Abstract:

The present disclosure relates to data driving circuits, display panels and display devices. In accordance with embodiments of the present disclosure, by periodically supplying a reset voltage to the subpixel SP in a holding interval of a period in which the display device is driven in a low-speed drive mode, it is possible to enable a waveform of luminance in a refresh interval to be identical to a waveform of luminance in the holding interval, and to prevent occurrence of flickers in the low-speed drive mode. In addition, by setting an optimal reset voltage in accordance with a driving voltage supplied to the display panel and changing the reset voltage for matching a changed driving voltage, it is possible to prevent flickers from being visible and to reduce power consumption through low-speed driving.
