Abstract:
A light emission driving circuit includes a driving circuit configured to output a light emission driving signal to a first output terminal and output a switching signal to a first node in response to clock signals and a first carry signal, and a first masking circuit configured to output a second carry signal to a second output terminal in response to a masking clock signal, the light emission driving signal, and the switching signal. The masking clock signal is a signal which is maintained at a first level during a normal mode and periodically changes during a low power mode.
