨,因此,目前开发的产品也比以往更加进步,而得以贡献社会;在关在显示屏幕方面,近年来业者不断地开发出更经济便利的液晶面板供液晶显示器使用,使其作业与功效可达到事半功倍的运作。
目前液晶面板或液晶光学组件中都要使用配向膜,现行配向膜制程中,需将配向膜制作在基板上,再对配向膜定向摩擦,经此方法处理过的配向膜的功能是要将液晶做有序的排列,因为对液晶做有序排列的结果,可有效控制液晶排列的方向,即可得到所预期的液晶显示模式。
但是,在摩擦配向膜的时候易因施力面不同,使液晶面板的配向膜厚度不均,而产生使显示画面不均匀的液晶堆积(Mura)现象。
发明内容
为了解决现有技术中的液晶面板显示的画面不均匀的问题,有必要提供一种使显示的画面均匀的液晶面板。
为了解决现有技术中的液晶面板显示的画面不均匀的问题,也有必要提供一种使显示的画面均匀的液晶面板的制造方法。
一种液晶面板,其包括一基板、一薄膜晶体管阵列、一线路与一支撑结构。该薄膜晶体管阵列形成在基板上。该线路形成在基板上,配置在薄膜晶体管阵列的至少一侧边附近,与薄膜晶体管阵列电性连接。该支撑结构与该线路分开设置,并沿着薄膜晶体管阵列的侧边附近设在基板上。
一种液晶面板,其包括基板、一薄膜晶体管阵列、一第一线路与一第一虚设线路。该基板表面具有一显示区与一配线区,其中该配线区位于显示区外侧。该薄膜晶体管阵列形成在该基板上并配置在该显示区。该第一线路配置在该配线区并位于该显示区的一侧边附近,用以传递信号给该薄膜晶体管阵列;该第一虚设线路配置在该配线区上并位于该侧边附近的未设有该第一线路之处。
一种液晶面板的制造方法,其包含以下步骤:首先,提供一基板,该基板的表面具有一显示区与一配线区,其中该配线区位于该显示区外侧;接着,形成该薄膜晶体管阵列在该基板的显示区上;形成该第一线路与该第一虚设线路在该基板的配线区上,并将该第一线路设在该显示区的一侧边附近,且将该第一虚设线路设在该显示区的该侧边附近的未设有第一线路之处。
相较于现有技术,在配向膜制程中,将配向膜制作在设有该线路和该支撑结构的基板上,或将配向膜制作在设有该第一线路和该第一虚设线路的基板上,再对该配向膜定向摩擦。由于第一线路的间隔处设有该支撑结构或者该第一虚设线路填补,使得位于该侧边附近的配线区上的地形差异缩小,进而改善摩擦时受力不均的问题,减少液晶堆积的发生。
附图说明
图1是本发明液晶面板第一实施方式的平面示意图。
图2是沿着图1所示的线段2-2的剖面图。
图3是本发明液晶面板第二实施方式的平面示意图。
图4是沿着图3的线段4-4的剖面图。
图5是图1所示的液晶面板的制造方法的流程图。
具体实施方式
请参阅图1,其是本发明液晶面板第一实施方式的平面示意图。该液晶面板100包括一基板110、一薄膜晶体管阵列120、多个第一线路130与多个第一虚设线路140。该基板110表面具有一显示区112与一配线区113,其中该配线区113位于该显示区112外侧。该薄膜晶体管阵列120形成在该基板110上,并配置在该显示区112。该第一线路130配置在该配线区113并位于该显示区112的一侧边114附近。该第一虚设线路140配置在该配线区113上并位于该侧边114附近的未设有该第一线路130之处,其中该第一虚设线路140与该第一线路130相毗连并相应地突出于该基板110表面。
在结构上,该第一线路130电性连接该薄膜晶体管阵列120,但是该第一虚设线路140与该薄膜晶体管阵列120无电性连接关系;在使用时,该第一线路130用于传递信号给该薄膜晶体管阵列120,但是该第一虚设线路140并无传递信号的作用。举例来说,外部的集成电路可以通过该第一线路130将信号传送到该薄膜晶体管阵列120,藉以驱动该薄膜晶体管阵列120,使得该薄膜晶体管阵列120执行相应的动作。另外,该基板110可以为玻璃基板。
