Abstract
An ion writing system includes a writing unit and a calibration module. The writing unit includes an array of selectable electrode nozzles to direct ions onto passive e-paper to form a pattern of dots on the e-paper. The calibration module calibrates the writing unit for image optical intensity via information from a sensor.
Claims15
An external, contactless writing system for e-paper, the system comprising:
- a writing unit including an ion generator to generate airborne ions and an array of selectable electrode nozzles to direct the airborne ions onto a passive e-paper to form a pattern of dots on the passive e-paper;
- a processor;
- and
- a non-transitory memory storing machine readable instructions, executable via the processor, to calibrate the writing unit for image optical intensity of at least one of the respective dots, via information from a sensor, according to a total number of charges per dot parameter.
