Abstract
We propose a new particle-insertion method for a reflective display based on the structure
of a quick response-liquid powder display (QR-LPD). To compare this method with the reported
simple loading method, two panels are fabricated in the same panel condition of which the width of
ribs is 30 µm, the cell size is 220 µm × 220 µm, the cell gap is 116–120
µm, the <i>q</i>/m value of the black particles is +1.8 µC/g and that for the white
particles is 4.3 C/g. This method excludes the non-moving particles, inserting only mobile
particles into a substrate by using electric fields so that a panel fabricated by the
particle-moving method can drive most of the particles in a cell. Also, most of the particles move
at the threshold voltage of 40 V with enhanced reflectivity.
