  • Patent number: 9839095
    Abstract: 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.

  • Publication number: 20140192038
    Abstract: The present invention relates to an OLED pixel driving circuit which has a data input unit for sending out controlling signals, a voltage storage unit for storing voltages from a first power source, a driving unit for receiving the controlling signals from the data input unit to selectively activate the voltage storage unit, a second power source providing a voltage to be stored in the voltage storage unit; and a switch connected to the second power source to offset potential loss of the first power source from the voltage stored in the voltage storage unit. The compensation circuit can not only compensate the non-uniformity of the threshold voltage but also eliminate the non-uniformity of the OLED display caused by the power IR drop, so that the effect of display of the OLED are maximally improved.
