LIQUID DROPLET EJECTION METHOD, LIQUID DROPLET EJECTION DEVICE, NOZZLE ABNORMALITY DETERMINATION METHOD, DISPLAY DEVICE, AND ELECTRONIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a liquid ejection method which can promptly and reliably detect an abnormality of a nozzle. SOLUTION: An ejection head includes a plurality of nozzles. Regarding the nozzles, an images of the inside and the periphery of each of the nozzles is captured by a camera unit 24. A captured image processing unit 161 converts the captured image into an image which can recognize at least one of a state of a meniscus inside the nozzle, the shape of a nozzle opening, and states of surface films formed inside and outside the nozzle; and sends the converted image to a comparison determination unit 164. The comparison determination unit 164 compares the processed image with a reference image which is previously stored in a determination condition storing unit 163. As a result, the quality (nozzle abnormality) of an ejection performance of the objective nozzle is determined. COPYRIGHT: (C)2005,JPO&NCIPI