这样,在配向膜制程中,将配向膜制作在设有该第一线路130和该第一虚设线路140的基板110上,再顺着方向310对配向膜定向摩擦。由于该第一线路130的间隔处设有该第一虚设线路140填补,使得位于该侧边114附近的该配线区113上的地形差异缩小,进而改善摩擦时受力不均的问题,减少液晶堆积的发生。
该第一虚设线路140突出的高度符合该第一线路130突出的高度。这样,当顺着该方向310对配向膜定向摩擦时,配向膜受力更为均匀,以避免液晶堆积现象。
应了解到,在以液晶堆积不发生为前提下,该第一虚设线路140突出的高度可以略大于或略小于该第一线路130突出的高度,无须令该第一虚设线路140突出的高度完全等同于该第一线路130突出的高度,熟习此项技艺者应视当时需要弹性选择之。
请参阅图2,其是沿着图1的线段22的剖面图。如图所示,每一第一线路130都包括一第一线路图案132形成在该基板110上,每一第一虚设线路140都包括一第一虚拟图案142形成在该基板110上。这样,第一线路图案132的间隔处设有该第一虚拟图案142填补,使得该基板110上地形差异缩小。举例来说,该第一线路图案132的高度可以符合该第一虚拟图案142的高度。
每一第一线路130还包括一第一绝缘层134形成在该第一线路图案上132,每一第一虚设线路140还可包括一第一虚设绝缘层144形成在该第一虚拟图案142上。这样的话,在摩擦配向膜时可以顺向,减少液晶堆积的发生。
在图1中,该液晶面板100还可以包括多个第二线路图案152与多个第二虚拟图案162。该第二线路图案152配置在该配线区113并位于该显示区112的另一侧边115附近,并与该第一线路图案132部分相连,其中该显示区112的侧边114与另一侧边115相邻。该第二虚拟图案162配置在该配线区113上并位于该侧边115附近的未设有该第二线路150之处,其中该第二虚拟图案162与该第二线路图案152相毗连并相应地突出于该基板110表面。
这样,在配向膜制程中,将该配向膜制作在设有该第二线路图案152和该第二虚拟图案162的该基板110上,再顺着该方向310对该配向膜定向摩擦。由于该第二线路图案152的间隔处设有该第二虚拟图案162填补,使得位于该侧边115附近的配线区113上的地形差异缩小,进而改善摩擦时受力不均的问题,减少液晶堆积的发生。
实务上,小尺寸液晶面板可在基板的一侧配置线路,因而相应地在该侧配置虚设线路;大尺寸液晶面板可在基板的相邻二~四侧配置线路,因而相应地在该相邻二~四侧配置虚设线路,熟习此项技艺者应视当时需要弹性选择的。
请参阅图3,其是本发明液晶面板第二实施方式的平面示意图。如图所示,该液晶面板200的基板110、薄膜晶体管阵列120、第一线路130与第一虚设线路140实质上如同该液晶面板100,因此不再重复赘述之。除此之外,该液晶面板200还包括多个第二线路150与多个第二虚设线路160。该第二线路150配置在该配线区113并位于该显示区112的另一侧边115附近,其中该显示区112的侧边114与另一侧边115相邻。该第二虚设线路160配置在该配线区113上并位于该侧边115附近的未设有该第二线路150之处,其中该第二虚设线路160与该第二线路150相毗连并相应地突出于该基板110表面。
