fewer segments are “ON,” each “ON” output drops more
voltage and current. For the best case of six segments (a
“111” display) to worst case (a “1888” display) the resistor
will change about 230mW, while a circuit without the resistor
will change about 470mW. Therefore, the resistor will re-
duce the effect of display dissipation on reference voltage
drift by about 50%.
The change in LED brightness caused by the resistor is
almost unnoticeable as more segments turn off. If display
brightness remaining steady is very important to the de-
signer, a diode may be used instead of the resistor.
