Title:
METHOD FOR MANAGING LIFE OF LIQUID DROPLET DISCHARGE HEAD AND METHOD FOR MANUFACTURING LIQUID DROPLET DISCHARGE DEVICE AND ELECTROOPTICAL DEVICE
Document Type and Number:
Japanese Patent JP2005212192
Kind Code:
A
Abstract:
To provide a method for managing the life of a liquid droplet discharge head by which the occurrence of a discharge failure can previously be avoided, and a method for manufacturing a liquid droplet discharge device and an electrooptical device.
In the method for managing the life of a liquid droplet discharge head, the operational history of the liquid droplet discharge head 22 with a nozzle for discharging a liquid onto an object to which the liquid is discharged as a liquid droplet, is recorded in an IC chip 101. Further, the life of the liquid droplet discharge head 22 is decided based on the operational hysteresis.
