An OLED pixel driving circuit includes a storage capacitor, a first switching circuit, and a driving element. The storage capacitor has a first node and a second node, where the second node receives Data voltage in a first period, and the first node receives reference voltage in a second period within the first period. The first switching circuit isolates the first node from a fixed voltage source in the first period, and connects the first node to the fixed voltage source to provide a fixed voltage to the first node after the end of the first period. The driving element outputs a driving current independently of the fixed voltage.
