Description
说 明 书 配向膜的边界获取方法及检测方法 技术领域
本发明涉及显示面板生产技术领域, 尤其涉及一种配向膜的边界获取方法 及检测方法。 背景技术
液晶显示装置 (LCD, Liquid Crystal Display)具有机身薄、 省电、 无辐射等 众多优点, 从而得到了广泛的应用。 现有市场上的液晶显示装置大部分为背光 型液晶显示装置, 其包括液晶显示面板及背光模组(backlight module)。液晶显 示面板的工作原理是在两片平行的玻璃基板当中放置液晶分子, 通过玻璃基板 通电电压来控制液晶分子改变方向, 将背光模组的光线折射出来产生画面。 配向膜用于施予液晶分子朝配向的方向排列, 使得液晶显示面板中的液晶 分子拥有一致的方向性, 或是定向排列。 当电场驱动液晶分子动作时, 全部或 局部的液晶分子需要有同步且一贯性的动作, 使得显示动作能快速且一致。 新一代的配向膜涂布技术是以喷墨 (Inkj et)印刷的方式, 使聚酰亚胺 (polyimide, PI)液覆盖在薄膜晶体管基板或是彩色滤光基板上, 再通过加热的 方式使 PI液里面的溶剂挥发, 从而形成一层固定膜厚的配向膜。 然而 PI液由 于液体所具有的流动性, 在固化的过程中会向外扩散, 在边缘 PI液会流到没 有涂布的地方,从而使得 PI液固化后在边缘处直线性不佳,易呈现波浪状 (Edge Wave)。现有改良 Edge Wave方法是以液滴的大小进行改善。以 DPI(dots per inch) 来做为一个衡量指标, DPI(dots per inch)越高, 达成的直线性就越高。 具体为 采用较小的 PI液滴并以较密集地排列达成较高的 DPI,然而在实际操作过程中 仍会出现 Edge Wave的现象。 另外, 因边缘干燥速度不同, 使得边缘会形成膜 厚不均的区域,称之为 Halo area或 Edge area。此 Halo area若位于显示区 (Active area), 则将于 25 %灰阶下的画面边缘会有明显偏白的现象。 因此, 在对配向膜 的检测以及切割精度的检测等后续制程中, 准确获取配向膜的边界尤其重要。 然而由于 PI液扩散后的边界亮度变化较多, 且玻璃基板上有大量的金属线路, 从而导致现有技术对配向膜的实际边界误抓率很高, 从而影响后续制程。

附图说明
图 1为本发明一实施例提供的一种配向膜的边界获取方法流程图。 图 2采用本发明提供的边界获取方法获取到的配向膜的边界的示意图, 其 中, 图 2a为抓取到的配向膜的边界示意图; 图 2b为第一次筛选后的边界示意 图; 图 2c为第二次筛选后的边界示意图。 具体实施方式
现在对本发明实施例进行详细的描述, 其示例表示在附图中, 其中, 相同 的标号始终表示相同部件。 下面通过参照附图对实施例进行描述以解释本发 明。
参阅图 1, 为本实施例提供的一种配向膜的边界获取方法流程图, 包括步 骤:
A、 对图像进行边缘处理, 抓取配向膜的边界;
B、 对抓取到的边界进行一次筛选, 排除为直线的边界;
C、 在一次筛选后的边界上进行二次筛选, 选取最外层的边界线作为配向
膜的实际边界。 具体地, 首先对含有配向膜的图像进行二值化处理: 设计一阈值, 用该阈 值将含有配向膜的图像分为两个部分, 即大于阈值的像素群和小于阈值的像素 群, 其中大于阈值的像素群的像素的灰度值被设为 255, 小于阈值的像素群的 像素的灰度值被设为 0。 当然, 在其他实施例中也可以相反, 即大于阈值的像 素群的像素的灰度值被设为 0, 小于阈值的像素群的像素的灰度值被设为 255。 在对图像进项二值化处理后, 选取图像内的任一像素, 与该像素周围的 8个像 素进行比较, 若该像素与周围的 8个像素的灰度值一致, 则去除该像素; 若该 像素与周围的 8个像素中的至少一个像素的灰度值不一致, 则保留该像素。 参阅图 2a, 为采用如上所述的方法抓取到的配向膜的边界, 由于配向膜是 覆盖在薄膜晶体管基板或是彩色滤光基板上, 薄膜晶体管基板或是彩色滤光基 板上均存在大量的金属线路, 而金属线路与配向膜之间的图像像素的灰度值不 一致, 因此抓取到的边界不仅包括配向膜的实际边界 110, 还包括金属线路的 边界 130,以及金属线路周围的由于配向膜的涂布不平整而形成的内在边界 120 或者 PI液涂布后在边界处扩散不均匀而形成的内在边界 120。 因此, 需要对抓 取到的边界做进一步的处理。 在抓取到配向膜的边界之后, 对抓取到的边界进行一次筛选, 具体为: 选 取一基准线, 并在抓取到的任一条边界线上随机选取多条线段; 计算该多条线 段与基准线之间的角度, 若角度均为一固定值, 则排除该条边界线; 若角度为 不固定的值, 则保留该边界线。 当然, 在其他实施例中, 也可以直接计算在抓 取到的任一条边界线上随机取得的多条线段之间的角度差, 若该角度差均为固 定值, 则排除该条边界线; 若该角度差为不固定的值, 则保留该条边界线。参 阅图 2b, 为一次筛选后的边界, 由于金属线路的边界一定为直线, 而由于 PI 液扩散后的边界轮廓为一扭扭曲曲的曲线, 因此在排除直线边界之后就可以把 误抓的金属线路的边界 130排除掉, 此时剩下的为配向膜的实际边界 110, 以 及位于实际边界 110内部的内部边界 120。 进一步地, 对一次筛选后的边界进行二次筛选, 其具体为: 建立坐标轴; 在 X值一定时, 保留竖直边界线上 Y值最大和最小的点, 删除其余竖直边界 线上的点; 在 Y值一定时, 保留水平边界线上 X值最大和最小的点, 删除其 余水平边界线上的点, 这样就筛除内部边界 120而保留最外层的边界了。 参阅
图 2c, 在二次筛选后, 选取的即为配向膜的实际边界 110。 基于同一发明构思, 本实施例还提供了一种配向膜的检测方法, 包括 采用如上所述的边界获取方法获取配向膜的实际边界;
在所述实际边界内对配向膜图像进行采集并处理;
将处理后的图像与数据库中的数据进行对比, 以判断是否有缺陷。 该检测方法通过提高配向膜实际边界获取的精度, 从而减小了检测难度, 提高了检测精度。
综上所述, 本发明提供配向膜的边界获取方法及检测方法, 通过对抓取后 的图像边界进行筛选, 不仅可以快速准确地获得配向膜的实际边界, 减小配向 膜边界的误抓率, 进而方便对配向膜的管控和防治; 而且该方法简单, 便于操 作。
