Embodiment Construction

[0040] Figure 1A is a schematic structural view of an inkjet device according to a preferred embodiment of the present invention. Please refer to Figure 1A , the inkjet device 100 includes an ink storage tank 110 , an inkjet head 120 and a first magnetic field applying device 130 . Wherein, the ink storage tank is used for storing ink 112 , and the ink 112 is mixed with magnetic particles 114 . In one embodiment, the magnetic particle 114 is, for example, a diamagnetic material, a paramagnetic material, a ferrite magnetic material or other magnetizable materials, wherein the ferrite magnetic material is, for example, iron, cobalt and nickel. In addition, these magnetic particles 114 are nanoparticles, for example.

[0041] The inkjet head 120 is connected to the ink tank 110 , and the inkjet head 120 has a nozzle 122 and an actuator 124 , wherein the actuator 124 drives the ink 112 to eject from the nozzle 122 . It is worth mentioning that the actuator 124 is, for example,...

Abstract

The ink jet device includes ink storage tank, ink jet head and one first magnetic field unit. The ink storage tank holds ink with magnetic particles; the ink jet head connected to the ink storage tank has nozzle and actuator to drive ink for jetting automatically; and the first magnetic field unit set around the nozzle of the ink jet head makes the jetted ink concentrated in raised jetting precision. In addition, the present invention also discloses one kind of color filter plate and its making process.

Description

technical field [0001] The present invention relates to an inkjet device, a color filter substrate and a manufacturing method thereof, and particularly relates to an inkjet device controlled by a magnetic field, a color filter substrate and a manufacturing method thereof. Background technique [0002] At present, the manufacturing process of the color filter substrate is completed by ink-jet technology or photomicrography technology. The above-mentioned inkjet technology is to pressurize or heat the ink to generate a momentary high pressure to force the ink to be ejected from the nozzle of the inkjet head (printer head), where the ejected ink forms ink droplets and adheres to on the surface of the substrate. It should be noted that the ink ejected from the nozzles of conventional inkjet devices often produces main droplets and satellite droplets (sateLLite droplets), and the landing points of the main droplets and satellite droplets will be slightly different. As far as th...
