Claim 17:
18. A light-emitting diode (LED) matrix, comprising:
a plurality of LEDs arranged in rows and columns, the plurality of LEDs including a first LED configured to emit light having a first color,
a second LED configured to emit light having the first color, and a third LED configured to emit light having a second color different from the first color; a mirror transistor coupled to a current source;
two driving transistors coupled in parallel and configured to receive current from the mirror transistor;
a first modulator coupled in series with the first LED and configured to receive a first current from one of the two driving transistors, a first end of the first LED directly coupled to one of the two driving transistors, a second end of the first LED directly coupled to a first end of the first modulator, a second end of the first modulator coupled to a low rail; and
a second modulator coupled in series with the second LED and configured to receive a second current from the other of the two driving transistors, a first end of the second LED directly coupled to the other of the two driving transistors, a second end of the second LED directly coupled to a first end of the second modulator, a second end of the second modulator coupled to the low rail.
