Abstract
A pixel driving circuit and method, an array substrate, and a display apparatus, wherein the pixel driving circuit comprises a data line, a first scan line, a signal control line, a light emitting device, a storage capacitor, a driving transistor and four switching transistors. The pixel driving circuit can avoid the influence on a driving current of an OLED caused by threshold voltage drift of a driving transistor, and improve the uniformity of a displayed image.
