摘要: The main differences between the present invention the conventional pixel circuit for active matrix of current driving device is the usage of the auxiliary transistor(s). In the invention, at least one auxiliary transistor is used to separate both the transistor, which is directly electrically coupled to the current driving device, and the plate, which is not directly electrically coupled with a constant voltage source, of the capacitor from the other transistors of the pixel circuit. Hence, all circuit and voltage, which are induced by the switching process of these transistors, are blocked or compensate by the auxiliary transistor(s), and the stored voltage of the capacitor would be unaffected.
