A syringe for fabricating a liquid crystal display panel is provided. The syringe includes a body, a plurality of nozzles, and a connection portion. The body portion has a dispensing material contained therein. The plurality of nozzles supply the dispensing material received from the body portion to a substrate of the liquid crystal display panel. The connection portion are provided on a bottom surface of the connection portion and couples the nozzles with the body portion.

Syringe for fabricating liquid crystal display panel

A dispenser for a liquid crystal display panel includes a syringe having a nozzle provided at an end thereof, a body in which the syringe is mounted, a vertical driving stepping motor for moving the body in a vertical direction, a first sensor for detecting whether the nozzle of the syringe is in contact with a substrate, a second sensor for detecting a gap distance between the nozzle and the substrate, and a main unit for controlling the vertical driving stepping motor in response to an output from the second sensor to obtain a desired gap distance between the nozzle and the substrate.

A dispenser for a liquid crystal display panel includes a substrate on which at least one image display is formed, a table on which the substrate having at least one image display part is loaded, and at least one syringe horizontally movable to change position in relation to the table for supplying a sealant on the substrate to form a seal pattern.

Apparatus for aligning dispenser system, method of aligning dispenser system, and dispenser alignment system

A dispenser is provided for fabricating a liquid crystal display panel. The dispenser includes at least one dispensing unit to supply a dispensing material on a substrate, at least one support member to support and align the dispensing unit, and a plurality of syringes mounted on each dispensing unit.

Dispenser for fabricating a liquid crystal display panel

A seal pattern structure for a liquid crystal display panel is disclosed. Because an overlap portion of the seal pattern that encompasses in a closed form the outer edge of the image display part is minimized, excessive distribution of sealant at the seal pattern overlap portion may be prevented. The liquid crystal display panel including the seal pattern includes a substrate having at least one image display part; a start pattern formed from a point spaced apart from the image display part to a point adjacent to an outer edge of the image display part; a main pattern connected to the start pattern and encompassing the outer edge of the image display part; and an end pattern connected to the main pattern and formed from the outer edge of the image display part to a point spaced apart from the image display part, wherein a connection part between the start pattern and the main pattern and a connection part between the main pattern and the end pattern cross each other. A method of forming a seal pattern on a substrate for a liquid crystal display panel is also disclosed.
