摘要： A method of driving an organic light emitting diode (OLED) display device that displays grayscales in a time-division manner and can prevent the occurrence of false contours and flickers at an interface between neighboring grayscales when displaying sequential images, such as moving images, at a high speed. The method is an interlaced scanning method in which a single frame is divided into an odd-numbered field and an even-numbered field that are sequentially driven, and includes dividing each of the odd-numbered field and the even-numbered field into x sub-frame groups; dividing each of a plurality of sub-frames corresponding to bits of driving data into y divided sub-frame portions; and disposing the y divided sub-frame portions in different ones of the x sub-frame groups.

摘要： An organic light emitting diode display device includes a display unit including a plurality of pixels; a data driver applying data voltage to the pixels; and a power supplier including a first power source providing high-level voltage to the anode electrode of organic light emitting diodes and a second power source providing low-level voltage to the cathode electrode of the organic light emitting diodes included in the pixels, in which the power supplier provides the second power source in a sink method at positive voltage, when the threshold voltage of a driving transistor for driving the organic light emitting diodes shifts to a negative. When gate-source voltage of a driving transistor shifts to negative threshold voltage, it is possible to apply the data voltage at positive voltage and to simplify a driving IC, thereby ensuring wide use, by applying voltage of a second power source ELVSS at positive voltage.
