Claim 0:
1. A light-emitting diode display module, comprising:
a first light-emitting diode, having a first operating voltage and having a first anode and a first cathode;
a second light-emitting diode, having a second operating voltage and having a second anode and a second cathode, wherein the second operating voltage is greater than the first operating voltage;
a third light-emitting diode, having the second operating voltage and having a third anode and a third cathode;
a scan block, receiving a high power supply voltage and a low power supply voltage, and being coupled the first anode, the second anode, and the third anode;
a voltage conversion block, receiving the high power supply voltage and the low power supply voltage to provide an auxiliary power supply voltage, wherein the auxiliary power supply voltage ranges from the high power supply voltage to the low power supply voltage;
a first sink block, receiving the high power supply voltage and the auxiliary power supply voltage, and being coupled to the first cathode to drive the first light-emitting diode; and
a second sink block, receiving the high power supply voltage and the low power supply voltage, and being coupled to the second cathode and the third cathode to drive the second light-emitting diode and the third light-emitting diode.
