    摘要: A frame rate control (FRC) method is provided for driving a number of pixels according to a number of pixels data. The pixels include a number of first color sub-pixels. In this method, the dithering process is performed to the pixels data in two frames according to two basic matrixes respectively. In one of the two frames, the numbers of the first color sub-pixels, driven by the positive pixel voltages and the negative pixel voltages and to which the dithering process has been performed, are the same in substantiality. Further, in the other of the two frames, the numbers of the first color sub-pixels, driven by the positive pixel voltages and the negative pixel voltages and to which the dithering process has been performed, are also the same in substantiality.

    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.
