Organic light emitting display
View Patent ↗Disclosed is an organic light emitting display. The organic light emitting display includes a display panel including a first substrate in which an organic light emitting diode is formed, a second substrate arranged on the top of the first substrate and a sealing material for combining the first substrate with the second substrate. The device includes a bezel including a lower surface and a plurality of sidewalls extending from edges of the lower surface, wherein a space for receiving the display panel is defined by the lower surface and the sidewalls. The device further includes a reinforcing lattice arranged between the display panel and the bezel.
1. An organic light emitting display device comprising:
a display panel comprising a first substrate, a second substrate, and an array of organic light emitting pixels interposed between the first and second substrates;
a backing frame comprising a base plate and a plurality of side walls extending from edges of the base plate, wherein the base plate and the plurality of side walls in combination accommodate the display panel such that the first substrate opposes the base plate and the side walls oppose edges of display panel; and
an insert frame interposed between the base plate and the first substrate, wherein the insert frame comprises a plurality of openings allowing the base plate and the first substrate to face each other therethrough;
wherein the plurality of side walls comprises a first side wall opposing a side of the display panel, wherein the first side wall comprises a first wall portion, a second wall portion and a connecting portion interconnecting the first and second wall portions, and wherein the first wall portion is interposed between the second wall portion and the side of the display panel.
2. The device of claim 1 , wherein the insert frame comprises a meshed structure that defines the plurality of openings.
3. The device of claim 1 , wherein the insert frame comprises a plurality of substantially parallel rods.
4. The device of claim 1 , wherein the insert frame comprises a first rod and a second rod which are substantially parallel and a plurality of interconnecting rods, and wherein each of the plurality of interconnecting rods interconnects the first and second rods.
5. The device of claim 4 , wherein the plurality of interconnecting rods are substantially parallel to one another.
6. The device of claim 4 , wherein the insert frame further comprises one or more additional interconnecting rods which interconnect two of the plurality of interconnecting rods.
7. The device of claim 4 , wherein the opening is a substantially rectangular.
8. The device of claim 1 , wherein the insert frame substantially prevents the first substrate from contacting the base plate.
9. The device of claim 1 , wherein the first substrate and the base plate does not contact each other through the plurality of openings.
10. The device of claim 1 , wherein the first substrate comprises a surface facing the base plate, wherein the base plate comprises a surface facing the first substrate, and wherein the surfaces are substantially parallel to each other.
11. The device of claim 1 , wherein the insert frame has a thickness in a direction perpendicular to a surface of the base plate facing the first substrate, and wherein the thickness is about 0.03 to about 0.15 mm.
12. The device of claim 1 , wherein the backing frame comprises a material selected from the group consisting of metal and polymeric resin.
13. The device of claim 1 , wherein the insert frame comprises at least one selected from the group consisting of stainless steel, magnesium, magnesium alloy, aluminum, polyethylene, protactinium, polymethylmetacrylate, ABS resin, aromatic liquid crystal polymer, polycarbonate and polyurethane.
14. The device of claim 1 , further comprising an intervening frame comprising an intervening portion interposed between the first side wall portion and the side of the display panel.
15. A method of making an organic light emitting display device, the method comprising:
providing a backing frame comprising a base plate and a plurality of side walls;
arranging a display panel, wherein the display panel comprises a first substrate, a second substrate, and an array of organic light emitting pixels interposed between the first and second substrates, such that the base plate and the plurality of side walls in combination accommodate the display panel and that the first substrate opposes the base plate and that the side walls oppose edges of the display panel; and
interposing an insert frame between the base plate and the first substrate, wherein the insert frame comprises a plurality of openings allowing the base plate and the first substrate to face each other therethrough;
wherein the plurality of side walls comprises a first side wall opposing a side of the display panel, wherein the first side wall comprises a first wall portion, a second wall portion and a connecting portion interconnecting the first and second wall portions, and wherein the first wall portion is interposed between the second wall portion and the side of the display panel.
16. The method of claim 15 , wherein interposing comprises placing the insert frame on the backing frame and arranging the backing frame and the display panel such that the insert frame is interposed between the base plate and the first substrate.
17. The method of claim 15 , wherein the insert frame comprises a meshed structure that defines the plurality of openings.
18. The method of claim 15 , wherein the insert frame comprises a plurality of substantially parallel rods.
19. The method of claim 15 , wherein the insert frame substantially prevent the first substrate from contacting the base plate.
