ABSTRACT:
A driving circuit for a display device includes a first trigger signal generating stage, a second trigger signal generating stage, . . . , and an n-th trigger signal generating stage, where n is an integer larger than 0. The i-th shift register performs a tri-state inversion on an input signal of the i-th trigger signal generating stage to obtain an i-th tri-state inversion signal, and then performs the tri-state inversion on the i-th tri-state inversion signal to obtain an input signal of the (i+1)-th trigger signal generating stage. The i-th logic gate generates an i-th logic signal according to the i-th tri-state inversion signal and the input signal of the (i+1)-th trigger signal generating stage. The (i−1)-th trigger signal generating stage generates an (i−1)-th trigger signal generating signal according to the i-th logic signal.
