Display device having touch screen
A display device comprises: a pixel array substrate comprising first pads; a touch screen substrate comprising second pads; an adhesive film that attaches the pixel array substrate and the touch screen substrate; and a conductive sealant that electrically connects the first pads and the second pads between the pixel array substrate and the touch screen substrate. The adhesive film comprises: an opening with the conductive sealant applied thereto; and an extension portion that surrounds the opening.
1. A display device comprising:
a pixel array substrate comprising an active area on which an input image is displayed and first pads outside the active area;
a touch screen substrate comprising second pads;
a non-conductive adhesive film that is extended from the active area to outside the active area and attaches the pixel array substrate and the touch screen substrate; the non-conductive adhesive film having an opening in a portion thereof outside the active area exposing opposing first and second pads, and, an extension portion of the non-conductive adhesive film surrounds at least a portion of the opening; and
a conductive sealant disposed in the opening electrically connects the first pads and the second pads.
2. The display device of claim 1 , wherein the extension portion extends along left and right sides of the adhesive film and defines the opening.
3. The display device of claim 2 , wherein one or more of the first and second extension portions are connected to the adhesive film.
4. The display device of claim 3 , wherein the pixel array substrate comprises thin film transistors and organic light emitting diodes.
5. The display device of claim 2 , wherein one or more of the first and second extension portions are disconnected from the adhesive film.
6. The display device of claim 5 , wherein the pixel array substrate comprises thin film transistors and organic light emitting diodes.
7. The display device of claim 1 , wherein the extension portion extends along a top or a bottom side of the adhesive film and defines one edge of the opening.
8. The display device of claim 1 , wherein the extension portion comprises:
a first extension portion that extends along the left and right sides of the adhesive film and defines the opening; and
a second extension portion that extends along the top or bottom side of the adhesive film and defines the other edge of the opening.
