Abstract: A manufacturing method for TFT array substrate and TFT array substrate are disclosed. After depositing an electrode material layer and a metal material layer on the gate insulation layer and the active layer in sequence after the active layer above the gate electrode is formed. A photoresist pattern is formed on the metal material layer. The photoresist pattern includes a first and second photoresist blocks with different thicknesses. The metal material layer and the electrode material layer are etched using the photoresist pattern to form a contact electrode and pixel electrodes connected with two ends of the active layer and the source/drain electrodes on the contact electrode. The process is simple and can effectively reduce the contact resistance between the source/drain and the active layer and improve the quality of the product.

Abstract: A display panel, an array substrate, and a manufacturing method thereof, wherein the array substrate includes a thin film transistor device, and an interface layer, a first transparent conductive layer, a passivation layer, and a second transparent conductive layer which are formed on the thin film transistor device in sequence. By replacing a planarization layer in the prior art with the interface layer, performing a gate re-etching process, and perforating the interface layer and the passivation layer to simultaneously form a deep via and a shallow via, a number of photomasks required to form the array substrate is reduced to 8. It effectively reduces costs of production materials and costs of photomasks.

Abstract: The present application provides a pixel driving circuit and a display panel. The pixel driving circuit includes an amplitude regulating module and a pulse width modulation module, where the amplitude regulating module and the pulse width modulation module are both electrically connected to a first node, so that the pulse width modulation module and the amplitude modulation module are configured to cooperate with a first data signal and a second data signal, respectively, to realize regulation of both the pulse width and the amplitude of the valid pulse of the driving current signal for driving the light emitting device to emit light. As such, the valid pulse of the driving current signal has different pulse widths and different amplitudes under correspondingly different gray scale states, so that the light emitting brightness and the light emitting duration of the light emitting device under correspondingly different gray scale states are different.
