摘要
An OLED display device which can sense a current of each pixel at high speed by a simple structure in order to compensate for luminance non-uniformity and a pixel current sensing method thereof are discussed. The OLED display device includes a display panel including pixels, each including a light emitting element and a pixel circuit for independently driving the light emitting element, a data driver for driving a data line connected to the pixel circuit using a data voltage, floating one of the data line, a reference line for supplying a reference voltage to the pixel circuit, and a power line for supplying a power to the pixel circuit to use the floated line as a current sensing line, sensing a voltage corresponding to a pixel current of the pixel circuit flowing to the current sensing line, and outputting the sensing voltage, in a sensing mode.
