Abstract
A pixel driving circuit includes a data writing circuit, a light-emitting control circuit and a light-emitting diode chip. The data writing circuit is electrically connected to a first scanning signal terminal, a data signal terminal and a first node. The light-emitting control circuit is electrically connected to the first node, an enable signal terminal, a first voltage signal terminal and a second node, and is configured to transmit a first voltage signal received at the first voltage signal terminal to the second node. The light-emitting diode chip is electrically connected to the second node and a second voltage signal terminal. The light-emitting diode chip includes a plurality of light-emitting portions. The light-emitting diode chip is configured to drive the plurality of light-emitting portions to emit light in different periods of time respectively or drive at least two light-emitting portions to emit light in a same period of time.
