Abstract

A reinforcement liquid jet device includes a nozzle unit that is spaced apart from a display panel by a predetermined interval and that jets a reinforcement liquid to a side of the display panel, a moving frame that is movably installed and the nozzle unit is coupled to the moving frame, a mask unit that is rotatably coupled to the moving frame, and a driving unit that is coupled to the moving frame and that rotates the mask unit.

First claim

What is claimed is:

1. A method of manufacturing a display panel, the method comprising:
disposing the display panel to have a predetermined angle with respect to the ground by placing the display unit in a supporting unit and then operating the supporting unit;
disposing a nozzle unit to be spaced apart from a side of the display panel by a predetermined interval by moving a moving frame;
disposing the nozzle unit and a portion of the display panel at a side of a mask unit, which mask unit is installed in the moving frame, by rotating the mask unit; and
spouting a reinforcement liquid to the side of the display panel through the nozzle unit while moving the moving frame.

2. The method of claim 1 , wherein during the spouting of the reinforcement liquid, the moving frame moves in a direction of a length of the display panel.

3. The method of claim 1 , wherein spouting the reinforcement liquid includes jetting a visible ray to a portion of the display panel through a vision unit that is coupled to the moving frame.

4. The method of claim 1 , wherein the mask unit includes:
a rotation unit that is rotatably coupled to the moving frame, and
a liquid splash prevention unit that is bent from the rotation unit.

5. The method of claim 4 , wherein a length of the rotation unit is equal to or greater than a distance from a center of rotation of the rotation unit to an end of the nozzle unit.

6. The method of claim 1 , further comprising cleaning the mask unit through a cleansing unit, which cleansing unit is coupled to the moving frame, by rotating the mask unit.

7. The method of claim 6 , wherein during the cleaning of the mask unit, a portion of the mask unit contacts the cleansing unit.
