FEEDBACK CONTROL APPARATUS AND METHOD FOR AN EMISSIVE PRINTHEAD

摘要

The present invention uses an open loop feedback technique to control emissive pixels of a printhead of a printer. The open loop feedback technique involves integrating the light intensity of the emissive pixel over a predetermined period of time, averaging the integrated value, comparing the averaged value to a threshold value, and adjusting the input voltage to the OLED of the pixel based on the comparison.
