View Patent ↗An organic light emitting display device which prevents deterioration of an organic light emitting diode (OLED), the organic light emitting display device includes a first substrate including a display unit that includes at least one organic light emitting diode (OLED), a second substrate facing the first substrate and bonded to the first substrate, a sealant arranged surrounding the display unit and bonding the first substrate to the second substrate, a dam portion arranged between the display unit and the sealant and surrounding a periphery of the display unit and including a plurality of magnetic particles and a filling material arranged within an inner space of the dam portion and between the first and second substrates and including a plurality of magnetic particles.
1. An organic light emitting display device, comprising:
a first substrate including a display unit that includes at least one organic light emitting diode (OLED);
a second substrate facing the first substrate;
a sealant surrounding a periphery of the display unit and bonding the second substrate to the first substrate;
a dam portion arranged between the periphery of the display unit and the sealant and surrounding the periphery of the display unit and including a plurality of magnetic particles; and
a filling material arranged within an inner space defined by the dam portion and the first and second substrates, the filling material including a plurality of magnetic particles.
2. The device of claim 1 , wherein the sealant comprises frit.
3. The device of claim 2 , further comprising an inorganic insulating layer arranged on the first substrate and extending from the display unit to outside a periphery of the display unit, wherein the frit is arranged on the inorganic insulating layer.
4. The device of claim 1 , wherein facing and adjacent surfaces of the dam portion and the filling material repel each other due to the magnetic particles in the filling material and the magnetic particles in the dam portion.
5. The device of claim 1 , wherein the filling material further comprises a plurality of non-magnetic particles having no magnetism.
6. The device of claim 1 , wherein the dam portion is separated from the sealant by an interval.
7. The device of claim 1 , wherein the sealant comprises a plurality of magnetic particles.
8. The device of claim 7 , wherein facing and adjacent surfaces of the sealant and the dam portion repel each other due to the magnetic particles in the sealant and the magnetic particles in the dam portion.
9. An organic light emitting display device, comprising:
a first substrate including a display unit that includes at least one organic light emitting diode (OLED);
a second substrate facing the first substrate;
a sealant surrounding a periphery of the display unit and bonding the second substrate to the first substrate;
a first dam portion arranged on a surface of the first substrate facing the second substrate, the first dam portion being arranged between the display unit and the sealant and surrounding the periphery of the display unit, the first dam portion including a plurality of magnetic particles;
a second dam portion arranged on a surface of the second substrate correspondingly facing the first dam portion and including a plurality of magnetic particles; and
a filling material arranged within a space defined by the first and second dam portions and the first and second substrates, the filling material including a plurality of magnetic particles.
10. The device of claim 9 , wherein the sealant comprises frit.
11. The device of claim 10 , further comprising an inorganic insulating layer arranged on the first substrate and extending from the display unit to outside a periphery of the display unit, wherein the frit is arranged on the inorganic insulating layer.
12. The device of claim 9 , wherein the first and second dam portions repel each other due to the first and second dam portions each comprising a plurality of magnetic particles.
13. The device of claim 9 , wherein the first and second dam portions are separated from each other by an interval.
14. The device of claim 9 , wherein a sum of a height of the first dam portion and a height of the second dam portion is less than a gap between the first and second substrates.
15. The device of claim 9 , wherein the filling material and the first and second dam portions repel each other due to the magnetic particles in each of the filling material and the first and second dam portions.
16. The device of claim 9 , wherein the filling material further comprises non-magnetic particles having no magnetism.
17. The device of claim 9 , wherein the first and second dam portions are separated from the sealant by an interval.
18. The device of claim 9 , wherein the sealant comprises a plurality of magnetic particles.
19. The device of claim 18 , wherein the sealant and the first and second dam portions repel each other due to the magnetic particles in the sealant and the magnetic particles in the first and second dam portions.
