Description

固化框胶用遮光翠的制作方法
本发明涉及显示领域, 尤其涉及一种固化框胶用遮光罩的制作方法。 背景技术
框胶是应用于液晶显示面板的一种接着剂, 其用途是将薄膜晶体管基 板和彩色滤光片基板两片玻璃基板结合在一起, 避免注入两片玻璃基板之 间的液晶材料流出。 请参阅图 1, 为现有的液晶显示面板的结构示意图, 其中, 密封胶框 loo就是由框胶经由固化形成的。
过去的制程是先在配向膜上面形成间隔物 (Spacer ) , 再将玻璃基板 用框胶粘合在一起, 做成空的液晶盒。 后来随着面板的尺寸朝大型化发 展, 采用液晶滴下法(One Drop Filling, ODF ) 的比例逐渐扩大, 制造程 序上做了一些改变, 于是框胶的性质也在变化之中。
框胶可以分为热硬化型和激光 ( UV )硬化型两大类, 目前的 ODF制 程基本釆用 UV硬化型的框胶, 在新生产线均采用 ODF制程的情¾下, UV硬化型的框胶将成为主流。 UV硬化型的框胶内含光起始剂、 紫外线接 着剂等成份。 UV 光被光起始剂吸收, 造成光起始剂引发产生自由基或阳 离子反应基, 这些具有高度反应性的自由基或阳离子基, 与组成内的压克 力单体或环氧基单体以及相对应的寡聚物进行链延长反应。 由于自由基反 应或阳离子基反应的反应性非常快, 在几秒至几分钟内反应物就完成反 应, 形成具有物性的高分子聚合物。 UV 紫外线接着剂特性是借由 UV 光 源照射起动化学连锁反应, 固化框胶。 在数秒内即可固化粘合材质。
对液晶显示面板进行整体 UV 照射, 会造成面板构成中的某些材料成 分发生质变, 影响材料性能, 最终影响液晶显示面板的品质和良率。 所 以, 通常会有选择地针对框胶进行 UV 照射和 UV硬化, 不需要进行 UV 照射的区域就要通过遮光的挡板遮挡起来, 该功能由遮光罩实现。 请 参阅图 2, 遮光罩一般包括: 图形部 300及设于图形部 300***的遮光部 500 , 在对液晶显示面板的框胶进行 UV 固化时, UV 紫外线通过图形部 300 照射于框胶上, 对框胶进行固化, 遮光部用于遮挡 UV 紫外线, 以免 UV紫外线对液晶显示面板的其他材料照射, 而导致该材料质变。
不同尺寸、 不同型号的液晶显示面板, 其框胶的设置位置不尽相同, 这就使得, 不同尺寸、 不同型号的液晶显示面板需要相应的不同尺寸、 不 同型号的遮光罩与之对应。
请参阅图 3 至图 6, 现有的固化框胶用遮光罩的制作方法一般为: 首 先, 在基.板 700 上涂布金属层 702、 光阻层 704; 接着, 通过掩模板 750 在光阻层 704上曝光出預定图形; 然后, 进行显影、 蚀刻及光阻剥离; 最 后, 在形成的图形上涂布非金属保护层 706。 其中, 在对光阻层 704进行 曝光时, 所需要的掩模板 750上的图形需要与预定图形的大小相同, 这就 使得, 在制作不同尺寸、 不同型号的固化框胶用遮光罩时, 所需要不同的 掩模板; 即, 每一种尺寸、 每一种型号的固化框胶用遮光罩需要至少一对 应的掩模板, 生产成本较高, 且不宜进行统一管理。 发明内容

由于挡板 44的遮挡, 所述穿过图形区 422的 UV光不能照射到光阻 层 24上, 所以掩模板 42上的图形区 422上的图形不能复制到光阻层 24 上, 这就使得对光阻层 24的曝光与掩模板 42上的图形无关, 那么, 只要 所选用的掩模板 24 的尺寸与所要制得的遮光罩的尺寸大小相对应即可实 现生产, 避免了现有的生产制程中必需配置相应图形区的掩^ I板才能实现 生产的困扰, 有效减少掩模板的预备数量, 进而降低生产材料成本, 同 时, 由于预备的掩模板的数量较少, 易统一管理, 存储, 降低管理及存储 成本。
步骤 4、 釆用边曝光方式, 按照预定路径对光阻层 24进行曝光, 所述 预定路径对应液晶显示面板的框胶 i¾设路径。
具体地, 请参阅图 10, 所述步骤 4 包括: 提供边曝光设备 60, 按照 预定路径对应光阻层 24进行曝光„ 在本实施例中, 所述边曝光设备 60为 边曝光机。
边曝光机按照预定路径在光阻层 24 上曝光出预定图形, 该过程相当 于用边曝光机在光阻层 24上按照预定路径画出預定图形。
步骤 5、 去除被曝光的光阻层 24, 以露出金属层 22。
请参阅图 11, 去除被曝光的光阻层 24, 以露出金属层 22。
步骤 6、 对露出的金属层 22进 蚀刻, 并去除未曝光的光阻层 24。 请参阅图 12及图 13 , 所述蚀刻可为千蚀刻与湿蚀刻其中之一或其组 合, 具体操作时, 可根据金属层 22的材料不同选择相应的蚀刻方式。
步骤 7、 在金属层 22与透明基板 20上形成透明保护层 26。
请参阅图 14, 所述透明保护层 26 由非金属材料形成, 其通过化学气 相沉积方式形成, 用于保护金属层 22 , 以避免金属层 22被氧化或侵蚀, 进而延长遮光罩的使用寿命。
综上所述, 本发明的固化框胶用遮光罩的制作方法, 通过边曝光方式 按照預定路径实现对光阻层的图案化曝光, 不需要特定的掩模板, 有效减 少掩模板的预备量, 降低生产材料成本, 同时, 由于掩模板的预备量较 少, 易统一管理、 存储, 降低管理及存储成本。
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。
