【具体实施方式】
下面, 结合具体实施例及附图, 对本发明作出详细说明。
请参阅图 4~13 , 本发明彩色滤光片制作方法的实施例中, 包括以下步骤: 参阅图 4, 在透明基板 120上涂覆遮光涂层 121 , 该透明基板 120包括功能 区 122和间隔区 123 ;
参阅图 5, 用黑色调遮光片 124对透明基板 120上的遮光涂层 121曝光; 参阅图 6, 显影去除不必要的遮光区域, 得到黑色矩阵 125; 于一般设计, 通常将间隔区 123 的黑色矩阵去除, 故本实施例通过显影去除不必要的遮光区 域, 得到位于功能区 122的黑色矩阵 125;
参阅图 7 , 在覆有黑色矩阵 125的透明基板 120上涂覆红色滤光涂层 126; 参阅图 8,用灰色调遮光片 127对位于功能区 122之红色滤光涂层 126进行 100%强度的紫外照射,而对位于间隔区 123之红色滤光涂层 126进行 30%~50% 强度的紫外照射;
参阅图 9 , 显影去除不必要的红色滤光单元区域, 在功能区 122得到梯形的 第一红色滤光单元 128a, 在间隔区 123得到倒梯形的第二红色滤光单元 130a; 梯形靠近透明基板 120方向的边长大于远离透明基板 120方向的边长, 倒梯形 靠近透明基板 120方向的边长小于远离透明基板 120方向的边长;
重复图 7〜图 9的步骤, 仅仅将涂覆的滤光涂层颜色进行更换, 涂覆绿色滤 光涂层得到位于功能区 122 的梯形状的第一绿色滤光单元 128b 和位于间隔区 123 的倒梯形状的第二绿色滤光单元 130b, 涂覆蓝色滤光涂层得到位于功能区 122的梯形状的第一蓝色滤光单元 128c和位于间隔区 123的倒梯形状的第二蓝 色滤光单元 130c。
如图 10所示, 通过上述的三次曝光显影, 得到包括呈梯形状第一红色滤光 单元 128a、第一绿色滤光单元 128b和第一蓝色滤光单元 128c , 以及得到呈倒梯 形状第二红色滤光单元 130a、第二绿色滤光单元 130b和第二蓝色滤光单元 130c。
参阅图 11〜12: 在第一红色滤光单元 128a、 第一绿色滤光单元 128b和第一 蓝色滤光单元 128c, 以及得到呈倒梯形状第二红色滤光单元 130a、 第二绿色滤 光单元 130b、 第二蓝色滤光单元 130c及黑色矩阵 125上整体镀上导电层 129。
上述提到的 100%强度, 是指紫外光线的强度刚好将彩色滤光涂层照射完 全, 使其表面和内部都刚好固话, 从而在显影时得到截面为梯形状的彩色滤光 单元。 而 30%~50%强度, 是指紫外光线的强度不能完全将彩色滤光涂层照射完 全, 其底层只吸收部分紫外光线, 这样在显影时得到截面为倒梯形的彩色滤光 单元。
位于功能区 122之彩色滤光涂层 126与位于间隔区 123之彩色滤光涂层 126 因被不同光波能量的紫外光照射产生不同形状的彩色滤光单元的原理为: 光波 射入光阻表面时, 表层会先针对各波长将光能吸收, 进行反应, 待反应完成后, 不再进行各波长能量吸收, 底层才有机会将剩余能量吸收, 进行反应, 因而可 由此原理控制射入光波能量, 以达到表层交连完整, 底层交连不完整, 进而控 制彩色滤光单元的形状。
以上可以了解, 区别于现有技术的彩色滤光片和薄膜晶体管阵列在组装过
程中间隔区存在导电颗粒而形成彩色滤光片共电位异常的缺陷, 本发明在形成 彩色滤光单元时, 通过用灰色调遮光片 127对功能区 122和间隔区 123进行不 同程度的紫外照射, 使得功能区 122得到的第一彩色滤光单元 128为梯形, 而 间隔区 123第二彩色滤光单元 130为倒梯形, 然后在形成导电层 129时, 间隔 区 123的倒梯形的第二彩色滤光单元 130上覆盖的导电层 129为不连续形态, 形成隔绝效果。 当彩色滤光片和薄膜晶体管阵列在组装过程中, 间隔区 123 即 使存在导电颗粒时, 由于间隔区 123的导电层 129不连续, 不会有彩色滤光片 共电位异常的情况发生, 从而可以防止彩色滤光片和薄膜晶体管阵列组装异常 短路, 进而提高产品质量。
