Abstract

An organic light emitting diode (OLED) display includes an illuminance sensing unit configured to sense an external illuminance, a brightness determination unit configured to determine a brightness of the OLED display according to an illuminance sensed by the illuminance sensing unit, a driving voltage determination unit configured to determine a driving voltage corresponding with a current saturation point of the OLED display, the driving voltage being determined based at least in part on a driving current and the brightness determined by the brightness determination unit, a voltage conversion unit configured to receive an input voltage, generate a first voltage higher than the input voltage, and generate a second voltage lower than the input voltage, and a display unit configured to receive the first and second voltages from the voltage conversion unit and display an image.

Description

technical field [0001] Embodiments relate to a display device capable of being driven with reduced power consumption and a driving method thereof. Background technique [0002] Recently, as digital technology continues to develop, various display devices have been developed. In particular, flat panel displays, such as liquid crystal displays (LCDs), plasma display panels (PDPs), and organic light emitting diode (OLEDs) displays, in which images are constituted by a plurality of pixels, have been developed. [0003] Among these flat panel displays, OLED displays having advantages such as high luminance, self-emission, wide viewing angle, and fast response speed have attracted special attention. [0004] Generally, an OLED display emits light in proportion to a driving current supplied from a driving transistor to an OLED of the OLED display. Accordingly, desired gray scales can be displayed on the OLED display by adjusting the amount of driving current or the duration of em...
