Abstract

An apparatus for cutting a flat display panel to prevent a light emitting surface of the flat display panel from becoming defective and contaminated while cutting the flat display panel is disclosed. The apparatus for cutting a flat display panel includes a stage to support a rear substrate of a flat display panel, a scribing support block to support a front substrate the flat display panel, a cutter to scribe the rear substrate of the flat display panel, and a scrap breaker to grip a scrap portion of the flat display panel that is to be separated from the flat display panel after cutting process of the flat display panel.

Claims

1. An apparatus for cutting a flat display panel, comprising:

a stage for supporting a rear substrate of the flat display panel;

a scribing support block disposed over the flat display panel and supporting the flat display panel while the flat display panel is being cut;

a cutter to scribe the flat display panel; and

a scrap breaker to grip a scrap portion of the flat display panel that is to be separated from the flat display panel after cutting the flat display panel.

2. The apparatus of claim 1, wherein the scribing support block is disposed to be aligned to one edge of a front substrate of the flat display panel to support the front substrate.

3. The apparatus of claim 2, wherein the scribing support block has a length that is substantially the same as a length of the one edge of the front substrate of the flat display panel.

4. The apparatus of claim 3, wherein the scribing support block is connected to a first driving member that is disposed substantially perpendicular to the stage, the first driving member moving the scribing support block in a direction perpendicular to the front substrate.

5. The apparatus of claim 1, wherein the cutter includes a wheel, the cutter scribing the rear substrate of the flat display panel in a direction along an edge of the scribing support block.

6. The apparatus of claim 5, wherein the wheel is connected to a second driving member that moves the wheel in a direction perpendicular to the rear substrate.

7. The apparatus of claim 1, wherein the scrap breaker comprises:

a cup to vacuum-grip the scrap portion of the flat display panel;

a delivery member holding the cup and applying a vacuum to the cup; and

a third driving member connected with the delivery member to move the delivery member and the cup in a direction perpendicular to the rear substrate.

8. The apparatus of claim 1, wherein the flat display panel is formed as an organic light emitting diode (OLED) display.

9. The apparatus of claim 1, wherein the front substrate of the flat display panel includes a light emitting surface of the flat display panel.

10. An apparatus for cutting a flat display panel, comprising:

a stage to support a rear substrate of an organic light emitting diode (OLED) display;

a scribing support block to support a front substrate of the OLED display;

a cutter to scribe the rear substrate of the OLED display; and

a scrap breaker to grip a scrap portion of the OLED display that is to be separated from the rear substrate after cutting the OLED display.

11. The apparatus of claim 10, wherein the scribing support block is disposed to be aligned to one edge of a front substrate, and the scribing support block has a length that is substantially the same as a length of the one edge of the front substrate of the OLED display.
