    • An ink jetting apparatus using electrostatic force, a manufacturing method thereof, and an ink providing method thereof are provided to facilitate the selection of ink regardless of color change due to heat as a heater is unnecessary by spraying ink with static power generated by electric potential difference between upper electrode and lower electrode. An ink jetting apparatus using electrostatic force comprises a lower electrode part(100), an upper electrode part(200), and a bonding layer(300). In the lower electrode part, a nozzle formed on the top of a first substrate, a lower electrode positioned inside the nozzle and an ink inflow path formed at the bottom of the first substrate. The upper electrode part comprises an upper electrode formed on the top of a second substrate and an ink discharging hole perforated from the bottom of the second substrate to the upper electrode. The bonding layer bonds the lower electrode and the upper electrode to arrange the nozzle and the ink discharging hole in a vertical direction. Meniscus is formed in the nozzle tip when static force generated by the electric potential difference between the upper electrode and the lower electrode is applied on the ink supplied to the nozzle through the ink inflow path and the ink having micro droplet size is discharged through the ink discharging hole of the upper electrode at the end of the meniscus.
    • 提供一种使用静电力的喷墨设备及其制造方法和墨水提供方法,以便随着加热器的颜色变化而无论颜色变化如何,通过喷涂由电位差产生的静电而不需要墨水 在上电极和下电极之间。 使用静电力的喷墨装置包括下电极部(100),上电极部(200)和接合层(300)。 在下部电极部中,形成在第一基板的顶部上的喷嘴,位于喷嘴内的下部电极和形成在第一基板的底部的墨水流入路径。 上电极部分包括形成在第二基板的顶部上的上电极和从第二基板的底部到上电极穿孔的排墨孔。 接合层结合下电极和上电极,以使喷嘴和排墨孔在垂直方向上布置。 当由通过墨水流入路径供给到喷嘴的墨水上施加由上部电极和下部电极之间的电位差产生的静电力时,在喷嘴尖端形成弯液面,并且具有微滴尺寸的墨水通过墨水排出 在半月板的末端放出上电极的孔。
