Organic light emitting diode display and method of manufacturing the same
View Patent ↗An OLED display includes a first substrate and a second substrate adhered to the first substrate wherein a depressed receiving region and a coupling region formed around a receiving region are provided at an opposite surface to a surface facing the first substrate, a first optical film received in the depressed receiving region of the second substrate, a second optical film covering the first optical film and is disposed on the second substrate, and a coupling region adhesive layer is disposed between the second optical film and the coupling region of the second substrate.
1. An organic light emitting diode (OLED) display, comprising:
a first substrate;
a second substrate adhered to the first substrate wherein a depressed receiving region and a coupling region formed around the receiving region are provided at an opposite surface to a surface facing the first substrate;
a first optical film received in the depressed receiving region of the second substrate;
a second optical film covering the first optical film and disposed on the second substrate; and
a coupling region adhesive layer disposed between the second optical film and the coupling region of the second substrate.
2. The OLED display as claimed in claim 1 , wherein the first optical film is a phase delay film and the second optical film is a polarizer film.
3. The OLED display as claimed in claim 1 , wherein a depth of the depressed receiving region is substantially the same as a difference between a thickness of the first optical film and a thickness of the coupling region adhesive layer.
4. The OLED display as claimed in claim 1 , further comprising a receiving region adhesive layer disposed between the second substrate and the first optical film in the depressed receiving region.
5. The OLED display as claimed in claim 4 , wherein a depth of the depressed receiving region is substantially the same as the difference between a sum of the thickness of the first optical film and a thickness of the receiving region adhesive layer, and the thickness of the coupling region adhesive layer.
6. The OLED display as claimed in claim 1 , further comprising an inter-film adhesive layer disposed between the first optical film and the second optical film.
7. The OLED display as claimed in claim 6 , wherein a depth of the depressed receiving region is substantially the same as the thickness of a member received in the depressed receiving region.
8. The OLED display as claimed in claim 1 , wherein the depressed receiving region is an etched region.
9. The OLED display as claimed in claim 1 , wherein the first substrate includes an OLED.
