【摘要】：薄膜晶体管行液晶显示(TFT-LCD)面板制造行业中,取向膜涂布方式主要有2种:一种为传统印刷方式辊式涂布法,另一种为新型印刷方式喷墨印刷法。本文通过对这2种印刷方式的比较,着重介绍了新型喷墨印刷法容易产生的三大主要不良(直线形不良、印刷头宽线形不良以及云状灰度不良)及产生原因。在对三大不良产生的原因进行详细的实验测试、数据分析和理论研究工作下,通过工艺调整并结合设备科学管控,最终使不良发生率大幅下降,极大地提高了产品的品质,并为今后新产品的开发及相关理论的研究提供了很好的基础。
[Abstract]:In the manufacturing industry of thin film transistor row liquid crystal display (TFT-LCD) panel, there are two kinds of oriented film coating methods: one is the traditional printing method, the other is the new printing method of inkjet printing. Based on the comparison of the two printing methods, this paper mainly introduces the three main disadvantages of the new inkjet printing method (poor linear shape, poor width and alignment of the printing head and poor cloud gray level) and its causes. Under the detailed experimental test, data analysis and theoretical research of the three bad causes, through process adjustment and scientific management and control of equipment, the incidence of bad products is greatly reduced, which greatly improves the quality of the products, and provides a good basis for the development of new products and the research of related theories in the future.
