Abstract
An inkjet printhead includes a substrate having an ink chamber which is filled with ink to be ejected, a nozzle plate formed on the substrate in a position corresponding to the ink chamber, and a heat generating resistor installed in the ink chamber and formed of TiNx, where x ranges from 0.2 to 0.5, to generate ink bubbles in the ink by generating heat.
Claims20
An inkjet printhead, comprising:
- a substrate having an ink chamber which is filled with ink to be ejected;
- a nozzle plate formed on the substrate in a position corresponding to the ink chamber;
- and
- a heat generating resistor formed in the ink chamber to generate bubbles in the ink by providing heat, the heat generating resistor being formed of titanium nitride TiNx, where x ranges from 0.2 to 0.5.
1 more element
An inkjet printhead, comprising:
- a substrate;
- a nozzle plate having a plurality on nozzles to eject ink;
- and
- a plurality of nozzle units formed between the substrate and the nozzle plate corresponding to the plurality of nozzles, each of the plurality of nozzles units including:
- an ink chamber filled with ink to be ejected through the corresponding nozzle from the plurality of nozzles;
- and
- a heat generating resistor disposed in the ink chamber opposite to the nozzle to heat the ink when connected to a power supply, the heat generating resistor being made of TiNx, where x is in a range of between 0.2 and 0.5.
4 more elements
A method of ejecting ink through nozzles of an inkjet printhead, the method comprising:
- heating ink in the ink above a boiling temperature using heat generating resistors corresponding to each of the nozzles, the heat generating resistors being made of a TiNx compound, where x is between 0.2 and 0.5.
