OLED display device and method for fabricating the same
View Patent ↗An OLED display device is provided, which includes a first substrate, an OLED layer, a first blocking material, a second substrate, and a second blocking material. The first substrate has a first lateral surface, and the second substrate has a second lateral surface. The OLED layer is disposed between the first and second substrates. The first blocking material is disposed at a peripheral region of the OLED layer to connect the first and second substrates. The second blocking material is disposed on the first and second lateral surface and covers a gap between the first and second lateral surfaces.
1. An OLED display device, comprising:
a first substrate, having a first lateral surface;
a second substrate, having a second lateral surface;
an OLED layer, disposed between the first substrate and the second substrate;
a first blocking material, disposed at a peripheral region of the OLED layer to connect the first substrate with the second substrate, wherein the first blocking material comprises a UV glue; and
a second blocking material, disposed on the first and the second lateral surfaces and covering a gap formed between the first substrate and the second substrate, wherein the second blocking material comprises a glass frit.
2. The OLED display device as claimed in claim 1 , wherein the first blocking material and the second blocking material are separated by a distance.
3. The OLED display device as claimed in claim 1 , wherein a thickness of the second blocking material is in a range from 1 μm to 5 mm.
4. The OLED display device as claimed in claim 1 , wherein the first substrate further has a first outer surface, and the second substrate further has a second outer surface, and a height of the second blocking material is less than a distance between the first outer surface and the second outer surface.
5. The OLED display device as claimed in claim 1 , wherein the color of the light emitted from the OLED layer is white.
6. The OLED display device as claimed in claim 1 , wherein the second substrate comprises a color filter.
7. A method for fabricating an OLED display device, comprising:
providing a first substrate, wherein an OLED layer is deposited on the first substrate;
applying a first blocking material at a peripheral region of the OLED layer;
providing a second substrate and placing the second substrate on the first substrate;
curing the first blocking material by a UV light, to combine the first substrate and the second substrate together;
applying a second blocking material on lateral sides of the first substrate and the second substrate; and
hardening the second blocking material by a laser.
8. The method for fabricating an OLED display device as claimed in claim 7 , prior to the step for applying the second blocking material, further comprising providing a low-moisture and low oxygen content processing environment so as to block moisture and oxygen in the atmosphere from the OLED layer.
