Description

配向膜涂布方法和配向膜涂布装置
【技术领域】
本发明涉及液晶显示器技术领域， 特别涉及液晶显示器中用于彩色滤光片 的配向膜涂布方法和配向膜涂布装置。
【背景技术】
高世代液晶面板的配向膜涂布技术釆用喷墨的方式， 以高速且高密度的配 向膜液滴滴落在薄膜晶体管（ Thin Film Transistor, TFT )基板或彩色滤光片（ Color filter, CF )基板表面上， 通过配向膜液滴表面张力的扩散作用使得涂布的配向膜 形成平整膜面。 喷墨涂布效果受 TFT ITO中的过孔和彩色滤光片基板中滤光片 厚度断差的影响， 导致同样大小的配向膜液滴形成的膜面效果不一。
请一并参阅图 1和图 2, 该彩色滤光片基板 100包括玻璃基板 110, 该玻璃 基板 110上设有黑色矩阵 120及行列排布的多组面积相等且厚度不等的长方体 R、 G、 B三原色滤光片 130, 图中仅示出一组为例。
请参阅图 3 , 现有技术中彩色滤光片基板 100涂布配向膜时， 通过包括多个 喷嘴 150的喷头 140以图示中箭头的方向平行移动， 由于该 R、 G、 B三原色滤 光片 130具有厚度段差， 故涂布效果会受该 R、 G、 B三原色滤光片 130的厚度 段差的影响， 即当配向膜液滴滴落在具有厚度差的两滤光片 130之间时， 会导 致该配向膜液滴无法平坦地扩散到该两滤光片 130表面，从而易导致滤光片 130 表面的配向膜膜厚不均勾平整。
目前业界或釆用大液滴的方式， 或釆用喷头 140移动速度降低的方式， 或 以缩减喷嘴 150 间距的方式集中液滴的密度来对付， 但因配向膜滴液的粘度关 系而仍有扩散不均的现象产生， 另外也影响了工时。
