Abstract

An organic light emitting diode (OLED) display device having a built-in touch panel and a manufacturing method thereof in which an OLED array and a touch array are formed on a flexible substrate and thus the OLED display device has flexibility, and a flexible printed circuit board for driving the touch array is integrally formed with a printed circuit board for driving the OLED array and thus manufacturing costs are reduced are disclosed. The OLED display device includes an OLED array formed on a lower flexible substrate, a touch array formed on an upper flexible substrate, and an adhesive layer adhering the upper flexible substrate to the lower flexible substrate such that the touch array and the OLED array face each other.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An organic light emitting diode (OLED) display device comprising:
 an OLED array on a lower flexible substrate;   a touch array on an upper flexible substrate; and   an adhesive layer adhering the upper flexible substrate to the lower flexible substrate such that the touch array and the OLED array face each other.   
     
     
         2 . The OLED display device according to  claim 1 , wherein the touch array comprises X and Y electrodes crossing each other, a pad part, and a routing line connecting the pad part to the X and Y electrodes,
 wherein the pad part is connected to the OLED array via an anisotropic conductive paste.   
     
     
         3 . The OLED display device according to  claim 2 , wherein the anisotropic conductive paste has a first end connected to the pad part and a second end on the lower flexible substrate and connected to a flexible printed circuit board for driving the touch array. 
     
     
         4 . The OLED display device according to  claim 3 , wherein the flexible printed circuit board is integrally formed with a printed circuit board electrically connected to the OLED array to drive the OLED array.
