Abstract

An organic light emitting display assembly includes a body frame and a cap frame that assembly to secure an organic light emitting diode panel with the assembled frame. A gap is present between a perimeter edge of the organic light emitting diode panel and the body frame to allow for convenient placement of the panel in the frame. The cap frame, attached over the body frame via an insertion groove, includes a cap horizontal portion that covers a top surface of the body vertical portion. One side surface of the cap horizontal portion of the cap frame covers the gap between the organic light emitting diode panel and the body frame.

Claims

1. An organic light emitting display assembly comprising:

an organic light emitting diode panel comprising a side surface, a front surface, and a rear edge surface opposing the front surface;

a body frame disposed about the organic light emitting diode panel, the body frame comprising;

a body vertical portion surrounding the side surface of the organic light emitting diode panel, the body vertical portion including a first vertical part and a second vertical part that together define an insertion groove, the first vertical part of the body vertical portion and the side surface of the organic light emitting diode panel defining a gap therebetween;

a body horizontal portion perpendicularly connected to the body vertical portion, the body horizontal portion supporting the rear edge surface of the organic light emitting diode panel;

a cap frame comprising;

a cap vertical portion configured for insertion into the insertion groove of the body vertical portion of the body frame; and

a cap horizontal portion perpendicularly connected to the cap vertical portion, the cap horizontal portion having a first side surface that extends over the gap defined by the first vertical part and the side surface of the organic light emitting diode panel.

2. The organic light emitting display assembly of claim 1, wherein a width of the first side surface of the cap frame is from 1.5 to 2.5 times a thickness of the first vertical part of the body frame.

3. The organic light emitting display assembly of claim 1, wherein the insertion groove defined by the first vertical part and the second vertical part of the body vertical portion includes a first width at a first vertical point within the insertion groove, a second width greater than the first width at a second vertical point within the insertion groove, and a third width less than the second width and greater than the first width at a third vertical point within the insertion groove.

4. The organic light emitting display assembly of claim 3, wherein the cap vertical portion has a first thickness corresponding to the first width of the insertion groove at a first vertical point of the cap vertical portion, a second thickness corresponding to the second width of the insertion groove at a second vertical point of the cap vertical portion, and a third thickness corresponding to the third width of the insertion groove at a third vertical point of the cap vertical portion.

5. The organic light emitting display assembly of claim 1, wherein the cap horizontal portion includes a second side surface having a width corresponding to a width of the second vertical part of the body frame.

6. The organic light emitting display assembly of claim 1, wherein the first vertical part of the body vertical portion comprises a top end opposite the body horizontal portion, the top end including a chamfer adjacent to the insertion groove.

7. The organic light emitting display assembly of claim 1, wherein the cap vertical portion comprises a bottom end opposite the cap horizontal portion, the bottom end including a chamfer on a side of the cap vertical portion corresponding to the first side surface of the cap horizontal portion.

8. The organic light emitting display assembly of claim 1, wherein the body horizontal portion comprises a first surface proximate to the organic light emitting diode panel and a second surface opposite the first surface, the second surface of the body horizontal portion defining a step difference.

9. The organic light emitting display assembly of claim 8, further comprising a bottom frame having a height corresponding to a height of the step difference.

10. An organic light emitting display assembly comprising:
