Problems solved by technology

Since the volume of each pixel area on the substrate is on the order of microns, if the ink remains on the nozzle, the remaining ink will hinder the next ejection of the ink. In this way, it is difficult to control the amount of ink ejection next time, and it is difficult to Ensure the uniformity of each color layer
In addition, when the nozzle is in the standby state, the ink in the nozzle will volatilize, and the dry ink will block the nozzle and the ink will not be ejected smoothly

Description

【Technical field】 [0001] The invention relates to a nozzle maintenance device, in particular to a nozzle maintenance device of an inkjet device used for manufacturing color filters. 【Background technique】 [0002] Since the liquid crystal display (Liquid Crystal Display, LCD) is a non-active light-emitting component, the light source must be provided through the internal backlight, and the driver IC and LCD control are used to form a black and white grayscale display, and then through the color filter The red (R), green (G) and blue (B) color layers of the color filter (ColorFilter) provide hue and form a color display screen, so the color filter is a key component of the colorization of the liquid crystal display. [0003] The ink-jet method is to use an ink-jet device to simultaneously spray ink containing RGB color layers into a black matrix on a glass substrate, and the ink droplets are dehydrated to form colored RGB color layer patterns on the substrate. The RGB color ...
