基于相变操控的电润湿显示油墨填充与封装工艺研究

A novel oil-filling and coupling method based on phase manipulation for electrofluidic displays

  • 摘要: 彩色油墨的填充与封装工艺是电润湿显示制造技术的核心,如何提高填充均匀性和制程效率仍然是电润湿显示技术量产的关键挑战之一。本文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。本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: Color oil filling and coupling are critical parts of electrofluidic display fabrication process. How to improve the uniformity and efficiency of the filling process is still a critical challenge for electrofluidic displays technology. A novel oil filling and coupling approach based on phase manipulation is proposed in this paper, which allows the filling conducting in the atmospheric environment, while carrying out the coupling in the liquid environment with the oil in frozen condition. The complexity caused by oil/water/solid interface manipulation in traditional filling method is avoided in this proposed approach, which improves the stability and compatibility of the filling process. The oil thickness analysis indicates the phased manipulation filling method giving a better controllability compared to traditional self-assembly method. The electro-optical response performance of the display device using phase manipulating method is comparable with that using normal process. This work provides a powerful method for overcoming the filling and coupling bottleneck in electrofluidic display manufacturing, and will accelerate the commercialization of electrofluidic display technology.
