摘要

为了实现TFT LCD产品的窄边框化，分析了不同因素的影响程度，加强了对取向膜印刷精度的管控。同时对涉及该过程相关因素进行研究分析。对取向膜印刷精度相关的APR版收缩率、APR版固定夹具、APR版边缘角度、APR版边缘开口率进行优化测试，找到了可以控制取向膜印刷精度的方法。实验结果表明：通过对APR版收缩率进行优化后，可以明显改善PI EM的过程能力（Ppk 0.661.31）；通过对APR版的夹具固定方式和挂版方式进行改善，边缘波动可以明显改善（边缘与中间Panel EM波动范围在477138 m）；通过对APR版边缘300 m的角度变更（7545），边缘波动改善明显（6343 m）；通过对APR版边缘300 m的开口率优化（30%35%），降低载液量，边缘波动得到进一步优化（4322 m）。该方法可以满足取向膜印刷精度的稳定管控、适应窄边框等要求。

Abstract

In order to achieve a narrow border on TFT LCD product

the impact of different factors was analysed. The alignment film printing precision control was strengthened

meanwhile factors involved in the process were researched and analysed. The accuracy of the alignment layer printed version shrinkage associated change of Contraction rate of APR

APR Jig

Edge angle and edge Aperture Opening Ratio were optimized.The method to control PI EM was found. Experimental results indicate that the process capability of PI EM was improved by offset and Shrinkage Optimization(Ppk 0.661.31).Edge fluctuations were significantly improved by the way of change of clamp fixation and hanging version way(fluctuations in the amount of edge: 477138 m).The edge fluctuations improved significantly by APR edition edge angle changes (7545@300 m from the edge) (fluctuations in the amount of edge: 6343 m).The edge fluctuation was further optimized by reducing the amount of carrier liquid (APR plate edge through the opening ratio optimization 300 m

(30%35%)(fluctuations in the amount of edge: 4322 m). It can satisfy the requirements of alignment film printing precision stability control and narrow frame.
