Light emitting panel and a light source for reducing deterioration of pixel
In light emitting panel, the light emitting panel includes a substrate, a pixel part and a protection part. The pixel part has more than or equal to two unit parts separated from each other. The protection has a concave part marking off neighboring unit parts.
1. A light emitting panel comprising:
a substrate;
pixel parts located apart from each other, formed on the substrate;
a protection part comprising an indented part, wherein both ends of the protection part are coupled with the substrate on which the pixel parts are formed by sealants so that a space is for med between the pixel parts and the protection part, and the indented part is concaved corresponding to areas between the pixel parts toward the substrate; and
a heat transmission part located between the pixel parts, and having a first surface directly contacted with the protection part at a location opposing to the indented part of the protection part and a second surface directly contacted with the substrate.
2. The light emitting panel of claim 1 , wherein the indented part is separated from the substrate.
3. The light emitting panel of claim 1 , wherein the heat transmission part is in contact with the indented part of the protection part.
4. The light emitting panel of claim 1 , wherein the heat transmission comprises a thermal pad.
5. The light emitting panel of claim 4 , wherein the heat transmission part comprises a getter.
6. The light emitting panel of claim 1 , wherein the protection part comprises either a metal, a glass or a plastic.
7. The light emitting panel of claim 1 , wherein the pixel section emits a white color.
8. The light emitting panel of claim 7 , wherein the pixel section comprises a sub-pixel.
9. The light emitting panel of claim 8 , the sub-pixel comprises an emission part comprising an organic material disposed between two electrodes.
10. A light source comprising:
a substrate;
pixel parts divided from each other, formed on the substrate;
a protection part comprising an indented part, wherein both ends of the protection part are coupled with the substrate on which the pixel parts are formed by sealants so that a space is for med between the pixel parts and the protection part, and the indented part is concaved corresponding to areas between the pixel parts toward the substrate; and
a heat transmission part located between the pixel parts, and having a first surface directly contacted with the protection part at a location opposing to the indented part of the protection part and a second surface directly contacted with the substrate.
11. The light source of claim 10 , wherein the indented part is separated from the substrate.
12. The light source of claim 10 , wherein the heat transmission part is in contact with the indented part of the protection part.
13. The light source of claim 10 , wherein the heat transmission comprises a thermal pad.
14. The light source of claim 13 , wherein the heat transmission part comprises a getter.
15. The light source of claim 10 , wherein the protection part comprises either a metal, a glass or a plastic.
16. The light source of claim 10 , wherein the pixel section emits a white color.
17. The light source of claim 16 , wherein the pixel section comprises a sub-pixel.
18. The light source of claim 17 , the sub-pixel comprises an emission part comprising an organic material disposed between two electrodes.
19. The light source of claim 16 , the light source is used for a light apparatus or a back light unit.
