Adaptive light emitting diode bar equalization

   
   

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 uniform.

A uniformidade da saída clara de um diodo emissor de luz printbar é conseguida pela corrente que deteta ou detetar da imagem de diodos emissores de luz auxiliares no diodo emissor de luz printbar. Um photodetector mede a saída clara dos diodos emissores de luz auxiliares e um comparador comparará os dados auxiliares do diodo emissor de luz para determinar se o diodo emissor de luz inteiro printbar tiver que ser compensado para fazer a saída clara mais uniforme.
