%X The driving properties of a particle-insertion method that filters non-moving particles are analyzed, by measuringits optical and electrical properties. An area that is occupied by the moved particles is proposed, as a desirableevaluation method for a reflective display. To compare the driving property of the particle-moving method withthat of the reported simple particle-loading method, two panels are fabricated, according to the different particleinsertionmethods, in the same panel condition, of which the width of ribs is 30 ¦Ìm, the cell size is 220 ¦Ìm ¡Á 220 ¦Ìm,the cell gap is 116-120 ¦Ìm, the q/m value of the black particles is +1.8 ¦ÌC/g and that for the white particles is -4.3 ¦ÌC/g. The particle-moving method has a filtering effect which excludes the non-moving particles, inserting only movableparticles into the respective cell, so that a panel fabricated by the particle-moving method can drive most of theparticles in a cell. Also, most of the particles move at the threshold voltage of 40 V, with enhanced reflectivity. Thedriving property is also verified by measurement of the occupation rate of the moved particles.
