ORGANIC LIGHT EMITTING DIODE (OLED) DISPLAY AND DRIVING METHOD THEREOF

摘要

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.

主权项

1. An organic light emitting diode (OLED) display comprising:
a plurality of pixels arranged on n number of pixel rows including a j-th pixel row, wherein n and j are integers and j is equal to or smaller than n; and a driving circuit comprising a gate driver that supplies a scan signal to each pixel row and a data driver that supplies data voltages to pixels arranged on a pixel row supplied with the scan signal, wherein, in a (j−1)-th horizontal period during which the scan signal is supplied to a (j−1)-th pixel row, the driving circuit samples a threshold voltage of a driving transistor in each pixel arranged on the (j−1)-th pixel row, and initializes a voltage of a gate electrode of a driving transistor in each pixel arranged on the j-th pixel row.
