PIXEL DRIVING CIRCUIT AND DISPLAY PANEL

摘要

A pixel driving circuit includes a light-emitting working unit, a driving unit, a data signal input, a initial voltage input, a driving power input and a plurality of control level inputs. The driving unit includes a voltage storage element and a driving element. The driving element includes a first electrode, a second electrode and a control terminal. One end of the voltage storage element is connected to the control terminal of the driving element. The first electrode of the driving element forms a first input port of the input port of the driving unit. The pixel circuit is capable of improving the display effect and improving the display life of AM-OLED.
