Organic light emitting diode display
View Patent ↗An organic light emitting diode (OLED) display has an increased mechanical strength by improving the shape of a bezel combined to a panel assembly. The OLED display includes a panel assembly having a display area and a pad area, and a bezel accommodating the panel assembly. The bezel includes a bottom part on which the panel assembly is mounted, a side wall provided on a side of the bezel, and a hemming flange provided at another side of the bezel on which the side wall is not provided. The panel assembly is mounted in a manner that the pad area is turned towards the another side.
1. An organic light emitting diode (OLED) display comprising:
a panel assembly having a display area and a pad area; and
a bezel accommodating the panel assembly, the bezel comprising:
a side wall provided on a side of the bezel;
a hemming flange provided on another side of the bezel on which the side wall is not provided; and
a bottom part on which the panel assembly is mounted in a manner that the pad area is turned towards the another side.
2. The OLED display of claim 1 , further comprising:
a flexible printed circuit board coupled to the pad area and bending over to surround the hemming flange; and
a PCB electrically connected to the flexible printed circuit board.
3. The OLED display of claim 1 , wherein the panel assembly comprises a first substrate on which the pad area is formed, and an upper surface of the hemming flange is positioned to be higher than an upper surface of the first substrate.
4. The OLED display of claim 3 , wherein the hemming flange is formed to be bent at least twice toward an inside of the bezel.
5. The OLED display of claim 3 , wherein the hemming flange is positioned to be spaced apart from an edge of the first substrate.
6. The OLED display of claim 1 , wherein the hemming flange is formed to be bent at least three times toward an inside of the bezel.
7. The OLED display of claim 6 , wherein the hemming flange comprises a horizontal part that is substantially parallel to the bottom part.
8. The OLED display of claim 1 , wherein the hemming flange is formed by folding an edge portion of the bottom part toward an inside of the bezel.
9. The OLED display of claim 8 , wherein the hemming flange includes a horizontal part that is substantially parallel to the bottom part.
10. The OLED display of claim 1 , wherein the hemming flange is formed by folding an edge portion of the bottom part toward an outside of the bezel.
11. The OLED display of claim 10 , wherein the hemming flange includes a horizontal part that is substantially parallel to the bottom part.
12. The OLED display of claim 1 , wherein the bezel is made of metal.
13. The OLED display of claim 1 , further comprising:
an upper bezel that covers the pad area and is fixed to the panel assembly.
14. The OLED display of claim 13 , wherein the upper bezel is substantially the same size as the bottom part of the bezel, and includes an opening that exposes the display area.
15. The OLED display of claim 13 , wherein the upper bezel is fixed to the panel assembly by means of a double-sided adhesive tape.
