【摘要】：文章提出一种基于相变操控的电润湿显示油墨创新填充和封装方法,即在空气环境中完成油墨液相填充,经低温凝固后投入液体环境完成封装.该方法有效规避了在传统液下环境中填充涉及的油/水/固三相界面操控的复杂性,提高了填充工艺的兼容性和稳定性.对油墨厚度的分析结果表明,基于相变操控填充油墨厚度与像素墙高度的相关性更好,较传统自组装填充具有更好的膜厚控制性.相变操控填充电润湿显示器件的光电响应处于合理水平.该研究有效解决了电润湿显示油墨填充的技术瓶颈,对推进电润湿显示技术的应用具有重要意义.
[Abstract]:In this paper, an innovative filling and packaging method of electric wetting display ink based on phase change manipulation is proposed, that is, the liquid phase filling of ink is completed in the air environment. After solidification at low temperature, the encapsulation is completed in liquid environment. This method effectively avoids the complexity of the control of oil / water / solid three-phase interface filled in traditional liquid environment. The results of ink thickness analysis show that the correlation between ink thickness and pixel wall height is better based on phase change control. Compared with the traditional self-assembly packing, the film thickness control is better. The photoelectric response of the phase-change control and filling electrical wetting display device is at a reasonable level. This research effectively solves the technical bottleneck of electrical wetting display ink filling. It is of great significance to promote the application of electric wetting display technology.
