电流体喷印高分辨率量子点颜色转换层研究
Research on high-resolution quantum dot color conversion layers fabricated by electrohydrodynamic printing
摘要
Abstract
High resolution pixelation is crucial for realizing photoluminescent quantum dot color conversion layers for augmented reality(AR)and virtual reality(VR)displays.Electrohydrodynamic(EHD)printing offers advantages such as high precision and broad ink compatibility;however,the complexity of process parameters limits its stable ap-plication.In this study,a commercial quantum dot color conversion ink was employed as the printing material.First,the mechanism of electric-field-induced Taylor cone formation and stable jet generation was elucidated.The effects of key parameters,including pulse amplitude voltage,duty cycle,and frequency,on the droplet printing behavior of quantum dot ink were systematically investigated.After process optimization,highly uniform dot arrays with a diam-eter of approximately 10 µm and a pixel density of 1 000 ppi,as well as continuous lines with a linewidth of 26 µm,were successfully achieved.Furthermore,in combination with photolithographically fabricated barrier banks,precise filling and pixelated arrangement of red and green quantum dots were realized within 80 µm pixel wells,effectively suppressing optical crosstalk.This study verifies the feasibility of fabricating color conversion layers for high resolu-tion full-color display devices.关键词
