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 (22)

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.
