1071 through the nozzle 10720. Accordingly, the sealant 10715 of the pattern having no inlet is dispensed to the substrate 1071.
However, the related art sealant dispensing method has the following disadvantages.
First, because the sealant 10715 has a particular viscosity, the sealant 10715 may coagulate in the end of the nozzle 10720 of the dispenser. Thereafter, when the sealant material is supplied to the starting point (s) of the substrate 1071 through the nozzle 10730, the coagulated sealant is discharged to the starting point (s) of the substrate 1071. In addition, because the dispenser moves along the arrow direction from the starting point (s) of the substrate 1071, and then turns back to the starting point (s) of the substrate 1071, the coagulated sealant 10715 may be excessively dispenseda dispenser according to the related art.
The dispenser is provided with a syringe 10810, a nozzle 10820, and a dispensing tube 10830. The syringe 10810 has a sealant 10815 therein. The nozzle 10820 is connected to a lower end of the syringe 10810 to supply the sealant 10815 to a substrate 1081. The dispensing tube 10830 is connected to an upper end of the syringe 10810 to discharge the sealant 10815 through the nozzle 10820 by applying a pressure to the syringe 10810.
A sealant forming method using the above dispenser will now be explained.
The dispenser moves along an arrow direction from a starting point(s) of the substrate 1081, and then turns back to the starting point(s) of the substrate 1081. During the movement of the dispenser, a predetermined
