Claim 2:
3. The display device of claim 2, wherein the power voltage generator includes:
a power voltage generating block which generates the first power voltage and the second power voltage based on an input voltage and the voltage control signal, and controls the voltage level of the first power voltage based on the second power voltage and an analog voltage;
a power voltage supply which applies the input voltage to the power voltage generating block;
a reference current calculator which calculates a reference current based on a voltage level of the second power voltage and a reference power consumption lookup table;
a current sensing block which senses the power current and generates a voltage drop signal based on the current level of the power current and the reference current;
a voltage code generating block which outputs a power voltage code based on the voltage drop signal and a voltage code lookup table; and
a power voltage digital-to-analog converter block which generates the analog voltage based on the power voltage code.
