Organic light emitting display device composed of multiple display panels
An organic light emitting display device that is used as a flat panel display and usable in a portable terminal that employs two separate display-panels. The organic light emitting display device has a first display panel and a second display panel provided on the same surface thereof; a touch screen panel (TSP) formed integrally on the first and second display panels; and one controller controlling the first and second display panels.
1 . An organic light emitting display device, comprising:
first and second display panels formed on the same surface thereof;
a touch screen panel formed integrally on the first and second display panels;
a touch screen panel controller driving the touch screen panel; and
a display controller controlling the first and second display panels.
2 . The organic light emitting display device according to claim 1 , wherein each of the first and second display panels comprises:
a first substrate formed with an image display unit including a plurality of thin film transistors and light emitting elements; and
an encapsulation substrate formed on the first substrate to encapsulate the image display unit.
3 . The organic light emitting display device according to claim 2 , wherein the touch screen panel is formed integrally on the encapsulation substrate.
4 . The organic light emitting display device according to claim 3 , wherein the touch screen panel comprises:
a transparent electrode formed on one surface of the encapsulation substrate;
a metal electrode formed on edges or respective sides of the transparent electrode; and
a polarizer film formed on the encapsulation substrate.
5 . The organic light emitting display device according to claim 1 , wherein the touch screen panel is driven in a capacitive manner.
6 . A display device, comprising:
a substrate;
a first display panel disposed on a surface of said substrate;
a second display panel disposed on said surface of said substrate adjacent to said first display; and
a touch screen panel formed integrally on both said first display panel and said second display panel,
wherein said first display panel and said second display panel each can display images simultaneously.
7 . The display device recited in claim 6 , further comprising:
a touch screen panel controller driving the touch screen panel; and
a display controller controlling the first and second display panels.
8 . The display device recited in claim 6 , wherein the substrate includes a plurality of thin film transistors and light emitting elements.
9 . The display device recited in claim 8 , wherein each of the first and second display panels further comprises:
an encapsulation substrate formed on the substrate to encapsulate the image display unit.
10 . The display device recited in claim 9 , wherein the touch screen panel is formed integrally on the encapsulation substrate.
11 . The display device recited in claim 10 , wherein the touch screen panel comprises:
a transparent electrode formed on one surface of the encapsulation substrate;
a metal electrode formed on edges or respective sides of the transparent electrode; and
a polarizer film formed on the encapsulation substrate.
12 . The display device recited in claim 6 , wherein the touch screen panel is driven in a capacitive manner.
13 . The display device recited in claim 6 , wherein the first display panel and the second display panel are organic light emitting displays.
