Abstract:
1. An organic light emitting display comprising: a display region divided into a left part and a right part; a first data driver adapted to supply a data signal to odd numbered data lines corresponding to the left part; a second data driver adapted to supply the data signal to odd numbered data lines corresponding to the right part; a third data driver adapted to supply the data signal to even numbered data lines corresponding to the left part; a fourth data driver adapted to supply the data signal to even numbered data lines corresponding to the right part; and a controller comprising: a first line memory block adapted to store only odd numbered data to be supplied to the left and right parts in sequence in response to a writing signal and to output odd numbered data stored therein for the left and right parts at the same time in response to a reading signal, the first line memory block comprising a first memory adapted to store the odd numbered data for the left part and output directly to the first data driver, and a second memory adapted to store the odd numbered data for the right part and output directly to the second data driver; and a second line memory block adapted to store only even numbered data to be supplied to the left and right parts in sequence in response to the writing signal and to output even numbered data stored therein for the left and right parts at the same time in response to the reading signal, the second line memory block comprising a third memory adapted to store the even numbered data for the left part and output directly to the third data driver, and a fourth memory adapted to store the even numbered data for the right part and output directly to the fourth data driver; wherein the first line memory block comprises: first and third sub-memories in the first memory, adapted to store the odd numbered data for the left part in response to the writing signal and to supply the odd numbered data for the left part to the first data driver in response to the reading signal; and second and fourth sub-memories in the second memory, adapted to store the odd numbered data for the right part in response to a carry signal respectively supplied from the first memory and the third memory and to supply the odd numbered data for the right part to the second data driver in response to the reading signal.