上述的黑矩阵 125是通过有机光阻材料或碳黑树脂制成。
上述的导电层 129—般由氧化铟锡制成的透明导电层。
请参阅图 12, 本发明彩色滤光片的实施例中, 包括:
透明基板 120、 黑色矩阵 125、 多个第一彩色滤光单元 128、 多个第二彩色 滤光单元 130和导电层 129 , 所述透明基板 120包括功能区 122和间隔区 123 ; 所述透明基板 120的功能区 122上设置有网格状的黑色矩阵 125 ,在黑色矩 阵 125的网格中设有第一彩色滤光单元 128,所述第一彩色滤光单元 128呈梯形, 所述梯形靠近所述透明基板 120方向的边长大于远离透明基板 120方向的边长; 透明基板 120的间隔区 123上设置有第二彩色滤光单元 130,所述第二彩色 滤光单元 130呈倒梯形, 所述倒梯形靠近所述透明基板 120方向的边长小于远 离透明基板 120方向的边长;
导电层 129覆盖于所述黑色矩阵 125和所述第一彩色滤光单元 128及第二 彩色滤光单元 130上, 且所述导电层 129覆盖于第一彩色滤光单元 128和黑色 矩阵 125部分是连续的, 导电层 129在相邻的第二彩色滤光单元 130间是不连 续的。
继续参见图 12, 第一彩色滤光单元 128至少覆盖黑色矩阵 125的一部分。 为了防止彩色滤光片漏光, 使第一彩色滤光单元 128至少覆盖黑色矩阵 125的 一部分, 这样可以提高彩色滤光片的滤光品质。
继续参见图 12, 第一彩色滤光单元 128包括第一红色滤光单元 128a、 第一 绿色滤光单元 128b和第一蓝色滤光单元 128c; 第二彩色滤光单元 130包括第二 红色滤光单元 130a、 第二绿色滤光单元 130b和第二蓝色滤光单元 130c。 当然, 本发明针对的是 RGB色彩的滤光片组合而使用红色滤光单元、 绿色滤光单元及
蓝色滤光单元, 如果根据实际需要使用其它彩色滤光系, 如 CMYK彩色系等, 可以釆用其它的彩色滤光单元组合, 本实施例虽然对彩色滤光单元进行了举例 说明, 但是并不是对本发明权利范围的限制, 采用其它彩色滤光系形成的彩色 滤光片是对于本发明的简单替换, 落入本发明的保护范围。
在上述实施例中, 黑色矩阵 125可以是通过有机光阻材料或碳黑树脂制成, 但在其他实施例中并不限于由有机光阻材料或碳黑树脂制成。
在上述实施例中, 导电层 129 可以由氧化铟锡制成的透明导电层, 但在其 他实施例中并不限于由氧化铟锡制成制成。
请参阅图 13 , 为本发明彩色滤光片和薄膜晶体管阵列对组后的间隔区域示 意图, 106为彩色滤光片基板, 129为彩色滤光片导电层, 108为薄膜晶体管基 板, 109为薄膜晶体管第一层, 110为薄膜晶体管绝缘层, 111为薄膜晶体管第 二层, 112为薄膜晶体管通孔, 113为薄膜晶体管导电层, 114为导电颗粒。 本 发明间隔区部分的导电层 129 为不连续形态, 从而形成隔绝效果, 当彩色滤光 片和薄膜晶体管阵列在组装过程中, 间隔区即使存在导电颗粒时, 由于间隔区 的导电层 129 不连续, 就不会有共电位异常的情况发生, 从而可以防止彩色滤 光片和薄膜晶体管阵列组装异常短路, 进而提高产品质量。
以上所述仅为本发明的实施例, 并非因此限制本发明的专利范围, 凡是利 用本发明说明书及附图内容所作的等效结构或等效流程变换, 或直接或间接运 用在其他相关的技术领域, 均同理包括在本发明的专利保护范围内。
