摘要： Disclosed is a sealant dispenser for more precisely dispensing a sealant onto a substrate, and a control method thereof. The sealant dispenser includes a stage on which a substrate is mounted; a nozzle for dispensing a sealant while making a relative motion with the substrate; a syringe coupled to the nozzle, for storing the sealant; and a distance sensor installed on both sides of a lower portion of the syringe, for measuring a vertical distance between a principal plane of the substrate and an outlet of the nozzle. According to the principles of the present invention, because the nozzle and the syringe have substantially the same central axis, the response speed of the sealant to be dispensed is increased and the start point and the end point of paste pattern are more precisely dispensed. Also, by minimizing the distance between the nozzle and a measuring point provided by the distance sensor, it becomes possible to dispense the sealant at higher precision.
