Abstract
A displaying method includes forming nuclear crystals of a metal on an electrode, and depositing a metal on a surface of the nuclear crystals from a solution including a metallic ion, so as to form particles having a particle diameter corresponding to a display color.
Claims10
A displaying method comprising:
- forming nuclear crystals of a metal on an electrode;
- depositing the metal on a surface of the nuclear crystals from a solution including a metallic ion, so as to form particles having a particle diameter corresponding to a display color,
- applying a first applied voltage between a first electrode as the electrode and a second electrode disposed to face the first electrode, so as to form the nuclear crystals from the solution,
- applying a second applied voltage between the first electrode and the second electrode, so as to deposit the metal from the solution,
- controlling the number of the nuclear crystals by controlling an application time of the first applied voltage, and
- controlling the particle diameter of the particles by controlling an application time of the second applied voltage.
