Patent ID: 7488388

Claim:
An apparatus for fabricating a display device, the apparatus comprising: a rectangular substrate that has a section; a stage on which the rectangular substrate is loaded; a single dispenser that moves along an outline of the section on the rectangular substrate and from which a sealant is applied to the rectangular substrate using a jet nozzle ejecting the sealant to the rectangular substrate; a light detector that emits light toward the rectangular substrate and detects an amount of light reflected toward the detector in real-times; a controller that detects a position on the rectangular substrate that is to be covered with sealant but does not have the sealant, in accordance with a signal supplied from the light detector, and that generates a control signal based on the signal supplied from the light detector; a driver that moves the dispenser horizontally and vertically under control of the controller; and a guide line that guides the movement of the driver; and a supplier that supplies the sealant to the dispenser, wherein the single dispenser moves back to the position and reapplies the sealant to the rectangular substrate at the position along a trace of the sealant on the rectangular substrate based on the control signal, wherein the light detector includes a light-emitter emitting the light to the sealant applied to the rectangular substrate, and a light-receiver receiving light reflected from the rectangular substrate, wherein the jet nozzle is positioned between the light-emitter and a light-receiver.
