摘要： Disclosed are a pixel driving circuit, a driving method and a display panel. The pixel driving circuit includes a pulse amplitude modulation driving circuit, a pulse width modulation driving circuit and an anti-leakage circuit. The pulse amplitude modulation driving circuit is configured to control an amplitude of a driving current provided to a light-emitting device to be driven. The pulse width modulation driving circuit is configured to control a pulse width of the driving current provided to a light-emitting device to be driven. The anti-leakage circuit is electrically connected between the pulse amplitude modulation driving circuit and the pulse width modulation driving circuit. The anti-leakage circuit is used for cutting off a current leakage path between the pulse amplitude modulation driving circuit and the pulse width modulation driving circuit.

摘要： The present application discloses an array substrate and a display panel. The array substrate includes a plurality of pixel units arranged in an array, each of the pixel units includes a thin film transistor. The thin film transistor includes a gate electrode and a drain electrode. A first overlap region and a non-overlap region is defined between the gate electrode and the drain electrode. The first overlap region is adjacent to the non-overlap region. A width of a cross section of the drain electrode in the first overlap region is less than a width of a cross section of the drain electrode in the non-overlap region. The array substrate can reduce a parasitic capacitor between the gate electrode and drain electrode.
