Abstract:

An ink cartridge having a piezoelectric jet module has an ink storage module having a hollow ink storage region, a piezoelectric jet module having a plurality of ink chambers and a connection circuit, and an ink channel connected to the ink storage module and to the piezoelectric jet module. The piezoelectric inkjet printhead has a bottom film and chamber walls which are obtained by applying a photosensitive polymer on a substrate on which a piezoelectric layer has been formed and carrying out photolithography.

International Classification:

B41J 204

US Classification:

347 71, 216 27, 347 47

Abstract:

A method of forming a nozzle plate of an inkjet print head. A silicon chip is provided with an activated device and a first film is formed on the silicon chip, with a first opening corresponding to the activated device. Then, a second film is formed on the first film. Next, a photoresist layer is formed on the second film, such that the photoresist layer has a second opening corresponding to the first opening. Next, the second film under the second opening of the photoresist layer is etched to form a via in the second film passing through the first opening.

International Classification:

B41J002/05

US Classification:

347/065000

Abstract:

An inkjet printhead chip is installed at the nose of an ink cartridge. Its structure includes a silicon substrate, a barrier layer, and a nozzle plate. The nozzle plate is formed with two parallel rows of inkjet nozzles. Two rows of ink channels roughly parallel to the inkjet nozzles and two rows of independent control circuits are provided among the silicon substrate, the barrier layer and the nozzle plate. The ink channels are disposed between the two rows of nozzles. The control circuits are configured to be on the outer sides of the two rows of nozzles. Using this structure of ink channels and control circuits, the inkjet printhead chip allows a larger area for attaching the nozzle plate. A flexible printed circuit is used to send external control signals from both sides of the chip to the control circuits, starting ink firing elements to eject ink and form patterns or texts on a nearby medium.
