An organic light emitting display includes a display panel, which includes a plurality of pixels and displays an image, and a data driving circuit differently outputting a compensation voltage depending on a sensing value based on a driving current. Each of the plurality of pixels includes an organic light emitting diode, a driving thin film transistor (TFT) having a double gate structure including a main gate electrode and a sub-gate electrode, a switching TFT applying a data voltage determining the driving current to the main gate electrode of the driving TFT, and a compensation TFT applying the compensation voltage for compensating for a shift amount of a threshold voltage of the driving TFT to the sub-gate electrode of the driving TFT.

Organic light emitting display

An image display device is discussed. The image display device includes a display panel configured to selectively display a 2D image and a 3D image and a patterned retarder disposed line by line. The patterned retarder includes a first retarder transmitting only a left eye image of the 3D image from the display panel and a second retarder transmitting only a right eye image of the 3D image. Pixels disposed on the display panel alternately display the 3D image and a black image every one horizontal line in an interlace manner through a time division.
