Abstract: Disclosed are an ink-jet printing head, an ink-jet printing method using the ink-jet printing head and an ink-jet printing device including the ink-jet printing head. The ink-jet printing head includes a chamber for accommodating ink and nozzle sets provided on a sidewall of the chamber where ink is sprayed. The nozzle sets are used for ink-jet printing on pixels at different positions, respectively. Each of nozzle sets includes sub-nozzles and the sub-nozzles in each nozzle set can spray different volumes of ink. In the printing head, by providing sub-nozzles having different ink spraying volumes in each nozzle set, ink droplets having desirable volumes can be sprayed from nozzle sets such that total volumes of ink droplets sprayed at different positions from nozzle sets could be more accurate. Therefore, a thickness of a film layer formed by ink-jet printing can be flexibly controlled and adjusted, while having a significantly improved accuracy.
