Abstract
PURPOSE: To make possible the selection of display colors by changing the driving voltage polarity of the display device which makes use of electrophoresis.
CONSTITUTION: If the polarity of the voltage to be applied to the electrodes of a display plate 8 which makes use of electrophoresis with the rutile type titanium dioxide or other coated an epoxy resin as dispersing pigment fine particles and tetrafluoroethane dibromide colored to a black color by oil black dyes as dispersant is changed over by a power source polarity changeover switch 5, one of the colors by the dispersing particles or dispersant of the display plate 8 to be determined by the voltage polarity having been applied immediate before through segment driving signals T1, T2... changes to the other color. Hence, those things such as discriminated displaying of positive and negative numbers by colors through changing of applied voltage polarity for the same number may be readily accomplished.
