An OLED display apparatus and a driving method of the same are provided to prevent degradation of picture quality by compensating error values of a data voltage and driving current. A storage unit(121) stores temporarily previous data. A data compensation unit(122) compares present data with the previous data stored in the storage unit, outputs a compared value, and compensates the present data by using predetermined data compensation values corresponding to the compared value of data compensation values. The storage unit outputs the stored previous data when receiving the present data. The data compensation unit includes a subtracter(122-1) for comparing the present data with the previous data to produce the compared value, a compensation value output part(122-2) for outputting the predetermined data compensation value corresponding to the compared value of the data compensation values, and an adder(122-3) for adding the data compensation value to the present data to compensate the present data.
