Zusammenfassung:The invention relates to an organic light emitting display device and a pixel sensing method of the same. A display device includes a display panel, a driving circuit, a sensing circuit, and a compensation circuit. The display panel includes a first pixel and a second pixel. The driving circuit provides a preset sensing voltage to the first pixel of the display panel, and provides a dummy voltageto the second pixel of the display panel. A first channel of a sensing circuit generates a first integrated voltage signal indicative of a magnitude of a first pixel current generated by the first pixel. A second channel of the sensing circuit generates a second integrated voltage signal indicative of a magnitude of a first dummy current generated by the second pixel. The compensation circuit determines a compensation amount from a difference between an output of the first and second channels of the sensing circuit, and compensates a display voltage of the first pixel by the compensation amount. 提供一种有机发光显示装置及其像素感测方法。一
