Abstract

A display panel transfer device includes: an absorption part disposed in parallel with a first direction; a supporting part disposed in parallel with a second direction crossing the first direction; and a moving part, where the absorption part includes a plurality of absorbers disposed in parallel with a third direction crossing the first and second directions, and the supporting part includes a transfer stage disposed in parallel with the first direction.

First claim

What is claimed is:

1. A display panel transfer device configured to transfer a display panel, comprising:
an absorption structure comprising a first body disposed such that a longest dimension of the first body is in parallel with a first direction; and
a supporting structure having a second body disposed such that a longest dimension thereof is in parallel with a second direction crossing the first direction,
wherein the absorption structure includes an absorber extending directly from the first body such that a longest dimension of the absorber is in parallel with a third direction crossing the first and second directions, and
wherein the supporting structure includes a transfer stage extending from the second body such that a longest dimension of the transfer stage is in parallel with the first direction,
wherein the transfer stage is configured to move in the second direction,
wherein the absorber is configured to support a first portion of the display panel from above, and the transfer stage is configured to support a second portion of the display panel from below, the first and second portions not overlapping along the third direction, and
wherein the display panel transfer device is configured to transfer the display panel while the absorber and the transfer stage simultaneously support the first and second portions of the display panel.

2. The display panel transfer device of claim 1 , wherein
the absorber is configured to move in the third direction.

3. The display panel transfer device of claim 1 , wherein
the transfer stage is configured to move in the second direction with respect to the second body.

4. The display panel transfer device of claim 1 , wherein
the absorber is configured to contact the display panel, and configured to subsequently combined with the display panel by providing a vacuum inside the absorber.

5. The display panel transfer device of claim 4 , wherein
the transfer stage is configured to move toward under the display panel combined with the absorber to support the display panel.

6. The display panel transfer device of claim 1 , further comprising:
a moving structure configured to move the supporting structure and the absorption structure from an initial position to another position.

7. The display panel transfer device of claim 1 ,
wherein the absorber is configured to absorb the display panel than move in the third direction to lift the display panel in the third direction, and
wherein the transfer stage is configured to move in the second direction from a first position in which the transfer stage is offset from the absorbers to a second position in which the transfer stage overlaps the absorbers such that the transfer stage is positioned under the display panel lifted by the absorber.

8. The display panel transfer device of claim 1 ,
wherein the first body extends in the first direction from a side of the second body.

9. The display panel transfer device of claim 1 ,
wherein the transfer stage extends in the first direction from an underside of the second body.

10. The display panel transfer device of claim 1 ,
wherein the transfer stage is a flat shape having a thickness thereof in the third direction.
