Abstract

The invention provides a dispenser apparatus and a method of controlling the same.The dispenser apparatus comprises a discharge unit equipped with a nozzle for discharging the raw material to a substrate, a gap sensor for measuring the gap between the nozzle of the discharge unit and the substrate, a support unit, a sliding unit and a head block.The discharge unit is arranged on one side face of the support unit and the gap sensor is arranged on another side face of the support unit.The sliding unit is arranged between the support unit and the discharge unit, so that the discharge unit is lifted by the reaction due to the collision nozzle of the discharge unit and the substrate.The head block comprises a displacement detection unit for detecting the movement of the discharge unit due to the lifting of the sliding unit.Therefore, when the nozzle of the discharge unit collides with the substrate, a sliding part connected with the discharge unit is operated by means of the reaction.The discharge unit is lifted by the operation of the sliding part and the movement of the discharge unit is detected by the displacement detection unit.

Description

technical field [0001] The present invention relates to a dispenser device and a control method thereof, and more specifically, the present invention relates to a dispenser device and a control method thereof whose measurement reference point (measurement reference point) of a gap sensor (gap sensor) is relatively easy to be set . Background technique [0002] A cathode ray tube (CRT) has been used as a related art display device. However, there is a limitation that the CRT is bulky and heavy. Recently, flat panel displays (FPD) such as liquid crystal display device (liquid crystal display device, LCD), plasma display panel (plasma display panel, PDP) and organic light emitting device (organic light emitting device, OLED) are widely used. Used as a display device. FPDs are characterized by light weight, thin profile, and low power consumption. [0003] In the case of this type of FPD, a pair of flat type substrates are bonded to each other. That is, a lower substrate an...
