Abstract

An organic light emitting diode display device includes a substrate having an active area and a non-active area, a light emitting diode in the active area, a sealing layer over the light emitting diode, at least one lens pattern over the sealing layer, the at least one lens pattern having a convex shape, and a passivation layer in the active area and the non-active area, the passivation layer covering the at least one lens pattern and having a first open portion exposing a first pad area.

Claims (43)

1. An organic light emitting diode display device, comprising:

a substrate having an active area and a non-active area;

a light emitting diode disposed in the active area;

a sealing layer disposed over the light emitting diode;

at least one lens pattern disposed over the sealing layer and having a convex shape; and

a passivation layer disposed in the active area and the non-active area,

wherein the passivation layer covers the at least one lens pattern and has a first open portion exposing a first pad area.

2. The device of claim 1 , further comprising a first dam surrounding the first pad area and disposed on the substrate.

3. The device of claim 2 , further comprising a data driving part disposed in the first pad area.

4. The device of claim 3 , further comprising a second pad area disposed at a side of the first pad area.

5. The device of claim 4 , further comprising an external driving circuit connected to the second pad area,

wherein the passivation layer has a second open portion exposing the second pad area.

6. The device of claim 5 , further comprising a second dam surrounding the second pad area is disposed on the substrate.

7. The device of claim 1 , wherein the non-active area has a bending area that is disposed between the active area and the first pad area, and

wherein the passivation layer has a third open portion exposing a portion of the bending area.

8. The device of claim 7 , further comprising a third dam surrounding the portion of the bending area and disposed on the substrate.

9. The device of claim 1 , wherein the non-active area has a boundary area that is disposed between the first pad area and an end portion of the non-active area.

10. The device of claim 9 , further comprising a boundary dam surrounding the boundary area and disposed on the substrate,

wherein the passivation layer has a boundary open portion exposing the boundary area.

11. The device of claim 1 , wherein the passivation layer includes epoxy resin or acrylic resin having a hydroxy group (—OH) or a fluorine group (—F) added to a substituent group, or epoxy resin or acrylic resin having nano hollow silica.

12. The device of claim 1 , wherein the passivation layer has a refractive index smaller than a refractive index of the at least one lens pattern.

13. The device of claim 1 , wherein the light emitting diode has an emission area corresponding to the at least one lens pattern.

14. The device of claim 1 , further comprising a touch pattern of a mesh shape having an opening disposed over the sealing layer,

wherein the at least one lens pattern is disposed to correspond to the opening of the touch pattern.

15. An organic light emitting diode display device, comprising:

a substrate having an active area and a non-active area;

a light emitting diode disposed in the active area;

a sealing layer disposed over the light emitting diode;

at least one lens pattern disposed over the sealing layer and having a convex shape; and

a passivation layer covering the at least one lens pattern

a first dam surrounding a first pad area and disposed on the substrate;

a data driving part disposed in the first pad area;

a second pad area disposed at a side of the first pad area;

an external driving circuit connected to the second pad area; and

a second dam surrounding the second pad area disposed on the substrate,

wherein the passivation layer has a first open portion exposing the first pad area and a second open portion exposing the second pad area.

16. The device of claim 15 , wherein the non-active area has a bending area that is disposed between the active area and the first pad area, and

wherein the passivation layer has a third open portion exposing a portion of the bending area.

17. The device of claim 16 , further comprising a third dam surrounding the portion of the bending area.

18. The device of claim 17 , further comprising a boundary dam surrounding a boundary area,

wherein the passivation layer has a boundary open portion exposing the boundary area.

19. The device of claim 15 , wherein the passivation layer includes epoxy resin or acrylic resin having a hydroxy group (—OH) or a fluorine group (—F) added to a substituent group, or epoxy resin or acrylic resin having nano hollow silica.

20. The device of claim 19 , wherein the passivation layer has a refractive index smaller than a refractive index of the at least one lens pattern.
