Abstract:
1. A method of controlling a plurality of light emitting diode (LED) strings in a video display, each of the LED strings being associated with a channel, the method comprising: shifting digital data identifying one of the channels into a channel prefix register; shifting digital data identifying a function within the one of the channels into a function prefix register; shifting digital data representing a value of the function within the one of the channels into a data register; and using the data identifying the one of the channels and the data identifying the function within the one of the channels to apply the value of the function to an LED string associated with the one of the channels by copying the data from the data register to a preload latch at a first rate and copying the data from the preload latch to an active latch at a second rate that is less than the first rate.
