摘要
An Organic Light Emitting Diode (OLED) display device can include a display panel, a pixel circuit, and a data line and a power line connected in parallel and to the pixel circuit; a data driver for supplying a data voltage to the data line in display and sensing modes; and a sensing unit for supplying a high-potential voltage to the power line to drive the pixel circuit, cutting off supplying the high-potential voltage to the power line in a sensing duration of the sensing mode, sensing a voltage corresponding to a pixel current of the pixel circuit using the power line. A capacitor can be connected in parallel with the power line is charged according to the pixel current flowing through the power line, and the sensing unit senses the sensing voltage on the power line by sampling and holding the charged voltage in the capacitor.
