Triuorotoluene was used as a liquid suspending uidfor electrophoretic display (EPD).The dispersion stability, charge-ability, and response time of electrophoretic particles suspended intriuorotoluene were investigated.Hyperdispersant and assistanthyperdispersant (CH-11B) could provide satisfactory dispersionstability in triuorotoluene electrophoretic uid.The contrast ra-tio of simple electrophoretic display devices reached 2.95, 3.93,and 1.41, resp., and the response time was 305 ms/348 ms,512 ms/415 ms, and 140 ms/371 ms, resp.All of the devicesremained stable within 30 min after outage.The coating processusing the method of screen printing was studied with triuoro-toluene microcapsules as coating materials.The counts of meshand coating layer were key factors inuencing the performance ofcoating.Microcapsule type EPD prototypes showed outstandingdisplay results without coating defects.
