Abstract

The present invention provides a device and a method for measuring relative positioning, in which a nozzle position and the image-forming point of a laser which emits light from a laser-displacement sensor are imaged by means of an imaging device in such a way as to be able to rapidly and accurately measure the relative positioning of the outlet port of the nozzle and the image-forming point of the laser.

Description

technical field [0001] The invention relates to a device and a method for measuring the relative position between a nozzle discharge opening of a head unit and a light spot of a laser distance sensor. Background technique [0002] In general, a flat panel display (FPD) is a video display that is thinner and lighter than conventional televisions or monitors that use cathode ray tubes. Examples of FPDs that have been developed and used are liquid crystal displays (LCDs), plasma display panels (PDPs), field emission displays (FEDs), and organic light emitting diodes (OLEDs). [0003] Among them, the LCD is a display that independently supplies data signals based on image information to liquid crystal cells arranged in a matrix to control light transmittance of the liquid crystal cells to display desired images. Since the LCD has advantages of being thin, light, low power consumption, and low operating voltage, the LCD has been widely used. A method of manufacturing a liquid c...
