Abstract: An arrayed electrohydrodynamic printhead without the extraction electrodes is provided. A printhead is formed by an ink cartridge, a flow channel plate, a nozzle plate, a control electrode layer. The ink cartridge includes an ink inlet, an ink outlet, an installation hole, a flow channel layer inlet, flow channel layer outlet. The flow channel plate has the functions of guiding the ink to flow into the nozzle plate and increasing the potential difference between the nozzles, and includes a flow channel inlet, a flow channel outlet, a drainage channel, and a microfluidic channel. A body of the nozzle plate includes nozzles and nozzle electrodes. The microfluidic channel forms a voltage division unit between each nozzle, so that the voltage on the triggered nozzle is dispersed in the flow channel without affecting other nozzles, and independent and controllable injection of each nozzle is thereby achieved.

Abstract: An electrohydrodynamic inkjet printing device, including: a support part; a jet printing module; a substrate bearing and moving module; and a roll-to-roll thin film conveying module. The jet printing module is disposed on the support part and includes a nozzle for ejecting printing fluid onto a substrate for pattern printing. The substrate bearing and moving module is disposed on the support part, and fixedly bears a rigid substrate as the substrate for pattern printing, and drives the rigid substrate to move with respect to the jet printing module. The roll-to-roll thin film conveying module is disposed on the support part, and transfers a flexible thin film as the substrate for pattern printing, and drives the flexible film to move with respect to the jet printing module.
