METHOD AND DEVICE FOR MANUFACTURE OF COLOR FILTER, COLOR FILTER, DISPLAY DEVICE, DEVICE EQUIPPED WITH THE DISPLAY DEVICE, AND METHOD FOR DETERMINING NOZZLE HOLE AREA

摘要

PROBLEM TO BE SOLVED: To expand a margin for broken character and color mixing by selecting the best suited ink jet head for use in terms of a nozzle hole area from among ink jet heads with different nozzle hole areas according to the shape of a pixel to be formed on an object to be colored, when manufacturing a color filter by discharging an ink from the ink jet heads. ;SOLUTION: Three ink jet heads 55 to be used for a color filter manufacturing device 90 are provided so that the heads 55 correspond to three primary colors R, G, B. In addition to these ink jet heads 55, the device 90 comprises a heater board for heating the different color inks and a top plate to be placed on the heater board for covering. When manufacturing the color filter, a dot pattern is illuminated by a transmitted light, then is enlarged by a microscope and this enlarged dot pattern is entered to an image processing device through a CCD camera. In the image processing device, an image is binary-coded or processed by other means to seek the diameter or area of the image. Further, it is interpreted whether a state in which dots are spread is appropriate for the actual width (or the actual area) of pixels in the color filter. Next, the hole area of a head nozzle is expanded or shrunk in accordance with the interpretation results.;COPYRIGHT: (C)1999,JPO
