Abstract: Disclosed are a mobile terminal and a control method thereof, which has a display unit for displaying a virtual keypad and texts input by the virtual keypad. The mobile terminal includes a display unit and a controller. The display unit has a first area in which a virtual keypad is displayed and a second area in which a character input by a touch applied to the virtual keypad is displayed, and displays a first cursor for guiding a position at which a character is to be input. When an editing mode is executed in the state in which the first cursor is displayed, the controller displays, in the second area, a second cursor different from the first cursor, and selectively activates any one of the first and second cursors.

Abstract: The present invention relates to a motor driving apparatus and a home appliance comprising the same. The motor driving apparatus according to an embodiment of the present invention comprises: an inverter which converts a direct current power source of a DC stage capacitor to an alternating current power source and outputs the converted alternating power source to a motor by a switching operation; a DC stage resistance device arranged between the DC stage capacitor and the inverter; and a control unit which controls the inverter on the basis of phase current sampled by means of the DC stage resistance device, wherein the control unit controls the frequency of voltage applied to the motor or the rotation frequency of the motor to be synchronized with the sampling frequency of the phase current sampled via the DC stage resistance device. Accordingly, it is possible to accurately calculate the phase current flowing through the motor by means of the DC stage resistance device.
