An organic light emitting display (OLED) device comprises: an estimated current calculation unit configured to estimate an increase estimated current value having at least one increased gray level and a decrease estimated current value having at least one decreased gray level with respect to current flowing cross an element; a current measurement unit configured to measure the current flowing across the element to generate a measured current value; and a luminance adjustment unit configured to compare the values supplied from the estimated current calculation unit and the current measurement unit and increase the luminance when the value inputted through the estimated current calculation unit is high and decrease the luminance when the value inputted through the estimated current calculation unit is low.
