Abstract

See full text

The present disclosure provides a pixel driving structure and a display panel. The pixel driving structure includes a pulse width modulation driving circuit, a pulse amplitude modulation driving circuit, and a buffer circuit. The pulse width modulation driving circuit is configured to control a pulse width of a driving current supplied to the light emitting device to be driven according to a pulse width modulation data voltage; the pulse amplitude modulation driving circuit is configured to control an amplitude of the driving current supplied to the light emitting device to be driven according to a pulse amplitude modulation data voltage; and the buffer circuit is electrically coupled between the pulse width modulation driving circuit and the pulse amplitude modulation driving circuit and is configured to adjust a rate at which the pulse width modulation driving circuit applies a pulse width modulation voltage to the pulse amplitude modulation driving circuit.
