Abstract
We propose a color realization method of a reflective
display based on quick response-liquid powder display (QR-LPD). We use the
particle-moving method in order to address the color particles cyan, magenta,
yellow, and black (CMYK) into their respective cells. We fabricated a color
addressed reflective display panel using indium–tin–oxide (ITO)
glass with a rib width of 15 $\mu$m, a cell size of 300 $\mu$m$\times$300 $\mu$m, an average particle diameter of 8 $\mu$m, and a particle charge to mass
ratio (q/m) from ${+}{\hbox{8.5}}\
\mu$C/g to ${-}{\hbox{4}}\
\mu$C/g. Most particles are inserted into their cells on the
upper substrate, with non-movable particles removed in a previous step. The
fabricated color panel shows a well-addressed CMYK array in microscopic photographs.
An additional color display is fabricated using line-by-line addressing in
order to facilitate the addressing process.
