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: Methods and apparatus are provided for correcting an input error in an input apparatus capable of touch inputs of a first touch input scheme and a second touch input scheme. Upon detecting a touch input of the first touch input scheme, an activity corresponding to the detected touch input is executed and activity execution information corresponding to the activity is stored. The activity executed in accordance with the touch input of the first touch input scheme is cancelled, when a touch input of the second touch input scheme occurs before the touch input of the first touch input scheme is released or before a preset timer expires. The first touch input scheme and the second touch input scheme are different schemes.

Abstract: An apparatus and method are provided for controlling a coordinate measuring apparatus including a first touch panel that detects a contact of a portion of a human body and a contact of a coordinate indicating apparatus, and a second touch panel for detecting an electromagnetic signal from the coordinate indicating apparatus. The method includes determining a detection state of the coordinate indicating apparatus based on the electromagnetic signal detected by the second touch panel; and determining an activated area of the first touch panel based on the detection state of the coordinate indicating apparatus.

Abstract: A coordinate measurement system including a coordinate indicating apparatus and a coordinate measurement apparatus for determining a position of a contact object including the coordinate indicating apparatus. The coordinate measurement apparatus includes a channel electrode unit including one or more electrodes, wherein capacitance of each of the one or more electrodes or capacitance between the one or more electrodes is changed based on a change in the position of the contact object, and a controller for applying an electrical signal to the channel electrode unit or measuring a reception signal input to the channel electrode unit. The coordinate indicating apparatus includes a conductive tip for forming capacitance with the one or more electrodes of the channel electrode unit, and a resonant circuit unit for generating identification information of the coordinate indicating apparatus, wherein the resonant circuit unit is connected to the conductive tip.
