Abstract

An organic light emitting diode display having a display panel comprising a first substrate and a second substrate disposed facing the first substrate, the first substrate comprising a display area and a pad area, a buffer member disposed on one surface of the first substrate, the buffering member having a buffer layer and an adhesive layer formed on at least one surface of the buffer layer, and a bezel or a case accommodating the display panel and buffer member.

Claims (22)

1. An organic light emitting diode display, comprising:

a first substrate and a second substrate disposed facing the first substrate, the first substrate comprising a display area and a pad area;

a buffer member disposed on one surface of the first substrate;

a bezel for accommodating a display panel comprising the first substrate and the second substrate; and

a case enclosing the bezel;

the buffer member comprising a first buffer member and a second buffer member, the first buffer member being disposed between the display panel and the bezel and the second buffer member being disposed between the bezel and the case; and

each said buffer member comprising a buffer layer and an adhesive layer formed on at least one surface of the buffer layer.

2. The organic light emitting diode display of claim 1 , the buffer layer comprising one of sponge and urethane.

3. The organic light emitting diode display of claim 1 , the buffer layer having a thickness ranging from 0.1 mm to 0.3 mm, and the adhesive layer having a thickness ranging from 0.02 mm to 0.04 mm.

4. The organic light emitting diode display of claim 1 , the display panel being fixed to the bezel by the first buffer member.

5. The organic light emitting diode display of claim 4 , the adhesive layer being comprised of a first adhesive layer and a second adhesive layer respectively formed on opposite surfaces of the buffer layer, the first adhesive layer being attached to the display panel and the second adhesive layer being attached to the bezel.

6. The organic light emitting diode display of claim 4 , one surface of the buffer member being in contact with and attached to an inner bottom portion of the bezel, the buffer member being attached to the entire one surface of the first substrate.

7. The organic light emitting diode display of claim 4 , the buffer member being comprised of a bottom portion and a skirt portion protruding from an edge of the bottom portion, the skirt portion being bent perpendicular to the bottom portion so as to combine with and cover corresponding edges of the display panel, the combined display panel and buffer member being contained in the bezel so as to cover inside portions of the bezel.

8. The organic light emitting diode display of claim 4 , the bezel being made of a metal.

9. The organic light emitting diode display of claim 1 , the adhesive layer comprising a first adhesive layer and a second adhesive layer respectively formed on opposite surfaces of the buffer layer, the first adhesive layer being attached to the display panel and the second adhesive layer being attached to the case.

10. The organic light emitting diode display of claim 1 , the buffer member being attached to a portion of an upper surface of the second substrate and being further attached to a bottom surface of the first substrate.

11. The organic light emitting diode display of claim 1 , wherein the case is made of plastic.

12. The organic light emitting diode display of claim 1 ,

the case having a thickness ranging from 0.4 mm to 1.5 mm.

13. The organic light emitting diode display of claim 12 , the case comprising at least one of a resin-based material comprising polycarbonate (PC), and a metal-based material comprising stainless steel (SUS), magnesium (Mg), aluminum (Al), and their alloys.

14. The organic light emitting diode display of claim 12 , the case comprising a bottom portion contacting the buffer member and a side wall portion protruding and extending from the bottom portion and enclosing at least part of sides of the display panel, the side wall portion being spaced apart a predetermined distance from the sides of the display panel.

15. The organic light emitting diode display of claim 14 , the predetermined distance being greater than 0.5 mm.
