An inkjet printing apparatus for use in preparation of a display component, comprising an inkjet assembly, an ink cartridge configured to provide a jet printing fluid to the inkjet assembly, and a controller configured to control the printing process, wherein the inkjet assembly comprising at least one jet printing member having a first surface on which an inkjet port structure is formed, the inkjet port structure comprises at least one sub inkjet port, wherein

• the inkjet assembly further comprises a deflection member configured to provide a deflection force to a fluid emitted from the inkjet port structure and a control member configured to control operation of the deflection member,
• wherein the inkjet printing apparatus further comprises a waste collection device provided on the ink cartridge and located on a side of the inkjet port structure,
• wherein the waste collection device comprises a waste tank casing detachably connected to the ink cartridge, and a waste absorbent placed in the waste tank casing, wherein one side of the waste tank casing facing the inkjet port structure is open,
• wherein the waste absorbent is provided on two sides around the inkjet port structure,
• wherein the deflection member comprises one first electrode and two second electrodes,
• wherein the first electrode is disposed opposite to each second electrode of the two second electrodes, and the inkjet port structure is formed between the first electrode and the each second electrode of the two second electrodes disposed opposite to the first electrode,
• wherein the first electrode has a thickness greater than the each second electrode of the two second electrodes,
• wherein a surface of the nozzle plate facing away from the first surface is a sec wherein the inkjet assembly further comprises an inkjet fluid guide layer having fluid guide channels formed in the inkjet fluid guide layer;
• wherein the fluid guide channels comprise at least one first-phase channel, at least one second-phase channel, and at least one mixed-phase channel;
• wherein the first-phase channel and the second-phase channel are independent of each other, and in communication with the at least one mixed-phase channel, respectively;
• and
• wherein the mixed-phase channel is in communication with the sub inkjet ports
