Abstract:
A gate clock generator of a display device includes a carry clock generator configured to sequentially generate N carry clock signals based on a carry-on clock signal and a carry-off clock signal, a scan clock generator configured to generate N scan clock signals based on a scan-on clock signal and a scan-off clock signal, and a sensing clock generator configured to generate N sensing clock signals based on a sensing-on clock signal and a sensing-off clock signal. In a multi-clock mode of the display device, during an on period of a K-th carry clock signal, the scan clock generator outputs a K-th scan clock signal such that the K-th scan clock signal has a number of pulses that corresponds to a number of pulses of the scan-on clock signal in the on period of the K-th carry clock signal, and the sensing clock generator outputs a K-th sensing clock signal such that the K-th sensing clock signal has a number of pulses that corresponds to a number of pulses of the sensing-on clock signal in the on period of the K-th carry clock signal.
