Abstract:
A pixel cell driving circuit driving an organic electric lighting component comprises a first, a second and a third thin film transistors and a storage capacitor. The first thin film transistor is turned on or turned off under a control of a first scanning signal. When the first thin film transistor is turned on, the storage capacitor is charged by a data signal. The second thin film transistor is turned on under an action of the storage capacitor and drives an OLED. The third thin film transistor is turned on under a control of the second scanning signal when the first thin film transistor is turned off, and the storage capacitor is charged by a charging signal. The pixel cell driving circuit may effectively avoid the flicker due to the electrical charge leakage of the storage capacitor. The disclosure further provides a pixel cell and a pixel cell driving method.
