A panel manufacturing process for multi‐color electrowetting display (EWD) by using ink‐jet printing (IJP) technique had been developed. To achieve multi‐color, two strategies were used, i.e., by using black oil with color filter and by using various colored oils without adopting color filter. for colored oils, various dyes had been used to blend with alkane solution. Then, the jetting behavior of different colored oil for IJP was investigated. Here, a 6‐inch multi‐color EWD prototype with black oil and color filter was successfully fabricated, and a dual color EWD panel with black and red oils had also been first evaluated.

The synergy of through-thickness gradation in the orientation of the molecular director and the extent of polymerization is shown to offer a framework for controlling shape selection in integral polymer films.
