Display apparatus and driving method thereof

A display apparatus for displaying image information corresponding to display data, the apparatus comprising:

• display pixels, each having a light emitting element;
• and
• a drive circuit for making each of the light emitting elements emit a light having brightness according to the display data, and including a plurality of power source circuits and a selecting circuit,
• wherein each of the plurality of power source circuits generates a first voltage used as a light emission drive voltage to be supplied to the display pixels to flow a drive current according to the display data to each of the light emitting elements and a second voltage to set a signal level of a control signal to perform drive control of each of the display pixels and generates voltages of different values as the first voltage and different values as the second voltage, respectively;
• and
• the selecting circuit selects any one of the plurality of power source circuits according to a display state set to the display pixels and causes the selected power source circuit to generate the first voltage and the second voltage.
