Abstract
Provided are a pixel driving circuit, a driving method, an array substrate and a display apparatus. The pixel circuit comprises: a data line, a gate line, a first power line, a second power line, a reference signal line, a light emitting device, a driving transistor, a storage capacitor, a reset unit, a data writing unit, a compensation unit and a light emitting control unit. The pixel driving circuit can compensate and eliminate the display nonuniformity caused by the threshold voltage difference of the driving transistors.
