Organic light emitting diode (OLED) display and driving method thereof
Provided is an organic light emitting diode (OLED) display which includes a driving circuit and pixels arranged on pixel rows. In a (j−1)-th horizontal period, the driving circuit samples a threshold voltage of a driving Transistor (DT) of each pixel arranged on the (j−1)-th pixel row, and initializes a voltage of a gate electrode of a driving TFT of each pixel arranged on the j-th pixel row. In addition, in a j-th horizontal period, the driving circuit samples a threshold voltage of the driving TFT of each pixel arranged on the j-th pixel row.
