发明名称 METHOD FOR RECOGNIZING IMAGE OF NOZZLE OPENING AND METHOD FOR CORRECTING LOCATION OF LIQUID DROPLET DISCHARGED USING THE SAME, METHOD FOR INSPECTING NOZZLE HOLE, DEVICE FOR RECOGNIZING IMAGE OF NOZZLE HOLE AND DEVICE FOR DISCHARGING LIQUID DROPLET INCLUDING THE SAME, METHOD FOR MANUFACTURING ELECTRO-OPTICAL DEVICE, ELECTRO-OPTICAL DEVICE, AND ELECTRONIC APPARATUS FOR RECOGNIZING IMAGE WITH SUPERIOR PRECISION
摘要 PURPOSE: A method for recognizing an image of a nozzle hole and a method for correcting a location of liquid droplet discharged using the same, a method for inspecting a nozzle hole, a device for recognizing an image of a nozzle hole and a device for discharging liquid droplet including the same, a method for manufacturing an electro-optical device, an electro-optical device, and an electronic apparatus are provided to recognize an image with superior precision. CONSTITUTION: An image recognizing device for photographing a nozzle hole of a liquid droplet discharging head in a state of discharging functional liquid includes a strobe, an image recognizing camera, a head driver, and a strobe driver. The strobe irradiates light onto a nozzle hole(53). The image recognizing camera photographs the nozzle hole(53) irradiated on to the nozzle hole(53). The head driver applies the driving waveform to the liquid droplet discharging head. The strobe driver emits light with respect to the strobe in synchronization with the application of the driving waveform. The image recognizing camera confronts a nozzle surface of the liquid droplet discharging head.
