Abstract
When we use halftone as the method to adjust the brightness of an LED array, there may be a difference in utilization among the LEDs which may cause a high utilization of a particular one, easily damaging and reducing the life of the array. In this paper we therefore propose a shift method by using different halftone patterns with complement in the LED array to achieve uniform utilization of each LED.