在结构上,该第二线路150电性连接该薄膜晶体管阵列120,但是该第二虚设线路160与该薄膜晶体管阵列120无电性连接关系;在使用时,该第二线路150可用于传递信号给该薄膜晶体管阵列120,但是该第二虚设线路160并无传递信号的作用。举例来说,外部的集成电路可以通过该第二线路150将信号传送到该薄膜晶体管阵列120,藉以驱动该薄膜晶体管阵列120,使得该薄膜晶体管阵列120执行相应的动作。
这样,在配向膜制程中,将该配向膜制作在设有该第二线路150和该第二虚设线路160的基板110上,再顺着方向320对配向膜定向摩擦。由于该第二线路150的间隔处设有该第二虚设线路160填补,使得位于该侧边115附近的配线区113上的地形差异缩小,进而改善摩擦时受力不均的问题,减少液晶堆积的发生。
该第二虚设线路160突出的高度符合该第二线路150突出的高度。这样,当顺着该方向320对该配向膜定向摩擦时,配向膜受力更为均匀,以避免液晶堆积现象。
应了解到,在以液晶堆积不发生为前提下,该第二虚设线路160突出的高度可以略大于或略小于该第二线路150突出的高度,无须令该第二虚设线路160突出的高度完全等同于该第二线路150突出的高度,熟习此项技艺者应视当时需要弹性选择的。
另外,该第一、第二虚设线路140、160突出的高度符合该第一、第二线路130、150突出的高度。这样,在配向膜制程中,可以顺着方向330对配向膜定向摩擦。由于该第一、第二虚设线路140、160突出的高度符合该第一、第二线路130、150突出的高度,使得该基板110上的地形差异缩小,进而改善摩擦时受力不均的问题,减少液晶堆积的发生。
请参阅图4,其是沿着图3的线段4-4的剖面图。如图所示,每一第二线路150都包括一第二线路图案152形成在该基板110上,其中该第二线路图案152与上述该第一线路图案可相连;每一第二虚设线路160都包括一第二虚拟图案162形成在该基板110上。
该第二线路150还可包括一第二绝缘层154形成在该第二线路图案152上,该第二虚设线路160还可以包括一第二虚设绝缘层164形成在该第二虚拟图案162上。这样的话,在摩擦配向膜时能够顺向,减少液晶堆积的发生。
该第二线路150进一步包括一第二透明导电层156配置在第二绝缘层154上,该第二虚设线路160进一步包括一第二虚设透明导电层166配置在该第二虚设绝缘层164上。举例来说,该第二透明导电层156的材料与该第二虚设透明导电层166的材料都包含氧化铟锡。
在一实施例中,可将该虚拟图案162移到该侧边114与该另一侧边115相邻处,较利于沿着该方向310与该方向330对配向膜定向摩擦。
综上所述,该液晶面板100、200可包括该基板110、该薄膜晶体管阵列120、线路与支撑结构,其中该线路可为该第一线路130与/或该第二线路150,然不以此为限;举例来说,如果该薄膜晶体管阵列120四周皆可布线时,此线路也可设在该薄膜晶体管阵列120外围。
该支撑结构可为该第一虚设线路140与/或该第二虚设线路160,然不以此为限。实作上,该支撑结构可以不是线路的型态,例如像是突出物、支撑片材或其它型态的支撑物,也都可以是支撑结构的实施方式。
在结构上,该薄膜晶体管阵列120形成在该基板110上。线路形成在该基板110上,配置在该薄膜晶体管阵列120的至少一侧边附近,与该薄膜晶体管阵列120电性连接。该支撑结构沿着该薄膜晶体管阵列120的侧边附近设在该基板上110,并与该线路分开设置。
这样,在配向膜制程中,将该配向膜制作在设有该线路和该支撑结构的基板上,再对该配向膜定向摩擦。在未布上盖线路之处设有该支撑结构,使得地形差异缩小,进而改善摩擦时受力不均的问题,减少液晶堆积的发生。
在设置上,该支撑结构与该线路相毗连。另外,该支撑结构突出的高度符合线路突出的高度。这样,当对该配向膜定向摩擦时,该配向膜受力更为均匀,以避免液晶堆积现象。
