Abstract

A cell cutting device and a cell cutting method are disclosed. The cell cutting device includes a loading stage configured to load a display sheet including a plurality of display cells, a rotation driving unit connected to the loading stage and configured to rotate the loading stage and to separate the display sheet into the plurality of display cells, and a position change unit connected to the loading stage and configured to change a position of the loading stage.

Claims

1. A cell cutting method comprising:

loading a display sheet comprising a plurality of display cells onto a loading stage;

separating the plurality of display cells from each other by rotating the loading stage in one direction;

rotating the loading stage in a direction opposite to the one direction; and

removing a dummy region of each of the plurality of separated display cells by using a dummy removal unit.

2. The cell cutting method of claim 1, wherein

the loading stage comprises a plurality of loading stages arranged to correspond to the display cells, and

the cell cutting method further comprises separating the plurality of loading stages from each other in a longitudinal direction of the display sheet.

3. The cell cutting method of claim 1, wherein the loading of the display sheet comprises adhering the display sheet and the plurality of display cells to the loading stage.

4. The cell cutting method of claim 1, wherein

the loading stage comprises a plurality of loading stages arranged to correspond to the display cells, and

the rotating of the loading stage in the one direction comprises rotating the plurality of loading stages in sequential order.

5. The cell cutting method of claim 1, wherein

the loading stage comprises a plurality of loading stages arranged to correspond to the display cells, and

in the rotating of the loading stage in the one direction, rotation angles of the plurality of loading stages differ from each other.
