Abstract:
1. An emission control signal generating circuit of a flat panel display comprising a plurality of pixels, each said pixel including a plurality of electroluminescent elements, a driving transistor, and a plurality of emission control transistors respectively connected to a corresponding one of the plurality of electroluminescent elements and the driving transistor to form separate current paths between the corresponding one of the plurality of electroluminescent elements and the driving transistor, such that a first current path is formed by the driving transistor, a first emission control transistor, and the electroluminescent element corresponding to the first emission control transistor, while a second separate current path is formed by the driving transistor, a second emission control transistor, and the electroluminescent element corresponding to the second emission control transistor, the emission control transistors being controlled by a plurality of emission control signals, the circuit comprising: a first signal generating device for generating one of the plurality of emission control signals as an output signal and for transmitting said output signal directly to at least one of the pixels for controlling a corresponding one of the emission control transistors of the at least one of the pixels; and a plurality of second signal generating devices for generating other ones of the plurality of emission control signals using the output signal of the first signal generating device and an external control signal, and for transmitting said other ones of the plurality of emission control signals to the at least one of the pixels for controlling other corresponding ones of the emission control transistors of the at least one of the pixels, wherein the external control signal used by each of the plurality of second signal generating devices corresponding to a same first signal generating device is the same signal.
