The invention discloses a display panel and a driving method thereof, a driving
chip and a
display device, the display panel comprises a sub-pixel, the sub-pixel comprises a pixel circuit and a light-emitting element, the pixel circuit accesses a light-emitting
control signal and a first scanning
signal, the light-emitting
control signal is used for controlling whether the sub-pixel emits light or not, and the first scanning
signal is used for scanning the sub-pixel. The first scanning
signal is used for controlling whether the
data signal is written into the pixel circuit; the working
modes of the display panel comprise a first mode, a second mode and a transition mode, the transition mode is located between the first mode and the second mode, and the first mode is before the transition mode; in the transition mode, the light-emitting
control signal comprises an integer number of pulses, the first scanning signal is a
cut-off level, and the pulses of the light-emitting control signal comprise a conduction level and the
cut-off level. According to the display panel and the driving method thereof, the driving
chip and the
display device provided by the invention, the
flicker problem caused by switching of different
modes can be avoided.
