Organic light emitting display device

1 . An organic light emitting display device (OLED display), comprising:

first and second display panels arranged on a same surface;

a touch screen panel arranged integrally on the first and second display panels;

a touch screen panel controller adapted to drive the touch screen panel; and

a display controller adapted to control the first and second display panels, the display controller being further adapted to separate information displayed on the display panels into an image signal and a data signal corresponding to the image signal, the display controller being further adapted to supply the separated image signal and data signal to the first and second display panels, respectively.

2 . The OLED display of claim 1 , wherein each of the first and second display panels comprises:

a first substrate;

an image display unit including a plurality of thin film transistors and a light emitting element; and

an encapsulation substrate arranged on the first substrate, the encapsulation substrate being adapted to encapsulate the image display unit.

3 . The OLED display of claim 2 , wherein the touch screen panel is arranged integrally on the encapsulation substrate.

4 . The OLED display of claim 3 , wherein the touch screen panel comprises:

a transparent electrode arranged on one surface of the encapsulation substrate;

a metal electrode arranged at edges of the transparent electrode; and

a polarizer film arranged on the encapsulation substrate.

5 . The OLED display of claim 1 , wherein the touch screen panel is driven in a capacitive manner.
