Claim:
1. An inverting circuit, applicable to an active matrix organic light emitting display, comprising: a pull-up unit comprising first and second transistors, comprising: a pull-down unit only including third and fourth transistors and no other transistors, comprising: a first capacitor, wherein a first terminal of the first capacitor is only electrically connected to the second terminal of the pull-up unit and the fourth terminal of the pull-down unit, and a second terminal of the first capacitor is electrically connected to the third terminal of the pull-up unit and the sixth terminal of the pull-down unit, wherein the first terminal of the pull-up unit is a level signal input terminal, and the fifth terminal of the pull-down unit is a clock signal input terminal repeatedly receiving a clock signal in a frame period, the first control signal input into the level signal input terminal of the pull-up unit and the second control signal input into the clock signal input terminal of the pull-down unit are not inverted signals, and the pull-down unit only has one clock signal input terminal.
