Abstract

The invention relates to an ink jet device and a method for eliminating bubbles in an ink jet head. The ink jet device comprises an ink supply tank and at least one ink jet head, and at least one input pipe is connected between the ink supply tank and at least one ink jet head. The ink jet device also comprises at least one vent-pipe and at least one balance pipe. At least one vent-pipe is communicated with the air through a vent valve. At least one balance pipe is used for connecting with at least one input pipe and at least one vent pipe. At least one balance pipe is provided with a non return valve used for preventing the ink from flowing towards at least one input pipe form at least one vent pipe.

Description

technical field [0001] The invention relates to an ink-jet device, in particular to an ink-jet device for making a color filter and a method for removing air bubbles in an ink-jet head. Background technique [0002] Since the liquid crystal in a liquid crystal display (Liquid Crystal Display, LCD) is a non-active light-emitting component, the light source must be provided through the backlight, and the driving integrated circuit and the liquid crystal control form a black and white grayscale display, and then through the color The three color layers of red (Red, R), green (Green, G), and blue (Blue, B) of the color filter (Color Filter, CF) provide hue and form a color display screen, so the color filter is an important part of the liquid crystal display. Colorized key components. [0003] In the inkjet method, an inkjet device is used to spray ink containing RGB pigments into a black matrix on a substrate at the same time, and the ink is cured to form RGB color layer patte...
