Abstract
Provided is a display unit capable of improving display performance. The display unit includes an electrophoretic particle disposed between a pair of electrodes for each pixel; and a voltage control circuit applying a voltage for each pixel, to move the electrophoretic particle. The voltage control circuit counts, for each pixel, a number of applications of a first voltage and a number of applications of a second voltage, the first voltage being applied to move the electrophoretic particle towards one of the electrodes, and the second voltage being applied to move the electrophoretic particle towards the other of the electrodes. Further, at an arbitrary timing following start of display, when the number of applications of the second voltage in part of pixels is smaller than that in other pixel, the voltage control circuit applies the second voltage to the pixel with the smaller number of applications, to bring this smaller number of applications closer to the number of applications in the other pixel.
