極化顆粒串式顯示介質之材料與封裝

Abstract

本論文提出了一種新的方法製作電子紙，稱為極化顆粒串電子紙。有別於市面上已有的電子紙顯示技術，我們能操控帶電或是不帶電的粒子，讓粒子在溶液中排列，藉此改變溶液之穿透率，達到明暗態之產生；且當不同種類、不同顏色之粒子在同一像素內分別驅動，即可實現全彩化的概念。本論文的研究將從粒子極化基礎現象開始探討並使用雷射印表機色粉與矽油製作油相顯示介質以及聚苯乙烯球與水溶液製作水相顯示介質之應用。而朝著提升顯示面積以及解析度為目的，我們從單一像素的製作方法開始到使用被動式驅動方法驅動具24x48解析度顆粒串介質電子紙的設計概念，以及利用厚度50μm的乾式光阻膜來優化元件製程與使用親疏水性質封裝24x48解析度之電子紙。

This thesis introduces a method to achieve an electronic paper by polarized particle chains. Different from other electronic paper techniques, the transmittance of a particle solution is modulated to provide dark and bright states by manipulating the suspended neutral or charged particles. Color electronic papers would be obtainable by individually driving of particles with different colors in a single pixel. In this thesis, basic studies of the particle polarization is studied by polystyrene beads dispersed in water and toners in silicone oil. From single pixel and direct driving scheme, a 24x48 pixel panel is fabricated, assembled, packaged, and passively driven. A 50-μm-thick dry photoresist film is used to optimize the device fabrication. In addition, packaging is facilitated by hydrophilic surface treatments.
