Zara Domain是高PPI TN型TFT-LCD制成中较为常见的一种不良
为了提高产品品质
急需改善Zara Domain。以3.97 in TN 产品(PPI 235)为例
Zara Domain发生率30%
对产品良率影响较大
文章结合生产情况对Zara Domain发生的原因进行理论分析和实验验证
得出改善Zara Domain的方法。首先
产品设计上可以通过增加平坦膜改善彩膜侧平坦度。其次
材料上可以选择高预倾角的配向膜以及低Pitch的液晶分子。最后工艺上优化摩擦强度和对盒后冷却工艺。实验结果表明:通过设计
材料
工艺三方面改善
最终生产过程中Zara Domain发生率<1%
提高了产品品质。
In order to improve the display quality of TN mode TFT-LCD product
Zara domain must be resolved which is a common defect. This paper talks about the 30% ratio Zara domain defect of 3.97 in TN mode TFT-LCD product with 235 PPI. Experiments show that the main factor influencing Zara domain is the matching of design and cell process & materials. First of all
we increase the thickness of OC to improve the CF side plainness. Second
we chose high pre-tilt angle PI ink & low pitch LC materials. Finally
the rubbing strength parameter & cooling ratio was adjusted. With suitable experiment conditions
good matching of design and cell process & materials
the display quality was largely improved
which Zara domain ratio is less than 1%.
