摘要： Disclosed are a waveguide member and a keypad assembly including the same. The waveguide member includes a waveguide for guiding light propagated inside, and at least one recess formed in a direction perpendicular to a direction of guidance of light coupled to the inside of the waveguide so that light guided by the waveguide is reflected to the waveguide. The keypad assembly includes a keypad having at least one key button and an elastic sheet fixing the key button, a waveguide member positioned beneath the keypad, the waveguide member having a waveguide for guiding light coupled to an inside and at least one recess for reflecting light guided by the waveguide to the waveguide, and a switch pad positioned beneath the waveguide member so as to establish an electric contact when the key button is pressed.

摘要： 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.
