ADAPTIVE LIGHT EMITTING DIODE BAR EQUALIZATION |
摘要 |
Uniformity of light output from an LED printbar is achieved by current sensing or image sensing of auxiliary LEDs on the LED printbar. A photodetector measures the light output from the auxiliary LEDs and a comparator will compare the auxiliary LED data to determine if the entire LED printbar has to be compensated to make the light output more unifor m.
