Abstract
An RGB LED uses three leads instead of four. The three RGB semiconductor chips are all connected to a common lead where they are held. One of the three RGB semiconductor chips is connected, in conventional fashion, to a second lead. The other two of the three RGB semiconductor chips are alternately connected to a third lead and wired so that only one will work at a time, depending upon whether a positive or negative current is applied. A controller controls the direct and alternating current applied to the three RGB semiconductor chips to produce the desired combined color for the RGB LED.
