摘要:
An organic light emitting display device includes an organic light emitting display panel, and a driver that drives the organic light emitting display panel. The driver applies a first power voltage and a second power voltage to the organic light emitting display panel, the first power voltage is lower than the second power voltage during a first period, and the first power voltage is higher than the second power voltage during a second period.

An organic light emitting diode display includes at least one pixel circuit, a scanning drive unit connected to the pixel circuit through a scan line and generating a selection signal to be applied to the pixel circuit, and a data drive unit connected to the pixel circuit through a data line and applying a data voltage to the pixel circuit. The data drive unit includes a first line to which the data voltage is applied and a demultiplexer connected between the first line and a first end of the data line, the demultiplexer time-divisionally applying the data voltage applied to the first line to the data line according to a demultiplexing signal. In one horizontal cycle, at least a portion of a period in which the demultiplexing signal is applied and at least a portion of a period in which the selection signal is applied overlap each other.

The present invention relates to mobile communication devices and a method of controlling the same. The mobile communication device includes a plurality of keys for entering different commands in first and second operating modes, memory for storing key mapping information in which commands corresponding to respective inputs of the plurality of keys are mapped every operating modes, and a mode switch detection unit for determining whether to switch an operating mode from the first operating mode to the second operating mode. When the operating mode is switched, a controller controls some of the plurality of keys to switch to key mapping information used in the second operating mode and the remaining keys to maintain key mapping information used in the first operating mode, based on the key mapping information.

A method and an apparatus for providing a multi-tasking interface of a device such as a portable communication device are provided. The method for providing a multi-tasking interface of a terminal preferably includes: receiving background switch input switching an display of an application being executed in a foreground to a background; switching the display of the application to the background when the background switch input is received; displaying a background control interface; and switching the display of the application to the foreground when preset switch input is received through the background control interface.
