9. A display device comprising:
a display panel comprising a gate line, a data line, a first power line, a second power line, and a pixel connected to the gate line, the data line, the first power line, and the second power line;
a timing controller configured to generate a gate driving control signal, a data driving control signal, a power control signal, and a switch control signal based on a display period representing a time interval of frames;
a gate driver configured to provide a gate signal to the pixel through the gate line based on the gate driving control signal;
a data driver configured to provide a data signal to the pixel through the data line based on the data driving control signal;
a power supply that generates a first power voltage and a second power voltage lower than the first power voltage;
a charging pump unit configured to generate a first secondary power voltage and a second secondary power voltage lower than the first secondary power voltage to be adjusted with time during the display period based on the power control signal; and
a power selecting unit configured to connect the first power line and the second power line to the charging pump unit or the power supply based on the switch control signal.
