An apparatus and method for driving an organic light emitting display so as to minimize or prevent a raindrop phenomenon and an afterimage is provided. The apparatus and method determines the driving state of a pixel unit by using a vertical sync signal, and turns on or off the determined driving state of the pixel unit. The supply of the power voltage is sustained when the pixel unit is driven, and is turned off when the pixel unit is not driven. Accordingly, the apparatus and method can minimize or prevent a raindrop phenomenon and an afterimage by turning off the supply of the power voltage when the pixel unit is not driven.

A wireless communication terminal with an opening/closing function using a plurality of magnetic pole sensors and method therefor is provided. The invention activates or inactivates a display unit via a switch by sensing an opening/closing of a sub-body using the magnetic pole sensors, to thereby prevent a malfunctioning due to a magnetic pole caused by an external magnetic pole generator. The inventive wireless communication terminal comprises a first magnetic pole generator for generating a north (N) magnetic pole, a second magnetic pole generator for generating a south (S) magnetic pole, a first magnetic pole sensor for sensing the N magnetic pole from the first magnetic pole generator, a second magnetic pole sensor for sensing the S magnetic pole from the second magnetic pole generator, a controller for controlling an operation of a switch to activate or inactivate an output unit based on the sense result from the first and the second magnetic pole sensors, the switch performing a switching operation in response to a control signal from the controller, and the output unit activated or inactivated in accordance with the switching operation of the switch.
