1. A driving controller comprising:
a memory, which stores an input image signal in response to a control signal;
a scan signal generator, which outputs an internal scan signal in response to the control signal; and
a multiplexer, which outputs one of the input image signal and a storage image signal as an output image signal in response to the control signal and the internal scan signal, wherein the storage image signal is provided from the memory,
wherein the memory outputs the storage image signal in response to the internal scan signal,
wherein the control signal includes a vertical synchronization signal, and
wherein the scan signal generator outputs the internal scan signal in response to the vertical synchronization signal.
