Summary:An objective of the present invention is to provide an organic light emitting display device capable of measuring the deterioration degree of organic light emitting diodes provided in a non-display area of one organic light emitting display panel using a constant current and compensating data voltages supplied to organic light emitting diodes provided in a display area of the organic light emitting display panel according to a measurement value. The organic light emitting display device comprises: an organic light emitting display panel; a gate driver; a data driver; a high voltage supply unit; a switching unit; a sensing unit; and a control unit. 본 발명의 목적은, 하나의 유기발광 표시패널의 비표시영역에 구비된 유기발광 다이오드들의 열화정도들을 정전류를 이용하여 측정하며, 측정값에 따라 상기 유기발광 표시패널의 표시영역에 구비된 유기발광 다이오드들로 공급되는 데이터 전압들을 보정할 수 있는, 유기발광 표시장치를 제공하는 것이다.
