Abstract
An OLED driving circuit is provided. The OLED driving circuit comprises a switch transistor, a storage capacitor, a driving transistor and a control module. In a charging time period, a charging switch of the control module is conducted to connect the storage capacitor and a first voltage end and a data signal is transmitted from the switch transistor to the storage capacitor. In a memory time period, a memory switch of the control module is conducted to connect the storage capacitor and an OLED and the data signal is transmitted from the switch transistor to the storage capacitor. In a light-emitting time period, three light-emitting switches are conducted to connect the driving transistor to the storage capacitor, the first voltage end and the OLED.
