Description

用于液晶面板的混切玻璃基板及其涂胶方法 技术领域
本发明是有关于一种用于液晶面板的混切玻璃基板及其涂胶方法，特别是有关于一种能够防止在液晶面板制程中因翻转作业导致产品不良的混切玻璃基板及其涂胶方法。

在液晶面板制作过程中，面板(panel)由分别含有彩色滤光片(CF)与薄膜晶体管(TFT)的两片玻璃基板组装而成。例如：依序进行ODF(One Drop Filling)、VAS(Vacuum Assembly System)、SUV、SMO、PSVA(Polmer Stabilized Vertivally Aligned)等制程，以便进行框胶涂布、真空对组、框胶照光固化、框胶热固化及垂直排列液晶等过程，使液晶被密封在所述两片玻璃基板之间。
举例而言，如图1所示，框胶涂布过程可由一框胶滴头N在一玻璃基板T涂布多个框胶E，用于裁切后进行面板组装。在实际生产过程中，玻璃基板T会在SUV与SMO制程之间进行翻转，如图2所示，利用一翻转夹棍(bar)B将所述玻璃基板T进行翻转180度。

请参照图3所示，本发明的一方面提供一种用于液晶面板的混切玻璃基板涂胶方法，可包括以下步骤：获取一玻璃板材T，所述玻璃板材T上具有数个框胶E1~E4(以四个为例，但不以此为限)，所述数个框胶E1~E4之间形成数个相互交会的径道L1~L4，所述数个框胶E1~E4中的至少两个的对角线尺寸不同，例如：框胶E1、E2的对角线尺寸不同，框胶E3、E4的对角线尺寸不同；在所述对角线尺寸不同的框胶E1~E4之间形成的径道L1~L4处定义一虚拟图案(dummy pattern)P，所述虚拟图案P包括至少一条线段；及在所述虚拟图案P处涂布一胶体，例如：所述胶体与所述框胶E1~E4的材料相同，所述的材料可为现有框胶材料，但是所述胶体也可依实际需求换成其他材料，在此并不设限。以下举例说明上述方法的实施方式，但不以此为限。
举例来说，如图3所示，在所述玻璃板材T中，假设所述框胶E1、E3的对角线尺寸为32吋(inches)，且所述框胶E2、E4的对角线尺寸为65吋，在所述框胶E2、E4之间的径道L4的宽度大于其它径道L1~L3的宽度，在所述对角线尺寸不同的框胶E1~E4之间形成的径道L1~L4处可定义所述虚拟图案P，所述虚拟图案P可位于所述径道L1~L4之间的一虚拟区域S内，使得所述虚拟图案P包括至少一条线段，诸如：直实线(straight solid line)、直虚线(或称直的间断线，straight dashed line)、锯齿线(或称迂回连接线，zigzag line)、曲线(curve)、弧线(arc)或其结合，以便后续在所述虚拟图案P处涂布所述胶体。
例如：所述线段与所述框胶E1~E4的边缘之间具有一最小间距d，所述最小间距大于2毫米，以避免所述虚拟图案P与面板的切割线重合。另，所述线段的宽度w具有一范围，所述范围可为100至2000微米，诸如：500、100、1500微米等，以避免涂胶范围过小。又，所述线段具有二端，所述二端之间具有一最小连线距离，所述最小连线距离比位在所述虚拟图案P两侧的所述框胶(如E1、E2)中的一对角线尺寸较大者(如框胶E2)的一边缘更短，且所述线段从所述数个框胶中的一个(如框胶E2)周围延伸到所述数个框胶中的另一个(如框胶E4)周围，以确保涂胶区域横跨不同对角线长度的框胶之间的一拼接区域。以下举例说明所述虚拟图案P的一些实施方式，但不以此为限。
在一些实施例中，如图4A及图4B所示，所述虚拟图案P可包括下列形态，以单一直实线为例，所述单一直实线可与所述框胶E1~E4的一横向边缘平行(如图4A所示)；或者，所述单一直实线可与所述框胶E1~E4的一纵向边缘平行(如图4B所示)。替代地，所述单一直实线可被换成多条直实线，例如：相互平行的直实线；另一方面，所述直实线也可被换成所述的直虚线(如图4C所示)或曲线(如图4D所示)。
从而，所述虚拟图案P处涂布的胶体可适用于只有两个框胶所围成的直线状径道，或由三个框胶所围成的类T字状径道，用以加强所述多个框胶之间的结构强度。
在一些实施例中，如图4E至图4G所示，所述虚拟图案P可包括下列形态，以数条直实线或直虚线为例，所述数条直实线或直虚线可相互垂直，例如：所述数条直实线或直虚线中的一条的一端连接在另一条的两端之间，诸如形成一个类T字状(如图4E所示)；替代地，所述数条直实线或直虚线也可互不连接；替代地，所述数条直实线或直虚线中的一条的一端连接在另一条的一端，诸如形成至少一直角(如图4F所示)；替代地，所述数条直实线或直虚线可相互交叉，诸如形成一个类十字状(如图4G所示)。
从而，所述虚拟图案P处涂布的胶体可适用于由三个框胶所围成的类T字状的径道，或由四个框胶所围成的类十字状的径道，用以加强所述多个框胶之间的结构强度。
在一些实施例中，如图4H及图4I所示，所述虚拟图案P可包括下列形态，以四条直实线或直虚线为例，所述四条直实线或直虚线相互连接而形成一个四边形，诸如形成一正方形等(如图4H所示)；替代地，所述四边形中的线段也可向外延伸形成，诸如形成用于数独(sudoku)的九宫格或井字状(如图4I所示)。
从而，所述虚拟图案P处涂布的胶体除可适用于由四个框胶所围成的类十字状的径道，更可用以加强所述多个框胶之间的结构强度。
本发明的另一方面提供一种用于液晶面板的混切玻璃基板，所述用于液晶面板的混切玻璃基板是由如上所述的用于液晶面板的混切玻璃基板涂胶方法制成，可以完成加强所述多个框胶之间的结构强度的效果。
此外，本发明的用于液晶面板的混切玻璃基板及其涂胶方法也可以实施在一玻璃基板具有多个对角线尺寸相同的框胶，同样可以完成加强所述多个框胶之间的结构强度的效果。
与现有技术相比较，本发明上述实施例的用于液晶面板的混切玻璃基板及其涂胶方法通过在所述玻璃板材的框胶之间涂布与所述框胶相同的胶体，相较于现有未在所述对角线尺寸不同的框胶之间涂布胶体的混切玻璃基板，本发明实施例可以加强所述多个框胶之间的结构强度，在面板实际生产过程中进行翻转时，可避免多个框胶的边缘之间的角落拼接处承受过大应力，可改善现有混切玻璃基板发生脱胶，致使面板产品存在气泡，在点灯测试时产生不正常的显示区块的问题，本发明实施例可以使得面板产品可以正常通过点灯测试，可以有效改善产品良率，并可降低制造成本。
本发明已由上述相关实施例加以描述，然而上述实施例仅为实施本发明的范例。必需指出的是，已公开的实施例并未限制本发明的范围。相反地，包含于权利要求书的精神及范围的修改及均等设置均包括于本发明的范围内。
