    Abstract: An ElectroPhoretic Display (EPD) for changing a display is provided. An apparatus having the EPD applies a driving voltage with a periodic pulse to first color particles for a voltage applying period of the first color particles if a current temperature is below a predetermined temperature. The apparatus applies a driving voltage with a pulse that is kept at the same level as applied to second color particles for a voltage applying period of the second color particles. The first color particles have a higher mobility than the second color particles.

    Abstract: There is provided a metal etching mask fabrication method. Chrome is first sputtered on a silica layer and a photoresist, which is thicker than the chrome layer, is deposited on the chrome layer. The photoresist layer is patterned, a first nickel is sputtered on the photoresist pattern layer and onto a first portion of the chrome layer exposed by the patterning. A second nickel layer is formed on the portions of the first nickel layer in contact with the first portion of the chrome layer by electroplating. The photoresist pattern has side walls having acute angles to prevent contact between the first nickel layer on the photoresist and the second nickel layer on the first portion of the chrome layer. The photoresist pattern layer and the first nickel layer formed on the photoresist pattern layer are removed using a solvent, and the chrome layer is removed by dry etching in plasma using a gas.
