FIG. 1 is a block diagram illustrating an organic light emitting display device including a multi-type thin film transistor according to an exemplary embodiment of the present disclosure.

Referring to FIG. 1, an organic light emitting display device 100 may include a display panel 10, a gate driver 11, a data driver 12, a multiplexer (MUX) 14, and a timing controller 13.

The timing controller 13 controls a display panel driving circuit including the gate driver 11 and the data driver 12 for writing data of an input image to pixels P of the display panel 10. When the display panel 10 further includes a touch sensing unit, the display panel driving circuit may further include a touch sensing driving unit.

In the display panel 10, a plurality of data lines DL and a plurality of scan lines SL cross each other, and a plurality of the pixels P are disposed in a matrix form. In addition, various lines such as an initialization voltage line, an emission control signal line, a high potential voltage line, and a low potential voltage line may be further disposed in the display panel 10, but the present disclosure is not limited thereto.

Each of the plurality of pixels P is a pixel for realizing one color, and the plurality of pixels P may include a red pixel, a green pixel, and a blue pixel. Also, in order to improve a luminance and lifespan of the display panel 10, the plurality of pixels P may further include a white pixel. The red pixel, the green pixel, and the blue pixel (and the white pixel) form one group, so that a desired color can be realized.
