Pixel driving circuit and driving method therefor, array substrate and display apparatus

Abstract

A pixel driving circuit comprises: a data line (Data), a first scan line (Scan[1]), a second scan line (Scan[2]), an enable control line (EM), a power supply line (Vdd), a light emitting element (D), a display sub-circuit (1) and a photosensitive sub-circuit (2); wherein the display sub-circuit (1) is connected to the data line (Data), the first scan line (Scan[1]), the second scan line (Scan[2]), the enable control line (EM), the power supply line (Vdd) and the light emitting element (D), and is configured to drive the light emitting element (D) to emit light for display under the control of the first scan line (Scan[1]), the second scan line (Scan[2]), the enable control line (EM), the data line (Data) and the power supply line (Vdd); and the photosensitive sub-circuit (2) is connected to the data line (Data), the first scan line (Scan[1]), the second scan line (Scan[2]) and the enable control line (EM), and is configured to sense a touch action under the control of the first scan line (Scan[1]), the second scan line (Scan[2]), the enable control line (EM) and the data line (Scan[1]).
