Abstract
The present disclosure provides a driving method of a display device and a display device. The driving method includes: sensing threshold voltages of the driving transistors of the plurality of pixel units and calculating an external compensation value for display data signal according to the threshold voltages of the driving transistors of the plurality of pixel units; performing an internal compensation on the threshold voltage of the driving transistor through the pixel driving circuit; and superimposing the external compensation value and the display data signal, wherein a data signal obtained by the superimposing is input into the pixel driving circuit for driving the light emitting element to emit light.
